Automatic COP/SOP means there is no need for manual cleaning and disinfection of the inside of the machine, which reduces or completely eliminates the risk of man- made pollution and extends the con- tinuous operation cycle of the equip- ment. The PET solution extends shelf from three to seven days to 21 days. Equipment selection Although capital costs of tradi- tional ultra-clean equipment are small, the safety and production costs are poor. Aseptic equipment can meet the requirements of low-temperature fresh milk to extend the safe shelf life of low-temperature fresh milk in terms of safety, but initial investment cost is high, but the production costs have no advantages. Tech-Long ultra-clean preform dry sterilisation blowing-filling-capping monobloc is available for a moderate capital cost. It competes by offering advantages in terms of safety and equipment production costs. It can greatly improve the shelf life of low- temperature fresh milk products while reducing energy consumption in pro- duction. It is the first choice for major dairy companies to produce long-shelf low-temperature fresh milk products. www.tech-long.com Tech-Long ultra-clean preform dry sterilisation blowing-filling-capping monobloc sterilisation of full-size bottles. Using the heat of the bottle blower to heat and evaporate the hydrogen peroxide in the preform removes residues with- out additional heating and air drying. Dry bottle sterilisation has to adapt to bottle thickness. If it is too thin, it will be thermally deformed. Preform sterilisation does not need to consider heat deformation. The sterilisation effi- ciency of the bottle can be stabilised to 3~5 log, according to demand. As a gas, hydrogen peroxide eliminates dead corners. The sterilisation pro- cess has a broad spectrum, with effi- ciency stable to more than 3 log. The blowing-filling-capping mode controls bottle pollution from the source. The ready-to-use mode prevents second- ary pollution during bottle transfer. The whole unit is equipped with 100-level purification. The main filling and capping machine have a liquid seal. The flowmeter, electrical com- ponents, valves and other parts that are not easy to clean and are likely to cause secondary pollution are located New equipment combination, new process route Tech-Long ultra-clean preform dry sterilisation blowing-filling-capping monobloc process flow: Preforms are first processed through the closed unscrambler. The neatly ordered preforms first pass through the bottle mouth UV sterilisation sec- tion before entering the bottle blowing machine. Ion dust removal eliminates debris particles in the preform. The pre- forms are sterilised with hydrogen perox- ide, using the heat of the heating mecha- nism of the bottle blowing machine for drying, and then blown and moulded by aseptic high-pressure air. They are then sent for filling and capping. Reduce equipment energy consumption, improve product safety, and extend shelf life Dry preform sterilisation is rela- tively fixed, at 2~6ml/min, offering considerable savings compared with November 7-9, 2021, Dubai At the Krones booth A1-34 German Technology Innovative hotrunner optiRun
