Solid material fermentation device

Abstract

The invention discloses a solid material fermentation device. The solid material fermentation device comprises a housing, a flow guide mechanism, and a stirring column; the periphery of the external wall of the housing is sleeved by a thermal insulation sleeve; a thermal insulation chamber is formed between the housing and the thermal insulation sleeve; a plurality of heating sheets are arranged in the thermal insulation sleeve at intervals; the flow guide mechanism comprises a first steel plate, a second steel plate, a first heating plate, and a second heating plate which are arranged in thehousing via clamping; a first flow guide assembly is fixedly arranged on the first steel plate; a second flow guide assembly is fixedly arranged on the second steel plate; a first heating assembly isfixedly arranged on the first heating plate; a second heating assembly is fixedly arranged on the second heating plate; the stirring column is horizontally provided with a plurality of transverse columns; rotating shafts are vertically arranged on the transverse columns downward; the bottom end of each rotating shaft is provided with a rotating disc; the periphery of each rotating disc is providedwith a plurality of stirring blades at equal intervals; the upper edge of each stirring blade is of a curved knife edge structure, and the lower edge of each stirring blade is of a linear knife edgestructure. The solid material fermentation device is capable of realizing full stirring, and achieving excellent stirring effect, and high inoculation rate.

Description

technical field [0001] The present invention relates to the field of fermentation. More specifically, the present invention relates to a solid material fermentation plant. Background technique [0002] Solid-state fermentation refers to a biological reaction process with one or more microorganisms in an underwater soluble solid substrate with a certain humidity in the absence or almost no free water. Considering the essence of the biological reaction process, solid-state fermentation is a biological reaction process in which the gas phase is the continuous phase. The raw materials for solid-state fermentation are generally economical, nutrient-rich industrial and agricultural by-products, waste products, such as bran, Cereals, wheatgrass, common cereals or agricultural products can be used, and the cost of fermentation raw materials is economical. [0003] In the prior art, the fermenter used for solid-state fermentation contains a tank body and a stirring device. The tank...

Problems solved by technology

[0003] In the prior art, the fermenter used for solid-state fermentation contains a tank body and a stirring device. The tank body is mainly used to cultivate and ferment various bacteria, and the stirring device is used to ensure that the materials are mixed evenly to meet the needs of fully mixing with the bacteria. , but in the prior art, the stirring equipment cannot achieve the ideal stirring effect, resulting in the inability to disperse and remove the free water in the solid matrix in time, resulting in insufficient inoculation, and causing the growth of miscellaneous bacteria, affecting the fermentation quality of the material
