Description

Technical Field

[0001] The utility model relates to the field of aquatic product thawing devices, in particular to a frozen aquatic product rapid thawing device for inspection. Background Art

[0002] When inspecting frozen aquatic products, the products must be thawed before the meat can be touched. At present, the common thawing method is to put the frozen aquatic products into water to heat and thaw or to blow hot air on the aquatic products to thaw. Both of these thawing methods have defects. The former will damage the meat if the water temperature is not well controlled. The latter keeps the aquatic products still and the ice cannot be separated from the meat quickly, so the thawing speed is slow. This is a common technical problem in existing thawing devices and is also a problem that technical personnel in this field urgently need to solve.

[0003] In order to solve the above problems, we propose a rapid thawing device for frozen aquatic products for inspection, so as to achieve rapid thawing without damaging the meat quality, and improve the shortcomings of the existing technology. Utility Model Content

[0010] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0011] First, a driving motor is arranged on the side of the thawing box, and the driving motor is used to rotate the net cage, so that the aquatic products inside the net cage can roll, which helps to collide with each other and break the ice wrapped on the aquatic products. At the same time, the ice cubes can also fall, reducing the ice wrapped on the aquatic products, thereby improving the thawing efficiency; second, a heating box and a filter box are arranged between the air inlet pipe and the air supply pipe, and the electric heating pipe is used to heat the air supplied, and it has the function of blowing hot air to thaw.

[0016] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0017] Example

[0018] like Figure 1-2 As shown, a device for fast thawing of frozen aquatic products for inspection comprises a thawing box 1, which forms a sealed space and preserves heat. A bottom sealing plate 14 is arranged at the opening at the bottom of the thawing box 1, and the bottom sealing plate 14 is fixed to the bottom of the thawing box 1 by a latch. The structural design is convenient for disassembly and assembly, and is convenient for rapid sealing and unloading. A cubic net box 2 is arranged inside the thawing box 1 for placing frozen aquatic products for thawing. Rotating rods 3 are fixed at the centers of both ends of the net box 2, and the rotating rods 3 are connected to the inner walls of both sides of the thawing box 1 through bearings. A driving motor 4 and a heating box 5 are also fixed on the outer side of the thawing box 1. The output shaft of the driving motor 4 is connected to the protruding end of one of the rotating rods 3, and can rotate with the net box 2 to turn over the aquatic products inside it, and crush ice cubes by mutual collision and breaking, thereby accelerating the melting speed of ice cubes. A filtering box 6 is arranged on the inner side of the bottom of the heating box 5, and a heat insulation board 7 fixed to the inner wall of the heating box 5 is arranged above the filtering box 6. A plurality of The electric heating tube 8 and the heating box 5 are also fixed with a heat pipe 9 for heating the air or clean water supplied, which is helpful for heating and thawing. One end of the heat pipe 9 is connected to the air supply pipe 11, and the other end of the heat pipe 9 is connected to the filter box 6, and the filter box 6 is provided with activated carbon particles 17 for filtering the odor in the air and water. The two ends of the filter box 6 are fixed with isolation mesh plates 15 inside, and the activated carbon particles 17 are filled between the two isolation mesh plates 15. A sponge block 16 is placed in the space between the two sides of the heating box 5 for filtering particulate impurities. An air inlet pipe 10 is also connected to the filter box 6, and the outer end of the air inlet pipe 10 extends to the outside of the heating box 5. An air supply pipe 11 extends to the inside of the thawing box 1, and a plurality of nozzles 12 are connected to the bottom of the air supply pipe 11 for blowing hot air or spraying hot water over a large area. A PLC controller 13 is fixed on the support plate below the heating box 5, and the PLC controller 13 is electrically connected to the drive motor 4 and the electric heating tube 8 to facilitate the normal operation of the control device.

[0019] The principle and advantages of the utility model are as follows: the PLC controller 13 is powered on, the air pump is sealed and connected to the outer end of the air inlet pipe 10, the heating temperature of the electric heating pipe 8 is set, the electric heating pipe 8 is turned on to heat the heat conducting pipe 9, the sealing plates at the upper openings of the thawing box 1 and the net box 2 are opened, the frozen aquatic products are placed in the net box 2, and the sealing plates on the net box 2 and the thawing box 1 are closed respectively, and then the air pump is turned on to send air into the air inlet pipe 10, the air passes through the sponge block 16 in the filter box 6 to filter out the particulate impurities, and the air is adsorbed and filtered by the activated carbon particles. The air is purified, and the filtered air enters the heat pipe 9. The electric heating tube 8 continues to heat and heats the heat pipe 9. When the air flows through the heat pipe 9, it takes away the heat and becomes hot air. The hot air then enters the nozzle 12 through the air delivery pipe 11 and is finally sprayed out by the nozzle 12. The hot air is blown on the ice wrapped in the aquatic products, and the hot air is used to melt the ice for thawing. The water pump can also be connected to the air inlet pipe 10 to spray water into the thawing box 1. The clean water passes through the air and the sponge block 16 in the filter box 6 to filter out the particulate impurities. The activated carbon particles absorb and filter out the impurities. The clean water will take away the heat through the heated heat conducting pipe 9 and become hot water. The hot water will be sprayed on the ice wrapped in the aquatic product through the nozzle 12, and the hot water will be used to melt the ice to thaw. Since the hot water is sprayed on the aquatic product, a certain part will not be steamed for a long time, so the meat quality can be avoided from being damaged by steaming. During the thawing process, the driving motor 4 is turned on to rotate the net box 2, and the ice wrapped on the aquatic product collides with each other. The ice can fall off from the aquatic product after breaking, shortening the time of melting the ice, and also facilitating the hot air or hot water to evenly contact each part. A piece of aquatic product, further improving the thawing efficiency, the water generated by thawing flows out from the drain pipe on the bottom sealing plate 14, after the thawing is completed, the sealing plate on the net box 2 is turned to the bottom, the bottom sealing plate 14 is removed, the sealing plate on the net box 2 is opened, and the thawed aquatic product falls from the opening of the net box. Compared with the existing thawing method, the aquatic product fast thawing device using this structural design can achieve fast thawing without damaging the meat quality. Improvements are made to the defects in the existing technology so that it can meet the requirements of aquatic product thawing inspection, thereby improving practicality.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
