A unique technology for aseptic filling
Our aseptic filling machines are engineered to take the risk and complexity out of your operations. Designed for smooth, extended production runs between Clean-in-place (CIP) processes, they ensure top-tier food safety.
Ecolean packages arrive pre-formed, pre-sterilised, and hermetically sealed to customer site. This eliminates the risks associated with on-site sterilisation and the use of hazardous chemicals.

Ecoleans filling machines for aseptic solutions
Explore the benefits
Aseptic system
Ecolean delivers pre-formed, pre-sterilised and hermetically-sealed packages that are ready to fill. There is no need for package forming or package sterilisation on the customer's site. This offers customers a simple and cost-efficient operation with low risk and the highest standard of food safety.

High efficiency
Ecolean aseptic filling machines enable long production runs between CIP processes, that outperform most conventional packaging systems:
-
High acid products (PH <4.6) 96-hour production runs (such as for juice)
-
Low acid products (PH>4.6) 55-hour production runs (such as for milk or yoghurt)
No water consumption
Ecolean filling systems use no water during filling or ice water for cooling, which enables customers to use less fresh water in their operations. Water is only used during CIP and chamber cleaning.
Low labour intensity
-
No package forming or sterilisation is performed at the customer site.
-
Simple quality controls save time for the operator.
-
Less than 25 minutes/hour is needed to operate an Ecolean filling machine – including the Ecolean recommended quality controls.
Less chemicals
Ecolean's pre-formed and pre-sterilised packages ensure negligible hydrogen peroxide consumption during production.
This not only significantly reduces chemical costs during production, but also enhances safety for the machine operator as concentrated hydrogen peroxide is not handled during production. Only a 1% hydrogen peroxide spray is used inside the chamber, which minimises exposure to hazardous chemicals.
Less liquid food waste during production
The design of the Ecolean filling system and the limited number of quality controls needed, minimise the wastage of your liquid food product during the filling process. This helps to lower operating costs and food waste.
Low energy usage
Ecolean filling machines are designed with low-energy consumption in mind. During production, the Ecolean filling machine EL6 only uses 8.5 kW per hour.
Flexible system for switching between packaging formats
Ecolean filling machines offer operational flexibility and low downtime when switching packaging sizes. Switching to another packaging size only takes on average 15-20 minutes, depending on operator experience.
Ecolean filling machines also offer flexibility in terms of being able to fill several different packaging sizes. Ecolean® Air Aseptic 125 ml, 200 ml, 250 ml can be filled with the EL6 and EL4+ filling machines, and Ecolean® Air Aseptic 500 ml, 750 ml and 1,000 ml with the EL3+ filling machine.
Ready-to-fill packages
The pre-formed, pre-sterilised and ready-to-fill packages are supplied hermetically sealed by Ecolean plants. Before opening, filling and sealing in the filling machine, the outer surfaces of the packages are re-sterilised.
Optimise your operations
To reduce labour needs and downtime, Ecolean filling machines feature automatic roll-changes, material splicing, and an advanced monitoring system and operator interface. The CIP process is also fully automated along with external cleaning that occurs automatically in an integrated circulating cleaning system.
