Abstract: The invention provides a device (10) for acquiring images of a plant, which device comprises: i) a first structure (60) defining a cavity (33) for receiving a portion to be imaged of the plant, the cavity presenting a longitudinal axis (13) and an opening (65) at one of its ends, the cavity being defined by at least one transparent wall forming a window (12) for observing the portion to be imaged; ii) a second structure (61) extending around the window (12) and mounted to move in translation along the longitudinal axis (13) relative to the first structure, and comprising: hollow reflective optics (11, 19) extending around the window and including a reflecting surface (19) directed towards the longitudinal axis; and a plurality of image sensors (18) regularly distributed around the window (12), the field of view (77) of each sensor including at least a portion of the reflective optics so as to capture images of the portion of the plant that is surrounded by the window, which images are reflected by the refl

Abstract: A process for simplified production of a reference milling for determining the milling quality of wheat, includes: a first crushing of a wheat sample; a first sieving of the crushed product into three distinct levels of particle size; a second crushing of oversize particles resulting from the first crushing; a second sieving of the oversize particles thus crushed; a mixing of coarse semolina resulting from the sievings; a third crushing of the mixture of the coarse semolina; a third sieving of the mixture of the coarse semolina thus crushed into two distinct levels of particle size; a mixing of fine semolina resulting from each of the three sievings; a fourth crushing of the mixture of fine semolina; a fourth sieving of the mixture of the fine semolina thus crushed into a single level of particle size; a mixing of the flours resulting from sievings, the mixture constituting the desired milling.
