The machine is mainly used in the beverage filling operations. The three functions of bottle washing, filling and sealing are composed in one body of the machine. The whole process is automatic. The machine of isotonic filling methods(D type)is used in filling aerated beverage in bottles made of polyester and plastic. The handle of the machine can be freely and conveniently turned to adjust the machine to fill various types of bottles. The filling operation is faster and more stable because the new isotonic pressure filling operation of the new type is adopted. There the output and benefit of the machine is higher than the machines of the same specifications. The advanced OMRON programmed controller(PLC)is adopted to control the machine to run automatically while a transducer is used in the bottle-entering chains to adjust speeds and coordinated with the transducer of the main machine to make the operations of moving bottle forward steadily and reliably. It is convenient to operate with higher automation because every part of the machine is inspected to run with photo electricity. The machine is an idea-preferred equipment for beverage producers.
