How does the Centritherm® evaporator work?

The Centritherm® evaporator is a single-effect, centrifugal evaporator that operates under vacuum and uses steam as the heating medium. The heating surface is the underside of hollow, rotating cones.

The product to be concentrated enters the evaporator through a feed tube and injection nozzles (one for each cone) distribute the product to the heating surface. Centrifugal force instantaneously spreads the product over the entire heating surface in an extremely thin layer (approximately 0.1 mm). The product passes across the heating surface in less than one second.

The concentrated product collects at the outer edge of the cones and then exits the evaporator through the stationary paring tube.

Product vapour removed from the extract rises through the center of the cone stack and enters an exhaust pipe that transfers it to an external condenser.

Steam is supplied to the evaporator through a hollow spindle to the steam chamber inside each hollow cone.

As the steam condenses, the condensate is immediately projected to the upper wall of the hollow steam chamber. The condensate exits the steam chamber through a channel and is removed from the evaporator via a paring tube.

The Centritherm is easy to operate, service-friendly and hygienic (includes CIP function).
