Vacuum drying solution for filter cake or viscous materials
When faced with the challenge of drying filter cake or transitioning viscous pastes to solid form, ensuring efficient heat transfer and minimal energy consumption is essential.
Processes and Dries Solids, Liquids, and Powders
The Cylindro Conical Dryer CCD from the HEINKEL Drying and Separation Group is engineered to handle complex tasks in drying, mixing, and evaporation processes. Its central shaft agitator ensures even distribution and consistent processing of products in varying phases, from liquid to solid. This dryer is effective in industries such as pharmaceuticals, chemicals, and food processing, catering to end-products like active pharmaceutical ingredients, specialty chemicals, and protein powders. With a working volume accommodating 15% to 80% of its capacity, this dryer integrates seamlessly into batch or pilot operations. The equipment supports energy-efficient operations with excellent heat transfer characteristics, owing to its heated helix agitator and pressure-rated vacuum vessel. Available in a range of materials like AISI 316L and Hastelloy C22, it is constructed to withstand corrosive environments and offers ATEX and EHEDG compliance, ensuring safety and regulatory adherence. The inclusion of diverse sensors and CIP/WIP systems facilitates precise monitoring and straightforward maintenance, customizing options available to meet specific process requirements.
