Embodiment 1

[0037]A method to keep the capping heads of rotary PET products sterile. A nozzle for washing and disinfecting the capping heads is added around the capping heads on the production line, and a disinfectant is sprayed out of the nozzles to kill the hidden microorganisms inside the capping heads and maintain the capping heads throughout the process. The inner wall is sterile. The nozzle is a universal nozzle, and the shape of the sprayed disinfectant is fan-shaped; the universal nozzle is equipped with a nozzle ball, and the unilateral rotation angle of the nozzle ball is limited to 22.5°. The angle range between the center line of the nozzle and the center vertical line of the capping head is 20°, and the distance between the top of the nozzle and the lowest point of the capping head is 2-5cm. The running speed of the capping head on the production line is 30,000 bottles / h; the inner diameter of the capping head is 28mm; the pressure of the disinfectant injection is 3bar, and t...

Abstract

The invention relates to the technical field of sealing cover cleaning, and discloses a method for keeping a rotary sealing cover head of a PET product sterile. For solving the problem that the sanitation dead angle of the inner wall of a sealing cover head cannot be thoroughly eliminated in the prior art, a nozzle for washing and disinfecting the sealing cover head is additionally arranged around the sealing cover head on a production line, disinfectant is sprayed out of the nozzle, microorganisms hidden in the sealing cover head are killed, and the inner wall of the sealing cover head is kept sterile in the whole process. The method has the beneficial effects that on the basis of cleaning and disinfection of a conventional filling machine, the nozzle for washing and disinfecting the sealing cover head is additionally arranged, the microorganisms hidden in the sealing cover head can be effectively killed in the production process, and the inner wall of the sealing cover head can be kept in a sterile state in the whole process; according to the method, the needed transformation spare part price and the operation cost are both low, and the part transformation cost does not exceed 400 yuan; and the method can ensure that the disinfectant residue in the product meets a standard requirement.

Description

technical field [0001] The invention relates to the technical field of capping cleaning, in particular to a method for keeping a rotary PET product capping head sterile. Background technique [0002] In the production process of high-nutrition PET bottle beverages, it is necessary to ensure that the filling and sealing environment is sterile, and the capping head in the filling clean environment has many dead ends for cleaning and disinfection due to its complex structure, such as the bottle cap inside the capping head is pushed out. The surface of the rod and the inner wall of the hollow shaft that moves up and down. During the production period, due to problems such as capping and capping, some products are not capped. During the transfer process of the capping machine, the internal material liquid will splash out and pollute the capping head, and the slurry entering the capping head cannot be washed in time. Or incomplete rinsing and disinfection will lead to the growth ...
