Threshing and redrying preprocessing technology for burnt hairy tobacco

Abstract

The invention discloses a threshing and redrying preprocessing technology for burnt hairy tobacco, which is characterized by comprising the following steps: removing the overwrap of a whole packet of burnt hairy tobacco, and feeding in a hot water soakage machine for soaking into a soaked tobacco packet; placing the soaked tobacco packet in a tunnel type net belt conveyor introduced with steam to be fed into the next procedure, warming and humidifying the tunnel type net belt conveyor, and enabling the tobacco packet to be a loose tobacco packet when the tobacoo packet reaches the outlet of the tunnel type net belt conveyor; and loosening the bundles of the loose tobacco packet artificially, removing impurities thereof, conveying the tobacco packet to a bundle platform, and pouring the tobacco packet in the subsequent procedures of threshing and stalk removing. The loose tobacco packet obtained by the technology of the invention eliminates the hardened phenomenon of the tobacco packet, realizes the subsequent mechanical threshing and stalk removing processing of the burnt hairy tobacco in a large scale, meets the industrialized production requirement of cigarettes.

Description

technical field [0001] The invention relates to a production process of fuzzy tobacco, more specifically a pretreatment process for threshing and re-roasting of fuzzy tobacco, including steps such as remoisturizing, loosening and increasing the temperature and humidity of leaves in the process of threshing and redrying of fuzzy tobacco. Background technique [0002] As the main raw material for cigars, fuzzy tobacco has a long history. However, due to its unique paste rice water fermentation process, it is impossible to realize mechanized destemming. For a long time, the paste tobacco leaves are not destemmed or manually destemmed before being used in the formula. This traditional treatment process greatly limits the use range of the paste tobacco leaves, and also restricts the improvement of the quality of cigars. The reason for this status quo is mainly that the flakes shrink and harden after fermentation and packaging of the fuzzy tobacco, making it difficult to loosen a...

However, due to its unique paste rice water fermentation process, it is impossible to realize mechanized destemming

For a long time, the paste tobacco leaves are not destemmed or manually destemmed before being used in the formula. This traditional treatment process greatly limits the use range of paste tobacco leaves, and also restricts the improvement of the quality of cigars.

The main reason for this situation is that after the paste tobacco is fermented and packaged, the tobacco sheet shrinks and hardens, making it difficult to loosen and even more difficult to stretch.

[0003] Although at present, some tobacco factories use manual bagging first, then water on the tobacco leaves, and then carry out vacuum moisture resurgence treatment after placing to balance the moisture, so that the tobacco sheets are loose, which is suitable for leaf thresher destem processing, but this kind of watering On the one hand, it is difficult to water the tobacco handle thoroughly, and it is easy to produce uneven moisture, and it will produce a large amount of brown sewage; on the other hand, when the tobacco leaves are dry, they are forced to be manually unpacked and transported, and the tobacco leaves are seriously broken, which consumes a lot of labor. Large and expensive to produce
