Industrial Freeze Dryers
Freeze drying keeps the shape, colour and flavour of the fresh product — and a shelf life measured in months, not days. Three models cover 200 kg to 2 tons per batch.
One chamber, four controlled stages
Trays go in, dried product comes out. Freezing takes place inside the chamber — no separate pre-freezing room is needed.
- Loading — product on trays, front-door loading, wet and dry products kept separate.
- Freezing & primary drying — ice sublimates under vacuum at −60 °C cold trap.
- Secondary drying — bound moisture removed, 4-zone heating to ±0.1 °C, max 80 °C.
- Packing — dried product packed straight from the chamber.
Three models, one platform
Same control system, same chamber build, same process — sized to your batch.
