The system adopts five steps of hot water spray sterilization and gradual cooling and cooling. The equipment configuration has automatic chlorine pump, can be adjusted according to the dosage of water supply. The hot water is generated by a steam heating device, and the water flows into the water tank of the machine frame. If the hot water temperature can not reach the set temperature, the heating device to the appropriate heating. If the hot water temperature exceeds the set temperature (the cooling water has been heated by the heat inside the bottle), the circulating pump is sent to the cooling tower outside the workshop (which is supplied by the user) to be recycled after cooling.
