Abstract: An experiment was carried out to investigate the performances of seven temperature and humidity auto-control equipment in bulk curing barn. Results showed that JKM-B and TMC-4 had more control-points than others, while the stability of QZK3000-82, ARC-III and BZK was superior to others. QZK3000-82, JKM-B, ARC-III, TMC-4 and SWP-ZN-C3 were easily handled while E and F were difficult. ARC-III and TMC-4 had the highest energy consumption, BZK and SWP-ZN-C3 the lowest, while QZK3000-82, JKM-B and KX200 the medium. The seven equipments in the experiment exhibited favorable control capacity to meet the reqirement of tobacco leaf curing. Cured leaves with high quality were obtained in the bulk curing barn with QZK3000-82 or ARC-III. The performances of ARC-III and QZK3000-82 were superior to the others in comprehensive evaluation.
