Show ppNf COTTON DISK BEST STRAINER FOR MILK Farm Journal Correspondent Tells of Its Value. The most efficient milk strainer, we learn from G. Malcolm Trout, Is the dry cotton filter disk. The old wire gauge strainer Is no longer In favor with milk inspectors; and some of the cloths used as strainers are little if any better than the wire. Mr. Trout finds that cheesecloth doubled lets sediment through; that muslin is little lit-tle better than cheesecloth; that flannel, flan-nel, best of the cloths used, is not so efficient as the various cotton disks. There Is a difference, of course, In cotton disks. Some will filter more rapidly and more efficiently than others. oth-ers. The temptation is to hurry up a slow one by jarring. Mr. Trout found, In. his Michigan tests, that jarring jar-ring reduced elliciency; It seemed to i make small holes in the disks and let ' sediment through that had previously 1 collected. To hurry things up, A. C. Dahlberg suggests having the foot of the strain-! strain-! er as large as possible, so that an extra large disk can be used. He points out that milk goes through the '. disk vertically with very little hori-j hori-j zontal movement, and for that reason I the capacity is directly related to J the area of the holes In the metal supporting the cotton disk. Some of i the strainer manufacturers, he states, I have redesigned their strainers to in-! in-! crease capacity. Farm Journal. |
