How to Plan a Food Processing Line

Key takeaways

• Start with the product list and the daily volume, then convert daily volume into hourly flow using effective production hours after cleaning.
• Draw the process flow before choosing machines: every step in the flow needs a machine, a buffer and a cleaning connection.
• Size utilities at peak load, leave floor space for the next module, and confirm every capacity against your recipe and site — never against a brochure figure alone.

How do you plan a food processing line?

Define the products and the daily volume, draw the process flow from raw material to packed product, size each machine from the hourly flow, then design utilities, layout and cleaning around those flows. A well-planned line matches every machine so no single step becomes the bottleneck.

This guide works for dairy, juice, tomato paste, fruit and vegetable, plant-based and snack lines alike. The examples use equipment from our own catalogue, so every figure you see here is a listed figure from a product page on this site.

What do you need to define before choosing machines?

Three things decide everything downstream: the product list, the daily volume for year one and year five, and the pack formats. A line that makes one product in one pack is a different machine from a line that makes four products in three packs, even at the same tonnage.

For each product, note the raw material, the finished pack and the volume per day — for year one and year five. A line that cannot grow will be replaced, not expanded; the cheapest growth is floor space and pipe connections left ready from the start.

Next, list the constraints of the site: floor area and height, power supply, steam or hot water, water and drainage, and cold storage. If the site cannot supply a utility, the line design must say so before the order, not after delivery.

What is the standard process flow?

Every food line follows the same skeleton: reception, preparation, core process, finishing and packing, with cleaning running through all of it. The machines change with the product; the skeleton does not.

1. Reception: raw material arrives, is checked and stored — milk chilled to about 4 °C, fruit washed and sorted, soybeans soaked.
2. Preparation: the raw material is made ready — milk separated and standardized, fruit peeled and cut, soy ground and filtered.
3. Core process: the step that makes the product — pasteurization, evaporation, fermentation, freeze drying at −60 °C, or vacuum frying at 80–100 °C.
4. Finishing: cooling, blending, seasoning or de-oiling.
5. Packing: filling into bottles, cartons, cups, pouches, drums or sachets, then labelling and storage.
6. Cleaning: every product-contact circuit is cleaned in place between runs.

Draw this flow as a diagram before you ask for prices: each box in it becomes a machine, a tank or a conveyor, and any box without a machine is a gap in the quote.

How do you size equipment from daily volume?

Hourly flow equals daily volume divided by effective production hours. Effective hours are the hours left after cleaning, start-up and changeovers are taken out — often one to two hours a day less than the shift length.

For a continuous line, the arithmetic is direct: 20,000 litres a day over two shifts (16 hours) minus about 2 hours for cleaning gives 14 effective hours, or about 1,430 litres per hour — so a 2,000 L/H pasteurizer gives headroom. Specify 10–20% above the calculated flow.

For a batch line, the arithmetic is batch size times the batches your schedule runs. A QS-VF150 takes 150 kg of raw material per batch and gives 30–50 kg of finished product, so four batches gives 120–200 kg. A QS-FD-100 takes about 1 tonne per batch. Always state the batch count when you ask for a quotation.

Size buffers so the line never waits: storage that lets intake continue while the line is cleaned, and two tanks where one must be cleaned while the other runs. Match each machine to the flow beside it, or the line queues at the smallest one.

Which utilities and layout decisions matter most?

A line needs heat, cold, power, water, air and drainage, each sized from the peak simultaneous load — not the daily average. Steam or hot water serves heating and cleaning; chilled water serves cooling; refrigeration serves cold rooms; compressed air serves valves and fillers.

Layout follows the product in one direction: raw material in at one end, finished goods out at the other, raw and finished zones kept apart, and the high-care filling area under controlled entry.

Two layout decisions are hard to fix later: floor space for the next product module, and a drain and power point where the next machine will stand. We leave both ready when we lay out a line.

What should the quotation cover?

A complete quotation covers the machines, the flow diagram, installation and commissioning, operator training, spare parts and the warranty — with the commercial terms in the same document. Our terms are: lead time about 3 months from order, FOB Shanghai port, payment 50% deposit and 50% before shipment, and a 12-month warranty.

Prices are quoted per configuration, and only verified figures appear in them. The QS-FD-100 freeze dryer, for example, is USD 238,645 for the standard round-chamber model and USD 328,135 for the high-specification square-chamber model. Where a machine has no listed capacity, the quotation sizes it from your recipe and site rather than carrying a catalogue figure forward.

Ask for the delivery scope in writing: machines, tanks, utilities connections, installation, commissioning, training and spares. A quotation that lists these leaves no argument for later.
