Alfa Laval AFPX 617 Separator
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. Thecentrifuge 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 separatio duties.
Product Description
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.
| 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 them 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.
Basic equipment
Concentrator or purifier parts, inlet and outlet devices, revolution counter, set of erosion-protective parts, illuminated sight glass box for light phase outlet, vibration switch, vibration-isolating base plate, flange motor, set of tools and standard set of spares.
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.
