De-stem flue-cured tobacco one-step baking technique

Abstract

The invention relates to the processing way of baking tobacco without stalks by one time baking. Nowadays, most of the tobacco leaves are primarily baked by farmers before they are transferred to the tobacco re-baking factories to bake again and remove the stalks to provide materials for cigarette factories. There are several disadvantages in present technologies such as high cost, long processing time and low efficiency etc. The way mentioned in the invention can solve the previous problems. The procedures go as follows: remove the stalks of tobacco leaves; bake the tobacco leaves at low temperature until the water content of the tobacco leaves reduce to 2% or less; re-damping the tobacco leaves to the water content of 11-13%; the baked tobacco leaves can serve as the cigarette materials.

Description

Technical field: [0001] The invention relates to a production process method for once-cured destemmed flue-cured tobacco. Background technique: [0002] The existing tobacco leaf curing technology with stalks is that the farmers will pick the tobacco leaves with the same botanical characteristics from the field, manually bundle them on the poles and put them on the shelves, and fill them in the curing room before they can be cured. Roasting goes through three signature stages. That is, ① the yellowing period of tobacco leaves, ② the color fixing period of tobacco leaves, and ③ the dry tendon period of tobacco leaves. The temperature of the tendon drying period rises from the previous 55°C to 75-80°C, which lasts 20-30 hours. After the tobacco stems are completely dry and the farmers finish processing the entire tobacco leaf, the water content of the leaf is too low, which is easy to dry. If it is damaged, in order to carry out inspection and after-sales transportation, it ...

AI Technical Summary

Problems solved by technology

my country and other countries in the world have always been limited to equipment development and research in the field of flue-cured tobacco drying and processing, and have not made breakthroughs in production technology. Therefore, high efficiency and saving are a pair of opposites, and the desired effect has not been achieved. Farmers roast the leaves for the first time, and then deliver them to the commercial link for circulation. The tobacco leaves are transported to the re-curing processing plant of the tobacco company for the second roasting and destemming, and finally the industrial raw materials for cigarette factories can be produced.
