Problems solved by technology

A general airflow dryer includes a heater, a drying pipe, and a separator. However, the drying pipe of this kind of dryer is generally set horizontally at the front end, and the middle and rear sections are gradually bent and raised. This kind of gradual drying pipe needs to be set sufficiently. long, and therefore, higher manufacturing costs

Embodiment Construction

[0029] In order to better understand the present invention, the present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited to the scope described in the examples.

[0030] Such as figure 1 As shown, the airflow drying device of the present invention includes a combustion furnace 1, one end of the combustion furnace 1 is connected with a horizontal drying pipe 2, and the horizontal drying pipe 2 is connected with a vertical drying riser 4 through an elbow 3, and the vertical drying The riser pipe 4 is connected to a cyclone separator 5 . The hot air generated in the combustion furnace 1 is blown into the horizontal drying pipe 2 to heat and dry the shredded tobacco entering the horizontal drying pipe 2 . Wherein, the combustion furnace 1 can also be replaced by other airflow heaters. The elbow 3 is an arc-shaped connecting portion.

[0031] A feed pipe 6 is arranged on the side of the e...

Abstract

The invention discloses a pneumatic drying device, which comprises a pneumatic heater and a cyclone separator. The bottom of the cyclone separator is provided with a discharge tube; the pneumatic heater is connected with the cyclone separator through a horizontal drying tube and a vertical drying ascending tube; the horizontal drying tube is connected with the vertical drying ascending tube through an arc-shaped connecting part; one side of the arc-shaped connecting part close to the horizontal drying tube is provided with a feed pipe, the feed pipe is provided with a steam jet; the steam jet is communicated with a steam source; and the curvature radius of the arc-shaped connecting part is 0.55 to 0.8 meter. The pneumatic drying device saves the tubing of the drying tube without causing cut tobacco loss in the drying process.

Description

technical field [0001] The invention relates to shredded tobacco drying equipment, in particular to an airflow drying device. Background technique [0002] At present, in the cigarette processing process, drying shredded tobacco is an essential link, and its treatment effect has a direct impact on the sensory quality of cigarettes. Therefore, shredded tobacco should be dried to make its moisture content meet the standard. In order to dry shredded tobacco, drum dryers and airflow dryers are generally used. Compared with drum dryers, airflow dryers can dry shredded tobacco in a short period of time. Therefore, the drying capacity is high and the productivity of cigarettes can be improved. A general airflow dryer includes a heater, a drying pipe, and a separator. However, the drying pipe of this kind of dryer is generally set horizontally at the front end, and the middle and rear sections are gradually bent and raised. This kind of gradual drying pipe needs to be set sufficient...
