As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Example 1
Referring to fig. 1, the embodiment discloses a heating non-combustion reconstituted tobacco extraction device, which comprises at least one stage of extraction device 100. The extraction apparatus 100 comprises an extraction chamber 110, a screw shaft 120 and an ultrasonic generator 130, and has the advantages of simple structure, low cost, solvent saving, high extraction speed and high soluble substance extraction rate.
The extraction chamber 110 is a place where spraying, extraction and conveying processes occur, and has the advantage of an integrated structure compared with conventional extraction equipment, so that the field is saved, and pipeline conveying links among different parts are saved. Simultaneously, need not to adopt the pipeline to transmit the mixture and avoid setting up the delivery pump, reduce manufacturing cost and avoid stifled pipe risk. It is understood that the extraction chamber 110 is a cavity formed inside the support substrate, and the support substrate includes various spliced shell structures or integrally formed substrate structures with hollow-out interior.
The extraction chamber 110 has a cavity structure, and one end of the extraction chamber has a feed inlet 111, the feed inlet 111 is used for inputting tobacco raw materials, and the implementation manner of the extraction chamber can be a hopper type or the like. The other end of the extracting chamber 110 has a liquid outlet 112 and a pulp outlet 113, wherein the liquid outlet 112 is used for outputting extracting liquid (soluble substances), and the pulp outlet 113 is used for outputting tobacco residues (insoluble substances). It is understood that the outlet port 112 and the outlet port 113 are independent of each other.
Illustratively, the feed port 111 is provided with a spray end for spraying the solvent onto the tobacco material. In the spraying mode, the solvent is fully and uniformly contacted with the tobacco raw material, so that the solvent is greatly saved, the defect of excessive solvent consumption in the soaking mode is overcome, and the cost is correspondingly reduced; and the proportion of the solvent and the soluble substance is proper and not excessive and serious, so that the treatment difficulty of a subsequent treatment section is reduced. The spraying end can be realized by adopting a nozzle, a shower head or other spraying equipment, and the spraying mode can comprise automatic spraying and manual spraying.
Exemplarily, the liquid outlet 112 is provided with a filter screen to realize solid-liquid separation of the extracting solution and the tobacco residues, so as to sufficiently remove solid impurities in the extracting solution and further improve the purity of the extracting solution. The mesh number of the filter screen is determined according to actual needs so as to guarantee the purpose of filtering.
The screw shaft 120 is disposed in the extraction chamber 110 and is driven to rotate by a driving source. The driving source can be implemented in many ways, including a rotating electric machine 141, a hydraulic motor, and other driving devices capable of outputting circular motion. The driving source exemplarily includes a rotating motor 141 and a speed reducer 142, and the rotating motor 141 is connected to the screw shaft 120 through the speed reducer 142.
The screw shaft 120 has a spiral groove 121 on its surface for conveying and squeezing the material. Specifically, one end of the spiral groove 121 is in communication with the feed opening 111 to receive the tobacco material fed from the feed opening 111 and sprayed with the solvent. The other end of the spiral groove 121 is respectively communicated with the liquid outlet 112 and the pulp outlet 113 so as to correspondingly output the extracted extracting solution and the extracted tobacco residues, thereby preventing accumulation and congestion.
The space between the spiral groove 121 and the inner circumferential surface of the extracting chamber 110 is reduced from the feed port 111 to the liquid outlet 112, so that the tobacco material is gradually extruded in the advancing process to realize the extracting purpose. This reduction can be achieved in different ways, for example by changing the lead of the helical groove 121, changing the outer diameter of the helical groove 121, etc.
Exemplarily, the lead of the spiral groove 121 decreases from the inlet port 111 to the outlet port 112. In other words, the pitch of the spiral grooves 121 near the end of the feed port 111 is larger than the pitch of the spiral grooves 121 near the end of the discharge port 112. When the screw shaft 120 rotates, the helical groove 121 rotates accordingly to move the tobacco material along the axial direction of the screw shaft 120 from the inlet 111 to the outlet 112. In the advancing process of the tobacco raw material, the lead change of the spiral groove 121 gradually narrows the accommodating space of the spiral groove 121, so that the space between the spiral groove 121 and the inner circumferential surface of the extraction chamber 110 is gradually narrowed, the tobacco raw material is extruded by the extrusion effect to extrude the solvent with soluble substances in the cells of the tobacco raw material, the extraction purpose is realized, and the extraction efficiency is obviously improved. The lead, i.e. the pitch of the threads, refers to the axial distance between two points on the pitch diameter line of two adjacent teeth on the same spiral line.
Among them, the lead attenuation law of the spiral groove 121 is various. For example, the lead of the spiral groove 121 decreases from the inlet 111 to the outlet 112, forming a continuous attenuation law; for another example, the spiral groove 121 is composed of at least two groove segments, different groove segments have different lead lengths and form a stepwise attenuation law, and the lead lengths of the same groove segment are equal everywhere. Exemplarily, the lead ratio of the maximum lead to the minimum lead of the spiral groove 121 is not less than 2, and the attenuation rate is ensured so that the pressing action of the spiral groove 121 near the end of the liquid outlet 112 is more significant.
Illustratively, the inner diameter of the spiral groove 121 is constant throughout or increases from the inlet port 111 to the outlet port 112. Here, the space between the spiral groove 121 and the inner circumferential surface of the extracting chamber 110 gradually shrinks from the inlet port 111 to the outlet port 112 to ensure the squeezing and extracting action.
Illustratively, the axial direction of the screw shaft 120 is kept horizontal, and the liquid outlet 112 is located below the end of the screw shaft 120 away from the feed port 111. Accordingly, the extracted liquid extruded from the tobacco material drops to the liquid outlet 112 under the action of its own weight, thereby realizing liquid output. Illustratively, the outlet 113 is located at the end of the screw shaft 120 to recover tobacco residue extracted by extrusion. The recovered tobacco residue can be subjected to secondary extraction, and can also be subjected to subsequent process treatment to form a substrate.
Exemplarily, the screw shafts 120 are plural, and the plural screw shafts 120 are axially arranged in parallel in the extraction chamber 110 to form a multi-shaft conveying extrusion extraction structure, thereby further improving the extraction efficiency. It is understood that the plurality of screw shafts 120 can rotate in the same direction, or in opposite directions to form a counter-rotating relationship.
Exemplarily, the axial moving speed of the tobacco raw material on the screw shaft 120 is not more than 1.5m/min, so that the ultrasonic destruction action time and the extrusion extraction time of the tobacco raw material are sufficient, and the sufficient cell wall destruction and the ideal extraction rate are ensured. It is understood that the axial moving speed of the tobacco material depends on the rotation speed of the screw shaft 120 and the lead of the spiral groove 121, and is adjusted accordingly.
Illustratively, the wall thickness of the spiral groove 121 is not less than 0.5cm, which ensures the structural strength of the spiral groove 121 and prevents it from being broken or damaged by the reaction force of the tobacco material. Exemplarily, the length of the screw shaft 120 is not less than 5 m.
The ultrasonic generator 130 is used for emitting ultrasonic waves, and the ultrasonic waves act on the tobacco raw material in the spiral groove 121, so that cell walls of the tobacco raw material are effectively damaged, the diffusion of the solvent into the tobacco cells is accelerated, soluble substances are fully dissolved in the solvent, the diffusion and dissolution time is reduced, and the ultrasonic generator plays an important role in reducing the extraction time and improving the extraction rate of the soluble substances.
Illustratively, the ultrasonic generators 130 are plural, and the plural ultrasonic generators 130 are arranged in an array opposite to the spiral shaft 120 along the extending direction of the spiral shaft 120, so that the tobacco raw material is continuously subjected to the ultrasonic destruction during the conveying process. Exemplarily, the distance between adjacent ultrasonic generators 130 is 15-25 cm, and the ultrasonic generators have a better distribution density to form an ideal action coverage range, so that the tobacco raw material is sufficiently damaged.
The ultrasonic generator 130 may be installed outside the extraction chamber 110, for example, on a support substrate on which the extraction chamber 110 is located, and the installation position includes an outer circumferential side or both ends of the extraction chamber 110. Illustratively, the ultrasonic generator 130 is mounted in a position to ensure that its ultrasonic range of action covers the extraction chamber 110. For example, when the extraction chamber 110 is formed on a supporting substrate having a large wall thickness, the supporting substrate is correspondingly formed with a groove for installing the ultrasonic generator 130, thereby shortening the distance between the ultrasonic generator 130 and the extraction chamber 110.
Exemplarily, the frequency range of the ultrasonic generator 130 is 20 to 25kHz, so that the ultrasonic wave is kept in a low frequency range to obtain a more ideal ultrasonic destruction effect. Illustratively, the power of the ultrasonic generator 130 is not less than 500W, ensuring sufficient ultrasonic destruction power.
Exemplarily, the extraction device 100 further comprises a liquid receiving container 150 for receiving the extraction liquid. The receiving container 150 has an input end communicating with the extracting solution outlet 151, the input end communicates with the liquid outlet 112 to input the extracting solution, and the extracting solution outlet 151 is used for outputting the extracting solution for subsequent processes such as concentration. The liquid receiving container 150 may be of various types including a tray, a box, a tank, and the like.
Referring to fig. 1-2, when the extraction apparatus for reconstituted tobacco without burning has a multi-stage extraction device, a plurality of extraction devices 100 are connected in series to form a multi-stage distribution. Wherein, the pulp outlet 113 of the previous extraction device 100 is communicated with the feed inlet 111 of the next extraction device 100, so that the tobacco residue enters the next extraction device 100 for secondary extraction, thereby further improving the soluble substance extraction rate and reducing the material waste. Compared with the conventional extraction equipment, the extraction device 100 of the embodiment has a simple series connection mode, and is easy to realize multi-stage series connection. Wherein, the extraction device 100 of the previous stage is adjacently connected in series with the extraction device 100 of the next stage.
Illustratively, the pulp outlet 113 of the extraction device 100 of the previous stage is in open communication with the feed inlet 111 of the extraction device 100 of the next stage, for example, the transfer of tobacco residue is realized by an open slide way or a dead weight type blanking way.
Exemplarily, the liquid outlet 112 of the next-stage extraction device 100 is communicated with the feed inlet 111 of the previous-stage extraction device 100, so that the second-stage extraction liquid obtained by the next-stage extraction is used as the extraction solvent used by the previous-stage extraction device, thereby increasing the concentration of the extraction liquid, reducing the processing time of the subsequent concentration step, or eliminating the subsequent concentration step. The liquid outlet 112 of the extracting device 100 of the next stage is connected with the liquid inlet 111 of the extracting device 100 of the previous stage by a pump 200, and the conveying of the extracting solution is accelerated by pumping.
The technical effect of the equipment for extracting reconstituted tobacco without burning in the embodiment is further described below by combining comparative experimental data. In the comparative experiments, the solvent was chosen to be water.
The standard group of applied equipment for extracting the reconstituted tobacco without burning is provided with three-stage extraction devices which are connected in series in sequence. The indices of the extraction device 100 at each stage are: the screw shaft 120 is axially horizontal, the length of the screw shaft 120 is 10m, the lead ratio of the maximum lead position to the minimum lead position of the spiral groove 121 is 3, the axial moving speed of the tobacco raw material on the screw shaft 120 is 1m/min, and the tobacco flux of the spiral groove 121 is 500 kg/min; the ultrasonic generators 130 are arranged at the bottom of the extraction chamber 110 in a horizontal direction in an array, the distance between adjacent ultrasonic generators 130 is 15cm, and the power of a single ultrasonic generator 130 is 650W.
The extraction equipment of the control group was a conical soaking tank with a capacity of 25m combined with a twin-roll squeezer3The temperature of the heat-preservation jacket is 60 ℃, the flux of the double-roller pulp extruder is 500kg/min, and the pulp dryness is 34%.
The extraction processes of the standard group and the control group are three-stage countercurrent extraction, and the mass of the tobacco raw material is 2900 kg. Comparative experimental data are shown in the following table. As shown in the table, the standard group was significantly superior to the control group in terms of extraction time, amount of extraction solvent and extraction rate. Meanwhile, when the three-stage countercurrent extraction is carried out, the standard group only needs to use three-stage extraction devices (namely three extraction devices 100), while the contrast group needs to use six extraction devices, so that the difference of the equipment cost is obvious. Meanwhile, the standard group only needs to use electric power, and the control group also needs to use hot water or steam.
