1. Project Requirements and Production Goals
The project is based on fresh tomatoes as the raw material, with a planned processing capacity of 200–300 kg per hour.
At this production scale, equipment selection should consider the characteristics of fresh tomatoes, the required processing steps, the desired puree consistency, and the final packaging format.
The proposed line combines washing, pulping, screening, concentration, heating, filling, and labeling equipment. These machines are intended to work together as a processing system, with pumps, buffer tanks, piping, and supporting equipment connecting the main stages.
The solution uses a primarily semi-automatic configuration. This allows operators to participate in material handling and packaging operations while mechanical equipment performs the main processing tasks.
Before final equipment commissioning, the actual processing parameters should be confirmed according to tomato variety, raw material condition, target product specifications, and local utility conditions.
2. Tomato Puree Production Process
The proposed production line includes the following main processing stages.
Step 1: Fresh Tomato Washing
Fresh tomatoes enter a bubble washing machine equipped with a lifting system.
The machine uses bubbling action to agitate the tomatoes in water, helping remove surface dirt and impurities. The lifting system then transfers the cleaned tomatoes to the next processing stage.
The specified washing machine has a nominal model capacity of 0.5 t/h and is constructed from SUS304 stainless steel.
Its listed capacity is higher than the project’s target raw material throughput of 200–300 kg/h. Actual operating throughput will depend on feeding conditions and the overall line configuration.
Step 2: Tomato Pulping and Refining
After washing, the tomatoes are processed by a double-stage pulping machine.
The equipment is designed to separate the tomato pulp from unwanted coarse materials, helping produce a more uniform intermediate product for further processing.
The proposed pulping machine is made of SUS304 stainless steel. Its two stages have listed motor powers of 5.5 kW and 4 kW, respectively, with a nominal model capacity of 0.5 t/h.
The appropriate screen configuration and processing settings should be confirmed according to the required puree texture and the characteristics of the raw tomatoes.
Step 3: Buffering, Pumping, and Screening
After pulping, the tomato pulp passes through buffer tanks, sanitary centrifugal pumps, and a vibrating screen.
The buffer tanks help provide intermediate holding capacity between processing stages, while the pumps transfer the product through the system.
The proposed vibrating screen has a diameter of 800 mm and an adjustable screen configuration. It is intended to remove coarse particles and improve the consistency of the processed material.
These components support product transfer and help coordinate the operation of the processing equipment.
Step 4: Tomato Puree Concentration
The proposed line includes a double-effect concentrator with a listed capacity of 500 L.
The concentration stage is intended to reduce the water content of the tomato pulp and help achieve the required product concentration.
A double-effect concentration system uses heat more efficiently than a comparable single-effect arrangement under suitable operating conditions. Actual energy consumption and evaporation performance depend on the equipment design, operating parameters, and product characteristics.
The required final concentration, processing temperature, and residence time should be established according to the intended product specification.
Because the source equipment list specifies the concentrator in liters rather than kilograms per hour of evaporation, its actual evaporation capacity should be confirmed during detailed engineering.
Step 5: Heating and Product Preparation
The proposed configuration includes a 300 L stainless steel jacketed kettle with stirring and wall-scraping functions.
The kettle uses steam heating and is designed to heat and mix the tomato product. Scraping the vessel wall helps reduce product accumulation on heated surfaces and supports more uniform mixing.
A screw pump transfers the product between relevant stages, while a stainless steel pipeline filter provides an additional filtration point before filling.
The exact heating temperature, holding time, and product preparation procedure should be established through process design and validation. These parameters are important for achieving the intended product quality and food safety requirements.
Step 6: Filling Tomato Puree into 300 ml Glass Bottles
The packaging section is designed around 300 ml glass bottles.
The proposed equipment includes a semi-automatic single-head piston filling machine with an adjustable filling range of 50–500 ml. This range covers the specified 300 ml bottle size.
The piston filling mechanism is suitable for products that require controlled volumetric filling. Actual filling accuracy and speed depend on product viscosity, temperature, filling settings, and operator handling.
A semi-automatic capping machine is also included. It is designed for glass bottles with manually loaded caps.
This arrangement is intended for businesses that prefer a relatively simple packaging setup rather than a fully automatic high-speed filling and capping line.
Step 7: Heating Treatment, Labeling, and Coding
The proposed packaging section also includes a stainless steel heating tank, a circular bottle labeling machine, and an inkjet coding machine.
The heating tank has a listed adjustable temperature range of 45–93°C and uses steam heating. The appropriate treatment conditions must be determined through a validated process based on the product’s pH, formulation, packaging, and intended shelf life.
The listed temperature range alone does not establish that the finished product will be commercially sterile or shelf-stable. The complete thermal process, bottle and closure suitability, cooling procedure, and microbiological requirements must be evaluated by a qualified food-processing specialist.
After the required treatment, the labeling machine applies labels to round bottles. The inkjet coding machine can be used to print batch or date information, subject to the final configuration.

4. Why Choose a Semi-Automatic Tomato Puree Processing Line?
For a project processing 200–300 kg of fresh tomatoes per hour, a semi-automatic configuration may be appropriate when the investment budget, available labor, and expected market demand favor a smaller production setup.
Key considerations include:
A production capacity suited to the project
The proposed processing target is 200–300 kg/h of fresh tomatoes. This provides a starting point for planning raw material supply, production scheduling, and equipment selection.
Integrated processing stages
The proposed equipment covers washing, pulping, screening, concentration, heating, filling, capping, and labeling. Integrating these stages helps organize the production process and reduce the need to source every machine separately.
Flexible bottle filling
The specified piston filling machine supports filling volumes from 50 to 500 ml, including the planned 300 ml glass bottle format.
A practical automation level
Semi-automatic filling and capping equipment requires operator involvement. This configuration may be suitable for businesses that prioritize a straightforward operating setup, although labor requirements and actual output must be assessed before purchase.
Room for process optimization
The equipment layout and operating parameters should be finalized after the buyer confirms the target puree consistency, packaging requirements, processing schedule, and applicable food safety standards.
5. Key Considerations Before Starting Tomato Puree Production
Selecting the machinery is only one part of establishing a tomato processing facility. Several technical details should be confirmed before the project moves into manufacturing and installation.
Raw Material and Product Specifications
Tomato variety, maturity, solids content, and incoming quality can affect pulping performance, concentration requirements, and finished product consistency.
The buyer should specify the desired puree characteristics, including final soluble solids or other applicable product quality indicators.
Actual Line Throughput
The washing and pulping machines have listed model capacities of 0.5 t/h, while the project targets 200–300 kg/h of fresh tomatoes.
These ratings do not automatically establish the output of the complete line. The concentrator’s evaporation performance, intermediate holding capacity, heating process, and manual packaging operations may influence overall production capacity.
The complete system should therefore be checked against the expected hourly output and daily production schedule.
Packaging and Thermal Processing
The planned 300 ml glass bottle format requires compatible bottles, closures, filling conditions, and a suitable thermal processing procedure.
The required treatment must be established according to the product formulation and intended shelf life. Commercial production should not begin until the relevant food safety and packaging requirements have been verified.
Utilities and Factory Conditions
The equipment list specifies a 380 V supply for the bubble washing machine and includes a steam generator and steam-heated equipment.
The buyer should confirm local electrical specifications, steam requirements, water supply, drainage, cleaning facilities, and the available installation space. Utility ratings and compatibility should be verified for the complete equipment package.
Installation, Cleaning, and Operator Training
A well-planned layout should provide suitable access for material handling, cleaning, maintenance, and safe operation.
Cleaning procedures, food-contact materials, and operating instructions should be reviewed before production begins. Installation and commissioning arrangements should also be agreed upon with the equipment supplier.
