Problems solved by technology

[0004] However, in the current extraction process, the water retention value of the soaked tobacco stems, shredded tobacco pieces, and tobacco dust in the extraction tank is relatively high, about 250% to 300% (w / w / ), and the water retention values ​​are successively separated by screw conveyor, water filter, etc. Spiral and screw squeezer processing can easily cause problems such as uneven and unstable discharge, low extraction rate of the extract, low purity of the solid phase, and difficult equipment cleaning, which further leads to poor sensory quality of the prepared tobacco sheet

Embodiment 1

[0109] Extraction device for reconstituted tobacco leaves by papermaking method, including primary extraction tank, screw conveyor, primary screw pump, primary screw discharge centrifuge, secondary extraction tank, secondary screw pump, secondary screw discharge centrifuge , Three-stage extraction tank, three-stage screw pump, three-stage screw discharge centrifuge and thickening tank.

[0110] in:

[0111] Such as figure 1 As shown, the first-stage extraction tank is an inclined horizontal drum extraction tank, which includes a tank body 1-1, a driving mechanism 1-2 and a bracket 1-3; the driving mechanism 1-2 is connected with the bracket 1-3, and the tank body 1- 1 Inclined on the support 1-3 and connected with the support 1-3 through the drive mechanism 1-2; the drive mechanism 1-2 drives the tank body 1-1 to rotate around its own central axis; the inner wall of the tank body 1-1 is connected There is a deflector, and the deflector is arranged in a spiral shape around th...

Embodiment 2

[0123] The technological process that adopts embodiment 1 extraction device to extract is as Figure 8 shown, including:

[0124] (1) Put the broken tobacco pieces (the broken tobacco pieces of flue-cured tobacco produced in Fujian) and 60°C hot water in a weight ratio of 1:6 into the primary extraction tank, and roll at a constant temperature of 60°C for 20 minutes to obtain a mixture;

[0125] (2) The mixture obtained in step (1) is quickly unloaded into the screw conveyor, and the screw conveyor is 15m 3 The flow rate of / h sends the material into the first-stage screw pump;

[0126] (3) The first stage screw pump is 15m 3 The flow rate of / h sends the material into the first-stage screw discharge centrifuge for solid-liquid separation, and the centrifugal speed is 2700r / min to obtain liquid phase and solid phase. Wherein, the solid content in the feed of the first-stage screw discharge centrifuge is 14% to 15% (w / w), and the water content of the obtained solid phase is ...

Abstract

The invention belongs to the field of paper-making reconstituted tobacco, and particularly relates to an extraction device used for the paper-making reconstituted tobacco. The extraction device comprises a first-stage extraction tank, a screw conveyer, a first-stage screw pump, a first-stage spiral discharge centrifugal machine, a second-stage extraction tank, a second-stage screw pump, a second-stage spiral discharge centrifugal machine, a third-stage extraction tank, a third-stage screw pump and a third-stage spiral discharge centrifugal machine. The invention further relates to a technologyfor preparing the reconstituted tobacco through a paper-making method. According to the extraction device and the preparation technology, the tobacco is uniformly and stably discharged, the extraction rate is high, the purity degree of the obtained solid-phase material is high, and the prepared tobacco sheets are high in sensory quality.

Description

technical field [0001] The invention belongs to the field of reconstituted tobacco leaves by papermaking method, in particular relates to an extraction device for reconstituted tobacco leaves by papermaking method, and also relates to a process for preparing reconstituted tobacco leaves by papermaking method. Background technique [0002] The papermaking process of reconstituted tobacco leaves is made from tobacco waste (such as waste or low-grade tobacco stems, shredded tobacco flakes, and tobacco powder) through extraction, pulping, papermaking, coating and drying processes. Technology for reconstituted tobacco leaves (also known as tobacco flakes). [0003] In the current papermaking reconstituted tobacco leaf technology, the extraction process generally involves three-stage continuous countercurrent extraction of tobacco waste to obtain an extract for making a coating solution and a solid phase for subsequent pulping. The extraction device is usually composed of an extr...
