Pneumatic Pipe Dryer: Working Principle and Features

Pneumatic pipe dryer, also known as airflow dryer or flash dryer in the industry, is widely used for material dewatering in industrial production. It is specially designed for drying fine materials with excellent practical performance.

Wet materials are fed into the drying pipeline.

Internal lifting plates keep turning and scattering the materials.

Materials mix fully with high-temperature hot airflow and move forward together.

Materials are evenly dispersed to make full contact with hot air.

Heat transfer and dewatering proceed rapidly to remove internal moisture.

A matched separator separates dried materials from water vapor.

Waste hot air and steam are discharged from the top of the cyclone.

The whole process runs continuously and automatically.

This dryer has clear requirements on material size.

It is suitable for fine and light materials such as sawdust, rice husk, bamboo dust, wood shavings and wood chips.

Normal drying is available when material diameter is within 3 mm and length within 5 mm.

It fits most drying scenarios of fine biomass materials.

The drying cycle is extremely short.

Materials stay in high-temperature airflow only for a short time.

For heat-sensitive and low-melting materials, overheating, decomposition and deterioration can be avoided.

The original quality and uniform appearance of finished products are well maintained.

The equipment is compatible with multiple heating methods.

Available heat sources include wood, coal, biomass pellets, gas burners and steam heat exchangers.

It adapts to production sites and budgets of different customers with high flexibility.

Rapid airflow heat exchange and fully dispersed materials accelerate heat and mass transfer.

It takes much less time than conventional drying equipment.

The high efficiency well meets the demand of continuous mass production.

The machine is simple to operate and runs stably without complicated commissioning.

Pipelines can be installed in folded layout for flexible arrangement.

It occupies little floor space and is easy to install, relocate and maintain.

It is an ideal choice for small and medium-sized workshops.
