A preparation device for microorganism immobilized particles

Abstract

The invention discloses a preparation device for microbial immobilization particles, comprising a support plate, a single chip microcomputer is arranged on the left side of the upper surface of the support plate, a cylindrical hollow shell is arranged directly above the support plate, and an outer surface of the cylindrical hollow shell is arranged There is an exhaust hole on the right side of the upper end of the side surface, the middle part of the outer side of the cylindrical hollow shell is connected with the upper surface of the support plate through the support frame, and the inner side of the cylindrical hollow shell is provided with a second electric heating sheet, the cylindrical hollow shell is The hollow shell is rotatably connected with a screw through a bearing arranged on the inner side thereof. The microorganism immobilized particle preparation device has a compact structure, high output and low cost, and can easily mass-produce the microorganism solid particles. The blade can cut the solid gel containing microorganisms, the setting of the air pump combined with the hot air pipe can quickly solidify the microbial gel particles, and the setting of the stirring screw enables the microorganisms to be evenly distributed on the outer side of the gel.

Description

Technical field [0001] The present invention relates to the art of preparing microbial curing particles, and is specifically a microbial immobilized particle preparation device. Background technique [0002] Microbial immobilization techniques are bioabolic to bind microbiology using biological or chemical multimeric materials, and the free microorganism is positioned in a defined space area, which not only greatly enhances the microbial concentration of the reaction, so that the microorganism is not easily lost and anti-poison. The increase of tolerance, can be repeated and continuous, and the solid-liquid separation is easy, and the secondary pollution is small, especially in environmental governance and metabolites have a good application prospect. Among the immobilized particles of the microorganism, small molecular substrates and metabolites can be free to access the apertures of these immobilized carriers, while microbial cells cannot move freely. At present, the microbial ...

Problems solved by technology

The method of dividing after forming in the forming frame refers to making the carrier block in the forming frame, injecting the crosslinking agent into the forming frame, taking out the carrier block after forming and cutting it into small cube particles; The internal cross-linking time is inconsistent, the internal viscosity is high during cutting, and the pore size difference of small particles after cutting is too large, which makes it difficult for microorganisms to exchange substances with the outside world or easy for microorganisms to escape

The drop granulation method is to drop the mixture of microorganisms and polymer materials into the cross-linking liquid to produce a spherical carrier. This method not only wastes raw materials, but also forms a spherical shape when the dropping speed is too slow. If the dropping speed is too fast, it will form Strips, and there are small dripping particles that are easy to stick together and have problems such as uneven particle size
