Abstract

461,439. Dispersing gases in liquids. DISTILLERS CO., Ltd., and LOCKEY, J. Aug. 23, 1935, No. 23698. [Class 14 (i)] A device for dispersing a gas or vapour in a liquid, particularly for application to fermenters used in the manufacture of yeast on the aeration principle, consists of a perforated hollow body, shown as comprising a conical part D and a cylindrical neck part D<1>, which is mounted on a rotatable shaft C with its major part submerged in the liquid. Its upper end communicates with the air space above the tiquid level E. When the body is rotated rapidly, the liquid normally within the body is thrown out centrifugally through the perforations, and air is then induced into the body from the air space and subsequently forced out centrifugally into the liquid surrounding the body. The vat A containing the liquid has a jacket B, and is provided with baffles A<1> for arresting any rotational movement of the liquid. In a modification, the hollow body is in the form of several short perforated cones extending along the shaft C. The shaft is mounted in a frame held frictionally in the vat and acting as a baffle. The cones may be of graduated sizes. Specification 455,547 is referred to.
