Description

The present invention relates to a method and apparatus for the pre-cooling of slaughtered, eviscerated and cleaned animals, in particular poultry, rabbits, small game and the like.

During the large-scale poultry processing process, live poultry delivered to the processing plant must be chilled to -F4 ° C (so-called core temperature) as soon as possible after being slaughtered, gutted and eviscerated, and pre-cooled before further operations such as cutting. The type, duration and hygiene characteristics of the pre-chillings have a decisive influence on the quality of commercial poultry in general, including its aesthetic appearance and bacteriological characteristics. It is important that the product is not adversely affected in color or taste during pre-cooling.

Pre-cooling solutions are known in which baronafics immerse themselves in a common water bath used as a heat exchanger. In the common water bath, for example, a snake in a spiral line is used, and cooling systems with screw or agitator are used.

These solutions have the following serious drawbacks:

- since the bodies are immersed in a common water bath, there is a clear risk of cross-contamination (salmonella, coli bacteria, etc.):

- one pass through the water bath (ηθη);

- as a result of diving in a common water bath, even with intensive water bath refreshment, the product suffers from an unfavorable change in odor or taste;

- in the case of prolonged submersion, it is inevitable that the water content of the product will be between 6% and 8% of the body weight, but this may be up to 10-18% when increasing the water bath flow rate and / or cooling time can also increase. The high water content of the product not only creates unfavorable conditions from the hygiene point of view, it also impairs the storage and preservation of the product after freezing and, in the end, the so-called post-freezing conditions. Water that is released when it is "thawed" makes the consumer feel discouraged. Conversely, if this "foreign" water content is to be removed from the poultry, at least in part, this can only be achieved by the introduction of a costly drip stage or equipment facilitating the same time as the pre-cooling period;

- the specific energy use of immersion bath solutions is relatively high due to the unfavorable heat transfer conditions;

- the simultaneous pre-cooling of each poultry carcass, so that the same core temperature of the poultry leaving the pre-chilling system is not, or is difficult to achieve.

In order to overcome the above disadvantages, spray water cooling systems have also been developed. They move wire mesh baskets on a vertical path, using the patron-noser principle, simply by spraying the product inside. Baskets run several laps until the products reach the right temperature. The disadvantage of these solutions is the branch2

2.5 operation, low power and high water and energy consumption.

It is an object of the present invention to provide a method and apparatus for pre-cooling poultry carcasses and the like, whereby the desired body temperature of + 4 ° C can be obtained for each product; body water uptake is below 5.5%; the specific water consumption is lower than before; the product also meets the highest hygiene standards and requirements; and which technology is hygienic, infection free.

The invention is based on the discovery that if water sprayed. washing, .and. .cooling is combined with air circulation surface cooling and drying, while meeting hygiene, quality and economy requirements. ·,

Based on this discovery, the object of the present invention has been solved by a method of spraying animal carcasses with water, characterized in that the precooling is carried out in three stages such that the bodies in the first stage are washed and cooled by spraying with water at a temperature lower than its temperature; in the second stage, the bodies are sprayed with water and blown to the wet bodies by evaporative cooling; in the third stage, the surface of the bodies is further cooled and dried by a hot air circulation method. It is expedient that in the first stage the bodies, which are kept in motion at a temperature of generally about 30-32 ° C, are sprayed with fresh water at a temperature of 8-18 ° C (drinking water temperature), preferably intermittently, and and using at least 1.5 liters / kg of water, based on the weight of the bodies to be cooled, and keeping the bodies moving for about 3-5 minutes.

In a further preferred embodiment of the process, in the second stage, evaporative cooling is applied to the bodies at a temperature of 8-18 ° C (drinking water temperature), preferably periodically, preferably in several places, with freshly taped water, and Blowing air at -5 ° C; and in the third stage, air is blown onto the bodies at a temperature of about 0 ° C to about 5 ° C. In the three phases, the carcasses are guided through a constant, steady-speed moving movement, preferably in the upper course, and in the second phase, the carcasses are kept in motion for a period of about 15 to 20 minutes. The bodies may remain in the third stage for the same period of time.

The apparatus for carrying out the process has cooling chambers and a conveyor path through the chilled chambers, and is characterized by a compartment containing a washer-cooling section; a compartment comprising a wet-cooling section and a compartment containing a cooling-drying section, said spaces being guided by a top conveyor; one or more separate wetting units in the wash-cooling section, one or more wetting units in the wet-cooling section, and both in the wet-cooling section and

184,465 air-cooled air coolers in and out of the freeze-drying section; and that the apparatus has a conveyor-mounted hanging device capable of holding the bodies. Preferably, the wetting units are movable in the longitudinal direction of the conveyor, and the spaces are separated by insulated partitions. According to a further feature of the invention, there is a loading area outside the building boundary, outside the building enclosure, before entering the washer-cooling section, after removing the refrigerator-drying section, and after the unloading area, a washer-disinfectant. An embodiment of the apparatus having a heat recovery heat exchanger for cooling the water to be supplied to the washer-cooling section, having on the one hand waste water leaving the wet-cooling section and / or the cooling-drying section on the other hand, and fresh water is passed through. In this case, it is expedient to have a pool (reservoir) for receiving water exiting the wet-cooling section and / or the cooling-drying section, which is connected by a line containing a filter and a pump to the heat recovery heat exchanger.

According to another feature of the invention, the pick-up area is provided with curved push rods cooperating with the body support hanger.

For hygienic reasons, the wetting units include spray heads directed to the bodies, preferably in adjustable position, and overlapping, labyrinth-like, slanted overlapping discs, which overlap each other from top to bottom, The suspension rods of the suspension structures have curved rod portions allowing such a maze-like arrangement of these plates.

The invention will now be described in more detail with reference to the accompanying drawings, which show a preferred embodiment of the apparatus and some structural details.

As shown in Figures 1 and 2, the apparatus has a wash-and-cool section A, a wet-cool section B, and a cool-dryer section C. These sections are located in the spaces 1, 2 and 3 separated by partitions 7 and 11 of the building, all of which are designated by reference numeral 5, in which the conveyor 4 is guided, some parts of which extend outside the building 5. In Figure 1, the conveyor is indicated by a dotted line. 6 loading points are provided for the introduction of slaughtered, eviscerated and feathered poultry into the pre-cooling system; this is where the bodies are hung on the hooks (to be described in more detail later). In this wall 18, a cavity 6a is formed, through which the conveyor is introduced into the space 1.

In space 1, a humidifier unit 26, as shown in Figures 2 and 3, is provided which is rollable and is supplied with water fed through a water inlet pipe 21, a heat recovery heat exchanger 22 and a spray water inlet pipe 24. 2 and

Figure 3 shows the wires).

In the partition 7, in the region of the end of the space 1 opposite the opening 6a, an opening 8 is formed in the partition 7, through which the conveyor 4 is led into the space 2.

The width of the space 2 is several times the width of the space 1; whereas in compartment 1, i.e. in the washer-cooling section A, there is only one conveyor path, in compartment 2 there are 6 conveyor paths running parallel to each other (otherwise the lengths of spaces 1, 2 and 3). In space 2, below the conveyor, there are two wetting units 9 (for the sake of clarity only one is shown in Figure 2) in which water conveyed by the conveyor 4 can be sprayed on the bodies. The humidifier unit 9 is supplied with water from a conduit 35 which is directly connected to the mains water conduit (Figures 2 and 3). The wetting units 9 in the space 2 may be unrollably disengaged in the line of the conveyor 4.

In the space 2, i.e. in the wet-cooling section B, there are cooling units 10a, preferably formed by non-cooling air coolers. Each cooling unit 10a has two fans 10 (1 and 2 and 3, respectively). From the cooling units 10a, the entire space 2 can be filled with cold air.

The water sprayed from the space 2 and the outlet of the cooling unit is fed via the conduits 36, 37 to the control tank 28 (Figures 2 and 3), which is connected via the conduit 29 to the aforementioned heat exchanger 22. A pump 30 and a filter unit 31 are provided in line 29. A conduit 27 connected to the overflow from the tank 28 is introduced into the public sewer.

Returning to Fig. 1, the cooled product in section B is conveyed through the opening 14 of the partition wall 11 to the conveyor 4 into the space 3, i.e. the refrigerator-drying section C. In this embodiment, the conveyor has eight parallel orbits in space 3. Also in space 3 there are four cooling units 10b formed by cyclically operating cooling air coolers, but

Other types of refrigeration units operating at temperatures of about 0 ° C may be used as refrigeration units. It should be noted that there is also a space 33 separated by a partition 32 between spaces 2 and 3, in which on the one hand the empty branch of the conveyor is led back (1 later) and on the other hand the cooling units 10a There is also a space 34 between the wall 11 and the wall 45, from where the cooling units 10b flow into the space 3. In the walls 32 and 45, openings 32a and 45a are provided for passing the conveyor 4. The side walls of the building and the partitions 7, 11 are thermally insulated because they confine spaces of different temperatures, while the walls 32 and 45 have only a space-limiting role and can be made of simple metal sheet. The fans of the cooling units 10b are also designated 10 '(Figures 2 and 3). The conveyor 4 exits through the opening 15 of the wall 13 (1. upper left in FIG. 1) and is provided with a stripper 16 and a washer-disinfector hood 17 for its outwardly directed section, and the conveyor 4 is leading to the building 5, it extends along its length behind the cooling units 10a and exits again through the opening 19 of the opposite wall 18 to the loading bay 6 and back to begin the description of the apparatus.

In Fig. 4, the suspension 38, shown in full scale with reference numeral 38, is connected to the conveyor 4. By means of conveyor 4, here rollers 46 are moved by means of rollers 46, which are turned downwards on steel T-shaped beam 4a. The chain used as a means of moving is not shown in Figure 4, which will be described later

9. The axis of rotation of the rollers is indicated by a dotted line and reference numeral 47. A profile 48 is mounted to the shaft 47 in a pivotable manner. The suspension means 38 has a rigid rod 39 for which you have two. At the level, the orifice clamps 40 extending outwardly on one another are fixed: these will be described in more detail below.

Marta is also connected to the above-mentioned suspension body 48 by means of articulated movement of the rod 39. The means for forming the wrist are the dashed axes 49 and 51 (stanchions and the member 50).

The two of you, ί; Inclined between levels - the baffle plates 41 extending outwardly and downwardly from the rod are fixed in the wetting units 9 shown in FIG. which ensure the drainage of water flowing from your poultry bodies 42, vagvis are prevented from passing from the upper level bodies to the lower level bodies. This is how we meet our very important hygiene ambassadors. The plates 41 overlap each other v due to the section 39a of the rod 39 being deflected from the geometrical axis of the rod above the lower clamping members 40. The plates 41 also provide for the deflection and guiding of the rods 39 as exotic.

Because the 39 bars are a single nonton. by means of a shaft 49 passing through a fork 56 at the upper end of the rod, it is pivotally connected to the suspension body 48 moved by the conveyor 4, the suspension 38 always being in equilibrium position, for example in the ascending or descending conveyor track; .

It is noted that the structural members of the suspension members are corrosion-resistant, for example stainless steel or plastic suitable for food purposes.

The above-mentioned items 1-3. 4a and 4b are shown in Fig. 4. It can be clearly seen that water from the spray heads reaches the poultry bodies from all directions, so that they are perfectly wetted. Similarly, the spray heads are arranged in the humidifier unit 26 in space 1. The sprinkler heads 43 are supplied with water from line 35 (also Figures 1 and 2), in which a valve 35a is incorporated. This ensures that the nozzles can be operated intermittently, thus minimizing water consumption. The special nozzles give the "full pyramid" or "full cone" spray pattern shown. The position of the spray heads 43 is adjustable to provide optimal wetting of poultry bodies at all times.

The curved push rods 44 in Fig. 4 (also the larger scale in Fig. 6) are fixed only in the unloading position 16 shown in Fig. 1. Thus, as shown above, of the structural members shown in Figure 4, the members 4, 41, 43 and 44 are stationary and do not form part of the actual suspension structure 38, but work together with them, so that their representation is well-understood.

4 and 5, it is clear that the clamping members 40 are made of sheet metal, e.g. made of stainless steel sheet; viewed from above, they are rectangular, fixed to the rod 39 by means of holding plates 52, and in the direction ff of the suspension means 38 have angular apertures 53 extending to the edge of the element 40 and tapering from the outside to the inside. In the present embodiment, there are six or six openings 53 on each side, each leg of each chicken being tucked into an opening 53, so that a suspension device of Figures 4 and 5 can hold six chickens at a time.

Figure 6 shows a larger scale design of an opening 53 in accordance with the present invention, and also illustrates a push rod 44 in its position relative to the opening at the pick-up location 16 shown in Figure 1. The openings 53 are tapered from the outside to the inside, ie? and their longitudinal axis Zi is at an angle to the axis Zi perpendicular to the direction of travel indicated by the arrow H. The inner end of the apertures 53 and the flanges are rounded at the protrusion. Note that the other two openings in Fig. 6 are only indicated by their Z axis. Preferably, the value of a is about 45 °, and the geometric axes Zi enclose an obtuse angle β with the direction H, i.e., the dotted line. As shown in Figure 4, the push rods 44 are located just below the clamping members 40 so that they fall under the openings 53 and are convex when viewed from the projection 53a of the openings. Under these geometrical conditions, the clamping member 40, along with the entire hanger 38 (Fig. 1), moves in the direction of arrow H, and chickens enter the slots 53.

184,465 are padded by their leg umbrellas, and due to their curvature, the push rods 44 push the chickens out of the gripping members 40, i.e., the picking is carried out automatically at the picking point 17 (Fig. 1).

The clamping member 40 of Fig. 7 differs from that of Fig. 6 in that the opening 53 is formed by a suitably curved rod 54 having a circumference between the opening 53 '. The longitudinal axis Zi of this also has an obtuse angle β with the direction H, is 45 °, and the opening narrows inwardly from the abutment 53a, but is expanded by breaking the rods 54 in its abutment region. The bars 54 may be secured to the plate 40 of the clamping member 40 by welding.

8 and 9, the spray heads and push rods are no longer marked. Here, the conveyor 4 has a beam Ib made of steel I-profile, on which rollers 46 are moved, and the whole of the suspension mechanisms designated by reference numeral 38 is provided by the chain 55 shown in FIG. The rollers 46 are connected to these suspension bodies 48 by the shafts 47 (1 also in Figure 4). In the exemplary embodiment of Figures 8 and 9, the clamping members 40 are also located at two levels as in the embodiment of Figure 4, but the rods 39 have a support bar 58 perpendicular thereto. secured by welding, to which two suspension rods 57 are connected, and to these are clamped members 40, which, e.g. 5-7. or 10. The openings 53 are indicated by dashed lines in Figure 9. As shown in Figure 9, the coupling members 50 here are elongated strap-like members, and each pair of coupling members 50 is joined by two pairs of rollers 46. It is also shown in Fig. 9 that the adjacent suspension means, designated by reference numeral 38, are connected to each other by the articulated linkage 59. The pivot link 59 is formed by an inwardly extending rod 53 hingedly connected to a pair of rollers 46 and a rod 51, 52 hinged to the pivot 53 and pivotally connected to the pivot 53 and 52. The holes 54 allow the n spacing to be varied according to various conveyor path conditions. The articulation arm 50 prevents adjacent suspension members from slipping into one another and colliding, since it restricts their freedom of movement and allows adjacent suspension devices to travel vertically and at an appropriate distance on inclined conveyor sections.

The section 57a of the suspension rods 57 of the structure of Fig. 8 is also bent in an S-shape, resulting in the aforementioned H spacing in relation to Fig. 4; Thus, no water can pass from the upper level poultry to the lower level (also Figures 1 to 4).

Figures 10 and 11 show a further preferred embodiment of the clamping device with reference numerals already used in Figures 6 and 7. Here, the value of α is 30 ° and the angle γ (Fig. 11) by which part of the plate 40a is bent is approximately 30 °. The apertures 53 'are tapered from the outside to the inside and are thus substantially the same shape as the apertures 53, 53' shown in Figures 6 and 7.

The apparatus according to the invention is operated as follows:

1, the poultry bodies 42 are tensioned by their thighs into the openings 53 (Fig. 1, Fig. 5) of the catch members 40 of the conveyor 38 moved by the conveyor 4 (Fig. 4). If the tray-like clamping member 40 has six or six openings 53 on each side, twelve carcasses may be disposed on a hanger 38, since there are two clamping members 40 on two levels. The carcases are eviscerated and cleaned of feathers.

The direction H of the conveyor 4 is shown in FIG. 1 with arrows drawn on the dotted conveyor path.

The loaded hanger 38 enters through the opening 6a into space 1, i.e. the wash-cooling section A, and therein enters the humidifier 26, which has the spray heads shown in Figures 2 and 3. The humidification unit 26 is sprayed with cold fresh water to poultry bodies at temperatures of about 30-32 ° C. The water may be fresh mains water, but the heat utilization heat exchanger 22 (Figures 2 and 3) may reduce its temperature. At least 1.5 l / kg of water are used for poultry carcasses. By spraying, the poultry bodies are washed and cooled.

When spraying with water at + 10 °, the "crust" temperature of poultry bodies kept in motion during the wash-cooling period A for 2-3 minutes is approx. Decreases below +20 ° C. Cooling may be enhanced by inserting one or more additional humidifying units 26 into the section A and / or by pre-rolling the unit 26 and applying another spraying operation.

From the space 1 through the opening 8 into the space 2, i.e. the humidifier-cooling section B, a carcass-containing suspension device is provided, which comprises several humidification units 9. These are clearly seen in Figures 2 and 3, and Figure 4 illustrates how the spray heads 43 of the wetting unit 9 are arranged relative to the hanger 38 and the plates 4i eliminate the water dripping from above at the lower level. drip on existing poultry bodies.

In the wet-cooling section B, the poultry bodies are also sprayed with water at a temperature of 8-18 ° C, i.e. fresh tap water at a drinking water temperature. In section B, the suspension carcass 38 containing the carcass passes for 15 to 20 minutes, during which the carcasses are sprayed repeatedly, i.e. intermittently, with the cooling units 10a spraying cold air at a temperature of 0-5 ° C throughout the space with the aid of fans 10 '. . The air circulation in space 2 is detected by the arrows a and b in Figures 2 and 3.

In the wet-cooling section B, non-settling air coolers are used to cool the poultry carcasses evoporatively. To this end

184,465 of the 9 wetting units are used, and they are moved so that there is a constantly evaporating water film on the bodies. This maintains the evaporative cooling effect continuously. When the carcasses leave section B through the opening 12 and enter the refrigerator-drying section C, the surface layer, i.e. the "bark" area, has cooled down to about + 5 ° C and naturally the inner part, i.e. the "core" ”Temperature.

In the refrigerator-drying section C, the air coolers 10b (cyclically operating, cool air coolers, or refrigerators operating at about 0 ° C) produce the air circulation shown by arrows c and d in FIG. The supply air temperature can be 0-5 ° C. In section C, there is no spraying anymore, only air circulation drying and simultaneous further cooling are carried out for a period of 15 to 20 minutes while the suspension means 38 passes through space 3. When the poultry carcases in the aperture 15 (Fig. 1) leave the refrigerator-drying section C, their crust temperature is below + 4 ° C, i.e. the amount of cold introduced into the crust is also sufficient to remove heat from the core. The poultry from Stage C is placed in a treatment room at a temperature of about + 10 ° C, where the temperature of the kernel and crust is balanced. From the clamping members 40 (Figs. 1 and 4) of the hanger 38, the arcuate push rods (Fig. 6) fixed at the removal point 16 are automatically removed and transported for further treatment.

The hanger 38 is washed and disinfected along the section of the conveyor 4 outside the building 5 (of course, in another enclosed room), after the removal 16, at the washing and disinfection site 17 and returned through the opening 14 to the space 33 containing the cooling units 10a. conveyor to the 6 loading bays and the operations described above will start again.

Advantageous effects of the invention include:

each animal body is always in contact with fresh water, so hygienic conditions are improved and the risk of cross-contamination is excluded. The optimum product quality is always ensured by the expected technological parameters. The variable conveyor conveyor provides step-by-step product cooler treatment. Continuous unit costs per unit of product are reduced, water and cooling energy utilization is more favorable, and the equipment can be operated more economically than currently known systems. The water uptake of poultry carcases during pre-chilling may be reduced to 2 to 3% instead of the current 8 to 12% by weight. The structural system and service are simple, the operation is automatic.

The invention is, of course, not limited to the described embodiment of the method and to the illustrated embodiment of the device or suspension as described, but can be practiced in many ways within the scope defined by the claims.
