Hot Filling Production Process Of Juice Beverage

The hot filling production process of juice beverages is a production method that ensures that the beverage is filled at a local temperature to achieve the purpose of sterilization and extend the shelf life. The following is a detailed production process of hot filling beverages:

1. Dilution: Add purified water to the thawed concentrated juice according to the formula requirements. This step is to adjust the concentration of the juice to meet the product standards.

2. Filtration: Remove suspended matter and impurities in the juice through filtering equipment to ensure that the diluted juice is clear and transparent. This is one of the key steps to ensure product quality

3. Homogenization: Homogenize the diluted juice to make it more uniform and stable. The homogenization pressure is generally required to be between 20 and 25 MPa.

4. Sugar dissolving and filtering: Add an appropriate amount of water to the sugar dissolving tank, and add white sugar to dissolve according to the formula requirements. Diatomaceous earth filtration is generally used for sugar solution filtration to ensure the purity of the sugar solution. The dissolution and filtration process of other auxiliary materials is similar to that of white sugar.

5. Mixing: Pump the diluted juice, dissolved and filtered sugar solution and auxiliary materials into the mixing tank, mix them evenly, and make up the volume. Then, add flavors and (or) pigments according to the formula requirements and stir evenly.

6. Filtration: Filter the prepared liquid again through the filter barrel to thoroughly remove possible floating objects and impurities to ensure the transparency and uniformity of the product.

7. Sterilization: The filtered liquid is sterilized by UHT (ultra-high temperature instantaneous) sterilizer. The sterilization conditions are usually 130~135℃ for 4~6 seconds. During sterilization, ensure that the steam pressure supplied to the sterilizer is not less than 0.8MPa. This step is the key to ensure the sterility of beverages.

8. Bottle washing: The bottles are washed by bottle washing machines to remove possible dust, dirt, etc. The pressure of pure water for washing is not less than 0.4MPa to ensure the cleaning effect. Bottle washing machines often form a "three-in-one" installation machine with filling and capping equipment.

9. Filling: Fill the sterilized liquid into the bottle at a temperature of about 90 degrees. The temperature during filling is required to be no less than 90℃, and the temperature in the bottle after filling is no less than 85℃. This step ensures the filling volume is accurate and avoids splashing of liquid.

10. Capping: After filling, capping should be performed immediately. When capping, adjust the torque of the capping head to ensure a tight seal. The capped products need to be inspected by light and the products that are not properly capped should be removed.

11. Bottle overturn sterilization: After hot filling, the products are immediately passed through the bottle inverting machine to invert the bottles. This step is to allow the residual temperature of the liquid after filling to sterilize the bottles and caps to ensure product quality.

12. Cooling: The inverted products are cooled through a cooling tunnel to quickly reduce the temperature of the products to 38+2℃. This step is to prevent the product from deteriorating due to long-term high temperature.

13. Light inspection: Let the product pass through the light inspection machine to check whether there is dirt and impurities in the bottle, and whether the bottle seal is intact, etc., to ensure that qualified products enter the next step.

14.Printing and labeling:Print the production date and batch number on the bottle, and then label it with a labeling machine. Choose one or more labels according to product requirements.

15.Packaging and warehousing: After the above steps, the qualified products are packaged and sent to the warehouse for storage. During the packaging process, the integrity and aesthetics of the product packaging must be ensured.

During the entire production process, the parameters and conditions of each link need to be strictly controlled to ensure product quality and production efficiency. At the same time, the equipment needs to be maintained and serviced regularly to ensure the normal operation of the equipment and extend its service life.
