DEVICE AND METHOD FOR SPECTROMETRICALLY MOBILE MEASUREMENT OF CEREALS, OLEAGINOUS OR DERIVATIVE PRODUCTS RELATING TO THE AGRO-FOOD SECTOR

摘要

The constraints of a mobile spectroscopic measurement device of samples lies in the need for a perfect mechanical stability of the light source which must not deviate during any vibrations; and in the perfect sequential flow of the sample in the reading chamber subjected to the same vibrations. The device according to the invention overcomes these disadvantages. It consists of a light source (15) adjusted and blocked by orientable plates (17), (18), (19) contiguous to a grain sample reading chamber composed of walls (21), (22) ), (23) and (23), the blocking and the evacuation of the grains are ensured by a rotary shutter cylinder (25) and a cylinder support (26). The sample flow system in the reading chamber is composed of a rotary shutter cylinder (5), a cylinder support (8), whose rotation of the cylinder (5) in its support (8) , allows the opening or closing of the passage of the sample. The device according to the invention is particularly intended for mobile applications for spectrometric measurement and / or passage of seeds in continuous passage, without the number of applications being exhaustive.
