A plurality of nozzles (136) jet-spray cooling or heating water onto the product (108) as it is conveyed along the trough (120). The nozzles (136) are oriented in opposing first and second series so as to impart a rotation on the bagged product (108) generally about a longitudinal axis of the trough (120). According to one embodiment, a first suction tube (230) having openings through the trough (120) wall is opposite to the first series of nozzles (136) and with a first pump (236) forms a first fluid circuit. Similarly, a second suction tube (264) with suction openings, together with a second pump (258) and the second series of nozzles (136) form a second fluid circuit. The two fluid circuits keep the bags (108) centered in the trough (120), surrounded by cooling or heating water. According to a second embodiment, the trough (120) is positioned in a sump (190) and has trough openings so that the water in the trough (120) communicates with that in the sump, and the suction tubes (230, 264) are not used.

Description

CONSTRUCTION OF A HEAT TRANSFER LINE Background of the Invention Many food products today, such as tomato paste, orange juice, crushed pineapple and sliced tomatoes, are cooked and filled hot in flexible bags. Containers with hot product (food products) must then be cooled for later handling and storage. An example of the prior art system for cooling the contents of flexible bags is shown in FIGURE 1, generally at 70. Referring to this, the bags 72 enter the open plastic band conveyor 74 at one end in a first cooling station as shown generally at 76. Station 76 is shown in isolation in FIGURE 2. Bag 72 is in a cooling water bath 78 at approximately its mid-point. Sprinklers placed above 80 spray cooling water on top of the bags 72. The bag 72 is transported by the mechanical action of the conveyor 74 to a gate 82 at the end in front of the station. The gate 82 is formed by three rollers i that rotate upwards, stacked 84, 96, 88. The actions of the conveyor 74 and the rollers 84, 86, 88 cause the bag 72 to rotate or turn, as shown by the arrow 90, about an axis generally perpendicular to the direction of travel of the conveyor 74 to thereby partially mix the contents of the bag and expose the bottom surface of the bag to the cooling water of the sprinklers 80. The gate 82 is rotated then down as shown by arrow 92, and bags 72 are transported together to the next station for a subsequent cooling process, and so on through the twelve or more stations. There are numerous problems with the prior art system 70. One is that the total process of the system 70 is slow. It takes about 40 minutes to cool the contents of bag 72 from two hundred degrees (93.3 ° C) to below one hundred twenty degrees Fahrenheit (49 ° C). Another problem is that the bags 72, and particularly when they are not full, occasionally get caught in the rollers 84, 86, 88 and break, spilling their contents. A further disadvantage of the prior art system 70 is that it occupies a large amount of floor space since it is approximately 21.3 m (seventy feet) in length. Other systems for cooling or heating the contents of flexible containers are shown in the following United States patents; 4,383,463 (Rica et al.), 5, 009, 150 '(Andersen) and 5,370,174 (Silverstrini et al.). The content of each of these patents and all other patents mentioned in this description are hereby incorporated by reference in their entirety. Examples of constructions for heat transfer and for transporting products known in the prior art are described in the following U.S. Patents: 5,377,492 (Robertson et al.), 5,809,787 (Zittel), 5,417,074 (McAfee et al.), 5,351,495 (Lermuzeaux) , 5,269,212 (Engler), 4,858,445 (Rasovich), 5,630,327 (Kicsek et al.), And 4,403,479 (Rasovich).

Brief Description of the Invention Accordingly, the present invention is directed to heat transfer line constructions. A preferred heat transfer line construction mode includes an elongated line placed in a collecting structure with the line is approximately 30.48 cm (one foot) above the bottom of the collecting structure. The outlet end of the line or tunnel is spaced a distance from the outlet end of the collector structure. An extraction conveyor transports objects, such as flexible bags containing flowable liquid or semi-liquid product, from the outlet end of the line or tunnel and out of the collecting structure. A first and second series of nozzles are placed along opposite sides of the line or tunnel and inject liquid laterally into the line. They preferably direct the liquid towards the liquid in the line or tunnel and below the level of the liquid. According to a preferred modality, a series of nozzles is separated one above the other, thus imparting a rotary movement on the objects transported around an axis generally parallel to the longitudinal axis of the line, ie along the transport path. The liquid is injected at the entrance end of the line or tunnel to transport the objects along the transport path line) and towards the nozzles (to rotate the objects when they are transported downwards, towards the line). The present invention also relates to providing efficient means for cooling (and / or heating) the contents of flexible containers or bags. The bags with their contents are dropped at a feed end of a line containing cooling water. The bags are advanced from one station to the next on the line by the periodic actuation of a fluid jet conveyor at the inlet end of the line, as mentioned in the previous paragraph. After the bags are advanced to their respective next stations, the fluid jet conveyor is interrupted and the fluid nozzle system is turned on. The fluid nozzle system includes a first series of nozzles on one side of the line and directed towards the line and a second series of nozzles on the other side of the line and equally directed towards the line. The first series of nozzles is arranged in a horizontal plane approximately five or more nozzles of the first series collides against the adjacent side of the bag approximately 5.08 cm (two inches) above the midline of the bag, and the water of the five or more nozzles of the second series collides on the side opposite of the bag, approximately 5.08 cm (two inches) below the median line of the bag. The two sets of opposite and deflected nozzles have two actions on the bag. First, they collide and push on the side of the bag, approximately 30.48 cm (twelve inches) for example, on each side. This "massage" action causes the central contents of the bag to move away from the center of the bag and towards the side of the bag, thereby promoting the transfer of heat from the central contents of the bag to the cooling water in the bag. the surface of the bag. Second, it causes the bags to rotate about an axis generally parallel to the axis of the line. This rotation movement in the cooling water bath in the line also helps cooling the contents of the bag. Additionally it is within the scope of the invention to orient the nozzles of The bags generally come into contact with one another end-to-end as they move from station to station in the line of the present system, and neither gates nor other structures separate them from adjacent pockets. The movement of the bags, towards, along and out of the line is now described with the respective bags in the three active stations on the line and one in the rampant station ("dead zone") at the exit end of the line. line and with the nozzle system deflected on. A detector in a feeding station above the inlet end of the line detects the arrival of a hot filled bag. When this is detected, the cooling water flow is changed from the diverted nozzle system to the fluid jet conveyor and the first extraction conveyor is turned on. The bag in the rampant station is pushed over the first extraction conveyor and transported away from it. The three bags in the line move to their respective respective stations due to the action of the fluid jet conveyor. A detector The first feeding station is then emptied, and the hot filled bag detected by the detector of the feeding station slides down, towards the first feeding station. In this way, the bags are now in the three active stations and in the rampant station. The bag in the rampant station acts advantageously as a plug or a soft gate, blocking the further advancement of the bags relative to the heat transfer line. The detector of the feeding station detects that f no hot bag is in or near the feeding station, and causes the cooling water to change and flow into the nozzle system and not the fluid jet conveyor. The three bags in the three active stations are therefore subjected to massage and rotation. When the detector of the feeding station detects the arrival of another hot filled bag, the process starts again. A centrifugal pump pumps the cooling (water) or (heating) fluid from a cooling tower to a butterfly valve, which directs The center of the impeller can be seen when looking down towards the suction line in the direction of the liquid flow. U.S. Patent 4,981,413 calls this the "center of the pump impeller". (In contrast, see U.S. Patent 3,575,521). A low pressure check valve prevents air from being sucked into the pump through the purge tube. Bleeding the air cavities in the pump prevents the pump from losing its preparation or priming. This pump arrangement of the invention, besides being used in the heating / cooling environment of the present, can be used on board of vessels where the suction of the pump can be exposed in a rough sea. This can be used, generally in any application where the level of supply is difficult to control and the pump loses its preparation or priming when it traps air in the suction line. An exemplary method for reconverting such a pump according to the present invention first removes the suction line from the pump. The purge assembly is then a flanged purge tube or a flange purge tube can be used with a flange adapter. Next, the line of the purge tube extends until it is as close as possible without actually touching the impeller. The suction line is then reconnected (it will probably be necessary to reinstall it to shorten the suction line due to the space occupied by the purge tube). It may be necessary to connect the outlet of the check valve to a drain. The operation of the purge assembly is then verified by starting the pump, introducing air into the pump so that it loses its priming, stopping the introduction of air and ensuring that the pump "belches" the air bubble through the purge pipe and win your priming again. Instead of cooling the contents of a flexible bag, it is also within the scope of the invention to heat the contents of the bag. More specifically, a large flexible bag is filled with non-sterile product. The bag is sealed (or otherwise closed), and the (sealed) bag is loaded in a line similar to that of the cooling system of the invention It hits the opposite sides of the bag, massaging it and moving its central content towards the surface or skin of the bag. The bag is also rotated therefore. Heating is effected rapidly before the contents of the bag become a mess, as would happen if the slower prior art system 70 used the product at room temperature and hot water. The cooling can be effected, and the bags then encased, providing a very economical replacement for the cans. Small bags at a slow production speed can be packaged manually in boxes. However, at faster speeds and / or larger bags, automatic case packers can be used, such as those currently available from FMC, Hayssen and Scholle. Also disclosed herein is a novel nozzle assembly useful in the heating and cooling systems of this invention for heating or cooling the contents of flexible containers and in other applications where a desirable focus fluid flow will be apparent to those skilled in the art. The assembly of gradually to increase the speed of the fluid that flows through it approximately ten times. Approximately, the elastomeric coating of the inner surface acts as an inner "skin" which prevents the feedback or accumulation of turbulence itself and therefore increases the power of the fluid released by the nozzle assembly. The first sleeve has a first rear attachment, and the second sleeve has a second front attachment. The clip encloses the first and second accessories, keeping them together with the collar sandwiched between them. In consecuenseAnother way of defining the present invention is that the shape and movement of the flexible bags are carefully controlled to maximize the heat transfer to the contents of the bags to heat or cool the contents quickly, efficiently and perfectly. This is preferably done using water jets, although other means such as mechanical means, including rollers, as would be apparent to those skilled in the art of this disclosure are also included here. One way to adjust the the bag. The action of the massage (or deviated forces) can also be effected with a force on the bags causing them to rotate, preferably in a bath of heating or cooling fluid. A further definition of the invention is the use of the heating or cooling fluid (e.g., liquid and specifically water) as the heat transfer medium for heating or cooling the contents of the flexible containers and also as means for changing the shape and / or movement of flexible containers to improve the transfer of heat to their contents. The fluid therefore serves two functions. The fluid can additionally serve as the driving force (a third function) to move the containers from one work station to the next. The invention can thus be used to heat and / or cool the contents of flexible containers. One embodiment fills the bags with hot product, closes the bags and then cools them according to this invention. This modality fills the bags with product at a cold or ambient temperature, closes invention. Alternatively, they can be cooled by other means as would be apparent to those skilled in the art. In other words, a fluid transport jet is described which moves flexible containers or bags along a line from one station to the next on a line in a process, which efficiently heats or cools the contents of the lines. containers. The lateral fluid jets placed along the opposite sides of the line direct the heating or cooling fluid (water) over the flexible containers in the stations. They direct the fluid generally in horizontally separated planes over the flexible containers between them by (1) making the central content of the containers move away from the central areas of the container sideways to promote the transfer of temperature between the contents and the fluid cooling or heating of the fluid jet conveyor and the fluid jet and (2) the containers for generally rotating around axes parallel to a longitudinal axis of the line helping lateral act alternately, whereby the fluid transport jet moves the flexible containers from one active station to the next, and in each active station the lateral fluid jets are activated to massage the central contents towards the container cover and spin the containers in the cooling or heating fluid in the line. It results the cooling or total and efficient heating of the product in the flexible containers. A system for cooling (or heating) bagged product using the cooling (or heating) fluid that has impact on and bathes the bagged product. The bags are transported down to a tubular or closed line and are periodically stopped at different stations along the tube. A pair of discharge tubes are placed on opposite sides of the tube, each tube having a series of nozzles projecting towards the tube. In each station, both series of nozzles spray by means of a cooling jet (or heating) in the tube and against the flexible bag. The two sets or games of thus efficiently heating or cooling the product t. Cooling or heating in the tube and surrounding the bag remains with the bag during the rotation of the bag, producing reduced friction lubrication with the tube walls. The first and second rows of friction parallel to the tube have openings towards the tube, sucking hot (or cold) water away from the bag. The first and second suction lines are placed diametrically opposite the first and second series of nozzles, respectively. In this way, the fluid flow is generally from the nozzles of the first series around the outer side of the bag in the direction of the rotation of the bag against the tubular wall, about one hundred sixty degrees and out of the openings in the first suction line, and similarly of the nozzles of the second series around the outer side of the bag in the direction of rotation of the bag against the tubular wall, approximately one hundred and sixty degrees and out of the openings in the second suction line. of suction to the second set of nozzles. The cooling (or heating) system of the present also includes means for removing (or adding) heat from (or to) the fluid from the suction lines before pumping it into the discharge tubes. If the bag advances towards the openings in the first suction line, the first pump stops or becomes slow and the second set of nozzles pushes it towards the other side of the tube. Therefore, the bag tends to be centered on the tube or oscillate slowly side by side in the tube. The tube of transport of bagged product besides being straight can be angled. For example, when angled at ninety degrees, a deflection jet in line with the output shaft helps advance the bags around the corner when indicated to be so. When the cold (or hot) bag comes out of the transport tube it is important that it is oriented correctly. This can be done by passing it through an elliptical opening which is facing downwards or using fluid jets together with an elastomeric gasket sandwiched between the opposing mounting faces of the adjacent sections. The joints have openings for the pressure line and the suction line aligned with the pressure tubes and the suction lines. The synchronization of the pumps in the different cooling stations can be by any of three methods. A first preferred method is to provide a separate deflection pump (main bag transport), which is ignited to advance the bags along the tube. A second method is to use a bypass valve, and a third method is to bypass the external pressure manifold with a jet assist valve. Other objects and advantages of the present invention will become more apparent to those skilled in the art to which the present invention pertains from the following description taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION A system of the present invention for heating or cooling flexible containers or bags is illustrated in the drawings of FIGURES 3-7 generally at 100. Referring to these, the bags are filled with the hot product on the filling table described generally at 104. The filled bags 108 are dropped one by one onto the feed conveyor 112 where they are slowly transported to the feed ramp 116. They fall from the feed ramp 116. towards a horizontal cooling (or heating) line 120. Briefly, in the cooling line 120, two fluid systems act on the bags 108. The first is a nozzle system generally shown at 124, which includes two manifolds or tubes 128 and 132, each on an opposite side of the cooling line 120 and each having a series of separate nozzles 136 for its length You. (The construction of the nozzles 136 is shown in more detail in FIGURES 26-28). Although the tubes 128 and 132 are preferably both horizontal and their nozzles 136 are positioned horizontally, the tubes are placed in different horizontal planes, i.e., vertically offset from each other. The other fluid system is a fluid jet conveyor 140 at the inlet end of the cooling line 120 and which transports the filled bags 108 toward the outlet end of the line. At the exit end, the cold bags 108 are collected by a first discharge conveyor 142. The first discharge conveyor 142 transports the bags 108 to a second discharge conveyor 144, which in turn transports them to their drop end. from the bags where they fall to a 208.17 liter (55 gallon) drum 148. An air drying area is positioned at the adjacent ends of the first and second discharge conveyors 142, 144. An air plenum 149 (FIGURE 25) supplies approximately 1,406 kg / cpr (2 psi) of air at high volumes to air blades that blow the water out of the bags 108 in this air drying area. The motor 149 can be a regenerative type blower of 10 horsepower. An optional detector (photodetector) 150 can be provided (FIGURE 24) for the fall and safe accumulation of the bag i on top of the second discharge conveyor 144. The displacement time of 208.2 liters (fifty-five gallons) 108 of the system 100 is thirteen to fifteen minutes (eight minutes of retention, plus five minutes of cooling, plus one minute of transportation) from the filling table 104 to the drum of 208.2 liters (fifty-five gallons) 148. The variation of time is caused by the accumulation of the bags on the discharge conveyors 142 , 144. The time of the feed ramp 116 to the discharge conveyor 142 is only five to seven minutes. The filling table 104 is a short conveyor having a motor 154 mounted on weight cells with a robotic bottle opener / filler placed thereon, as is known in the art. The filling table 104 includes an engine 156 as described in FIGURE 24. The operator places a bag in the device, the lid is removed automatically from the bag and insert the filling tap. The filling sequence continues until the correct product weight has entered the bag. At that moment, the filling stops, the tap is removed, and the bag is covered again and released. An on button notifies the operator that the bag 108 is ready to advance to the feed or hold conveyor 112. The operator presses a button causing a short conveyor to turn the bag 108 downward onto the retainer conveyor 112. Orientation with the face downward / downward accessory causes the attachment to heat to a sterilization temperature as it slowly moves toward the conveyor 112. When a filled, hot bag (E) slowly reaches the top of the conveyor 112 (which is driven by motor 160) as shown in FIGURE 8, the following sequence is started. The arrival is detected by a detector 162, which through a computer 164 (FIGURE 23) causes the flow of the cooling fluid (cold water) to be changed by a throttle valve 165 of the nozzle system 124 photodetector, but this may alternatively be a capacitance probe, a proximity switch, a retroreflector photodetector, a metal oxide fiber switch, an ultrasonic sensor, a micro switch with rollers, a load cell below the conveyor to detect stress by weight , a sensor that detects current changes in the drive motor of the conveyor or any other "detector" as would be apparent to those skilled in the art. The detector 162 also causes the motor 163 of the first discharge conveyor 142 (the extraction conveyor) to be ignited or activated. The combination of the water fluid induced by the fluid jet conveyor and the displacement of the first discharge conveyor 142 pushes the end of the bag (A) in the dead station 166, as shown in FIGURE 8, on the first conveyor of discharge and then on the second discharge conveyor 144, which is driven by a motor 168 (FIGURE 24). A detector 170 associated with the first conveyor (or second discharge conveyor) 142 (or but it can be any of the other detectors listed above with respect to the detector 162. Like a bag (A) outside the cooling line 120, the remaining three bags (B, C, D) advance 1.22 m (four feet) to their following respective stations, as shown in FIGURE 9. This advance of 1.22 m (four feet) makes room at the feed station 184 of line 120 for the incoming bag (E). The incoming bag (E) thus moves slowly over the feed conveyor 112 so that there is time for the process described above to empty the feed station 184 before the incoming bag slides out of the feed conveyor, towards down ramp 116 and towards the feeding station. When the bag (E) slides towards the feeding station 164, the flow of the fluid jet conveyor 140 preserves the bags (B, C, D) moving towards the outlet end of the cooling line 120. It is prevented that the bags 108 spring end to end by the narrow diameter of the line; this is important because the users Feeding for proper sterilization. When the tail of the bag (E) passes the detector 162, the computer 164 causes the bypass valve 165 to reverse the bypass state and send pressure back to the nozzle system 124. Referring to FIGURE 11, the cooling line 120 has bags (B, C, D) in each of the four seasons. The bag (B) in the dead station 166 acts advantageously as a soft plug or plug (resembling a stranded whale) blocking the forward movement of the three bags (C, D, E) in the three active stations. That is, the three bags (C, D, E) are end to end on the narrow line 120, preventing the bags from overlapping one another, which would result in a consistent and ineffective cooling of the contents of the bag. bag. The nozzles 133 of the tubes 128 and 132 do not extend towards the dead station 166. The cooling line 120 is perforated to allow the cooling fluid to escape in the line towards the collector 190 downwards. The manifold 190 is preferably a stainless steel container cooling 120 in the dead station 166 is cut diagonally upward at the end 192, so that the discharge or extraction conveyor 142 can efficiently collect the bag in the dead station 166 and transport that out of the cooling line 120. The conveyor Extraction 142 has a slope of approximately twelve degrees, since a larger slope of approximately sixty degrees would result in the bag breaking the static friction of the conveyor and sliding back down to line 120. In this way, dead station 16 is important because it allows a bag that has been cooled to act as a plug or plug or soft gate that holds the other three bags in the three active stations behind it. This importantly provides a smooth transition and stopping of the bags in the cooling line 120. Of course, more or less than three active stations may be provided as required. Since the tubes 128 and 132 of the nozzle system 124 are deflected, the fluid action of the This causes the hot contents in the center of the bag 108 to be moved outward, towards the bag cover, where it can be cooled more quickly by the cooling water bath of the cooling line 120. In other words, the nozzle system 124 produces a massaging action on the bags 108, moving the hot contents of the middle part of the bags towards the flexible covers of the bags to promote faster cooling, thus solving the problem of the prior art of the final cooling of the central content. The water from the jet nozzles 136 should push the surfaces of the bags 108 as much as possible. Although the preferred fluid of system 100 is water, other liquids such as brine or oil may be used as would be apparent to those skilled in the art. The greater or deeper the fertilization of the bags 108, the greater the internal circulation of the contents of the bag. The surface can be pushed as much as the radius of the free floating bag for 208.17 liters (55 gallons) and 18.92 liters (5 gallons) 108 bags. of 208.17 liters (55 gallons) 108 is a dent of approximately 30.48 centimeters (12 inches). Another description of the depth of the dent or indentation is approximately 40% of the floating free diameter of the bag 108. The second action of the nozzle system 124 on the bags 108 is a rotating action, which can be understood from FIGURES 12-16, by arrow 194. The rotation is about an axis of the bags 108 which is parallel to the longitudinal axis of the cooling line 120, or in other words, parallel to the path of displacement of the bags caused by the periodic actuation of the fluid jet conveyor 140. The rotation circulates the bag 108 within the surrounding cooling water in line 120, thereby promoting efficient cooling, in addition to assisting the massaging action. The bags 108 can be rotated at half revolution per second or thirty revolutions per minute. Thus, for a drive period of less than 2 minutes, this means approximately fifty rotations in each of the The number of stations and the time in each station are selected according to the desired product and to provide enough cooling to remove enough heat to avoid degradation of the product but no more cooling than necessary. A range of workhorse rotations for typical products is between twenty and thirty-five rotations per minute with a preferred speed being thirty rotations per minute, which cools faster than twenty rotations per minute. The time consumed by the bags 108 at each station is determined by the frequency of arrival of the bags at the feeding station 184. For example, the system 100 can be designed for a retention time of 1.5 minutes per station, and initially used at 3 minutes per station and subsequently at a frequency of 1.5 minutes per station. FIGS. 12-16 show a preferred arrangement, where the nozzle 136 on the opposite sides of the bag 108 are parallel to each other. This provides the best rotation or rotation of the bags. These arrangements are also within the scope of the invention, however. By FIGURES 17a-17b. The arrangement of the top view 200 of FIGURE 17a would probably provide good mixing and thus cooling (or heating) of the product. The array 204 of FIGURE 17b works, although it suffers from a reduced rotation of the bag. The array 208 of FIGURE 17c massaging the contents of the bag but does not effectively rotate the bag. More than two nozzles can work according to what is illustrated by arrangement 212 of FIGURE 17d. Although the nozzles of the array 212 should be symmetrical, preferably they should not be directed straight but at an angle (eg, fifteen degrees) deviated from the center to impart torsion to the bags (108). The containment container or heat transfer line 120 is placed around the bags 108 to prevent them from moving away from the nozzles or jets 136. The nozzles 136 work well in the range of one-third to two-thirds of the line radius deviated from the horizontal center line. Less than a one-third radius ensures the rotation of the bag. And more than one deviation of two thirds creates little fertilization of line (120) of 0.9 and a workable interval is from 0.8 to 0.95. (See FIGURE 29a). Too much clearance (as shown by arrangement 200 in FIGURE 29a) allows the bag to "hide" in the line of the jets or nozzles 136 and not rotate. According to what is described in FIGURE 29b, very little slack results in the bag 108 being pulled against the wall of the line 120 and not rotating. The aforementioned preferred ratio and range are affected by the percentage "filling" of the bags (108). The bag diameters discussed above are the "free float" diameters and a typical filling of sixty percent of its final burst volume. A sixty percent fill allows a lot of slack, which causes the bag to flex when it floats freely and allows the massage action of the nozzle system 124 to work effectively. Referring to arrangement 204 of FIGURE 29c, a 208.17 liters (fifty-five gallons) 108 bag has a width (plane) of 93.98 centimeters (thirty-seven inches) or a diameter of 59.84 centimeters (23.56 inches) that works in a container with a diameter of Preferred bags that can be used with the 100 system are the current 208.17 liters (fifty-five gallons) bags constructed of two layers of polyethylene covered by a layer of polyester or nylon, 5.92 gallons (five gallons) bags comprising two polyethylene layers, single-ply bags of 11.35 liters (three gallons) and bags of 3,785 liters (one gallon). In other words, the bags can be made of a plurality of layers with the majority of the layers made of polyethylene, and the outer layer can also be made of nylon to add strength. A full bag has an elliptical cross section flattened at the bottom. A bag of 208.17 liters (fifty-five gallons) is approximately 17.78 centimeters (seven inches) thick, 86.36 centimeters (thirty-four inches) wide and 139.7 centimeters (fifty-five inches) long. Those dimensions are maximum because the surface is constantly curved, trying to form a sphere. A bag of 18.9 liters (five gallons) is approximately a model on a scale of one eleventh of a bag of 208.2 containers in the form of a flexible bag. The lower the viscosity of the product, the better the heat transfer. Most food products (including tomatoes, chilies and peaches) can be used. The product can also be non-food, such as blood plasma, corrosive chemicals and reagents for chemical reactions to produce a finished product. Highly viscous or thick products, such as Karo syrup, need considerable power to massage the bag, receiving high nozzle pressures. The nozzle pressures from 2.1903 to 8.4372 kg / cm * '(thirty to one hundred twenty psi) work well with the 100 system. Although the pressure can be greater than 8.4372 kg / cm2 (one hundred twenty psi) to 21.093 or 28.124 kg / cm (three hundred or four hundred psi), pressures generally greater than 31.6395 kg / cm2 (four hundred and fifty psi) would have enough energy to cut or otherwise damage typical bags. The force provided to the bags depends on the distance from the tip of the nozzle 136 to the surface of the bag 108, which has a plastic limit of approximately 2.54 centimeters (one separated every 20.3 cm (eight inches). The tests using a separation of 30.5 c ?. (twelve inches) for bags of 208.2 liters (fifty-five gallons), a separation of 7.6 cm (three inches) for bags of 208.2 liters (fifty-five gallons) and 10.2 cm (four inches) for bags of 18.92 liters ( five gallons) have been successful. It is also within the scope of the invention to arrange the nozzles 136 so that the direction of rotation of the bag 108 caused by the action of the nozzles 136 changes from station to active station. In this way, the cooling water (or other cooling fluid) leaves the nozzles 136 and collides with the bags 108. It then escapes through the perforations in the cooling line 120 and to the surrounding collector 190. The water flows towards the discharge end of the manifold 190 and towards the extreme suction line (or alternatively, lateral) or (from Schedule forty PVC) 230. From the suction line 230 the water flows to two pumps of the circulation collector (Teel brand) 236, which pumps the water upwards, towards a fan 250 (FIGURES 4 and 25). The water is cooled in tower 242 to a wet bulb temperature of about 21 ° C (seventy degrees Fahrenheit). The water has been heated approximately four to ten degrees in the system before it enters the cooling tower 242. (See, for example, FIGURE 6). The temperature rises depending largely on the flow velocities of the nozzle and the level of the fluid on line 120. The cooled water of tower 242 flows in tubes 256 towards the suction of the three pressure pumps (upper head Goulds blue) 258. Pumps 258 pump water through the gray sixteen inch (26.2 cm) pipe (Schedule eighty PVC) to the manifold under feed conveyor 112. The normal flow in that manifold is divided into two multiples. or tubes (PVC Schedule eighty, gray, 10.2 cm (four inches)) 128 and 132 that house the pressure nozzles 136. As discussed at the beginning, the butterfly valve (15.2 cm (six inches)) 166 is activated by the detector (photodetector) 162 and when it is opened cooling passage 120 by the fluid jet conveyor 140. In this way the flow forces the bags 108 to the passages 128 has advanced to their respective respective stations and makes room at the feeding station 184 for the incoming hot filled bag 108 of the feed conveyor 112. Thus, the pressure pumps 258 provide water at alternating loads, at know the cooling jet conveyor 140 and the nozzle system 124. When the system changes between the two? loads, the resistance to the flow changes. This resistance combined with the occasional influx of air into the suction manifold system of the cooling tower 242 causes air swallows to enter the pressure pumps 258. The air bags cause the pumps 258 to lose their priming. Then the intervention of the operator is required to purge the air to make the pumps 258 work again. The present invention solves this problem. The pumping system as described below has applications in other types of systems where priming was lost, interruption is not a practical option.

Figure of the drawings are the following components of the pump: motor face 262, pump housing or housing 263, motor shaft 264, arrow seal 265, impeller 266, static purge hole 267, suction line 268 , wear ring 269 and discharge hole 270. Purge tube 261 is placed in the eye of pump 258 and near screw head 271 to cause all air to exit. The water flow is shown by the arrow 272 and the air flow by the arrow 273. Although there are purge orifices 267 at the outer extreme edges of the housing or casing of the pump 263, they are only effective in a non-rotating system. Thus, in order to purge a centrifugal (rotating) pump in operation, the inventor has discovered that the air has to be purged from the pump eye 258 (see U.S. Patent 4,981,413). When the impeller 266 rotates and there is no fluid flow through the pump 258, there is essentially a centrifuge which directs the heavier water outwardly, thereby displacing the air outwardly. The only place for the The purge tube 261 passes upwards, out of an opening in the suction line 268 and is secured in position thereto with a side opening with coupling screw cap 274 and a compression cap 275. The check valve 260 it is a forward deflection check valve positioned at the end of the purge tube 261 and may be a flap or butterfly valve or a small globe valve. Thus, this light stopper check valve (0.0703 to .35155 kg / cm2 (one to five psi)) 260 leaves air out of the purge tube 61 but not inside and is necessary due to Venturi affection in the eye that creates a vacuum that tends to suck air into the pump. Pump 258 may be the Model # 3656 pump manufactured by Goulds P? Mps, Inc. of Seneca Falls, New York This pump has an impeller diameter of 20.5 cm (8-1 / 16 inch) and a size of 3.8 x 5.1-7.6 cm (1- 1/2 x 2-3 inches). The volume of air that causes this pump to lose its priming is 200 to 300 milliliters. That volume depends, however, on the size of the pump, the design of the impeller, the viscosity of the fluid, the near the impeller can be used. Most single-stage centrifugal pumps are of this type. A system for installing the purge tube 261 and the check valve 260 to the pump 258 is illustrated in Figures 20a-20e. For this system the purge tube 261 is mounted in a retrofit housing 276, as best shown in FIGURE 19. The horizontal portion 277a of the purge tube 261 is generally mounted in the center in a horizontal channel 278 through the housing of reconversion 276. Purge tube 261 may have a diameter of 0.64 cm (one quarter of an inch), while channel 278 and suction line 268 have larger 5.1 cm (two inches) diameters. The vertical portion 276 of the purge tube 261 is secured in an upper opening in the housing 276 with the check valve 260 positioned outside the housing. FIGURES 20a-20e show the steps of a reconversion process of the present invention. FIGURE 20a shows the pump 258, to be reconverted with its engine 279, the impeller 266, the discharge orifice 270, the housing or casing of the pump 263 and the line FIGURE 20c. The connection can be by threaded means for smaller pumps (up to 3785 liters per minute (thousand gallons per minute)) and by means of flanges for larger pumps. Connection fasteners can also be used. The effective length of the horizontal portion 277 of the purge tubes 261 is then adjusted by moving the inner tube 280, similar to a vehicle radio antenna. The inner tube 280b is moved until it ends approximately 3.2mm (one-eighth of an inch) (as close as possible without touching) the moving parts of the impeller 266. In larger pumps, the installer can make this adjustment by physically adhering their hands in suction line 268 or channel 278 and pushing inner tube 280 towards impeller 266. However, in smaller pumps, the installer may need to use angled needle nose pliers and a 3.2 mm piece check gauge (one eighth of an inch). Instead of providing the adjustable inner tube 280, the horizontal portion 277 of the purge tube Suction line 268 may first, however, have to be shortened to obtain a good connection. ? The construction and operation of the manifold 190 and related components will now be discussed with particular reference to FIGURES 21 and 22. The manifold 190 is approximately 8.6 m (twenty-eight feet) in length and thus extends approximately 4.9 m (sixteen feet). ) from the exit end of line 120. The floor of the collector 190 is approximately 0.3 m (1 ft) below the passage bottom 120. Line 120 and collector 190 share a common entry plate 284 through the which the fluid jet conveyor 144 injects the pressure of the transport fluid of the bag. A backwater area 290 is defined in the manifold 290 under the discharge conveyor 140 and towards the end plate 194 of the manifold. The suction line 230 sucks water from the backwater area 290 outwards through an opening in the end plate 294. Placed in the backwater area 290 and described in FIGURES 21 and 22 are the drain 300, the filling buoy 304 (which keeps the water in line 120 314 volts. All 110 volt AC power comes from an AC supply of four hundred and sixty volts 320, which is graduated down a transformer to an AC supply of one hundred and ten volts 324. CD control power twenty-four volts comes from the AC power supply of one hundred ten volts 324 and the twenty-four volt DC power supply 314. The two discharge conveyors 140, 144 are AC powered four hundred and sixty volts, three phase, and the two feed conveyors 152, 112 are fed by a hundred ten volts AC, of one phase. All power for the motors is switched using motor starters that use the twenty-four-volt DC control voltage to power their coils. A preferred nozzle (or nozzle assembly) 136 of the present invention is illustrated in isolation in FIGS. 26-28. Referring to those figures, nozzle assembly 136 is observed formed of four parts. One of these parts is an entry hose 340 that has a sanitary fitting type THREE LEAF CLOVER elastomeric nozzle 356 having a taper inner fluid contact surface 360 and a rear collar 364. And the fourth of those parts is a THREE BLADE TRIPLE 370 fastener. Referring to FIGURE 28, two attachments 244, 352 have grooves or splines. respective indentations 374, 378, which receive therein the circumferential molding flanges 382, 386, respectively on the anterior and posterior faces of the anterior collar 364. The fastener 370 encloses the accessories 364, 352 holding them together with the collar 364 sandwiched between them . The housing 390 defined by the two sleeves 340 and 348 has a lip 394 at its outer end which prevents the nozzle unit 356 from extending too far outward, and the lip 394 has a small opening (4.8 mm (3/16 inch)) 396 which defines the outlet opening of the nozzle assembly 136. The housing 390 can be molded and machined from stainless steel. The nozzle unit 356 can be made by molding or injection molding silicone or buna-n. This may have an inlet diameter of approximately 2.54 cm (one meet the requirements of 'mechanical resistance and corrosion resistance of the particular use. As shown in FIGURE 28, the elastomeric contact surface 360 is deformed by turbulence in the fluid flow 398 to minimize turbulent flow through the nozzle assembly 136. The elastomeric coating is similar to the skin of a given marine mammal that does not allow turbulence to feed back or accumulate on itself. Less turbulence in the nozzle 136 means that greater energy will be released to the bag 108 with the same driving force. The elastic coating is also automatically cleaned of difficult residues. In other words, as long as the pieces of the debris are not too sharp or too large, the elastomer will "give" sufficient dimensionality so that the piece can slide through the hole 396. In contrast, a hard coating nozzle would not "allow" the passage of large hard objects through it. The contact surface 360 of the nozzle unit 356 is tapered to gradually increase the at a high output speed of approximately 3.04 m per second (10 feet per second). In other words, the exit velocity of the fluid flow may be approximately ten times the entry speed and with an improved focus. As stated above, the system 100 can be used to efficiently heat products in flexible bags instead of cooling them. It can also be used to heat products in sealed flexible bags and then cool the hot product in the bags. The basic steps of a heating and cooling system are shown generally at 420 in FIGURE 30. Referring to this, the raw product 424 is filled into bags formed of bag material 428 in a forming / filling / sealing station 432. The filled and sealed bags 434 are then passed through a heating line 436 where the heating fluid ( water) is heated by a heat source 440, as will be discussed later in greater detail with the discussion of FIGURE 32. The hot bags are then released and passed through a A heating line as Example 436 is shown in simplified form in FIGURE 32. The collecting container 450 (similar to the manifold 190) is shown, but for illustrative purposes the perforated line (120) in the container is not shown. Neither is shown in this figure (but shown in other figures at the beginning) the two rows of heating jets, which would be placed on opposite sides of the line. In this way, the product filled and sealed bags (as will be described below) are transported by the feed conveyor 454 and deposited in the line in the collection container 450. The water in the container 450 is sucked into the outlet 458 in one end of vessel 450, through tube 464 by high pressure pumps 468. FIGURE 28 illustrates three different heat sources (440) for water. Although they are preferably alternative heat sources (i.e., only one would be used) it is within the scope of this invention to use two or more if desired. A heat source uses fire tubes, such as outward through the chimneys 480, 482. A second heat source (440) can be an electric immersion heater 480 placed to heat the water in the container 450. And a third heat source includes passing the tube 464 through of a heat exchanger 484 to heat the water flowing therethrough. The heat exchanger 484 may be a water tube boiler where hot flue gases are passed over the tube (or a plurality of tubes) within a furnace enclosure, thereby heating the water, and then the flue gases. Chimney are expelled out through a pile. The hot water in the tube 464 passes the two tubes 490 and 494 of the nozzle system and the fluid jet conveyor 498, similarly to the system provided in the (cooling) passages described at the beginning. The nozzles then direct the hot water against the bags providing the massage and rotation action as described above to efficiently heat the contents of the bag. And the jet conveyor 498 transports the bags as 444. Special precautions are taken in the design and operation of the heating line 436 to ensure that the operator thereof is not scalded by the boiling water. The transparent cover used for the cooling line can be replaced by a metal cover (opaque) for the variation of the heating line. The heating and cooling system 420 is a commercially important system because it allows the products to be sterilized and cooled in bags, which can then be packaged. This process is considerably cheaper and better for the environment than the current processes of using cans. In particular, it allows one to replace cans of 3,785 liters (one gallon) with 3,785 liters (one gallon) bags, which are transported in boxes (similar to wine bags in boxes). If relatively expensive fas and sealed sealed bags are eliminated, the bag system in a box here provides a very economical replacement for cans. The bags are made without filling fas 428 is bent over itself, sealed transversely along the bottom edge and sealed along the superposed longitudinal edges. Therefore a tube is formed which is closed at the lower edge and open at the top. Next, raw product (424) is poured through the open top. The upper part is sealed along an upper edge, and the material cut on top of the upper seal. And the process continues to form the next filled and sealed bag, and so on. This process allows the bag to be sealed before the product (424) is heated, which is advantageous because the seal can not be well controlled when the product is hot. More particularly and referring to the FIGURE 31, the plastic material 428 is unwound from a roll of film 504 on a collar (very similar to a shirt collar) and the flat raw material is automatically formed in an unsealed tube. As the tube moves vertically downward, it slides along a longitudinal sealing bar 508 which longitudinal). The transverse seals 516, 590 that cross the top and bottom of the bag are made with two retractable sealing jaws or bars 524, 528, with a retractable blade blade 532 therebetween. The transverse seal bar assembly on the vertical carriage 536 moves upwardly along the sealed tube when its jaws are open. At the top of the upward stroke (the length is determined by the length of the desired bag) the hot jaws 524, 528 close and begin to seal the bag. With the jaws still closed, the jaw assembly 536 moves downward to pull more bag material 428 from the roller 504 and over the collar and along the longitudinal sealing bar 508. When the transverse seal bar assembly is close to the lower end of its stroke, the blade of the blade 532 extends between two sealing rods 524, 528 to cut and separate the upper part of the first bag from the bottom of the second bag. The jaws 524, 528 are then opened, the first bag It drops into the neck of the collar and slides down towards the seal that was newly formed by the last clasp of the gag at the bottom of the new bag. This process works well for products at room temperature 424, but not for hot filling, since the heat of the product inside interferes with the sealing process. That is the reason why 'filling in cold and then heating and cooling according to this invention is a valuable invention. There is no scale limit for system 420.

This can be scaled down to process individual ketchup bags or scale up to process bags the size of large rail cars. Fluid dynamics would change, but systems would have to be designed for each product in any case. The heating line 436 would be very similar to the system 100 and would use the principles thereof, including the massage and rotation of the flexible bags in the heat transfer fluid. Of course, the main difference is that a fluid of they would be exposed to high boiling temperatures would have to be made of suitable materials. For example, the pressure manifold (128, 132), the suction lines (230) and the nozzles (13 ^) would be made of metal, such as stainless steel, instead of PVC. Also, the pickup rollers would need to compensate for the large thermal expansion of the plastic of the polypropylene conveyor belt. Sterilization in the 436 heating line raises the temperature of the product from room temperature to 90.55 to 93.33 degrees centigrade (one hundred ninety-five to two hundred degrees Fahrenheit), using only fluid at 97.77 degrees Celsius (Two hundred and eight degrees Fahrenheit). It takes time, probably ten or fifteen minutes to heat a bag of 208.17 liters (fifty-five gallons) 428. In contrast, the cooling line 444 takes the product from 93.33 to 48.88 degrees Celsius (two hundred degrees to one hundred and twenty degrees Fahrenheit), but uses water at 21 degrees Celsius (70 degrees Fahrenheit). In this way, cooling only takes five minutes. This The great difference between the time to heat and the time to cool can be easily understood from FIGURES 33 and 34. FIGURE 33 shows a situation in the cooling line 444 where there is a large difference in temperature between the product in the bag and the solution the container. This means that there is always a large motive force and therefore a large heat transfer through the film of the bag. By contrast, FIGURE-34 shows the situation in the heating line 436, where only a difference of -12 ° C (10 degrees Fahrenheit) is left between the temperatures of the product and the heating solution. Therefore, the driving force for heat transfer is much lower, and consequently the time to reach the desired temperature in the bag is about three times greater for heating than for cooling. To significantly raise the temperature of the heating solution is probably not economically practical. Thus, the heating line 436 will be approximately three times longer than the cooling line 444 in the system 420 if water is used at atmospheric conditions such as the heat transfer solution. The heating line 436 can be three heat transfer lines sized by the cooler (120) running end to end (in series) or in parallel to a cooling line running three times faster. In any case, the heating volume will be three times greater than the cooling volume. If the bags are running in series, there would be nine active stations on the 436 heating line. The system can also be designed so that there are fewer active stations with more time invested in each station, but then a single unit would probably be used. filling to combine parallel tubes in a row before entering cooling line 444. For a bag of 202.17 liters (fifty-five gallons) of cutter or chopped tomatoes, it would take approximately fifteen minutes to heat to a sterilization temperature of 90.5 at 93 ° C (one hundred ninety-five to two hundred degrees), starting at a temperature of 21 ° C (seventy degrees). Although the retention time at a sterilization temperature varies for each product and container, it will typically be eight minutes for a 52.17 gallon bag with a filling faucet when the bag is "hot filled" ( product heated in a heat exchanger and loaded in a cold bag and covered with a cold lid). With a filling tap that time can probably be reduced to four minutes. The reason for that reduction is that the filling faucet is a large piece of plastic and the plastic is a thermal insulator. Although the product probably only needs two minutes at the sterilization temperature to be sterilized and the bag probably needs the same, the filling faucet probably requires four minutes. Therefore, the system comprised of the product (heated in a heat exchanger and released to the bag) plus the bag plus the faucet requires eight minutes of retention after assembly .. Heating after assembly of the package allows the container to warm up in parallel with the heating of the product. In this way the retention time in a bag, with or without a filling tap, can probably be reduced to two minutes after leaving the heating section. It would be more practical to size the heating container so that the retention time is completed in the dead zone of the container. The biggest time saving is in the heating of the filling faucet (the longer time requirement) while the product is being heated. The total retention time in the heating line will probably be fifteen to eighteen minutes for a bag of fifty-five gallon tomatoes and most other food products. The material in the bag only needs to maintain a slight vapor pressure inside the bag in system 420. Using water as the heating fluid that is open to atmospheric pressure means that any boiling will occur in the water and not in the food product or another product. Since the heating source is the heating fluid and not the food product, the temperature will always be slightly higher in the container (120) than in the bag. Therefore, any tendencies to evaporation will be in the fluid and not in the food products. The bag only has to maintain a slightly higher than atmospheric pressure to prevent vapor displacement (boiling) inside the bag. A system, according to this invention, which uses a heating fluid with a boiling temperature higher than that of the contents of the bag requires careful verification that the bags do not explode.

On the other hand, a system using a heating fluid whose boiling point is equal to or less than that of the contents of the bag would be intrinsically safe. The heating fluid probably has a lower boiling point than that of the food product inside because the water is relatively pure compared to the contents of the bag. Pure water boils at a lower temperature than water that has salts (of food) dissolved in it. The lower the viscosity of the product 424 to be heated, the lower the power required to circulate the content. When the viscosity increases, the power provided to the bag should increase. The strength of the bag limits the amount of power that can be provided to the bag. A high water content of the product 424 is not required. Dry products can still be heated as long as they have a flowable fluid consistency. The product (424) is not limited to food products, such as tomatoes, chilies and peaches. The product, for example, can be certain medical products that need sterilization. Products that need heating to be "finished" can be processed in this system, such as a chemical reaction that can be heat catalyzed and that can not be conveniently bagged-after that reaction. Also, the 420 system would allow manufacturers, such as chemical manufacturers, to easily work with highly corrosive materials without using heat exchangers in expensive anti-corrosion piping systems by processing the materials in flexible bags. An alternative system 600 of the present invention is shown, for example, in FIGS. 35-37. This alternative system 600 can be adapted to cool (or heat) bagged or packaged products, as described above. For discussion purposes, the method or system where the bags are cooled will be described later. However, those skilled in the art could easily adapt the cooling system for heating. The main modification for heating is to use metal tubing for pressure lines (nozzle supply) instead of PVC (or any other piping system that is greatly decreased by temperature increases). The deflection valve also needs to be selected to resist heat. The heating can be effected in the same manner as described in the previous embodiments, namely, fire tubes, heat exchanger, steam lines, microwaves, and so on. Similarly, the cooling may be established in any of the previously discussed ways, such as by means of a cooling tower or a cooler.

Referring to FIGS. 35-37, a pair of high pressure cooling fluid (water) tubes 604, 608 are provided on opposite sides of the main line or transport tube of larger products 612. The cold water passing under high pressure in the cold water inlet pipes is then distributed or sprayed into the main channel 616 by a plurality of nozzles, as described above and shown in FIGS. 26-28 discussed above. Each section of the line 600 assembly, as described in FIGURE 1, is approximately 2.4 m (eight feet) and its surface sealing gasket 620 is 1 m (forty inches) high and 1.2 m ( forty-eight inches) wide. Eleven nozzles can be used for each section of pressure supply tube equally spaced throughout the length of the tube resulting in a total of twenty nozzles per section. Eight sections can be connected together making a total of one hundred sixty-six nozzles. The first and second nozzle assemblies of the first and second pressure supply tubes 604, 608 then induce a twisting or rotation of the flexible bagged product in the tube (closed passage) according to that shown by arrow 630. This not only produces a rotation of the bagged product but also a massage action, similar to that described in the embodiments described at the beginning of this invention. The cooling water after surrounding and cooling the products in the bags is then distributed outwardly through the fluid outlet tubes 640, 644. The outlet tubes or fluid suction lines 640, 644 may be tubes of fluid. 25.4 cm (ten inches) stainless steel. In contrast, the pressurized cold water inlet pipes can be PVC pipes of 15.2 (six inches). Referring to FIGURE 37, the fluid circuit or simplified pipe design is illustrated. It is observed there that first and second pressure pumps 650, 654 are used. For the first pressure pump 650 the bag 670 moves far to the right until its suction to that pump is completely interrupted, at which point it stops pump, since there is no fluid from the nozzles on the lower left. The second pump 654 therefore pumps harder because its suction is more open. The second pump 654 then creates a force to the left and sweeps the bag 670 out of the first suction pump, and the first pump 650 then resumes pumping. The bag 670 then moves far to the left and the second pump 654 stops pumping. Therefore, the first pump 650 is made to pump hard and the bag 670 is swept from the second suction pump. The second pump 654 resumes pumping and the operation is automatically restored. The resultant action of those first and second pumps 650, 654 is that the bag 670 slowly oscillates between the first and second sides, and the bag therefore never completely covers any suction of the side pump. A comparison of the design described at the beginning that has the perforated line sitting in the manifold and the alternative design currently described can be understood from a comparison of FIGURES 38a and 38b and the following discussion. FIGURE 38a generally shows the old design with the perforated container 674, an external tank 678 and the insulation 682, and the surface area 686 for the loss of heat to the environment, ie the external tank. In contrast, referring to FIGURE 38b, the insulation is shown at 690 and the surface area 694 for the loss of heat to the environment is that of the container. The alternative design is theoretically more efficient to induce internal circulation. And better internal circulation means faster cooling and therefore smaller and less expve machines. Also, better circulation allows the machines used to be extended to extremely viscous products, such as peanut butter and so on, without damaging the brittle bubbles. In other words, the container design of FIGURES 35-37 allows for more efficient machines, smaller machines, a "higher range of applications with the same bag strength, faster assembly and more reliable sealing in modular interfaces. In addition, the alternative design is less stive to the level of the cooling bottom than the design discussed at the beginning, which can operate within a range of a few inches to approximately a level of 4/5 full. Because the only escape for the cooling fluid (cold water) is through the suction lines 640, 644, the alternative design can operate between a level between just above the suction lines all the way to the top An additional advantage of the alternative design is that it is less stive to the fluid levels of the line making the operator's work easier. a more efficient final plate 702 for mounting to a power module 706 (or 600). The blind end plate 702 includes openings for the pressure line 710, 714 and openings for the suction line 718, 722, as well as the deflection or jet transport orifice 736. In addition the openings of the hole for the pin are illustrated. or screw 734. And blind end plate 702 is mounted on gasket 740. Gasket 740 is best shown in isolation to FIGURE 40. This can be made of an elastomer, such as Buna-n, Viton, Neoprene and so on. This would be used for high temperatures, as an example. The gasket 740 includes openings for the pressure line 748, 752, openings for the suction line 756, 760, opening for the path of the bag 764 and holes for screws or bolts 768. A further comparison of the action of rotation and cooling of the bag between the alternative designs and the previous designs is shown in FIGURES 41 and 42. FIGURE 42 shows the design described at the beginning. Referring to this, it is observed that the cooling water is allowed to escape from the surface of the bag in an upper zone 780 and in a lower zone 784. The non-lubricated zones 788, 792 on the opposite sides provide viscous friction to the high bag . The jets 800, 801 are illustrated, as well as the perforated container. The suction of the large tank or collector is difficult to isolate. In contrast, the alternative design is shown in simplified cross-section in FIGURE 41. This shows the transport tube, the first and second nozzle jets 604, 608 and the first and second suction tubes 640, 644. The bag 670 is shown and its rotation is shown by rotation arrow 630. Heat 812 is transferred through the bag. Advantageously, the cooling water 816 remains with the bag and lubricates for a better rotation of the bag. In this way, the alternative design has the advantage over the design described at the beginning of having a less exposed surface area per bag volume and therefore less gain / loss to the surroundings. This makes it easier to isolate, which is important and for the moment necessary when cold brine or very boiling water solutions are used. hot Only one sealing surface on the end plate 702 is necessary. In contrast, the above design may require internal and external container seals, if it is modular. The design of the cross-installation of the brazing tubes and the suction tubes creates a perfect axial centering of the bag 770 in the tube or passage. In addition, the reciprocating container, passage or non-perforated tube (600) allows improved lubrication of the bag and therefore faster rotation. This results in better internal circulation, faster heat transfer, smaller machines, lower costs and a firmer product.

For each 2.4 m (eight feet) section (see FIGURES 35-37) there are typically two rotation stations in it. There will be a minimum of two bags per section of 2.4 m (eight feet), or a maximum of three. Variable bag populations are possible since the bags 630 are flexible and not fully filled, and their diameters can be increased if they are compressed end to end. The diameter of the container is such that there is freedom of action for the bag 670 to increase its diameter and not to adhere to the walls. The maximum practical retention time per station is approximately 15 minutes. And the minimum is determined by the speed of the product. Theoretically, in very large machines, the retention time could be one second. However, as a practical aspect, the minimum retention time is approximately 15 seconds. Less than that, as' a practical aspect, may require parallel systems. 15 minutes multiplied by 40 rotations per minute in a maximum of 600 rotations. The practical minimum is 15 seconds multiplied by 40 rotations per minute to obtain ten minimum rotations per station. As described above with reference to Figure 37, two pumps, 650, 654 may be used. However, it is also within the scope of the invention to use a pump to exert traction from both the multiplied 640, 644 suction lines and the pump. distributes to both pressure manifolds. Although the single-pump system works, the preferred method is to use the two pumping systems because a natural centering action does not occur unless there is tension between the two opposing crossed systems. Centering results in faster rotations, which creates better internal circulation. The pumping hydraulics with the cross disposition is shown in FIGURE 43. It is observed there that according to one modality six (instead of two) pumps 820, 824, 828, 832, 836, 840 are provided, each unloading towards respective discharge lines 604, 608 and pumping the fluid obtained from the larger suction lines 640, 644 feeding from the line or transport tube. The left lateral suction 850, the discharge 854 on the right side, the right lateral suction 864 and the discharge 868 on the left side are shown in the lower right portion of the drawing. The suction of the output module 870 feeds the bypass pump 874, which pumps the transport fluid to the transport tube. Deviation 878 for 90 ° modules, if used, will be described in detail later.

The hydraulic scheme of FIGURE 43 is shown in FIGURE 44. Referring to it, the output module is shown at 890 and the 894 jets are shown oriented from below, if used. The 90 ° 900 right turn module is described in the upper portion of the drawing and the 90 ° 904 left turn module adjacent to it. The modules or sections of the container 600 are illustrated, as is the feed module 908. The feed to the feed module 908 are the multiple pumps 820, 824, 828 on one side and the pumps 832, 836, 840 on the other . Multiple pumps are provided for redundancy. The heat rejection systems are shown schematically 912 and 916. The blind manifold for additional expansion is shown at 920. The bypass pump 874 can take the place of the valve when the cycles are low and the high sites require valves due to that the interruption and starting of the pump motor would overheat the motor. Three methods of synchronizing the pumps can be used. The first method is to use the diversion pump 874 which is separate from the other pumps. This is good for low frequencies or multiple 90 ° turns. The jet pumps (for example 820, 83, etc.) are always "on" for this method. The diverter pump 874 or the main transport pump is on when it is time to advance the bags. The synchronization of this system is shown in FIGURE 45 generally at 930. One second, synchronization method uses a bypass valve which works in high frequency applications in a straight line. The timing is the same as in the first method except that the main transport fluid is derived from one or both of the pressure manifolds. The third method is used in a 90 ° turn. The external pressure manifold 934 is diverted to the outside so that the flow provides less installation. This is shown in FIGURE 46 where the diverter valve is shown at 938 and the flow of the bag is shown by arrow 942. The timing is the same as for the first method. The pump (for example, 650 or 828) can be 15 kW (twenty horsepower), a closed end of 9.1403 kg / cm2 (one hundred thirty-five PSIG), 8.4372 kg / cm2 (one hundred and twenty PSIG) at 62.45 m3 / h (two hundred and seventy five GPM), an open drip proof motor, centrifugal pumps with reconverted air purge systems.

Alternatively, pumps of 29.83 or 44.74 kW (forty or sixty horsepower) can be used for larger systems as long as at least a total of four pumps are used - two for the cross pipe and two for redundancy. That is, if a failure occurs, the system does not have to be interrupted. The number of modules of 2.4 meters (eight feet) (600) used depends on the weight of the bag and the viscosity of the product, the quality of the insulation, the bags used, the temperature of the product and so on. A typical size would be to use approximately 18.28 meters (sixty feet) in total including feeding. Therefore, approximately seven centered and one feeding modules can be used for approximately an active length of 19.50 meters (sixty-four feet) for a space of at least sixteen bags or a minimum of twenty-four bags. The total cooling system will look the same as those described at the beginning of this description except for the cross-installation design and, the orientation section, the. design of the container, the anti-injection filter that stops the particles generated by the self-destruct pump so that they are not injected into the bags by the nozzles. The electrical diagram will preferably have an isolation transformer to eliminate grounding problems in the plant.

The diverting valve will preferably be a balloon valve to provide more positive interruption and better flow direction than a throttle valve. FIGURES 47 and 48 show the straight flow pattern downstream of the balloon valve 944 and the edged shaft flow of a butterfly valve 948, respectively. Additionally, the collection valves on the cavitation elimination system on the pumps will preferably be diaphragm check valves, instead of balloon check valves, for a lighter forward pressure opening and a more positive closure. The input module would be the same as a regular 2.4 meter (eight foot) module 600 with a feed hopper bolted on top and a larger access hole to release the bag. Also, the installation or connection manifold would have connections attached to a blind end plate (blind to the bag but not to the suction and discharge lines). The side and end views of the feed hopper 972 are shown in Figures 49 and 50 with the side surface shown at 956 and the bag shown 960. A top view of the hopper is shown in FIGURE 51 with the flow of bags of 966 feed extending up in the drawing.

An important function of the output modules is the orientation of the bag. There are two preferred ways of doing this according to the invention. Referring to FIGURE 52, the bag 970 is forced through an elliptical opening 974 and is made to rest on its edge 978. More particularly, the random orientation about the axis is shown at 982 inside the round container 974. The edge it is placed on one side of the conveyor 990 and the bag positioned according to that shown by the arrow 994, and the bag is centered on the conveyor 998 after it rolls on it. The second method is best shown in FIGURE 53. Referring to this, "the random orientation around this axis is shown at 1000. And the jets 1004 that strike the center of the shaft cause the bag 1008 to be oriented with its horizontal seams The oriented bag 1012 is centered on the output conveyor 1016. An example of the 90 ° section described above is shown in FIGURE 54 at 1100. Referring to this, the straight suction manifold is shown at 1120. The jet of deviation, which is in line with the output axis is shown at 1108 and the left suction manifold is shown at 1112 with the left pressure manifold and the right pressure manifold shown at 1112, 1004, respectively. The access doors 1124 are shown in the upper part of the product transport tube 1130. This section 900 is for turning at the corners while transporting the container continues. The deflection jet 1108 is connected in parallel with the deviation in the feed. In this way when the signal is given for the bags to advance, the bags are helped or assisted around the corners. The turning sections on the right and left can be used with modules of the container to form any configuration and can be combined two to form a 180 ° turn (as shown in FIGURE 44, for example). A variation of this alternative container design is to use the same concept except that larger and smaller holes are used in the suction manifold. Alternatively, numerous smaller and larger holes can be used in the suction manifold. Although three or four suction manifolds may be used instead of two, a suction manifold is not preferred because this would allow full coverage by a weak bag. An occlusion by complete suction by a bag would create an interruption of the system, requiring the intervention of the operator to remedy it. In other words, the suction system requires that a bag never completely cover the system. A preferred design is one that establishes a tension for the bag on opposite points to cover. In this way the bag always oscillates between the two states, never completely obstructing any suction orifice. The bag remains axially centered because it prefers to reside in the central region of low speed. This preferred geometry creates an axial region where the bag experiences the lowest velocity of the jets. If the bag can cover a suction line completely, then it slows down the speed of the jet by obstructing the suction, creating its own lower velocity region and obstructing the suction even more until the flow drops to zero. And this is satisfied (now the system is interrupted). The way to create a balance is to establish the geometry so that if the bag obstructs a suction line, it releases another. Releasing the other and each jet discharges before the suction line usually on opposite sides. Opposite to the container, the flow of the jet over the blocked suction line creates a countercurrent action that pushes the bag out of the blocked suction area. FIGURE 55 shows in a general manner at 200 the different temperatures between the feed and outlet nozzles. Product temperatures can be observed there. The product temperature drops asymptotically to the cooling tower temperature of 18 ° C (65 ° F) (or 17 ° C (45 ° F) if cooler water is used). The temperature of the suction water increases in a straight line from 24 ° C to 29 ° C (75 ° F to 85 ° F), moving from the discharge end to the feed end. As can be seen the temperature of the transport water that remains stable at 24 ° C (75 ° F) and the temperature of the jet water remains constant at 21 ° C (70 °). The cooling tower remains constant at 18 ° C (65 ° F) or 7 ° C (45 ° F) if a cooler is used. From the above detailed description, it will be evident that there are numerous changes, adaptations and modifications of the present invention, which fall within the experience of those skilled in the art. For example, certain features of this invention can be used to heat or cool the contents of rigid containers (as opposed to flexible ones). However, it is intended that all those variations that do not deviate from the spirit of the invention are considered within the scope thereof. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.

SUMMARY OF THE INVENTION A construction of a heat transfer line or tunnel that includes a line (120) along which water is propelled to transport a bagged product (108) therealong. A plurality of nozzles (136) spray jets of cooling or heating water on the product (108) when it is transported along the line or tunnel (120). The nozzles (136) are oriented in first and second opposed series to impart a rotation of bagged product (108) generally about a longitudinal axis of the line or tunnel (120). According to one embodiment, a first suction tube (230) having openings through the wall of the line or tunnel (120) is opposite to the first series of nozzles (136) and with a first pump (236) forms a first fluid circuit. Similarly, a second suction tube (264) with suction openings, together with a second pump (258) and the second series of nozzles (136) forms a second fluid circuit. The two fluid circuits keep the bags (108) centered in the line or tunnel (120), surrounded by cooling water or - heating. According to a second embodiment, the line or tunnel (120) is placed in a collector (190) and has openings therethrough, so that the water in the line or tunnel (120) communicates with that of the collector, and the suction tubes (230, 264) are not used.
