Scattered-tobacco stacking low-humidity slow flue curing process for flue-curing tobacco bulk curing barn

Abstract

The invention discloses a scattered-tobacco stacking low-humidity slow flue curing process for a flue-curing tobacco bulk curing barn. The process comprises 9 stages of a preheating stage, a primary yellowing stage, a main yellowing stage, a withering stage, a primary stem changing stage, a main stem changing stage, a leaf half-drying stage, a leaf drying stage and a stem drying stage. Different from the traditional curing method, the process is characterized in that a centrifugal fan is used for replacing an axial flow fan to perform forced ventilation and moisture removing, and a low-humidity method is used throughout the curing process instead of relative-high-humidity curing of the traditional curing method; meanwhile, the withering stage is added after leaf yellowing, so that the tobacco leaf water content achieves an appropriate level, and tobacco leave color fixation is facilitated; the stem changing stage time is prolonged, so that the tobacco stem yellowing and the tobacco leaf dehydration color fixation are facilitated.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco preparation, and in particular relates to a dense barn baking process for storing tobacco in a stacking manner. Background technique [0002] In the production of flue-cured tobacco, curing is the last important link that determines the yield and quality of tobacco leaves. It is also the weakest link in China's tobacco leaf production, which directly affects the sustainable development of tobacco leaves in my country. But at present, the traditional weaving rod form is mainly used in the way of loading smoke, which has low efficiency and a small amount of smoke loading, and fails to fully reflect the advantages of intensive baking. In recent years, with the rising labor cost of flue-cured tobacco and labor difficulties, the cost of growing tobacco for tobacco farmers has been increasing, which has affected the benefits of tobacco planting for tobacco farmers. Traditional smoke loadin...

Problems solved by technology

[0004] The object of the present invention is to solve the problems existing in the prior art, overcome the deficiencies of the existing roasting process, and provide a roasting technique in which loose leaves are piled up and filled with smoke , pay special attention to the control of humidity on the moisture and tissue temperature of tobacco leaves, so as to inhibit the enzymatic browning reaction, prevent the problems of steaming and roasting tobacco leaves, and solve the problem of supporting the baking process of intensive barns where loose smoke is packed and smoke, and improve Tobacco Leaf Quality and Economic Benefit
