Vacuum pan with mill< trap Courtesy of Arthur Harris & Co If the pipe through which the milk enters the pan is turned down and its end is carried to near the bottom of the pan, so as to avoid the formation of excessive milk spray, if the pan is operated carefully and if the milk is kept at a reasonably low level, there is very little danger of milk being carried over into the condenser in quantities sufficient to be of any consequence. Under these conditions the installa- tion of a special milk trap between the pan and the condenser for the purpose of collecting the escaping milk spray and carrying it back to the pan is, therefore, an unnecessary expense. If the pan is small in comparison to the amount of milk to be condensed, and if it is forced beyond its intended capacity so that the milk boils up high, there usually is considerable loss of milk, as indicated by the foaminess. and milky color of the exhaust of the vacuum pump. In such cases the mechanical loss of an average size batch may amount to several hundred pounds of milk. In order to not lose this milk, a milk-trap or catch-all may be installed between the pan and the condenser. The vapors loaded with the milk spray enter the trap near the top. The spray drops to the bot- tom of the trap, while the vapors are drawn over into the condenser, where they are condensed as usual. This trap may be constructed of sufficient size so as to serve as a reservoir to collect all the milk that is carried over, and at the conclusion of the process the con- tents of the trap are drawn from the bottom and are condensed with the next batch; or the bottom of the trap may be connected with the pan so that the milk thus carried over flows back into the pan auto- matically. In this case a small trap only is necessary. It should be under
