To quickly assess the difficulty of the text, read a short excerpt:
To obtain c low, cooling of the cream inside the drum should be avoided, and the cream exit large. Separators in which the adjustment of the thickness of cream is performed at the cream exit have a large c. It is more difficult to express by a definite formula the amount of fat in skim milk obtained by allowing milk to stand. Here we have not a definite space through which the globules of fat THEORY OF CREAM SEPARATIOX. 259 must pass, as in the cream separator, where the layer of milk is always... of constant thickness ; the space is determined by the depth of the layer of milk set. The formula _ s ir'' t ~ c may be transformed into t = — , where « is a constant. r' Taking the diameter of the largest globules as O'Ol mm. and the smallest as O'OOIG mm., we calculate that the smallest globules will take about fifty times as long to pass through a given space as the largest ; the author deduces from his experiments that the largest fat globules move at the rate of 15 mm. per hour. If we assume that the total weight of fat globules of any size, is equal to the total weight of fat globules of any other size, in an ordinary cream tube we may expect roughly the following figures : — In ') hours about 35 per cent, of total fat will be found in the cream.
