Fecha de publicación: 03/01/2020 Fuente: WIPO "tobacco agriculture" The invention discloses a biomass fuel and a baking method for improving Yunyan87 smoking quality. The biomass fuel is prepared by crushing straws into granules under the conditions of high pressure and medium temperature, and then adding mineral additives accounting for 5-15% of the weight of the straw granules, uniformly mixing, and forming under the conditions that the pressure intensity is 50-100 Mpa and the temperature is 100-120 DEG C. The baking method takes the biomass fuel as baking fuel and comprises the steps of fresh leaf harvesting, biomass fuel preparation, furnace charging, yellowing period control, color fixing period control and stem drying period control. The biomass fuel disclosed by the invention solves the problems of environmental pollution of the traditional fire coal, slow temperature rise and unstable later combustion at initial stage in the baking process, and the baking method adopts the biomass fuel and the stage control, so that the starch and protein contents of the baked tobacco leaves are obviously reduced, the fragrance and the first-class tobacco ratio of the tobacco leaves are effectively improved, and the sensory smoking quality and the economicbenefit of the tobacco leaves are obviously improved.
