Aseptic Filling

Growth market for sensitive products: KHS provides numerous innovations for system solutions

Dortmund, Germany

  • Further developments provide greater efficiency and flexibility
  • Bottlers benefit from improved product safety
  • KHS offers extensive portfolio for various requirements in aseptic filling

It is often a combination of small things that have a big impact, as is the case when filling sensitive beverages into PET and HDPE bottles. Here, with a whole range of innovations for its system solutions KHS provides greater efficiency, more flexibility, increased ease of operation and optimum product safety.

New ring gap filling valve for pulp and fibers

If the portfolio requires it, beverages with pulp and fibers can be processed by the new ring gap filling valve without any loss of performance. Products with fibers 15–20 millimeters long and a high pulp content can even be filled without the machine becoming blocked or clogged. As opposed to the usual filling valves with a gas lock, on the new valves the valve cone is placed directly at the discharge so that nothing sprays or drips. What’s more, the filling jet is so homogenous and streamlined that a lot less foam forms in the bottle.

Longer maintenance intervals

Whereas in the past maintenance was required at relatively short intervals for microbiological reasons, with each session lasting five to eight hours, maintenance intervals have now been lengthened so that machines only need to be serviced once or twice a year. Thanks to improved hygiene, increasing experience in the operation of machines and modern materials such as PTFE (polytetrafluorethylene or Teflon), KHS has been able to reduce its safety buffer down to a reasonable level. Now four times longer, these intervals follow on from one another and include all tests previously performed during maintenance. This gives beverage producers much higher machine availability. Operators also profit from cost savings for maintenance and overhauls of up to 20% within five years.

Aseptic filling technology from KHS is complemented by an extensive portfolio of proven process engineering machines. “We provide systems and solutions from a single source,” Härtel emphasizes. “These range from the blending of components in the syrup room through deaeration and aseptic flash pasteurization just before filling to chunk dosing in a dual-flow process.” The Dortmund company thus provides the full bandwidth of technologies and services needed to make the increasingly popular beverages in the sensitive product segment – from acceptance of the raw material concentrate through design of the bottles and their components to filling and packaging of the product.
