Abstract

254,725. Stassano, H. July 1, 1925, [Convention date]. Concentric straight-tube apparatus.-Liquids, such as milk or beer, are pasteurized or sterilized by passing them in a layer endless e.g. annular, in transverse section and about one mm. in thickness between heated metal walls. The path is at least ten thousand times longer than the thickness. The rate of flow of the liquid may be about 2 metres per second. The walls are preferably made of metal, such as copper, having a good conductivity and a low thermal capacity, and may be maintained at a temperature of 70-75‹ C. for pasteurization and of 120-135‹ C. for sterilization. Milk may be completely pasteurized at a temperature of 70-75‹ C. in about 8-10 seconds by flowing it along a path 8-10 mm. thick and at least 10 m. long at a rate of 2 m. per second. Copper tubes are preferred to aluminium. In the apparatus described, the liquid flows from pipe 10 through the annular spaces 6 formed between a series of coaxial tubes 3, 5 supported by members 4 in a container 1 filled with liquid heated by a steam &c. coil 2. Passages 9 connect the spaces 6 at alternate ends, the liquid flowing out through pipe 11 after traversing successively all the spaces 6. The liquid in container 1 is circulated by a pump through a pipe 13 and unions 12 to the interiors of tubes 5, to keep their temperature uniform.
