Sterilization of materials is the most critical step in the production process of glass bottle capping machines. Due to the material's heat resistance, only chemical reagents can be used for sterilization. To ensure that the glass bottles and lids are effectively sterilized, chemical reagents cannot be allowed to affect the materials. The following measures have been taken for aseptic filling: The original number of bottles in the bottle is no more than 5 cf/bottle; the conveying bottle uses sterile air and has an air conveyor belt; the interior of the bottle is sterilized with peracetic acid disinfectant (PAA), which can achieve a high bactericidal effect (up to 7 log). At the same time, disinfectant is sterilized on the outside of the glass bottle; the disinfectant has an automatic recovery and concentration measurement system to ensure that the concentration of the disinfectant is stable; the residual disinfectant in the bottle is rinsed with sterile water and then dried with sterile air. To ensure that the residual disinfectant does not affect the material; the bottle cap is generally sterilized by a disinfectant, and the sterilization effect can be well ensured by controlling the soaking time.
Because the bottle does not shrink after cold filling, there will be - part of the air between the material and the bottle cap, and the oxygen in it will slowly oxidize during the storage process, resulting in deterioration of the beverage. Therefore, the full glass bottle capping machine equipment will add a nitrogen (or other inert gas) replacement system, blowing the top of the air to ensure that the material is not oxidized.
For the maintenance of a sterile space environment, separation measures between cleanrooms are generally used. The main body capping machine is designed as a D100 class air purification room, and there are 10,000 class purification rooms (some aseptic filling equipment is not required). The filtration system of the purification room ensures the cleanliness of the air in the filling environment so that the materials will not Secondary pollution by microorganisms suspended in the air.
For the neutral beverage can not be used for hot filling process for production, due to the use of inverted bottle cap sterilization, high acid drinks can also inhibit the growth of microorganisms, while the neutral beverage can not guarantee product safety, product defect rate is high . If a hot tea filling process is used to produce neutral tea beverages, preservatives must be added. For the full glass bottle capping machine, since the aseptic condition is compared from the two process flow charts, the biggest difference is that the beverage heating time is different. It is known that the longer the heat treatment time, the greater the influence on the quality and taste of the beverage. All glass bottle capping machine adopts UHT ultra-high temperature instant sterilization, the heat treatment time of the material does not exceed 30 seconds, and can completely guarantee the sterilization effect under high temperature conditions, while the sterilization method used in hot filling makes the material stay at high temperature for a long time. Next, it seriously affects the taste, color, and heat-sensitive nutrients (such as vitamins) of the product.
In addition, from the point of view of the production line configuration, when the capping machine fails to stop the elbow, the materials processed by the hot filling method have - part of the backflow will prolong the heating time, which will seriously affect the quality of the entire batch of products, and the full glass bottle screw cap The machine will not have this phenomenon, and the material has been reduced to room temperature after it has been sterilized instantaneously. Placing it in a sterile tank will not affect its quality.
Comparison of bottles used. From the above filling process, it can be seen that the two filling methods require different bottles. The hot-filling process requires the bottle to withstand high temperatures of 85°C to 92°C and does not change. This requires increasing the crystallinity of the material and limiting the generation of induced stress during blowing. Its use of the bottle has the following characteristics: the bottle wall thickness, a clear bottle wall ribs to prevent thermal shrinkage; requires a crystal bottle, etc., greatly limiting the bottle design freedom. Glass bottle capping machines can use lightweight bottles (up to 60 °C heat resistance) and standard caps, which greatly reduce the cost of bottles and caps, but also the freedom to choose the design of bottle type. Under the filling, the process is adaptable, and the types of products that can be produced are very wide, including neutral tea beverages, milk beverages, and various other beverages. The adjustment of the pretreatment equipment can change the product type.
