Vertical conical screw vacuum dryer
Achieve precise moisture control with ultra-vacuum batch drying, ideal for thermo-sensitive products. The conical screw design ensures efficient mixing and drying, perfectly integrating into processes requiring exact particle consistency and enhanced purity levels.

Dries and Mixes Thermo-Sensitive Materials Efficiently
The Vertical Conical Screw Vacuum Dryer (MCV-S) from Bachiller is engineered to meet the demanding needs of fine chemical and pharmaceutical industries. Featuring a conical design and integrated screw mixing, it ensures gentle yet thorough drying of thermo-sensitive materials. The MCV-S operates under ultra-low vacuum conditions (<1 mbar), ideal for applications such as amino acids, antibiotics, and food additives. With capacities ranging from 30 to 10,000 liters, it offers flexible throughput for scaling operations. Designed in accordance with ASME VIII div.1 and EN-13445, the dryer meets strict cGMP and FDA requirements, ensuring compliance for sensitive pharmaceutical processes. Enhanced by options for ATEX certification and CIP/SIP systems, the dryer supports a seamless integration into existing production lines, reducing downtime with efficient cleaning protocols. Constructed with polished stainless steel, it provides high corrosion resistance and durability. Customizable features, including powder retention filters and lump-chopping choppers, offer tailored solutions for complex processing needs.
