The biological features of oil-tea camellia fruit were studied. According to the features, the extruding, grind and rub way were adopted to design an oil-tea camellia fruit dehulling device with tapered roller structure. The water content and velocity of roller were the main factors affecting the results of dehulling for oil-tea camellia fruit. The fitting dehulling conditions were confirmed as follows: water content 40%-60%, velocity of roller 120-180 r/min. Under these conditions, the dehulling rate was more than 92%, and the output was more than 2 t/h. |
