For as at Techne, aseptic is a synonym of safety and of the capacity to supply 100% of your products in sterile containers.

Aseptic standard processes include the sterilization of bottles before filling (internal and external), which implies using chemicals such as Oxonia (peroxyacetic acid / hydrogen peroxide) and rinsing with water after the. The process can be tricky with bottles that have specific shapes with dead areas, thus it being difficult to guarantee there is no residual chemical after the treatment that could alter the final product’s properties- such as the taste of a specific product.

As a solution for this issue, many companies chose a technology that directly feeds the filling unit with sterile bottles, so there is no need to rinse with water the insides of the bottles.

At Techne, the concept of Aseptic Blowing has been developed since 1992 and is used on numerous dairy and pharmaceutical lines worldwide. It consists of a sophisticated system that filters the air used to form the bottles and sterilizes the air piping circuit with steam, thus eliminating the use of any chemical agent.

The result is a sealed and sterile bottle which comes out from the extrusion blow-moulding machine, before it is stored in silos or sent directly to the sterile chamber for filling.
