| Compost compression processes, such as pelleting, increase bulk density, improve storability, reduce transportation costs and make easier materials handling using existing equipment for handling and storage of grains. It is important to prevent quality deterioration of pellets in long time storage. Therefore, it is necessary to reduce the moisture content of the pellets to less than or less. In this research the drying kinetics of compost pellets were studied at air temperatures of 50, 60 and 70 , air velocities of 0.5, 1 and 1.5 , particle sizes of 1.18 and 2 mm and pellet diameters of 6 and 8 mm. The maximum effective moisture diffusivity (1.78× ) was obtained at air velocity of , air temperature of 70 , particle size of 1.18 mm and pellet diameter of 8... |

| Compression is important to prevent a deterioration in quality pellets for long term storage and the moisture content of the pellets must be reduced to or less. In this research the quality of pellet of compost was studied at air temperatures of 50, 60 and 70, air velocities of 0.5, 1, and 1.5 m/s, particle sizes of 16(1.18mm) and 10(2mm) and pellet diameters of 6 and 8 mm. The Taguchi quality engineering method was used to investigate the effects of parameters on compressive strength of pellet. An orthogonal array, signal-to-noise (S/N) ratio analysis of variance (ANOVA) were employed to analyze the effect of these compressive strength parameters. Thus, the optimal performance for the compressive strength of pellet was obtained at first level of factor... |
