APPARATUS FOR DRYING MILK

The United States Consul at Gothenburg publishes the following translation of an article lately appearing in a Swedish newspaper:—Dr Martin Ekenberg's invention was exhibited to representatives of the press in the factory at Birger Jarlsgatan, owned by the company which will utilise the invention. By the assistance of the exsiccator, skimmed milk is transformed into a highly soluble powder, which, dissolved at a temperature of GOdog. to 70deg. C-. above zero in a proper quantity of water, gives a solution with the same taste, smell-, and other qualities as common milk. The flour, or powder, can be easily transported and can be kept a long time without being spoiled. The invention is considered to be of great importance for utilising skimmed milk, which, can be kept sweet only a very short time and cannot be transported loir* distances, but still bas considerable alimentary value. The yearly output of skimmed milk from our dairies amounts to 600,000,000 liters (158,520,000 gallons), according to the statistics of the Department of Agriculture. This milk may yield a quantity of milk fleur of the isame market value as the total export of butter. The price of a large exsiccator, which evaporates 2,000 liters (528 gallons) of skimmed milk in ten hours —such a one has since last December been nearly every day in operation with good results —will cost 4000 to 5000 kronor (<£2ls to JJ3OO). At the present time such apparatus are being built for ten dairies, and inquiries about the apparatus are nearly every day received from interested persons in Sweden and foreign countries, among whom Americans are prominent. It is further reported that the evaporation takes place at such a temperature that a person V it bout burning bis hand can put the same on the apparatus while it is working, and that the manufacture of the finest kind of milk flour is done in vacuum,, so that the air cannot act unfavourably upon tho milk under the process.
