A preservative experimental comparison device for improving the shelf life of cold freshness and its application method

Abstract

The invention discloses a preservative experimental comparison device for improving the shelf life of cold freshness and its use method, which comprises a base, a motor, a storage tray, an isolation cover and a spray head. A positioning hole is reserved inside the base, and the motor is inserted into the Installed on the inner wall of the positioning hole, the storage tray is located directly above the rubber pad, an elastic member is fixed between the weighing scale and the storage tray, a positioning plate is installed on the top of the base, and the middle part of the positioning plate is fixed There is a limit rod, the end of the isolation cover is provided with a positioning ring, and the positioning ring is sleeved on the outside of the limit rod, the control rod is connected to a circular plate through the communication pipe through the bearing, and the nozzle is installed on the isolation cover. at the top center. The antistaling agent experimental comparison device for improving the cold-fresh shelf life and the use method thereof facilitate the comparison experiment, reduce the error of the comparison experiment result caused by the external environment and human factors, and make the comparison result 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.
