Fish ice temperature water-free survival keeping transportation device

Abstract

The invention relates to the field of fish survival keeping transportation, in particular to a fish ice temperature water-free survival keeping transportation device. The device comprises a box body, a box cover, an oxygen inflating hole and a fish bed, wherein the box body is in a double-layer structure, the box cover is matched with the box body and is movably connected with the box body, the oxygen inflating hole is positioned at the bottom of the side surface of the box body, and the fish bed is positioned inside the box body and is matched with the box body. The fish ice temperature water-free survival keeping transportation device is characterized in that the fish bed is at least in one layer, the double-layer box body comprises an outer layer box body made of thermal isolation materials and an inner layer box body made of heat insulation materials, the thermal isolation materials are composite materials made of aluminum foils and kraft paper, the heat insulation materials are rock wool, and polystyrene foam plastics are arranged between the outer layer box body and the inner layer box body. The fish ice temperature water-free survival keeping transportation device has the advantages that the structure is simple, convenience and practicability are realized, the survival keeping transportation device is suitable for large-scale industrialized production, the energy consumption is not needed, the cost is reduced, and the survival rate of fish bodies is high.

Description

technical field [0001] The invention relates to the field of fish transportation for keeping alive, in particular to a transportation device for keeping fish alive at ice temperature and without water. Background technique [0002] Fish is one of the most important high-quality animal protein sources for human intake. In recent years, due to the increasingly prominent food safety issues, people have great doubts and worries about freezing fresh fish. Therefore, people's demand for live fish has risen linearly Trend, favored by the majority of consumers. At present, domestic and foreign markets still adopt the traditional method of transporting live fish with water to transport live fish. However, water transportation will lead to deterioration of water quality, such as increased water temperature, increased ammonia nitrogen content, decreased oxygen content, increased carbon dioxide content, and decreased pH value, etc., coupled with the collision between fish bodies and t...

AI Technical Summary

Problems solved by technology

Although this device realizes the transportation of freshwater fish without water, it has the following disadvantages: (1) no fixed fish body device is installed, which will cause the fish body to die due to bumps and collisions during transportation; (2) it is not filled with pure water. Oxygen, although the fish body enters a dormant state, it still needs to breathe oxygen, and the oxygen in the air is far from enough, so the fish will die due to lack of oxygen in a short time; (3) Use inducers and edible alcohol to induce Fish dormant, although alcohol and inducers are non-toxic, they will produce residues in the fish body, and long-term consumption will cause potential harm to the human body; (4) The time of stopping food and temporary breeding is too short, and live fish cannot empty their feces at all. At the same time, If the cooling rate is too fast, it will cause stress to the live fish, thereby shortening the survival time and reducing the survival rate; (5) The production and processing are complicated and the use cost is high, which is not conducive to industrial application;

Although this transport box can carry out live transport in a short time, the transport box has the following disadvantages: (1) The wet sponge layer covers the live fish. Resist and cannot open to breathe and die; (2) The volume in the box is too small and the amount of oxygen is less. If the transportation time is long, the fish will die due to lack of oxygen; (3) The box made of foam material is sealed Poor performance, rapid temperature rise, pure oxygen is easy to leak out of the body
