Washing

The operator should carefully follow the steps outlined in the Operator's Manual. Because the washing water is released into the bowl at 10 times the volume of the normal milk flow, the sediment is washed off with considerable force.

After the motor is switched off and the bowl speed falls to around 7,000 rpm, the bowl ring contracts, allowing the water and sediment to escape through the washing vents. Then the operator should switch the power on again so that the water will flow through the area exposed by the contracted bowl ring. Baffles on the collectors assist in thorough washing of all surfaces. See I1lust. 8.

Illust. 8--Cross-section of washing action with bowl turning at .7,000 rpm or less. The bowl ring is contracted and the washing slots are open. The bowl is washed inside and out.

Sterilizing

After washing, the operator should steri­lize the bowl and collectors, using eight quarts of hot water at at least 1800 F, as outlined in the Operator's Manual.

He should pas s about one -third of the hot water through the machine with the bowl turning at full speed. He should put the balance of the water through after the speed has been reduced and the bowl ring has contracted. In this way, both the inside and outside of the bowl are sterilized along with the collectors.

After the water stops flowing from the collectors, he should turn on the motor again and run the separator for two or three minutes. The heat from sterilization and the high speed rotation will thoroughly dry all the parts.
