AI Technical Summary

Technical Problem

In existing technologies, ordinary mixing equipment is difficult to fully mix the cohesive soybean meal raw materials, which prevents the liquid microbial agent from penetrating into the interior of the clumps, resulting in uneven material mixing and affecting fermentation efficiency and product quality consistency.

Method used

A soybean meal mixing and fermentation device was designed, which includes a mixing component and a spraying and dispersing component. By using the mixing rod and nozzle in combination, the soybean meal clumps are automatically sprayed with gas to achieve full dispersing and dispersion, ensuring the synchronous mixing of liquid inoculant and dry material, and maintaining an anaerobic environment.

Benefits of technology

It achieves thorough mixing of soybean meal raw materials, ensures uniform contact between liquid inoculant and dry materials, improves fermentation efficiency and product quality consistency, and is particularly suitable for the fermentation of soybean meal that is prone to clumping.

Abstract

The application discloses a soybean meal stirring fermentation device, which comprises a fermentation cylinder assembly, a stirring assembly and a jetting and dispersing assembly. The jetting and dispersing assembly comprises a support plate frame, a rotating connecting rod, a third bevel gear fixed to the end of the connecting rod and a rotating disc. In order to solve the problem that the common soybean meal fermentation equipment is difficult to fully disperse the viscous lumps of soybean meal with a moisture content of 55-60% during the fermentation stirring, the application designs the stirring assembly and the jetting and dispersing assembly, which are matched and arranged, so that the soybean meal lumps can be automatically jetted by gas during the stirring, the lumps can be fully broken up and dispersed through the stirring and jetting, the liquid fungicide and the dry material can be fully mixed synchronously, no external gas is introduced, the anaerobic environment is ensured, and the device is particularly suitable for the fermentation of the soybean meal which is easy to form lumps.
