本文对茶叶精制车间茶尘数量进行了测定,对茶尘的组成和粒度进行了分类分析.结果表明,茶叶精制车间设备近旁茶尘累积量顺序为:风选机＞圆筛机＞抖筛机＞切茶机,但对精制车间设备1.3 m处分析,不同作业环节茶尘的积累量差异不显著(F=0.215＜F0.05(4.30)=5.75).对不同种类的茶尘分析,圆筛机和抖筛机设备近旁的呼吸性茶尘和可吸入性茶尘较低,而吸入性茶尘较高；切茶机近旁和1.3 m处的不同类茶尘所占比重均相同,说明切茶机附近的茶尘分布具有一致性.%The cumulanl of tea dust in tea refining workshop was intermined and its constitution and granularity was analyzed. The results showed, the cumulant of tea dust of these refining equipment was order; winnower > rotary griddle > joggling griddle > tea cutter; At 1.3 meter from the equipment,the cumulant of tea dust of different operation link had no significant differences (F= 0. 215 < Fo 05 (4,30) =5. 75 ). The analysis of the tea dust granularity showed, near to rotary griddle and joggling griddle, suction tea dust was the most and breath and absorption tea dust was lower. Near to and at 1. 3 meters from the tea cutter, the cumulant of the three kinds of tea dust was identical.
