Problems solved by technology

In this traditional leaf moistening process, the atomized water tends to form relatively small water droplets on the surface of the tobacco leaves, causing the moisture inside the tobacco leaves to be unable to move outward. The moisture distribution on the surface of the tobacco leaves is uneven, and the local moisture is too large, resulting in an increase ...

Embodiment 1

[0015] For the 2009 Yunnan Baoshan K326B3F tobacco leaves, the leaves were moistened by traditional technology and full steam, as follows:

[0016] Traditional process of leaf moistening: According to the medium tobacco leaf processing parameters stipulated in YC / T146-2001, the leaves are moistened by mixing soda and water.

[0017] Full steam leaf moistening: set the steam pressure to 0.8~1MPa; turn on the heat exchanger before feeding, preheat the leaf moistening cylinder to make the circulating hot air reach above 90°C, during the preheating process, it is forbidden to add steam into the leaf moistening cylinder , to prevent condensation and reduce the appearance of water stains. Yirun: Feed K326B3F tobacco leaves 20×10 3 kg, set the flow rate of incoming tobacco leaves to 11×10 3 kg, open the hot and wet steam valve to make the steam pressure reach 0.95-1MPa, increase the temperature and moisture content of the first-run tobacco leaves, so that the temperature reaches 56...

Embodiment 2

[0027] For the 2009 Lufu Xunhong Da C3F tobacco leaves, the leaves were moistened using traditional leaf conditioning techniques and full steam, as follows:

[0028] Traditional process of leaf moistening: according to the processing parameters of fine tobacco leaves stipulated in YC / T146-2001, the leaves are moistened by mixing soda and water.

[0029] Full-steam moistening: open the hot and humid steam valve to make the steam pressure reach 0.85-95MPa, increase the temperature and moisture content of the first moistening tobacco leaves, so that the temperature reaches 52-56°C and the moisture reaches 18%-20%; second moistening: According to the technical parameters specified in YC / T146-2001, open the front / rear steam valve, adjust the temperature of the second moistening to 52-56°C, and the moisture to 18%-19%. Control the circulating hot air in the range of 80-100°C to facilitate the further uniform infiltration of water. After 11 minutes, finish moistening the leaves.

Embodiment 3

[0039] Repeat Example 1, the 2009 Baoshan K326X3F tobacco leaves were moistened by traditional leaf moistening process and full steam respectively, wherein the full steam moistened leaves had the following differences: open the hot and wet steam valves to make the steam pressure reach 0.95~1MPa, increase The temperature and moisture content of the tobacco leaves are such that the temperature of the first-run tobacco leaves reaches 52-56°C, and the moisture reaches 18.5%-19.5%. The second moistening temperature is 56-62°C, and the moisture content is 19%-20%.

[0040] The evaluation of the quality of the red-roasted slices shows that compared with the traditional leaf moistening, the water-stained smoke in the 2009 Baoshan K326X3F finished tobacco slices after full-steam moistening and threshing and redrying is significantly reduced, and the rate of large and medium slices is increased by 1.23% %, the loss rate of large and medium slices before and after rebaking decreased by 1...

Abstract

The invention discloses a leaf wetting method for improving quality of redried tobacco sheets. The method comprises the following steps of: setting a vapor pressure value at 0.8-1 MPa, wherein circulating hot air reaches 80 DEG C; wetting leaves for the first time so as to ensure that the temperature of upper tobacco leaves reach 55-65 DEG C while the water content of the upper tobacco leaves reach 18-21%, the temperature of middle tobacco leaves reach 50-56 DEG C while the water content of the middle tobacco leaves reach 18-22%, and the temperature of lower tobacco leavers reach 50-58 DEG C while the water content of the lower tobacco leaves reach 18-20%; carrying out secondary wetting according to technological parameter requirements specified in YC/T146-2001; and adjusting water content and temperature for the secondary wetting. Compared with a traditional process, the leaf wetting method for improving the quality of the redried tobacco sheets, disclosed by the invention, has the advantages of increasing the rate of big and middle sheets in a finished product tobacco sheets by 1.23-1.83%, reducing the loss of the big and middle sheets before and after redrying by 1.08-2.44%, reducing the stalk proportion by 0.19-0.40% and obviously reducing water spots and flush tobaccos; the tobacco leaves have the advantages of bright and uniform color, increased oil content, rich elasticity and looser organization structure; and the tobacco sheets are obviously improved in the aspect of sensory quality index.

Description

technical field [0001] The invention belongs to the technical field of cigarette leaf threshing and redrying, and in particular relates to a leaf moistening method which can effectively improve the quality of redrying sheet tobacco. Background technique [0002] Leaf moistening is an important basic link in the process of threshing and redrying, which directly affects the quality and usability of finished redrying tobacco. At present, the method of moistening leaves in threshing and redrying mainly adopts the method of mixing steam and adding water, and it is carried out according to the process parameters of "Technical Specifications for Tobacco Leaf Threshing and Redrying" (YC / T146-2001). In this traditional leaf moistening process, the atomized water tends to form relatively small water droplets on the surface of the tobacco leaves, causing the moisture inside the tobacco leaves to be unable to move outward. The moisture distribution on the surface of the tobacco leaves i...
