Embodiment 1

[0093]After the wood pulp paddle board is crushed and defibrated into short fibers, it is stored in the storage tank. The length of a single fiber is 2-8mm. While removing the static electricity, the negative pressure generated by the vacuum box 28 makes the fibers form a fluffy, disorderly and staggered short thin layer on the forming wire 26 through the air-laid method. Then spray the glue to the surface of the substrate. When spraying, use the compressed air to fully atomize the liquid containing the adhesive, spray it on the surface of the substrate, and at the same time suck the negative pressure on the back of the sprayed surface. 2% of the mass (the mass ratio of the adhesive is: chitosan 70%, carboxymethyl starch 15%, cyclodextrin 10%, carboxymethyl cellulose 5%), the substrate sprayed with glue is transported to the oven Drying, and then spray glue on the other side using the same process as above. The amount of adhesive sprayed accounts for 2% of the weight of the dr...

Embodiment 2

[0095] After the bamboo pulp paddle is defibrated into single fibers, it is stored in a storage tank with a fiber length of 2 mm to 5 mm. 10% of tobacco powder (fragments) is mixed into the storage tank, and the metering air is sent to the forming head box 25. While the static electricity is removed by the antistatic rope 27 and / or the antistatic net 29, the negative pressure generated by the vacuum box 28 makes the fibers form a fluffy and disorderly staggered short fiber thin film on the forming net 26 through the air-laid method. layer, and then spray the glue. When spraying, use compressed air to fully atomize the glue and spray it on the surface of the substrate. At the same time, negative pressure is sucked on the back of the sprayed surface. % (the mass ratio of the adhesive is: chitosan 50%, pullulan starch 20%, dextrin 10%, carboxymethyl cellulose 5%, glucomannan 15%), substrates sprayed with glue Dry in an oven, then spray glue on the other side of the substrate. The...

Embodiment 3

[0097] After the wood pulp board is defibrated into single fibers, it is stored in the storage tank, and 10% short tobacco stem fibers and 10% tobacco powder (fragments) are added to the storage tank at the same time. The fiber length is 2mm-5mm, and the metering The wind is sent to the forming head box 25, and while the antistatic effect is removed by the antistatic rope 27 and / or antistatic net 29, the negative pressure generated by the vacuum box 28 makes the fibers form fluffy on the forming net 26 through the air-laid method. Disorderly stacked non-structural strength substrates, and then spray a composite adhesive material liquid mixed with a material liquid that improves the quality of paper-based absorption. When spraying, use compressed air to fully atomize the composite material liquid and spray it on the surface of the substrate. Negative pressure suction on the back of the sprayed surface, the spraying amount of the adhesive accounted for 3% of the weight of the dry...

Abstract

A method for manufacturing tobacco sheet taking substrate as a carrier through a dry paper making method comprises the following steps: spraying slurry onto the right side of the substrate through a high pressure spraying method, and meanwhile carrying out negative pressure suction across a wire belt to the reverse side of the substrate; then sending the substrate into an oven and carrying out medium temperature baking and humidity discharging under the condition that the temperature of the substrate is 55 DEG to 70 DEG, and enabling hot air inside the oven to flow directional from the right surface of the substrate to the reverse surface of the substrate to carry out humidity discharging; sequentially, carrying out normal temperature humidity discharging treatment; setting medium temperature baking and humidity discharging time and the normal temperature baking and humidity discharging alternatively; and repeating the steps on the reverse side of the substrate, namely a tobacco sheet is prepared. The substrate is prepared by that scattered material is evenly paved and absorbed onto a formation fabric for dry paper making to form a fiber thin layer under the vacuumpumping of a vacuum air pumping device under the formation fabric, and carrying out antistatic-electricity treatment; and spraying adhesion agent onto a fiber thin layer, under the combination of mist spraying and vacuum take-off on sprayed back surface; and finally carrying out drying.

Description

technical field [0001] The invention relates to a tobacco product and its processing technology, in particular to a new technology for manufacturing tobacco sheets with a base sheet manufactured by dry-laid papermaking technology as a carrier. Background technique [0002] Tobacco flakes are also known as reconstituted tobacco, reconstituted tobacco or homogenized tobacco. It is mainly composed of tobacco powder fragments, tobacco stems or low-grade tobacco leaves, plus plant fibers, adhesives and other additives. Reconstituted tobacco leaves have been widely used as cigarette products as raw materials for tobacco products. Sheets made of low-grade tobacco raw materials have the characteristics of low cost, good filling performance, and can reduce the tar content in smoke. The manufacture began in the 1950s. The manufacturing methods mainly include three methods: papermaking method, thick stock method and roller pressing method. Due to the relatively backward technology of...
