Problems solved by technology

Since tobacco is a herbaceous plant, its own fiber content is low, and there are many fine components after pulping, which are not easy to stay in the wire part, and the loss is large, resulting in large raw material input and low output, which can only achieve a product yield of 60-70%.
On the other hand, because the tobacco substance contains starch, protein, pectin and other components, it is easy to stick to the surface of the drying cylinder during drying, which affects the production efficiency; at the same time, the ratio of fiber pulp and tobacco pulp is poor in uniformity

Embodiment 1

[0023] 1. Independent pulp preparation: Tobacco pulp and fiber pulp are prepared separately,

[0024] Wherein, the weight configuration ratio of tobacco and water is 2.5%.

[0025] The weight configuration ratio of added fiber and water is 2.5%.

[0026] Heading: Send the configured tobacco pulp and additional fiber pulp into the double-layer headbox, and when the pulp is discharged from the double-layer headbox, in the formed slurry, the tobacco pulp is located in the upper layer, and the added wood pulp is located in the lower layer . When the pulp is discharged from the double-layer headbox, the flow rate ratio of the added wood pulp pulp and tobacco pulp is 1:5.

[0027] The specific parameters of the final product

[0028] 10% increase in tensile strength,

[0029] The fine fiber content in concentrated white water is less than 0.1%.

[0030] Product yield increased by 10%

Embodiment 2

[0032] 1. Independent pulp preparation: Tobacco pulp and fiber pulp are prepared separately,

[0033] Wherein, the weight configuration ratio of tobacco and water is 3%.

[0034] The weight configuration ratio of the added fiber and water is 3%.

[0035] Heading: Send the configured tobacco pulp and additional fiber pulp into the double-layer headbox, and when the pulp is discharged from the double-layer headbox, in the formed slurry, the tobacco pulp is located in the upper layer, and the added wood pulp is located in the lower layer . When the pulp is discharged from the double-layer headbox, the flow rate ratio of the added wood pulp pulp and tobacco pulp is 1:6.

[0036] The specific parameters of the final product

[0037] Tensile strength increased by 8.5%,

[0038] The fine fiber content in concentrated white water is less than 0.1%.

[0039] Product yield increased by 8.6%

[0041] 1. Independent pulp preparation: Tobacco pulp and fiber pulp are prepared separately,

[0042] Wherein, the weight configuration ratio of tobacco and water is 3.2%.

[0043] The weight configuration ratio of added fiber and water is 3.2%.

[0044] Heading: Send the configured tobacco pulp and additional fiber pulp into the double-layer headbox, and when the pulp is discharged from the double-layer headbox, in the formed slurry, the tobacco pulp is located in the upper layer, and the added wood pulp is located in the lower layer . When the pulp is discharged from the double-layer headbox, the flow rate ratio of the added wood pulp pulp and tobacco pulp is 1:7.

[0045] The specific parameters of the final product

[0046] Tensile strength increased by 8%,

[0047] The fine fiber content in concentrated white water is less than 0.1%.

[0048] Product yield increased by 8%.

Abstract

The invention relates to a double-layer papermaking process for paper-making reconstituted tobacco and equipment for the double-layer papermaking process. The double-layer papermaking process can reduce the waste of raw materials, particularly the waste of tobacco pulp. The double-layer papermaking process comprises the step of allowing pulp to enter a molding net for papermaking; and the double-layer papermaking process also comprises the steps of independently mixing the pulp and feeding the pulp before the papermaking step. The equipment comprises two sets of pulp mixing systems which are independent respectively, and a pre-net flowing delivery system, wherein a double-layer headbox comprises a headbox body; the top of the headbox body is provided with a feed port; a discharge port is formed below a side wall of the headbox; a partition plate is also arranged in the headbox body, and partitions the headbox body into two independent headboxes; the two headboxes are provided with homogenating rollers with power devices respectively; a baffle divides the discharge port into upper and lower layers; the headbox of which the discharge port is positioned on the upper layer is a tobacco pulp headbox; and the headbox of which the discharge port is positioned on the lower layer is an external fiber headbox. The double-layer papermaking process and the equipment have the advantages that the utilization rate of the tobacco pulp is improved, and the adhesion of substrates of reconstituted tobacco and the cylinder surface of a drying cylinder during drying is effectively prevented.

Description

technical field [0001] The invention relates to a double-layer papermaking process and equipment for reconstituted tobacco leaves by a papermaking method. Background technique [0002] At present, the existing papermaking method reconstituted tobacco leaves is to independently pulp the added fibers, tobacco stems and tobacco shredded leaves (there are also manufacturers who mix and pulp, that is, first mix in proportion and then make pulp), then blend in proportion and then copy it on the Internet. . Since tobacco is a herbaceous plant, its fiber content is low, and there are many fine components after pulping, which are not easy to stay in the wire part, and the loss is large, resulting in large raw material input and low output, which can only reach 60-70% product yield. On the other hand, because the tobacco material contains starch, protein, pectin and other components, it is easy to stick to the surface of the drying cylinder during drying, which affects the production...
