Tomato Paste Making Machine: Composition, Classification, and Industrial Applications

Types of Tomato Paste Making Machines

A tomato paste making machine is a specialized food-processing system designed to transform fresh tomatoes into a rich, concentrated paste used in sauces, soups, and various culinary applications. The process involves several key stages: crushing, milling, cooking, concentration, and packaging. Each stage is handled by a dedicated machine that ensures efficiency, hygiene, and consistent product quality.

These machines are available in both domestic and industrial-scale configurations, allowing for everything from small-batch artisanal production to high-volume commercial output. Understanding the different types of machines involved helps optimize yield, flavor, and shelf life of the final product.

Tomato Crushing Machine

The first critical step in tomato paste production: breaking down whole tomatoes into smaller fragments.

Advantages

• Efficiently processes large volumes of raw tomatoes
• Equipped with rotating knives and squeezing mechanisms for uniform crushing
• Optional homogenization feature for consistent texture
• Reduces preparation time before milling

Limitations

• May require pre-washing to remove debris
• Not suitable for removing seeds or skins
• Blades may need regular maintenance

How it works: Tomatoes are fed into a hopper where motor-driven blades or discs rotate at high speed. The centrifugal force and mechanical pressure crush the tomatoes against a perforated screen, allowing the broken pulp to exit through the discharge outlet while larger chunks are further processed.

Tomato Milling Machine

Refines crushed tomatoes by separating pulp from seeds and skins to produce smooth, seedless puree.

Advantages

• Effective separation of seeds and skin using precision screens
• Produces high-quality, smooth pulp ideal for pasteurization
• Available in both manual (domestic) and automated (industrial) models
• Improves final paste clarity and texture

Limitations

• Screens can clog if tomatoes are overripe or fibrous
• Requires periodic cleaning to prevent bacterial buildup
• Higher energy consumption in industrial units

How it works: Crushed tomatoes are loaded into the hopper and pushed toward a rotating milling plate equipped with sharp blades. Centrifugal force drives the mixture against a perforated screen—pulp and juice pass through, while seeds and fibrous skin are ejected separately. This results in a clean, homogeneous puree ready for cooking.

Cooking & Concentration Machine

The heart of the operation—cooks and thickens tomato puree into concentrated paste through evaporation.

Advantages

• Concentrates flavor and increases Brix level (sugar content)
• Destroys harmful microorganisms through controlled heat
• Vacuum evaporators preserve nutrients and color
• Faster processing with spreader or pan cook designs

Limitations

• High energy and maintenance costs
• Requires skilled monitoring to avoid scorching
• Large footprint in industrial setups

How it works: The puree is heated in large kettles, vacuum evaporators, or spreader cookers. In vacuum systems, steam heats the jacket around the chamber, lowering boiling point and preserving quality. Water evaporates under reduced pressure, leaving behind a thick, flavorful paste. Spreader cookers increase surface area for rapid, even heating, often using a screw mechanism to move paste through heated zones.

Vacuum-Sealing Machine

The final step: packaging the paste to extend shelf life and maintain freshness.

Advantages

• Significantly extends shelf life by removing oxygen
• Prevents microbial growth and oxidation
• Preserves color, flavor, and nutritional value
• Compatible with various packaging formats (pouches, cans, jars)

Limitations

• Initial investment can be high for automated models
• Sealing strips require regular replacement
• Packaging material must be heat-resistant and airtight

How it works: After cooling, the concentrated paste is filled into containers or flexible pouches. The vacuum pump extracts air from the package, and heated sealing bars fuse the edges shut. This airtight environment prevents spoilage and allows safe storage for months without refrigeration.
