Vietnam Customer Adopts 0.5-40 Ton Explosion-Resistant Vacuum Drying Machine with Touch Screen Control

A leading food-processing manufacturer in Vietnam was looking for a safer, cleaner, and more efficient way to dry heat-sensitive powder and granule products. After evaluating several suppliers, the company selected our 0.5-40 Ton Vacuum Drying Machine with Touch Screen Control and Explosion Resistance — an industrial vacuum dryer engineered to deliver reliable performance even under demanding production conditions.

Client Background

The client operates in the Vietnamese food and ingredient sector, processing moisture-sensitive materials that cannot tolerate the high temperatures of conventional hot-air drying. They required a system that could dry delicate products at low temperature while meeting strict safety standards for combustible dust. Flexibility was also essential, since their production line handles multiple batch sizes and product types.

The Challenge

• Heat-sensitive raw material that degrades under high drying temperatures
• Safety concerns around combustible dust, requiring explosion-resistant design
• Inconsistent drying quality and long cycle times with their previous equipment
• Need for flexible batch sizes and easy, precise process control

The Solution

We supplied our SZG-series vacuum rotary dryer, a double-conical vacuum drying machine designed for powder and granule materials with good fluidity. The system combines low-temperature drying, uniform heat transfer, and robust explosion-resistance, and is fully customizable from 0.5 ton up to 40 ton capacity.

Key features delivered to the Vietnam client:

• Touch Screen Control: Intuitive operation with options for button, touch screen, or remote control for precise parameter management.
• Explosion Resistance: Special explosion-resistant construction designed to handle combustible dust safely.
• Low-Temperature Drying: Gentle 50-150°C range protects heat-sensitive products while achieving an 80% drying efficiency.
• Flexible Loading Capacity: From 25 KGS per batch to 3000 KGS per batch, matched to the client's varied production needs.
• Multiple Heating Options: Steam, thermal oil, or hot water heating to fit existing plant utilities.

Technical Specifications

Working Principle: SZG Vacuum Rotary Dryer

The SZG Vacuum Rotary Dryer is a double-conical vacuum dryer. Under vacuum conditions, the heat medium is filled into the dryer jacket, and the raw material is dried through contact with the heated dryer chamber. The evaporated moisture is continuously sucked out by a vacuum pump. Because the dryer body rotates, the raw material keeps moving inside the chamber, which increases both drying speed and uniformity. This design is particularly suitable for powder and granule materials with good fluidity.

Results & Benefits

• Achieved a stable 80% drying efficiency with improved batch consistency.
• Low-temperature drying preserved product quality and prevented heat damage.
• Explosion-resistant design met the client's safety and compliance requirements.
• Touch screen control reduced operator error and simplified changeovers.
• Flexible 0.5-40 ton range allowed the client to scale production without replacing equipment.

Conclusion

This Vietnam project demonstrates how a customized, explosion-resistant vacuum drying machine can solve both efficiency and safety challenges in food processing. Whether the requirement is a vacuum drum dryer for small batches or an industrial vacuum dryer for large-scale output, flexible configurations and 80% drying efficiency make the SZG series a dependable choice for exporters and manufacturers worldwide.
