Badaniami objęto sześć rodzajów kołeczkowych zespołów wysiewających stosowanych w siewnikach uniwersalnych. Stwierdzono, że zastosowanie wysiewu górnego pszenicy przy użyciu kołeczkowych wałeczków wysiewających wymaga zwiększenia, w stosunku do wysiewu dolnego ich prędkości obrotowej od 1,3 do 2,1 krotnie. Stwierdzono także, że równomierność dozowania nasion przy dawce 220 kg/ha nie zależy od rodzaju...
The effect of humidification and thermal treatment on the efficiency of coat removal from ground pea seeds was studied. Pea seeds were crushed in a roller mill of the type H 181. Seed coats were separated from the mixture obtained in an air stream. The process of seed coat removal was evaluated taking into consideration the apparent and total efficiency of seed hulling, fraction purity and effective...
In order to remove their coats, white lupine seeds were erushed in a roller mill of the type H 181. The mixture obtained was subjected to pneumatic separation. The process was evaluated taking into consideration the apparent and total efficiency of seed coat removal, fraction purity and effective productivity. The best results of seed coat removal were achieved for seeds which were dried before grinding...
The paper presents the results of preliminary studies on the effect of the inclination angle of a divider board and the linear velocity of a special belt on the separation of rape seeds from field bedstraw seeds. A mathematical formula determining the influence of the belt static load on the separation efficiency is also given. The range of the working parameters of a divider was determined as well:...
