Abstract

During the process of tea vibration sieving, the instability of tea flow has great influence on the sieving efficiency, which contains the sieving quality and sieving productivity. In this paper, the influence factors on the sieving efficiency in tea vibration sieving were studied. Firstly, the mechanism analysis of tea vibration sieving was conducted. Through the force and motion analysis of the tea particles, the sieving model of the stripe-shape tea particles was established to study the influence of vibration angle, rotation speed and acceleration in the sieving rate. Next, the tea vibration sieving process was simulated by the Matlab/Simulink to analyze the relationship between tea flow rate, rotation speed of tea vibration sieving machine and sieving efficiency. Finally, the theoretical analysis results were well verified by the experiments. The research results provide a certain theoretical foundation for designing and improving the tea vibration sieving machine, and can be used to guide the optimization of operation parameters.
