Freeze Dry Equipment
Industrial — FD200: Freeze Dryer
The range of Cuddon’s freeze dry equipment was designed after consideration of the factors necessary for pharmaceutical and general purpose freeze-drying. The Model 200 is the first in our range of general purpose commercial freeze dry equipment. The Model 200 is capable of drying most products using a proven 24-hour drying cycle.
The Model 200 is essentially a smaller version of our 300 model freeze dry equipment and shares many similar features.
Description:
- Heating Plates/Shelves: This range of freeze dry equipment features plates fabricated from type 304 stainless steel, which allow an even distribution of the heating or cooling medium. The shelf spacing can be factory set at manufacture to suit individual loading as per the clients’ product needs if necessary. Two sets of type 316 stainless steel product trays are supplied.
- Vapour Condenser: The vapour condenser in our freeze dry equipment is manufactured from type 304 stainless steel tube. The assembly is bolted as a permanent fixture. The coil is refrigerated by direct expansion via a thermostatic valve and distributor.
- Defrosting: Defrosting the ice after a product cycle is by water. Hot water is recommended to assist in rapid defrosting. Heat recovery for water heating can be offered as an option.
- Refrigeration: The refrigeration compressor is Bitzer semi-hermetic, or similar, matched to a system fitted with oil separator, suction accumulator, filters and all necessary safety devices for correct operation. The system will allow refrigeration of the product plates prior to drying. The Model 200 freeze dry equipment is fitted with a water-cooled refrigerant condenser, and water control valve. Ice vapour coil design temperature is -40 deg. Celsius.
- Vacuum System: The rotary vane vacuum pump is connected to the chamber by heavy-duty PVC lines and pneumatic isolating valve. The exhaust of the pump is vented to the exterior of the building. The pump is equipped with a gas ballast facility.
- Heating System: The heating fluid is glycol based and is pumped by a centrifugal pump through a circuit, which allows immersion elements to heat or refrigeration to cool the fluid that is circulated through the plates. Energy is supplied on demand of the electronic load controller.
