Abstract
178,636. Testrup, N., and Techno- Chemical Laboratories, Ltd. Feb. 16, 1921. Film evaporators.-A film or layer of moist peat, lignite, &c. is formed upon the periphery of a rotating drying-drum by pressing the material against the heated drying surface by means of a roller of smaller size moving peripherally at a speed so much lower that the film adheres to the drying surface in a practically unbroken layer. Peat, for example, containing between 70 per cent and 90 per cent of water may be fed into the V-shaped trough between two cylinders b, c, the larger b of which revolves at between two and three times the speed of the smaller feed roller c. The material adheres to the surface of the drying cylinder b, which may be roughened to facilitate the adhesion, until, when dried, it is removed by a scraper e and transferred to a conveyer f. The vapour evolved by the material may be heated by compression, as described in Specifications 149,055 and 150,068, and employed in heating the drying- drum.
