The airflow characteristics of clean tunnel type clean room were experimentally investigated with the change of operating speed and exit type. Distributions of air velocity and pressure were measured in clean room which is located lower than HEPA filters, and the pressure distribution was also measured in upper plenum which is located above the HEPA filters, to identify the performance of clean room. Through the analysis it was turned out that air velocity characteristics in clean room were significantly affected by the upper plenum flow conditions such as pressure distribuion. This results will be useful in the actual clean room design to enhance the performance.

Worldwide consumption of vegetable soybean has been increasing recently, but in the process of vegetable soybean production, threshing and separation work accounts fur about $80\%$ of overall labor. Therefore, developing of the vegetable soybean thresher is necessary to reduce the cost of labor. The main objective of this study is to acquire the basic in-formations for design of the vegetable soybean thresher which is suitable for domestic circumstances. We made the experimental system to investigate the threshing and separating performance at the several speeds of threshing cylinder and separating blower according to the kinds of threshing tooth. The result are as follows; Threshing performance of vegetable soybean thresher was shown as the best in case the threshing tooth made of rubber which has the 80 of Shore hardness was used at the circumference speed of cylinder of 5.8$\~$8.1m/s. Also separating cleaning performance of vegetable soybean thresher was shown as the best at more than 1,300 rpm of blower speed and $60\~80\%$ of opening ratio of suction port.
