Description

Food processing equipment

The present invention relates to a food processing apparatus that performs processing such as cleaning, heating processing, cooling processing, and thawing processing of an object to be processed, and conveyance.

Conventionally, as an apparatus for washing food, for example, an apparatus having a form as shown in Patent Document 1 below can be cited. This accommodates the treatment tank with the upper surface opened in the water tank with the upper surface opened, and supports the treatment tank within the water tank. Thereafter, a drive device is provided that lifts the treatment basket to the outside of the water tank and rotates the treatment basket so that the open surface of the treatment basket is inclined in one direction. In this apparatus, an air blowing device is provided at the bottom of the water tank, and air is blown out from this device so that the food in the treatment basket is washed, and the excluding substances adhering to the food can be separated.

However, in the device shown in Patent Document 1, most of the exceptions separated by using the above-described air ejection device are discharged outside from the buttocks, but some garbage comes into contact with food again. For this reason, there is a possibility that the exclusion product and the food adhere to each other and the cleaning becomes insufficient.

On the other hand, an apparatus shown in the following Patent Document 2 has been proposed. The configuration is as follows. A chute is provided at one side edge of the treatment tank, a side edge opening is provided at the other side edge, and a water delivery device is provided at a predetermined position of the water tank. A step portion is provided at the bottom of the treatment tank, and the step surface of the step portion is arranged so as to face the direction of receiving the water flow generated by the water delivery device. Further, a fulcrum pin serving as a center of rotation when the processing rod is tilted and rotated is provided, and a support plate is projected at a position higher than the fulcrum pin. A rotating arm with one end fixed to the drive unit is placed along both end faces of the processing rod, and a fulcrum pin is pivotally connected to the support part near the tip, and the upper and lower parts are connected between the arm tip part and the support plate. By providing the required spacing in the direction, the exclusion can be efficiently separated from the food.

In addition to these, there is also a method for washing food by spraying a water stream from an injection nozzle.

Japanese Patent Laid-Open No. 11-266800 JP 2009-11268 A

However, the water delivery device shown in Patent Document 2 is a screw type and is provided alone at the center of one side wall of the water tank. Since the rotating water flow generated from this water delivery device is inevitably biased in the vertical and horizontal directions, if there is too much food to be cleaned, the cleaning does not proceed uniformly and the cleaning effect may be biased. If two screw-type water delivery devices are mounted side by side and are driven so as to rotate in the opposite directions, the water flow in the entire aquarium circulates symmetrically, so that there is no bias, so this problem is solved. However, if two water delivery devices are provided, the facilities become complicated, and it takes time for maintenance after use, and the time required for food processing operations increases substantially. Moreover, since the installation cost and the running cost are extra, the cost has been significantly increased compared to a food processing apparatus having a single water delivery device.

Furthermore, in the configuration using the injection nozzle in the water delivery device, the piping structure becomes complicated if it is attempted to circulate while suppressing the consumption of water. For this reason, dust, oils and fats contained in the water to be circulated easily block the nozzle, and sometimes stick to the inside of the pipe, causing a problem in maintenance.

Therefore, an object of the present invention is to eliminate uneven treatment due to water flow with a structure that can be easily maintained after use without increasing the number of mounted drive units.

In the present invention, a treatment tank having an open upper surface is accommodated in a water tank having an open upper surface, the treatment tank is supported in the water tank, and is lifted to the outside of the water tank so that the open surface of the treatment tank is In a food processing apparatus provided with a drive device that rotates to incline in one direction,
Having an external water tank in contact with the water tank,
The partition wall separating the water tank and the external water tank can pass the water flow from the external water tank at a position below the water level of the water tank at the time of food processing and above half the deepest depth of the water tank. The first water flow passage is provided,
In the treatment tank, a second water flow passage port capable of introducing a water flow from the first water flow passage port is provided at a position facing the first water flow passage port when stored in the water tank, and , Water can enter and exit the inside and outside of this treatment tank,
In the outer water tank, a rotating water turbine for generating the water flow is disposed in a horizontal direction along the partition wall, and the upward water flow generated by the rotating water turbine is rectified to the first water flow passage opening. The problem is solved by arranging the rectifying unit to be placed on the rotating turbine.

The food processing apparatus according to the present invention introduces the water flow in the tangential direction generated by the rotating water turbine into the water tank by narrowing the direction by the rectifying unit. For this reason, it is not necessary to use a propeller type in which the agitating blade is twisted as a rotary turbine, and the shape of the agitating blade (runner) can be made uniform in the axial direction so that the generated water flow is not biased. Moreover, since the force which the stirring blade of a rotary water turbine rotates can be made into a water flow as it is, a strong water flow can be generated. Moreover, if the covered rectifying unit is removed, both the rectifying unit and the rotating water turbine can be easily cleaned, and therefore maintainability is higher than a piping structure that is easily closed.

The configuration of the rectifying unit includes, for example, the following forms. A rear plate covering the partition wall side of the rotary turbine, a front plate covering the opposite side, a cross-section arcuate portion extending from the upper side of the front plate to the back plate side by a curved surface having a cross-section arc shape, and the rotary turbine It has a throttle part covering the upper part on the back plate side, and a slit-shaped air outlet formed at the tip of the arcuate section and the throttle part. As a result, the direction of the upward water flow can be changed efficiently, and the first water flow passage port can be passed through the outlet and sent to the treatment tank. Moreover, if it is this shape, the said rectification | straightening part can be mounted | worn only by covering the said rotary turbine from the top.

In the above rotary turbine, it is preferable that arc-shaped blades serving as stirring blades have a sufficient length in the axial direction facing the horizontal direction so as not to bias the water flow as much as possible, and are approximately equal to the length between the side walls of the water tank. It should be about the length. In addition, in order to supply the water flow generated by the rotating water turbine to the treatment tank in the water tank without being biased as much as possible, the rectification unit that rectifies the water flow, the first water flow passage port through which the rectified water flow passes, and the above It is preferable that any of the second water flow passage openings has a horizontal length substantially equal to the horizontal length of the stirring blade of the rotary turbine. For this reason, the shape of these mouths is preferably a horizontally long slit so that the entire area can be covered while maintaining the momentum of the water flow.

In the above rotary turbine, a shaft portion not provided with runners near both ends is placed on a sliding bearing, the rotary turbine is fixed so as not to be displaced in the axial direction, and water is supplied between the receiving tool and the holding tool. The shaft can slide as a lubricant so that it can rotate freely.

It is desirable that the water sent from the rotary turbine flows into the rotary turbine from many directions other than the direction from which the rectifying unit delivers. Specifically, there are axial ends, a front-rear direction with respect to the water tank, and a lower side, and it is particularly preferable to flow in from all these directions. If the inflow of water is only from both ends in the axial direction, the water may not reach the central portion in the axial direction, and the water flow may be biased. If the water that has entered the rectifying unit from below or before and after is directed upward by the rotational movement of the rotary turbine, the water flow is less likely to be obstructed and the water pressure is easily maintained. In addition, since water is supplied over the entire axial direction of the rotary turbine, even when the first water flow passage opening and the second water flow passage opening are widened as much as possible in the horizontal direction, the water is stable over the entire area. Water can be fed into the

As a configuration for supplying water from the lower side of the rotating water turbine as described above, for example, a water gap is arranged between the bottom surface of the outer water tank and the lowermost end of the rotating water turbine, and water falls into the gap. The structure which enables supply by sucking up water to the rotary turbine is mentioned. It is preferable that the space from the gap to the side rotating upward of the rotary turbine is open because water is efficiently supplied to the rotary turbine. Also, in this case, instead of opening the entire lower surface of the rotating turbine, a lower plate is provided between the bottom surface and the rotating turbine and only the portion that takes in the upward water flow is cut out, so that the downward water flow is further reduced. The waste that occurs can be suppressed.

In addition, as a configuration for supplying water from before and after the rotary turbine, a water inlet is provided in the rectifying unit. If the lower side of the shaft height of the rotary turbine is opened and can flow from the periphery toward the rotary turbine, water can be supplied efficiently.

The rotary turbine is mounted on a fixed bearing having a height such that the gap is formed with the bottom surface of the outer water tank. A sliding surface is assumed. By such a form, the said rotary water turbine can be removed with the said rectification | straightening part, and the said outer water tank can be wash | cleaned easily and can be maintained. In addition, the sliding bearing is fixed on the lower plate, and a fixing hole is formed in the lower plate, and the fixing hole can be installed from above so that the protruding hole protrudes upward from the fixing base. If it does so, it can remove to the said lower board after use, and can wash | clean to the bottom face of the said outer water tank easily after use, preventing the shift | offset | difference to the front-back left-right direction with the said fixing hole and an overhang | hanging pile.

Furthermore, as a form in which water is supplied from both axial ends of the rotary turbine, a part of the rectifying unit in the axial direction is opened.

It is desirable that the rotating water turbine is installed at a position higher than the bottom of the treatment tank and the water tank and close to the water surface. If the distance from the rotating water turbine to the first water flow passage port is too long, the momentum of the water flow is easily attenuated. In addition, the rectifying unit that receives the upward water flow is bent along the circular arc when the upward water flow is directed to the first water flow passage port in the horizontal direction by the curved surface portion having an arcuate cross section. Attenuation is minimized.

The water supplied to the rotating water turbine is not only supplied from the outside, but may be circulated throughout the food processing apparatus by receiving the water overflowing from the treatment tank in the outer water tank. When the rotary turbine is operated, a pressure difference is generated, and the water level in the treatment tank and the water tank to which water is supplied becomes higher than the water level in the outer water tank. For this reason, water is returned from the heel to the outer water tank at a height that allows sufficient cleaning in the treatment tub.

The capacity of the outer water tank needs to be sufficient to supply water to the rotating water turbine even when water is sucked into the water tank due to a water pressure difference when the rotating water turbine is driven and the water level of the outer water tank decreases. is there. For this reason, if the depth to the bottom surface of the outer water tank is shallow and the position of the rotating water turbine is too high, there is a risk of hindering water supply. Moreover, even if the volume of the outer water tank is too small, there is a possibility that the supply of water is similarly hindered.

On the other hand, it is preferable to provide a net part for filtering out the exclusion object under the jar overflowing with water from the treatment basin so that the water passing through the net part falls to the water intake side of the rotary turbine. . With the progress of the circulation flow of the entire food processing apparatus, the exclusions generated in the entire apparatus can be collected together at the net. The net part is hooked on the edge of the wall of the outer water tank and the edge of the partition wall, and the net part is preferably developed between them.

As a mechanism for rotating the rotating turbine, a passive disk having a permanent magnet attached to the surface facing the wall surface is attached to one end portion in the axial direction of the rotating turbine toward the wall surface of the outer water tank. A slight gap is provided between the passive disk and the wall surface of the outer water tank, and no hole is formed in the wall surface of the outer water tank. In addition, a motor is attached to the outside of the outer water tank that faces the passive disk across the outer wall of the outer water tank, and an operating disk with a permanent magnet attached to the surface facing the wall surface is also rotated by this motor. Attach to. This operating disk is also provided at a position where a slight gap is provided between the outside and the wall surface, and facing the passive disk with the outer wall interposed therebetween. That is, although the working disk and the passive disk attract each other, they are attached so as to be freely rotatable on the spot so as not to approach the other party beyond the wall. When the operating disk is rotated by a motor, the passive disk is rotated by the magnetic force between permanent magnets, and the rotating water wheel itself can be rotated to generate a water flow by rotating the passive disk. In particular, since the mechanical mechanism is simple, it is easy to clean, and since there is no hole in the wall surface, it is easy to maintain water tightness.

When the treatment is completed, the rotation of the rotary turbine is once stopped, and then the treatment tank is lifted. This is because if the treatment tank is lifted and the second water flow passage opening is shifted, the water flow may hit the wall surface of the treatment basket and scatter. The processing object is moved to the next step from the processing tank, and the rotating water turbine is moved again after storing the processing tank in the water tank.

This food processing apparatus can be used alone or in combination with a plurality of units. When connecting, you may arrange | position so that the destination which rotates the said processing rod of one food processing apparatus, and discharges | emits a process target object is the processing rod of another food processing apparatus. In this case, it is advisable to connect the water tanks between the adjacent food processing apparatuses or between the food processing apparatuses that are separated from each other by a water channel so that the water channel can be closed by a shutter or the like. As a result, when performing multi-stage processing with a plurality of connected food processing apparatuses, new water is supplied to the final processing side (upstream side) water tank or the external water tank to perform final cleaning and final processing. Improve the quality of the finish. Then, when the rotary turbine is stopped at the time when the treatment with one unit is finished, there is no pressure difference between the water tank and the outer water tank, the water level is averaged, and the water level of the outer water tank is raised. At this timing, when the shutter of the water channel leading to the food processing apparatus on the earlier processing side (the downstream side as the flow of water) is opened, water flows into the outer water tank of the food processing apparatus on the downstream side. At this time, if the rotary water turbine of the downstream food processing apparatus is in operation, the water level of the outer water tank on the downstream side is lowered, so that water can be easily transferred. When the water is sufficiently transferred to the outer water tank of the food processing apparatus on the downstream side, the shutter is closed. If there is a further downstream food processing apparatus that receives new water from the upstream side, the rotating water turbine is similarly stopped at the stage where the processing at that stage is completed, and the outer water tank After opening the water level, the shutter connected to the downstream food processing apparatus is opened. By repeating this, it is possible to maintain the purity of the water used in the processing of a series of apparatuses while reusing water from the upstream side to the downstream side.

In addition, when connecting the external water tank of the said multiple food processing apparatus with the said water channel, the said external water tank has sufficient length in the direction which connects the said processing troughs so that it may be easy to connect with the said water channel. It is good to have. Specifically, it is preferable that the outer water tank surrounds not only the part where the rotating water turbine is provided, but also one or both of both side surfaces of the water tank.

Furthermore, when using a plurality of food processing apparatuses, the water channel may be connected by another connection method. Specifically, among a series of three or more food processing devices that perform processing continuously, by connecting one or more food processing devices separated from each other by a bypass water channel, The food processing apparatus in the middle of being isolated without being connected to the water channel can perform treatment with an aqueous solution different from the preceding and subsequent food processing apparatuses. For example, among three food processing devices that are continuously arranged so that they can be sent to the next food processing device after processing, when performing rough cleaning at the first stage, sterilization at the second stage, and rinsing at the third stage, The water after rinsing in the third stage is sent to the first stage for rough cleaning through the bypass channel, and in the second stage, treatment liquids such as hypochlorous acid water and hot water are used independently. be able to.

Since a wide flow of water is sent by the rotating water turbine, there is no bias in the flow generated in the treatment tank, and the food to be treated can be processed and washed evenly. Further, since the rectifying unit and the rotary turbine are removable, maintenance such as cleaning is easy.

Examples of processing that can be performed by the food processing apparatus according to the present invention include, for example, seasoning with a chemical solution, boil processing with high-temperature water, and sterilization processing in addition to washing food. Even in these treatments, unevenness in the finish of the processed food is less likely to occur due to the water flow in which the bias is similarly eliminated. Moreover, the cooling process by cold water and the thawing | decompression process can also be performed.

Embodiments of the present invention will be described below with reference to the drawings.
A food processing apparatus 11 according to an embodiment of the present invention is shown in a side sectional view of FIG. 1, a plan view of FIG. 2, and a front sectional view of FIG. The treatment basket 12 with the upper surface opened is housed and supported in a water tank 13 with the upper surface opened. Moreover, it has the drive device 20 which lifts this processing trough 12 to the exterior of the water tank 13, and rotates so that the open surface of this processing trough 12 may incline in one direction, ie, incline and rotate.

The treatment basket 12 is a bowl for putting a processing object 31 made of various foods, processed foods, etc. into a washing, heating treatment or sterilization treatment. Like the bottom surface mesh part 47, the processing rod 12 has a bottom surface formed in a mesh shape or has a large number of holes (see FIG. 2). Thereby, at the time of a process, not only the inside and outside of this treatment tank 12 can go in and out of water, but also the water can be drained by pulling up from the water tank 13 after the process.

The chute 12 is provided with a chute 41 on the end edge 40 on the lower side when it is inclined. The tip of the chute 41 is narrowed as shown in FIG. This chute 41 makes it easy to move the processing object 31 in the processing basket 12 to the next process such as the next adjacent food processing apparatus 11. The width of the chute 41 on the side of the processing rod 12 may be such that the processing object 31 does not spill outside when the processing rod 12 is tilted and the processing object 31 in the processing rod 12 is moved. As shown, the length of the end edge 40 is preferably equal to the width of the chute 41. Moreover, the length from the edge 40 which is a base part of the chute 41 with the processing rod 12 to the tip of the chute 41 needs to be a length that can sufficiently send the processing object 31 to the outside of the processing rod 12. When a plurality of food processing apparatuses 11 are connected, it is preferable to have a length that can be sent to the next process such as the adjacent food processing apparatus 11.

The fulcrum pin 43 serving as the rotation center at the time of tilt rotation is provided on the processing rod 12 at a position where the weight balance can be achieved on the outside of both side surfaces of the processing rod 12. By supporting the two fulcrum pins 43, the treatment rod 12 can maintain a state in which its open surface is directed upward. Further, support plates 44 project outwardly at positions higher than the fulcrum pins 43 on both side surfaces of the treatment rod 12. As will be described later, the support plate 44 is used when the treatment basket 12 is inclined. It is sufficient that the support plate 44 is provided only in the vicinity of the position where the fulcrum pins 43 are provided on both end surfaces of the treatment rod 12.

The drive device 20 for rotating the processing rod 12 has the following configuration. A cylinder 25 such as a hydraulic cylinder is connected to the rotary hook 24, and the rotary shaft 21 is rotated by pressing the rotary hook 24. The rotation shaft 21 can be rotated with respect to a bearing 22 fixed to the water tank 13 or the outer water tank 14. A rotating arm 26 is attached in the vicinity of both ends of the rotating shaft 21. One rotating arm 26 is provided on each side of the water tank 13 and the outer water tank 14. The base of each rotary arm 26 is fixed to the rotary shaft 21. On the other hand, a concave support portion 27 is provided in the vicinity of the distal end portion of the rotation arm 26, and the fulcrum pin 43 is rotatably supported by the support portion 27. Further, the rotating arm 26 is not linear, but has an arm bent portion 28 in which the arm is bent in the middle. Further, the pivot arm 26 has an arm tip 29 that extends further beyond the support 27.

In the embodiment shown in FIG. 1, the support portion 27 is a long hole cut obliquely from the upper end side near the tip of the rotating arm 26. Thereby, it becomes easy to insert the fulcrum pin 43 into the rotation arm 26. If the rotating arm 26 is rotatable with respect to the fulcrum pin 43, only a hole that can accommodate only the fulcrum pin 43 and is not connected to the outside may be provided. However, in that case, it becomes difficult to remove the processing rod 12 and perform maintenance. Although not shown, when a long hole cut from the outside is provided, a circular round shape having a radius of curvature larger than the diameter in the middle of the long hole can be provided in the vicinity of the cut inside the cut portion. By doing so, it is possible to prevent the fulcrum pin 43 from being detached from the rotating arm 26 when the processing rod 12 is tilted.

On the surface opposite to the chute 41 of the treatment rod 12 (the surface of the introduction side edge 49), a rotating turbine described later is located at a position close to a standard water surface height A when the rotating turbine 73 described later is not operating. A second water flow passage opening 42 for introducing a water flow generated from 73 is opened. The second water flow passage port 42 is slit-shaped, has a horizontal length close to both side walls of the treatment basket 12, and is preferably slightly larger than the outlet 95 of the rectifying unit 74 described later.

Further, the treatment rod 12 is provided with a curved surface portion 48 having a circular arc section from the bottom mesh portion 47 toward the chute 41. After the processing on the processing object 31 is finished, the processing object 31 can be efficiently dropped toward the chute 41 and the water flow introduced from the second water flow passage port 42 is efficiently directed toward the bottom. By being bent in the direction, the effect of efficiently circulating the processing object 31 in the processing rod 12 is exhibited.

A drain port 52 is provided at the bottom of the water tank 13. Although the valve is closed during use, drainage is possible by opening the valve as appropriate after use or when replacing water. Although not shown in the figure, an upper drain outlet is separately provided at a position higher than the standard water level A of the outer water tank 14 to be described later so that when the water is appropriately supplied and exceeds the standard water level A, the overflowed water can be discharged. It may be provided.

The water tank 13 that accommodates the treatment tank 12 needs to have a shape that can store the treatment tank 12. In the embodiment of FIGS. 1 to 3, the water tank 13 has a semi-cylindrical shape, and the treatment tank 12 has a shape along the inner wall of the water tank 13.

Moreover, the outer water tank 14 which contacts the water tank 13 is provided so that three directions except the side with the chute 41 of the treatment tank 12 may be enclosed among the outer periphery of the water tank 13. The outer water tank 14 is for collecting the water overflowing from the treatment tank 12 and sending it to a rotating water turbine 73 described later.

Similarly, the partition wall 56 between the water tank 13 and the outer water tank 14 located on the opposite side of the chute 41 is a slit shape that allows a water flow to pass to a position corresponding to the second water flow passage opening 42 of the treatment tank 12. The first water flow passage port 55 is provided. The blower outlet 95 of the rectification | straightening part 74 mentioned later is inserted here. The position of the first water flow passage port 55 may be a position below the water level B of the water tank 13 at the time of food processing (at the time of rotation of the rotating water wheel 73) and above half the deepest depth of the water tank 13, It is desirable to be close to the water surface. This is because in order to appropriately treat the processing object 31 having a lighter specific gravity than water, it is required to cause a strong water flow near the water surface.

On the introduction side edge 49 opposite to the chute 41 of the treatment tank 12, there is provided a front wall 45 for dropping water overflowing from the treatment tank 12 into the outer water tank 14. The front bowl 45 rides on a front edge 53 that is the upper end of the partition wall 56 that partitions the water tank 13 and the outer water tank 14. Further, at the upper end edges of both side surfaces of the treatment tank 12, the

side walls

46, 46 that drop the water overflowing from the treatment tank 12 toward the both side surfaces of the outer water tank 14 closer to the front wall 45 than the support plate 44. Is provided. The

side walls

46, 46 are on the

side edge portions

54, 54 that are the upper ends of the side partition walls 57, which are side walls between the water tank 13 and the outer water tank 14.

The outer water tank 14 surrounds the water tank 13 from three sides of the side buffers 62 and 62 that wrap around along the side partition wall 57 of the water tank 13 and the water turbine region 63 along the partition wall 56 with the water tank 13. Among these, a rotating water turbine 73 that generates a water flow in a water wheel region 63 in contact with the partition wall 56 and a rectifying unit 74 that directs the generated water flow toward the first water flow passage port 55 and the second water flow passage port 42 are provided. It is provided. The form of this rotary water turbine 73 and the rectification | straightening part 74 and its installation location is shown in FIG.

First, fixing

bases

71 and 71 for raising the ground contact surface of the rotary turbine 73 from the bottom are provided in the vicinity of both ends of the turbine region 63. With this fixing base 71, the rotary water turbine 73 is disposed with a gap between the bottom surface of the water turbine region 63. Through this gap, water flows from the bottom over the entire axial direction of the rotary turbine 73. Each fixed base 71 is provided with overhanging

piles

75, 75 protruding upward.

A lower plate 72 is provided so as to pass between the fixed

bases

71, 71. Fixing holes 76 are provided in the vicinity of both ends of the lower plate 72, and the lower plate 72 is fixed by inserting the overhang piles 75 of the fixing table 71 into the fixing holes 76. Sliding bearings 77 are provided at both ends of the lower plate 72 upward. This is composed of a semi-cylindrical receiving portion and a fixing column upward, and is received with the rotating shaft 83 of the rotating water wheel 73 interposed therebetween.

Further, below the partition wall 56 side of the lower plate 72, a lower rectifying plate 78 is provided that extends toward the bottom surface of the outer water tank 14 over substantially the same length as the axial length of the rotary water turbine 73. When the lower flow straightening plate 78 is present, water does not flow downward from the partition wall 56 to the rotating water turbine 73. At the same time, the water flow generated by the rotating water turbine 73 does not flow into the partition wall 56 side from below. Accordingly, water can easily flow into the rotary turbine 73 from the front water intake port 100 of the rectifying unit 74, which will be described later, and the momentum of the generated water flow can be stabilized.

Furthermore, the lower plate 72 is formed with a lower plate blanking portion 79 which is thinned on the side far from the partition wall 56. More specifically, it is desirable that the side farther from the axis center of the rotating shaft 83 received by the sliding bearing 77 is thinned, and the plate is left on the side closer to the axis center. The remaining plate suppresses the occurrence of a downward water flow due to the rotation of the rotary turbine 73, and rotates upward of the rotary turbine 73 from the gap below the fixed base 71 through the lower plate blanking portion 79. Water flows into the side, and the water flow can be generated efficiently.

The rotary water turbine 73 has a rotation shaft 83 that is at least longer than the horizontal length of the first water flow passage port 55, and has a runner (agitating blade) that generates a water flow along the rotation shaft 83. In the embodiment shown in FIG. 4, the rotating shaft 83 has an annular portion 81 that extends in the radial direction in the vicinity of both ends. The annular portion 81 is connected to the rotating shaft 83 by a plurality of arm portions 84, and a gap is formed between the rotating shaft 83 and the annular portion 81 in a portion where the arm portion 84 is not provided. Is formed. A plurality of arcuate blades 82 having an arcuate cross section perpendicular to the axis and extending to another annular portion 81 are provided on the axial surface of the annular portion 81 in the circumferential direction. This is the runner. The arcuate blades 82 are also not in direct contact with the rotating shaft 83 and are formed so as to create a gap with the rotating shaft 83. Further, the concave surface of the arcuate blade 82 having an arcuate cross section faces the rotational direction of the rotary water turbine 73 and is arranged so that water can be efficiently received and sent out. That is, when the arcuate blades 82 turn upward, the concave side surface is arranged to face the treatment basket 12.

The annular portion 81 may be provided not only at both ends but also in the axial direction. By providing the annular portion 81 in the middle of the axial direction, the stability of the arcuate blade 82 is increased. However, since the momentum of the water flow is reduced even if there are too many annular portions 81, the number of annular portions 81 other than both ends may be one or two.

Further, the form of the runner is not particularly limited as long as it can efficiently generate a water flow. For example, unlike the illustrated embodiment, the runner may extend radially from the rotating shaft 83 without generating a gap. If it is this form, it will be easy to make the rotational force of the rotating shaft 83 into a water flow.

The rotary shaft 83 penetrating the rotary water turbine 73 has a sliding surface 86 sandwiched between

flanges

85 and 85 provided with a width that can sandwich the sliding bearing 77 in the axial direction in the vicinity of both ends. This sliding surface 86 is in contact with the sliding bearing 77 described above. In addition, a passive disk 87 is provided at one end of the rotating shaft 83 and incorporates a permanent magnet and is driven to rotate by an external magnetic force.

A rectifying unit 74 that controls the direction of the water flow generated by the rotating water turbine 73 is placed from above the rotating water wheel 73. The rectifying unit 74 includes a front plate 92 that covers the partition wall 56 side, and a back plate 91 that covers the outer wall 65 side of the rotary water turbine 73. Above the back plate 91, a cross-section arc-shaped portion 93 having an arc-shaped cross section in the axial direction is bent toward the front plate 92. On the other hand, the front plate 92 is perforated as a front water intake 100 in the lower half or more as described later. Further, the upper portion of the front plate 92 is bent toward the back plate 91 and further folded back toward the partition wall 56 so that a constricted portion 94 is formed between the front plate 92 and the back plate 91. This throttle portion 94 covers half of the upper part of the rotary turbine 73 on the partition wall 56 side. The curved surface of the throttle portion 94 has a shape that does not collide with the rotating water turbine 73 and is preferably as close as possible to the outer periphery of the rotating water turbine 73 in terms of water flow efficiency. The tip of the throttle portion 94 is aligned in the same direction as the tip of the arcuate section 93, and a horizontal slit-like air outlet 95 is formed between them. The air outlet 95 is inserted into the first water flow passage 55 of the water tank 13. The water flow generated by the rotating water turbine 73 passes through the first water flow passage port 55 via the blowout port 95, and the water flow is discharged therefrom to the second water flow passage port 42 of the treatment tank 12.

An upper pressing portion 97 serving as a tab for fixing the rectifying unit 74 by being pressed against the partition wall 56 of the water tank 13 is provided above the vicinity of the tip of the air outlet 95. In addition, a hole for passing the rotating shaft 83 is formed at both ends in the axial direction of the rectifying unit 74, and a side introduction port 96 having a size for sufficiently supplying water to the rotating water turbine 73 is also provided from here. It may be provided.

Further, a lower hooking portion 98 for preventing the rectifying portion 74 from shifting in the front direction by being hooked on the lower plate 72 is provided below the side surface introduction port 96.

Furthermore, the rectifying unit 74 is provided in such a range that the intake portion, which is a hole or notch for increasing the amount of water supplied to the rotating water turbine 73 contained therein, can maintain the rectifying function of the rectifying unit 74.

The front plate 92, which is a plate on the water tank 13 side of the rectifying unit 74, has a front water intake 100 for taking water into the rotary water turbine 73 from the partition wall 56 side. The height of the front water intake 100 extends from slightly above the rotating shaft 83 of the rotating water turbine 73 to the vicinity of the lower end. The lateral width of the front intake 100 is substantially equal to the axial length of the arcuate blades 82 of the rotating water turbine 73. Thereby, water can be taken in over the whole axial direction. On the partition wall 56 side, the rotation of the rotary water turbine 73 is directed downward, and even if this side is opened, the merit of securing the supply amount is greater than the weakening of the water flow.

On the other hand, the rear plate 91 is provided with a rear water intake portion 101 for taking water from the outer wall 65 side into the rotary water turbine 73 in a form in which meat is removed from the lower side. The rear water intake unit 101 includes a central water intake unit 102 provided at an axially central portion and a lower rear water intake unit 103 provided over the entire axial direction. The central water intake portion 102 is cut from below to a height in the vicinity of the rotary shaft 83, and exhibits an effect of assisting water supply to the central portion in the axial direction where water is difficult to reach. However, if the central water intake 102 is too wide in the axial direction, it is preferable to suppress the length in the axial direction because the upward water flow easily diffuses in that portion. The lower rear intake portion 103 extends substantially in the entire axial direction, but when reaching the height of the rotary shaft 83, the upward water flow is diffused without reaching the rectifying portion 74. It is preferable to suppress the height to about −45 degrees from the rotation shaft 83.

By supplying water from the front water intake 100, the rear water intake unit 101, and the side surface introduction port 96 to the rotating water turbine 73, it is possible to secure water supply even when the water turbine is rotated at a sufficiently high speed. In particular, when the processing object 31 is heavy and requires a strong water flow, the size of these water intake portions may be increased.

With such a configuration, after use, the rectifying unit 74, the rotating water wheel 73, and the lower plate 72 can be removed in order and cleaned easily. Moreover, there is no tubular part and it is hard to block | close in the first place. Note that the fixing base 71 may be completely fixed to the bottom surface or may be removable.

On the other hand, on the outside of the side wall 61 of the outer water tank 14, a working disk 67 containing a permanent magnet attracting the passive disk 87 by a magnetic force at a position facing the passive disk 87 of the rotating water wheel 73, and a motor 66 for rotating the working disk 67. Is attached. With respect to the rotation direction of the rotary water turbine 73, the back plate 91 side is upward and the front plate 92 side is downward. Since the downward flow is stopped by the portion of the lower plate 72 that has not been thinned, the occurrence of an excessive water flow is suppressed. Then, the water supplied upward from the gap through the lower plate blanking portion 79 becomes an efficient strong water flow by the upward rotation of the rotary turbine 73, and is bent and blown by the cross-section arc-shaped portion 93 while suppressing the loss. By being sent to the outlet 95, a strong water flow is generated so as to cover the entire area near the water surface of the treatment tank 12. This water flow collides with the curved surface portion 48 provided under the chute 41 of the treatment basket 12 and flows downward, so that the treatment object 31 can be efficiently processed while rotating in the treatment basket 12.

While the rotary water turbine 73 is rotating, a pressure difference due to the generated water flow occurs, and the water level of the outer water tank 14 becomes low, while the internal water levels of the water tank 13 and the treatment tank 12 become high. In order to suppress the water level difference generated at this time, it is desirable to secure a certain volume of the outer water tank 14 with respect to the water tank 13, and this may be ensured by the volume of the side buffer 62. The water level in the treatment tank 12 rises, and the portion exceeding the front tank 45 and the side tank 46 flows down to the outer water tank 14 and circulates again as a water stream from the rotating water turbine 73.

In this circulation, it is desirable that the object to be treated 31, the waste 32 separated from the object to be treated 31, food waste, and the exclusion object 32 such as fats and oils should not be caught in the rotating water turbine 73. Therefore, the front mesh 35 for receiving the exclusion 32 included in the water falling from the front ridge 45 to the rectifying unit 74 is provided on the upper pressing portion 97 of the rectifying unit 74 and the outer peripheral wall opposite thereto. It attaches between the front hooking parts 64 which are the level | step difference made. In addition, the front edge part 53 which is an upper end part of the partition wall 56 protrudes to the outer water tank 14 side. By pushing the front mesh 35 under the projecting portion, the force that the rectifying unit 74 lifts due to the water flow can be pressed by the projecting portion of the front edge 53 via the front mesh 35. An enlarged view of this portion from the axial direction is shown in FIG.

Further, on the side surface of the treatment basket 12, as in the case of the front surface, a side wall mesh 36 for receiving the exclusion 32 contained in the water falling from the side wall 46 to the side buffer 62 is provided between the side wall 61 and the side edge 54. Is passed in between. In the case where almost no exception 32 is generated, such as a sterilization process, a heating process, a thawing process, or a cooling process, the side mesh 36 may be omitted. However, since the front mesh 35 also serves as an upper restraint of the rectifying unit 74, it is desirable to attach components having the same shape even when the exclusion 32 does not occur.

The processing object 31 that can be processed by the food processing apparatus according to the present invention is not particularly limited, marine products such as meat, fish, shellfish, crustaceans, agricultural products such as vegetables, grains, fruits, and beans, meats and agricultural products, Examples of processing objects include intermediate processed products and food processed products that have been cut and cooked for marine products.

Examples of the exclusion 32 include fats and oils, hair, lye produced by heating treatment, food waste such as a processing object smaller than the standard and fragments thereof, pebbles, paper waste, insects, straw, and the like.

The food processing apparatus 11 according to the present invention can be used for cleaning, heating, or sterilization processing by adding a processing object additive or the like during washing, heating, or sterilization. Can be done at the same time. Furthermore, the washing process, the heating process, and the sterilization process can be performed at the same time by heating or adding a bactericidal agent at the time of washing.

In addition, a cover may be attached to the upper part or the upper part of the open surface of the water tank 13 as necessary when the water temperature in the water tank is heated with water near the boiling point.

The basic procedure when using the food processing apparatus 11 according to the present invention is as follows. First, a processing object 31 to be processed such as cleaning or warming is placed in a processing tank 12 stored in the water tank 13. When the rotary turbine 73 is rotated, the water in the outer water tank 14 is sucked into the rotary turbine 73 and introduced from the outlet 95 through the first water flow passage 55 to the second water flow passage 42, and It becomes a water stream that circulates inside. The processing object 31 is subjected to processing such as washing by this water flow. When the processing object 31 has been processed for a certain period of time, when the driving device 20 is driven and the rotating arm 26 is rotated upward, the inclined portion 30 at the tip of the rotating arm 26 is initially supported by the support plate. Until the contact with 44, the treatment basket 12 does not rotate so that its open surface is inclined in one direction, and moves up and down while maintaining the balance. At this time, since water falls from the bottom net part 47 to the water tank 13, the water adhering to the processing object 31 can be dropped. Further, the water can be further shaken off by vibrating the rotating arm 26. Thereafter, the processing rod 12 having the fulcrum pin 43 rotatably connected to the rotating arm 26 is rotated, and in FIG. 1, the processing object 31 falls on the chute 41 to the left in the drawing. . When the dropping is completed, the rotating arm 26 is returned, and the treatment basket 12 is stored in the water tank 13 as it was. Thereafter, similarly, the processing object 31 can be introduced to continue the processing.

When the water becomes dirty by repeating the treatment, the treatment is performed while sequentially supplying water to the water tank 13 or the outer water tank 14. If the used water overflows from the outer water tank 14 after the processing is completed or is discharged from the drain port 52, the processing can be continued while replacing the water.

The food processing apparatus 11 according to the present invention may be used while the rotating water wheel 73 is always rotated, or is rotated when the processing basket 12 is lifted by the driving device 20 and the processing object 31 is taken out from the chute 41 after the processing. The water wheel 73 may be stopped. When the rotary turbine 73 is stopped, the water levels in the outer water tank 14 and the water tank 13 are averaged.

By adjusting the angle and the number of runners such as the arc blades 82 of the rotating water turbine 73 to be used, and the rotation speed by the motor 66, the processing object 31 is stirred by placing the processing object 31 on the generated water flow. Can be separated from the object to be processed 31. In particular, in the food processing apparatus 11 according to the present invention, since the air outlet 95 is near the water surface and the water flow is concentrated near the water surface, a high cleaning effect is exerted on a material that has a specific gravity lighter than water and easily collects near the water surface. To do.

On the other hand, when the food processing apparatus 11 according to the present invention is used mainly for sterilization or heat treatment other than cleaning, an embodiment in which the front mesh 35 and the side mesh 36 are removed may be used. In this case, the upper end of the rectifying unit 74 may be pressed directly at the front edge 53.

When hot water or steam is supplied into the water tank 13 to raise the temperature of the water in the water tank 13, it is possible to heat the object to be processed supplied to the treatment tank 12 in the water tank 13. This heating process refers to a process in which heat is applied to the object to be processed through water, for example, a process in which the object to be processed is cooked, boiled or boiled. When performing the heating process, the water in the water tank 13 can be stirred, the convection of the water can be promoted, temperature unevenness can be eliminated, and the object to be processed can be uniformly heated. In order to raise the temperature in the water tank 13, a means for supplying warm water includes a method of supplying warm water or steam directly from a water supply port (not shown) provided in the water tank 13.

In addition, by adding a disinfectant to the water tank 13 to dissolve or disperse it, the object to be treated supplied to the treatment tank 12 in the water tank 13 can be sterilized. Examples of this bactericidal agent include sodium hypochlorite, calcined shell calcium, and the like. In the case of sterilization treatment, the water in the water tank 13 can be stirred, the convection of the water can be promoted, the contact opportunity between the treatment object 31 and the sterilizing agent can be increased, and the treatment object can be made more efficient. It can be sterilized.

The food processing apparatus according to the present invention may be used alone, but a plurality of food processing apparatuses 11 may be used side by side as shown in FIGS. In this embodiment, after the processing is completed in the first food processing apparatus 11a, the tip to be dropped from the processing basket 12a through the chute 41a becomes the processing basket 12b of the next food processing apparatus 11b. Similarly, the destination of dropping from the treatment basket 12b through the chute 41b is the treatment basket 12c of the next food processing apparatus 11c. Similarly, each component of the first food processing apparatus 11a will be described with a subscript “a”, and each component of the second food processing apparatus 11b will be described with a subscript “b”.

When a plurality of

food processing apparatuses

11a, 11b, and 11c are connected and used,

water channels

200a, 200b,... That connect the respective

outer water tanks

14a, 14b, 14c,... Are provided, and

shutters

201a, 201b that can close the water channels are provided. ,... Can sequentially transfer the water to be used from the upstream side to the downstream side, and perform stepwise cleaning.

The water level and water fluctuation at that time will be described with reference to FIGS. 9A to 9D, taking as an example a form in which three

food processing apparatuses

11a, 11b, and 11c are connected. First, as a basic form, the rotary turbines 73a, 73b, 73c are rotating, and a water level difference is generated between each water tank 13 and the outer water tank 14. The water level B of the water tank 13 during rotation is higher than the standard water level A during non-rotation, and the water level C of the outer water tank 14 is lower. In addition, the processing object 31 is introduced into the treatment tank 12a of the food processing apparatus 11a at the first stage, and newly supplied water is introduced into the outer water tank 14c of the food processing apparatus 11c at the final stage (water supply port 51c). . This state is shown in FIG.

When the processing in the food processing apparatus 11a is finished and the processing object 31 is discharged, when the rotary water turbine 73c is stopped, the difference in water level between the inside and outside of the food processing apparatus 11c disappears and becomes uniform. Since additional water has already been introduced at this stage, the homogenized water level is higher than the standard water level A (water level E). The height of the bottom surface of the water channel 200b is located below the increased water level (E), and when the shutter 201b that closes the water channel 200b is opened, excess water is removed from the outer water tank 14b of the downstream food processing apparatus 11b. (FIG. 9B). At this time, the rotating water turbine 73b is rotating in the food processing apparatus 11b, and the difference between the inner and outer water levels is generated. Therefore, the water level C of the outer water tank 14b is low, and water flows unilaterally from the water channel 200b. When the water is sufficiently introduced into the food processing apparatus 11b, the shutter 201b is closed and the rotating water turbine 73c is restarted to continue the processing.

The same can be done with the food processing apparatus 11b. The internal water level rises as a whole by the amount of water newly flowing into the food processing apparatus 11b. When the rotary turbine 73b is stopped, the water level is averaged at a level higher than the standard water level B. In this state, as shown in FIG. 9C, when the shutter 200a of the water channel 200a is opened, water unilaterally flows from the outer water tank 14b of the food processing apparatus 11b to the outer water tank 14a of the food processing apparatus 11a. When the water is sufficiently introduced into the food processing apparatus 11a, the shutter 201a is closed and the rotating water turbine 73b is restarted to continue the processing. Thereby, since the water which the food processing apparatus 11a has becomes excess, it drains from the drain outlet 52a suitably (FIG.9 (d)).

By the above procedure, the food processing apparatus 11c on the upstream side can perform processing with cleaner water, and the used water can be sequentially introduced into the

food processing apparatuses

11b and 11a on the downstream side. By performing the input of the processing object 31 from the food processing apparatus 11a, processing such as stepwise cleaning becomes possible.

Furthermore, the connection by the water channel 200 is not connected between the adjacent food processing apparatuses 11, but in one or more continuous

food processing apparatuses

11a, 11b, 11c. Alternatively, the bypass water channel 202 may be connected to the food processing apparatus. FIG. 10 shows a plan view of the embodiment having such a configuration. Similarly, the bypass 203 is provided with a shutter 203. The food processing apparatus 11a and the

food processing apparatuses

11a and 11c continuously use the same water, and the food processing apparatus 11c is rinsed and the used water is fed through the bypass water channel 202. In the food processing apparatus 11b through which the processing object 31 passes during rough cleaning, sterilization with hypochlorous acid water or the like, seasoning with a seasoning aqueous solution, or boil treatment with hot water by steam supply Such a treatment with another kind of liquid can be interposed.
