Abstract

The invention provides a system and method capable of increasing a protein extraction effect. The system comprises a stirring tank and crushing equipment a, wherein the lower end of the stirring tankcommunicates with a feed opening of the upper end of the crushing equipment a through a pipeline, a valve is arranged on the pipeline, a stirring device is arranged in the stirring tank, and a feed opening is formed in the upper part of the stirring tank; and a discharge opening is formed in the crushing equipment a. According to the system and the method, the particle diameter of protein can be effectively reduced, the protein dissolving and extraction efficiency is improved, the protein extraction time is shortened, the residual amount of protein in bean dregs is reduced, the stability of the protein particles is improved, and besides, the water consumption during protein extraction is reduced.

Description

technical field [0001] The invention relates to a system and method capable of improving protein extraction effect, belonging to the technical field of protein processing. Background technique [0002] Soybean protein is a kind of vegetable protein, which is rich in various essential amino acids and has unique nutritional value. Soybean Protein Isolate is a full-price protein food additive produced from low-temperature desolvated soybean meal. Alkali-dissolution and acid-precipitation process is generally used in the processing of soybean protein isolate. The protein extraction process is mainly based on the principle of alkali-dissolution, and the protein is extracted by controlling a certain pH value, temperature and other conditions. [0003] Soybean protein isolate extraction process usually adopts conventional equipment and process. The process method is: the raw material of soybean meal is mixed with extraction water at about 45 degrees after steam heating for extract...
