Rapid preparation method of fluid inoculum for solid-state fermentation, application method and device

Abstract

The invention relates to a rapid preparation method of fluid inoculum for solid-state fermentation production of industrial microorganism, an application method and a device thereof. The method comprises a feeding step, a stirring step and a pumping step, wherein in the feeding step, a fermented solid-state material (solid-state inoculum) and solution are conveyed into a device with a stirrer; in the stirring step, the mixed materials in the device are stirred till the mixing materials become fluid inoculum which has certain flowability and can be pumped; and in the pumping step, the fluid inoculum is pumped and conveyed outside.

Description

technical field [0001] The invention relates to a method and special equipment for rapid preparation and application of microbial solid-state fermentation fluid inoculum for industrial production. The invention belongs to the preparation and application technology of solid-state fermentation inoculum. technical background [0002] In order to rapidly ferment solid materials, a method of uniformly mixing a certain proportion of fermented solid materials as inoculum with new solid materials is generally adopted. This method is labor-intensive and time-consuming in the case of large-scale industrial production, and the effect is not good. Such as dry anaerobic fermentation, generally a certain amount of anaerobic fermentation materials and raw materials are pre-mixed evenly, and then put into the fermentation device, or the two are stacked in layers in the fermentation device, and then stirred evenly. The above-mentioned former solution needs to be equipped with a pre-mixer w...

AI Technical Summary

Problems solved by technology

The above-mentioned former solution needs to be equipped with a pre-mixer with a large production capacity, and the above-mentioned latter solution must preset an empty fermentation device, which will inevitably reduce the utilization rate of the fermentation device, thereby reducing the system efficiency

In addition, in actual production, the pretreatment of raw materials often needs to be carried out in the fermentation device, so the fermentation device has been filled with raw materials before inoculation. Due to the large area of ​​industrial-scale fermentation devices, if you want to add solid inoculum to the surface of raw materials at this time There are greater difficulties in operation, and in the subsequent mixing steps, it is difficult to mix these solid inoculum and raw materials evenly
