What is the tomato paste production machine?
What is two-stage vacuum evaporation technology?
Technical characteristics of two-stage vacuum evaporation
- Decreasing the cooking temperature to below 65 degrees Celsius preserves the natural color and aroma of the paste.
- Steam heat recovery of the first stage saves energy consumption up to 40% compared to conventional systems.
- Reduction of oxidation in the final product ensures a longer shelf life of the paste.
- Automatic control of pressure and temperature by industrial PLC, errors minimizes human.
Advantages of tomato paste production machine with two-stage vacuum system
1. Preservation of nutritional value
2. Reducing energy consumption
3. Increasing production speed
4. Color quality and high concentration
Low temperature prevents the paste from darkening and preserves its shiny and natural red color. Also, the concentration efficiency increases up to Brix 38 to 40 without burning the surface of the material.
The main components of the tomato paste production machine with two-stage vacuum system
1. Washing and preparation unit
At first, tomatoes are washed by steel strips and pressurized water spray system to remove all contamination. The use of 304 stainless steel in the body and fittings is done according to health standards.
2. Tomato industrial chopper
Clean tomatoes enter the shredder and with acid-resistant steel blades, they are turned into a homogeneous mass with small seeds. A powerful three-phase motor with a power of 5 to 7.5 horsepower guarantees the continuous operation of the device.
3. Pre-heater
In this section, the initial temperature of the material increases to about 85 degrees Celsius so that the destructive enzymes are deactivated and the cell tissue is prepared for better evaporation.
4. First stage vacuum evaporation unit
In this part, tomato juice evaporates under low pressure (about 0.7 bar below atmosphere). The resulting steam is collected in heat exchangers and directed to the second stage.
5. Second stage vacuum evaporation unit
The second stage completes the concentration process so that the final concentration of the paste reaches the desired Brix. The steam of the first stage is used as a renewable energy source in this section, which reduces fuel consumption.
6. Final cooling system
Concentrated paste is cooled in plate exchangers until its temperature reaches 40 to 45 degrees for packaging.
7. Packaging system
The automatic volumetric filling machine puts the paste into glass containers, metal cans, or export barrels. The evacuation system without direct contact guarantees complete hygiene.
The role of Bandar Industrial Group in the design of this device
Bandar Industrial Group, with more than two decades of experience in designing food production lines, has been able to localize the two-stage vacuum evaporation system and optimize it for Iran's climatic conditions.
Port services included
- Custom design of the machine based on the capacity required by the customer
- Made of steel body and components completely anti-acid and anti-corrosion
- Complete installation and commissioning of the line, from washing to packaging
- Offering a valid one-year warranty and supplying parts for up to 10 years
- After-sales service throughout Iran
Competitive advantage of the port
Tomato paste production machines are equipped with an automatic vacuum pressure adjustment system that prevents the product concentration from changing during production. Also, all systems can be connected to industrial monitoring software and remote control is possible.
The general process of designing and building the production line by the port
Step 1: Engineering design
Analysis of desired production capacity and characteristics of consumed tomatoes to determine the dimensions and evaporation power of the device.
Step 2: body construction and assembly
Using 3 to 5 mm thick steel sheet for the main tanks. All welding is done with TIG standard.
Step 3: Performance and vacuum testing
The device is tested in the presence of port experts to check the stability of the pressure and the performance of the evaporation system.
Step 4: Final setup at customer site
Complete line installation, temperature adjustment, and operator training are done by the technical team of the port.
The economic effect of using a two-stage vacuum system
According to the increase in fuel and energy costs in the industry, the use of a two-stage vacuum system can save about 30 to 40% in operating costs.
In addition, by increasing the quality of the production paste, the possibility of exporting to regional markets such as Türkiye, Iraq and Oman is provided for the factories.
Quality control of the output product
The paste produced by Bandar machines is checked in terms of color, concentration, pH and taste according to the national standard of Iran. The color of the paste resulting from the two-stage vacuum process is in the range of bright red and without bitterness caused by high temperature.
Bandar Industrial Group's proposal for small and medium workshops
Bandar Industrial Group also offers semi-industrial versions of the tomato paste production machine with a two-stage vacuum system, which is suitable for workshops with a daily capacity of up to 2 tons. These models have simpler controls, smaller dimensions and lower maintenance costs.
Summary
Tomato paste production machine with a two-stage vacuum evaporation system is a combination of modern technology and modern industrial design that guarantees the quality, economy and stability of the product at a high level.
Bandar Industrial Group with its experienced engineers and advanced equipment, covers all the needs of adhesive production units from the design stage to installation and training.
By choosing the port, buyers can benefit from a device that:
- It has low energy consumption
- It produces export quality paste
- And it has continuous technical support services.
