Overview of sterilization process for beverage caps

At present, the bactericidal water used for the sterilizing of beverage bottle caps basically uses stable hydrogen peroxide, peracetic acid and ozone water, and most of them are the most environmentally friendly and stable hydrogen peroxide.
There are unstable elements in the bactericidal water and they decompose spontaneously. Bactericidal water sterilization is the use of this decomposition process (oxidation process) to oxidize the surface of the microorganisms, so as to achieve the purpose of sterilization.
Common materials with strong oxidizing properties are: stable hydrogen peroxide (containing ionic components), peracetic acid, ozone water, and chlorine water. The greater the concentration of bactericidal water, the shorter the required sterilization time. For 2000 PPM peracetic acid at 65°C, sterilization can be achieved through 20 seconds to 40 seconds. (The stable hydrogen peroxide (containing ionic components) has a broad-spectrum bactericidal effect and can kill hand and foot Pathogenic bacteria, Escherichia coli, Candida albicans, Salmonella, Staphylococcus aureus, Pseudomonas aeruginosa, Pseudomonas aeruginosa, Enterococcus faecalis, Streptococcus pneumoniae, Microemulsion, Micrococcus spores, Alcaligenes Over 200 bacteriological, biological, virological and toxicological tests, including Streptococcus, Corynebacterium, and Lactobacillus, have been tested and validated (copies of these test reports are available upon request). The sterilization time is short, the sterilization effect is good, and it is widely used for the sterilization of bottles and caps of fruit and vegetable juice beverages.The method of using the sterilizing water to sterilize the beverage bottle cap mainly includes the jet flush type and the immersion type.
1. Sprinkler type is the use of multiple groups of nozzles to spray sterilizing water in multiple directions on the lid of the beverage bottle to sterilize the surface of the beverage bottle cap. The time of receiving the injection of the beverage bottle cap should ensure that the microorganisms can be completely killed. The specific method is as follows: the cover of the beverage bottle after the lid is covered into the bottle cover track in a consistent direction, and multiple sets of spray heads are arranged on the upper and lower sides of the track. Each set of spray heads can spray the sterilizing water to the drink bottle cover from different angles, and the sprayed sterilizing water Both the cap is sterilized and the cap is pushed along the track.
When peracetic acid and ozone are used as bactericidal water, the beverage bottle cap after the sterilizing water is sprayed needs to be washed with sterile water in order to remove residual peracetic acid and ozone on the cap. Keep the residue below the relevant standard; rinse with sterile water and blow dry the cap with sterile air.
When using stable hydrogen peroxide (containing ionic components) as bactericidal water, the product after decomposition of hydrogen peroxide is water and oxygen, and there is no harmful residual material, (because the Norfolk fungicide is through the stability Hydrogen peroxide and colloidal silver ions kill microorganisms, bacteria, fungi, and viruses. The residues are hydrogen peroxide that is not used up, and it is decomposed into water and oxygen, and silver ions. Even at the outlet of the bottle cap sterilization machine In the case where the cover machine is very close, stable hydrogen peroxide is also completely decomposable (the product itself is completely soluble in water). Therefore, after the beverage bottle cap has been sterilized with stable hydrogen peroxide, it is no longer necessary to rinse with sterile water. Sterile air blow dry. At the same time, the stable hydrogen peroxide bactericide is sterilized by oxidation. Therefore, a major problem in the prevention of viruses, bacteria, fungi, microorganisms and other unknown diseases is solved: the resistance of microorganisms. With stable hydrogen peroxide, there is no need to worry about resistance, and you can use a bactericide for a long time.
Due to the linearity of the spray water, sterile water spray sterilization can be used for the sterilization of mineral water bottle caps, and can also be used for the sterilization of bottle caps during the hot filling of tea beverages and fruit juice drinks. Hot filling adopts full bottle filling, filling and capping, inverting the bottle to heat the beverage bottle cap, and performing internal sterilization treatment.
Due to silver ions as a stabilizer. Normal hydrogen peroxide is unstable, which means that it can be slowly decomposed in water and oxygen. To solve this problem, a small amount of silver was added as a stabilizing agent to the stable hydrogen peroxide sterilizing agent. This stabilizer can prevent the slow decomposition of hydrogen peroxide, stable hydrogen peroxide can be used at 0-95 degrees Celsius, stored at a constant temperature of 54 degrees Celsius for 14 days, the effective content is reduced by only 0.42% to 0.64% (The Academy of Military Sciences Detection) Stability Hydrogen peroxide can therefore be stored for use.
2. The immersion type is to fully immerse the beverage bottle cap in the sterilizing water so that all the inner and outer surfaces of the cap are sterilized by the sterilizing water. Since the stable hydrogen peroxide has a strong oxidizing and sterilizing function, the soaking time of the beverage bottle cap is within 10 to 20 seconds. Can meet the time requirements for complete sterilization of caps. One method is: the bottle caps with the same direction are fixed on the bottle racks, and the bottle racks are connected to the chains. The movement of the chain drives the bottle racks into the sterilization tank with bactericidal water and completely soaks the bottles in the sterilizing water. The soaking time of the beverage bottle cap can meet the time requirement of full cap sterilization in 10-20 seconds. As with the spray sterilizing method, the sterilized water-impregnated bottle cap also needs to be sprayed with sterile water and sprayed with sterile air, so that the beverage bottle cap is both dry and sterile.
