| Abstract: |
| To solve the almond shelling machinery possess issues of low productivity, low shelling rate, and kernel damage, this study based on nuts shelling principle and used large almond wood (referred to as ‘Shache No. 3’) as the object to design the almond grading shelling machine. Almond size, shelling force loading direction and speed,and almond moisture content of the material characteristics were analyzed. The results showed that the shelling machine between the two rollers distance and moisture content on the shelling force and deformation of almond had a significant impact. Using the experimental method to optimize the working parameters of the grading and shell breaking mechanism, when the distance between the two rolls was adjusted to 14 mm for level I, 13 mm for level II and 12 mm for level III, the water content was controlled in the range of 9.8%～10.5% and the rotational speed was 1 000 r·min-1, the average shell breaking rate was measured as 95.57%, and the average breakage rate was 3.37%, which met the actual production requirements. |
