Pilot Plant to Full-Scale Line

Key takeaways

• A pilot must prove three things: the recipe works at scale, the batch output matches the plan, and the packed product is the same across batches.
• Pilot-scale machines are the small models of the same family — QS-FD-20 at about 200 kg per batch and QS-VF100 at 100 kg of raw material per batch.
• Scale-up is mostly supply and floor: raw material per day, utilities at peak load, packing capacity and cold or dry storage must all grow with the line.

How do you move from pilot plant to full-scale line?

Run the pilot on the small model of the same machine family, measure the batch output and the yield on your own product, freeze the recipe and the pack format, then scale the line by adding batch capacity or flow — and scale the supply, utilities and packing with it. A pilot that changes the recipe every batch proves nothing.

This guide is for food producers moving from trials to a first production line, or from one line to a larger one, in freeze-dried food, vacuum-fried snacks, dairy, juice and tomato paste.

What must a pilot prove?

Three things, in order: the recipe works at scale, the batch output matches the plan, and the packed product is the same across batches.

First, the recipe. The pilot runs the real recipe — the real fruit, the real milk, the real seasoning — at a real batch size, not a laboratory sample. If the product changes between the laboratory and the pilot, the pilot is measuring the wrong thing, and the full-scale line will inherit the error.

Second, the batch output. Measure how much finished product each batch gives, on your product, and write it down as a range. The QS-VF150 gives 30–50 kg of finished snacks from 150 kg of raw material per batch; your product will sit somewhere in a range of its own, and that range — not a single hopeful figure — is what the full-scale plan is sized from.

Third, consistency. Run several batches and compare colour, texture, pack weight and oil content where it applies — under 18% for vacuum-fried snacks. A product that varies batch to batch costs more in rework than the pilot saved.

Which machines run the pilot?

Run the pilot on the small model of the same family you will scale to, so the trial measures the real process instead of a different machine.

For freeze-dried food, the pilot dryer is the QS-FD-20: 20.16 m², 84 trays, 35 kW, about 200 kg per batch. The full-scale dryer is the QS-FD-100 at about 1 tonne per batch, or the QS-FD-200 at about 2 tonnes. Same chamber material and four-zone heating to ±0.1 °C across the family, so the pilot programme transfers.

For vacuum-fried snacks, the pilot fryer is the QS-VF100 at 100 kg of raw material per batch. The scale-up is the QS-VF150 at 150 kg per batch, giving 30–50 kg finished per batch, or the QS-300 at 300 kg per batch. Same 80–100 °C range and in-chamber centrifugal de-oiling, so the programme transfers.

For liquid lines — dairy, juice, tomato paste — the pilot is the smallest listed line in the family, and the scale-up is the larger listed line at 1–10 T/H or the size your volume needs. The pilot proves the recipe and the pack format; the full-scale line proves the volume.

What changes when you scale up?

Everything around the machine grows with it: supply, utilities, packing, storage and people. The machine is the easy part.

1. Raw material: a full-scale line eats its supply every day. Eight batches of a QS-VF150 need 1,200 kg of prepared raw material a day. Contract the supply before the line arrives, and check the grade and the cut, not just the tonnage.
2. Utilities at peak load: steam or hot water, chilled water, power and drainage are sized from the moment everything runs at once, not from the daily average. A freeze dryer draws about 60% of its listed power in actual running — size the supply from that draw and your hours.
3. Packing: the filler and the packing team must keep up with the new output, or finished product will pile up unpacked. Match the packing line to the finished kilograms per shift, not to the raw intake.
4. Storage: cold rooms for dairy and juice, dry storage for snacks and freeze-dried food, sized to the finished output between dispatches.
5. People: operators per shift, a trained person for cleaning and changeovers, and a spares shelf so a worn seal does not stop the line for a week.

Walk the scale-up as a list, not as a feeling: for each item above, write the number the full-scale line needs and the number the site can supply today. Every gap on that list is a job to close before the order, not after delivery.

From pilot result to order

Order when the pilot has frozen the recipe, the pack format and the batch output range — and the supply, utilities and packing gaps are closed on paper.

Our commercial terms are the same for pilot-scale and full-scale machines: lead time about 3 months from order, FOB Shanghai port, payment 50% deposit and 50% before shipment, and a 12-month warranty, with installation and commissioning by our engineers on site and operator training included.

Send us the pilot results with the order: product, batch output range, pack format, daily volume target and power supply. We return a flow diagram, equipment list and priced proposal — and the pilot machines stay as the trial line for the next product.
