Avemectin Fermentation Bacterial Residue Rotary Flash Dryer XSG1600

The spin flash dryer is primarily used to dry the fermentation bacterial residue of avermectin. This material is a filter cake with certain viscosity and occasional clumps. The process flow is as follows: Ambient air, filtered through primary and medium-efficiency filters, is blown by the drying system's blower into an air heater composed of a steam radiator and an electric heater, where it is heated to the process-set temperature. The heated air then enters the main spin flash dryer, where it undergoes a heat and mass transfer drying process with the filter cake to be dried, which is fed into the main dryer via a screw feeder. The gas-solid mixture is separated by a cyclone separator and a bag filter. The material is separated from the drying system's gas and discharged from the system, while the exhaust gas is released into the atmosphere by an induced draft fan, thereby quickly obtaining the finished product.

Using avermectin residue as raw material, after microbial fermentation treatment, separation, concentration, and drying processes, a product is prepared as a nutrient component for avermectin fermentation culture medium. This product is then applied in the avermectin fermentation medium. It addresses the environmental pollution issue caused by avermectin fermentation waste residue, achieves the recycling and reuse of the waste residue, and attains the goal of clean production.
