Abstract
2800. Krepper, E. Feb. 4. Stills.-The compartments in a columnar still are composed of shelves 13, ring walls 15, trap cups 16, disposed over orifices in the shelves ; and pipes 20 conveying liquid from shelf to shelf. The undersides of the rims of the trap cups 16 are provided with vanes 17, Fig. II, which direct the vapours entering from the compartment below in such a manner as to impart a swirling motion to the contents of the ring 15. The liquid enters the still through a spreader valve 7, and is preliminarily heated in the pipe 5 by means of the residual liquor, which passes away from the still through a jacketing- pipe 23. A heating-medium, such as steam, is admitted to the still by a pipe 9. The apparatus may be applied to the treatment of liquids containing alcohol.
