Fruit & Vegetable Crisps VF Vacuum Frying Turnkey Line
Gentle 80-100℃ negative-pressure frying for low oil content, maximum crispness and natural color — the benchmark of healthy snacking.
Industry Pain Points & the Xinlianxing Answer
Conventional Process Drawbacks
- Darkened, unappealing product
High-temperature frying caramelizes and darkens fruit & veg slices, destroying natural color and shelf appeal.
- Oil content above 30%
Atmospheric frying typically leaves oil content above 30% — greasy texture that fails healthy-snacking expectations.
- Severe nutrient loss
High heat destroys vitamins and heat-sensitive nutrients, erasing the product's health claims.
- Harmful by-products
Repeatedly overheated oil degrades rapidly, raising the risk of acrylamide and other harmful compounds.
The Xinlianxing VF Vacuum Frying Answer
Under negative pressure the boiling point of water drops, so moisture evaporates quickly while oil stays at a gentle 80-100℃, slowing oil degradation dramatically. Combined with micron-level vacuum control and high-efficiency inline dynamic de-oiling, finished oil content is compressed to an industry-leading low — locking in natural color and flavor.
- Negative pressure · gentle 80-100℃ frying
Dual closed-loop control of vacuum level and oil temperature slows oil degradation and preserves natural color and taste.
- Micron-level vacuum control
Precise vacuum-curve management ensures uniform crispness across large batches.
- High-efficiency inline dynamic de-oiling
Inline dynamic centrifugal de-oiling right after frying brings oil content down to an industry-leading low.
One Turnkey Line, from Raw Material to Packed Product
Pretreatment, VF frying, de-oiling and packaging seamlessly connected — Xinlianxing delivers line planning, equipment manufacturing, installation, commissioning and training as one turnkey package.
