Aquatic product quality maintaining system and method

Abstract

The invention discloses an aquatic product quality maintaining system and method and aims to solve the problems that protein denaturation is likely to happen during refrigeration of aquatic products,the nutritional value is reduced, all the aquatic products are likely to be frozen to form a whole part, and delivery from a storehouse and transportation of the aquatic products are not facilitated.The system comprises a dewatering mechanism, a freezing box and a refrigerating mechanism, wherein the dewatering mechanism is used for dewatering the aquatic products; a vibrating plate in the freezing box vibrates up and down, so that the aquatic products on the vibrating plate slide downward while being vibrated, and the aquatic products are quickly frozen and cannot be frozen together in the freezing box. The aquatic products slide from the vibrating plate to a feeding hole and then enter a refrigerating warehouse for storage. The aquatic products circularly pass through a normal-temperature zone, a low-temperature zone, an electric field zone and an ultra-low-temperature zone, the temperature of each position in the refrigerating warehouse is more uniform, and improvement of the refrigerating effect is facilitated; alternating current is applied to an upper electrode plate and a lower electrode plate, so that an alternating electric field is generated between the upper electrode plate and the lower electrode plate to act on the aquatic products, and unfreezing fresh keeping of the aquatic products is realized.

Description

technical field [0001] The invention relates to a fresh-keeping technology for aquatic products, more specifically, it relates to a quality assurance system and method for aquatic products. Background technique [0002] In order to maintain the original quality of aquatic products, it is necessary to refrigerate aquatic products. The commonly used refrigeration temperatures are 0~4℃, -1~-4℃-18~-40℃. The lower the temperature, the longer the preservation time. , but long-term freezing of aquatic products will cause protein denaturation and reduce nutritional value. If the fresh-keeping temperature is high, the fresh-keeping effect will be poor. Moreover, it is easy to make all aquatic products freeze to form a whole during the cold storage process. It is inconvenient to transfer aquatic products when they are out of the warehouse. It is often necessary to knock open the frozen aquatic products. The knocking process is easy to damage aquatic products. Contents of the invent...

AI Technical Summary

Problems solved by technology

[0003] The invention overcomes the disadvantages of protein variability in the refrigeration process of aquatic products, reduces nutritional value, and all aquatic products are easy to freeze to form a whole, which is not conducive to the transfer of aquatic products, and provides a quality assurance system and method for aquatic products , The protein is not easy to denature during the refrigeration process of aquatic products, which ensures the nutritional value, and the aquatic products will not freeze to form a whole, which is convenient for the transfer of aquatic products out of the warehouse, and avoids knocking frozen aquatic products together
