Description

Technical Field

[0001] The utility model relates to the technical field of inulin material-liquid separation, in particular to a filtering and separating device for inulin production. Background Art

[0002] Inulin is obtained by enzymatic extraction of water-soluble polysaccharides from Jerusalem artichokes or their stems and leaves. The inulin production process involves multiple steps, including raw material processing, extraction, precipitation, and washing. Raw material processing involves initially cleaning, slicing, and drying the harvested Jerusalem artichokes, followed by pulverization to obtain the inulin raw material. Extraction involves mixing the inulin raw material with an appropriate amount of water and adding enzymes at a suitable temperature to promote the hydrolysis of the polysaccharides, resulting in the inulin liquid.

[0003] The extracted inulin liquid contains unwanted components such as solid particles, suspended matter, impurities, and proteins. The above substances may affect the taste, color, and stability of the inulin. In order to improve the purity and quality of the inulin, the inulin liquid needs to be filtered and separated. At present, the filtration and separation of inulin liquid is generally completed by mechanical equipment. For example, a Chinese patent with patent number CN215878351U discloses a liquid-liquid separation device for an inulin preparation process, which includes an equipment body, an upper cover movably mounted on the upper surface of the equipment body, a box door movably mounted on the front surface of the equipment body, a centrifugal module movably mounted inside the equipment body, a bearing embedded in the contact position between the centrifugal module and the equipment body, a collection box embedded in the front surface of the equipment body, and a base fixedly mounted on the lower surface of the equipment body. The equipment body includes an outer shell, an air inlet pipe, a placement hole, a discharge port, and a feed pipe. The air inlet pipe is fixedly mounted on one side surface of the outer shell, and the placement hole is fixedly mounted on the other side surface of the outer shell. The material-liquid separation device for inulin preparation process described in the utility model can facilitate the cleaning of the interior, and the plug-in upper cover also frees up operating space for equipment maintenance. The centrifugal module can also replace the traditional filter cloth filtration, saving the time required for separation.

[0004] Although the material-liquid separation device provided by the above patent can be used for the separation of material and liquid, due to its own structural limitations, for example, a collection box provided at the bottom of the main body of the equipment is used to collect the separated material and liquid, but the space of the collection box is limited. Therefore, the material and liquid in the collection box need to be cleaned regularly. This method is not conducive to the efficient batch production of inulin, because if it is used for the batch production of inulin, it is necessary to frequently stop the machine to clean the collection box; in addition, the centrifugal barrel of the material-liquid separation device provided by the above patent is provided with spiral blades, and the centrifugal barrel is not convenient to be removed from the outer casing. Therefore, the solid particles and impurities trapped by the centrifugal barrel are not convenient to be cleaned from the centrifugal barrel, and the accumulated impurities are very likely to clog the pores of the centrifugal barrel, affecting the subsequent separation and treatment of the material and liquid.

[0025] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0026] Example 1

[0027] As described in the background art, in the primary step of inulin production, the inulin extract needs to be filtered and separated to remove impurities, solid particles, and other substances in the inulin extract. However, the existing liquid-liquid separation devices mentioned in the background art are not well suited for efficient batch production of inulin extract and are not conducive to cleaning impurities trapped in the centrifuge. To address the above-mentioned problems, this embodiment provides a new liquid-liquid separation and filtration device. The specific technical solution is described below.

[0028] like Figure 1 、 Figure 4 As shown, the new material-liquid separation and filtration device includes a barrel 1, a barrel cover 4, a filtration and separation assembly 3, and an infusion assembly 2. The top of the barrel 1 is open, and an infusion tube 14 is provided at the bottom. The infusion tube 14 is provided with a valve body. The barrel cover 4 is detachably mounted on the top of the barrel 1. The infusion assembly 2 is supported on the barrel cover 4, with one end inserted into the inulin extract and the other end extending through the barrel cover 4 into the barrel 1. The filtration and separation assembly 3 includes a filter cartridge 31 and a motor 33. The filter cartridge 31 is disposed within the space formed by the barrel cover 4 and the barrel 1. The motor 33 is disposed above the barrel cover 4 and can control the rotation of the filter cartridge 31. One end of the infusion assembly 2, which passes through the barrel cover 4, is located directly above the filter cartridge 31. When filtering the inulin extract using this device, the inulin extract is transported to the barrel cover 4 through the infusion assembly 2 and falls into the filter cartridge 31. Simultaneously, the motor 33 operates to control the high-speed rotation of the filter cartridge 31, forcing the liquid out of the filter cartridge 31, into the barrel 1, and finally out of the infusion tube 14. This arrangement enables continuous filtration and separation of the inulin extract, changes the current situation where the machine needs to be shut down to clean the collection box, and improves the efficiency of batch inulin production.

[0029] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6As shown, in order to achieve high-speed rotation of the filter cartridge 31 and force solid-liquid separation and filtration, a central tube 42 is provided in the middle of the cartridge cover 4, and an annular top plate 35 is fixedly provided on the top of the filter cartridge 31. The annular top plate 35 is sleeved on the outer side of the support ring plate 32 by bolts, and a rotating shaft 34 is provided in the middle of the support ring plate 32. The rotating shaft 34 is provided with an upper and lower through-structure, and a connecting plate 36 is fixedly provided at the bottom. The connecting plate 36 is connected to the support ring plate 32 by bolts, and the support ring plate 32 is connected and sleeved on the central tube 42 through a bearing. The rotating shaft 34 is connected through the central tube 42 by a bearing, and the top is connected to the motor 33 through a belt, so that the rotating shaft 34 can be controlled to rotate by the operation of the motor 33. Since the lower end of the rotating shaft 34 is connected to the lower end of the support ring plate 32, the support ring plate 32 and the filter cartridge 31 are driven to rotate at a high speed. Because the diameter of the filter cartridge 31 is smaller than the diameter of the barrel 1 and the height is smaller than the height of the space inside the barrel 1, a gap is left between the filter cartridge 31 and the barrel 1. When the filter cartridge 31 rotates at high speed, the liquid is discharged through the pores in the side wall of the filter cartridge 31, hits the side wall of the barrel 1, and then falls along the side wall of the barrel 1 to the bottom of the barrel 1, and is finally discharged from the infusion tube 14 of the barrel 1. At the same time, impurities, solid particles, etc. that fall into the filter cartridge 31 are trapped in the filter cartridge 31. In order to achieve more efficient filtration, a filter membrane, ultrafiltration membrane, etc. can also be installed on the outside of the filter cartridge 31. The operation of the filter membrane and ultrafiltration membrane further improves the purity of the inulin liquid. Because the annular top plate 35 is fixedly connected to the support ring plate 32 by bolts, the filter cartridge 31 can be disassembled when needed.

[0030] like Figure 2 As shown, in order to achieve the cleaning of the filter cartridge 31, the cylinder body 1 includes a main body 11 and a closing plate 12. The closing plate 12 is hinged to one side of the main body 11 and connected to the other side by bolts. The main body 11 and the closing plate 12 are both configured as a 180° arc structure. A conical shell is fixedly provided at the bottom of the main body 11, and a sealing groove 13 is provided at the top of the conical shell. The central angle of the sealing groove 13 is 180°. A sealing plate adapted to the sealing groove 13 is provided at the lower end of the closing plate 12, and a sealing layer is provided on the contact surface between the closing plate 12 and the main body 11. When it is necessary to clean the filter cartridge 31, the staff rotates the bolt to release the restriction of the main body 11 and one side of the closing plate 12, and controls the closing plate 12 to rotate about the axis to expose the filter cartridge 31. After the filter cartridge 31 is exposed, the bolts connecting the annular top plate 35 and the supporting ring plate 32 are rotated to release the restriction of the filter cartridge 31, and the filter cartridge 31 can be taken out of the cylinder body 1, which provides convenience for cleaning the substances in the filter cartridge 31.

[0031] like Figure 3As shown, in order to stably install the cylinder cover 4 on the cylinder body 1, a stepped groove 41 is provided on the edge of the lower side of the cylinder cover 4, and a baffle 43 is fixedly provided on the side. The top of the main body 11 and the closing plate 12 extend into the stepped groove 41, and the baffle 43 is connected by bolts and is provided on the outside of the main body 11.

[0032] Example 2

[0033] like Figure 7 As shown, on the basis of Example 1, in order to realize the delivery of inulin extract, the infusion component 2 includes a liquid pump 23, a liquid inlet tube 22 and an output tube 24. The liquid inlet tube 22 and the output tube 24 are respectively arranged at the inlet end and the output end of the liquid pump 23. The end of the output tube 24 is arranged through the rotating shaft 34. The end of the liquid inlet tube 22 away from the liquid pump 23 is communicated with the filter tube 21. The filter tube 21 is inserted into the inulin extract to intercept larger solid substances and prevent larger solid substances from entering the liquid pump 23 with the liquid.

[0034] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
