Multiple drying rooms are gathered together to facilitate unified power supply and save costs. Unified management improves the quality of flue-cured tobacco and also saves land. However, due to , multiple curing rooms are gathered together, and each curing room needs to be equipped with a heat pump. Since the flue-cured tobacco process is divided into three stages: yellowing, color fixation and drying, the temperature required for the yellowing stage is 36 to 44°C. ℃, the temperature stabilization time is 49~104 hours, the temperature required in the fixation stage is 46~54℃, the temperature stabilization time is 20 hours, the temperature required in the drying stage is 60~65℃, the temperature stabilization time is 20 hours , therefore, the two stages of color fixing and drying require larger-power heat pumps. During use, the common practice is to equip a baking room with a 15-horsepower heat pump. When a single baking room often undergoes large-scale dehumidification, It is necessary to start the heating rod for auxiliary heating, and the auxiliary heating energy efficiency is low, and the high-energy-efficiency heat pumps of other baking rooms in the yellowing stage are sometimes on and sometimes off (usually the heat pumps in the yellowing stage are only turned on for about 4 hours a day), so Large energy consumption.
