Abstract:
Device (1) and method for sparse feeding of bulk materials such as cereal grains, in particular rice to a processing and/or analysing machine (2) comprising in flow direction of the bulk material means (3) for branching a partial flow (P) of bulk material off a main flow (M) of bulk material and means for conveying (4) the branched-off partial flow (P) to the processing and/or analysing machine (2), whereby the means for branching off (3) and the means for conveying (4) are arranged such that a heap of branched-off bulk material is formable at the transition between the means for branching off (3) and the means for conveying (4).
Abstract:
The present invention relates to a method and an arrangement for measuring the smoothness of grains. In one embodiment, the arrangement includes a channel for supplying grains, especially rice grains, an obstacle arranged at the channel to slow down grains falling on the obstacle, so that the flow of grains forms a heap on the obstacle and an image capturing device placed facing the obstacle. The image capturing device is arranged to capture an image of the heap, where the area under the curve of the captured heap image indicates the degree of smoothness of the grains or the course of the curve of the captured heap image indicates the degree of smoothness of the grains.
