In agricultural facility, which are equipped with mechanical and closed ventilation systems, have faced the challenge to reduce fine dust concentration for enhancing working environment. Among the dust sources, fruit fuzz, characterized by its dense and needle-like structure, can induce allergic symptoms in agricultural workers upon exposure to their respiratory systems and skin, adversely impacting their health and deteriorating the work environment. The focus of this research is the development of a fine dust reduction system aimed at enhancing the working conditions. The system operates by generating a downward airflow to prevent fine dust from reaching the workers' respiratory systems. To assess the efficacy of the fine dust reduction system, real-time measurements of dust concentrations were conducted at commercial peach sorting stations, both before and after the operation of this system. The findings revealed that during peach sorting task, the total dust concentration was 6.89 times higher than the normal condition, representing the critical need for reducing fine dust levels. The deployment of a particulate matter reduction system specifically within the fruit sorting area, a section identified for substantial dust generation due to the removal process of fruit covering bags, has led to a substantial decrease in airborne particulate concentrations. This targeted intervention resulted in an 80.4% reduction in Total Suspended Particulate (TSP) levels and a 60.3% decrease in PM-10 concentrations at the site of implementation. Additionally, a broader assessment across the entire sorting facility revealed a significant decline in fine dust levels, with TSP concentrations diminishing by 67.6% and PM-10 concentrations by 52.2%. This research underscores the efficacy of targeted fine dust control measures within agricultural facilities, markedly enhancing air quality and the occupational environment for agricultural laborers.
