Description

TECHNICAL FIELD

[0001] The application relates to the technical field of food processing, and in particular to a high-temperature sterilization device for vacuum-preserved sweet waxy corn production. BACKGROUND

[0002] The high-temperature sterilization device for vacuum-preserved sweet waxy corn production is a device specially used in the processing of sweet waxy corn, which kills microorganisms on the surface and inside the corn through high-temperature means to achieve the purpose of subsequent vacuum preservation. The principle is generally to use the lethal effect of high temperature on microorganisms, and to use saturated steam, superheated steam or high-temperature hot water as a heat medium. The sweet waxy corn is placed in a high-temperature environment for a certain period of time. Under high temperature, the biological macromolecules such as proteins and nucleic acids in the cells of microorganisms denature and coagulate, enzymes lose activity, and the physiological functions and metabolic activities of cells are destroyed, thereby achieving the purpose of sterilization.
