The vacuum drying technology is one of the most economical and most gentle drying methods. Due to the vacuum very low water evaporation temperatures can be reached. Aroma, product color and bulk density can specifically be influenced by the process. Vacuum Belt Dryers are used in the Pharmaceutical Industry, Food Industry and Chemical Industry.

Vacuum Belt Dryers are designed for the continuous operation with liquid or solid products. The dried granulate is also quasi-continuously discharged and can be removed under cleanroom conditions (GMP). After the drying process, the product can be ground, filled and packaged.

VACUUM DRYING CHARACTERISTICS

Individual temperature zones
The modular design of the heating plates allows use of product-specific temperature profiles for a tailor-made drying process.

Visual monitoring 

The current drying process can be monitored continuously via sight glasses. Optionally, automated monitoring systems are available.

Maintainability

The walk-in design ensures ease of access for maintenance and servicing of the dryer equipment.
