Pilot plant conical screw dryer

Dries, Mixes, and Tests Powder and Slurry Materials

The BS-pilotDRYⓇ Series from BOLZ Process Technology GmbH is a versatile pilot plant vacuum dryer designed to simulate drying and mixing processes at a pilot scale. It uniquely features a hybrid stirrer system, allowing both conical screw and central shaft drying in a single unit, making it ideal for R&D and scaling up production processes. Primarily used in pharmaceuticals, chemicals, and food industries, it facilitates the drying and mixing of APIs, specialty chemicals, and nutritional supplements. With flexible filling volumes ranging from 10% to 100%, it supports a variety of batch sizes. The unit operates efficiently under a broad pressure range from -1 to +6 bar and offers orbital and central shaft operating temperatures of 160°C and 240°C respectively, ensuring adaptability for diverse processing conditions.

Constructed from robust materials like AISI 316L and Hastelloy C22, it provides excellent corrosion resistance for handling aggressive substances. The system complies with stringent GMP and FDA requirements, providing ease of compliance with industry standards. Its CIP cleaning capability ensures hygiene and minimizes downtime, while a mobile skid design and “plug and use” installation make it operationally efficient. Customizable components, including diverse sensors and sampling valves, enhance monitoring precision and operational safety.
