A model to predict the shearing/crushing force of an existing horizontal mechanical digester used for pulverization/digestion or maceration of date palm fruit was developed in the study. The model accurately predicted the shearing force used in digestion of fruit with model simulation done using Matlab 7.9 (R2009b). The results obtained showed a linear relationship between shearing force and angular velocity of implements/beater arms which are components of the digester that did the shearing of fruit mesocarp. It was also observed from results obtained that the higher the magnitude of angular velocity of shearing implement the higher the magnitude of shearing force of the digester. An angular velocity of 15.71 rads-1 yielded a shear force of 400.00 kN with an angular velocity of 34.56 rads-1 yielding a shear force of 880.00 kN. It was reported by the literary world that high magnitude of shear force is more efficient in pulverization process than shear force of low magnitude.
