Description

A self-circulating low-temperature fresh-keeping box for aquatic products

technical field

The utility model relates to a fresh-keeping box, in particular to a low-temperature fresh-keeping box for self-circulating aquatic products.

Background technique

After the current aquatic products (especially fish) are caught, most of them are stored and transported in the form of chilled preservation, except for a small amount of them that are transported to the destination by live-keeping ships for sale. And the existing way of adopting chilled preservation for aquatic products is usually in a foam box, one layer of crushed ice and one layer of fish are packed and kept fresh in a whole box. The way of placing one layer of crushed ice and one layer of fish will greatly increase the weight of the box, which is not conducive to handling, and will greatly reduce the utilization rate of the space in the box, and when taking out aquatic products from the box, it is necessary to remove layers of broken pieces Ice is very inconvenient. In addition, the fish body in the box is in direct contact with the crushed ice, which will damage the surface of the fish body and reduce its sensory quality.

Application publication number CN102951368A, the Chinese patent of application publication date 2013.03.06 discloses a refrigerator for aquatic products, including a box body and a cover body, a circle of card slots is set on the top edge of the box body, and the bottom edge of the cover body is inserted into the card slots It is connected with the box body in a card-type seal; a cooling bag is installed on the bottom surface of the cover body, a window is opened on the top surface of the cover body corresponding to the pocket of the cooling bag, and a sealing cover is provided at the window. Its disadvantage is that the aquatic products in the refrigerator are accumulated in the box body, causing the heat of the aquatic products away from the cooling bag to be quickly absorbed by the cooling bag, thereby greatly reducing the freshness preservation effect; in addition, the effective freshness preservation capacity of the refrigerator is Small.
