Herbal Beverage Canning and Glass Bottle Retort System

Herbal beverage water-spray sterilization is carried out in a sealed retort system. Heated circulating water is atomized through nozzles into fine droplets and evenly sprayed onto the surface of aluminum cans or other packaging, enabling rapid and uniform heating. During the heating phase, system pressure is precisely controlled to help prevent container deformation. Heat is transferred via a thin water film and gradually penetrates into the product until the cold spot reaches the required sterilization intensity, effectively inactivating bacteria, yeasts, and heat-resistant spores to achieve commercial sterility.

After the holding phase, staged cooling is conducted under controlled pressure to minimize overprocessing and maintain product integrity. This process provides uniform heat distribution and small temperature differentials, making it suitable for herbal beverages that are sensitive to color and flavor changes, while helping to preserve their original sensory characteristics and functional components.
