Description
Technical Field
The utility model belongs to the technical field of tobacco production, concretely relates to low temperature cut tobacco drying device of pipe tobacco.
Background
The reconstituted tobacco is a main raw material for circumferentially heating non-combustible cigarettes and has the following characteristics: the comprehensive utilization rate of tobacco raw materials can be effectively improved; secondly, the cigarette oil material has better adsorbability to smoke agents, propylene glycol and other oily materials for cigarettes; preparing tobacco shred products with different tastes according to different requirements; fourthly, the harmful substances such as tar content and the like can be greatly reduced by heating the non-combustible smoke in the circumferential direction. In recent years, with the self-innovation of circumferential heating non-combustible cigarette products, the yield of reconstituted tobacco is continuously increased, and the application range of the reconstituted tobacco is continuously increased. The existing tobacco shred forming process for paper-making reconstituted tobacco generally mixes the paper-making reconstituted tobacco and natural tobacco together according to process requirements, and then the tobacco shred is made into cigarette tobacco shreds which are not combusted by heating through a series of procedures such as moisture regain, feeding, shredding, drying and the like.
The patent CN101828762A discloses a tobacco shredding process and equipment for paper-making reconstituted tobacco, and provides a new tobacco shredding process and equipment for paper-making reconstituted tobacco aiming at the defects of the paper-making reconstituted tobacco manufacturing and production application processes. The process and the equipment thereof can solve the problem that the paper-making reconstituted tobacco is difficult to be independently shredded. Patent CN102178337A discloses an independent tobacco shred making process and equipment based on paper-making method reconstituted tobacco processing characteristics, and provides a new reconstituted tobacco shred making process and equipment aiming at the universality and the processing characteristics of paper-making method reconstituted tobacco incoming materials. Patent 201210126975.X discloses a cut tobacco drying machine based on the independent cut tobacco forming characteristic of paper-making process reconstituted tobacco and a cut tobacco drying control method thereof, aiming at controlling the cut tobacco drying process of the paper-making process after the paper-making process is independently cut, the low-strength processing mode can effectively maintain the physical characteristic and the chemical characteristic of the paper-making process reconstituted tobacco after the paper-making process reconstituted tobacco is independently cut, and the sensory characteristic is effectively improved.
The above patents mention the drying process involved in the separate shredding of reconstituted tobacco leaves by the paper-making process, but all suffer from the following disadvantages: firstly, when the temperature is lower, the drying efficiency is lower, for example, the drying temperature of patent 201210126975X is 55-65 ℃; patent CN102178337A only shows vaguely that drying reduces the water content, and does not show the drying temperature and drying efficiency. Secondly, when the temperature is higher, although the drying efficiency is improved (namely the moisture content of the tobacco shreds can easily meet the requirement), the high drying temperature evaporates oily substances such as smoke agents and the like contained in the tobacco shreds and spices and essences with various tastes at high temperature, and has negative influence on the retention of the aroma of the obtained non-combustible tobacco shreds and the improvement of the sensory quality.
In addition, the above patent does not solve the following problems: the obtained reconstituted tobacco shreds produced by the paper-making method must be blended with other tobacco shreds, and cannot be independently used as non-combustible tobacco shreds for circumferential heating. Secondly, the low-temperature cut tobacco dryer equipment and the control method which are needed aiming at the characteristic that the reconstituted tobacco is used for heating the non-burning cut tobacco in the circumferential direction independently are not involved. And thirdly, the drying efficiency and the drying effect (namely the maintenance of the smoke agent and the spice essence) of the tobacco shreds which are not combusted during heating can not be considered at the same time.
The utility model discloses solve above-mentioned problem and propose.
