The role and application of dry valve aseptic cold filling technology

The emergence of dry valve aseptic cold filling technology solves the problem of environmental pollution

Aseptic cold filling technology is the world's advanced filling technology. At present, most of the sterilization methods adopted by the world's aseptic cold filling technology are wet sterilization. A big problem in wet sterilization is that the sterilization water is cleaning. When the bottle is bottled, it will inevitably be polluted, and the water after sterilization is seriously polluted by the sterilizing medium. It is necessary to take measures to drain and handle it, which will have a serious impact on the environment. The emergence of dry valve aseptic cold filling technology has solved this problem well.

The wet aseptic technique is to wash the sterile medium with sterilizing water after sterilizing the bottle. In this process, the sterilizing water is naturally contaminated by the sterile medium. When contaminated water enters the water treatment system, it will pollute the environment, and KHS's dry valve technology does not need water at all: introduce hydrogen peroxide (H2O2) into the bottle, disinfect the lid, and evaporate hydrogen peroxide (H2O2) with hot air. Then dry the container with hot air. Dry valve technology is suitable for all types of containers, regardless of bottle shape or size. It can be disinfected even in locations that are difficult to reach like the handles of plastic skimmers. The small, closed part of the container is sterilized using the patented micro-isolation technology (micro-sterilization chamber).

Dry valve aseptic cold filling technology can save 50% cost

The sterilization medium used in wet sterilization is mostly polyacrylic acid PAA, which is relatively expensive, thus limiting the application of aseptic cold filling technology to a certain extent. The sterilization medium used in the dry valve technology is H2O2. The H2O2 sterilization medium is much cheaper than the traditional sterilization medium polyacrylic acid PAA, and the traditional sterilization production line consumes a lot of water and costs a lot of money. KHS has compared these two technologies in Europe. Compared to traditional wet aseptic technology, dry valve technology can save 50% of the cost.

Application of PET bottled beverage medium temperature filling technology in high speed production line

Since the birth of PET bottled beverage medium temperature filling technology in China, the filling production line using this technology has matured in just a few years and has formed a certain market scale. This technology is based on the temperature limit of ordinary PET bottles. Through the matching filling production line, filling environment, and subsequent processes, the product preservation is achieved without adding any preservatives.

The bottle sterilizing of the low- and medium-speed production line adopts the method of the chain conveyor belt with a long pouring time. This method has a large area and needs to be supplemented with artificial righting bottles, which is not suitable for the automation and high speed of the production line. In order to meet the requirements of high-speed production line, Xinmeixing borrowed and adopted the inverted bottle sterilization chain mode of high-temperature filling production line. At the same time, in order to meet the sterilization time requirement of the bottle cap, the spray cooler is designed as a spray sterilizer to compensate for the defects of insufficient sterilizing time of the bottle, so that the product can be fully sterilized before cooling.
