MILK CONDENSING. 335 niniiiiig' tlio pumps, wliieli is a considerable saviiio^ (lurinjjj the j-ear hy way of fuel. The factory has two vucuum-paus, one of which is a 6-foot pan with two coils of pipe, and 2,000 quarts of milk per hour is the usual rate of condensing. Mr. Borden believes in doing the work rapidly, and says the sooner you can get the milk from the cow into a condensed form the better. There are two boilers of horse-power each for supplying steam to the pans, and the average pressure of steam in the pipes, at the pan, is 55 to 60 lbs. to the square inch. The evaporation goes on best in clear dry weather; in damp, foggy weather it takes a little longer to get the water out of the milk. About 10,000 quarts are being con- densed per day. " The milk as it is received goes into squ:ire- amount of sugar is calculated for the given quan- tity of milk, and then turned into a movable tank or well, where hot milk is poured upon it till it is thoroughly dissolved. The hot sugared milk is drawn up last into the pan, and mingles there with the milk that has been partially condensed. The sugared milk must be eliminated of more water than plain milk, since the addition of sugar partially liquefies the mass—a curious fact. Three pints of milk make 1 lb. of sugared con- densed milk. The best quality of white granu- lated sugar is used, in the proportion of l;^lbs. of sugar to the gallon of milk. " The milk remains in the vacuum-pan for about three hours, during which time about 75 per cent, of its bulk in water is eliminated, when it is di-awTi off into cans holding about 40 quarts Fig. 20O.— Condensing Factory at Brewster, like boxes or va<s, the receiving-room being 4 or 5 feet higher than the bath and heating-room. The bath-tubs are circular, aud have a coil of steam jiipe at the bottom; they are filled within 6 or 8 in
