Glass bottle cap unscrewing machine production process
The sterilization of material, is eco-friendly tube bottle cap unscrewing machine is the most crucial step in the production process. As a result of the material is not heat resistant, can only use chemical reagent for sterilization, to ensure the glass bottles and LIDS get effective sterilization, and can't keep the chemicals affect the material, aseptic filling adopted the following measures: first blowing bottle original colony count no more than 5 cf/bottle; Transmission using aseptic air bottle, want to have the air conveyor belt; The bottle inside use disinfectant peracetic acid class ( PAA) Bactericidal effect of sterilization, can achieve very high ( Top 7 log) ； For the eco-friendly tube bottle external disinfectant sterilization; Disinfectants have automatic recycle and concentration measurement system, guarantee the stability of disinfectant concentration; With sterile water in the bottle of residual disinfectant is rinsed clean, sterile air blow dry, reoccupy guaranteed residual disinfectant will not affect the material; Cap generally use disinfectant soaking type sterilization, by controlling the soak time can be very good to ensure the sterilization effect.
due to shrinkage after cold filling bottles won't, there will be - between such material and bottle caps Which part of the air, the oxygen will slow oxidation material during storage, resulting in beverage metamorphism. So, the entire bottle cap unscrewing machine equipment will add a set of nitrogen ( Or other inert gas) System, the replacement will be at the top of the air blown away, keep the material from oxidation.
keep sterile space environment, commonly used to purify the segregation measures. The screw cap machine design level for the D100 between air purification, and between grade purification (outside Some aseptic filling equipment do not need) By filling between purification filtering system to ensure that environmental cleanliness of the air inside, make the material will not be suspended microbial secondary pollution in the air.
for neutral beverage can't use hot filling process for production, due to the way of using inverted bottle cap for sterilization, high acid drinks can also inhibit microbial growth, and neutral beverage is unable to ensure product safety, product defective rate is very high. If use hot filling process neutral tea drinks, you must add preservatives. For the whole bottle cap unscrewing machine, because it is in sterile conditions from both comparison process flow diagram, the biggest difference is that different time for heating the beverage. As is known to all, heat treatment, the longer the greater the effect on beverage quality and taste. All eco-friendly tube bottle cap unscrewing machine adopts UHT instantaneous ultra high temperature sterilization, to material heat treatment time is not more than 30 seconds, and under the condition of high temperature can ensure the sterilization effect, and thermal sterilization methods used by filling material for a long time in high temperature condition, the serious influence product taste, colour and lustre and heat-sensitive nutrients ( Such as vitamin) Content.
in addition, from the production line configuration, when screw cap machine downtime, and USES the hot filling process of material - Part would be to extend the time of heat, this will seriously affect the whole batch of the quality of the products, and the bottle cap unscrewing machine won't have this phenomenon occurs, the material is down to room temperature after instantaneous sterilization, aseptic tank will not affect its quality.
used bottles of comparison. Can be seen from the above filling process, two kinds of filling way is different to the requirement of bottle. Hot bottle filling technique requirement to withstand 85 ℃ ~ 92 ℃ high temperature and constant, which requires the increase the crystallinity of materials, at the same time in the bottle blowing to limit the generation of induced stress. The use of bottle has the following features: bottle wall thickness, there is a clear bottle wall frame to prevent thermal contraction; Require a crystal bottle, etc, which greatly limits the bottle type design degrees of freedom. bottle cap unscrewing machine can use lightweight bottle ( The highest heat temperature 60 ℃) And the standard cover, which greatly reduce the cost of the bottle and the lid, also can free choice bottle type design. Under filling, its process adaptability is strong, can produce has a very wide range of product types, including neutral tea drinks, milk beverage, and other drinks, just adjust pre-treatment equipment can change the product type.
