PX 110 Disc stack centrifuge0 pages
High-capacity disc stack centrifuge for fats and oils refining
PX 110
The Alfa Laval range of centrifuges for the vegetable and animal oils refining industries is continuously modernized to incorporate the advantages of current developments in mater-ials, mechanical design and fluid dynamics. The PX 110 is the largest machine in this range of centrifuges.
Applications
Continuous degumming, neutralizing, dewaxing, and washing of fatty oils, such as vegetable oils, lard, tallow and fish oil.
Performance
The table below shows nominal capacities. Actual throughputs
vary according to the type of oil and fat to be treated.
Degumming, neutralization, washing 54,000 kg/h
Dewaxing 25,000 kg/h
Standard design
The machine consists of a frame with a base that contains a horizontal drive shaft, worm gear, lubricating oil bath, and hollow vertical bowl spindle. The bowl is fixed on top of the spindle, inside the space formed by the upper part of the frame, the solids collecting cover, and the frame hood. The hood carries the liquid discharge system.
All parts in contact with the process liquid are made of stain-less steel.
The bowl is of the solids ejecting disc type, with an automatic hydraulic operating system for “shooting”. The standard elec-tric motor is suitable for variable frequency drive.
Design features
The PX 110 is based on a unique, semi-hermetic design
concept. The hermetic, bottom-fed inlet ensures a gentle,
non-destructive acceleration of the feedstock up to full bowl speed. The flow area for the feedstock has been increased to minimize inlet pressure drop.
The outlets on the heavy and light phases are open, reducing the pressure drop across the separator. The feed-pressure requirement of the machine is therefore low.
The outlets are equipped with stationary paring devices for removal of the different phases. The paring disc on the light phase is fixed, while the paring tubes on the heavy phase are adjustable.
PX 110 complete with motorBy adjusting a positioner on the heavy phase outlet, the operator can reduce or enlarge the paring diameter of the paring tubes. This patented innovation makes it possible to adjust the position of the separation interface during opera-tion, facilitating optimal separation.
With the working environment in mind, the PX 110 is designed to operate at low noise levels. This is achieved by means of a rubber-damped bearing assembly, jacketed frame and an outer bowl design engineered for low wind noise.
Standard equipment
Each PX 110 comes complete with control unit, electric motor, inlet and outlet connections, auxiliary equipment, a spare parts kit and a set of tools.
