Vacuum-Fried Snack Line: QS-VF Fryers for Fruit and Vegetable Chips
A vacuum-fried snack line built on the QS-VF fryers: washing, cutting and pre-treatment, low-temperature vacuum frying at 80–100 °C, in-chamber centrifugal de-oiling, and packing — with oil content under 18%.
By the process engineering team at Supreme Beast Intelligent Machinery (Shanghai) Co., Ltd.
Key takeaways
- The QS-VF line is a batch process: QS-VF100 takes 100 kg of raw material per batch, QS-VF150 takes 150 kg and QS-300 takes 300 kg — the QS-VF150 gives 30–50 kg of finished product per batch.
- Frying runs at 80–100 °C under vacuum, and de-oiling happens inside the chamber by centrifuge, so the crisps leave the fryer ready to pack.
- Every capacity figure below is the verified figure for the QS-VF fryer named; anything else is confirmed against your recipe and site.
How does the line work?
Fruit or vegetables are washed, peeled and cut, then fried under vacuum at low temperature, de-oiled in the chamber and packed. The five steps below are the standard vacuum-frying chain.
- Pre-treatment: raw material is washed, peeled and cut to an even size, so every piece fries the same way.
- Vacuum: the chamber is evacuated before frying, which lets the oil stay at 80–100 °C while the water leaves the product.
- Low-temperature frying: the product fries at 80–100 °C under vacuum, controlled by a Delta PLC and MCGS touchscreen.
- In-chamber centrifugal de-oiling: the basket spins inside the chamber after frying, throwing the oil off the product so the finished oil content stays under 18%.
- Packing: the crisps are seasoned where the recipe calls for it and packed into moisture-proof packs.

How is capacity confirmed?
Capacity is confirmed against your recipe and site. The QS-VF100 is verified at 100 kg of raw material per batch, the QS-VF150 at 150 kg of raw material per batch with 30–50 kg of finished product per batch, and the QS-300 at 300 kg of raw material per batch. Finished weight per batch depends on the product and its water content, and frying time per batch varies by product, so daily output is set by your product and the batches your schedule runs — we never quote a fixed time per batch.
Frequently asked questions
Which QS-VF fryer fits a new snack plant?
Start from the raw material you need per batch: 100 kg points to the QS-VF100, 150 kg to the QS-VF150, 300 kg to the QS-300. Tell us your product and daily target and we confirm the model and the number of fryers.
What oil content do the finished snacks have?
Under 18%, with de-oiling done by centrifuge inside the chamber right after frying.
What products can the line fry?
Fruit and vegetable chips are the core products — including durian, okra, mango and similar fruit and vegetables — plus other sliced products your recipe calls for. The fryer, the cutting and the seasoning are matched to the product.
What is the lead time and warranty?
Lead time is about 3 months from order, FOB Shanghai port, with a 12-month warranty. Our engineers commission the fryer on site and train your operators.
