A fresh-keeping device based on air pressure preservation and refrigeration

Abstract

The invention discloses a fresh-keeping device based on air pressure preservation and refrigeration. Its structure includes an upper cover and a cold air duct. Under the action of the refrigerator and the cold air duct, the invention blows cold air into the fresh-keeping device to avoid direct contact between ice cubes and fish meat Reduce the breeding of bacteria mixed with fish meat and ice water. Under the action of the temperature-sensitive propulsion device and the pressurized partition, the fresh-keeping space of the cold storage device is reduced. Since the fresh-keeping device is a closed space, the air volume is reduced to enhance the storage capacity of the fresh-keeping device. Air pressure prevents fish cell membranes from cracking, and under the action of the memory metal and the rotating flange, the memory metal deforms when the temperature reaches the standard, providing a power source for the temperature-sensitive propulsion device, and placing the deep-sea fish on the fish container , By supporting the semicircular structure of the anti-slip bumps, the ice water on the fish meat can flow into the water guide hole better, and the arc water guide groove can prevent water accumulation and lead the ice water into the liquid collector, which is better Realize the separation of fish meat and ice water.

Description

technical field [0001] The invention relates to the field of food fresh-keeping, more precisely, it is a fresh-keeping device based on air pressure preservation and refrigeration. Background technique [0002] Seafood, also known as seafood, refers to dishes made from marine animals, including fish, shrimp, shellfish, etc. In the prior art, the freshness of seafood is generally preserved by direct freezing, which seriously affects the taste and taste of seafood. The current technical considerations are not comprehensive and have the following disadvantages: [0003] In the equipment in the prior art, the freshness of seafood is generally preserved by direct freezing. The seafood is put into the fresh-keeping device and the temperature is lowered by directly putting ice cubes into the fresh-keeping device to achieve low-temperature preservation. However, in some deep-sea Regarding the freshness of fish, because deep-sea fish live in the deep sea all the year round, the press...

Problems solved by technology

[0003] In the equipment in the prior art, the freshness of seafood is generally preserved by direct freezing. The seafood is put into the fresh-keeping device and the temperature is lowered by directly putting ice cubes into the fresh-keeping device to achieve low-temperature preservation. However, in some deep-sea Regarding the freshness of fish, because deep-sea fish live in the deep sea all the year round, the pressure is higher than that in the land environment, and the pressure in the fresh-keeping device is lower than that in the deep sea, which makes some fish cells rupture directly, affecting the taste of seafood. And it is kept fresh by direct freezing. The direct contact between ice cubes and fish will seriously affect the taste and texture of seafood.
