Horizontal vacuum paddle dryer for thermosensitive products
Achieve precise drying and mixing of high-viscosity, thermosensitive products with unmatched thermal efficiency, ensuring consistency and purity throughout batch operations. Ideal for processes demanding strict control over moisture levels and material properties.

Drying, Mixing, and Reacting Thermosensitive Materials
The Turbodry MHT-RS from Bachiller is a specialized horizontal vacuum paddle dryer and reactor engineered for handling high-viscosity and thermosensitive materials. This equipment employs a fully heated body and shaft design, coupled with high-speed rotating paddles, to achieve optimal thermal exchange and constant product renewal against the wall, thus ensuring efficient drying and mixing. It’s commonly utilized in industries such as pharmaceuticals, fine chemicals, and food processing for manufacturing active pharmaceutical ingredients, synthetic rubber, and fragrance oils.
The Turbodry operates in batch mode with capacities ranging from 10 to 30,000 liters, supporting vacuum levels down to 1 mbar. Equipped with advanced automation options, it offers robust control with optional hardware/software integration, including pilot plant models for scale-up validation. The design adheres to stringent safety and quality standards, such as ASME VIII div.1, AD-2000, and EN-13445, and is available in ATEX-certified executions for internal zones 0/20. Material finishes include mirror and electro polishing for sanitary conditions, ensuring compliance with cGMP for pharmaceutical applications. For ease of operation, it features a power retention filter, sampling valves, and optional choppers for lump breaking, making it suitable for diverse processing needs.
