[0049] In some embodiments, the ratio of seasonings to livestock and poultry meat products may be as follows: for every 500 grams of livestock and poultry meat products, add 5 grams of salt, 10 grams of sugar, 5 grams of minced ginger, 5 grams of minced garlic, 2 grams of pepper powder and 3 grams of chicken essence. The various seasonings can be mixed and then put into the seasoning inlet 200.

[0050] The outer casing 2 330 is fixed to the side wall of the outer casing 1 100 by bolts. The outer casing 2 330 is provided with a negative pressure chamber 320, and a negative pressure machine 321 is provided on the side wall of the negative pressure chamber 320.

[0051] In some embodiments, the negative pressure unit 321 uses a commercially available model and is electrically connected to a commercially available switch and an external power supply.

[0052] The bottom of the negative pressure chamber 320 is fixed to a channel 340 by bolts, and a rotating component 350 is rotatably connected inside the channel 340;

[0053] In some embodiments, a plurality of food-grade hard rubber plates are symmetrically arranged on the outer circumferential wall of the rotating member 350.

[0054] The bottom of the channel 340 is fitted with a conveyor belt 400, and the top of the conveyor belt 400 is fitted with a scraper 420 and a separator 430. The scraper 420 has two displacement shafts 421 fixed inside by bolts. The two displacement shafts 421 are arranged in parallel, and a displacement motor 422 is slidably connected to the outer circumference of the displacement shafts 421.

[0055] In some embodiments, the displacement motor 422 uses a commercially available model and is electrically connected to a commercially available controller.

By setting the timer in advance, the reciprocating motion of the displacement motor 422 can be achieved in conjunction with the forward / reverse switch.

[0056] A scraper 423 is bolted to the side wall of the displacement motor 422. The scraper 423 is made of food-grade hard silicone sheet. A flat plate 424 is provided at the bottom of the displacement motor 422. A spring is provided at the top of the flat plate 424 to buffer the displacement of the flat plate 424. A food-grade elastic rubber sheet is provided on the side wall of the flat plate 424 to block food debris. A pressure plate 432 is slidably connected inside the separator 430. A second fixing plate 433 is bolted to the bottom of the pressure plate 432. The second fixing plate 433 is long and narrow. A separator 434 is slidably fitted to the bottom of the second fixing plate 433. The separator 434 is a vertically arranged square plate.

[0057] Specifically, the outer casing 100 has a feed inlet 110 on its side wall;

[0058] In some embodiments, the top of the feed inlet 110 is slidably connected to an openable baffle. The feed inlet 110 can be opened and closed by moving the baffle to both ends by hand. The baffle can protect the feed inlet 110 and prevent external dirt from entering the interior of the housing 100 through the feed inlet 110.

[0059] The top of the meat tenderizer 240 is provided with two lifting rods 241 that penetrate the outer casing 100;

[0060] In some embodiments, the two lifting rods 241 use commercially available pneumatic lifting devices and are connected to an external air pump with a control switch via a pipe thread provided by 1.

[0061] Furthermore, the rotating plate 242 is rotatably connected to the inside of the outer shell 100, and the outer circumference of the rotating disk 211 is rotatably fitted with a rotating wheel 213 rotatably connected to the inner wall of the fixed shell 210;

[0062] In some embodiments, the power input end of the rotary wheel 213 is rotatably connected to a common slow-speed motor, which is electrically connected to a common switch and an external power supply; the outer wall of the rotary wheel 213 is provided with anti-slip texture to improve the connection stability between the rotary wheel 213 and the rotating disk 211.

[0063] Furthermore, the bottom of the stirring chamber 230 is fitted with an opening and closing plate 300;

[0064] In some embodiments, the bottom of the opening and closing plate 300 is provided with a commercially available electric telescopic rod, which is electrically connected to a commercially available switch and an external power source.

[0065] The bottom of the hinge plate 300 is fitted with a collection cavity 310;

[0066] In some embodiments, the collecting cavity 310 is generally shaped like a bucket with a larger top and a smaller bottom, which makes it easier for the pre-cooked meat products to fall into the bottom of the collecting cavity 310 after the opening and closing plate 300 is opened, thereby enabling better transfer of the pre-cooked meat products through the transfer pipe 311.

[0067] It is worth noting that the output end of the transfer pipe 311 is fixed to the negative pressure chamber 320 by bolts. The negative pressure chamber 320 is cylindrical in shape. A metal ring for supporting the structure of the negative pressure chamber 320 is fixed to the outer wall of the cylinder. A gate valve 341 is provided on the side wall of the channel 340.

[0068] In some embodiments, the gate valve 341 uses a commercially available electric type, which is electrically connected to a commercially available forward / reverse switch and power supply.

[0069] It is worth noting that the bottom of the channel 340 is bolted to an inclined plate 360 ​​that fits the top of the conveyor belt 400. The channel 340 is square in shape and is made of food-grade rigid plastic sheet with a relatively thick thickness to withstand a certain amount of pressure. Opposite to the top of the conveyor belt 400 are side plates 401 fixed to the inner wall of the outer shell 330. The inclined side plates 401 can prevent the pre-cooked meat products from slipping off the top of the conveyor belt 400 when passing the bottom of the separator 430 and the scraper 420.

[0070] In addition, the power input end of the conveyor belt 400 is rotatably connected to a shaft 410;

[0071] In some embodiments, the power input end of the rotating shaft 410 is rotatably connected to a commercially available motor, and the motor is electrically connected to a commercially available switch and power supply; the outer wall of the conveyor belt 400 is embedded with a waterproof plastic film, which can prevent the moisture of the pre-cooked meat products from penetrating the conveyor belt 400 and affecting the electrical equipment inside the conveyor belt 400.

[0072] A piston rod 431 is fixedly connected to the top of the pressure plate 432;

[0073] In some embodiments, the power input end of the piston rod 431 is provided with a commonly available hydraulic cylinder. The hydraulic cylinder is connected to a commonly available hydraulic pump with a control switch via a provided pipe thread. The control switch is provided with a commonly available timer, which can control the time for the separator 434 to separate and block the pre-cooked meat products by setting the time. The side wall of the piston rod 431 is provided with a commonly available air cup to improve the tightness of the connection between the piston rod 431 and the hydraulic cylinder when the piston rod 431 is displaced.

[0074] It is worth noting that the fixed shell 210 is fitted to the top of the stirring chamber 230, and the bottom of the collecting chamber 310 is provided with a transfer pipe 311;

[0075] In some embodiments, the transfer pipe 311 is made of food-grade rigid plastic, and a metal strip runs through its interior so that the transfer pipe 311 can withstand the influence of negative pressure without deformation; a fixing ring is fixed to the outer circumference of the transfer pipe 311, and a vertical support column fixed to the inside of the outer shell 100 is provided below the fixing ring to support the transfer pipe 311 and prevent it from tilting when transferring pre-cooked meat products, so as to avoid structural damage.

[0076] In addition, the separator 430 and the scraper 420 are fixed to the inside of the outer casing 330 by bolts. The bottom of the rotating plate 242 is provided with a buffer 244, which is composed of elastic springs in a cross combination. This buffer can cushion the top of the rotating plate 242 when the meat tenderizer 240 descends, so as to avoid the large impact force of the meat tenderizer 240 from affecting the internal device.

[0077] Working Principle: When processing pre-made meat products, the meat products are first placed into the outer shell 100 through the feed inlet 110. The meat products slide onto the top of the rotating plate 242. Then, the lifting rod 241 drives the meat tenderizer 240 to descend, causing the meat tenderizer 240 to strike and tenderize the meat products, which can cause cracks to appear in the meat products. After the striking is completed, the telescopic column 243 extends, causing the left end of the rotating plate 242 to move upward, and the meat products slide into the mixing chamber 230. Then, the seasoning is poured into the seasoning outlet 200. The partition 201 and the fixed plate 202 of the seasoning outlet 200 use the gap between them to disperse the seasoning. The seasoning falls into the interior of the rotating disk 211. When the rotating wheel 213 drives the rotating disk 211 to rotate, the rotating disk 211 cooperates with the fixed plate 202 to rotate. The brush bristles on one side of the bottom of plate 202 brush the rotating disk 211, brushing the edible seasoning into the holes of the rotating disk 211. At the same time, when the holes of the fixed disk 212 at the bottom of the rotating disk 211 coincide with the holes of the rotating disk 211 containing the edible seasoning, the edible seasoning falls into the meat products inside the mixing chamber 230 after passing through the holes of the fixed disk 212 and the metal mesh at the bottom of the fixed shell 210. This achieves the dispersion and pouring of edible seasoning in the pre-cooked meat dishes. When the edible seasoning is poured, the rotating column 221 below the fixed column 220 rotates, causing the mixing column 222 to be thrown out from the outer wall of the rotating column 221, stirring the meat products. This makes the seasoning more uniform during the marinating of the pre-cooked meat dishes, avoiding uneven taste and facilitating the processing of pre-cooked meat dishes.After the pre-cooked meat and poultry dishes are marinated, the opening and closing plate 300 opens, and the pre-cooked meat and poultry dishes fall into the collection chamber 310. At the same time, the negative pressure machine 321 extracts the gas from the negative pressure chamber 320, creating a negative pressure inside. This pressure forces the pre-cooked meat and poultry dishes into the negative pressure chamber 320 through the transfer pipe 311. After the transfer is complete, the gate valve 341 opens, and the pre-cooked meat and poultry dishes fall into the channel 340. As the pre-cooked meat and poultry dishes fall into the channel 340, the rotating component 350 rotates, and the rubber plate fixed to its outer wall separates some of the pre-cooked meat and poultry dishes, causing them to fall onto the top of the conveyor belt 400, achieving simple dispersion of the pre-cooked meat and poultry dishes. The conveyor belt 400 then moves the pre-cooked meat and poultry dishes to the bottom of the scraper 420. At the same time, the reciprocating displacement motor 422 drives the scraper 423 and the flat plate 424 to reciprocate, which can spread the pre-cooked meat and poultry vegetables flat. Then, when the pre-cooked meat and poultry vegetables reach the bottom of the separator 430, the piston device is controlled by the timer switch, which causes the piston rod 431 to drive the pressure plate 432 to fall. The pressure plate 432 drives the separator 434 to contact the top of the conveyor belt 400 to block the pre-cooked meat and poultry vegetables. After a certain time, the piston rod 431 drives the pressure plate 432 to drive the separator 434 to retract. The pre-cooked meat and poultry vegetables are divided into small piles by timed blocking, so that the pre-cooked meat and poultry vegetables are discharged in piles, which facilitates the later packaging and transfer of the pre-cooked meat and poultry vegetables and improves the processing efficiency of the pre-cooked meat and poultry vegetables.
