Air Flow Dryer

Introduction

The airflow dryer is mainly used in the drying of starch and the drying of some inorganic salt products, such as drying of sodium sulfate and sodium metabisulfite, which has always had its unique advantages. In the feeding mechanism of the air dryer, We have designed a unique anti-arch device, which can ensure the smooth and smooth entry of the raw materials into the air stream dryer without the phenomenon of bridging.

In the main engine of the airflow dryer, a unique pulse link is designed. Some products have relatively high requirements for final moisture. In order to prolong the drying time in the airflow dryer, we have made a pulse expansion section, which will buffer the drying of the product. The speed makes more full contact with the hot air. In the dust removal and collection process of the airflow dryer, considering a large amount of dust, we have made explosion venting devices in the bag filter and the host to achieve the purpose of safe production.

Airflow dryer is a support equipment in pellet mill plant. It is used to dry the raw materials and remove excess water. For making pellets, the water content in raw materials should be kept between 10% and 20%. Drying is a necessary process for materials with high moisture content like grass and green straw.

Working Principle

When you feed powder, granule, and sawdust material into the airflow dryer, they are suspended under the function of air blower. In the drying chamber, they are fully mixed with the hot air and get dried quickly. The dried materials has the water content as low as 10%. 

Features

• Raw materials available: rice husk, saw dust and crushed wood shaving, branches and wood chips. The diameter should be less than 3mm, and the length should be less than 5mm.
• Product efficiency: the temperature of air flow is between 180℃ and 300℃. At the temperature of 180℃, the airflow can lower the moisture content from 30% to 10%.
• Power source: firewood, coal, steam and electricity are all available.
