Abstract:
Apparatus for examining flowable material comprising:a) a tube having:i) a first opening for receiving said material,ii) a second opening for discharging said material, andiii) a tube segment having opposite side walls and disposed between said openings for holding material;b) a measuring device disposed adjacent said tube segment and having:i) a light source adjacent one side wall of the tube segment to transmit light of a wavelength range to be examined along a beam path and through said tube segment, andii) a light receiver adjacent the opposite side wall of the tube segment to measure the effect upon said light transmitted along said beam path of said material when placed in said tube segment;c) the walls of said tube segment aligned with said beam path between the light source and the light receiver being made of a material that is translucent or transparent for said wavelength range of the light to be examined;d) a recording unit connected to said measuring device and adapted to record individual measurement values or sets of measurement values for said material placed in said tube segment; ande) a conveyor for conveying said material received through said first opening to said tube segment and for building up a pressure of more than 200 kPa in said material when in said tube segment.
