Milk, cheese and butter, a practical handbook on their properties and the processes of their production . Butter Extractor was the first to claim notice. It consistsof a separator, within the drum of which a circular wheel-frame ofbars is placed, which can be carried by a lever into a position whereits bars can strike into the rapidly moving cream, and made torevolve by its action upon them. The globules are thus broken,and pass off in place of the cream, with some buttermilk. The BUTTER-MAKING. 319 next step was taken Ij)- Dr de Laval, \\ho attached to the frameof his separator a churn driven from the spindle, and receiving thecream as it issued from the outlet and passed over a cooler. For thisit was properly claimed that the reduction of temperature beforechurning was an advance on the other machine, which either churnedit at the separating temperature, or separated at one much too machine, howe\er, was withdrawn for perfecting, as it is reported,and is not now in the market. The most recent invention is theAmerican Accumulator, which is attached to the Laval separator,. Fig. 188.—Butter Accumulator (Part Section). but is of separate manufacture. As shown in Fig. 188 it consists of acollar, which is secured to the neck of the drum. The cream escapingfrom the drum flies into the angle a, and when this is filled risesthrough the aperture d to the terraces c c, filling the angle of each inturn, and then flying over its upper edge into the angle of the the top terrace it passes through the tube d into the circularchamber, where the butter separates in fine granules from the butter-milk, and reaching the inner opening of the tube /, is dischargedinto the collecting dish /i, while the buttermilk passes through thetube g into the same. This device appears to have come to stay,as the Americans would say. There is doubtless room for improve-ment, but the principle will be developed, and make the production offirst-class and long-keeping sweet-c
