Treatment process for manufacturing tobacco cut stems by tobacco stem

Abstract

The invention provides a treatment process for manufacturing tobacco cut stems by a tobacco stem, which comprises processes of stem washing, stem storing, cut stems cutting and cut stems swelling. The treatment process is characterized by comprising the following steps: carrying out enzymolysis on a tobacco stem raw material before the stem is washed; further washing the tobacco stem after the enzymolysis; filtering and concentrating stem washing liquid; adding carbonyl diamide and monoammonium phosphate into the stem washing liquid during the concentration to ensure that Maillard reaction is performed among the carbonyl diamide and the monoammonium phosphate, and reducing sugar and other micromolecular compounds; and finally, directly adding the concentrated feed liquid into swelled cut stems, or directly applying the filtered stem washing liquid to tobacco sheet manufacture by a rolling method. In the process, lignin and other compounds are subjected to enzymolysis through pretreatment by biological enzyme before the cut stems are prepared, so that macromolecular compounds which are not in favor of sensory quality in the tobacco stem are transformed; the chemical substances which are beneficial to the tobacco are extracted as much as possible by further stem washing and are added into the tobacco cut stems after the swelling process, so that the inherent original tobacco fragrance in the tobacco stem is retained as much as possible; and the concentrated liquid and extra feed liquid are added into the tobacco cut stems after the swelling process, so that fragrance loss in the swelling process is avoided.

Description

technical field [0001] The invention relates to a tobacco processing method, in particular to a treatment process for improving the sensory quality of shredded tobacco stems and reducing the discharge of sewage in the production process into shredded tobacco stems. Background technique [0002] Tobacco stems are an important component of tobacco leaves, and after separation of stem leaves, tobacco stems accounting for about 25% of the total weight of tobacco leaves can be obtained. The types of chemical components contained in tobacco stems are basically the same as those in tobacco leaves. The shredded tobacco stems prepared by the existing technology have almost no tobacco aroma after being processed by stem washing and expansion. When the blending amount of shredded tobacco stems in the formula is large, the aroma will be insufficient and the strength will be weak during the burning and smoking process. Strong irritation and heavy miscellaneous gas, especially woody gas,...

Problems solved by technology

However, the discharge of cleaning water has caused certain pollution to the environment, and the discharged 50-60°C stem washing liquid contains a large amount of tobacco beneficial substances such as reducing sugar and total plant alkaloids, resulting in the addition of a large amount of external feed liquid in the feeding process. Grooming, compensating and masking deficiencies in the sensory quality of cut stems

Chinese patent CN1631276A discloses "a chemical stem washing method" which involves using a chemical washing liquid instead of clean water in the stem washing process. Its disadvantage is that it cannot cause burnt gas in the shredded tobacco stems after burning. Starch, cellulose, lignin, protein, pectin and other difficult water-soluble macromolecular compounds decompose, and the discharge liquid has greater pollution to the environment. At the same time, the added chemical substances are also harmful to the workshop environment. will cause some pollution

[0004] Traditional shredded tobacco stems are added before the shredded tobacco stems are expanded. After drying and expanding at high temperature, the added liquid and the inherent beneficial substances of the tobacco stems volatilize.
