Double-Drum Energy-Saving Dryer
High Drying Efficiency: Vacuum-assisted heating accelerates moisture evaporation and speeds up the drying process.
Uniform Drying: Extended material retention time ensures even heat distribution and consistent drying quality.
Energy Saving: The double-drum structure improves heat utilization and reduces energy consumption.
Enhanced Safety: Heat source is isolated from the material, avoiding direct flame contact for safer operation.
Strong Adaptability: Effectively dries materials with both high and low moisture content in a single pass.
Product Introduction
This newly developed practical vacuum dryer by our company adopts a vacuum-assisted principle, overcoming the technical limitations of traditional dryers. The main body features an inner and outer double-drum structure. Under vacuum conditions inside the drum, hot air circulates in the jacket to heat the inner layer, transferring heat to the wet material inside. This process vaporizes moisture in the material, which is then continuously extracted by the negative pressure of the exhaust fan, significantly accelerating the drying rate and ensuring uniform drying. Regardless of the initial moisture content, one-time drying can be achieved.
Dryer Components
The dryer system consists of the following components:
Hot air furnace
Belt conveyor (self-supplied)
Inlet/outlet rotary airlock valves
Main drying drum
Exhaust fan
Cyclone separator
Electrical control cabinet
Performance Advantages
High Safety: The heat source is located below the drying drum and does not come into direct contact with the material. This separation of flame and material improves operational safety.
Excellent Drying Effect: The double-drum structure increases the retention time of the material, ensuring more thorough and even drying, and enhancing overall drying quality.
