Abstract: Tea dust is defined as the mixture of powder, dust and smoke. In this paper, firstly, the course, density, size characteristic and physicochemical properties of tea dust were introduced with the special emphasis on its origin, delivery and accumulation effect. Based on tea, as a special material and efficience-safety-clean tea production in optimized layout factory, Secondly, relevant control measures were discussed against tea dust emission from shaking sieve machine, plane screening machine, flat stitch screening machine, cut tea maker, drifting-sifting machine and uniform heap packing machine. And subsequently, we reviewed the use of new technologies in dust control such as ultrasonic atomization, bag filter, electrostatic precipitation and acoustic cleaning and results showed solo-technique application was not efficient to prevent tea dust contamination because of various traits of dust in the process of tea making. Thus, we suggest that tea dust control requires a set of combined measures and evaluating indicators, which helps efficience-safety-clean tea production in future.
