Processing of raw produce for the food processing industry inevitablygenerates waste and sometimes spillage. Such is the case with potatoprocessors, Swancote Foods of Telford whose products are employed forcold products for leading manufacturers and retailers.
Principal area for concern is at the end of the preparation line where potatoes are peeled and diced. Here, waste can spill into the void where themotor driving a centrifugal pump for transferring the diced potato tothe next stage of production is located.
Until recently this motor was a standard, finned, mild steel AC machine which, although brushed clean frequently – a time consuming operation - could not be washed down because of the potential risk of shorting the electrics and/orencouraging rust.
To overcome the potential health risks presented by this situation, Swancote has replaced this motor with a stainless steel unit from Marlin Stainless, a division of AEG.
This new Marlin stainless motor offers numerous benefits in addition to stainless steel’s inherent rust resistance. These include an IP66 ratingthat permits high-pressure hose wash downs, which is much quicker thanbrushing, and a smooth body with round terminal box that have no awkward angles or crevices to trap food and breed germs. Further, there is no motor plate to catch food because the motor information is etchedinto the body.
In addition to all the above advantages provided relating to hygiene, the Marlin motor, being a standard IEC metric unit, simply dropped into place. No modifications were necessary to accommodate it.
Marlin motors are offered in power ratings from 0.18 to 7.5 kW in metric frame sizes up to 132 as TEFC machines. Smaller units (up to 0.75 kW) are also available from 63 frame size as TENVmachines.
Helping to extend the range of applications for theMarlin motors are compatible stainless steel gearboxes. These worm gearboxes, which have hollow shafts with life lubricated gears, are available with centre distances of 31, 42 and 61mm with ratios from 5:1 to75:1. Torques range from 0.9Nm to 208Nm.
