Multilayer type solid material fermenting device

Abstract

The invention discloses a multilayer type solid material fermenting device. The multilayer type solid material fermenting device comprises an outer cylinder, an inner cylinder, a stirring column and aplurality of material disks, wherein a plurality of air-permeable ports are formed in the side wall of the inner cylinder; one side, positioned on the inner side wall of the inner cylinder, of each air-permeable port is covered with a blocking mechanism; the side wall of each material disk comprises a first steel plate and a second steel plate; the end parts of the first steel plate and the second steel plate are in butt joint to form a ring-shaped cylinder body; the bottom surface of each material disk comprises a fan-like second bottom plate as well as a ring-shaped first bottom plate witha notch matched with the second bottom plate; the stirring column is positioned above each material disk and fixedly connected with a strip-shaped scraping plate; one end, near the stirring column, ofthe second bottom plate is fixedly connected with a steel wire; the other end of the steel wire passes through a second ferrule and is fixedly connected with a first ferrule; and the second bottom plate is in an open state when the steel wire moves downwards, and the second bottom plate is in a closing state when the steel wire moves upwards. The multilayer type solid material fermenting device has the beneficial effects of simplicity in operation, mixing uniformity, 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.

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
