High-Efficiency Vacuum Belt Dryer for Heat-Sensitive Solid Materials
The ZDG vacuum belt dryer (solid) is a high-performance continuous vacuum drying equipment designed for low-temperature, gentle drying of heat-sensitive solid materials.
This advanced industrial vacuum dryer is widely used in pharmaceutical, food, chemical, and biotechnology industries, ensuring high-quality drying while preserving material color, flavor, and active ingredients.
It is especially suitable for products requiring strict moisture control and high purity standards.
Why Choose ZDG Vacuum Belt Dryer?
Our vacuum belt drying system is engineered for efficiency, stability, and product quality:
- Continuous feeding and discharging under high vacuum
- Low-temperature drying to protect heat-sensitive materials
- Multi-layer belt design for higher capacity
- Independent temperature control for each drying zone
- Energy-efficient operation compared to traditional dryers
- Fully automated control system for stable production
Working Principle of Vacuum Belt Dryer
The vacuum belt dryer (solid) operates by evenly distributing material onto a moving conveyor belt through a specialized feeding system.
Under a controlled vacuum environment:
- Material is transported continuously at uniform speed
- Heating plates below the belt provide precise thermal energy
- Moisture is gently evaporated at low temperature
- Material passes through multiple drying layers
- Final product is cooled, loosened, and discharged automatically
The system ensures efficient heat transfer, minimal thermal degradation, and consistent product quality.
