Tomato Paste Processing Line

Sunshine Machinery (Shanghai) Co., Ltd. designs and builds complete Tomato Paste Processing Line manufacturer systems that take fresh tomatoes through receiving, washing, sorting, crushing, pre-heating, pulping, multi-effect vacuum concentration, UHT sterilization and aseptic bag filling. Each line is configured around the Brix target, break type, viscosity requirement and packing format of the project, with capacity from 0.5 to 75 tons per hour of fresh fruit input.

Our engineering background comes from the former Qianwei Machinery Factory of Shanghai Light Industry Machinery Group, and our process team works with Italian and international technology partners on low-temperature concentration, hot-break and aseptic filling. Among Tomato Paste Production Line Manufacturers, we supply the line as a coordinated process, not a set of separate machines, so that extraction yield, colour, viscosity and microbiological stability are controlled from the first wash tank to the filled aseptic drum.

What the Line Produces

As a Tomato Paste Processing Line manufacturer, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

The line is built for tomato paste in the 28–38% concentration range, with cold-break and hot-break configurations available according to the viscosity and colour profile required by the end market. The same process platform handles strawberry, blueberry, raspberry, mulberry and chilli pastes and concentrates, which allows a plant to extend its season beyond tomato.

• Final product: tomato paste and other fruit or vegetable concentrates, packed in 220 L or 1000 L aseptic bags.
• Raw material: fresh tomato with no minor ingredients added; the process is purely physical.
• Break options: cold-break for high colour retention, hot-break for high viscosity and body.
• Output formats: aseptic bag-in-drum as standard, with bag-in-box and other filling formats available through our filling range.

Process Stages and Equipment Scope

Each stage has a defined duty in the process, and the equipment is sized from the fresh-fruit input rate and the evaporation load rather than from a fixed catalogue model. The table below shows the standard sequence and the function of each unit.

Key Machines in Our Range

Plants upgrading or expanding an existing process often look to Tomato Paste Processing Line Suppliers for individual units, so the core units of the tomato line are also supplied as standalone machines. Each is engineered to integrate with the upstream and downstream equipment already on site.

Where a plant also processes other crops, the same engineering approach is applied to our mango puree processing line and peach, apricot and plum puree line, and multi-fruit combined lines can be designed around the raw material available locally.

Capacity, Accuracy and Operating Boundaries

Capacity is quoted as fresh tomato input, and the evaporation stage is sized to the water load that must be removed to reach the target Brix. This is why two projects with the same hourly output can require different evaporator areas and different utility demands.

• Capacity range: 0.5–75 t/h fresh fruit input for full lines; project scales from 200 kg/h pilot units to 50 t/h industrial plants.
• Concentration: 28–38% tomato paste as standard, with other Brix values set by the product specification.
• Sterilization control: tube-in-tube temperature is held accurately to protect viscosity and colour indices batch to batch.
• Energy: multi-effect evaporation and the patented sterilizer design reduce steam and power demand compared with single-effect and conventional tubular arrangements.
• Hygiene: CIP and SIP are available for the sterilizer and aseptic filler together, synchronized in one sequence.

Controls and Automation Integration

The line runs on a fully automatic PLC control system, with main electrical components from SIEMENS, SCHNEIDER or other reliable international brands. Automation covers the wash and sort feed, crush and pre-heat temperature, evaporator concentration loop, sterilization temperature and aseptic filling sequence.

Control philosophy is kept deliberately simple: operators see the parameters that decide product quality, and maintenance access is designed into the panel and instrument layout. Where a line must connect to an existing plant SCADA or reporting system, the interface scope is agreed during engineering so that signals, alarms and production records match the plant standard.

Configuration Options

We configure each line from the product specification backward, following the principle of advanced process flow, simple equipment structure, reliable running and saved energy. The main choices that shape a proposal are listed below.

Manufacturing, Testing and Acceptance

We implement full-process quality management across design, fabrication and assembly. Before delivery, every line undergoes complete trial operation and water debugging so that pumps, valves, instruments and the control sequence are proven together rather than machine by machine.

Acceptance is planned with the customer: the test protocol covers run stability, temperature and concentration control, CIP/SIP sequence and aseptic filling integrity. Documentation, spare parts lists and operator training are prepared alongside the equipment so that the plant can take over the line with its own team.

Installation, Commissioning and Service

Our engineers provide on-site installation guidance, commissioning and operator training. After commissioning, one or two engineers can remain on site to support the first production run, and annual pre-season visits cover inspection, maintenance and technology upgrades.

• Plant planning: layout, building planning and utility requirements are reviewed during the in-sale stage.
• Spare parts: accessories and wear parts are supplied so production can continue through the season.
• Remote support: remote diagnosis and repair guidance for on-site faults, with rapid response to breakdowns.
• Upgrades: modernization of older equipment and process improvements between seasons.

Information We Use to Configure Your Solution

A proposal is prepared from the working point of the plant, not from a standard model list. The following inputs let us size the evaporator, sterilizer and filler correctly and give a realistic budget and utility plan.

• Fresh tomato input rate in t/h and the planned operating hours per season.
• Target Brix, break type and viscosity or colour specification of the finished paste.
• Packing format and container size, plus the aseptic filling capacity required.
• Available steam, power, water and cooling capacity at the site.
• Site layout, building dimensions and the position of receiving and dispatch areas.
• Local raw material quality and season length, including any plan for multi-fruit operation.
• Investment budget range and the required delivery schedule.

Frequently Asked Questions

What capacity range can Sunshine supply for a tomato paste line?

We build full lines from 0.5 to 75 t/h of fresh tomato input, with project scales covering pilot units of 50–200 kg/h, mini lines of 200–1000 kg/h, medium plants of 1–5 t/h and large industrial lines of 5–50 t/h.

Can the line produce both cold-break and hot-break paste?

Yes. The pre-heating stage and the evaporator configuration are set to support cold-break, hot-break and different Brix products according to the customer's requirement, and the changeover procedure is covered in operator training.

How is the aseptic filling stage integrated with sterilization?

The tube-in-tube sterilizer and aseptic bag filler share a synchronized CIP and SIP sequence, so cleaning and sterilization are carried out together before production and between runs. This protects the aseptic condition from the sterilizer outlet to the filled bag.

What filling formats are available for the finished paste?

The standard format is aseptic bag-in-drum in 220 L or 1000 L bags. Aseptic bag-in-box filling is also available from our filling range, and the choice is fixed during configuration based on the container and logistics plan.

Can the same line process other fruits outside the tomato season?

The process platform handles strawberry, blueberry, raspberry, mulberry and chilli pastes, and we design multi-fruit combined lines around the raw material available locally to maximize equipment utilization across the year.

How do you support installation and the first production run?

Our engineers guide installation and commissioning on site, train the customer's operators, and can remain on site with one or two engineers to assist initial production. Annual pre-season visits then cover inspection, maintenance and technology upgrades.
