LPT 311: Milk and Milk Products Technology (1+1)

ASSEMBLING OF CREAM SEPARATOR

• Check the cleanliness of separator parts which is normally washed in Luke warm water followed by detergent washing, hot water sterilization and dried. 
• Insert the milk distributor through the central axis fixed in the base of the cream separator and fix by proper locking. Position the rubber ring in the base at the proper slot.
• First, place the bottom disc with button structure on both the sides. Then place other discs one after another over the bottom disc so that the holes in the discs are in line.
• Finally place the top disc with cream screw. Bowel shell is fixed promptly positioning the cream outlet and the base to sit over the rubber ring and lock.
• The bowel nut is fastened and tightened. Thus, the properly positioned rubber ring and bowel nut prevents leakage of milk at the base and top. Fix the skim milk spout and cream spout.
• Regulating chamber with float and supply can with faucet are finally fixed. Keep the faucet in the closed position so that milk is not wasted while filling the supply can with milk. After assembling the unit, clean the separator with clean hot water.
• Fill the supply can and allow the separator to rotate by operating the handle at high speed or by switching on the motor attached to the separator. Now open the faucet and regulate the flow so that milk does not spills over.

Calculations

Skimming efficiency of cream separator = Quantity of fat in cream X 100 / Quantity of fat in milk

Fat loss in skim milk = Quantity of fat in skim milk X 10 / Quantity of fat in milk
