Wood Pipe Dryer Introduction

Sawdust pipe dryer, also known as flash pipe dryer, has broad application in drying various biomass materials (diameter≤ 3 mm, length≤ 5 mm) like rice husk,wood sawdust and crushed branches, pieces, etc. by direct heating. It covers little space since the installation can be pulled down, thus it enjoys wide popularity for relatively smaller industrial workshop. The humid wood sawdust and high temperature air flow concurrently and then moisture is separated from sawdust. Flash dryer is applied in a myriad of industrial fields such as wood pellet, food, feed, chemistry, drugs and mining, etc.

Sawdust Flash Dryer Features

1.High drying strength. Thanks to the high airing speed, wood sawdust spreads evenly and has large drying area;thus has high heat transferring strength.

2.Short drying time. The contacting time of wood sawdust and air is quite short and drying time lasts 0.5-5 seconds. For those heat sensitive or low melting point materials, pipe dryer will never destroy them and affect their quality.

3.High heating efficiency. Biomass materials and air are flowing concurrently, thus the temperature of materials and air can reach a reasonable state; drying moisture content of sawdust or rice husk from 35% to 10% when the air is 180℃(always above 180℃).

4.Wide application, high drying efficiency; simple structure and space saving; little investment and maintenance cost.

5.Optional hot air sources: oil stove, gas stove, coal stove or vapor heat exchange.
