PSTM Engineering Pvt. Ltd.

Agitated Thin Film Dryer (ATFD) is used across industries to gently and efficiently dry heat-sensitive materials like pharmaceuticals, chemicals, food ingredients, and biotechnological products while preserving their quality and integrity. It's great for substances that can't withstand high temperatures and need gentle processing.

We engineer the equipment to handle a wide range of materials, ensuring uniform drying, minimal degradation, and high throughput.

Advantages of PSTM Agitated Thin Film Dryer: -

• Suitable for Highly Viscous Fluid
• Low residence time
• Low pressure drop allowing operation down to 1 mbar absolute
• Robust design minimizing maintenance costs
• No dead zones and no liquid hold-up
• Easy to clean
