AI Technical Summary

Technical Problem

Existing food storage containers lack a condensation treatment mechanism and suffer from temperature imbalance when storing raw red-eyed trout in multiple layers, leading to condensation buildup, spoilage of the raw fish, and increased temperature.

Method used

A food storage box was designed, comprising a low-temperature shelf, a guide groove, a flow channel, a temperature equalization mechanism, and highly absorbent cotton. The flow channel drains condensate, the temperature equalization rod achieves temperature uniformity, and a temperature-sensitive color-changing ink layer monitors the temperature.

Benefits of technology

It effectively prevents sashimi from spoiling due to condensation buildup, achieves uniform refrigeration of multi-layered sashimi, extends the shelf life, and reminds users to replace the refrigerant or consume the sashimi in time through temperature-sensitive color changes.

Abstract

The utility model relates to the technical field of cold storage and preservation boxes for uncooked food, in particular to a low-temperature cold storage and preservation box for uncooked squaliobarbus curriculus products, which comprises a preservation box, a low-temperature laminate is placed at the bottom of the preservation box, placement laminates are sequentially stacked above the low-temperature laminate, guide grooves are symmetrically arranged on the inner walls of two sides of the preservation box, and the guide grooves are communicated with the preservation box. Guide strips matched with the guide grooves are installed on the two sides of the low-temperature layer plate and the two sides of the containing layer plate, flow guide grooves are formed in the bottom wall of the containing layer plate from the center to the two sides, confluence grooves corresponding to the flow guide grooves are formed in the inner walls of the two sides of the preservation box, and refrigerants are placed in the low-temperature layer plate. And a temperature equalizing mechanism for transferring the low temperature of the bottom layer to the top layer is arranged on the low-temperature layer plate. According to the sashimi preservation box, after condensate water is generated due to refrigeration of a refrigerant, the condensate water is converged into the confluence groove through the flow guide groove and flows to the bottom of the preservation box, and the condensate water is absorbed through the high-water-absorption cotton, so that the situation that sashimi on a placement layer plate is soaked and deteriorated due to the fact that the condensate water is silt in the placement layer plate is avoided.
