Description

Technical Field

[0001] This utility model relates to the field of quick-freezing equipment technology, specifically a rapid freezing device for the hindquarters of cattle. Background Technology

[0002] Rapid freezing (below -18°C) causes the internal moisture of meat to solidify quickly, forming numerous small ice crystals. Compared to the large ice crystals produced by slow freezing, the small ice crystals can be evenly distributed between muscle fibers, avoiding puncturing cell membranes and reducing juice loss during thawing. Therefore, rapid freezing equipment is often used in meat production to freeze and preserve meat products, thereby ensuring the quality of meat products after thawing.

[0003] In the prior art, patent publication number CN218065471 U discloses a quick-freezing device for freeze-dried beef production, including an equipment box and a quick-freezing box. The equipment box is installed in the middle of the top of the quick-freezing box, and a quick-freezing chamber is provided in the middle of the interior of the quick-freezing box. Storage boxes are sleeved on both sides of the quick-freezing box near the rear surface. A bottom plate is installed on both sides of the quick-freezing box near the rear surface. An electric telescopic device is installed in the middle of the front surface of the bottom plate. The output shaft of the electric telescopic device is connected to the storage box through a side plate. A refrigeration unit is installed on one side of the bottom of the equipment box. An atomizing box is installed on the bottom of the equipment box next to the refrigeration unit. A blower is installed in the middle of the top of the equipment box. The input end of the blower is connected to the refrigeration unit through an air inlet pipe. The output end of the blower is connected to an ejector through a blower pipe. A conveying pipe is installed at the end of the ejector.

[0004] The quick-freezing equipment used for freeze-dried beef production has the following disadvantages: it uses liquid nitrogen to quickly freeze meat products placed inside the storage box. Since the beef products are placed inside the storage box, the side of the beef products in contact with the lower surface of the storage box often freezes more slowly than the side that is not in contact with the lower surface of the storage box. This requires operators to turn the beef products over or extend the quick-freezing time in order to freeze the beef products quickly and completely. To address this, we propose a quick-freezing device for the hindquarters of cattle. Utility Model Content

A protective door 15 is hinged to the left surface of the quick-freezing box 1, and a transparent observation window is fixedly connected inside the protective door 15. A polyurethane insulation layer is provided on the inner surface of the quick-freezing box 1. A control switch group 2 is fixedly connected to the front surface of the quick-freezing box 1, and the input terminal of the control switch group 2 is electrically connected to an external power source. The quick-freezing box 1 has an internal rear surface with a mounting groove. An electric push rod 8 is fixedly connected in the mounting groove. A connecting rod 10 is fixedly connected to the front side of the telescopic end of the electric push rod 8. A fixing ring 11 is fixedly connected to the upper end of the connecting rod 10. A rotating push plate 12 is rotatably connected inside the fixing ring 11. The rotating push plate 12 has evenly distributed clearance holes inside. The rotating rods 92 are all located in the laterally adjacent clearance holes. The input end of the electric push rod 8 is electrically connected to the output end of the control switch group 2. When the electric push rod 8 is started, the extension of the electric push rod 8... The constricted end extends, pushing the connecting rod 10 to move to the left, causing the fixing ring 11 to move to the left, which in turn causes the rotating push plate 12 to move to the left, pushing the frozen hindquarter meat to the left. Then, the protective door 15 is opened, and the frozen hindquarter meat is taken out. A liquid nitrogen storage tank 3 is fixedly connected to the rear side of the upper surface of the quick-freezing box 1, and a liquid nitrogen pump 4 is fixedly connected to the front side of the upper surface of the quick-freezing box 1. The inlet of the liquid nitrogen pump 4 and the outlet of the liquid nitrogen storage tank 3 are connected by a pipe 13. The outlet of the liquid nitrogen pump 4 is connected to... The two inlets of the diversion tank 6 are connected by pipe 14. The input end of the liquid nitrogen pump 4 is electrically connected to the output end of the control switch group 2. The control switch group 2 is operated to start the liquid nitrogen pump 4. The liquid nitrogen pump 4 draws out the liquid nitrogen inside the liquid nitrogen outlet pipe 3 through pipe 13 and transports it to the diversion tank 6 through pipe 14. The liquid nitrogen is sprayed out to the outer surface of the beef hind part through the nozzle 7. After the liquid nitrogen is sprayed out from the nozzle 7, it absorbs heat when it comes into contact with the air and becomes gaseous nitrogen, thereby rapidly freezing the beef hind part. The system also includes a transmission mechanism 9.

[0022] Transmission mechanism 9 includes a turntable 91, rotating rods 92, gears 93, and an internal gear ring 94. The turntable 91 is rotatably connected to the inner right surface of the quick-freezing box 1. Rotating rods 92 are evenly distributed and rotatably connected inside the turntable 91.

The input end of the motor 5 is electrically connected to the output end of the control switch group 2. Open the protective door 15, insert the beef from the hindquarters onto the outer surface of the rotating rod 92 (the left end of the rotating rod 92 is conical), close the protective door 14, operate the control switch group 2, start the motor 5, the output shaft of the motor 5 rotates, driving the turntable 91 to rotate, driving the rotating rod 92 to rotate around the central axis of the turntable 91, driving the gear 93 to rotate around the central axis of the turntable 91. Since the internal gear ring 94 is fixed, the gear 93 rotates on its own axis while rotating around the central axis of the turntable 91, driving the rotating rod 92 to rotate, so that the beef from the hindquarters rotates on its own axis while rotating around the central axis of the turntable 91.

[0023] The working principle of the rapid freezing device for hindquarters of cattle provided by this utility model is as follows: When using this rapid freezing device to quickly freeze beef hindquarters, open the protective door 15, insert the beef hindquarters into the outer surface of the rotating rod 92 (the left end of the rotating rod 92 is conical), close the protective door 14, operate the control switch group 2, start the motor 5, the output shaft of the motor 5 rotates, driving the turntable 91 to rotate, driving the rotating rod 92 to rotate around the central axis of the turntable 91, driving the gear 93 to rotate around the central axis of the turntable 91. Since the internal gear ring 94 is fixed, the gear 93 rotates on its own axis while rotating around the central axis of the turntable 91, driving the rotating rod 92 to rotate, so that the beef hindquarters rotates around the central axis of the turntable 91. Rotate the machine, operate the control switch group 2, start the liquid nitrogen pump 4, the liquid nitrogen pump 4 draws the liquid nitrogen inside the liquid nitrogen outlet pipe 3 through pipe 13 and transports it to the diversion tank 6 through pipe 2 14, and sprays the liquid nitrogen onto the outer surface of the beef hind part through the nozzle 7. After the liquid nitrogen is sprayed from the nozzle 7, it absorbs heat when it comes into contact with the air and turns into gaseous nitrogen, which then rapidly freezes the beef hind part. After freezing is completed, operate the control switch 2 to turn off the liquid nitrogen pump 4 and the motor 5, start the electric push rod 8, the telescopic end of the electric push rod 8 extends, pushes the connecting rod 10 to move to the left, drives the fixed ring 11 to move to the left, drives the rotating push plate 12 to move to the left, pushes the frozen beef hind part to move to the left, and then opens the protective door 15 to take out the frozen beef hind part.
