ZZKD FD-4 freeze dryer with a 4-6 kg batch capacity, four trays, and a condenser temperature of ≤-35°C for lab and small commercial lyophilization.
This equipment is sold for lawful use only. Buyer is responsible for compliance with all applicable regulations.
The ZZKD FD-4 is a freeze dryer designed for lyophilization at volumes above bench-top units. It offers a batch capacity of 4-6 kg across a 0.4 m² drying area, with four trays sized 200×425 mm spaced 70 mm apart.
The unit runs on 110V 60Hz power and draws a rated 1500 W. With a condenser temperature of ≤-35°C and a vacuum level below 15 (Pa), it is suited to labs and processors moving beyond small-scale equipment.
The FD-4 is intended for processors handling materials such as cannabis flower, bubble hash, and extracts.
Freeze drying removes moisture from frozen material through sublimation under vacuum. The product is frozen, then placed under reduced pressure while the condenser, held at ≤-35°C, traps the water vapor drawn off the trays.
