The drink machine is mainly used in the beverage filling operations. The three functions of bottle wash, fill and seal are composed in one body of the machine. The whole process is automatic. The machine of isotonic filling methods is used in filling carbon containing beverage in bottles made of polyester and plastics. 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 machinery of the same specifications. The advanced 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 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 makers.
