Name: rotary dryer machine for wood chips sawdust

Introduction

rotary dryer machineis suitable for drying materials from moisture 20%-60% to 6%-8%.

It is consist of hot air stove,inlet, steel buffer cylinders pipe, exhaust fan,air lock

and cyclone separator.

1.It is widely used for drying the powdery,laminar materials like wood sawdust,

crop straw,grain stalks etc.

2.It is specially suitable for drying the starch,albumen powder from food

such as corn,potato etc.

3.It is also for drying the granular and spiny materials in chemical products,

medicine and biomass industry.

Working theory

Wet materials are input into the hopper. It uses the varying diameters of

branch segments of pulse tube and continual change of air flow speed

to constantly thrash the material for drying.The fuel boiler generates

hot air which mixes with wet materials and then is sucked into the

pipes by the exhaust blower (fan) quickly. And then hot air is flowing

and going though the curving pipes and buffer (drying chamber)

of dryer, thus wet materials is finished to dry, and the dried materials

are discharged from the outlet with air lock.

Features

1.As the raw material particles are suspended in the hot air stream,

the heat transfer between the hot air and particle is rapid.

That ensures efficient moisture removal, even with a short transfer time of 3-5 seconds

2.Once the moisture hot air and particles reach the cyclone separator,

the particles leave the through the base and moist hot air leaves through

the top of the cyclone.The buffer cylinders are to increase particle resonance

time in the hot air stream.

3.The dryer usually uses coal, firewood and gas as heating source.

Combustible gas as the heating resource can save labor 75%.

4.it not only reduces the labor intensity but also can reuse the fuel gas
