Method for improving water absorbability of reconstituted tobacco substrates
A technology for reconstituted tobacco leaves and water absorption, which is applied in the fields of tobacco, tobacco preparation, and tobacco treatment. It can solve the problems of shortening the contact time, reducing the coating amount of reconstituted tobacco leaves, and affecting the output of reconstituted tobacco leaves, and achieves high water absorption.

Embodiment 1
[0013] Tobacco powder, tobacco stems, and shredded tobacco pieces are soaked in water as raw materials, the soluble and insoluble are extracted and separated, the insoluble tobacco fibers are beaten, and the base sheet is made by papermaking, and the soluble extract is concentrated , sprayed onto the substrate, and then prepared ammonium bicarbonate solution, and then evenly brushed the ammonium bicarbonate solution on both sides of the undried wet substrate according to 1%-10% of the absolute dry weight of the substrate. The brush-coated wet substrate was dried at 110°C until it was completely dry, and then cut to obtain the experimental sample substrate. The reconstituted tobacco leaf substrate that had not been treated with ammonium bicarbonate solution was used as a blank sample for comparison, and then according to GB / T 461.1-2002 standard was used to measure and compare the water absorption, and the comparison results are shown in Table 1.

Embodiment 2
[0018] Tobacco powder, tobacco stems, and shredded tobacco pieces are soaked in water as raw materials, the soluble and insoluble are extracted and separated, the insoluble tobacco fibers are beaten, and the base sheet is made by papermaking, and the soluble extract is concentrated , sprayed onto the substrate, and then prepare an ammonium carbonate solution, and then evenly brush the prepared solution on the front and back of the undried wet substrate according to 1%-10% of the absolute dry weight of the substrate. The treated wet substrate was dried at 110°C until it was completely dry, and then cut to obtain the experimental sample substrate. The reconstituted tobacco leaf substrate that had not been treated with ammonium carbonate solution was used as a blank sample for comparison, and then according to GB / T 461.1-2002 standard for water absorption measurement comparison, the comparison results are shown in Table 2.

Embodiment 3
[0023] Tobacco powder, tobacco stems, and shredded tobacco pieces are soaked in water as raw materials, the soluble and insoluble are extracted and separated, the insoluble tobacco fibers are beaten, and the base sheet is made by papermaking, and the soluble extract is concentrated , sprayed onto the substrate, and then prepare a potassium bicarbonate solution, and then evenly brush the prepared solution on the front and back of the undried wet substrate according to 1%-10% of the absolute dry weight of the substrate. The coated wet substrate is dried at 110°C until it is completely dry, and then cut to obtain the experimental sample substrate. The reconstituted tobacco leaf substrate that has not been treated with potassium bicarbonate solution is used as a blank sample for comparison, and then according to GB / T 461.1-2002 standard for water absorption measurement and comparison, the comparison results are shown in Table 3.
