Abstract

The invention relates to a method for increasing the pulp retention rate of papermaking-process reconstituted tobaccos. According to the method, calcium carbonate is added to mixed pulp with a certain beating degree, the calcium carbonate and the mixed pulp are fully adsorbed to form a compound coated with sodium alginate, a larger flocculation body is formed, then surface modification and stabilization treatment are performed on the flocculation body with aluminum sulfate, modified calcium carbonate is mixed with pulp by the aid of a multi-element compound retention and drainage aid system, and then the reconstituted tobaccos are formed through papermaking, squeezing, coating, drying and cutting processing. With the adoption of the method, the bonding force of the modified calcium carbonate to the pulp is increased, the loss cannot occur easily, and retention rates of the modified calcium carbonate and the pulp in the reconstituted tobaccos are high.

Description

[0001] 【Technical field】 [0002] The invention belongs to tobacco processing technology, and relates to the field of reconstituted tobacco leaf production by papermaking method. It is a method of firstly using mixed slurry to absorb calcium carbonate to form a compound, then combining sodium alginate to coat and modify the compound, and finally using multiple retention aids A method for improving the pulp retention rate of reconstituted tobacco leaves by using a rate system. [0003] 【Background technique】 [0004] Reconstituted tobacco leaves are also known as reconstituted tobacco leaves, tobacco flakes, homogeneous tobacco leaves, etc. Foreign countries began to study the use of paper-making reconstituted tobacco leaves in the middle of the last century. The domestic paper-making reconstituted tobacco industry developed and started relatively late, but the development speed and technological progress were relatively fast. It has a strong functional role in enhancing flavor...
