Flame sterilization subjects sealed metal containers to intense thermal radiation and convection from gas flames to achieve rapid commercial sterility. Continuous rotation of the container creates forced internal agitation, enhancing heat transfer into the bulk liquid and preventing localized thermal degradation or scorching at the inner wall. Determining the required rotational speed is critical for balancing throughput, thermal safety, and product quality.
