Airflow Dryer

Product introduction

Dry raw materials: granular raw materials such as rice husks, sawdust and crushed flowers, branches, wood chips (diameter less than 3mm, length less than 5mm).
Production efficiency: When the hot air is 180°C, sawdust or rice husk with a relative humidity of 35% is dried to a relative temperature of 10%.
Fuel options: wood (broken firewood), coal, steam or electric heating.
This wood dryer reduces the moisture to 8-12%.

1. Granular wet materials are added from the feeding port, and the hot gas passes through the porous gas distribution plate at the bottom of the fluidized bed, forming many small airflows that are injected into the material layer.
2. When the operating air speed is controlled within a certain range, the granular materials are suspended in the rising air flow to form a boiling fluidized bed. The granular materials in the material layer collide with each other and mix violently, resulting in a heat and mass transfer process between the gas and solid phases. It is strengthened so that the material can be dried.
3. The dried product is discharged through the bed side discharge pipe, the wet waste gas is extracted from the top of the bed by an induced draft fan, and a small amount of entrained fine powder is separated by a cyclone separator.
