The machine is used to fill mineral water and purified water in bottles of polyster and plastics. The machine is conveniently turned to adjust the machine to fill various types of bottles. The filling operation is faster and more stable due to the micro-negative pressure filling operation of the new type is adopted. The output and benefit of the machine is higher than the machines of the same specifications. The advanced OMRON programmed controller(PLC) is adapted to control the machine runs automatically, air conveyor system is adopted in bottle entry section and belt conveyor system is adopted in bottle exit section, which can adjust speed and coordinated with transducer of the main machine to make the output of moving bottle forward steadily and reliably. It is convenient to operate with higher automation due to every parts of the machine which is inspected to run with photo electrical detector. The machine is ideal-preferred equipment for beverage makers.
