Device for preparing reconstituted tobaccos by multi-point air inlet type thick slurry method and operation method of device

Abstract

The invention discloses a device for preparing reconstituted tobaccos by a multi-point air inlet type thick slurry method. The device sequentially comprises a raw material storage tank (1), a formingand drying device (2), a stripping device (3) and a winding device (4). The device is provided with a plurality of hot air fans (271i); each hot air fan (271i) is connected with a ventilation pipe (272i) extending towards a formed steel strip (21) in the direction perpendicular to the formed steel strip (21); the angle between the direction of hot air blown by a pipe opening (273i) of each ventilation pipe (272i) and the operation direction of the reconstituted tobaccos is 90-180 degrees; and the temperature and quantity of the hot air blown by each hot air fan can be independently adjusted. The device can be used for forming, drying and preparing the reconstituted tobaccos for heat-not-burn cigarettes into samples, and provides support for research of the heat-not-burn cigarettes.

Description

technical field [0001] The invention belongs to the technical field of production and processing of reconstituted tobacco leaves, and in particular relates to a device for preparing reconstituted tobacco leaves by a multi-point air-intake type thick slurry method and an operation method thereof. Background technique [0002] With the acceleration of the global tobacco control campaign, the global tobacco industry has entered a new period of seeking change and breakthroughs, which has also promoted and accelerated the research and development of new tobacco products, mainly including heat-not-burn cigarettes, electronic cigarettes, and snus. Heat-not-burn cigarettes are an important part of new tobacco products. [0003] Compared with granular and traditional shredded tobacco as tobacco segment materials, reconstituted tobacco leaves have the characteristics of strong plasticity, homogenization and high controllability while maintaining the active ingredients of natural tobac...

Problems solved by technology

The problem is that there is only one hot air inlet, and the closer to the beginning of the drying process, the hot air has already absorbed a lot of water, resulting in weaker moisture absorption capacity and poorer drying efficiency

The existing problem is: when the hot air flows from right to left in the ventilation tunnel 6, the air volume is increasing, and the hot air volume Q4'=Q1+Q2+Q3+Q4 at the leftmost end of the ventilation tunnel 6, but in the actual application process, the flow The slurry flowing out of the pulp box (with a moisture content of 70%-80%) first forms a size film, and when the conveyor belt runs from left to right, the size film is gradually dried into reconstituted tobacco leaves, so in this device The leftmost end of the ventilation tunnel 6 is jus
