Vacuum Belt Industrial Spray Dryer is a continuous infeed and discharge vacuum drying system designed for efficient processing of liquid and paste materials. The equipment operates under high vacuum conditions, lowering the boiling point of liquids to enable low-temperature evaporation while preserving product quality.

Liquid product is conveyed into the dryer body by an infeed pump and evenly distributed onto moving belts. Under high vacuum, water in the liquid material evaporates at reduced temperatures. The belts move across heating plates using steam, hot water, or hot oil as heating media. The product progresses through evaporation, drying, cooling, and final discharge stages.

• Reduced labor costs and energy consumption
• Minimal product loss with solvent recycling capability
• PLC automatic control system with CIP cleaning
• Excellent product solubility and quality output
• Continuous vacuum processing from feed to discharge
• Fully enclosed system prevents contamination
• Adjustable drying temperature (30-150°C) and time (30-60 minutes)
• GMP standards compliance

Note: Evaporation capacity increases with organic solvents (ethanol, methanol, etc.) and is closely related to drying temperature.

Ideal for drying various liquid and paste materials including traditional and western medicines, food products, biological materials, chemical substances, health foods, and food additives. Particularly suitable for high-viscosity materials, products prone to agglomeration, thermoplastic substances, heat-sensitive materials, and materials incompatible with traditional drying methods.
