Abstract

The invention relates to a method of increasing calcium carbonate retention in paper-making reconstituted tobacco. The method includes adding calcium carbonate into tobacco stem pulp of certain beating degree, enabling the calcium carbonate and the tobacco stem pulp to fully adsorb so as to form a compound, coating the compound with carboxymethyl cellulose to form large flocculation, subjecting the flocculation to surface modification and stability treatment with aluminum sulfate, mixing the modified calcium carbonate and the tobacco pulp by the aid of a multielement compound retention and drainage system, and performing paper making, pressing, coating, drying and slitting to obtain the reconstituted tobacco. The calcium carbonate modified by the method has higher ability to bind with the pulp, loss is rare, and the retention of the modified calcium carbonate in the reconstituted tobacco is high.

Description

[0001] 【Technical field】 [0002] The invention belongs to the tobacco processing technology, and relates to the production field of reconstituted tobacco leaves by a papermaking method. Retention aid system to improve the effective retention rate of calcium carbonate in papermaking reconstituted tobacco leaves. [0003] 【Background technique】 [0004] Reconstituted tobacco leaves are also called reconstituted tobacco leaves, tobacco sheets, homogenized tobacco leaves, etc. Foreign countries have been studying the use of paper-making reconstituted tobacco leaves since the middle of the last century. The domestic paper-making method of reconstituting tobacco leaves has developed and started relatively late, but the development speed and technological progress are both fast. It has a strong functional role in enhancing flavor and moisturizing, and highlighting the style characteristics of cigarette products. At present, paper-making reconstituted tobacco leaves have become an im...
