In the thick slurry thin sheet preparation process, the moisture content of the mixture containing tobacco powder is 78%-82%, and the mixture has good fluidity and can be cast on the annular steel belt by its own gravity.

The discharge pipe 151 extends into the mixing tank 11 and is fixedly connected to the mixing tank 11. The smoke powder is output through the discharge pipe 151. The dispersion component 152 is used to break up the smoke powder and make it fly and settle when the smoke powder is output through the discharge pipe 151, so as to ensure the uniformity of mixing.

[0062] More specifically, the dispersing component 152 includes a dispersing drive member (an optional motor), a transmission shaft 1521 and a dispersing impeller 1522. The transmission shaft 1521 extends into the mixing tank 11 and is rotatably connected to the mixing tank 11.

The transmission shaft 1521 is distributed parallel to the discharge pipe 151. The dispersing impeller 1522 can extend to the bottom of the discharge pipe 151. When the smoke powder is output through the discharge pipe 151, the dispersing drive member can drive the transmission shaft 1521 to rotate to drive the dispersing impeller 1522 to rotate. The dispersing impeller 1522 is provided with a plurality of blades. When the dispersing impeller 1522 rotates, the plurality of blades can break up the smoke powder output through the discharge pipe 151 to make the smoke powder fly and settle.

[0063] Alternatively, if Figure 3 As shown, a stirring output component 23 is provided in the premixing tank 21, the buffer tank 5 conveys the viscous slurry into the premixing tank 21, and the water adding mechanism 22 conveys water into the premixing tank 21. The stirring output component 23 is used to premix the viscous slurry and water in the premixing tank 21 to form a coating slurry, and output the coating slurry to reduce the mixing time of the coating slurry in the finished product tank 3 and ensure uniform mixing.

[0064] Specifically, the stirring output component 23 includes a stirring container 231, a screw rod 232 and a stirring drive 233 (which can be selected as a motor).

The water adding mechanism 22 and the buffer tank 5 respectively transport water and viscous slurry to the stirring container 231, and the stirring driving member 233 drives the screw rod 232 to rotate to stir the water and viscous slurry to form a coating slurry. The rotation of the screw rod 232 can drive the coating slurry to be output through the outlet 2312, so as to achieve premixing of the viscous slurry and water. It can be understood that after the coating slurry is output through the outlet 2312, it enters the space between the premixing tank 21 and the stirring container 231, and is output through the premixing outlet 213 of the premixing tank 21.

[0065] Optionally, the outlet 2312 includes a plurality of waist-shaped holes circumferentially distributed on the side wall of the stirring container 231 , and when the spiral rod 232 rotates, it can drive the coating slurry to extrude through the waist-shaped holes, further improving the premixing effect.

[0068] Optionally, a plurality of finished product tanks 3 may be provided, and all of the plurality of finished product tanks 3 are connected to the premix discharge port 213 of the premix tank 21 to ensure continuous production.

[0069] Optionally, both the buffer tank 5 and the finished product tank 3 are provided with heaters, and heating by the heaters can keep the viscous slurry in the buffer tank 5 and the coating slurry in the finished product tank 3 at a set temperature (30°C±5°C).

[0070] In this embodiment, the forming device 4 includes a primary baking mechanism 41, a peeling mechanism 42, a secondary baking mechanism 43 and a winding mechanism 44 which are distributed in sequence. The coating slurry in the finished can 3 is cast on the annular steel belt of the primary baking mechanism 41 for primary baking, then peeled off by the peeling mechanism 42, and then transported to the annular steel belt or mesh belt of the secondary baking mechanism 43 for secondary baking and then output, and wound up by the winding mechanism 44.

[0071] like Figure 5As shown, the embodiment of the present invention further provides a method for preparing a thin slice by a thick slurry method, which is applied to the above-mentioned device for preparing a thin slice by a thick slurry method. The method for preparing a thin slice by a thick slurry method comprises the following steps:

[0072] S1, the feeding mechanism mixes the material and water in proportion and adds them into the mixing tank 11, and the first agitator stirs and mixes them to form a viscous slurry. The water content of the viscous slurry is 55%±5%. This step controls the water content of the viscous slurry at 55%±5%, so that the deposition and soaking swelling of the tobacco powder are slowed down when the viscous slurry is left standing for a long time.

[0073] S2, let the viscous slurry stand in the buffer tank 5 for a set time (30min-40min)

[0074] S3, adding the viscous slurry and water into the premixing tank 21 in proportion to premix to form a coating slurry, the water content of the coating slurry is 79%±5%. In this process, water is added to the viscous slurry online to achieve premixing with water;

[0075] S4, conveying the coating slurry in the premixing tank 21 to the finished product tank 3, and stirring and mixing by the second stirrer;

[0076] S5, conveying the coating slurry in the finished can 3 to the forming device 4, and the forming device 4 forms the coating slurry output from the finished can 3 into a sheet.

[0077] The thick slurry thin slice preparation method can effectively speed up the mixing speed, improve the mixing uniformity, slow down the soaking, swelling and deposition of tobacco powder in the viscous slurry, and improve the consistency of the thin slice thickness.

[0078] Furthermore, step S1 is specifically as follows:

[0079] S1-1, the first feeder 12 first mixes the smoke generating agent, adhesive and water in proportion and then adds them into the mixing tank 11. Preferably, the smoke generating agent and adhesive can be pre-mixed and then mixed with water, so that the smoke generating agent can form a protective layer on the surface of the adhesive, which can prevent the adhesive from agglomerating in water and achieve rapid swelling of the adhesive in water.

[0080] S1-2, the second feeder 13 mixes the plant fiber pulp and the dispersant and adds them into the mixing tank 11. The dispersant can promote the dispersion of the plant fiber pulp in water and avoid agglomeration of the plant fiber pulp.

[0081] S1-3, the third feeder 14 adds baking powder into the mixing tank 11.

[0082] S1-4, the fourth feeder 15 adds the tobacco powder into the mixing tank 11, and the first stirrer stirs and mixes the tobacco powder evenly.

[0083] By dissolving the adhesive in water first, the dissolution effect of the adhesive can be ensured, and the tobacco powder is added to the mixing tank 11 last to avoid the tobacco powder and water mixing time being too long. By adding baking powder, the viscous slurry can form a honeycomb structure, further slowing down the sedimentation of the viscous slurry when it is standing.
