Production equipment and working method of a solid-state fermentation enzyme preparation

Abstract

The invention discloses production equipment of a solid-state fermentation enzyme preparation and a working method of the production equipment. The invention particularly relates to the field of solid-state fermentation enzyme preparation processing. The production equipment comprises a fermentation tank, and supporting legs are fixedly connected to four corners of the bottom of the fermentation tank respectively; and bearing platforms are symmetrically arranged on the two sides of the bottom of the fermentation tank. Bearing plates are symmetrically and fixedly connected to the opposite sidesof the tops of the two bearing platforms. Fixing plates are symmetrically arranged on the other sides of the tops of the two bearing platforms, positioning columns are symmetrically and fixedly connected to the tops and the bottoms of the sides, close to the bearing plates, of the fixing plates, damping springs are fixedly connected to the middles of one sides of the fixing plates, fixing bolts are arranged in the middles of the other sides of the fixing plates, and a supporting table is fixedly connected to the center of the inner wall of the bottom of the fermentation tank. Reaction liquidis heated at the constant temperature through electric heating pieces, the fermentation reaction of the reaction liquid is accelerated, a driving motor drives a rotating shaft to rotate to drive a rotating column to rotate on the supporting table, and a stirring column stirs the reaction liquid, so that the heated liquid is uniformly diffused.

Description

technical field [0001] The invention relates to the technical field of solid-state fermentation enzyme preparation processing, more specifically, the invention relates to a production equipment of solid-state fermentation enzyme preparation and a working method thereof. Background technique [0002] At present, enzyme preparations usually use two production processes: solid-state fermentation and liquid-state fermentation. Among them, solid-state fermentation is a fermentation method of microorganisms on a solid substrate with no or almost no free water. The three phases of gas, liquid and solid coexist in the solid substrate, that is, the porous solid substrate contains water and water-insoluble substances. Compared with liquid fermentation, solid-state fermentation has the following characteristics: there is no flow of free water in the solid-state fermentation medium, which is suitable for the growth of microorganisms with a water activity of 0.93-0.98, which limits the s...

Compared with liquid fermentation, solid-state fermentation has the following characteristics: there is no flow of free water in the solid-state fermentation medium, which is suitable for the growth of microorganisms with a water activity of 0.93-0.98, which limits the scope of application and the growth of some miscellaneous bacteria There is a gradient in the nutrient concentration, the fermentation is uneven, the growth of the bacteria, the absorption of nutrients and the secretion of metabolites are uneven; the contact area between the medium and the gas provided by the solid-state fermentation is large, and the oxygen supply is sufficient. At the same time, The resistance of air passing through the solid layer is small, and the energy consumption is low; using solid raw materials, during the fermentation process, the saccharification and fermentation processes are carried out at the same time, which simplifies the operation process and saves energy consumption; high substrate concentration can produce high product concentration; due to the product The concentration is high, the extraction process is simple and controllable, and there is no large amount of organic waste liquid, but the extract contains substrate components; the degree of mechanization of production is low, and the process control is difficult due to the lack of online sensing instruments
