AI Technical Summary

Technical Problem

The prior art cannot effectively ensure the drying effect in the spray drying treatment of traditional Chinese medicine extracts, which affects the subsequent processing effect of traditional Chinese medicine drugs or Chinese herbal medicines.

Method used

A material dehumidification and drying system is designed, including a primary drying tower and a secondary drying conveyor. A spiral hot air passage and a high-speed atomizer are provided in the drying tower, and the secondary drying conveyor is subjected to enhanced dehumidification and drying through an electric heater and a spiral stirrer.

Benefits of technology

Through the addition of the secondary drying conveyor, enhanced drying and dehumidification treatment is carried out in the primary drying tower, avoiding the problem of insufficient drying and hot air-heat energy, improving the drying effect, and ensuring the quality of subsequent traditional Chinese medicine processing.

Abstract

The utility model discloses a material dehumidifying and drying system which comprises a primary drying tower, the top of the primary drying tower is communicated with a spiral hot air channel, and drying hot air is introduced into the hot air channel; a high-speed atomizer is further arranged at the top of the inner cavity of the tower body of the primary drying tower, and materials are fed into the high-speed atomizer through a feeding opening; two branches are formed at a discharge hole in the bottom of the primary drying tower, one branch is connected with a cyclone separator, the other branch is connected with a secondary drying conveyor, the secondary drying conveyor is connected with the cyclone separator through a discharge hole in one side of the bottom, and a dried material discharger is arranged at the bottom end of the cyclone separator. Due to the fact that the secondary drying conveyor is additionally arranged, after drying treatment is carried out in the primary drying tower, enhanced drying and dehumidification treatment can be achieved selectively through the secondary drying conveyor. And the problem that the subsequent processing effect of traditional Chinese medicines or traditional Chinese medicine decoction pieces is affected due to poor drying effect without materials can be avoided.
