Problems solved by technology

The advantage of this type of method is that the moisture content of the material is uniform after regaining moisture, but all materials need to be loosened in advance, resulting in large fragmentation during the loosening process, which significantly increases the loss rate of the processing process

Embodiment 1

[0055] Example 1: Tobacco leaves purchased from the tobacco leaf site, due to the long storage time, the moisture content loss is easy to break. The present invention is added before rebaking production, and the tobacco leaf material (generally packed with hemp flakes, with a weight of 40kg per package) is evenly placed on the conveying mechanism, and the conveying mechanism conveys the material to the moisture regaining equipment, and the conveying part of the moisture restoring equipment After the material is accepted, it is sent into the tempering machine box. By adjusting the amount of steam and water added, the temperature of the internal environment of the box is controlled at 40-70°C (adjustable), and the relative humidity is 70-100% (adjustable) RH, and the materials pass through in an environment with relatively high temperature and humidity. Water osmosis and heat exchange, temperature and moisture content are increased.

Embodiment 2

[0057] Example 2 : Tobacco leaves after threshing and rebaking, in order to facilitate storage and natural aging of tobacco leaves, the moisture content is controlled at 12-13%, but the moisture content will decrease during storage, especially in winter and spring, the surface of some cigarette pack materials The moisture content will be lower than 10%, and it will be severely broken during the feeding process of silk making. The present invention is added to the feeding link of the silk production line, and the tobacco leaf material (usually boxed, with a weight of 200kg per box) is automatically placed on the conveying mechanism after the manual or logistics system removes the packaging, and the conveying mechanism conveys the material to moisture regain Before the equipment, the conveying part of the dampening equipment takes over the materials and sends them into the dampening machine box. By adjusting the amount of steam and water added, the temperature of the internal ...

Abstract

The invention relates to a method and equipment for pre-moisturizing the surface of tobacco materials, in particular to a method and equipment for pre-moisturizing (increasing temperature and humidifying) the surface of tobacco materials by using steam without changing the shape of tobacco materials. The equipment consists of a conveyor, a moisture recovery box, a heating and humidifying system installed in the moisture recovery box, a waste steam discharge system, a condensed water collection and discharge system, and a control system installed outside the moisture recovery box. The moisture recovery box is a long kiln body as a whole The middle part of the moisture regain box is a moisture regain channel with openings at both ends. One end of the moisture regain channel is the discharge door, and the other end of the moisture regain channel is the feed door. A conveyor belt is connected to the bottom of the moisture regain channel of the moisture regain box. A waste steam discharge system is installed at both ends, and several soda nozzles are installed on the top and both sides of the moisture resurfacing box. When the material passes through or stays in the moisture regain channel, a certain amount of steam and water are applied to increase the temperature and moisture of the material, which is beneficial to subsequent processing.

Description

technical field [0001] The invention relates to a method and equipment for pre-moisturizing the surface of tobacco materials, in particular to a method and equipment for pre-moisturizing (increasing temperature and humidifying) the surface of tobacco materials by using warm and humid gas without changing the shape of tobacco materials. It belongs to the technical field of tobacco pre-moisture treatment. Background technique [0002] The moisture content of tobacco leaves after rebaking is generally controlled within the range of 12-13%. In areas with low air humidity, the moisture content of tobacco leaves will continue to decrease during storage, especially the loss of moisture content of tobacco leaves on the surface of tobacco bales will be more prominent. In Chuxiong area as an example, the moisture content of the surface material of the tobacco bale in winter and spring is only about 9-10.5%, and the material inside the core is slightly better; The length of production...
