Abstract
Abstract An apparatus to distribute discrete particles and, while distribution is occurring means to coat the particles, uniformly with a liquid. The apparatus provides feeding the particles to a rotating plate which rotates at a speed such as to distribute the particles and to cause them to move outwardly to the edge of the plate from which they fall and a liquid distributing means comprising an annular skirt coaxial with and below the plate, the skirt receiving liquid internally thereof and rotating at a speed sufficient to expell the liquid outwardly from its lower edge towards the particles falling from the plate thereby coating these articles.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
Apparatus for coating discrete articles comprising: supply means having a downwardly directed delivery means for discharging a continuous feed of articles; a rotating plate beneath said supply means for receiving the articles, said plate rotating at a speed sufficient to force articles off the edge of the plate in an even peripheral distribution; and a rotating coating assembly located below said plate, the assembly having a downwardly flared rotating annular skirt and fluid feed means extending within the skirt, said fluid feed means having radially outwardly directed aperatures for applying fluid to the interior of the skirt, said skirt rotating at a rate sufficient for fluid to move down the skirt to its lower edge and be expelled outwardly therefrom to strike the articles falling from the rotating plate and about the periphery of the skirt, the lower edge of said annular skirt being in the form of a continuous curve varying in the axial direction of the skirt to form an axial zone of fluid through which the articles fall for coating.
Claim 2
Dependent Claim
173 words
Apparatus for coating discrete articles comprising: supply means having a downwardly directed delivery means for discharging a continuous feed of articles; a rotating plate beneath said supply means for receiving the articles, said plate rotating at a speed sufficient to force articles off the edge of the plate in an even peripheral distribution; and a rotating coating assembly located below said plate, the assembly having a downwardly flared rotating annular skirt and fluid feed means extending within the skirt, said fluid feed means having radially outwardly directed aperatures for applying fluid to the interior of the skirt, said skirt rotating at a rate sufficient for fluid to move down the skirt to its lower edge and be expelled outwardly therefrom to strike the articles falling from the rotating plate and about the periphery of the skirt, the lower edge of said annular skirt being in the form of a continuous curve varying in the axial direction of the skirt to form an axial zone of fluid through which the articles fall for coating.
Claim 3
Dependent Claim
26 words
Apparatus as claimed in claim 1 wherein the feed of the articles to the plate is provided from two diametrically opposed outlets from the supply means.
Claim 4
Dependent Claim
20 words
Apparatus as claimed in claim 1 wherein the plate is rotated on a shaft located centrally of the delivery means.
Claim 5
Dependent Claim
15 words
Apparatus as claimed in claim 3 wherein the shaft passes downwardly through the delivery means.
Claim 6
Dependent Claim
39 words
Apparatus as claimed in claim 3 wherein said rotating coating assembly has an axially located hollow, fluid feed shaft extending within the skirt and wherein said hollow feed shaft is located for rotation within said shaft of said plate.
Claim 7
Dependent Claim
13 words
Apparatus as claimed in claim 1 wherein the plate has a peripheral lip.
Claim 8
Dependent Claim
34 words
Apparatus as claimed in claim 1 wherein the downwardly directed delivery means has a skirt moveable toward and away from said plate so the spacing between the plate and the skirt can be varied.
Claim 9
Dependent Claim
39 words
Apparatus as claimed in claim 1 wherein said rotating coating assembly has an axially located hollow, fluid feed shaft extending within said skirt, and wherein said fluid feed shaft has a distribution block including said radially outwardly directed apertures.
Claim 10
Dependent Claim
20 words
Apparatus as claimed in claim 1 wherein said rotating plate and rotating coating assembly are positioned within a stationary casing.
