Aseptic packaging treatment
Serac, Hall A5 – Stand 332 Serac confirms its expertise in container treatment based on dry processes with an industrial sterilisation solution using ebeam technology, capable of ensuring a 5 log bacteriological reduction on Bacillus Pumilus without leaving any chemical residue in the container and eliminating the consumption of chemical agents to decontaminate a bottle, BluStream is a technological breakthrough in the aseptic filling of plastic bottles, says Serac.
According to the company, BluStream is particularly interesting for manufacturers wishing to highlight production processes that respect both human beings and the environment as well as brands that follow natural trends and target sensitive consumers (babies, elderly people, people with allergies, etc.).
Unlike peracetic acid (PAA) and hydrogen peroxide (H2O2) treatments that rely on chemical principles, BluStream is based on a physical process. It uses an issuer which throws an electron beam over the container’s surface. Electrons quickly destroy micro-organisms by breaking their DNA chains. This enables BluStream to achieve a 5 log bacteriological reduction on Bacillus Pumilus with a 1.5l bottle in about 5s.
The BluStream process only depends on three critical easy to control parameters: voltage, current intensity and exposure time. BluStream treatment is also more economical in production because it requires no chemicals, no water, no compressed air, and a minimum increase in electrical consumption comparable to the H2O2 treatment, says Serac. The unit is more compact than PAA and H2O2 ones; the floor area is only 20m² for a rate up to 36,000bph. Bottles are treated on two successive carousels; the first one for the exterior treatment and the second one for the interior treatment of the bottle, continuously, at rates up to 36,000bph.
BluStream treatment is compatible with all kinds of plastics; HDPE, PET, PP, PS, whatever their weight or shape. All bottle sizes can also be treated, provided that the neck diameter is above or equal to 30 mm.
Treatment efficiency allows this method to be used for high-acid products (fruit juices) as well as for low-acid products (cow milk, soy milk, other vegetable milks and all nutritional products).
