- Preheating tomato pulp. For cold-pressed tomato puree, a temperature of 55-60℃ is needed for 10-15 minutes. For the break tomato paste, a temperature of up to 85-90℃ is required for 10 to 15 minutes.

- Crushing stage: Apples and pears undergo a crushing process to a size of 3-9 mm. Crushing takes place by roller squeezing and blade cutting. As you know, raw fruit can darken under the air. To avoid this, special membranes, valves, and solutions of ascorbic and citric acids are used.
- Belt press juicer stage: This type of juicer can produce 70-90% juice.
- Ultrafiltration process: This process allows the manufacturer to achieve the purity of the juice with minimal loss of flavor and nutrients.
- Enzymatic processing process: At this stage, enzymes may be added to the juice to complete the clearance process of the juice.
- Concentration process: Concentration takes several minutes with a temperature of 55-60℃. This is the optimal time and temperature so that the juice does not lose its beneficial properties.
- Sterilization and Spill: The processing will depend on what type of finished product filling will be used.
