Description

Technical Field

[0001] The utility model relates to the technical field of food thawing, in particular to a frozen food thawing device. Background Art

[0002] Food safety testing is to detect harmful substances in food according to national indicators, mainly some harmful and toxic indicators, such as heavy metals, aflatoxin, etc. An important aspect of food science and engineering is to introduce and apply chemical unit operations, and develop food engineering unit operations, so as to promote the development of the food industry in the direction of large-scale, continuous and automated. In the process of food testing, refrigerated or frozen foods are often thawed. When food is thawed, as the ice crystals melt, the hydrophilic colloids in the cells absorb water, and water gradually diffuses and penetrates into the cells. When thawing, food should pass through the maximum ice crystal formation zone as soon as possible, and the temperature difference between the inside and outside of the food should be small to avoid recrystallization, which seriously affects the detection of food.

[0003] A frozen food thawing device is disclosed in a Chinese utility model patent with announcement number CN219323143U. By setting up a spray assembly, it is possible to clean the frozen blocks on the surface of the frozen food that have melted but not fallen off, and at the same time avoid secondary crystallization of water on the surface of the frozen food, which helps to improve the thawing efficiency and solves the problem in the prior art that ice crystals condense on the surface of frozen food for a long time during the thawing process, which will hinder the thawing process.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the device increases the temperature of the inner cavity through a heating tube so that the ice crystals on the surface of the frozen food gradually melt, and then sprays water onto the surface of the frozen food so that the ice crystals remaining on the surface of the frozen food fall off. However, when taking the frozen food out of the hanging rack, it is necessary to take the frozen food on the hanging rack one by one, which is rather troublesome and the efficiency of discharging the frozen food is not high.

[0033] The flushing component is used to flush ice crystals off the surface of frozen food. The flushing component includes two pumps 30 installed on the top of the water tank 2. The input end of the pump 30 is connected to the top of the water tank 2, and the pipe connecting the input end of the pump 30 with the water tank 2 extends to the bottom of the inner side of the water tank 2.

[0034] The implementation principle of a frozen food thawing device in the embodiment of the present application is as follows: first open the two box doors 4, then start the motor 8, the motor 8 drives the rotating disk 7 to rotate, when the pressure plate 29 does not abut against the surface of the abutment disk 15, turn off the motor 8, and then hang the frozen food on the slide bar 18. After the hanging of the frozen food is completed, close the two box doors 4, and then start the motor 8 to thaw the frozen food. After thawing is completed, open the box doors 4. When the box doors 4 rotate, they drive the rotating shaft 6 to rotate through the rotating sleeve 5, so that the turntable 20 drives the movable block 23 to move horizontally along the slide rail plate 24 through the support rod 21 and the connecting rod 22. When the movable block 23 moves, it drives the piston rod 25 to move into the air inlet pipe 26, so that the air in the air inlet pipe 26 moves into the sleeve 27, so that the piston pressure rod 2 8 moves downward with the pressure plate 29, so that the pressure plate 29 drops to the same height as the abutment disk 15. Under the action of the motor 8, the abutment disk 15 rotates along the rotating disk 7. During the rotation, the abutment disk 15 is subjected to the abutment force of the pressure plate 29, and the abutment disk 15 moves downward, causing the piston push rod 14 to move toward the inside of the L-shaped tube 13, so that the air in the L-shaped tube 13 pushes the transverse piston rod 16 to move outward, so that the movable plate 17 moves toward the inside of the limiting tube 19 with the sliding rod 18, so that the frozen food loses support and falls into the inside of the receiving box 3 for collection. After all the frozen food falls into the receiving box 3, the motor 8 is turned off and the receiving box 3 is pulled out, thereby realizing automatic collection of the frozen food when the box door 4 is opened, thereby improving the discharge efficiency of the device.

[0035] To defrost the frozen food, start the motor 8, which will drive the rotating disk 7 to rotate. While the rotating disk 7 revolves with the frozen food, the fixed tube 9 is fixed, so that the fixed gear 10 does not rotate. During the rotation of the rotating disk 7, the transmission gear 11 is subjected to the meshing force of the fixed gear 10, so that the transmission gear 11 itself rotates, thereby causing the frozen food to rotate itself. The heating plate is driven by an external power supply to heat the device, so that the heat flows to the inside of the device through the air outlet, so that the temperature inside the box body 1 increases, and the ice crystals on the surface of the frozen food are melted. Finally, the two pumps 30 are started to transport the water in the water tank 2 to the flushing plate 32 through the L-shaped water pipe 31, and then the surface of the frozen food is flushed through the water outlet nozzle, so that when the device flushes the surface of the frozen food, the flushing effect on the frozen food is more uniform, thereby improving the thawing effect of the device on the frozen food.

[0036] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
