AFPX617 - High capacity solids-ejecting centrifuge0 pages

High capacity solids-ejecting centrifuge for the animal and fish processing industries
AFPX 617
Alfa Laval AFPX separator centrifuges were specially designed
for extremely demanding separation jobs. Key features of the
AFPX 617 centrifuge are its ability to handle high flow rates,
high solids content and high-temperature processing. These
functions make it the ideal choice to handle the tough conditions
encountered in the animal and fish processing industries.
In addition, the AFPX 617 centrifuge combines a high Gforce,
high sludge capabilities and automated operation. The
centrifuge bowl is made of Super Duplex stainless steel, which
makes it possible to combine extremely high erosion resistance
with a very high bowl speed for demanding separation
duties.
Applications
The AFPX 617 is designed for intermittent discharge of solids,
while separating two intermixed and mutually insoluble liquid
phases of different densities. In different optimized executions
it is used for a large number of duties, from handling separation
of fish press liquid, stick water and extracts, and on the
other hand purification of fish oil and liver oil, animals fats, peel
oil and similar products.
Performance
The actual throughputs depend on variables such as the
amount and type of solids, the temperature, viscosity and
degree of separation required. The following figures indicate
the rate of performance, although no guarantees are given.
Alfa Laval representatives will be pleased to provide you with
further information.
AFPX 617 complete with motor
Separation - fish press water 28.000–40.000 l/h (120–180 US gpm)
Purification - fish oil 18.000–23.000 l/h (80–100 US gpm)
Purification - animal fat 7.000–10.000 l/h (30–45 US gpm)
Standard design
The machine consists of a frame that has a horizontal drive
shaft with clutch and brake, worm gear, lubricating oil bath
and vertical bowl spindle in the lower part. The bowl is
mounted on top of the spindle, inside the space formed by
the upper part of the frame, the ring solids cover, the collecting
cover, and the frame hood. The feed and liquid discharge
system, including the paring disc pump for the heavy phase,
also rests on this structure. All parts in contact with the
process liquid are made of stainless steel. The bowl is of the
solids-ejecting disc type with a hydraulic operating system for
“shooting” (for automatic or manual operation). The electric
motor is of the variable frequency drive type or of controlledtorque
type.
Optional extras
Starter equipment, frequency converter, discharge control
panel, standard set of fittings, set of CIP valves and fittings,
and serviceability package for online viewing of separator
status.
