[0014] In one embodiment, a plurality of air inlet grooves are provided at one end of the protective shell side wall adjacent to the condenser protective shell, a plurality of heat dissipation grooves are provided at the lower end of the side wall of the control door, and a plurality of receiving trays are installed on the side wall of the freezing tank.

[0015] The present invention arranges a centrifugal assembly. When the rotating rod rotates, the rotating rod drives the acceleration fan and the centrifugal shell to rotate. The rotation of the centrifugal shell drives the aquatic product to rotate, so that water droplets attached to the aquatic product are splashed on the inner wall of the centrifugal shell under the action of centrifugal force. The water droplets flow on the inner wall of the centrifugal shell and finally pass through a plurality of centrifugal grooves and splash on the side wall of the collecting plate. After the collecting plate collects the water droplets, the water droplets are finally collected at the bottom of the collecting plate under the action of gravity to form discharged water, so that the water droplets in the aquatic product can be released, thereby preventing the water droplets attached to the aquatic product from forming larger ice crystals. The ice crystals may destroy the cell structure of the aquatic product during the formation and melting process, resulting in water loss after thawing and poor taste. After the water droplets in the aquatic product are released, the growth of bacteria can be reduced. Water is one of the important conditions for the growth and reproduction of microorganisms such as bacteria. The water content of the dried aquatic product is reduced, which is not conducive to the survival and reproduction of microorganisms. The shelf life can be extended to a certain extent, and the freshness and quality of the aquatic product can be maintained.

[0016] By setting an acceleration fan, when the rotating rod rotates, the acceleration fan rotates with the rotating rod, and the acceleration fan rotates to blow out the acceleration airflow F1 downward, which is used to accelerate the freezing of aquatic products to maintain the freshness of aquatic products, extend the shelf life, and reduce the formation of ice crystals. At the same time, when rotating, the aquatic products will adhere to the inner wall of the centrifugal shell under the action of centrifugal force, thereby increasing the surface area of ​​the aquatic products in contact with the acceleration airflow F1, further accelerating the freezing of aquatic products to maintain the freshness of aquatic products, extend the shelf life, and reduce the formation of ice crystals. Multiple air inlet slots can supplement the pressure of the centrifugal shell.

[0017] By setting an acceleration fan, the accelerating airflow F1 accelerates the freezing of the aquatic product and then enters the collecting plate through multiple centrifugal grooves. Part of the accelerating airflow F1 flows out from the gap between the collecting plate and the centrifugal shell, and the other part of the accelerating airflow F1 enters the guide tube to form a cooling airflow F2. Because the height of the side of the bottom of the collecting plate adjacent to the guide tube gradually increases toward the side of the bottom of the collecting plate away from the guide tube, so that the discharge water accumulated at the bottom of the collecting plate will enter the guide tube, the cooling airflow F2 can accelerate the discharge water to enter the collecting plate, so as to prevent the discharge water from remaining in the collecting plate, and then the residual water will exist in the freezing tank for a long time to cause odor; the collecting plate can collect the condensed water generated by the evaporating device, and the cooling airflow F2 can also cool the condensed water and discharge water collected in the collecting plate, and then cool the condensing tube.

[0018] By setting the electric bottom hinged door, after the rotating rod runs to the set time of the control box, the two electric bottom hinged doors will flip down and open, so that the aquatic products with a certain degree of freezing will fall onto the receiving tray located directly below the collecting member. The receiving tray is used to collect the dehydrated aquatic products. The aquatic products with a certain degree of freezing can prevent the aquatic product body from directly sticking to the receiving tray, thereby preventing the aquatic products from being damaged when they are taken out. After the aquatic products fall onto the receiving tray, the two electric bottom hinged doors will resume flipping upward and closing. After the aquatic products are put into the centrifugal housing through the feed door, the moisture of the aquatic products will gather at the bottom of the two electric bottom hinged doors, and the moisture will enter the water storage tank of the collecting member through multiple water inlet tanks and water diversion tanks. When the water storage tank is collected to a certain extent, the collecting member can be pulled out from the bottom of the rotating rod to clean the collecting member.

[0019] By setting the electric bottom hinged door, when the two electric bottom hinged doors are flipped downward and opened, the rotating rod will stop rotating, and the accelerated airflow F1 is used to accelerate the freezing of the aquatic product. When the surface of the aquatic product is frozen to a certain extent, the weight of the aquatic product increases, and the two semi-funnel-shaped electric bottom hinged doors form a funnel shape, so that the weight of the aquatic product is more concentrated in the middle of the funnel shape, that is, the bottom of the electric bottom hinged door. At the same time, under the impact of the accelerated airflow F1, the surface of the aquatic product is frozen to a certain extent, and the weight of the aquatic product increases. The two electric bottom hinged doors will flip downward and open in advance to stop the operation of the rotating rod and reduce power loss. At the same time, after the aquatic product falls onto the receiving plate, the two electric bottom hinged doors will resume flipping upward and closing.

[0020] By setting up an acceleration fan, the cooling airflow F2 can also cool the condensed water and drain water collected in the collection tray, and then cool the condenser. The cooled condensed water and drain water flow out through the discharge pipe into the condenser casing to cool the condenser, thereby accelerating the cooling of the refrigerant inside the condenser and accelerating the freezing efficiency of the refrigeration equipment. At the same time, the cooling fan can discharge the condensed water and drain water out of the refrigeration equipment through multiple heat dissipation slots.

[0021] The present invention has a simple structure and can effectively dehydrate aquatic products to prevent water droplets attached to aquatic products from forming large ice crystals. Ice crystals may destroy the cell structure of aquatic products during the formation and melting process, resulting in water loss after thawing and poor taste. After the water droplets in the aquatic products are removed, bacterial growth can be reduced. Water is one of the important conditions for the growth and reproduction of microorganisms such as bacteria. The water content of the dried aquatic products is reduced, which is not conducive to the survival and reproduction of microorganisms. It can extend the shelf life to a certain extent and maintain the freshness and quality of the aquatic products. At the same time, the freezing equipment can also accelerate the freezing of aquatic products to maintain the freshness of the aquatic products, extend the shelf life, and reduce the formation of ice crystals.

The water content of the aquatic product after drying is reduced, which is not conducive to the survival and reproduction of microorganisms. It can extend the shelf life to a certain extent and maintain the freshness and quality of the aquatic product.

[0045] 2. When the rotating rod 210 rotates, the accelerating fan 212 rotates with the rotating rod 210, and the accelerating fan 212 rotates to blow out the accelerating airflow F1 downward, which is used to accelerate the freezing of aquatic products to maintain the freshness of the aquatic products, extend the shelf life, and reduce the formation of ice crystals. At the same time, when the aquatic products rotate, the aquatic products adhere to the inner wall of the centrifugal housing 211 under the action of centrifugal force, thereby increasing the surface area of ​​the aquatic products contacted by the accelerating airflow F1, further accelerating the freezing of the aquatic products to maintain the freshness of the aquatic products, extend the shelf life, and reduce the formation of ice crystals. Multiple air inlet slots 219 can supplement the pressure of the centrifugal housing 211.

[0046] 3. The accelerated airflow F1 accelerates the freezing of the aquatic product and then enters the collecting plate 32 through multiple centrifugal grooves 216. Part of the accelerated airflow F1 flows out from the gap between the collecting plate 32 and the centrifugal housing 211, and the other part of the accelerated airflow F1 enters the guide tube 33 to form a cooling airflow F2. Because the height of the side of the bottom of the collecting plate 32 adjacent to the guide tube 33 gradually increases toward the side of the bottom of the collecting plate 32 away from the guide tube 33, so that the discharged water accumulated at the bottom of the collecting plate 32 will enter the guide tube 33, the cooling airflow F2 can accelerate the discharged water to enter the collecting tray 620, so as to prevent the discharged water from remaining in the collecting plate 32, and then the residual water will exist in the freezing tank 15 for a long time to cause odor; the collecting plate 32 can collect the condensed water generated by the evaporating device 63, and the cooling airflow F2 can also cool the condensed water and discharged water collected in the collecting tray 620, and then cool the condensing tube 53.

[0047] 4. After the rotating rod 210 runs to the set time of the control box 16, the two electric bottom hinged doors 214 will flip downward and open, so that the aquatic products with a certain degree of freezing will fall onto the receiving tray 150 located directly below the collecting member 22. The receiving tray 150 is used to collect the dehydrated aquatic products. The aquatic products with a certain degree of freezing can prevent the aquatic products from directly sticking to the receiving tray 150, thereby preventing the aquatic products from being damaged when they are taken out. After the aquatic products fall onto the receiving tray 150, the two electric bottom hinged doors 214 will resume flipping upward and closing. After the aquatic product is put into the centrifugal housing 211 through the feed gate 213, the moisture of the aquatic product will gather at the bottom of the two electric bottom hinged doors 214, and the moisture will enter the water storage tank 220 of the collecting member 22 through multiple water inlet grooves 218 and water diversion grooves 217. When the water storage tank 220 collects to a certain extent, the collecting member 22 can be pulled out from the bottom of the rotating rod 210, and then the collecting member 22 can be cleaned.

[0048] 5. When the two electric bottom hinged doors 214 are flipped downward and opened, the rotating rod 210 will stop rotating, and the accelerated airflow F1 is used to accelerate the freezing of the aquatic product. When the surface of the aquatic product is frozen to a certain extent, the weight of the aquatic product increases, and the two semi-funnel-shaped electric bottom hinged doors 214 form a funnel shape, so that the weight of the aquatic product is more concentrated in the middle of the funnel shape, that is, the bottom of the electric bottom hinged door 214. At the same time, under the impact of the accelerated airflow F1, the surface of the aquatic product is frozen to a certain extent, and the weight of the aquatic product increases. The two electric bottom hinged doors 214 will flip downward and open in advance to stop the operation of the rotating rod 210 and reduce power loss. At the same time, after the aquatic product falls onto the receiving tray 150, the two electric bottom hinged doors 214 will resume flipping upward and closing.

[0049] 6. After the control box 16 is started, the compressor 43 is operated, and the refrigerant circulates between the compressor 43, the liquid outlet capillary 45, the heat absorption tube 631, and the condenser 53. The refrigerant gas is compressed through the mechanical movement inside the compressor 43, so that its pressure and temperature rise sharply, and it becomes a high-temperature and high-pressure refrigerant gas. The high-temperature and high-pressure refrigerant gas enters the liquid outlet capillary 45. The high-temperature and high-pressure refrigerant gas produces a throttling and cooling effect through the liquid outlet capillary 45, so that its pressure and temperature drop rapidly, and it becomes a low-temperature and low-pressure refrigerant liquid. The refrigerant liquid enters the evaporation device 63 after passing through the liquid outlet capillary 45. The refrigerant liquid evaporates rapidly in the evaporation device 63, absorbs a large amount of heat from the surrounding environment, and reduces the air temperature around the evaporation device 63. The evaporated high-temperature and high-pressure refrigerant gas returns to the compressor 43 through the liquid inlet pipe 44 after being cooled by the condenser 53, thereby repeatedly cooling the aquatic products.

[0050] 7. The circulating fan 64 can not only accelerate the cooling of the evaporation device 63, improve the heat absorption efficiency of the evaporation device 63, and allow the temperature in the refrigeration equipment to drop to the set value more quickly, which is conducive to the rapid freezing of aquatic products; it can also accelerate the air flow speed on the surface of the evaporation device 63, so that the frost layer on the surface of the evaporation device 63 can accelerate the sublimation speed at low temperature and reduce the accumulation of the frost layer; at the same time, the flowing air can also make the frost layer more evenly distributed and thinner, reduce the frost layer The obstacle to the heat transfer of the evaporation device 63 is reduced, and the evaporation device 63 maintains a good refrigeration performance. The cooling airflow F2 can also cool the condensed water and the drained water collected in the collection tray 620, and then cool the condenser 53. The cooled condensed water and the drained water flow out through the discharge pipe 621 to the condenser protective shell 51 for cooling the condenser 53, thereby accelerating the cooling of the refrigerant in the condenser 53 and accelerating the freezing efficiency of the refrigeration equipment; at the same time, the cooling fan 52 can discharge the condensed water and the drained water out of the refrigeration equipment through a plurality of heat dissipation slots 121. The heating support plate 630 can be started after the freezer door 18 is opened to heat the surface of the heat absorption tube 631 to prevent frost from condensing on the surface of the heat absorption tube 631, thereby affecting the heat absorption efficiency of the heat absorption tube 631 and reducing the refrigeration effect of the refrigeration equipment.

[0051] The present invention provides a centrifugal assembly 21. When the rotating rod 210 rotates, the rotating rod 210 drives the acceleration fan 212 and the centrifugal housing 211 to rotate. The rotation of the centrifugal housing 211 drives the aquatic product to rotate, so that the water droplets attached to the aquatic product splash on the inner wall of the centrifugal housing 211 under the action of centrifugal force. The water droplets flow on the inner wall of the centrifugal housing 211 and finally pass through a plurality of centrifugal grooves 216 and splash on the side wall of the collecting plate 32. After the collecting plate 32 collects the water droplets, the water droplets are finally collected at the bottom of the collecting plate 32 under the action of gravity to form discharged water, so that the water droplets in the aquatic product can escape, thereby preventing the water droplets attached to the aquatic product from forming larger ice crystals. The ice crystals may destroy the cell structure of the aquatic product during the formation and melting process, resulting in water loss after thawing and poor taste. After the water droplets in the aquatic product escape, the growth of bacteria can be reduced. Water is one of the important conditions for the growth and reproduction of microorganisms such as bacteria. The water content of the dried aquatic product is reduced, which is not conducive to the survival and reproduction of microorganisms. The shelf life can be extended to a certain extent to maintain the freshness and quality of the aquatic product.

[0052] By setting the acceleration fan 212, when the rotating rod 210 rotates, the acceleration fan 212 rotates with the rotating rod 210, and the acceleration fan 212 rotates and blows out the acceleration airflow F1 downward, and the acceleration airflow F1 is used to accelerate the freezing of the aquatic product to maintain the freshness of the aquatic product, extend the shelf life, and reduce the formation of ice crystals. At the same time, when the aquatic product rotates, the aquatic product adheres to the inner wall of the centrifugal housing 211 under the action of centrifugal force, thereby increasing the surface area of ​​the aquatic product contacted by the acceleration airflow F1, further accelerating the freezing of the aquatic product to maintain the freshness of the aquatic product, extend the shelf life, and reduce the formation of ice crystals. Multiple air inlet slots 219 can supplement the pressure of the centrifugal housing 211.

[0053] By setting an acceleration fan 212, the accelerated airflow F1 accelerates the freezing of the aquatic product and then enters the collecting plate 32 through multiple centrifugal grooves 216. Part of the accelerated airflow F1 flows out from the gap between the collecting plate 32 and the centrifugal housing 211, and the other part of the accelerated airflow F1 enters the guide pipe 33 to form a cooling airflow F2. Because the height of the side of the bottom of the collecting plate 32 adjacent to the guide pipe 33 gradually increases toward the side of the bottom of the collecting plate 32 away from the guide pipe 33, so that the discharge water accumulated at the bottom of the collecting plate 32 will enter the guide pipe 33, the cooling airflow F2 can accelerate the discharge water to enter the collecting tray 620, so as to prevent the discharge water from remaining in the collecting plate 32, and then the residual water will exist in the freezing tank 15 for a long time to cause odor; the collecting plate 32 can collect the condensed water generated by the evaporating device 63, and the cooling airflow F2 can also cool the condensed water and discharge water collected in the collecting tray 620, and then cool the condensing tube 53.

[0054] By setting the electric bottom hinged doors 214, after the rotating rod 210 runs to the set time of the control box 16, the two electric bottom hinged doors 214 will flip open downwards, so that the aquatic products with a certain degree of freezing will fall onto the receiving tray 150 located directly below the collecting member 22. The receiving tray 150 is used to collect the dehydrated aquatic products. The aquatic products with a certain degree of freezing can prevent the aquatic products from directly sticking to the receiving tray 150, thereby preventing the aquatic products from being damaged when they are taken out. After the aquatic products fall onto the receiving tray 150, the two electric bottom hinged doors 214 will resume flipping upwards and closing. After the aquatic product is put into the centrifugal housing 211 through the feed gate 213, the moisture of the aquatic product will gather at the bottom of the two electric bottom hinged doors 214, and the moisture will enter the water storage tank 220 of the collecting member 22 through multiple water inlet grooves 218 and water diversion grooves 217. When the water storage tank 220 collects to a certain extent, the collecting member 22 can be pulled out from the bottom of the rotating rod 210, and then the collecting member 22 can be cleaned.

[0055] By setting the electric bottom hinged door 214, when the two electric bottom hinged doors 214 are flipped downward and opened, the rotating rod 210 will stop rotating, and the accelerated airflow F1 is used to accelerate the freezing of the aquatic product. When the surface of the aquatic product is frozen to a certain extent, the weight of the aquatic product increases, and the two semi-funnel-shaped electric bottom hinged doors 214 form a funnel shape, so that the weight of the aquatic product is more concentrated in the middle of the funnel shape, that is, the bottom of the electric bottom hinged door 214. At the same time, under the impact of the accelerated airflow F1, the surface of the aquatic product is frozen to a certain extent, and the weight of the aquatic product increases. The two electric bottom hinged doors 214 will flip downward and open in advance to stop the operation of the rotating rod 210 and reduce power loss. At the same time, after the aquatic product falls onto the receiving tray 150, the two electric bottom hinged doors 214 will resume flipping upward and closing.

[0056] By setting up the acceleration fan 212, the cooling airflow F2 can also cool the condensed water and discharged water collected in the collection tray 620, and then cool the condenser 53. The cooled condensed water and discharged water flow out through the discharge pipe 621 to the condenser shell 51 for cooling the condenser 53, thereby accelerating the cooling of the refrigerant inside the condenser 53 and accelerating the freezing efficiency of the refrigeration equipment. At the same time, the cooling fan 52 can discharge the condensed water and discharged water out of the refrigeration equipment through multiple heat dissipation slots 121.

[0057] The present invention has a simple structure and can effectively dehydrate aquatic products to prevent water droplets attached to aquatic products from forming large ice crystals. Ice crystals may destroy the cell structure of aquatic products during the formation and melting process, resulting in water loss after thawing and poor taste. After the water droplets in the aquatic products are removed, bacterial growth can be reduced. Water is one of the important conditions for the growth and reproduction of microorganisms such as bacteria. The water content of the dried aquatic products is reduced, which is not conducive to the survival and reproduction of microorganisms. It can extend the shelf life to a certain extent and maintain the freshness and quality of the aquatic products. At the same time, the freezing equipment can also accelerate the freezing of aquatic products to maintain the freshness of the aquatic products, extend the shelf life, and reduce the formation of ice crystals.
