This water column in the discharge pipe seals the vacuum and at the same time permits the water from the spray and the condensation water to escape auto- matically. The cistern in which the water column terminates should be of sufficient size to hold about one-third more water than the ca- pacity of the entire length of the discharge pipe calls for and should have a large overflow into the sewer. When the pan is in operation and a uniform vacuum is maintained, the level of the water column remains constant and the excess water from the condenser over- flows from the cistern into the Fig. 22. The wet-vacuum spray condenser Courtesy ot Arthur Harris & Co. The Wet-Vacuum Spray Condenser consists of a huge hol- low cylinder of brass or iron, usually, but not necessarily, horizontal. The horizontal spray condensers are usually equipped with a perforated spray pipe, placed lengthwise in the cylinder. This spray pipe should run close to the top side of the cylinder, so as to give the spray that escapes from the holes on the upper side of the spray pipe a chance to strike the top of the horizontal cylinder with force and to become atomized. The spray pipe connects at the end nearest the pan with the pipe supplying the cooling water. When the pan is in operation, a shower of cold water issues forth from the per- forations of the spray pipe as the result of the reduced pressure in pan and condenser. The force with which the water escapes these perforations is further augmented by the fact that in most cases the water supply tank is located higher than the condenser. The hot vapors arising from the boiling milk in the pan are drawn over into the condenser, where they c
