Abstract
Description
Technical Field
[0001] This utility model relates to the field of meat product processing technology, specifically to a thawing device for meat product processing. Background Technology
[0002] Thawing is a crucial step in meat processing, as its effectiveness directly impacts product quality and the smooth progress of subsequent processing steps. Traditional thawing methods mainly include natural thawing and water thawing. Water thawing is relatively faster. A common thawing method involves adding salt to cold water, stirring well, placing the meat to be thawed in the water, letting it stand for a period of time, then removing it, washing it, and proceeding to the next processing step.
[0003] The existing technology has the following problems: It is generally recommended that the water temperature be controlled between 10℃ and 20℃ for water thawing. During the thawing of meat products in still water, the locally supercooled water will increase in density and flow downwards due to the principle of thermal expansion and contraction, causing the water temperature at the bottom of the container to drop first. After the water temperature drops, the thawing effect on the meat products will be worse. Therefore, it is necessary to maintain the water thawing temperature within the optimal range and accelerate the water flow to speed up the water thawing effect on the meat products. Utility Model Content
[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a thawing device for meat processing, which can effectively solve the problem that the thawing effect of water placed in the existing technology weakens as the temperature decreases.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

The thermometer is electrically connected to the microwave heater. A tray is slidably connected to the inner wall of the water tank, and a water-permeable hole is opened on the inner wall of the tray. An exhaust fan is fixedly mounted on the upper surface of the workbench, and an air heater is fixedly mounted on the upper surface of the workbench. The exhaust fan is connected to the air heater through a pipe, and the air heater is connected to the exhaust hole through an internal pipe.
[0007] Preferably, a telescopic pole is fixedly installed at the lower part of the water tank, the output shaft of the telescopic pole passes through the inner wall of the water tank and is fixedly connected to the bottom of the tray, and a tank cover is provided at the upper end of the workbench.
[0008] Preferably, a water pump is fixedly installed on the upper part of the workbench, and a water inlet pipe is fixedly installed at the output end of the water pump. The other end of the water inlet pipe is connected to the upper part of the water tank, and a water outlet pipe is connected to the lower part of the water tank.
[0009] Preferably, a water tank is fixedly installed on one side of the workbench, the pipe at the input end of the water pump is inserted into the inner groove of the water tank, and the port of the outlet pipe is located at the upper part of the water tank.
[0010] Preferably, a lifting column is fixedly installed on the upper surface of the workbench, a lifting beam is rotatably connected to the top of the lifting column, a hook is fixedly connected to the bottom of one end of the lifting beam, and correspondingly, a lifting ring matching the hook is fixedly connected to the upper end of the can lid.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art:
[0013] 1. This utility model achieves simultaneous internal and external thawing of meat products by setting up a microwave heater and blowing hot air heated by an air heater out from the exhaust port. The hot air released from the exhaust port forms hot bubbles that can cause the still water to tumble and flow, greatly improving the thawing efficiency. By using a thermometer to control the power of the microwave heater, the thawing temperature of the water in the tank can be precisely controlled, avoiding the reduction of the thawing effect of the meat products due to low temperature.
[0014] 2. This utility model uses hooks to lift the rings and move the lid away from the water tank, thus preventing the water tank from being sealed. This prevents excessive heat radiation from leaking out during microwave heating. At the same time, the rising of the water holes makes it easier for workers to remove the thawed meat products after they have been thawed. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] The present invention will be further described below with reference to the embodiments.
[0024] Example:
[0025] Reference Figures 1 to 5A thawing device for meat processing includes a workbench 1, a water tank 2 fixedly mounted on the top of the workbench 1, a turntable 12 rotatably connected to the lower end of the water tank 2, a pulsator 3 fixedly mounted on the upper surface of the turntable 12, and an exhaust vent 10 on the upper surface of the pulsator 3. A microwave heater 4 fixedly mounted on the upper surface of the water tank 2 generates microwaves of a specific frequency. When the microwaves penetrate the meat product, they cause the water molecules inside the meat product to vibrate rapidly, generating heat through friction between the water molecules, thereby accelerating the thawing process of the meat product from the inside. A thermometer 5 fixedly mounted on the upper surface of the water tank 2 is electrically connected to the microwave heater 4. A tray 6 is slidably connected to the inner wall of the water tank 2, and a water permeable hole 7 is provided on the inner wall of the tray 6. An exhaust fan 8 is fixedly installed on the upper surface of workbench 1, and an air heater 9 is fixedly installed on the upper surface of workbench 1. The exhaust fan 8 and the air heater 9 are connected by a pipe. The air heater 9 is connected to the exhaust port 10 through an internal pipe. The exhaust port 10 discharges hot air that has passed through the air heater 9, which can accelerate the rolling and flow of water in the tank and facilitate the dissipation of local cold water. A telescopic pole 11 is fixedly installed at the lower part of the water tank 2. The output shaft of the telescopic pole 11 passes through the inner wall of the water tank 2 and is fixedly connected to the bottom of the tray 6. A can lid 13 is installed at the upper end of workbench 1. By setting the height of the tray 6, the thawed meat products will not be at the bottom of the can, which makes it easier for workers to take out the thawed meat without having to reach deep into the can.
[0026] A water pump 14 is fixedly installed on the upper part of the workbench 1. A water inlet pipe 15 is fixedly installed at the output end of the water pump 14. The other end of the water inlet pipe 15 is connected to the upper part of the water tank 2. A water outlet pipe 16 is connected to the lower part of the water tank 2. Water for thawing is added to the tank through the water supply system. Excess water can be discharged, which is conducive to the circulation and flow of water. A water tank 17 is fixedly installed on one side of the workbench 1. The pipe at the input end of the water pump 14 is inserted into the inner groove of the water tank 17. The port of the water outlet pipe 16 is located at the upper part of the water tank 17. A lifting column 18 is fixedly installed on the upper surface of the workbench 1. A lifting beam 19 is rotatably connected to the top of the lifting column 18. A hook 20 is fixedly connected to the bottom of one end of the lifting beam 19. Correspondingly, a lifting ring 21 matching the hook 20 is fixedly connected to the upper end of the can lid 13. The hook 20 is used to lift the can lid 13 after thawing, so that the staff can take out the thawed meat products from the can without manual handling.
[0027] A motor 22 is fixedly installed at the bottom of the workbench 1. A first traction wheel 23 is fixedly installed on the output shaft of the motor 22. A second traction wheel 25 is rotatably connected to the bottom of the workbench 1. A belt 24 is driven to the inner surface of the first traction wheel 23. The inner surface of the belt 24 is driven to the second traction wheel 25. An external gear 26 is fixedly installed on the top of the second traction wheel 25. The outer surface of the external gear 26 meshes with the external gear 26 at the lower end of the turntable 12. The belt 24 transmits the power of the motor 22 to the turntable 12, thus achieving the meshing connection of the external gear 26 at the lower end of the turntable 12. The rotation of the turntable 12, driven by the mechanical structure of the belt 24 and the external gear 26, ensures a reliable movement of the large-diameter turntable 12.
[0028] The working principle of this utility model is as follows:
[0029] S1, before the frozen meat products are thawed, the lifting column 18 is lowered and the hook 20 hangs the can lid 13 and then the height is raised. The lifting beam 19 rotates to make it easy for the staff to put the meat products to be thawed into the can without moving the can lid 13.
[0030] S2, the output end of the water pump 14 is fixedly installed with a water inlet pipe 15, which injects a large amount of water into the water tank 2. The lifting column 18 and the hanging beam 19 are adjusted to allow the tank cover 13 on the hook 20 to return to its original position. During the water injection process, if the thermometer 5 detects that the water temperature is not between 10°C and 20°C, the thermometer 5 will control the microwave heater 4 to generate microwaves of a specific frequency, which will cause the water molecules inside the meat products to vibrate rapidly, and the water in the tank will also be heated, realizing the simultaneous thawing of the meat products from the inside out. After reaching the preset temperature, the hot air released from the vent 10 forms hot bubbles that can cause the still water to tumble and flow, keeping the water tank 2 at the optimal temperature for water thawing and accelerating the flow of water to speed up the thawing of the meat products.
[0031] S3. In order to prevent the meat pieces from clumping together after thawing and failing to separate, the motor 22 drives the large-diameter turntable 12 to rotate at low speed through mechanical structures such as the belt 24 and the external gear 26. Therefore, after the meat pieces are separated, the parts of the meat pieces that have not yet come into contact with water can also come into contact with warm water to thaw.
[0032] S4, hook 20 hangs the can lid 13 again and raises the height, tray 6 is raised so that the thawed meat products will not be at the bottom of the can, which makes it easier for workers to take out the thawed meat without having to grab it from deep inside the can.
[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
