Sample storage box used for food detection

Abstract

The invention discloses a sample preservation box for food testing, which comprises a box body, the box body is equipped with a vacuum tube, a handle, a box cover and a heat insulation board, a refrigerator room and a heat storage room are arranged in the box body, the refrigerator room and the The thermal storage chamber is equipped with a refrigeration block and an electric heating block respectively. The bottom of the cold storage room and the hot storage room are connected with an installation layer by vertical rails. Test tube racks are installed on both sides of the cold storage room and the thermal storage room. There are several test tube racks in the test tube rack. Placement holes, test tubes are inserted into the test tube placement holes, pipe clamps are provided on the side of the test tube placement holes, straight racks are inserted in the vertical rails, the straight racks are connected with the test tube rack, and gears are installed in the installation layer through the rotating shaft. Meshing with the spur rack, one end of the rotating shaft is fixedly connected with a handle, a variety of food samples can be placed and stored in the storage box, the applicability is wide, the food storage space is well sealed, the quality of food sample preservation is better, and it is more convenient to extract and place food. Food dripping is reduced, the freezer is cleaner, and food preservation is safer.

Description

technical field [0001] The invention relates to the technical field of food testing, in particular to a sample storage box for food testing. Background technique [0002] In recent years, food safety issues caused by factors such as environmental pollution, excessive pesticide and veterinary drug residues, abuse of additives, and improper storage have attracted widespread attention. [0003] Most of the samples for food testing are inhomogeneous. Due to the different maturity, processing and storage conditions, and the influence of the external environment, the same kind of food will have large differences in nutritional components and content as well as the degree of contamination. , the composition and content of different parts will also be different. Food samples are highly variable, and most foods come from animal and plant tissues, which are biologically active cells, and food is a natural medium for microorganisms. During the process of sampling, storage, transporta...

AI Technical Summary

Problems solved by technology

[0005] (1) Existing food preservation boxes can only store one or several foods of low-temperature preservation food or high-temperature preservation food, and there are few types of food preservation. Only one food can be placed in the space, otherwise multiple foods will react or mix together, resulting in inaccurate detection results;

[0006] (2) Existing food storage boxes generally have only one gasket. When the sealed box is opened or items are placed, the air may chemically react with the food in the storage box, resulting in inaccurate food detection;

[0007] (3) Existing food preservation boxes generally have a large depth in order to store more food, so it is very inconvenient to place and extract food samples. Generally, there are lights in the box to see clearly, and because of the need Food samples are easy to fall into the non-preservation space of the box, causing pollution to the box. Another type of storage box with a test tube rack is unstable in the test tube rack. It is easy to make the test tube shake or fall out of the test tube rack, which will affect the preservation of food samples
