- Freeze-dried product with preserved structure and properties
- Type:
- Laboratory / small-scale vacuum freeze drying
- Cold Trap:
- Down to -80°C

Round Freeze Dryer
Categories: Freeze Dryer, Commercial Freeze Dryer, Industrial Freeze Dryer
Maximize Output with Cylindrical-Chamber Freeze Drying:
The Round Freeze Dryer uses a cylindrical chamber that maximizes space usage for large-batch freeze drying at industrial scale. Built to handle big batches without compromising quality or efficiency, it helps companies expand freeze-drying capacity for pharmaceuticals, biological samples and food products while minimizing waste.
- Input:
- Pharmaceuticals, biological samples, food products (large batches)
- Output:
- Freeze-dried product with extended shelf life
- Temperature:
- Adjustable -50°C to -80°C
- Design:
- Cylindrical high-capacity chamber

Cabinet Freeze Dryer
Categories: Freeze Dryer, Industrial Freeze Dryer
State-of-the-Art Cabinet Freeze Dryer for Industrial Use:
This Cabinet Freeze Dryer is crafted to extract moisture efficiently from a wide array of products. Using a freeze-drying technique, it lowers temperatures to optimal levels and converts moisture directly from solid to vapor — ensuring top-notch preservation and quality without a liquid phase.

Discrete-Batch Drying Across Tray, Vacuum and Freeze Designs
The CT-C hot air circulation tray dryer, ZPG vacuum rake dryer, FZG static vacuum cabinet dryer, SZG double cone rotary vacuum dryer and FG vertical fluidized bed dryer all process discrete batches, as do the full freeze dryer range (Pilot, Benchtop, Round, Cabinet, Home Food).
Why Batch Drying Fits Certain Production Needs
Suits smaller production volumes or frequent product changeovers where continuous processing isn't justified. Gives precise control over drying time and conditions for each specific batch. Common for pharmaceutical, specialty chemical and R&D applications where batch traceability matters.
