Alfa Laval Foodec decanter centrifuges combine unparalleled efficiency with exceptional hygiene, in a design that minimizes oxidation in delicate food and beverage products. They provide extremely efficient liquid extraction that leaves a particularly dry waste product. The Foodec design actually boosts solids handling capacity by as much as 25% compared with all other designs currently available – at no additional cost.

Foodec solutions are designed for separation duties in industries with a particular focus on hygiene standards and on avoiding the effects of oxygen pick-up. The unique Alfa Laval Foodec design features an advanced sealing system that virtually eliminates any intake of air. This makes these units ideal for use in breweries and in the manufacture of a wide range of beverages and viscous foods, including  wine, fruit juice, casein and lactose, coffee and tea, tomatoes and soy protein isolate.

The advanced drive system paves the way to much lower power consumption than any other current designs, and the innovative 2Touch control system reduces operating costs and gives even better control over the separation process. Together, this results in lower separation costs as well as boosting both the quality and value of the end product.

How it works

Foodec - How it works

Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor. The product is fed into the bowl through a stationary inlet tube, and is smoothly accelerated by an inlet rotor. Centrifugal forces cause any solids within the feed to accumulate on the wall of the bowl.

A conveyor rotates in the same direction as the bowl, but at a different speed. This gradually moves the sedimented solids towards the conical end. The Alfa Laval Foodec design enables the hydraulic pressure inside the bowl to improve scrolling through a narrow opening. Only the driest fraction of the solids leaves the bowl through the discharge openings into the casing. Separation takes place along the entire length of the cylindrical part of the bowl, and the clarified liquid exits by flowing over adjustable plate dams into the casing.

Alfa Laval Foodec decanter centrifuges all feature a new generation of paring disc design, a high-capacity conveyor and the 2Touch control system that reduces operating costs and provides an exceptional degree of control over the separation process. This controller is fitted with a graphic user interface and extensive communication options.
