A preform disinfection method and bottle making equipment

Abstract

The invention discloses a preform sterilization method and bottle-making equipment. The sterilization method for sterilizing a plastic preform used for molding in a device for producing aseptic bottles includes at least the following steps: (1) by The ultrasonic atomizer turns the disinfectant into a disinfectant mist, and sprays the disinfectant mist on the preform to adhere a substantially uniform thin layer of the disinfectant on at least the inner surface of the preform to be disinfected; (2) The preform thus treated is radiantly heated to raise at least the inner surface of the preform to a first temperature greater than or equal to the activation temperature of the sterilizing solution to sterilize at least the inner surface of the preform. The present invention provides a method for sterilizing a preform and a bottle making device. After ultrasonically atomizing the disinfectant, it is sprayed directly to make it evenly adhere to the surface of the preform without heating the disinfectant to the steam temperature, the energy consumption is relatively low, and the energy consumption is relatively low. It also avoids the loss caused by making the disinfectant into the disinfectant vapor.

Description

technical field [0001] The invention relates to the technical field of bottle blowing machines, in particular to a preform disinfection method and bottle making equipment. Background technique [0002] As the beverage industry has higher and higher requirements for food safety, more and more attention has been paid to the pollution of beverage packaging. Especially for dairy beverages, the pollution of packaging containers will directly affect the quality of the product. At present, most of the industry uses disinfectant to sterilize the utensils and then wash them, but there is a large consumption of disinfectant and sterile water, and there are even residual problems, which are likely to cause secondary pollution. [0003] At present, there is a method and a device for blowing a bottle after spraying a sterilizing solution on the preform, reheating and sterilizing, and finally blowing the bottle. In this device, it is condensed on the surface of the preform by spraying h...

AI Technical Summary

Problems solved by technology

With this method, it is not only necessary to keep the preform at a low initial temperature (lower than the condensation temperature of the sterilant vapor), but also to preheat the liquid sterilant to make the sterilant vapor, which consumes a lot of energy and requires equipment preparation. The cost is relatively high; at the same time, because the temperature of the disinfectant steam is higher than the activation temperature of the disinfectant, the disinfectant is partially decomposed in the steam state, which affects its disinfection effect
