Unit applies a thin coating of frozen product evenly around the inside of a freeze-drying flask, permitting a greater volume of material to be quickly and efficiently processed during each freeze-drying run. These refrigerated units provide a simple and safer method of pre-freezing multiple flasks at one time and producing the thin shell inside. The freeze dry cycle is shortened because moisture does not have to migrate through the ice interface and a thick layer of already dried product. Bath is mounted in a streamlined, compact cabinet that allows capacities of up to two each 1200 mL flask and up to four each 40 mL flasks at one time. Flask are automatically rotated by speed controlled, motor driven rollers in a refrigerated bath containing alcohol or any other freeze resistant fluid.
