Special reaction kettle for preparing agricultural probiotic microspheres

Abstract

The invention belongs to the fields of imbedded immobilization of microorganisms and equipments, and in particular relates to a special reaction kettle for preparing agricultural probiotic microspheres. The reaction kettle comprises an upper cover, a kettle body and a bottom, and is characterized in that the upper cover is provided with an annular spray pipe, and a plurality of spray holes are uniformly distributed in the annular side wall of the spray pipe; the kettle body comprises a pair of detachable baffle plates, and a stirring paddle fixed in the center of the upper cover through a shaft sealing structure, and paddle blades are rectangular blades; the bottom is openable or closable, and comprises a microporous filtering plate, a liquid outlet and an air inlet. The microspheres prepared by adopting the reaction kettle provided by the invention have the features of uniform size and regular shape. The reaction kettle provided by the invention is simple in structure, industrialization can be conveniently realized, the synthesis of the microspheres and the separation of the microspheres can be integrated in one reaction kettle, and the synthesis and separation of the microspheresare simultaneously realized; after the reaction is finished, the annular spray pipe is utilized for flushing the kettle body at the first time, so that the cleanliness inside the kettle body is guaranteed. With the reaction kettle provided by the invention, the preparation efficiency of the agricultural probiotic microspheres is greatly improved.

Description

technical field [0001] The invention belongs to the fields of embedding and immobilizing microorganisms and equipment, and in particular relates to a special reaction kettle for the preparation of agricultural probiotic microspheres. Background technique [0002] Microbial fertilizers can partially replace chemical fertilizers to reduce the loss and environmental pollution caused by their large-scale application, but there are many deficiencies in the use of microbial fertilizers. In the soil environment of factors, it is easy to cause the death of a large number of bacteria, and it is difficult to exert the effect of microbial fertilizer. [0003] The microspherization of agricultural probiotics is a kind of immobilization technology. Its essence is to use physical or chemical methods to wrap free microorganisms in specific biological materials. For internal microorganisms, microsphere particles form a microenvironment. The external environment acts as a buffer, which is c...

AI Technical Summary

Problems solved by technology

[0004] According to the data, although there are many devices for microbial immobilization technology, most of them are limited to laboratory research, which cannot meet the requirements of industrial mass production of immobilized agricultural probiotic microspheres.

For example, in the patent document with publication number CN201399340Y, although the preparation of microspheres has been realized, it is not conducive to industrial amplification, and the prepared microspheres can only be obtained after being separated by another equipment.
