Abstract

The invention discloses a soybean meal enzymolysis feed additive production system and production method, and relates to the field of feed additives. The soybean meal enzymolysis feed additive production system at least comprises a soybean meal enzymolysis reaction kettle for performing enzymolysis on soybean meal, wherein the soybean meal enzymolysis reaction kettle comprises a reaction kettle shell and an ultrasonic generator installed on the outer wall of the reaction kettle shell. The soybean meal enzymolysis feed additive production system has the beneficial effects that the ultrasonic generator is arranged on the outer wall of the shell of the reaction kettle, protease and soybean meal solids are crushed into fine particles under the action of ultrasonic waves, a good condition is provided for contact between the protease and the soybean meal, the agglomeration phenomenon of solid particles is reduced, and dispersion and floating of gas in liquid are quickened; and mass and heat transfer and enzymolysis effects are improved, water consumption in a production process is greatly reduced, and the stability of product quality is ensured.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a soybean meal enzymatic hydrolysis feed additive production system and a production method thereof. Background technique [0002] Protease is an important class of enzymes in feed enzyme preparations. It is an enzyme that catalyzes protein hydrolysis. It has the characteristics of high efficiency and catalytic substrate specificity, and is most widely used in the feed industry. There are three main sources of protease, animal origin, plant origin and microbial origin. Among them, microbial-derived proteases are stable, safe and efficient, and the production cost is relatively low. Therefore, microbial-derived proteases are mainly used in the feed industry . [0003] According to the different pH of enzyme action, protease can also be divided into acid protease, neutral protease and alkaline protease, and acid and neutral protease are mostly used in the feed industry. The protein ...
