Cyclonic flash drying device

Abstract

A cyclonic flash drying device comprises an air filter, an air dehumidifier, an air blower, an air heater, a screw feeder, a drying main machine, an impact type cyclone drying tower, a cyclone separator, a dust catcher and an induced draft fan. High temperature low-humidity air output by the air blower is divided into two ways, one way leads to the air heater, the other way leads to a Dukang cone arranged on the upper portion of a discharge outlet of the cyclone separator, hot air output by the air heater is divided into two ways, one way leads to an air inlet of the drying main machine, the other way leads to an air inlet of the impact type cyclone drying tower, a dynamic flow stabilizing ring is arranged on the portion of the inside of a cylindrical body of the drying main machine, a lifting type stirrer is disposed on the lower portion of the inside of the cylindrical body of the drying main machine, upper and lower layers of impact type cyclone rings are fixed on the inner wall of the impact type cyclone drying tower, the screw feeder extends into the drying main machine, and a discharge outlet is located above the lifting type stirrer. The collection efficiency of finished products can be improved through the drying device, and the drying device is suitable for production drying technologies for products containing high sugar and grease.

Description

technical field [0001] The present invention relates to cyclone flash drying equipment. Background technique [0002] The drying medium of flash drying generally adopts ambient air. After the ambient air passes through the air filter, it is blown into the steam heat exchanger, coal or fuel oil or gas hot air stove by the fan to be heated, and the heated hot air passes through the hot air of the flash evaporation host The distributor is distributed into a cyclone with uniform flow rate and flow direction. The cyclone contacts and collides with the wet material added by the screw feeder, and a series of physical changes such as mass heat exchange and separation begin, so that the material is separated from the moisture contained in it, and finally dried. Chinese Patent No. 92242824.7 utility model patent specification discloses a cyclone flash dryer, including a drying chamber and a cyclone separator, the heater is connected to the distributor, and a feeder is provided on the...

AI Technical Summary

Problems solved by technology

In the production and drying process of products containing sugar and oil in the pharmaceutical, biochemical, food and other industries, due to the characteristics of low heat-resistant temperature of the material and slow moisture migration during the drying process, drying in an ordinary cyclone flash dryer The above materials often have disadvantages such as materials are not easy to dry, products are easy to soften or coke, and the collection rate of finished products is low
