VO
Alfa Laval centrifuges for vegetable oil are continuously modernized to benefit from developments in materials, mechanical design and fluid dynamics. The VO range of low- and medium-sized separators are for continuous degumming, neutralizing, and washing.
VO separators are based on a simple, robust and well-proven, open design concept, and are easy to maintain. The design reduces the pressure drop across the separator and results in a low feed pressure requirement to the machine.
The bowls of the VO range are specifically designed for fatty oil separation. The geometry permits minimal pressure drop and high flow rates, and outlets are equipped with stationary paring devices for removal of the different phases. The paring device on the light phase is a fixed paring disc, while the paring device on the heavy phase is adjustable.
The diameter of the heavy phase paring device can easily be adjusted by changing the length of the paring tubes. This makes it possible to adjust the position of the separation interface in the disc stack, facilitating optimal separation.
With the working environment in mind, the VO separator range is designed to operate at low noise levels. This is achieved through a rubber-damped bearing assembly, and an outer bowl design engineered for low wind noise.
Cómo funciona
La fuerza centrífuga provoca la separación en la pila de discos, ya que obliga a las partículas más pesadas a dirigirse hacia la periferia del recipiente y descargarse automáticamente a través de los puertos, mientras que la fase ligera fluye hacia el centro del bowl.
La fase pesada se bombea fuera del separador a través de la salida de fase pesada situada en la parte superior. De manera similar, el aceite más ligero se bombea para su procesado posterior a través de una salida de fase ligera, situada también en la parte superior del separador.
