Abstract
An injection molding bottle sterilization method comprises the following steps: 1, inverting an injection molding bottle, atomizing a glutaraldehyde solution, sprinkling the atomized glutaraldehyde solution on the inner wall and the outer wall of the injection molding bottle to sterilize, and guaranteeing the action time of the glutaraldehyde solution in a range of 5-12s; 2, flushing the inner wall of the bottle body with 80-90DEG C distilled water from the mouth of the injection molding bottle for 2s to clean the bottle body, wherein the pressure of the distilled water is 0.5-1atm; 3, blowing aseptic hot air with the temperature of 80-90DEG C to the mouth of the injection molding bottle for 8-10s; and 4, irradiating the injection molding bottle with ultraviolet lights with the wavelength of 255nm at a radiant quantity of 400-600W.s/m<2> for 2h. The inverted injection molding bottle is adopted, the glutaraldehyde solution is used to kill harmful bacteria on the inner wall of the plastic bottle, and the plastic bottle is flushed and dried and undergoes ultraviolet light irradiation sterilization, so composite sterilization effectively reduces the adhesion amount of the harmful bacteria on the plastic bottle.
Description
Technical field
The present invention relates to the method for disinfection of a kind of injection moulding bottle。
Background technology
Along with plastic bottle is global universal, requiring more and more higher to asepticization of vegetable oil production equipment and packaging material, the sterilization technology round the bottle of charge of oil, lid is constantly improving and upgrading。Plastic bottle is as the pith of packaging material, it is generally adopted centralized production, sends the mode of each production line, pollute possible owing to there are some in transport and storage, therefore its bactericidal effect directly affects the quality of product, becomes an extremely important ring in production。The sanitary standard of state food containers demand is total plate count less than 100cfu/cm2, coliform, gold Portugal, Salmonella must not detect containing。If the plastic bottle sterilization of packaging edible oil and fat is not thorough, causing oils and fats quality variation in sales process, produce strange taste, long term consumer eats this type of oils and fats, can cause uncomfortable。
Existing plastic bottle sterilization mode Comparison of effect on sterilization is poor, it is easy to breed bacteria
Summary of the invention
In order to overcome the deficiency of existing plastic bottle sterilization mode Comparison of effect on sterilization difference, the present invention provides the method for disinfection of the injection moulding bottle that a kind of bactericidal effect is good。
This invention address that the technical scheme of its technical problem is: the method for disinfection of a kind of injection moulding bottle, step is as follows:
A, inversion injection moulding bottle, sterilize glutaraldehyde solution atomized spray on injection moulding bottle inside and outside wall, and ensure that its action time is 5～12 seconds；
B, alignment injection moulding bottleneck, with the distilled water flushing bottle inwall of 80～90 DEG C, clean 2 seconds, and the pressure of described distilled water is 0.5～1 atmospheric pressure；
C, brushing heated sterile air to the bottleneck of injection moulding bottle, its temperature is 80-90 DEG C, and action time is 8～10 seconds；
D, the ultraviolet radiation injection moulding bottle adopting wavelength to be 255nm, and ensure that amount of radiation is 400～600Ws/m2, irradiate 2 hours。
Further, the concentration of described glutaraldehyde solution is 0.5%。
Further, the fogdrop diameter after the atomization of described glutaraldehyde solution is 1～5um。
The beneficial effects of the present invention is: adopt and be inverted injection moulding bottle, use glutaraldehyde solution to carry out the harmful bacteria killing on plastic bottle inner wall, and be rinsed drying, ultraviolet radiation sterilizes, and composite bactericidal effectively reduces the adhesion amount of harmful bacteria on plastic bottle。
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail。
A kind of method for disinfection of injection moulding bottle, step is as follows:
A, inversion injection moulding bottle, sterilize glutaraldehyde solution atomized spray on injection moulding bottle inside and outside wall, and ensure that its action time is 12 seconds；
B, alignment injection moulding bottleneck, with the distilled water flushing bottle inwall of 90 DEG C, clean 2 seconds, and the pressure of described distilled water is 1 atmospheric pressure；
C, brushing heated sterile air to the bottleneck of injection moulding bottle, its temperature is 90 DEG C, and action time is 10 seconds；
D, the ultraviolet radiation injection moulding bottle adopting wavelength to be 255nm, and ensure that amount of radiation is 600Ws/m2, irradiate 2 hours。
The concentration of described glutaraldehyde solution is 0.5%。
Fogdrop diameter after the atomization of described glutaraldehyde solution is 1～5um。
The beneficial effects of the present invention is: adopt and be inverted injection moulding bottle, use glutaraldehyde solution to carry out the harmful bacteria killing on plastic bottle inner wall, and be rinsed drying, ultraviolet radiation sterilizes, and composite bactericidal effectively reduces the adhesion amount of harmful bacteria on plastic bottle。Through inspection, adopt after this method for disinfection harmful bacteria at adhesion amount at about 0 ~ 1cfu/cm2。
