Abstract
Abstract A machine for sugar coating articles of confectionery, or pharmaceutical or like products, comprises an annular receptacle having an upwardly open channel section which is resiliently mounted on a support structure so that it can be vibrated with respect to the support structure by means of a vibration generator. The articles to be sugar coated are loaded into the receptacle and vibrated together to spread the sugary substance subsequently sprayed over them. In one embodiment the annular receptacle has a mesh structure so that drying air can be blown upwardly through the articles being coated to accelerate the drying process. In another embodiment the annular receptacle is imperforate and has an arcuate auxiliary container attached thereto, which auxiliary container extends to either side of a discharge aperture of said annular receptacle and is provided with a mesh floor and its own discharge apertures.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
178 words
A machine for coating articles of confectionery, or pharmaceutical or like products, said machine comprising: a support structure; an annular receptacle having a bottom and an upwardly open channel section; means defining a closable discharge aperture in one wall of said receptacle, said closable discharge aperture serving, when open, for the discharge of articles from said annular receptacle. resilient suspension means interconnecting said annular receptacle and said support structure; vibration generator means operating to cause said annular receptacle to vibrate with respect to said support structure; at least the bottom of said receptacle is perforated or has a mesh structure; a container surrounding and locating the said annular receptacle such that there is a space between said bottom of said receptacle and said container; an air duct communicating with said space between said bottom of said receptacle and said container; and a source of air under pressure connected to said air duct, whereby in use of said machine air can be blown into said space between said perforated or mesh structure bottom of said receptacle and said container.
Claim 2
Dependent Claim
178 words
A machine for coating articles of confectionery, or pharmaceutical or like products, said machine comprising: a support structure; an annular receptacle having a bottom and an upwardly open channel section; means defining a closable discharge aperture in one wall of said receptacle, said closable discharge aperture serving, when open, for the discharge of articles from said annular receptacle. resilient suspension means interconnecting said annular receptacle and said support structure; vibration generator means operating to cause said annular receptacle to vibrate with respect to said support structure; at least the bottom of said receptacle is perforated or has a mesh structure; a container surrounding and locating the said annular receptacle such that there is a space between said bottom of said receptacle and said container; an air duct communicating with said space between said bottom of said receptacle and said container; and a source of air under pressure connected to said air duct, whereby in use of said machine air can be blown into said space between said perforated or mesh structure bottom of said receptacle and said container.
Claim 3
Dependent Claim
51 words
The machine of claim 1, wherein said container is upwardly open, all the surfaces of said annular receptacle are perforated or of mesh structure, and said receptacle is rigidly attached to said container; means resiliently mounting said container on said support structure; and means connecting said container to said vibration generator.
Claim 4
Dependent Claim
23 words
The machine of claim 2, wherein said container is annular and has an upwardly open channel section corresponding to that of said receptacle.
Claim 5
Dependent Claim
36 words
The machine of claim 1, wherein said container has a discharge aperture in a position corresponding to that of said discharge aperture in said receptacle, there being means for simultaneously closing or opening both said apertures.
