Did you know that a high-concentration ozone water machine can sterilize bottle caps?

  High concentration ozone water machineThere are unstable elements in it, and they will differentiate by themselves. Ozone water sterilization is to use this differentiation process (oxidation process) to oxidize the microorganisms on the surface of the object to achieve the purpose of sterilization.


Common substances with strong oxidizing properties are: peracetic acid, ozone water and chlorine water. The instantaneous sterilization properties of ozone are better than chlorine. At present, the sterile water for the sterilization of beverage bottle caps basically uses peracetic acid and ozone water, most of which are perozed water. Ozone water sterilization has no residue. The greater the concentration of ozone in the water, the shorter the required sterilization time. For 10-30mg/L ozone water in the water, sterilization can be carried out from 30 seconds to 60 seconds, so that the bottle cap can meet the requirements of commercial sterility. Because ozone water has a short sterilization time and good sterilization effect, it is widely used in the sterilization of bottles and caps of fruit and vegetable juice beverages. The main ways to sterilize beverage bottle caps with a high-concentration ozone water machine are spray type and immersion type.


1. The spray type is to use multiple sets of nozzles to sterilize the surface of the bottle cap by spraying high-concentration ozone water in multiple directions of the bottle cap. When the bottle cap receives the eruption, it should ensure that the microorganisms can be completely killed. The specific method is: enter the bottle cap track together through the bottle cap after the cap is sorted. There are multiple sets of nozzles above and below the track. Each set of nozzles can spray high-concentration ozone water machine on the bottle cap from different angles. The high-concentration ozone water machine not only sterilizes the bottle cap, but also pushes the cap to move along the track. When using ozone water as sterilized water, because the products of ozone hydration are water and oxygen, there is no harmful residue In theory, there is no need to reprocess the bottle cap, but in the actual production process, because the exit of the bottle cap sterilizer is very close to the capping machine, the residual ozone cannot be completely differentiated. Therefore, after the bottle cap is sterilized by ozone water It also needs to be rinsed with sterile water and dried with sterile air.


2. The immersion type is to thoroughly soak the beverage bottle cap in sterilized water, so that all the inside and outside of the bottle cap are sterilized by a high-concentration ozone water machine. The time of soaking should meet the requirements of complete sterilization of the cap. One way is to fix the bottle cap with the same direction on the bottle cap holder, and the bottle cap holder is connected to the chain. The movement of the chain drives the bottle cap holder into the sterilization tank equipped with the high-concentration ozone water machine and makes the cap thorough Soak in sterilized water, and the time of soaking should meet the requirements of complete sterilization. The same as the spray sterilization method, the bottle caps immersed in the high-concentration ozone water machine need to be sprayed with sterile water and sterile air to make the caps dry and sterile. Therefore, this sterilization process is generally applied to aseptic cold filling of fruit juice beverages.
