Horizontal vacuum paddle dryer for thermosensitive products
For high-viscosity products like active pharmaceuticals or polymers, achieving consistent drying and mixing is crucial. This vacuum paddle dryer ensures optimal moisture removal and uniform product quality, perfect for thermosensitive materials requiring gentle yet effective processing at precise temperature controls.

Dries and Mixes High-Viscosity Products Efficiently
The PADDLEDRY (MHT-S) Horizontal Vacuum Paddle Dryer from Bachiller is designed for batch processing high-viscosity and thermosensitive materials across industries such as pharmaceuticals, chemicals, and food additives. Utilizing a continuous heat exchange system facilitated by a heated shaft and blades, it ensures effective drying and mixing. Ideal for products with pseudo-plastic behavior, the equipment can operate at vacuum levels down to 1 mbar and handle temperatures up to 350º C, making it suitable for sensitive compounds like APIs, cosmetics, and pigments. With capacities ranging from 50 to 30,000 liters, PADDLEDRY ensures short drying cycles and maximum thermal efficiency.
It supports seamless integration within production lines, being fully programmable and featuring varying speed controls to match diverse process requirements. Constructed in compliance with ASME VIII, AD-2000, and EN-13445 standards, it’s available with customizable features such as mirror-polished interiors and ATEX certification for explosive environments. A variety of discharge and sampling valves, dust filters, and choppers for breaking down product lumps are options, enhancing its versatility. Additionally, Bachiller offers extensive engineering support and customization to meet specific production needs, making PADDLEDRY a robust choice for optimizing your drying operations.
