Abstract

A homogenizing apparatus comprises a casing having an internal cylindrical surface defining a bore having an open end. A portion of the surface is threaded and the casing defines an inlet portion terminating in an annular chamber along the threaded portion substantially centered between the ends thereof. A rotatable closing plug in the open bore end has a cylindrical threaded portion meshing with the threaded portion of the internal cylindrical surface and longitudinally extending grooves along the cylindrical threaded portion of the plug. The threads of the threaded portions and the grooves define homogenizing passages and the annular chamber surrounds the threaded portion of the plug and communicates with the homogenizing passages whereby a liquid or pasty product delivered under pressure into the inlet port is divided into two equal streams flowing from the centered annular chamber through the homogenizing passages in opposite directions. An outlet conduit receives the streams of homogenized product. Rotation of the plug controls the variation of the section of the homogenizing passages.

Claims9

Dependent claims

An apparatus for homogenizing a liquid or pasty product, which comprises

(a) a casing having an internal cylindrical surface defining a first bore having an open end,
(1) a portion of the internal cylindrical surface being threaded and
(2) the casing defining an inlet port terminating in an annular chamber substantially centered between the ends of the threaded portion,
(b) a rotatable closing plug in the open bore end, the plug having
(1) a cylindrical threaded portion meshing with the threaded portion of the internal cylindrical surface the threads of the internal cylindrical surface of the casing being truncated in transverse section in a progressively variable fashion by a second bore of the casing having an axis offset from the geometric axis of the first bore, and
(2) longitudinally extending grooves along the cylindrical threaded portion of the plug, the threads of the threaded portions and the grooves defining homogenizing passages, and the annular chamber surrounding the threaded portion of the plug and communicating with the homogenizing passages whereby a liquid or pasty product delivered under pressure into the inlet port is divided into two equal streams flowing from the centered annular chamber through the homogenizing passages in opposite directions and the variation of the section of the homogenizing passages is controlled by the rotation of the plug in relation to the casing, and
(c) an outlet conduit receiving the streams of homogenized liquid or pasty product.
