Apricot is a very important fruit for production and trade in Xinjiang, China. Xinjiang is the largest apricot producer in total annual production and planted area. However, the fresh apricot is very liable to become putrid and perished during storing and transporting. And the losses of apricot perished in total annual amount accounted for about 20% during transporting, marketing and storing after harvest. Thus, it is clear that fresh apricot processing, especially in the planted sites has become the most important measure and the major bottleneck for apricot industry in Xinjiang. Traditionally, fresh apricots can be processed into various special flavor apricot products, including dried apricot slices, preserved apricots，canned apricots and apricot jams, which are very favorable. One among the apricot products is the dried apricot slices, represent of the local color apricot products processed. Based on the combination theory of agricultural machinery and agronomy as well as the related basic study, this research was conducted to determine the optimal structure and design parameters of the dynamic orientation device for fresh apricots in the light of study of the physical and mechanical properties of apricot during transporting and segueing, and to develop the dynamic orientation device for fresh apricot. And self-orientation mechanism was proposed based on principle of least action principle and apricot’s physical properties. The differential speed conveying mechanism and interaction of friction with belt for fresh apricot were analyzed. The apricot’s orientation position can be adjusted by orientation belt and clamp belt during conveyance process. Structure of apricot orientation device was schemed, including clamp belt, orientation belt, slope plate, clamp gap adjustment component, belt tension adjustment components and other auxiliary components. All those components created orientation channel. The clamp gap and belt tension can be changed by adjusting the adjustment components. Line speed of clamp belt and orientation can be controlled by adjusting the current frequency of converter. Saimaiti apricot was taken as research object. Orthogonal test was designed. The test factors were speed ratio of orientation belt to clamp belt, gap between two paralleled clamp belt and size of apricot. Test indexes included orientation rate and cutting rate. Experimental results showed that the best combination level can be as follow： speed ratio of orientation belt to clamping belt was 6.52, clamp belt gap was 15mm, interval size of apricot short-axis diameter was 32.1~35.0mm. The orientation accuracy rate was 87.4% and cutting accuracy was 85.6% accordingly. The results provided a reference for dynamic orientation research which based on belt conveyance for apricot.
