Preservative experiment comparison device for improving cold fresh expiration date, and use method thereof

Abstract

The invention discloses a preservative experiment comparison device for improving a cold fresh expiration date, and a use method thereof. The device comprises a base, a motor, object placement disks,isolation covers and shower nozzles, wherein a positioning hole is reversed in the base; the motor is embedded in the inner wall of the positioning hole; the object placement disks are positioned justabove rubber cushions; elastic elements are fixed between each weighing scale and each object placement disk; the top of the base is provided with a positioning plate; the middle of the positioning plate is fixedly provided with a spacing rod; the end part of each isolation cover is provided with a positioning ring; in addition, the positioning ring is sheathed to the outer side of the spacing rod; the control rod penetrates through a communication pipe through a bearing to be connected with a round plate; and each shower nozzle is installed on the center of the top of each isolation cover. The preservative experiment comparison device for improving the cold fresh expiration date, and the use method thereof are convenient for carrying out a comparison experiment, the errors of the resultsof the comparison experiment due to an external environment and a human factor can be reduced, and the comparison result is more accurate and effective.

Description

technical field [0001] The invention relates to the technical field of cold freshness preservation, in particular to an experimental comparison device for freshness preservation agents for improving the shelf life of cold freshness and its use method. Background technique [0002] Cold freshness preservation technology is an extremely important means for cold freshness preservation. Through cold freshness preservation, it can greatly facilitate the transfer and storage of cold freshness, avoid deterioration of cold freshness during storage and transfer, and maintain cold freshness. The edible and nutritious properties make the long-distance transshipment and transportation operation of cold freshness possible, facilitate the sale of cold freshness, meet the satisfaction of seafood in remote sea areas, increase the sales of seafood, and drive economic development. However, the existing cold freshness preservation technology There are the following problems when using: [000...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a preservative experimental comparison device and its use method to improve the shelf life of cold fresh products, so as to solve the above-mentioned background technology, the structure of the preservative experimental comparison device is complicated, and it is inconvenient to quickly and conveniently check the quality of preservatives. Effective and quick comparison has insufficient practicability, and it is difficult to provide consumers with good and accurate comparative experimental data.
