Advantages
Belt dryers in the EBT series are characterized by
- No mechanical stress on the product
- Temperature ranges from 20 to 250°C
- Temperature profile possible in the dryer
- Drying with air or in superheated steam
- Low maintenance
- Combination of drying and cooling in one appliance
- Infinitely variable belt speed
- Adjustable drying time
- High energy efficiency
- Internal and external heat recovery
- Low-dust exhaust air
- Good cleanability due to good accessibility
- Simple operability
- Dryer can be expanded thanks to modular design
Procedure
In a continuous convection belt dryer, hot air flows through an aerated product layer on a perforated belt. The air flow removes the evaporating water. Part of the water-laden air is extracted as exhaust air and replaced by fresh air (recirculated air). In this way, water is continuously removed from the dryer.
The process parameters are highly product-dependent and can be clarified by us.
Execution
In a continuous convection belt dryer, an aerated product layer is transported on a perforated belt through a drying chamber and dried with warm air.
