AI Technical Summary
During the enzymatic hydrolysis process of oat flour, traditional stirring equipment causes insufficient contact between oat flour particles and enzyme solution, resulting in dead zones and sticky deposits easily forming at the bottom of the reactor. The existing scraper mechanism cannot effectively remove the colloid on the curved surface of the bottom of the reactor.
An oat flour enzymatic hydrolysis equipment with anti-precipitation function is designed. The outer shaft is used to drive the second stirring paddle and stirring blades to form a radial flow. Combined with the spiral blades and screw sleeve structure of the inner shaft, the material is fully mixed and suspended to prevent precipitation.
It effectively enhances the mixing effect of materials, avoids the adhesion and deposition of materials at the bottom of the kettle, and ensures the uniformity and efficiency of the enzymatic hydrolysis process.

Abstract
Description
Technical Field
[0001] The utility model specifically relates to the technical field of oat flour processing, in particular to oat flour enzymatic hydrolysis equipment with an anti-precipitation function. Background Art
[0002] During the enzymatic hydrolysis of oat flour, the material system often exhibits high viscosity and high solids content. This is especially true after the addition of enzymes, as starches tend to form a colloidal suspension. Traditional mixing equipment often utilizes a single axial mixing structure, which has encountered the following technical bottlenecks in actual production: conventional impellers primarily generate axial flow during rotation, resulting in insufficient shear force on the material at the bottom, leading to insufficient contact between the oat flour particles and the enzyme solution; a "dead zone" easily forms at the bottom of the reactor, where unscraped material will undergo localized gelatinization at the enzymatic hydrolysis temperature of 60-70°C, causing adhesive deposits; and existing scraper mechanisms, most of which are fixed or passively rotating, are unable to effectively remove colloidal material adhering to the curved surface of the reactor bottom.
