Description of Each Step for Tomato Processing Line

1. Discharge platform
When fresh tomatoes come, normally with the big truck, if discharge with human, it would be very difficult. So we design the discharge platform and use the water gun to discharge fresh tomatoes from the truck, also use water to deliver fresh tomato to the processing line. And there is another function of the discharge platform, it can pre-wash fresh tomato before processing.

2. Elevator
This machine is used to deliver fresh tomato from outside the building to inside.

3. Washing
Before crushing, need to washing fresh tomato carefully. For washing we can use bubble washing machine and spray washing machine together. If the washing requirement is high, can add more stages of washing. Also for better cleaning effect, we can add ultrasonic cleaning and ozone cleaning.

4. Sorting

After washing, the surface of tomato is clean, we can check the situation of all the tomatoes by eye. And sort out the bad tomatoes by human.

5. Crushing

The crusher is running at the speed of 1470 r/min to crush fresh tomatoes to make sure all the tomatoes are fully crushed.

6. Preheating

The pre-heater is used to heat the product after crusher, the temperature is adjustable, normally from 45℃ to 85℃. This processing step, would help to higher the juice rate for next step, and also can protect the color and testing for final tomato paste.

7. Pulper and refiner

This machine is also running with the speed of 1470 r/min, it causes the centrifugal force and the product will go through the screen, which helps to refine the product. And normally we use double stage of pulper and refiner, the screen of each stage is different, for the first stage the screen would be bigger, and for the second stage the screen would be smaller.

8. Evaporating

The vacuum Evaporator is used for concentrating the tomato paste under vacuum and low temperature. Here we are using Forced Circulation Vacuum Evaporator. Because it’s under vacuum and low temperature, so the test and nutrients would be protected as much as possible. And right now we get the tomato paste, normally the Brix is 28–30 and 36–38.

9. Sterilizing

For tomato paste, we use the tube in tube type sterilizer for sterilizing. The sterilizing temperature and holding time is adjustable. With this machine, we will heat the tomato paste to a very high temperature around 115℃ holding for 30s and then cooling it to ambient temperature immediately. This way also can protect the test and nutrients of tomato paste as much as possible.

10. Aseptic Filling

The aseptic filling machine works together with the tube in tube type sterilizer. It’s a closed cycle. Before production, the cycle will be fully sterilized to make sure of the aseptic environment. And the filling cavity is also protected by steam to make sure the filling environment is also aseptic.
