What You Need to Know When Setting Up a Tomato Paste Production Line

Investment in a tomato paste production line is a high value-added facility suitable for export when planned correctly. Incorrect planning, however, means idle capacity and productivity loss. This guide summarizes the headings you need to clarify before making a decision.

1. Calculate capacity backward from raw materials

The capacity of the paste line is defined as "fresh tomatoes processed per day" (e.g. 6–50 tons/day). The amount of tomatoes that can be reliably sourced daily in your region during the season is the actual limit of the line. Approximately 1 kg of 28–30 brix paste is obtained from 6 kg of tomatoes; convert the target finished product amount using this ratio.

2. The brix target determines the equipment

28–30 brix: standard double concentrate; a single/double effect evaporator may suffice.
36–38 brix: triple concentrate; requires a larger evaporation capacity and energy plan.

The brix value required by your target market directly affects the choice of evaporator and steam requirements.

3. Hot break or cold break?

Hot break (85–95 °C) provides higher viscosity and red color; it is preferred for sales to ketchup and sauce industries. Cold break (60–65 °C) offers higher yield. If your target customer is industrial, this decision will affect your selling price.

4. Main equipment items

Washing and sorting lines
Crusher (hot/cold break) and pulper/finisher
Vacuum evaporator (the heart of the line)
Pasteurizer and aseptic/can filling
CIP cleaning system and automation panel

5. Clarify facility needs early

Enclosed area, boiler capacity, process water, electrical power, and wastewater plan must be roughly known BEFORE the offer stage. Any price given without this information is an estimate.

Sample capacity calculation: 25 tons/day of tomatoes

Thinking in numbers clarifies the decision. Let's consider a line processing 25 tons of fresh tomatoes daily:

Finished product: 25,000 kg ÷ 6 ≈ approximately 4,100–4,200 kg of 28–30 brix paste per day
Seasonal production: approximately 250–310 tons of paste in a 60–75 day campaign
Hourly processing: approximately 1,250 kg/hour of tomatoes in a 20-hour campaign shift
Evaporation load: water to be evaporated ≈ 20,800 kg/day → approximately 1,000–1,050 kg/hour evaporation capacity evaporator class
Steam requirement: for a double effect evaporator ≈ 0.55–0.60 kg of steam per kg of water → boiler that will produce approximately 600 kg of steam per hour

These five lines define the evaporator class, boiler capacity, and electrical load simultaneously. Do not compare the equipment list without doing the same calculation with your own tomato quantity.

Technical checklist before the offer

Daily reliable tomato supply (tons/day) and season length
Target brix (28–30 or 36–38) and target market (retail or industrial)
Hot break / cold break decision
Packaging: can, glass jar, aseptic bag, or a combination
Current/planned enclosed area (m²) and ceiling height
Condition of steam boiler, process water, and electrical power
Wastewater (tomato washing water) discharge plan
Off-season operation strategy (is there temporary aseptic stock?)

The 5 most common mistakes we see in the field

Choosing capacity without looking at tomato supply: a facility that sets up a 50 tons/day line but can find 20 tons of tomatoes during the season leaves half of the investment idle. First, secure the agricultural side with contract production.
Choosing a small evaporator and extending the campaign: an evaporation bottleneck leads to fresh tomatoes waiting and quality loss. The evaporator is not a place to save by reducing the line.
Leaving the wastewater permit until the end: tomato washing water is voluminous; the discharge permit and pre-treatment plan is part of the licensing process and can take months.
Making the packaging decision after the line: can, glass, and aseptic filling are entirely different equipment; the "we'll decide later" approach means double investment.
Choosing the boiler independently from the line: if the steam boiler is not sized according to the evaporation load, the line will be marketed with a capacity it can never reach.

Four major items of operating cost

Investment cost is one-time; operating cost recurs every season. The ranking in a paste factory is typically as follows: cost of purchasing tomatoes (by far the largest item), energy (steam + electricity), packaging (can/barrel), and labor. This ranking highlights two engineering decisions: a heat recovery (very efficient) evaporator directly reduces the energy line; a good sorting-washing section that reduces waste rate preserves the raw material line. When comparing offers, look not only at the machine price but also at the steam consumption declaration per ton.

Investment schedule: keeping up with the season

The most ruthless reality of tomato paste investment is the schedule: the tomato campaign is between late July and October depending on the region, and if the line is not ready by that day, it waits until the next season. Plan backward:

2–3 weeks before the campaign: test production and operator training should be finished
2–3 months before the campaign: assembly and piping should be ongoing on-site
6–9 months before the campaign: equipment order should have been placed (evaporator production takes time)
Today: capacity decision, feasibility, and offer process

In practice, this means that investors who decide in the fall/winter can comfortably catch the next season; those who decide in spring risk the season with a tight project. Contract tomato production negotiations are also done in winter — the agricultural side and equipment side schedules should run together.

Sales channel decision: retail or industrial?

The same line can serve two different business models. The retail (branded can/glass) model offers a higher unit margin; in return, it requires brand investment, shelf competition, and extensive distribution. The industrial model (aseptic barrel 36–38 brix concentrate) is sold B2B to ketchup-sauce producers and for export; it has thinner margins but larger volumes and institutional collection. The decision also changes equipment: in the retail model, can sealing and labeling lines are emphasized; in the industrial model, aseptic filling and high brix evaporation take precedence. Many facilities gradually combine both: initial years serving industry with barrels, then retail packaging once the brand is established. This roadmap should be discussed before the offer so that the line is designed ready for the second phase.

Frequently Asked Questions

What does the line do in the off-season?

Facilities producing temporary stock in aseptic bags can process and package paste again in the off-season to operate year-round.

What does the turnkey scope include?

Process design, equipment supply, installation, commissioning, and operator training are all gathered under one responsibility.

How is the brix value controlled during production?

Modern evaporators have inline brix measurement and automatic control options; when the target value is reached, the product is taken automatically. Manual refractometer control may be sufficient for small-scale.

Is a can or aseptic bag more appropriate?

If you are targeting retail sales, then go for can/glass; if targeting industrial sales (ketchup and sauce producers), a 200+ kg aseptic barrel is standard. Both fillings can be combined on one line.
