Aseptic processing in food and beverage industry

Aseptic processing  is a processing technique wherein commercially thermally sterilized liquid products (typically food or pharmaceutical ) are packaged into previously sterilized containers under sterile conditions to produce shelf-stable products that do not need refrigeration.  Aseptic processing has almost completely replaced in-container  sterilization of liquid foods, including milk, fruit juices  and concentrates, cream, yogurt, salad dreesing liquid egg, and ice cream mix. There has been an increasing popularity for foods that contain small discrete particles, such as cottage cheese, baby foods, tomato products, fruit and vegetables , soups and rice desserts.

Aseptic processing involves three primary steps: 

Thermal sterilization of the product,  

Sterilization of the packaging material,

Conservation of sterility during packaging

To ensure commercial sterility, aseptic processing facilities are required to maintain proper documentation of production operations, showing that commercially sterile conditions were achieved and maintained in all areas of the facility.

 Any breach of a scheduled process for the processing or packaging system means that the affected product must be destroyed, reprocessed or segregated and held for further evaluation.

 In addition, the processing and packaging system must be cleaned and re-sterilized before processing and/or packaging operations can resume. Packaging equipment and packaging materials are sterilized with various media or combinations thereof

(i.e., saturated steam,superheated steam, hydrogen peroxide and heat and other treatment.

The application of liquid nitrogen in the beverage industry is self-evident. As a key medium in beverages, the aseptic liquid nitrogen dosing (filling)machine plays a very critical role in order to ensure ensure commercial sterility during the filling process. As a packaging equipment used in combination with aseptic filling and sealing machines, aseptic liquid nitrogen dosing (filling) machine have received more and more attention from the beverage industry.
       As a domestic leader in the manufacture of liquid nitrogen machines, Zhoushan Willman Machinery Technology Company has made a breakthrough in the technology of aseptic liquid nitrogen filling machines. Our aseptic liquid nitrogen machines have been successfully operated in the customer’s factory, and the final product meets the customer’s commercial sterility requirements.

If you have requirements for this technology and equipment, you are welcome to communicate with you.
