Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a pretreatment reactor for extracting soybean lecithin. Background Art

[0002] In the extraction of soybean lecithin, soybeans are first used as raw materials and pre-treated (such as peeling, crushing, etc.) to obtain soybean powder. Then the soybean powder and organic solvent (such as ethanol, acetone, etc.) are placed in a reactor and stirred at a certain temperature to fully dissolve the lecithin in the solvent. After the reaction mixture is discharged, centrifugal separation and drying steps are performed to obtain soybean lecithin powder.

[0003] In the above-mentioned mixed reaction of soybean powder and organic solvent, since there are many bean skins when the soybeans are crushed, it is difficult to fully filter them, or sufficient filtration requires cumbersome procedures that will increase processing costs. Therefore, the soybean powder contains bean skins, which affects the normal reaction and dissolution in the reactor. In addition, since the bean skins will exist at various height positions of the internal mixed liquid due to their own shape, the discharged liquid needs to be continuously filtered during the discharge process, which is quite unnecessary. At the same time, since the filtration requires a high-mesh filter, clogging problems are prone to occur, making the treatment of the mixed liquid quite inconvenient. Therefore, we propose a pretreatment reactor for soybean lecithin extraction. Summary of the invention

[0030] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0031] like Figure 1-Figure 10 A pretreatment reactor for soybean lecithin extraction shown in the figure comprises a reactor 1, a discharge portion is provided at the lower end of the reactor 1, a top cover 2 is fixedly installed at the upper end of the reactor 1, a rotating shaft 4 is rotatably connected to the lower surface of the top cover 2 through a driving mechanism, a driven shaft 15 is rotatably connected to the inner side of the reactor 1, the upper end of the driven shaft 15 is snap-fitted with the lower end of the rotating shaft 4, a stirring mechanism is provided on the outer side of the driven shaft 15, a sliding sleeve 5 is sleeved on the outer surface of the rotating shaft 4, a plurality of layer net mechanisms are provided on the outer surface of the sliding sleeve 5, and the layer net mechanisms are slidably matched with the inner wall of the reactor 1 along the vertical direction, a rotating net 30 is fixedly sleeved at the lower end of the outer surface of the rotating shaft 4, and a rotating plate 31 is fixedly embedded on the lower surface of the rotating net 30;

[0032] The layer net mechanism includes an inclined net 6, a vertical net 7 and a horizontal net 8 fixedly connected to the outer surface of the sliding sleeve 5. The upper and lower sides of the vertical net 7 are respectively fixedly connected to the inclined net 6 and the horizontal net 8. The edge of the horizontal net 8 is vertically connected with a retaining net 10; this part of the design can refer to Figure 5 , Figure 6 shown.

[0033] A feed port 25 is provided on one side of the upper surface of the top cover 2, and the layer net mechanism is offset from the bottom of the feed port 25, so that when the soybean powder is added, it will not fall directly on the surface of the layer net mechanism, thereby causing local accumulation and blockage of the layer net mechanism surface, and failing to ensure a sufficient mixing reaction. The cover plate can be rotatably installed at the port of the feed port 25, which is a common improved design and will not be described in detail.

[0034] like Figure 1 , Figure 2 As shown, the driving mechanism includes a motor 3 fixedly mounted on the upper surface of the top cover 2, the upper end of the rotating shaft 4 rotates through the upper surface of the top cover 2, and the upper end of the rotating shaft 4 is fixedly connected to the output shaft of the motor 3. The rotating shaft 4 is driven by the motor 3 to rotate.

[0035] like Figure 5 , Fig.10 As shown, the edges of the inclined net 6, the vertical net 7 and the horizontal net 8 close to the inner wall of the reactor 1 are fixedly connected with an arc plate 9, a slider 11 is convexly provided on one side surface of the arc plate 9, a slide groove 12 is provided on the upper end of the inner wall of the reactor 1, and the slider 11 slides and snaps into the inner side of the slide groove 12. This part of the design limits the snap-in position of the arc plate 9, plays a guiding role when the top cover 2 is installed, and can prevent the problem of synchronous rotation of the sliding sleeve 5 and the rotating shaft 4.

[0036] like Figure 3 , Figure 4 As shown, a lifting sleeve 14 is provided on the fixed sleeve on the outer surface of the rotating shaft 4, and a sliding sleeve 5 is provided on the outer surface of the rotating shaft 4, and the lower end of the sliding sleeve 5 slides against the upper end of the lifting sleeve 14 to ensure that the sliding sleeve 5 does not slide down excessively, and an extension net 13 is fixedly connected to the upper side of the blocking net 10, and the extension net 13 further increases the shielding range of the bean skin and improves the collection effect.

[0037] like Figure 8 , Fig.10 As shown, the stirring mechanism includes a plurality of connecting rods 16 fixedly connected to the outer surface of the driven shaft 15, the ends of the plurality of connecting rods 16 are commonly fixedly connected to a connecting ring 17, the outer surface of the connecting ring 17 is fixedly embedded with a stirring plate 18, and the lower end of the inner wall of the reactor 1 is fixedly connected to a lifting ring 19, the upper surface of the lifting ring 19 is rotatably matched with the lower surface of the connecting ring 17, so as to ensure that the connecting ring 17 can rotate relatively inside the reactor 1.

[0038] like Figure 7 , Figure 8 , Fig. 9 As shown, the upper end of the driven shaft 15 is fixedly connected to a chassis 20, a cross groove 21 is provided on the upper surface of the chassis 20, an inclined surface 22 is provided on the inner upper edge of the cross groove 21, the lower end of the rotating shaft 4 is fixedly connected to an upper plate 23, a cross block 24 is fixedly connected to the lower surface of the upper plate 23, and the cross block 24 is slidably inserted into the inner side of the cross groove 21. This design effectively reduces the difficulty of docking the rotating shaft 4 with the end of the driven shaft 15, and brings convenience to assembly and disassembly.

[0039] like Figure 3 , Fig.10 As shown, the edge of the top cover 2 is fixedly connected with an extension edge 26, the lower surface of the extension edge 26 is fixedly connected with an insert block 27, the upper end port of the reactor 1 is provided with a socket 28, and the insert block 27 is slidably inserted into the inner side of the socket 28. In order to prevent the top cover 2 from rotating during the mixing reaction, bolts can be installed on the surface of the extension edge 26 to reinforce it with the reactor 1 in order to ensure stability.

[0040] like Figure 1 As shown, the outer surface of the reactor 1 is provided with a bottom frame 33, the upper surface of the top cover 2 is fixedly provided with a hanger 32, and the discharge part includes a discharge port 29 fixedly embedded in the lower surface of the reactor 1, and a valve is provided at the end of the discharge port 29. When discharging, the valve is opened to discharge the mixed liquid from the discharge port 29.

[0041] The user adds an organic solvent (such as ethanol, acetone, etc.) from the feed port 25. After adding, ensure that the liquid level of the mixed liquid is higher than the uppermost layer net mechanism. When the motor 3 is running, the rotating shaft 4 and the driven shaft 15 rotate at the same time, and the rotating net 30 rotates synchronously. When the rotating plate 31 rotates, the liquid is stirred. Then, soybean powder is added from the feed port 25. During the adding process, when the rotating plate 31 rotates, the added powder is stirred and blended with the organic solvent. At the same time, the bean skin turns over with the rotation of the liquid, and part of the bean skin passes through the side of the inclined net 6 and reaches It then continues to flow and is blocked by the blocking net 10 and the extending net 13, and finally falls into the horizontal net 8 and is collected. Due to the inclined design of the inclined net 6 and the vertical design of the vertically connected net 7, the bean skin in the horizontal net 8 is better blocked to prevent the bean skin from overflowing after being turned over. With the continuous addition of bean powder, bean skin impurities will be above the horizontal net 8 of each layer and above the rotating net 30. Therefore, the problem of accumulation on the surface of the rotating net 30 will not occur, and the liquid will not be affected from flowing downward, and then it will be merged with a larger range of organic solvents to promote the dissolution of phospholipids.

[0042] When the user lifts the top cover 2, the rotating shaft 4 moves up, the upper plate 23 is separated from the bottom plate 20, the rotating net 30 also moves up synchronously, and the sliding sleeve 5 moves up synchronously under the support of the lifting sleeve 14, so that the layer net mechanism can be completely moved out to facilitate the later cleaning of the bean curd skin on the surface for reuse. When the top cover 2 is assembled back onto the reactor 1, the slider 11 is aligned with the slide groove 12 and inserted, and the insert block 27 is aligned with the socket 28 and inserted. The rotating shaft 4 can be slightly rotated during the docking of the cross block 24, so that the cross block 24 can slide into the inner side of the cross groove 21 under the push of the inclined surface 22, and the assembly can be completed. Therefore, disassembly, maintenance and later installation are convenient.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
