How to reduce the ash hanging in the middle leaves of Cuibi 1

1. First of all, the asbestos mesh filter was installed at the hot air port of the middle flue-cured leaves of Cuibi No.1, which has filtered out useless substances.

2. Secondly, control the heating speed, usually in rainy days, thin smoke, over-cooked smoke, greedy blue smoke or low-altitude smoke areas, the temperature should be raised quickly, and the low temperature stage before 38℃ should be shortened appropriately.

3. Finally, insist on ventilation. In the yellowing stage, forced ventilation should continue. The fan should run at high speed for 2 ~ 4 hours, and then continue to run at low speed. Reduce the temperature and humidity difference between sheds, and make the tobacco leaves in each shed yellow and dry as evenly as possible.
