Description

TECHNICAL FIELD

[0001] The utility model relates to tobacco leaf processing device technical field, especially in kind of hot air leaf moistening machine. BACKGROUND

[0002] Hot air leaf moistening machine is a kind of equipment used in cigarette processing and manufacturing, and the heating and humidification treatment of tobacco leaf are realized by hot air circulation system, the humidity and temperature of tobacco leaf are increased, the toughness of tobacco leaf is improved, the breakage rate of tobacco leaf in processing process is reduced, and the quality and processing efficiency of tobacco leaf are improved.

[0003] The existing hot air leaf moistening machine adopts horizontal air inlet mode, and the following deficiencies exist:

[0004] 1, horizontal air inlet mode is not conducive to the uniform heating and moisture absorption of tobacco sheet.When humid hot air enters the drum along the horizontal direction, it is usually concentrated in the lower area of the drum, and the tobacco leaf in the upper area is difficult to fully contact the hot air, resulting in uneven temperature and humidity of tobacco leaf, which affects the leaf moistening effect.

[0005] 2, horizontal air inlet mode is prone to condensate, which affects the quality of tobacco leaf and production efficiency.Horizontal air inlet can cause higher humidity in the lower area, produce condensate, cause water stains on the surface of tobacco leaf, and affect the quality of tobacco leaf.In addition, the condensate also increases the humidity in the drum, causing the tobacco leaf to adhere to the drum wall, affecting the production efficiency.

[0006] 3, horizontal air inlet mode increases the waste of energy.Because the humid hot air does not fully contact the tobacco leaf, in order to ensure the relative stability of hot air temperature, the steam injection amount needs to be increased.Meanwhile, due to uneven distribution of hot air, the hot air temperature in the lower area is too high, and the temperature in the upper area is insufficient, which increases the waste of energy in this unbalanced heating mode, causing the effective utilization rate of energy to decrease significantly.
