Freeze Drying Plant of Continuous Radiation Type

The CONRAD™ (Continuous Radiation) freeze drying plant is fully automatic and controlled centrally.

By means of the conveyor system the trays pass into the filling station where the frozen product is dosed into the tray. The trays proceed through the inlet airlock and into the inlet elevator.

When the elevator is filled to its capacity of 15 trays, the whole stack is pushed into the first temperature zone. Subsequently, the stack of 15 trays is pushed by the following stacks through the various zones, each adjusted to give the product the optimal heat treatment.

Finally, the stack arrives at the exit elevator, and the trays are led through the exit airlock to the emptying station where the now freeze-dried product is removed.

After being washed, the empty trays return automatically to the filling station to repeat the process.
