[0048] In the working process, a plurality of white chickens are placed on one shelf 5, and the chickens have holes left by slaughtering at the buttocks and necks; the support frame 13 is a conical structure, so that the support frame 13 can be inserted from the chicken buttocks and passed out of the hole on the neck; compared with the traditional hanging basket form, the advantages are that the hot water in the cooking pot 21 penetrates the inside of the chicken during the rolling process from bottom to top, so that the chicken is uniformly heated inside and outside; when the shelf 5 is hung up, the water and fat will quickly drain from the inside and outside of the chicken; the mechanical arm load is reduced;

[0049] The whole processing process is: the feeding unit 1→the cooking unit 2→the water cooling unit 3→the air cooling unit 4;

[0050] The gripper 67 of the first transfer unit 6 hooks two cross bars 14, rises, and then the rail car 62 moves along the rail 61 to above the cooking pot 21, and then the motor 65 drives the lead screw 64, the lead screw 64 drives the lifting mechanism 66, and the lifting mechanism 66 immerses the shelf 5 fixed by the gripper 67 into the cooking pot 21; the cooking pot 21 is arranged side by side, and each shelf 5 is immersed into each cooking pot 21 in turn according to the principle of first-in first-out; after the shelf 5 is completely immersed into the cooking pot 21, the power output end of the pneumatic cylinder 68 is elongated, the gripper 67 is released, and then another shelf 5 is moved. Recycle, realize that the shelf 5 is immersed into each cooking pot 21 in turn; and then enter the water cooling unit 3;

[0051] Preferably, the cooking unit 2 and the water cooling unit 3 are provided with a transfer area 7; the upper part of the water cooling pool 31 is provided with a second transfer unit, and the second transfer unit and the first transfer unit 6 have the same structure.

[0052] The first transfer unit 6 is used for transferring the shelf 5 from the feeding unit 1 to the boiling unit 2 and the transfer area 7;

[0053] The second transfer unit is used for transferring the shelf 5 from the transfer area 7 to the water cooling pool 31;

[0054] The function of the transfer area 7 is to transfer the shelf 5 and drain the water and oil on the chicken, so as to avoid bringing into the pool;

[0055] The transfer area 7 comprises a base 71 arranged on the ground, four right-angle triangular prisms 72 for supporting four corners of the shelf 5 arranged on the base 71; the upper surface of the base 71 is a concave surface which is concave to the center; a discharge port 73 is arranged in the center of the concave surface; a gas pipe 74 and four nozzles 75 connected to the gas pipe 74 are arranged in the middle of the base 71, and the nozzles 75 are directed to the supporting surface of the right-angle triangular prism 72; the gas pipe 74 and the nozzles 75 are lower than the supporting surface;

[0056] Since the accumulation of oil is easy to breed bacteria, several nozzles 75 are arranged to continuously or intermittently blow air to the supporting surface, so as to keep the supporting surface clean; the generated water and oil are discharged through the discharge port;

[0057] The second transfer unit moves the shelf 5 in the transfer area 7 into the water cooling pool, and the water cooling pool also adopts the principle of first-in first-out, and the shelf 5 which enters last is arranged on the side closest to the boiling unit 2;

[0058] As a preferred embodiment of the present application, the water cooling pool 31 is divided into a material area 34 and a refrigeration area 35 by a partition plate 33; a water inlet pipe 36 and a drain pipe 37 are further arranged; the water inlet pipe 36 is arranged at one end of the refrigeration area 35 away from the boiling unit 2; the drain pipe 37 is arranged at one end of the material area 34 away from the boiling unit 2, and the drain pipe 37 is arranged on the side plate of the material area 34 away from the refrigeration area 35; the partition plate 33 is provided with intervals for communication between the material area 34 and the refrigeration area 35 at both ends; the refrigeration pipe 32 is arranged at the bottom of the refrigeration area 35; the water inlet pipe 36 is connected to the lower part of the side wall of the refrigeration area 35; and the drain pipe 37 is connected to the upper part of the side wall of the material area 34.

[0059] Reference is made to the accompanying drawings Figure 6 It can be seen that the cold water circulation of the present application is from A→B→C→D and E→A in the drawings; it can be seen that in the material area 34, the water temperature is lower closer to the boiling unit 2, so as to achieve the purpose of rapid cooling, so as to keep the characteristics of fresh and tender chicken;

[0060] One optimization of the present application is that the upper and lower arranged drain pipe 37 and circulation pipe 38 are designed, specifically, the circulation pipe 38 is connected to the water inlet pipe 36, and the circulation pump is connected to the circulation pipe 38; the circulation pipe 38 is located below the drain pipe 37 and close to the bottom of the side wall of the material area 34; the drain pipe 37 actually drains water through the effect of overflow, mainly used for discharging the surface oil-containing water, keeping the water body in the pool clean; at the end of production, the water in the pool can be drained through the circulation pipe 38 or the water inlet pipe 36 or an additional emptying pipe is arranged at the bottom of the pool.

[0061] Compared with the pool without partition, the partitioned pool has better refrigeration effect, because it keeps the rapid water flow in contact with the refrigeration pipe 32 to achieve rapid cooling, and at the same time, the lowest water temperature first cools the high-temperature chicken to achieve good meat quality control; by constructing the inner circulation (the interval formed by the partition plate 33 and the pool) and the outer circulation (the circulation pipe 38), compared with the single outer circulation, the circulation flow is improved, the heat exchange speed is improved, and the rapid cooling is maintained. At the same time, it also avoids damaging the refrigeration pipe 32 of the shelf 5.

[0062] During the experiment, it is found that due to the effect of the partition plate, when the water inlet pipe 36 is arranged at the position of the gap of the partition plate, the outer circulation forces water to enter, which can cause a low pressure area at this position, and a large amount of water in the material area will flow into the refrigeration area, which can improve the water flow in the refrigeration area, improve the refrigeration heat exchange speed, and at the same time, reduce the problem of slow water flow speed and poor cooling effect caused by filling the material shelf in the material area.

[0063] Through the design, the taste of chicken can be obviously improved, compared with the traditional cold water pool, the temperature control is accurate, energy-saving, and the chicken quality control becomes easier.

[0064] Preferably, the lifting mechanism 66 is hinged with the air cylinder 68; the power output end of the air cylinder 68 is hinged with the claw 67; the claw 67 is L-shaped; the claw 67 is bent from between the two horizontal rods 14 to the direction close to the horizontal rod 14 to hook the horizontal rod 14; the support frame 13 on the frame 12 is divided into multiple rows, and the support frames 13 of adjacent rows are staggered; the air cooling unit 4 comprises an air cooling tunnel 41 and a chain track 42 located in the tunnel; the second transfer unit is used for transferring the shelf 5 from the transfer area 7 to the water cooling pool 31 and the input end of the chain track 42.

[0065] In the present application, the side of the gripper 67 contacting the shelf 5 is fixed with polytetrafluoroethylene to keep clean and buffer collision; the gripper 67 is composed of two side plates and a connecting rod connecting the two side plates, the power output end of the air cylinder 68 is hinged on the connecting rod; the side plate is generally L-shaped, but preferably, the end connected with the lifting mechanism 66 is a gradually widened plate body 69, which gradually increases in width from the lifting mechanism 66 to the end of the gripper 67, and we found in repeated verification that the plate body of this structure has greater bearing capacity.

[0066] As a preferred embodiment of the present application, the lifting mechanism 66 is actually a threaded sleeve 64, and the outer part of the threaded sleeve 64 is further fixed with an auxiliary plate, the auxiliary plate is hinged with a section of the gripper 67; sliding rails are further arranged on the left and right sides of the support 63, and sliding blocks are connected on the two sides of the lifting mechanism 66, which are in sliding fit with the sliding rails to improve the lifting stability of the lifting mechanism 66.
