Commercial Freeze Dryer for Various Industries
Vekuma’s FD-20L freeze dryer is a high performance commercial freeze dryer that designed for a variety of industrial applications. Typical applications include bacterial, yogurt, nutrient and probiotics lyophilization. The machine is designed to process bulk materials, products are loaded and freeze dried in material trays.
The FDL general purpose freeze dryers feature rectangular drying chamber which means highest space using rate and exceptional temperature uniformity. The proven advantages result they are particularly fit freeze dry heat sensitive items and guarantee the consistently freeze dried results.
