China Factory Suppliers DW Series Multiple Layers Mesh-Belt Dryer for Efficient Drying Solutions
Principle
Air flow is counter current: high temperature and low moist air is blowing from bottom layer to upper layer and contact with wet material. When hot air contacts with material, it will absorb moisture inside and remove the moisture out of the drying chamber by the exhaust fan.
It is a fully automatic and continuous operating drying machine, in which raw material will turn over during falling down to the next conveying belt that will ensure a uniformly drying result.
Low labor consumption and good working condition. This type of mesh belt dryer is also easy for maintenance.

Frequently Asked Questions
How does the counter-current airflow principle work in this dryer?
The dryer utilizes a counter-current system where high-temperature, low-moisture air is blown upward from the bottom layers to the top. As this hot air contacts the wet material moving down, it absorbs the internal moisture and exhausts it out of the chamber using an integrated exhaust fan.
What is the operating temperature range of the DW3 series mesh belt dryer?
The DW3 series mesh belt dryer operates within a temperature range of 50°C to 150°C, making it highly adaptable for various material drying requirements.
What material thickness can the conveying belt accommodate?
The equipment is designed to process material layer thicknesses ranging from 10 mm up to 80 mm for optimal drying efficiency.
What steam pressure is required for the heating system?
The dryer requires a stable steam pressure of 0.2 to 0.8 MPa to maintain consistent and efficient heat exchange performance.
How does the machine ensure uniform drying of the raw materials?
Uniform drying is achieved because the raw materials automatically turn over as they fall from one conveying belt level down to the next level during continuous operation.
