Fresh-keeping and freezing device for tilapia slices as well as processing method

Abstract

The invention discloses a fresh-keeping and freezing device for tilapia slices. The fresh-keeping and freezing device comprises a machine body, wherein an equipment cavity is formed in the machine body, a freezing mechanism is arranged in the equipment cavity, a freezing cavity is formed in the machine body, a motor cavity and a mounting groove are formed in the side wall of the machine body, a driving motor is installed in the motor cavity, and a threaded rod is vertically installed in the mounting groove. The invention further discloses a fresh-keeping and freezing processing method for thetilapia slices. The method comprises the following steps of S1, pretreating; S2, finishing; S3, methane treating; S4, preservative making; S5, soaking; S6, air drying; and S7, freezing. The fresh-keeping and freezing device for the tilapia slices has the advantages that the structure is ingenious, the use is facilitated, the tilapia slices can be effectively kept fresh, and the taste of the tilapia slices is ensured on the premise that the shelf life is ensured. The fresh-keeping and freezing processing method for the tilapia slices has the advantages that the raw material cost is low, and thefresh-keeping period time is prolonged on the premise that the food safety is ensured.

Description

technical field [0001] The invention relates to the technical field of food preservation, in particular to a fresh-keeping freezing device and a processing method for tilapia fillets. Background technique [0002] After the death of tilapia, the muscles lose water and harden, and the fish meat contains the nutrients needed for the growth and reproduction of microorganisms. Therefore, in the process of killing, processing, dividing, transporting, and selling, the fish meat is easily polluted by microorganisms, resulting in fish meat The color, smell, elasticity, texture, etc. of the fish will change, the fish will spoil and deteriorate, and lose its commodity value, and the storage period of the fish will be short, and the circulation will be limited, which will cause great difficulties to the operators, especially in my country. In the case of an integrated cold chain, the quality of tilapia meat is greatly reduced before it is eaten. This situation directly affects the intere...

Problems solved by technology

[0002] After the death of tilapia, the muscle loses water and hardens, and the fish meat contains the nutrients needed for the growth and reproduction of microorganisms. Therefore, in the process of killing, processing, dividing, transporting, and selling, the fish meat is easily contaminated by microorganisms, resulting in fish meat The color, smell, elasticity, texture, etc. of the fish will change, the fish meat will spoil and lose its commodity value, and the storage period of the fish meat will be short, and the circulation will be limited, which will cause great difficulties to the operators, especially in my country. In the case of an integrated cold chain, the quality of tilapia meat is greatly reduced before it is eaten. This situation directly affects the interests of consumers and operators
