POWDERED MILK
A Remarkable Invention ia Credited to a Swedish Chemist. Milk that can be carried about in a snuff box or a tabaooo pouch, and that with the addition of a little water Ckh-' not be distinguished from the article which is freshly yielded from the cow, is one of the latest romances of science. This wonderful article is the invention of Dr. M. Ekenberg, a Swedish chemist, who is now a resident of London, and who demonstrated his process of drying milk recently. The process can cnly be described as “drying" milk, for that is what it is in its simplest form. The water which the milk contains is extracted from it and the solid parts which remain duced to a fine powder. All that is required to restore the powder to the condition of pure natural milk is toe add a quantity of water equivalent to that which has been extracted in the process of solidification. The essential part of Dr. Eken berg’s machine is what so known as the exsiccator. This consists of a steel drum revolving in a vacuum, which is heated to the temperature of the human body. The milk is pumped into the machine at one end and partially solidified before it reaches the drum. The thick liquid is then car ried over the drum, and by the time it has reached the side furthest' I from the pump it is solid and ip scraped off the drum by fijxed- knives, In- the shape of long, curling ribbons. These rtbbpns breaks .info fragments as they Mlfe ftp r T\? cle plac « celve them, and they are afterward milled’to a fi^soWer. ?a ” Tie powder wilt keOp indefinitely in tins, and it will keep for several lays after the tin is opened. Afibther advantage of the process'-Is that while the drying kills all the harmful bac-, "dnia in milk, it does not destroy the enzymes or ferments which add so much to the fopd value of milk.
