Abstract

The invention discloses a booster pump for food high-pressure sterilization equipment. The booster pump comprises a pump body, a piston and a piston rod, wherein the piston is arranged in the pump body. The booster pump is characterized in that an accommodating groove is formed through inward recessing the lower end surface of the piston along an axial direction; a sub piston block is arranged in the accommodating groove; a mandrel is arranged in the piston rod; the lower end of the mandrel passes into the piston to be fixedly connected with the sub piston block; a center through hole through which the mandrel passes is formed in the piston; a transition groove is formed in the inner side wall of the center through hole; the upper end surface of the sub piston block and the inner surface of the accommodating groove define a sealed air cavity; a first air pipe is arranged in the piston; a second air pipe is arranged in the mandrel. The booster pump used for the food high-pressure sterilization equipment, provided by the invention, has the advantages that food in any form in an accommodating cavity can be subjected to high-pressure sterilization; the sterilization effect is good.

Description

technical field [0001] The invention relates to the technical field of food processing auxiliary equipment, in particular to a booster pump for food high-pressure sterilization equipment. Background technique [0002] High-pressure food processing technology (referred to as HPP) is a relatively advanced sterilization technology in existing food processing. It applies ultra-high pressure to food materials, that is, usually at a pressure of 100-1000 MPa. The covalent bond destroys the high-level structure of the protein, which leads to protein coagulation and enzyme inactivation. In addition, ultra-high pressure can also cause the cell membrane of the bacteria to rupture, causing the chemical components in the bacteria to flow out and other cell damage. The combination of the above factors The effect realizes the technical effect on food sterilization, thus promoting the development of ultra-high pressure sterilization technology in the food industry. In the industry, it is c...
