This work shows recording method of dynamic load (impact) in grains on a single frame of film. Grain load photographs were taken with a photographic still camera through a slotted revolving disk, using two flash lamps. The photograph yielded eight images (pictures) of the loaded grain, allowing - among other things - to calculate the velocity of grains following the impact.
This paper presents the results of the study on seed losses in lentil occuring in mechanized multiphase graded collection. The harvest consist of four operations which caused different losses of lentil’s seeds. The minimal seed’s damage was obtained during threshing with a moisture content of 14.5 %.
