Description

Technical Field

[0001] This utility model relates to the field of sugarcane polyphenol extraction technology, and in particular to a multi-tower circulating extraction device for sugarcane polyphenols. Background Technology

[0002] A multi-tower polyphenol extraction device consists of a certain number of ion exchange towers, usually composed of 4 tower groups. Each tower group is composed of multiple exchange towers, and solid adsorbents such as resins (anion exchange resins or cation exchange resins) are filled inside the exchange towers. All exchange towers are fixed on a rotating turntable.

[0003] The water and materials used in polyphenol extraction are switched via a central control valve. This valve consists of two parts: a fixed upper section and a rotating lower section. The slots in the rotating section are connected to the fixed section and the turntable. The number of slots in the rotating section is the same as the number in the fixed section, and they are connected to the feed end of the tower group. When the slots in the rotating section of the central control valve align with the slots in the fixed section, material or water flows into the tower group. The turntable rotation and interval are preset before system operation. Based on the set time, the system rotates one station at a time, that is, the position of one tower group. Simultaneously, the slots on the rotating section also rotate one position, aligning them with the slots on the fixed section. During multi-tower extraction, each tower group undergoes a complete cycle when the turntable rotates one revolution: adsorption, washing, elution, and washing. Furthermore, additional steps can be added to the polyphenol extraction process depending on its complexity.

[0004] Each tower group requires a transfer pump for transport between its unit towers. This process consumes a lot of energy and generates noise, which affects the working environment. Utility Model Content

[0005] In order to overcome the defects of the prior art, this utility model provides a multi-tower circulating extraction device for sugarcane polyphenols to solve the problem of high energy consumption of the conveying pump.

[0006] The technical solution adopted by this utility model to solve its problem is: A multi-tower circulating extraction device for sugarcane polyphenols includes tower groups, a distribution valve, and a rotary table. Multiple tower groups are arranged on the rotary table, and the number of tower groups is an integer multiple of four. The feed end of each tower group is connected to the output end of the distribution valve for material transfer. Each tower group includes multiple unit towers connected by pipes. The discharge end of one unit tower is connected to the feed end of an adjacent unit tower via the pipe, allowing the multiple unit towers to be connected in series. The multiple unit towers are arranged in a stepped manner, with the unit towers closer to the distribution valve higher than those farther from the distribution valve.

[0007] Furthermore, the distribution valve includes a fixed part and a rotating part, the rotating part rotating relative to the fixed part. The fixed part is provided with an inlet pipe, a first water inlet pipe, an elution pipe and a second water inlet pipe, the inlet pipe, the first water inlet pipe, the elution pipe and the second water inlet pipe being evenly arranged circumferentially. The rotating part is provided with four outlet pipes, the four outlet pipes being evenly arranged circumferentially, the inlet pipe, the first water inlet pipe, the elution pipe and the second water inlet pipe corresponding one-to-one with the four outlet pipes.

[0008] Furthermore, sugarcane molasses is supplied to one of the discharge pipes on the rotating part through the inlet pipe on the fixed part, water is supplied to one of the discharge pipes on the rotating part through the first water inlet pipe on the fixed part, eluent is supplied to one of the discharge pipes on the rotating part through the elution pipe on the fixed part, and water is supplied to one of the discharge pipes on the rotating part through the second water inlet pipe on the fixed part.

[0009] Furthermore, the unit tower has a feed inlet at the upper end and a discharge outlet at the lower end. One discharge outlet at the lower end of the unit tower is connected to the feed inlet at the upper end of another adjacent unit tower via a pipe.

[0022] Example: refer to Figures 1-4 As shown, a multi-tower circulating extraction device for sugarcane polyphenols includes a tower group 2, a distribution valve 1, and a rotary table 3. The tower group 2 has multiple groups, each mounted on the rotary table 3. The number of tower groups 2 is an integer multiple of four. The feed end of each tower group 2 is connected to the output end of the distribution valve 1 for material transfer. Each tower group 2 includes multiple unit towers 21, which are connected together via pipes 22. The discharge end of one unit tower 21 is connected to the feed end of an adjacent unit tower 21 via the pipe 22, allowing the multiple unit towers 21 to be connected in series. The multiple unit towers 21 are arranged in a stepped manner, with the unit towers closer to the distribution valve 1 being higher than those farther away. This stepped arrangement gradually reduces the height between the multiple unit towers 21, enabling material transfer between them to be powered by pressure difference, eliminating the need for external force and resulting in low energy consumption.

[0023] Among them, unit tower 21 is filled with macroporous resin, which is used to adsorb polyphenols in sugarcane molasses liquid.

[0024] Among them, multiple tower groups 2 are arranged in a circular array, and the distribution valve 1 is located above the multiple tower groups 2 and in the middle of the multiple tower groups 2.

[0025] The distribution valve 1 includes a fixed part 11 and a rotating part 12. The rotating part 12 rotates relative to the fixed part 11. The fixed part 11 is provided with an inlet pipe 111, a first water inlet pipe 112, an elution pipe 113, and a second water inlet pipe 114. The inlet pipe 111, the first water inlet pipe 112, the elution pipe 113, and the second water inlet pipe 114 are evenly arranged circumferentially. The rotating part 12 is provided with four outlet pipes 121. The four outlet pipes 121 are evenly arranged circumferentially. The inlet pipe 111, the first water inlet pipe 112, the elution pipe 113, and the second water inlet pipe 114 are respectively connected to the four outlet pipes 121. Each of the discharge pipes 121 corresponds to a specific discharge pipe. Sugarcane molasses is supplied to one of the discharge pipes 121 on the rotating part 12 through the liquid inlet pipe 111 on the fixed part 11. Water is supplied to one of the discharge pipes 121 on the rotating part 12 through the first water inlet pipe 112 on the fixed part 11.

Water is supplied to one of the discharge pipes 121 on the rotating part 12 through the second water inlet pipe 114 on the fixed part 11.

[0026] In a further extension of this embodiment, the turntable 3 can rotate at the same speed as the rotating part 12, and the rotation frequency of the turntable 3 is the same as that of the rotating part 12, and they rotate at the same time.

[0027] The rotation axis of the rotating part 12 and the rotation axis of the turntable 3 are located on the same straight line.

[0028] The polyphenol extraction steps are as follows: Adsorption-washing-elution-washing.

[0029] The inlet pipe 111 is used to transfer sugarcane molasses liquid. At this time, the inlet pipe 111 is connected to the first outlet pipe 121, and the sugarcane molasses liquid enters into the inlet pipe 111. The inlet pipe 111 is connected to the first outlet pipe 121, so that the sugarcane molasses liquid enters into the first outlet pipe 121. The first outlet pipe 121 is connected to the first tower group 2, so that the sugarcane molasses liquid is transferred from the first outlet pipe 121 into the first tower group 2, so that the macroporous resin in the first tower group 2 adsorbs the polyphenols in the sugarcane molasses liquid. After the rotating part 12 rotates one station, the turntable 3 rotates one station synchronously. At this time, the liquid inlet pipe 111 is connected to the second discharge pipe 121, and the first water inlet pipe 112 is connected to the first discharge pipe 121.

The first water inlet pipe 112 is used to transport water. Water enters the first water inlet pipe 112 and is connected to the first discharge pipe 121, so that water enters the first discharge pipe 121 to clean the first discharge pipe 121. The first discharge pipe 121 is connected to the first tower group 2, so that water is transported from the first discharge pipe 121 into the first tower group 2 to clean the sugarcane molasses residue on the macroporous resin in the first tower group 2. After the rotating part 12 rotates one station again, the turntable 3 rotates one station synchronously. At this time, the liquid inlet pipe 111 is connected to the third discharge pipe 121, the first water inlet pipe 112 is connected to the second discharge pipe 121, and the elution pipe 113 is connected to the first discharge pipe 121. The sugarcane molasses solution enters the inlet pipe 111, which is connected to the third outlet pipe 121. The third outlet pipe 121 is connected to the third tower group 2, so that the sugarcane molasses solution is transferred from the third outlet pipe 121 into the third tower group 2, where the macroporous resin in the third tower group 2 adsorbs the polyphenols in the sugarcane molasses solution. Water enters the first inlet pipe 112, which is connected to the second outlet pipe 121, allowing water to enter the second outlet pipe 121 to clean it. The second outlet pipe 121 is connected to the second tower group 2, allowing water to be transferred from the second outlet pipe 121 into the second tower group 2 to clean the residual sugarcane molasses on the macroporous resin in the second tower group 2. The elution tube 113 is used to transfer the eluent. The eluent enters the elution tube 113 and is connected to the first discharge pipe 121, so that the eluent enters the first discharge pipe 121. The first discharge pipe 121 is connected to the first tower group 2, so that the eluent is transferred from the first discharge pipe 121 into the first tower group 2, so that the eluent desorbs the macroporous resin in the first tower group 2. After the rotating part 12 rotates one station again, the turntable 3 rotates one station synchronously. At this time, the liquid inlet pipe 111 is connected to the fourth discharge pipe 121, the first water inlet pipe 112 is connected to the third discharge pipe 121, the washing pipe 113 is connected to the second discharge pipe 121, and the second water inlet pipe 114 is connected to the first discharge pipe 121. The sugarcane molasses solution enters the inlet pipe 111, which is connected to the fourth outlet pipe 121. The fourth outlet pipe 121 is connected to the fourth tower group 2, allowing the sugarcane molasses solution to be transferred from the fourth outlet pipe 121 into the fourth tower group 2, where the macroporous resin in the fourth tower group 2 adsorbs the polyphenols in the sugarcane molasses solution. Water enters the first inlet pipe 112, which is connected to the third outlet pipe 121, allowing water to enter the third outlet pipe 121 and clean it. The third outlet pipe 121 is connected to the third tower group 2, allowing water to be transferred from the third outlet pipe 121 into the third tower group 2 to clean the residual sugarcane molasses on the macroporous resin in the third tower group 2. The eluent enters the eluent tube 113, which is connected to the second outlet tube 121, allowing the eluent to enter the second outlet tube 121. The second outlet tube 121 is connected to the second tower group 2, allowing the eluent to be transferred from the second outlet tube 121 into the second tower group 2, so that the eluent desorbs the macroporous resin in the second tower group 2. The second water inlet pipe 114 is used to transport water. Water enters the second water inlet pipe 114 and is connected to the first discharge pipe 121, so that water enters the first discharge pipe 121 to clean the first discharge pipe 121. The first discharge pipe 121 is connected to the first tower group 2, so that water is transported from the first discharge pipe 121 into the first tower group 2 to clean the eluent residue on the macroporous resin in the first tower group 2. The rotating part 12 and the turntable 3 continue to rotate, and sugarcane molasses liquid is transferred into the first tower group 2 through the liquid inlet pipe 111. The subsequent steps continue. The second tower group 2, the third tower group 2 and the fourth tower group 2 have the same process as the first tower group 2, so as to achieve continuous production without stopping the machine. All steps can be carried out simultaneously, improving production efficiency.

[0030] The unit tower 21 has a feed inlet 211 at the upper end and a discharge outlet 212 at the lower end. The discharge outlet 212 at the lower end of one unit tower 21 is connected to the feed inlet 211 at the upper end of another adjacent unit tower 21 through a pipe 22. The feed inlet 211 at the upper end of the unit tower 21 located at the first end is connected to one of the discharge pipes 121 through a connecting pipe 213. Multiple unit towers 21 are connected in series. Sugarcane molasses solution, eluent and water continuously pass through multiple unit towers 21, which can improve the utilization rate of sugarcane molasses solution, eluent and water, and improve the extraction rate of polyphenols.

[0031] The turntable 3 is provided with multiple descending steps 31, and multiple unit towers 21 are installed one by one on the multiple steps 31, so that one unit tower 21 is higher than another adjacent unit tower 21. When the liquid in one unit tower 21 is higher than that in another adjacent unit tower 21, the liquid in one unit tower 21 automatically flows to the other adjacent unit tower 21 through the pipe 22 through the pressure difference. Thus, the liquid can be transferred through the pressure difference without external force and with low energy consumption.

[0032] The pipeline 22 is equipped with an observation window 221, which allows the clarity of the water to be checked, thus ensuring that each unit tower 21 can be cleaned. At the same time, the observation window 221 can also be used to monitor the material flow status, promptly detect blockages or abnormal flow, and ensure continuous and stable operation. Through the series connection between each unit tower 21, polyphenols can be extracted step by step, resulting in high resource utilization and high production efficiency.

[0033] It should be noted that the principle of macroporous resin adsorption of polyphenols is as follows: macroporous resin has a three-dimensional network structure with specific pore sizes. When the size of sugarcane polyphenol molecules in sugarcane molasses matches the pore size of the resin, they can enter the pores, contact the functional groups, and interact with them to be adsorbed. Meanwhile, large molecular impurities (such as polysaccharides and proteins) are repelled because they are too large.

[0034] The eluent is an ethanol solution.

[0035] Elution involves releasing the polyphenols from the pores of the saturated macroporous resin (the resin that has been adsorbed with polyphenols).

[0036] It should be noted that the water is soft water.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
