AI Technical Summary

Technical Problem

Traditional microbial fertilizer production equipment is prone to premature inactivation of functional bacteria during high-temperature stages, the insulation layer cannot cope with extreme temperature differences, the mixture of mesophilic, thermophilic and pyrophilic bacteria leads to nutrient competition, and the discharge port has no screening function, requiring manual screening, which increases process costs.

Method used

The hollow insulation layer incorporates paraffin-based phase change material and is heated by a high-frequency electromagnetic coil to precisely control temperature fluctuations. The multi-layered biodegradable capsules release different functional bacteria in layers, and the discharge hopper integrates a vibrating screen and a spiral blade crushing device to achieve automatic screening.

Benefits of technology

It effectively protects various functional bacteria to function at suitable temperatures, preventing them from becoming inactive. It automatically crushes, screens, and discharges materials without manual intervention, reducing process costs.

Abstract

The utility model relates to the related technical field of fermentation devices, in particular to a fermentation mixer for microbial fertilizer production, which comprises a base, a stand column is fixedly mounted on the upper surface of the base, a discharge hopper is fixedly connected to the upper end of the stand column, and a heat preservation layer is fixedly mounted at the upper end of the discharge hopper. An inner ring of the heat preservation layer is fixedly connected with an inner-layer tank body, a high-frequency electromagnetic coil is arranged on the surface of the inner side of the heat preservation layer, the upper end of the inner-layer tank body is sleeved with a sealing ring, the inner-layer tank body is connected with the sealing cover through the sealing ring, and a paraffin-based phase change material with the melting point being 55 DEG C is arranged in the heat preservation layer. Temperature fluctuation is accurately controlled through melting heat absorption and solidification heat release, compared with a traditional solid structure, thermal resistance is improved, extra heating or cooling equipment is not needed when an extreme temperature difference is coped, a high-frequency electromagnetic coil is matched for direct induction heating of the tank body, and the local overheating problem of resistance heating is avoided; and the problem of inactivation of low-temperature functional bacteria caused by out-of-control temperature in a high-temperature stage is solved.
