Abstract
Description
本发明属于卷烟制造技术领域，具体涉及一种旋转式真空回潮设备及用于烟草物料的回潮方法。The invention belongs to the technical field of cigarette manufacturing, and in particular relates to a rotary vacuum rehumidification device and a rehumidification method for tobacco materials.
在卷烟制丝加工过程中，为提高片烟加工质量，常通过真空回潮机对片烟进行回潮处理，提高烟草物料的含水率和温度，去除烟草青杂气，使烟叶变柔软，便于后续加工。现有技术中，真空回潮技术通常采用静态回潮的方式对烟叶进行处理，通过分片机为将烟包拆分成3～5块具有一定厚度的烟块，将烟块装入回潮箱，由输送轨道将回潮箱运入真空回潮机内进行抽真空和喷射蒸汽处理。此回潮方式主要存在两方面的问题，一是回潮箱内的烟块难以完全回透，烟叶回透率通常在98.5％左右；二是整批烟草物料进入真空回潮机后，需等待真空回潮机完成抽真空、喷射蒸汽等耗时约1小时的处理后方可进入翻箱喂料机为后续加工供料，此真空回潮设备及加工方式属于间歇式生产，不能实现连续生产，导致卷烟制丝生产效率难以提高。In the process of cigarette shred processing, in order to improve the processing quality of tobacco slices, the tobacco slices are often tempered by a vacuum tempering machine to increase the moisture content and temperature of the tobacco material, remove the tobacco green impurities, make the tobacco leaves soft, and facilitate subsequent processing. In the prior art, the vacuum tempering technology usually uses a static tempering method to process tobacco leaves. The cigarette pack is split into 3 to 5 cigarette blocks with a certain thickness by a slicer, and the cigarette blocks are loaded into a tempering box. The tempering box is transported into the vacuum tempering machine by a conveyor track for vacuuming and steam injection. There are two main problems with this tempering method. First, it is difficult for the cigarette blocks in the tempering box to be completely tempered, and the permeability of tobacco leaves is usually around 98.5%; second, after the whole batch of tobacco materials enters the vacuum tempering machine, it is necessary to wait for the vacuum tempering machine to complete the vacuuming, steam injection and other treatments that take about 1 hour before entering the box feeder for subsequent processing. This vacuum tempering equipment and processing method belong to intermittent production and cannot achieve continuous production, resulting in difficulty in improving the production efficiency of cigarette shreds.
为解决上述问题提出本发明。The present invention has been proposed to solve the above-mentioned problems.

使用本发明的旋转式真空回潮设备用于烟草物料回潮的方法，包括如下步骤：The method for rehumidifying tobacco materials using the rotary vacuum rehumidification device of the present invention comprises the following steps:
人工或机械松散后烟叶从原料仓11通过陡角带12送入进料仓13，然后通过限量管14和电子秤15定量输送至往复式布料带21上，往复式布料带21将烟叶通过料斗口221均匀布撒在进料料斗中，再通过进料口22均匀进入第一扇形区1；After manual or mechanical loosening, tobacco leaves are sent from the raw material bin 11 to the feed bin 13 through the steep-angle belt 12, and then quantitatively transported to the reciprocating cloth belt 21 through the limiting tube 14 and the electronic scale 15. The reciprocating cloth belt 21 evenly spreads the tobacco leaves in the feed hopper through the hopper opening 221, and then evenly enters the first sector 1 through the feed opening 22;
旋转轴24进行逆时针步进式旋转，第一扇形区1内的烟叶在第二扇形区2、第三扇形区3、第四扇形区4和第五扇形区5被抽真空处理，烟叶同时在第三扇形区3和第五扇形区5被蒸湿处理；抽真空处理的时间、蒸湿处理温度和时间等可根据不同烟叶加工需求进行设置；当烟叶到达第六扇形区6位置时，回潮合格的烟叶因为重力作用通过出料口25和出料罩251落入出料料仓26中，然后被运输带27输送至后续工序加工；扇形区7、8、9、10为空载状态，既不抽真空也不喷射蒸汽；重复上述步骤，烟叶就被连续松散回潮处理；针步进式旋转每隔一定时间如144秒(时间可以根据工艺要求任意设定)逆时针步进旋转1个扇形区；The rotating shaft 24 rotates counterclockwise in a step-by-step manner, and the tobacco leaves in the first sector area 1 are vacuumed in the second sector area 2, the third sector area 3, the fourth sector area 4 and the fifth sector area 5, and the tobacco leaves are steamed in the third sector area 3 and the fifth sector area 5 at the same time; the time of vacuuming, the temperature and time of steaming, etc. can be set according to different tobacco leaf processing requirements; when the tobacco leaves reach the position of the sixth sector area 6, the tobacco leaves that have passed the moisture recovery pass through the discharge port 25 and the discharge cover 251 due to gravity and fall into the discharge bin 26, and then are transported to the subsequent process by the conveyor belt 27; the sector areas 7, 8, 9, and 10 are in an unloaded state, and neither vacuuming nor steam injection is performed; repeating the above steps, the tobacco leaves are continuously loosened and moisture recovered; the needle step-by-step rotation rotates one sector counterclockwise in a step-by-step manner at regular intervals such as 144 seconds (the time can be arbitrarily set according to the process requirements);
如果到达第六扇形区6的烟叶回潮不合格，进料口22和出料口25关闭，第六扇形区6的烟叶继续被旋转至第七扇形区7、第八扇形区8、第九扇形区9和第十扇形区10，并继续逆时针步进式旋转进行回潮处理。If the moisture reconditioning of the tobacco leaves arriving at the sixth sector zone 6 is unqualified, the feed port 22 and the discharge port 25 are closed, and the tobacco leaves in the sixth sector zone 6 continue to be rotated to the seventh sector zone 7, the eighth sector zone 8, the ninth sector zone 9 and the tenth sector zone 10, and continue to rotate counterclockwise in a stepwise manner for moisture reconditioning.
