Problems solved by technology

[0003] Tobacco leaves are processed with the technological process of the prior art. When the moisture content of the tobacco leaves is not less than 16% and the tobacco leaves have good toughness, generally no vacuum rehydration treatment is required.
At the same time, in order to pursue a higher rate of flake production, the leaf threshing and re-baking factories generally adopt the "low temperature and slow roasting" technology in the leaf re-baking section, which is not conducive to the evaporation of green miscellaneous gases and ammonia in the leaves with water. and escape; on the other hand, it is also difficult to kill some molds and insect eggs in the tobacco leaves, which is unfavorable to the long-term storage of the leaves
In order to solve the shortcomings of the existing technology, some enterprises also send the tobacco leaf raw materials that will enter the production line to the vacuum moisture resurfacing equipment that is not connected with the threshing and redrying production line for processing, which increases the labor intensity of tobacco leaf crushing and operators, and Greatly reduced production efficiency

Embodiment Construction

[0015] The process of the present invention is to first prepare tobacco leaf raw materials, and transport them offline to the moisture regaining room for pre-remoisture treatment, and then transport them to the threshing and redrying workshop to the production line for subsequent processing.

[0016] Figure 1 shows the basic process flow diagram of the present invention, Figure 2 and Figure 3 are flow diagrams with some optional processes added. As shown in Fig. 2 and Fig. 3, the tobacco leaves are manually selected on the tobacco conveying line A at the front, and the handles are manually sorted. If necessary, the handles are laid and tipped. Then, the tobacco leaves are put into the steel through the distributing cart B. In the turnover box 1, the turnover box is sent to the vacuum moisture regaining machine 3 along the conveying line 2. After the vacuum rehydration treatment, the steel turnover box filled with tobacco leaves is transported to the designated station and the toba...

Abstract

The present invention relates to a tobacco leaf on-line vacuum conditioning pretreatment process. Said process includes the following procedures: manually selecting raw material, placing the raw material into transfer box on the conveying line, feeding the transfer box into the vacuum conditioning machine connected on the conveying line along the conveying line to make vacuum conditioning treatment, then feeding the transfer box into box-turning machine, and feeding it into the feeding machine and sand-sieving device to make sand-sieving treatment, then feeding the tobacco leaf raw material into the following various procedures.

Description

Technical field [0001] The invention relates to the technical field of tobacco leaf threshing and redrying pretreatment technology. Background technique [0002] At present, my country's tobacco industry has fully adopted the pretreatment technology of tobacco leaf threshing and redrying. The main technological process of the pretreatment section of tobacco leaf threshing and redrying commonly used by various tobacco companies is basically: raw material preparation → use a box turning machine or manually send the tobacco raw materials into the conveyor line → primary moisturizing → sand screening → flow Control→secondary moisturizing→metal removal. According to the needs of customers, some optional processes can be added, such as: raw material preparation→tobacco leaf pre-moisture (optional process)→to use the box turning machine or manually send the tobacco raw materials Into the conveyor line (when using manual, the cigarettes can also be unwrapped and tipped) → feeder (optiona...
