A kind of biomass fuel and a baking method for improving the smoking quality of Yunyan 87

Abstract

The invention discloses a biomass fuel and a baking method for improving the smoking quality of Yunyan 87. The biomass fuel is made by crushing straw under high pressure and medium temperature into granules, then adding mineral additives with 5-15% weight of straw granules and mixing evenly, and molding under the conditions of pressure of 50-100Mpa and temperature of 100-120°C , to obtain biomass fuel. The roasting method uses the aforementioned biomass fuel as the roasting fuel, and includes the steps of harvesting fresh leaves, preparing biomass fuel, furnace loading, controlling the yellowing period, controlling the color-fixing period, and controlling the dry gluten period. The biomass fuel of the present invention solves the environmental pollution caused by traditional coal burning and the problems of slow initial temperature rise and unstable combustion in the later stage during roasting. The content of starch and protein is significantly reduced, which effectively improves the aroma of tobacco leaves and the proportion of high-quality tobacco, and the sensory evaluation and smoking quality of tobacco leaves and economic benefits are significantly improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco curing, and in particular relates to a biomass fuel with low pollutant emission, quick temperature rise in the initial stage of curing, and stable combustion in the later stage, and a Yunyan 87 evaluation that can effectively improve the aroma of tobacco leaves and the proportion of high-quality tobacco Roasting method that sucks quality. Background technique [0002] The Yunyan 87 variety is bred by crossing Yunyan No. 2 as the female parent and K326 as the male parent. It was approved by the National New Variety Approval Committee in 2002 and is very suitable for planting in areas with an altitude of 1500-1800m. Although the cultivation history of Yunyan 87 is relatively short, its output is medium to high. After roasting, the tobacco leaves are golden in color, moderate in thickness, rich in oil, strong in luster, strong in smoke flavor and strong in strength. It is an ideal main tobacco leaf. ...

AI Technical Summary

Problems solved by technology

In recent years, with the expansion of the cultivation area of ​​Yunyan 87, due to the inadequacy of the baking equipment and supporting technology, the proportion of hanging ash and variegated smoke in the baking of Yunyan 87 is relatively high, which directly leads to a significant reduction in the income of tobacco farmers, and grass-roots tobacco production purchases Technicians and tobacco farmers are afraid of roasting, which affects the supply of high-quality raw materials and sustainable development of the cigarette industry

[0003] The traditional tobacco leaf baking is coal baking. Although it is convenient to obtain materials, it also has the problems of high pollution and high cost. In addition, in the tobacco leaf baking, the coal is ignited or the combustion is relatively lagging behind after adding materials. Compared with the biomass in the prior art The temperature of the fuel is 2-4 ℃ lower, which leads to a small heating rate in the early stage of yellowing, and different degrees of cured black and green smoke appear after the tobacco leaves are roasted; and when the coal is roasted and the air is sufficient, the later temperature will be lower. The rapid rise causes the temperature in the barn to fluctuate from high to low, and it is easy to cause the content of total sugar and reducing sugar in the tobacco leaves of Yunyan 87 to be low after curing, and at the same time, the content of nitrogen compounds such as total nitrogen, protein, and volatile alkali is high. As a result, the cured tobacco leaves are more miscellaneous and irritating, and have a greater impact on the aroma quality

[0004] In view of the problems existing in coal roasting, there are currently common biomass fuel roasting, electric roasting and natural gas roasting. It is a big problem, but due to the uneven texture, low calorific value and fragility of ordinary biomass fuel, there are also problems such as short burning time and difficult temperature stability control

In addition, although the temperature stability of electric roasting and natural gas roasting is easy to control, because tobacco leaf roasting is distributed in vast rural areas, electric roasting has the practical problems of high power supply expansion cost and difficulty in stabilizing power supply, while natural gas roasting has high fuel costs. , safety is difficult to guarantee and supply is difficult, so it can only be limited to some areas, and it is difficult to widely promote and apply
