Abstract
Abstract A device for liquid treatment of granulated products comprises a cylindrical housing accommodating a coaxially mounted shaft with stirrers, which shaft carries at least one cup, above which there is fixedly secured a guide with a central aperture, while the shaft is hollow within at least the section of one cup and is provided with radial holes for supplying the liquid.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
A device for liquid treatment of a granulated product comprising a cylindrical housing, a rotary shaft coaxial with the housing, an upstanding cup and a stirrer secured to said shaft so as to be rotatable therewith, a fixed guide adjacent the mouth of the cup, said guide having a central aperture through which granules are fed into the cup, the underside of the guide being contiguous with the inner face of the cup, and at least one hole in said shaft extending transversely thereof from a hollow part of the shaft to the interior of the cup, the arrangement being such that, when the shaft is rotated and jets of liquid are ejected from the hollow part of the shaft through said hole into the cup and granules are fed into the cup through said guide, the granules are first wetted by said jets, and, due to centrifugal force, liquid moves up the inner face of the cup and forms a film thereon and on the underside of said guide, and the granules are further wetted by moving through said film on their way out of the cup.
Claim 2
Independent Claim
188 words
A device for liquid treatment of a granulated product comprising a cylindrical housing, a rotary shaft coaxial with the housing, an upstanding cup and a stirrer secured to said shaft so as to be rotatable therewith, a fixed guide adjacent the mouth of the cup, said guide having a central aperture through which granules are fed into the cup, the underside of the guide being contiguous with the inner face of the cup, and at least one hole in said shaft extending transversely thereof from a hollow part of the shaft to the interior of the cup, the arrangement being such that, when the shaft is rotated and jets of liquid are ejected from the hollow part of the shaft through said hole into the cup and granules are fed into the cup through said guide, the granules are first wetted by said jets, and, due to centrifugal force, liquid moves up the inner face of the cup and forms a film thereon and on the underside of said guide, and the granules are further wetted by moving through said film on their way out of the cup.
Claim 3
Dependent Claim
49 words
A device as claimed in claim 1, in which the cup is of frusto-conical shape and is coaxial with the shaft and the guide is in the form of a funnel coaxial with the shaft and having an external inverted trough extending peripherally at the mouth of the funnel.
Claim 4
Dependent Claim
32 words
A device as claimed in claim 1, in which there is at least one additional cup with the latter having a guide and stirrer, the additional cups being spaced one below another.
Claim 5
Dependent Claim
84 words
A device as claimed in claim 3, in which said cups are contained in an upper portion of the housing, the housing having a lower portion into which granules can pass from the upper portion and formed in sections one below another, the sections being separated by partitions having openings leading successively from one section to the next section and then to a discharge throat in the lowermost section, and each section containing a rotary paddle for sweeping granules through said openings and throat.
Claim 6
Dependent Claim
18 words
A device as claimed in claim 4, in which said openings are cIrcumferrentially displaced relative to one another.
Claim 7
Dependent Claim
30 words
A device as claimed in claim 1, in which the inlet of granules into the cup is through a gate which is controlled by a centrifugal governor on the shaft.
Claim 8
Dependent Claim
32 words
A device as claimed in claim 3, in which an upper portion of the housing comprises a plurality of drums between opposed faces of which peripheral flanges on said guides are clamped.
