한방약재 제조공정에서 발생하는 미세입자 분포 특성에 관한 연구

Abstract

This study investigates ventilation and processing methods for industrial facilities by analyzing the distributionchart and concentration of fine particles generated. Analyses of fine particles were conducted in crushing rooms,sorting room, Primary manufacturing room and packing room, where the concentration of 0.3~10.0 μm particleswere measured for 10 minutes during processing of herb medicines. The result revealed that particles with sizesgreater than or equal to PM2.685 took up most of the space, and the concentration of fine particles (PM10) was1,672.24 μg/m3 in 1th crushing room, 3,144.7 μg/m3 in crushing 2nd room, 262.45 μg/m3 in sorting room, priorto processing (2,302.3 μg/m3 for Aralia continentails and 5,564.9 μg/m3 for Poria cocos), 4,656.5 μg/m3 in Primarymanufacturing room, and 20,213.3 μg/m3 in packing room. The concentration of fine particles generated duringmanufacture of herb medicines was, in comparison to the standard of 150 μg/m3 established in the Indoor AirQuality Control Act, 1.7 to 135 times higher. High concentrations of fine particles were found in all rooms, exceptfor packing, even with partial ventilation. Also, it can be inferred that adequate deodorization system may berequired in order to control unpleasant herb odors. Through this study, it is recommended that the use of scrubbersand concealment may facilitate control of fine particles containment.
