SKIMMING PROCEDURE
Best skimming results are achieved, when starting to skim immediately after milking. If milk
is cooled, warm it up to a temperature between 30 to 35 ºC. Milk cannot be skimmed with
temperature lower 30 °C. When the milk is properly warmed up, pour it in the container.
• Turn on speed controller box (look picture B ) with I / O main switch (E). Push switch in
position 1(start). Push motor switch (G) in position 1 (start). Wait 30 seconds until top bowl
reaches working speed. Working speed can be seen in digital display (look picture C). Cream
separator has a frequency inverter, which provides slow and soft motor start. This prevents
sliding of the top bowl on the motor.
• When the motor has reached its working speed (on digital display C shows 7500) turn
closing cork to open position. The end of the closing cork is turned to the cut in the contai-
ner and flow is opened. The skimmed milk leaves the bowl through the four holes in the top
bowl and flow out on the lower milk outlet. The cream leaves the bowl through the cream
adjusting screw and flows out on the upper cream outlet.
• After you have finished skimming procedure pour approximately 10 l of skimmed milk
back into milk container. This will clean the rest of cream in the top bowl. When all procedu-
res are finished, simply push toggle motor switcher (G) in position ˝O˝.
• When you push motor switch (G) in position ˝O˝, the motor starts supervising his own
stopping. After 130 seconds the motor stops. At that time digital display shows 0 (look pictu-
re C). Now you can turn off the main switch (E)
When milk is coming out of the outlets holder holes the closing cork must be closed imme-
diately while the motor is still running. When all the milk has left the bowl, the motor must
be switched off. Check what is wrong.
• You have opened the closing cork before the motor has reached working speed.
• Top bowl nut was not fixed enough.
• Rubber washer is placed badly, or it is destroyed.
After you have finished skimming, pour approximately 12 l of skimmed milk back into
milk container. This will clean the rest of cream in the top bowl. After all procedures
are finished, simply turn OFF the device and wait until motor stops.
CLOSING CORK MUST ALWAYS BE CLOSED BEFORE TURNING OFF THE DEVICE!
AFTER FINISHING THE PROCESS, CLEAN AND DRY THE DEVICE CAREFULLY!
WHEN THE MACHINE STARTS TO WORK, THE TOP BOWL AND THE DISCS MUST
ALWAYS BE COMPLETELY DRY.
ALWAYS CHECK, WHETHER THE RUBBER WASHER IS DAMAGED OR TOO MUCH
EXTENDED. IN SUCH CASES PLEASE REPLACE IT WITH A NEW ONE.
