Variable Temperature Differential Pressure (VPT) Puffing Equipment
Variable Temperature / Pressure-Difference (VPT) Puffing equipment for light, crisp fruit and vegetable snacks — a distinct process from vacuum frying, freeze-drying or hot-air drying.
Applications
- — Fruit pieces
- — Vegetable pieces
- — Light, crisp snack formats
What It Does
Uses a rapid pressure-differential cycle on pretreated (often pre-dried) product to puff it into a light, crisp texture — distinct from vacuum frying, freeze-drying and hot-air drying.
Process Position
Positioned after pretreatment and before grading & packaging, as an alternative to freeze-drying for a different texture profile.
Key Features
- — D1/D2 pressure vessel construction
- — Siemens PLC control
- — Confirmed applicability list for fruit/vegetable products

Frequently Asked Questions
How is this different from freeze-drying?
VPT puffing uses a rapid pressure differential on pre-treated product rather than sublimation from a frozen state — it produces a lighter, crisper texture. See the Technology page for a full comparison.
