3. Skim milk powder of known moisture content.
PROCEDURE:
1. Make sure of the composition of reconstituted skim to be prepared.
2. Calculate correctly the proportion of different ingredients to be used for the preparation of the specified quantity of reconstituted milk with pre determined composition
3. Weigh correctly the quantity of skim milk powder and keep it ready for reconstitution process.
4. Take the powder with the known volume of water through the funnel and pump into the multipurpose vat.
