BOTTLING / FILLING PETplanet Insider Vol. 21 No. 09/20 www.petpla.net 44 PET aseptic filling technology in big health era With the diversification of consumer’s demand about healthy drinks, beverages are also rapidly updated all the way, and it takes individual needs and more difficult technical chal- lenges to aspect packaging technology. Since the first generation of aseptic filling technology, Newamstar’s aseptic filling technology has been continu- ously upgraded and has released sev- enth generations of aseptic filling tech- nology to the market. It has achieved a leap in capacity of production line, expands of the application field contin- ually, and kept pace of the sterilisation technology for aseptic filling beverages with the times, and has been updated. In addition, a lot of improvement has been made in energy saving and con- sumption reduction, and environmen- tal protection of the equipment: The basic energy consumption required for aseptic startup, the early aseptic filling production lines required the coordina- tion of multiple chemicals to reach the aseptic environment, and the produc- tion process also required a large number of chem- icals to maintain the stability of the aseptic envi- ronment continu- ously. One method of dry asep- tic technology introduced by Newamstar is to use atom- ised hydrogen peroxide instead of peracetic acid for sterili- sation, which greatly saves the amount of chemicals used and solves the problem of residual disinfec- tion solution. The other method is to use the electron beam physical sterilisation method, which replaces the use of chemicals to realise no chemical residues, and to be more environmental-friendly. Newamstar’s dry aseptic technology has sustainable technology models and concepts. Newamstar’s PET aseptic filling technology can be used for different packaging forms and different pack- aging specifications, while enriching product diversity. In order to meet customers’ requirements for quickly switching product specifications, Newamstar relies on combining the blowing-filling-spinning machine tech- nology, a variety of materials com- patible filling technology, and multi- specification PET bottle rotary blowing technology. In the blowing unit, the quick change function of the mould can be easily realised. The fastest mould replacement time for a single cavity can be con- trolled at 75 seconds. Operators only need to adjust the star wheel when changing for different bottle types. In the filling unit, when changing different bottles, operators only need to adjust the star wheel, which is fast and con- venient. It has also developed filling clips that are compatible with different bottle mouths, which is suitable for the online conversion of multiple bottle mouth products in the future. In the capping unit, personalised products can be applied in the capping systems, and can match the corresponding cap torque according to different specifica- tions of the bottle cap. At the moment Newamstar said, that it is further build- ing a flexible production unit with the function of switching various bottle types and various products online, achieving the spectacular situation of “one production line at a hand, all in the hand”. www.en.newamstar.com
