Vacuum dryer cabinet for heat-sensitive products

For manufacturers handling heat-sensitive products, achieving precise moisture control and gentle drying is critical, ensuring product quality and consistency throughout processing.

Processes and Dries Heat-Sensitive Products

The DryCab from Bucher Unipektin is an engineered vacuum and freeze dryer cabinet tailored for the food and pharmaceutical industries, adept at handling heat-sensitive products like instant coffee, herbal teas, and fruit or vegetable powders. Utilizing vacuum drying technologies, including freeze-drying (lyophilization), the DryCab minimizes oxidation and contamination while ensuring product quality through gentle drying procedures. Designed to operate within a broad vacuum range of 0.5 to 100 mbar and at temperatures up to 200°C, it accommodates capacities of 1 to 1,000 kg per batch. The system supports automation with PLC and HMI controls, allowing recipe management for consistent, high-quality output. Energy-efficient with options for steam, pressurized water, or thermal oil heating, coupled with steam jet or chilled water condensation for vacuum creation, it effectively reduces operational costs. Constructed with GMP hygiene standards and designed for durability, the DryCab offers seamless integration into existing production lines and ensures high product availability and minimum loss with an automatic 3-step CIP system for thorough cleaning. Customization options are available to meet specific operational needs, supported by engineering expertise from Bucher Unipektin.
