Straw Rotary Dryer

Introduction

Straw Rotary Dryer is a robust, industrial-scale thermal processing system specifically designed to efficiently and continuously reduce the moisture content of various agricultural residues, primarily straw (e.g., rice straw, wheat straw, corn stover) and similar biomass materials.

Working Principle

During the drying process of the straw dryer, the straw is first added to the silo by the forklift, and then the straw are evenly sent to the dryer by the belt conveyor for drying.
The straw enter the drum from the feeding device and are pushed backward by the spiral flight board. Due to the inclined placement of the dryer, on the one hand, the material flows to the rear end under the action of gravity and rotation; on the other hand, the material is repeatedly picked up by the lifting board, brought to the upper end and then continuously sprinkled down, so that the material forms a uniform curtain in the cylinder, to fully exchange heat with the hot air in the cylinder. With the material repeatedly scattered, the moisture contained in it is gradually dried, so as to achieve the purpose of drying.
The dried material flow into the elevator from the discharge hopper, and enter the transfer bin through the elevator. The material enters the granulator machine through the transfer bin, and is pressed into biomass particles, and then packed into bags after being cooled by the cooler. , sent to the designated place for storage.
The upper part of the unloading hopper is the dust during the unloading process. After being treated by the dust removal system, it can achieve the purpose of environmental protection.
