Laminarflow DecAx (Food)

Germ- free air in the meat industry

Extends the shelf life of food. A special technology combines the demands of the meat industry with those of state-of-the-art cleanroom technology: Ortners Laminarflow DecAx is a complex laminar flow system with an integrated sterilization device specifically designed to prevent microbiological recontamination.

Air filtration and surface disinfection- two- in- one system: DecAx is a cleanroom system specially adapted for the processing and primary packaging sector. It has the function of air filtration and surface disinfection of the equipment interiors, based on a low-turbulence displacement flow.

Another advantage is that the DecAx ensures only short interruptions to production- thanks to the microbiological purity combined with the rapid drying of the machines and the processing rooms by the sorption technology.

 A lying cuboid, which hangs from the ceiling and becomes slightly wider from the bottom up. On the wider front side at the very top are four smaller grids lined up next to each other. On the surface itself is a depression in the form of fan blades. A few inches above the bottom edge, a blue stripe runs all the way around. On the wider front, this blue stripe says "FlowLine" on the left and "ortner cleanrooms unlimited" next to it. Narrow strips are attached to the bottom edge of the wider front and the wider back. The bottom of the box consists of a fine grid divided into two equal square panels.
 On the lower side, there is a conveyor belt with three sausage sticks lying side by side lengthwise. This conveyor belt leads to the back into a box. Above the conveyor belt, an elongated box, which can be seen from below, is attached to the ceiling. On the lower side of this box is a dark fine grid.
The production process itself is accompanied and protected by a guided clean air curtain
 On the right of the picture is a man wearing white protective clothing. Over this he wears a blue apron, blue protective gloves, a red protective mask and a red protective hood. His right hand rests on a plate on which a screen is mounted. In the background, three rows of plastic packaging are lined up on an assembly line. Inside these plastic packages are sliced sheets of sausage. Above the assembly line, hanging from the ceiling, runs a narrow box with a fine grid attached to its underside, separated by several panels. In the man's background, at the end of the room, is a cart, with ten shelves. In six of these shelves lie sausage sticks.
The system safety as well as the decontamination of the HEPA filters in the system, is ensured via UVc disinfection.
 There are three rows of plastic packaging on an assembly line. Inside these plastic packages are sliced sheets of sausage. Approximately in the middle of the conveyor belt there is a beveled plate on which a white conveyor belt is mounted. On it lie cut portioned sausage leaves. Above the conveyor belt, hanging from the ceiling, runs a narrow box, on the underside of which is attached a fine grid, separated by several plates.
The DecAx system draws in the air in the room and reintroduces it, sterilized and particle-free, directly above the respective work area

Conserves Resources and Last Longer

The surface decontamination inside the units and the effective treatment of the filter cells mean that a service life of five to seven years can be achieved for HEPA filter media in microbiologically contaminated areas.

Hurdle Technology

The 2- stage design of the system is referred to as "hurdle technology". The DecAx product line meets the strict requirements in terms of product safety and germ reduction in the processing of meat, delicatessen and sausage products.
