Vacuum Freeze Dryer (FD series)
A vacuum freeze dryer spanning ten frame sizes, for gentle low-temperature dehydration of fruit, vegetable and snack products.
Applications
- — Fruit slices and pieces
- — Vegetable pieces
- — Snack-format freeze-dried products
What It Does
Freezes the product, then removes moisture via sublimation under vacuum — a slower, gentler process than hot-air drying that preserves color, aroma and nutritional content.

Frequently Asked Questions
How is the right model size chosen?
By target batch volume and throughput across the 10 documented frame sizes (FD-2.5 to FD-240).
How does freeze-drying differ from VPT puffing?
Freeze-drying removes water by sublimation from a frozen state; VPT puffing uses a rapid pressure differential. They produce different textures — see the Technology page for a full comparison.
