Solid-state fermentation machine

Abstract

The invention relates to a solid-state fermentation machine. The solid-state fermentation machine comprises a cylinder fermentation box with the closed upper end. A central discharging mechanism is installed at the center of a circular fermentation bed on the lower portion of the cylinder fermentation box; the upper end of the central discharging mechanism extends to the middle in the height direction of the cylinder fermentation box; the cylinder fermentation box is provided with a central feeding pipe; the lower end of the central feeding pipe is connected with a rotatable feeding inclined sliding pipe; an annular guide rail is fixedly installed on the inner wall of the middle in the height direction of the cylinder fermentation box; a main beam horizontally extending in the radial direction is installed on the top of the central discharging mechanism; the outer end head of the main beam is supported on the top face of the annular guide rail and can rotate around the axis of the central discharging mechanism; a horizontal conveying spiral conveyor is installed on the rear side of the main beam; a spiral conveyor blocking plate extending in the full-length direction of the spiralconveyor is arranged on the rear side of the horizontal conveying spiral conveyor; the inner end head of the horizontal conveying spiral conveyor is connected with a discharging door of the central discharging mechanism in a butting mode; and the lower end of the feeding inclined sliding pipe is connected with the inner end head of the horizontal conveying spiral conveyor in a butting mode. The slid-state fermentation machine is high in production efficiency and good in product quality.

Description

technical field [0001] The invention relates to a disc fermentation equipment, in particular to a solid-state fermentation machine, which can be used for the fermentation of meal materials and belongs to the technical field of fermentation machinery. Background technique [0002] Solid-state fermentation of meal by biotechnology is currently a fast-growing deep-processing technology for meal. Under human-controllable conditions, some macromolecular substances such as polysaccharides, proteins, and fats are degraded through microbial metabolism, and organic acids, soluble Peptides and other small molecular substances form a biological feed or feed material that is rich in nutrition, good in palatability, and high in live bacteria. [0003] Fermentation equipment essentially needs to be compatible with the fermentation process. At present, domestic meal solid-state fermentation equipment mainly includes: belt type, floor (stack type fermentation), cement pool / trough (pool typ...

AI Technical Summary

Problems solved by technology

[0006] Tank fermentation is suitable for anaerobic submerged fermentation of higher material layers. Large-scale tank-type airtight containers can provide an anaerobic environment. The fermented material has a high content of small peptides and high viscosity. It is difficult to use mechanical automation equipment to discharge the material. Only Using manual handling, the production environment is harsh and labor-intensive, which is not conducive to the stability of the fermentation environment
