A set of high temperature fast drying (HTFD) equipment for hybrid pennisetum was designed to solve the problem that the hybrid pennisetum is difficult to storage due to high moisture content and problem of large artificial labor intensity and large nutrient loss during natural drying. The calculation of key parameters and design of key components were carried out based on the theory of heat and mass transfer. The control unit was designed through mechanical analysis and FLUENT fluid simulation optimization. The drying test of the equipment was conducted and the final moisture content, water activity, color, crude protein and acid washing were used as evaluation indicators. Then the samples were compared with fresh materials and suncured drying samples. The results showed that the final moisture content of hybrid pennisetum dried by HTFD was (16±1.82)%, the water activity was 0.5648 and the productivity was 2.73t/h. L (brightness/darkness) and b (yellowness/blueness) of hybrid pennisetum dried by high temperature fast drying (HTFD) had no significant difference with fresh material, while a (redness/greenness) was increased by 1.43. The crude protein content and the acid detergent fiber (ADF) content had no significant difference, and the crude protein content was decreased by 0.6 percentage point compared with the fresh material. Compared with the suncured drying, the crude protein content of hybrid pennisetum dried by HTFD was increased by 0.63 percentage point, and hybrid pennisetum dried by HTFD had a good apparent quality. The results showed that the set of equipment could meet the drying demand of hybrid pennisetum, which can improve drying yield and the quality of hybrid pennisetum.
