Embodiment 1

[0028]Metal impurities in tobacco stems, tobacco powder and low-grade tobacco leaf raw materials are removed by iron removal equipment, non-metallic materials are removed by foreign matter removal machines, rot and mildew are removed manually, and the screened raw materials are washed and removed by water. Miscellaneous to get the raw material after pretreatment. The treated tobacco stems, tobacco leaves, tobacco powder and water are respectively subjected to countercurrent extraction at a ratio of 1:5. The extraction water temperature is 55°C, and the extraction is performed twice for 30 minutes each time. The extraction waste residue of tobacco stems is discharged, and the tobacco leaves, The leaching waste residue is recycled, and the solid phase is screened through a vibrating sieve to screen out the larger waste residue that is not suitable for papermaking in the solid phase, and the paper-like substrate is made through conventional beating and papermaking processes. The ...

Abstract

The invention relates to application of a membrane separation technique in a tobacco sheet producing process. The method comprises the following steps of carrying out preprocessing, digestion and screening on tobacco stems, tobacco powder and low-grade tobacco leaves, carrying out separation and purification on screened coarse liquid through a ceramic membrane separating device, protein, saccharides, pectin and other macromolecule substances in the coarse liquid are eliminated, carrying out further purification through an organic ultrafiltration membrane to obtain finer purified liquid, and carrying out the organic membrane and double-effect evaporation, concentration, coating and drying, wherein trapped liquid processed by a membrane technique is reused in the digestion process. The method is simple in separation process, low in energy consumption, free of pollution and capable of eliminating macromolecule protein and pectin and maintaining effective substances in tobacco, improves tobacco quality, reduces energy consumption and can create certain economic benefit.

Description

technical field [0001] The invention belongs to the technical field of tobacco sheet production by papermaking, and specifically relates to a process for improving the sensory quality of tobacco sheet by using membrane separation technology to process tobacco waste extracts such as tobacco stems, tobacco powder and low-grade tobacco leaves. Background technique [0002] The scientific name of tobacco sheet is reconstituted tobacco leaf, which refers to tobacco waste materials such as tobacco powder, tobacco stems, tobacco leaf fragments and some low-grade tobacco leaves in the cigarette processing process as raw materials, which are recombined and processed to meet the requirements of cigarette formula. Tobacco regenerated raw materials, tobacco flakes are blended with natural tobacco leaves in a certain proportion to make cigarettes, the significance of which is: on the one hand, it can maximize the use of tobacco leaf raw materials and save the cost of cigarettes; on the ot...
