摘要：In view of many problems caused by the traditional "coal + electricity" flue-cured tobacco method, such as the environmental pollution, the high cost, the unguaranteed quality, and the demanding reliability of power supply, the researcher put forward the heat pump energy-saving flue-cured tobacco technology based on the field investigation. The technology equipment, including heat pump, condensing and draining roasting room and self-control system, uses smokeless hot air as medium to realize the drying of tobacco leaves, which solves the quality problem of residual sulfur in products. Moreover, the energy saving effect is remarkable, nearly 70% of the heat in the process of dehumidification is recycled. At the same time, the baking performance is stable, and the various indexes can be effectively and accurately realized to ensure the quality of the tobacco leaves. It only consumes 2kW h of electricity to dry 1kg of tobacco leaves. Compared with traditional method, it's conducive to environmental protection.
