Problems solved by technology

This leaf moistening method has at least the following deficiencies: ① hot air, moisture or steam are added into the drum at the same time, and the hot air, moisture or steam and the material are all moved along the axial direction of the drum. The heat and moisture exchange intensity is low, the tobacco leaves heat up slowly, and the water diffusion and transfer are slow
②The water sprayed directly by the humidifying device can only cover part of the tobacco leaf surface. In addition, the temperature of the tobacco leaf base is not high, and the water on the tobacco leaf surface cannot be diffused and transferred in time, resulting in uneven moisture in the tobacco leaves and water-stained tobacco on some tobacco leaves.

Embodiment Construction

[0013] As shown in Fig. 1 and Fig. 2, the leaf moistening device of the present invention mainly includes a horizontally arranged drum 1, the drum is preferably placed obliquely, and the feed end is slightly higher than the discharge end. Through holes 2 are uniformly opened on the drum. Set the front section of the drum as the heating section, and the rear section as the humidification section; or set the front section of the drum as the heating section, the middle section as the humidification section, and the rear section as the uniform material section; set it outside the heating section and the humidification section of the drum There are hot air devices 3a, 3b that send hot air into the drum along the radial direction of the drum and humidifiers 4a, 4b that apply moisture, but apply less water or steam to the heating section that mainly functions as pre-moistening and preheating tobacco leaves, so as to reduce the temperature of the tobacco leaves. Crushing, and adding m...

Abstract

The present invention is tobacco moistening through-flow hot blast drum method and apparatus. The drum has through holes, one hot blast device feeding hot blast radially into the drum and one moistening device adding water. Hot blast and water and / or steam are made to enter the drum radially upwards and contact with the downwards falling material for heating and moistening the material, with the excessive moisture being exhausted upwards from the drum. The present invention can produce strong heat and moisture exchange with the tobacco and generate excellent tobacco moistening effect.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf moistening. Background technique [0002] The traditional drum-type hot air moistening method is to feed the tobacco leaf material into the drum, and simultaneously send hot air and water or spray hot steam from the feed end or discharge end of the drum, and continuously turn the tobacco leaves forward in the drum. The material is heated and humidified to achieve the purpose of moistening the leaves. This leaf moistening method has at least the following deficiencies: ① hot air, moisture or steam are added into the drum at the same time, and the hot air, moisture or steam and the material are all moved along the axial direction of the drum. The heat and moisture exchange intensity is low, the tobacco leaves heat up slowly, and the moisture diffusion and transfer are slow. ②The water sprayed directly by the humidifying device can only cover part of the tobacco leaf surface. In addition, the ...
