Drying equipment and using method thereof

Abstract

The invention discloses drying equipment. The drying equipment comprises a fluidized bed (1) and a condenser (4), wherein the fluidized bed (1) is in the shape of an inverted trapezoid, a heat dissipation tile plate is arranged in the fluidized bed, a gas exhaust tube (8) is arranged on the upper part of the rear end of the fluidized bed (1); the condenser (4) is a heat exchanger, one end of the condenser (4) is connected with the bottom of the front end of the fluidized bed (1) through a dehumidifying air inlet tube (9); the other end of the condenser (4) is an air inlet tube (2); and a waterinlet tube (5) and a water outlet tube (6) are arranged on the bottom of the condenser (4). The invention further discloses a using method of the drying equipment. The equipment disclosed by the invention is used to cool and dry cigarette cut tobaccos which are heated to not combust, so that dried cut tobaccos are quickly shaped, and the dried cut tobaccos further can be quickly dehumidified anddried.

Description

technical field [0001] The invention belongs to the related field of tobacco production, and in particular relates to a rapid cooling and drying equipment for heat-not-burn shredded tobacco and an application method thereof. Background technique [0002] In recent years, with the independent innovation of heat-not-burn tobacco products, the output of reconstituted tobacco leaves has continued to increase, and the scope of its use has also continued to increase. The papermaking process of reconstituted tobacco leaves in the prior art is generally based on process requirements, mixing papermaking reconstituted tobacco leaves and natural tobacco leaves together, and then making shredded tobacco through a series of processes such as moisture regain, feeding, shredding, and drying. The feeding step is for the shredding step to be carried out easily, and the feeding is to add fuming agent and flavor essence; but after the shredding step, the moisture content in the shredded tobacc...

AI Technical Summary

Problems solved by technology

The papermaking process of reconstituted tobacco leaves in the prior art is generally based on process requirements, mixing papermaking reconstituted tobacco leaves and natural tobacco leaves together, and then making shredded tobacco through a series of processes such as moisture regain, feeding, shredding, and drying. The feeding step is for the shredding step to be carried out easily, and the feeding is to add fuming agent and flavor essence; but after the shredding step, the moisture content in the shredded tobacco is relatively large, which cannot meet the requirements of low-temperature non-burning tobacco products (generally heat-not-burning tobacco products have a high moisture content). the lower the moisture content, the better)

Wherein the drying step generally uses air at a higher temperature and uses high-intensity means such as air with a large air volume to operate to improve drying efficiency (that is, the moisture content of the shredded tobacco is easy to meet the requirements); but the air at a high temperature and the air with a large air volume also make Oily substances such as smoking agents and flavors and flavors of various flavors contained in shredded tobacco evaporate at high temperature, and shredded tobacco becomes brittle and indeterminate, which brings about the maintenance of aroma and the improvement of sensory quality of the obtained heat-not-burn shredded tobacco.
