Pulping and extracting process for regenerated tobacco leaves

The invention relates to a pulping and extracting process for regenerated tobacco leaves, in particular to a process for preparing the regenerated tobacco leaves by using low-quality and waste tobacco raw materials which cannot be directly applied to producing cigarette products and by using a paper-making process of presoaking, pulping and extracting and countercurrent pulp washing. The process comprises the following steps of: presoaking tobacco leaf flakes and tobacco stalks which serve as raw materials; and directly performing pulping and extraction, countercurrent pulp washing, concentration and pulp mixing on the soaked materials. Compared with the conventional production process, the process has the advantages of accelerating lixiviation of the tobacco raw materials and dissolution of tobacco extract, and saving two to three steps of extraction process, an extractor before pulping and a spiral shoving separation system (inclined and flat helix) so as to simplify a tobacco regenerating process and equipment operation and flow and enhance dissolution and separation of the tobacco extract. By the step of countercurrent pulp washing, the tobacco raw materials can be extracted at a low temperature and the soluble extract in the raw materials can be recovered; extraction yield and leach liquor quality of the regenerated tobacco leaves are improved; load of treating sewage during generated tobacco leaf production is greatly reduced; and environmental friendliness, low carbon and energy conservation of the generated tobacco leaf production are realized.
