Alfa Laval VO 5
The Alfa Laval range of centrifuges for the vegetable oil refining industry is continuously modernized to take advantage of developments in materials, mechanical design and fluid dynamics. The VO 5 is a small-sized separator in this range of centrifuges.
Applications
Continuous degumming, neutralizing and washing of fatty oils, such as various vegetable oils, lard, tallow and fish oil.
Standard design
The VO 5 is a top fed self-cleaning separator. The machine consists of a frame with a lubricating oil bath, a horizontal belt driving device, and a vertical bowl spindle. The bowl is fixed on top of the spindle and covered by the frame hood. All process wetted parts are made of stainless steel. The bowl is of the solids ejecting disc type, with a hydraulic operating system for sludge discharging. The separator is driven by a standard electrical motor with friction clutch. Gaskets and sealings are made of nitrile rubber.
Design features
The VO 5 is based on a simple, robust and well-proven, open design concept. Furthermore, the VO 5 is easy to maintain. The design reduces the pressure drop across the separator and results in a low feed pressure requirement to the machine. The bowl of the VO 5 is specifically designed for fatty oil separation. Its geometry permits minimal pressure drop and high flow rates. The 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 5 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.
Standard equipment
Each VO 5 comes complete with starter and control unit, electric motor, inlet and outlet connections and auxiliary equipment.
