40.5m2 Production Freeze Dryer
The FD-40L freeze dryer is an industrial large production freeze drying unit, designed to process heat sensitive materials like probiotics, nutritional products, bacteria, enzymes and a range of biological items. The freeze dry machine has 40.5m2 shelf area and a 400kgs/24hrs ice condenser. It features rectangular shape drying chamber which means highest space using rate and superior temperature uniformity acorss the chamber.
