Fresh tomatoes arrive at receiving line on trucks and are unloaded into a collection channel. The continuous circulation of water transports the tomatoes to the roller elevator and then leads the raw material to the sorting station.

After the raw material has been rinsed under a stream of clean water, at the sorting station, the staff remove stems, damaged tomatoes and tomatoes that are too small - which will all end up in the waste. Tomatoes suitable for processing proceed to the grinding station. At this stage, the pulp is pre-heated to 65–75°C for the Cold Break process, or to 85–95°C for the Hot Break process.

With the help of a pump, the heated tomato pulp is led to the extraction unit, which consists of two operating stations: a pulper and a refiner. Two products leave the extraction unit:

• the refined juice, for concentration;
• waste, heading for disposal.

At this point, the refined juice is collected in a large tank, which feeds the evaporator continuously.

The juice inside the evaporator goes through several stages - its concentration level will be increased gradually; the desired density will be obtained in the final, or "finisher", stage. The entire concentration process takes place in multi-stage evaporators, sized to preserve the characteristics of the product, and lengthen the working time between successive washings. Fenco evaporators can evaporate from 5,000 to 70,000 l/h of water, processing 150 to 2,000 tons of fresh tomatoes per day.

The concentrate is sent from the evaporator to the sterilization line tank. From here, it is pumped at high pressure first into the sterilizer-cooler, and afterwards, into the aseptic filler, to fill all available sizes into already sterilized bags.
