Section drying cut tobacco equipment and method

Abstract

The invention provides section drying cut tobacco equipment and a section drying cut tobacco method, which can keep enough hot air drying efficiency. The equipment main body is a two-section cylinder dryer; materials are fed through a feed port of the cylinder dryer by a vibrational fluidized bed; the front bed body of the vibrational fluidized bed extends into a feed cover of the drying cylinder; a bed surface bottom plate of the vibrational fluidized bed body which extends into the drying cylinder has a net plate structure; a hot air port is formed on the lower part of the net plate; and the hot air is blown from the lower part of the net plate into the drying cylinder. The section drying cut tobacco method comprises the step of drying through hot airflow in the feeding process before high and low temperature section drying of the drying cylinder. Due to the adoption of a multi-stage section drying mode, the section drying cut tobacco equipment and the section drying cut tobacco method are favorable for uniformly drying the cut tobacco, make the whole airflow drying process strengthened, and also make low-temperature drying of cut tobacco possible.

Description

[0001] Technical field: [0002] The invention relates to a device for segmentally drying shredded leaves in the tobacco shredded production process, and also relates to a method for segmentally drying shredded leaves. Background technique: [0003] Shredded leaf drying is an important process in the tobacco shredded production process. The goal of the shredded leaf drying process is to remove part of the water in the shredded leaf to meet the specified moisture requirements and accuracy, while increasing the filling value of the shredded leaf, reducing the irritation and miscellaneous gas of the shredded leaf, and improving the odor absorption of the shredded leaf. [0004] At present, there are two main types of shredded shredded drying equipment, tower tube shredded shredded air drying and single-stage drum shredded shredded drying. Tower-tube airflow drying of leaf shreds is a process in which the leaf shreds are continuously added into the drying pipe, and the moist...

Problems solved by technology

The hot air described in this plan enters the cylinder from the middle section of the cylinder and moves to both ends of the cylinder. During the movement, the temperature of the hot air is continuously decreasing. When the material is thrown downward from the high point of the cylinder, only some The material is in contact with the hot air to absorb heat energy, and the subsequent hot air will find a material-free area with less resistance and converge toward the tide outlet. The effect of hot air drying is poor, especially in the latter part, which is dominated by hot air drying, and it is difficult to obtain uniform moisture content. The product

Secondly, the hot air pipe is inside the drum, and it is difficult to effectively clean the material entering the hot air pipe during the throwing process, which will eventually lead to the blockage of the hot air pipe

The material is sprinkled on the middle hot air pipe by the drum and sprinkled again, which will also cause the secondary shredded tobacco to be broken
