Foster Blast Freezer 17-283 BCT52, 52 kg

Fast, hard pre-freezing is half of a good freeze-dried product. A blast freezer drops product to about −30 to −40 °C quickly, forming small ice crystals that protect cell structure and give better colour, texture and rehydration than slow freezing. It also frees your dryer to sublimate rather than spend hours freezing on-shelf — lifting throughput.

It blast-freezes up to 52 kg per cycle. Match the blast freezer roughly to your dryer's batch load so one pre-freeze run fills one drying batch. If you run several dryers or large batches, size up — pre-freezing should never be the bottleneck.

You can, but slow freezing forms large ice crystals that rupture cells, giving softer, dull, lower-quality results and longer dryer cycles. A blast freezer is the difference between acceptable and premium freeze-dried product, and it pays back in quality and machine utilisation.

Any of them — pre-freezing is a separate upstream step, so a blast freezer works with any tray-batch dryer in the range and any product.
