The Hosokawa Active Freeze Dryer
A unique technology in the field of freeze drying (lyophilisation)
Drying technology is a major activity within the powder-processing division of the Hosokawa group. Hosokawa has long enjoyed an outstanding reputation based on the Vrieco-Nauta conical batch vacuumdryers, which have set a new market standard for drying technology. The vast, specialized know-how built up by the group has led to the development of a new type of dryer, the Active Freeze Dryer™ (patent pending).
The Hosokawa Active Freeze Dryer™ enables to produce at low temperature and low pressure a lump-free, free-flowing, freeze dried product (see picture). The Active Freeze Dryer™ also has a better heat transfer rate due to the continuous mixing of the product, resulting in shortening the drying process. Furthermore the freezing step is simplified because it can be done in the same vessel instead of having a separate freezing unit, which results in easy handling of the product compared to the tray dryer equipment. The Active Freeze Dryer™ can also be used in continuous operation. Since the dried product is released from the frozen material during the drying process, these dry particles can be collected separate from the actual dryer.
