Abstract
Abstract A method of and an apparatus for sugar coating, the apparatus comprising: a rotatable vessel for containing a material to be coated; a baffle 9 movable independently of the rotatable vessel; a baffle mounting shaft 10 having a bent construction, for mounting the baffle 9 thereon; and a hydraulic cylinder for rocking the baffle mounting shaft 10 to displace the baffle 9. Load cells 17a and 17b for detecting the position of the baffle 9 relative to an accumulated layer M of a material to be coated are provided on the baffle 9. The load cells 17a and 17b serves for holding the position of the baffle 9 relative to the accumulated layer M of the material to be coated at all times, on the basis of a load imposed due to the presence of the contact with the material to be coated.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
125 words
A pan coating apparatus for sugar coating, comprising: a rotatable vessel for containing a material to be coated; a baffle means movable automatically and independently of the rotatable vessel; a baffle displacing means which can perform at least two displacements of the baffle means, including displacements in reverse directions from each other, during each one cycle of the coating process; and, sensor means for detecting a position of said baffle relative to a surface of an accumulated layer of the material to be coated, said baffle displacing means displacing said baffle means in response to said sensor means so that a part of said baffle means is inserted into said accumulated layer and another part of said baffle is maintained outside of said accumulated layer.
Claim 2
Dependent Claim
125 words
A pan coating apparatus for sugar coating, comprising: a rotatable vessel for containing a material to be coated; a baffle means movable automatically and independently of the rotatable vessel; a baffle displacing means which can perform at least two displacements of the baffle means, including displacements in reverse directions from each other, during each one cycle of the coating process; and, sensor means for detecting a position of said baffle relative to a surface of an accumulated layer of the material to be coated, said baffle displacing means displacing said baffle means in response to said sensor means so that a part of said baffle means is inserted into said accumulated layer and another part of said baffle is maintained outside of said accumulated layer.
Claim 3
Dependent Claim
47 words
The apparatus for sugar coating as set forth in claim 1, wherein: said rotatable vessel is rotated substantially about a horizontal shaft and a porous ventilating portion is formed in a wall of said rotatable vessel to ventilate the accumulated layer of the material to be coated.
Claim 4
Dependent Claim
48 words
The apparatus for sugar coating as set forth in claim 1, wherein: said baffle displacing means includes (1) a baffle mounting shaft having a bent construction and mounted thereon to the distal end thereof with said baffle means, and (2) an actuator for rocking said baffle mounting shaft.
Claim 5
Dependent Claim
46 words
The apparatus for sugar coating as set forth in claim 3, wherein: said baffle mounting shaft has a construction of being bent into substantially L shapes at plural positions of said shaft, and said actuator consists of a hydraulic cylinder for rocking said baffle mounting shaft.
