Industrial Freeze Dryer

Multi-Purpose Industrial Freeze Dryer

Vekuma’s FD-30L freeze dryer is an industrial large capacity vacuum freeze drying equipment that designed for a range of commercial applications such as probiotics, bacterial, dairy, chemicals and bulk materials. Raw products can be solid, fluid, paste, granular and irregular shape, loaded and freeze dried in material trays.

The FDL multi-purpose freeze dryer features rectangular drying chamber which has the highest space using rate and exceptional temperature uniformity. Which result they are particularly fit freeze dry heat sensitive items and guarantee the consistent freeze dried results.

The FD-30L freeze dryer has 29.7m2 shelf area that enable load products, couple with a high performance ice condenser which can collect 300kgs vapors in 2hrs period, condenser lowest -85C. The control system is PLC and touch screen HMI based, capable of auto and semi-auto freeze dry and graphically display main components working status and key parameters, as well as the data logging functionality.
