CREAM SEPARATOR. Danish type. The milk is fedthrough the pipe A, and passed down the conical center through tubes and into the separating panat the bottom. The creambeing of less gravity thanthe milk separates underthe high speed of the pan,and is carried up along thecone and discharged over thetop of the revolving pan tothe spout at the left denser milk gathers atthe outside of the pan andrises through the openingsin the annular groove andis scooped up by the dis-charge pipe B.

The simple routineof the process of refrigeration by the circulation of ammonia. It con-sists of three principalparts : A, an evapora-tor, or, as sometimescalled, a congealer, inwhich the volatile liquidis vaporized. B, a com-bined suction and com-pressor pump, whichsucks or, properly speak-ing, aspirates the gasor vapor from the evaporator as fast as formed. C, a liquefier or, ascommonly called, condenser, into which the gas is discharged by thecompressor pump, and under the combined action of the pump pressureand cold condenser the vapor is here reconverted into
