Spray sterilization kettles are suitable for aluminum cans due to their precise pressure control and uniform heat distribution.
The system atomizes hot water through nozzles, creating a fine spray that evenly covers the can surfaces, ensuring thorough sterilization without dead angles. The key lies in its sophisticated pressure control system, which dynamically adjusts the internal pressure of the kettle to match the pressure changes inside the aluminum cans during heating, sterilization, and cooling phases. This counter-pressure function is critical as it prevents the relatively malleable aluminum cans from deforming, denting, or bursting under stress. Additionally, the indirect heating and cooling method separates the process water from the cooling water, safeguarding the cans from potential re-contamination and better preserving the juice quality.
