Fermentation tank for solid material

Abstract

The invention discloses a fermentation tank for materials, and in particular relates to the fermentation tank for solid materials. The fermentation tank comprises a fermentation tank body, a jacket wrapped at the periphery of the tank body, and a stirring device, wherein a feeding port is arranged on a cover at the upper end of the tank body, more than two discharging ports are arranged at the bottom of the tank body, a drive motor is vertically arranged above the tank body and is connected with a stirring shaft through a reduction box, the lower end of the stirring shaft vertically penetrates through the tank body and is installed at the bottom end of the tank body, the stirring shaft is provided with stirring blades, a blank baffle is also arranged at the upper end of the inner wall of the tank body below the feeding port, and zigzag form teeth are arranged on the inner wall at the lower end of the tank body. By adopting the structure, the material is loosened through relative movement of the zigzag teeth and the stirring blades in a stirring process, so that the phenomenon of material extrusion is avoided, therefore, energy consumption for fermentation is lowered and the cost is lowered.

Description

[0001] technical field [0002] The invention relates to a material fermentation device, in particular to a solid material fermentation tank, which belongs to the technical field of biological fermentation devices. Background technique [0003] Solid fermentation refers to a biological reaction process in which a certain amount of oxygen is introduced into a water-insoluble substrate with a certain humidity in the state of no or almost no free-flowing water, and one or more microorganisms are used. In the prior art, solid-state fermentation has a wide application prospect, but at present, most of the solid-state material fermentation adopts a horizontal fermentation device with a rotating shaft. Through the rotation of the spiral stirring blade, the solid-state material is pushed to one end of the fermentation device, and the material is turned during the material transportation process. Insufficient strength and dead angles lead to uneven mixing, uneven nutrients and moistu...
