Method and equipment for preparing straw protein through secondary fermentation of rhizopus oligosporus

Abstract

The invention belongs to the technical field of fertilizer production, and particularly relates to equipment for a preparation method of rhizopus oligosporus secondary fermentation straw protein.The equipment comprises a fermentation tank, the outer surface of the fermentation tank is fixedly connected with a supporting frame, the fermentation tank is of a conical structure, the lower surface of the fermentation tank is fixedly communicated with a discharging pipe, and the upper surface of the fermentation tank is connected with a sealing cover in a covering mode; a stirring device is arranged in the fermentation tank and comprises an arc-shaped stirring pipe, the outer surface of the arc-shaped stirring pipe is attached to the inner wall of the fermentation tank, and materials in the fermentation tank are uniformly stirred. According to the preparation method and equipment of the rhizopus oligosporus secondary fermentation straw protein, the auger stirring rod rotates along with rotation of the main stirring pipe, the auger stirring rod can drive materials in the discharging pipe to stir up and down, so that the materials are uniformly stirred, and when the cover body is taken down, the auger stirring rod rotates to stir the materials in the discharging pipe up and down, so that the materials are uniformly stirred. And the fermented materials can be conveyed out from the discharge pipe, so that the fermentation efficiency of the materials in the fermentation tank is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to equipment for a method for preparing straw protein from secondary fermentation of Rhizopus oligosporus. Background technique [0002] In recent years, bio-organic fertilizer has attracted widespread attention as a bio-fertilizer that combines the advantages of organic fertilizers and functional strains. It has shown good effects in disease prevention and control, crop growth promotion, and soil improvement. Therefore, bio-organic fertilizers can be introduced into the "farmland planting ginseng" planting system to improve soil effectiveness and maintain soil fertility. [0003] Studies have shown that suitable fermentation conditions are of great significance to improve the quality of bio-organic fertilizers. Fermentation time, inoculum size, fermentation temperature, and water content are all key factors for solid-state fermentation of bio-organic fertilizers. Stu...

Problems solved by technology

Studies have found that after the content of available selenium in the soil is increased, the available selenium content of the fruits grown by plants is increased by 10-25%. At the same time, our 3-year experiment on the soil shows that the improved soil after the second fermentation has no effect on the fruits grown by plants. The molecular structure of starch becomes smaller, and the speed of conversion of starch and salivary enzymes into maltose increases the sweetness and taste of food. However, the existing straw fermentation pile makes the soil active selenium content is not high, and the bean dregs and When the fungicides are mixed and fermented, due to the uneven mixing between the two and the difficulty in controlling the humidity of the bean dregs, the fermentation effect between the two is poor, so the active selenium content of the soil cannot be increased, so the proposal of the present invention solves the above technical problems. insufficient
