Preform disinfection method and bottle making equipment

Abstract

The invention discloses a preform disinfection method and bottle making equipment, and particularly relates to a disinfection method for performing disinfection on a plastic preform which is used formolding in sterile bottle producing equipment. The method at least comprises the following steps of (1) preparing disinfectant into disinfectant mist by using an ultrasonic atomizer, and spraying thedisinfectant mist to the preform, attaching a substantially uniform thin disinfectant layer to at least the inner surface of the to-be-disinfected preform; and (2) carrying out radiation heating on the preform treated in this way, enabling at least the inner surface of the preform to be heated to a first temperature, wherein the first temperature is greater than or equal to the activation temperature of the disinfectant so as to at least carry out disinfection on the inner surface of the preform. According to the preform disinfection method and the bottle making equipment, the disinfectant isultrasonically atomized and directly sprayed to be evenly attached to the surface of the preform, disinfectant does not need to be heated to the steam temperature, energy consumption is relatively low, and meanwhile loss caused by making disinfectant into disinfectant steam is avoided.

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...

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
