The sterilizer machine is mainly used to sterilize the interspaces which can not be reached by high temperature materials in the mouths or capsules of bottles after the beverage like tea or juice has been hot filled and closed over. After the product being filled and closed over, the bottle shall be inverted 90o automatically and put flatware by the machine, and the inner of the bottle shall be sterilized through the high temperature of the materials and then bottle shall be put vertically and enter into the spray cooler. The machine runs steadily and reliably and does no harm to the bottle body while the transmission speed can be adjusted steplessly because the transmission chains are imported to install in the machine.
