A cold-fill juice filling machine is designed to package juices that are filled at ambient or refrigerated temperatures, a process essential for preserving the fresh flavor, color, and nutritional integrity of products that are not thermally processed for shelf-stability. This method is used for Not-From-Concentrate (NFC) juices, cold-pressed juices, and some dairy blends that require refrigeration. The critical challenge is maintaining microbiological safety without heat, which is addressed through two main approaches: clean filling and aseptic filling. A clean-fill system employs stringent hygiene protocols: the juice is lightly pasteurized, the bottles and caps are sanitized with chemical rinses (e.g., peracetic acid) or UV light, and the filling takes place in a positively pressurized, HEPA-filtered environment to exclude contaminants. Aseptic filling is more comprehensive, involving sterile filtration or flash pasteurization of the juice and separate sterilization of packaging materials, with filling and sealing conducted in a completely sterile chamber. Ace-Filling's cold-fill machines are engineered with these principles, featuring sanitary design and often isolator technology to create the controlled environment necessary for producing a safe product with a "fresh-like" quality and an extended chilled shelf life.
