Abstract: The main heat loss routs of bulk curing barn unavailable heat consumption are removing moisture and exhausting smoke, which are also the cut-in points to improve energy utilization efficiency in bulk curing barn. According to current condition of large coal consumption and low energy efficiency, technology application situation and developments of removing moisture and exhausting smoke were introduced, including working principle and technical characteristics of present installations. The exiting problems were summarized, including low productivity, unsatisfactory operation effect and high equipment investment. Finally, development suggestions were put forward, such as applying mature technologies to agricultural engineering, systematically recycling the waste heat in chimney and moisture removing to realize the internal circulation in bulk curing barn.
