Abstract

The invention provides a preparation process of expanded stem products and belongs to the technical field of tobaccos. The preparation process comprises the following steps of: removing impurities such as metal, hemp ropes, stem heads and stem picks in tobacco stems; expanding the tobacco stems by microwave and steam; conveying the expanded tobacco stems into a pressure container to carry out pressure treatment; carrying out moisture regaining on the tobacco stems after pressure treatment and preparing into a certain product form; adopting a soaking mode to wash the stems, then dewatering by a physical mode till the water content is below 70%, and then adding additive feed liquid extracted from the tobaccos; adopting the traditional equipment in the tobacco industry to dry the stem products added with the feed liquid till the water content is 11 to 12%, adopting a flavoring machine to carry out flavoring treatment on the dried stem products, and balancing the water content to 11 to 12%. The preparation process provided by the invention has the advantages that the whole process is simple, the energy consumption is low, the quality of the expanded stem products obtained is close to that of the shredded tobacco product, the filling value is high, and large-scale adding can be achieved, so that the expanded stem product is an excellent tobacco additive.

Description

technical field [0001] The invention relates to a process for preparing expanded stem products, in particular to a process for preparing high-quality microwave expanded tobacco stem products, and belongs to the technical field of tobacco. Background technique [0002] Tobacco stem is a by-product of the tobacco industry. It is the thick and hard veins of tobacco leaves, accounting for about 25% to 30% of the leaf weight. It is mainly used in the production of tobacco flakes and traditional shredded stems. At present, the tobacco stems can be puffed by microwave heating, and then the puffed tobacco stems can be mechanically processed into granules, strips, etc., and then added to cigarettes as tobacco additives. With the development of technology With continuous development, the quality of expanded tobacco stem products has been continuously improved, and the addition ratio in cigarettes can reach 20%. [0003] With the increase of the addition ratio, the influence of the in...
