Abstract

The invention relates to a method for increasing retention rates of pulp of papermaking reconstituted tobacco. The method includes adding calcium carbonate into tobacco stem pulp with a certain beating degree and enabling the calcium carbonate and the tobacco stem pulp to be sufficiently adsorbed to form complexes; wrapping the complexes with sodium alginate to form large flocculation aggregates; carrying out surface modification and stability treatment on the flocculation aggregates by the aid of aluminum sulfate; mixing modified calcium carbonate and the tobacco pulp with each other by the aid of a multi-component compound retention and drainage system to obtain mixtures and then carrying out papermaking, squeezing, coating, drying and slitting processing on the mixtures to obtain the reconstituted tobacco. The method has the advantages that binding force of the modified calcium carbonate and the pulp can be enhanced, loss can be prevented, and the modified calcium carbonate and the pulp in the reconstituted tobacco are high in retention rate.

Description

【Technical field】 [0001] 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 tobacco stem 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 retention rate of pulp in reconstituted tobacco leaves by papermaking process by using a rate aid system. 【Background technique】 [0002] 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 ro...
