Multi-layer solid material fermentation device

Abstract

The invention discloses a multi-layer solid material fermentation device, comprising: an outer cylinder; an inner cylinder, the side wall of the inner cylinder is provided with a plurality of air vents, and each air vent is located on one side of the inner wall of the inner cylinder The uniform cover is equipped with a blocking mechanism; a stirring column; a plurality of material trays, the side walls of the material trays include a first steel plate and a second steel plate whose ends are butted to form an annular cylinder, and the bottom surface of the material tray includes a fan-like The second bottom plate, and the annular first bottom plate with a notch suitable for the second bottom plate; wherein, the stirring column is fixedly connected with a strip scraper above each material tray; the second bottom plate is close to One end of the stirring column is fixedly connected with a steel wire, and the other end of the steel wire passes through the second ferrule and is fixed on the first ferrule, the steel wire moves down, the second bottom plate is in an open state, and the steel wire Move up, the second bottom plate is in the closed state. The invention has the beneficial effects of simple operation, uniform mixing, good drying effect and high inoculation rate.

Description

technical field [0001] The invention relates to the technical field of fermentation. More specifically, the present invention relates to a multi-layer solid material fermentation device. 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 d...

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
