The requirement of aseptic filling machine for the juice production line process

The requirements of aseptic filling machine manufacturers for the juice production line process are as follows:

1. Dilution: Aseptic filling machine manufacturers dilute the frozen concentrated juice with pure water according to the formula requirements.
2. Filtration: Remove suspended solids and impurities in the juice to ensure clarity after dilution.
3. Homogenization: Aseptic filling machine manufacturers homogenize the diluted juice to make it uniform and stable. The homogenization pressure requirement is 20-25MPa.
4. Sugar dissolving and filtration: This is done in the sugar dissolving tank. Start the stirrer, add an appropriate amount of water, and add white sugar according to the formula. Sugar dissolving can be done by hot melting or cold dissolving methods, and one of them can be selected according to the production process requirements. Diatomaceous earth filtration is generally used for sugar solution filtration. Other auxiliary materials are dissolved and filtered together with the sugar base.
5. Allocation: Aseptic filling machine manufacturers pump the previously diluted juice, dissolved and filtered sugar solution, and dissolved and filtered auxiliary materials into the allocation tank, mix them evenly, and adjust the volume. Add flavors and/or colors according to the formula, and stir well.
6. Filtration: The allocated liquid is filtered again through a filter barrel connected to the pipeline to completely remove any suspended solids or impurities that may exist, ensuring product transparency, uniformity, and no sedimentation.
7. Sterilization: Aseptic filling machine manufacturers sterilize the filtered liquid with a UHT sterilizer. Sterilization conditions: 130-135℃, 4-6 seconds. During sterilization, the steam pressure supplied to the sterilizer should not be less than 0.8MPa.
8. Cleaning: The bottles are thoroughly cleaned of any dust, dirt, etc. that may be present inside the bottle using a bottle washer. To ensure the cleaning effect, the pure water pressure used for cleaning should not be less than 0.4MPa. Bottle cleaning is often combined with filling and capping to form a “three-in-one” filling machine.
9. Filling and capping: There are two methods for filling: aseptic cold filling and aseptic hot filling. To ensure quality, aseptic hot filling is often used for juice and beverage filling, with the requirement that the temperature during filling should not be lower than 90℃, and the temperature inside the bottle should not be lower than 85℃ after filling. The bottles should be capped immediately after filling. Adjust the capping head to the appropriate torque to ensure a tight seal. A “three-in-one” hot filling machine combines bottle washing, filling, and capping.
10. Bottle inversion: The products filled with hot filling are immediately passed through a bottle inverter to invert the bottles, allowing the residual heat of the filled liquid to sterilize the bottles and caps to ensure product quality.
11. Inspection: The products are inspected using a lamp inspection machine to check for dirt, impurities, and any defects in the bottle seal, ensuring that only qualified products move on to the next step.
12. Cooling: The products are passed through a cooling tunnel to quickly lower the temperature to (38±2)℃. This process causes more damage, but requires less investment in hot filling equipment.
