Problems solved by technology

[0003] In the production of reconstituted tobacco leaves by the papermaking method, many fine fibers and some macromolecular substances such as pectin contained in the extract itself are often brought into the extract after solid-liquid separation, which will reduce the coating rate and the sensory quality of the product, and Too high fiber will also have a certain degree of impact on equipment such as evaporators
Due to the various sources of raw materials, the fibers in the extract have different shapes, and the quality, length and width of the fine fibers are also different. difficulty

Embodiment 1

[0020] Papermaking reconstituted tobacco leaf coating solution purification system, such as figure 1 shown ( figure 1 Pumps and valves are omitted in ), including refined liquid feed tank, rectangular sieve, refined liquid transition tank, centrifuge, refined liquid storage tank, membrane purification device and concentrated liquid feed tank connected in sequence, the concentrated liquid The outlet of the feed tank is connected to the concentrated evaporator, the concentrated evaporator is connected to the blending tank, the blending tank is connected to the coating liquid on-site tank, the coating liquid on-site tank is connected to the coating machine, and the coating machine is vibrated with the rotary screen The sieve is connected, and the discharge port of the rotary screen vibrating screen is connected with the feed port of the coating liquid on-site tank. The rectangular sieve comprises a first rectangular sieve and a second rectangular sieve, the inlets of the first r...

Embodiment 2

[0022] The process for purifying the coating liquid of reconstituted tobacco leaves by the papermaking method comprises the following steps:

[0023] (1) Primary purification: The extract of reconstituted tobacco leaves by the papermaking method is extracted and collected into the refined liquid feeding tank, and then sent to the rectangular sieve for primary purification through the pipeline. From the inside to the outside, they are 120 mesh, 120 mesh, 100 mesh, and 100 mesh. After purification, the first-level purified extract is obtained, and its insoluble content is ≤0.6%;

[0024] (2) Secondary purification: the first-stage purification extract is collected in the refined liquid transition tank, and sent to the centrifuge for centrifugation through the pipeline. The flow rate of the first-stage purification extract into the centrifuge is controlled at 140 L / min, and the centrifuge speed is 2900 rpm / min, after purification, the secondary purification extract is obtained, a...

Abstract

The invention discloses a purification system and a purification process for the coating liquid of reconstituted tobacco leaves by papermaking method, which is divided into the purification and concentration of the extraction liquid, and the purification of the recycling of the coating liquid after deployment. The former uses a rectangular sieve, a centrifuge and a membrane purification device for multiple Step-by-step purification, rectangular sieve, centrifuge and membrane purification device are used to purify the insoluble matter with different physical characteristics in the extract liquid step by step, reducing the content of insoluble matter in the extract liquid to less than 0.02%; the rotary screen vibrating screen is used for recycling the coating liquid The purification in the process is mainly aimed at the purification of the paper wool of the substrate that is carried off in the coating liquid after sizing. The purification system and purification process of the present invention maximize the purification effect of each purification equipment, can continuously and efficiently remove fine fibers and some macromolecular substances in the reconstituted tobacco leaf extract and coating liquid, and ensure that the quality of the coating liquid is stable and pure , which improves the efficiency of purification and ensures the stability of the product.

Description

technical field [0001] The invention relates to the field of reconstituted tobacco leaves, in particular to a system for purifying the coating solution of reconstituted tobacco leaves by a papermaking method and a purification process thereof. Background technique [0002] Paper-making reconstituted tobacco leaves are made of waste materials such as tobacco stems, tobacco powder, and dust generated during cigarette processing. After soaking and extracting, the fibers and soluble substances are separated from solid to liquid, and the fibers are formed into substrates by papermaking. The extract is purified, concentrated, blended to become a coating liquid and coated on the substrate, dried and sliced ​​to become finished reconstituted tobacco leaves for use in cigarette production. The production of reconstituted tobacco leaves by papermaking method is a process of "turning waste into treasure", which can effectively save the cost of cigarette production, fully utilize tobacc...
