| titleOfInvention | Processing method of sandwich type functional tobacco sheet |
| abstract | The invention relates to a processing method of a sandwich type functional tobacco sheet, which comprises the following steps: step S1, adding a certain amount of leaching liquor A into the waste tobacco raw materials, and leaching for 3-5h at the temperature of 30-45 ℃; step S2: concentrating the leaching liquor A, carrying out fine extraction, adding a certain amount of spice, and uniformly mixing for later use; step S3: leaching residues and a certain amount of wood pulp raw materials, adding a certain amount of auxiliary agents, and pulping; step S4: adding certain papermaking filler and retention aid into the pulped pulp, forming two pieces of wet paper by a double-net former, adding functional materials between the two pieces of wet paper by a distributor, compounding the two pieces of wet paper, squeezing and drying to obtain a substrate; step S5: and (5) spraying the mixture C obtained in the step S2, and then drying and cutting to obtain the sandwich type functional tobacco sheet. The invention has the beneficial effects that: the effective components in the waste tobacco raw materials can be greatly reserved, utilized and extracted; in addition, the addition of the auxiliary agent in the pulping process can obviously promote pulping and improve pulping efficiency and effect. |
