Plastic bottle cap bactericidal device and bactericidal method thereof

Abstract

The invention discloses a plastic bottle cap sterilization device with good sterilization effect, high production capacity and high space utilization rate and a sterilization method thereof, while the invention is applicable to a filling production line of drinks and drugs. The device mainly comprises a soaking sterilization room, a sterile water spray room and a sterile air spray room; a plastic bottle cap enters an Archimedes spiral bottle cap channel of the soaking sterilization room for soaking sterilization; then the plastic bottle cap enters a ramping-up bottle cap channel for lifting and overturning; after that, the bottle cap enters a linear bottle cap channel and serially enters the sterile water spray room and the sterile air spray room for sequentially receiving the spray of sterile water and the spray of sterile air. A nozzle in the soaking sterilization room provides power for moving forward, ramping-up and overturning of the bottle cap; nozzles of the sterile water spray room and the sterile air spray room carry out the flushing and the spray-sweeping of residual sterilizing liquid on the bottle cap and provide the power for moving forward. The detection of the bottle cap sterilized shows that the sterilization effect reaches 6D (log6) and the residue of disinfectant liquid is not more than 0.5ppm. The two items are both meet the sterilization requirements for the bottle cap by aseptic cold filling.

Description

technical field [0001] The invention relates to an industrial sterilization device, in particular to a device for sterilizing plastic bottle caps in an aseptic cold-filling beverage line or medicine filling production line. The invention also provides a sterilization method for the device. Background technique [0002] Aseptic cold filling of beverages (juice, tea, milk beverages, coffee beverages, etc.) refers to: aseptic materials (juice, tea, milk beverages, coffee beverages, etc.) In the packaging (plastic bottle, plastic cap). Therefore, the sterilization effect of plastic bottles and plastic caps is one of the important parameters of the aseptic cold filling production line. Similarly, on the pharmaceutical production line that uses plastic bottles to fill tablets or fill liquids, it is also necessary to sterilize plastic bottles and plastic caps, and the standards are higher. [0003] The traditional plastic bottle cap sterilization method is as follows: a linear bo...

AI Technical Summary

Problems solved by technology

A number of sterilizing liquid spraying units composed of a single nozzle are used to spray and disinfect plastic bottle caps. Since the liquid sprayed by the nozzle is linear, such a sterilization method will have a sterilization dead angle, which cannot achieve the aseptic cold filling of beverages. Required bactericidal effect: the bactericidal effect reaches log6 and the residual disinfectant solution is ≤0.5ppm; it also cannot achieve the bactericidal effect required for drug filling

[0006] 2. Some bacteria on the surface of plastic bottle caps need a longer time (such as 30 seconds) of sterilizing solution to be killed

The traditional linear spraying type sterilization device needs to be made very long, and the equipment takes up a lot of space
