Description

Technical Field

[0001] This application relates to the field of carrageenan purification technology, and in particular to a high-efficiency carrageenan purification apparatus. Background Technology

[0002] Carrageenan is a natural polysaccharide extracted from marine red algae. It has unique gelling properties and thickening effects, and is widely used in many industries such as food, medicine, and daily chemicals. In the food industry, carrageenan is often used as a stabilizer, thickener, and gelling agent, which can significantly improve the texture and taste of products. Due to its good biocompatibility and safety, carrageenan is also highly favored in the pharmaceutical field and is often used to make capsule shells and ointment bases. In addition, carrageenan also has important applications in daily chemical products, such as as a thickener and stabilizer in shampoos and shower gels.

[0003] Currently, the main method for purifying carrageenan is alcohol purification. Generally, a stirred tank is used to mix the filtered hot carrageenan solution with a hot alcohol solution, taking advantage of the low solubility of carrageenan in alcohol to achieve separation and purification.

[0004] Regarding the aforementioned technologies, existing carrageenan purification processes have numerous drawbacks in practical operation. First, during the purification process, carrageenan precipitates in a flocculent form. These flocculents easily entangle on the blades of the mixing tank. This entanglement not only interferes with the normal stirring process, leading to uneven mixing and affecting the purification effect, but also requires a significant amount of manpower and time to remove the carrageenan flocculents entangled on the blades during subsequent equipment cleaning, greatly reducing production efficiency. Second, after mixing alcohol with the carrageenan solution, the alcohol cannot be quickly separated from the mixture, resulting in a large amount of alcohol remaining in the purified material. This not only wastes alcohol and increases production costs, but the residual alcohol may also adversely affect subsequent product processing and use, causing many inconveniences. Utility Model Content

[0005] The purpose of this application is to provide a highly efficient carrageenan purification device, which has the advantages of easy cleaning and rapid separation, and solves the problems mentioned in the background art.

[0006] This application provides a high-efficiency carrageenan purification device with the following technical solution: It includes a support platform, with a first support frame and a second support frame fixedly connected to the top of the support platform. A steam tank is fixedly connected inside the first support frame, and a reflux tank is fixedly connected inside the second support frame. An inlet pipe and a third receiving pipe are fixedly connected to one side surface of the steam tank. A third flange is fixedly connected to the surface of the inlet pipe. A first conveying pipe is fixedly connected to the top surface of the steam tank. A first receiving pipe is fixedly installed at one end of the first conveying pipe via the first flange. A cyclone separator is fixedly installed on the surface of the first receiving pipe. A sealing plug is snapped into the top of the cyclone separator. A filter tube is threadedly connected to the bottom of the cyclone separator. A first filter screen is fixedly connected inside the filter tube. A solenoid valve is fixedly installed on the surface of the filter tube. A second conveying pipe is fixedly connected to the surface of the cyclone separator. A second receiving pipe is fixedly installed at one end of the second conveying pipe via the second flange. The second receiving pipe is fixedly connected inside the reflux tank. A reflux pipe is fixedly connected to the surface of the reflux tank. One end of the reflux pipe is fixedly installed on the surface of the third receiving pipe via a fourth flange. A storage cylinder is placed on top of the support platform. A first receiving ring is fixedly connected inside the storage cylinder. A first fixing ring overlaps the top of the first receiving ring. A filter cloth is fixedly connected inside the first fixing ring. Two handles are fixedly connected to the top of the first fixing ring. The filter tube is located at the top of the storage cylinder. By adopting the above technical solution and setting up a cyclone separator, hot carrageenan is filled into the cyclone separator during the purification process. Then, hot alcohol vapor is used for rapid purification. Subsequently, the inside of the cyclone separator is kept at a suitable temperature. Under this temperature condition, on the one hand, the solubility of alcohol in carrageenan is effectively reduced, allowing alcohol vapor to be quickly separated from the mixture, reducing alcohol residue in the purified material, avoiding alcohol waste, lowering production costs, and solving the adverse effects of residual alcohol on subsequent product processing and use. On the other hand, through solid-liquid contact, rapid separation and purification of carrageenan can be achieved. Moreover, no stirring device is installed during the entire purification process, which avoids the situation where carrageenan precipitates in flocculent form and wraps around the blades of the stirring tank. This not only ensures the normal operation of the stirring process and guarantees the purification effect, but also eliminates the need to spend a lot of manpower and time to remove the carrageenan flocculent material wrapped around the blades during subsequent equipment cleaning, greatly improving production efficiency. In addition, the alcohol vapor separated from the cyclone separator can be recycled and reused, saving costs. The filter tube is located at the top of the storage tank. The precipitated carrageenan is initially filtered through the first filter screen in the filter tube. After filtration, the carrageenan falls onto the filter cloth in the storage tank for solid-liquid separation. In practice, hot alcohol vapor first enters the steam tank through the inlet pipe, then is conveyed to the first receiving pipe by the first conveying pipe, and finally enters the cyclone separator. Upon entering the cyclone separator, the hot alcohol vapor comes into full contact with the hot carrageenan filling it. Utilizing the difference in solubility between alcohol and carrageenan, the alcohol vapor is rapidly separated. Simultaneously, the sealing plug design at the top of the cyclone separator facilitates the operator's filling of the hot carrageenan. Subsequently, at the bottom of the cyclone separator, the filter tube plays a crucial filtration role; its internal first filter effectively intercepts impurities from the precipitated carrageenan. The solenoid valve on the surface can precisely control the outflow speed and amount of carrageenan in the filter tube, ensuring the stability of the filtration effect. The carrageenan filtered through the filter tube will fall onto the filter cloth in the storage cylinder, and then the filter cloth will separate the carrageenan into solid and liquid. The two handles on the top of the first fixing ring make it easy for the operator to remove the filter cloth for subsequent cleaning. At the same time, the hot alcohol vapor in the cyclone separator will be transported to the second receiving pipe through the second conveying pipe and finally enter the return tank. The hot alcohol vapor in the return tank will be transported back to the steam tank through the return pipe, forming a hot alcohol vapor recycling.

[0007] Preferably, a support plate is fixedly connected to the top of the first support frame and the side of the second support frame. An electric push rod is fixedly installed on the side of the support plate. A horizontal plate is fixedly connected to one end of the electric push rod, and a cover plate is fixedly connected to the side of the horizontal plate. By adopting the above technical solution and setting an electric push rod, the baffle on the horizontal plate can be moved horizontally. During the purification process, the liquid is prevented from causing pollution and damage to the surrounding environment and equipment. At the same time, the design of the baffle also takes into account the safety of the operators and avoids injury from liquid splashing during operation.

[0008] Preferably, a plurality of brackets are fixedly connected to the bottom of the support platform, and a silicone pad is fixedly connected to the bottom of each bracket. By adopting the above technical solution and setting up several supports and silicone pads at the bottom of the supports, the stability of the entire device can be enhanced. During the operation of the purification device, displacement caused by vibration can be effectively reduced, ensuring the smooth progress of the purification process.

[0009] Preferably, a discharge pipe is fixedly connected to the side of the storage cylinder, and a manual valve is fixedly installed on the surface of the discharge pipe; By adopting the above technical solution and by setting up a discharge pipe and a manual valve on its surface, the liquid in the storage tank can be discharged conveniently and quickly after purification. The design of the manual valve allows the operator to accurately control the discharge volume and discharge speed of the liquid according to actual needs, avoiding excessive or insufficient discharge.

[0010] Preferably, the top of the reflux tank is movably connected to a cover plate via a hinge, and the cover plate and the side of the reflux tank are both fixedly connected to a fixing block, with screws threaded into the two fixing blocks. By adopting the above technical solution, and by setting a cover plate and using a connection method of fixing blocks and screws, the cover plate can be opened conveniently and quickly when it is necessary to clean the reflux tank or perform maintenance, so that the inside of the reflux tank can be thoroughly cleaned or repaired.

[0011] Preferably, a sealing ring is fixedly connected to the bottom of the cover plate; By adopting the above technical solution and setting a sealing ring, the sealing performance of the reflux tank can be effectively enhanced when the cover is closed, preventing external impurities from entering the reflux tank and avoiding leakage of steam or odor generated during the purification process.

[0012] Preferably, a second receiving ring is fixedly connected inside the reflux tank, a second fixing ring overlaps the top of the second receiving ring, a second filter screen is fixedly connected inside the second fixing ring, two lifting rings are fixedly connected to the top of the second fixing ring, a magnetic layer is provided on the top of the second receiving ring, and the material of the second fixing ring is ferrous material. By adopting the above technical solution, and by setting a second receiving ring, a second fixing ring, a second filter screen, a lifting ring, and a magnetic layer, the hot alcohol vapor returning to the reflux tank can be filtered a second time during the purification process using the second filter screen to remove impurities and improve the purification quality of carrageenan. At the same time, the second fixing ring overlaps the second receiving ring and is fixed by mutual attraction between the magnetic layer and the ferrous material of the second fixing ring, making the installation and removal of the second filter screen convenient and quick, and facilitating subsequent cleaning or replacement of the second filter screen. The lifting ring makes it easy for operators to lift the second fixing ring.

[0013] Preferably, the inner wall surface of the cyclone separator is provided with an anti-adhesion layer, and the anti-adhesion layer is made of polytetrafluoroethylene; By adopting the above technical solution and setting a polytetrafluoroethylene anti-adhesion layer, the adhesion of tiny particles generated during the carrageenan purification process to the inner wall of the cyclone separator can be effectively reduced, thereby reducing the problem of decreased separation efficiency caused by particle adhesion and ensuring that the cyclone separator can continuously and stably carry out gas-solid separation operation.

[0014] In summary, this application includes at least one of the following beneficial technical effects: This high-efficiency carrageenan purification device, by incorporating a cyclone separator, allows hot carrageenan to be filled into the separator during the purification process, followed by rapid purification using hot alcohol vapor. The cyclone separator is then kept at a suitable temperature. Under this temperature condition, the solubility of alcohol in carrageenan is effectively reduced, allowing alcohol vapor to be quickly separated from the mixture, minimizing alcohol residue in the purified material, avoiding waste, lowering production costs, and resolving the adverse effects of residual alcohol on subsequent product processing and use. Furthermore, the solid-liquid contact method enables rapid separation and purification of carrageenan. Furthermore, no stirring device is installed during the entire purification process, which avoids the situation where carrageenan precipitates in flocculent form and wraps around the blades of the stirring tank. This not only ensures the normal operation of the stirring process and guarantees the purification effect, but also eliminates the need to spend a lot of manpower and time to remove the carrageenan flocculent material wrapped around the blades during subsequent equipment cleaning, greatly improving production efficiency. In addition, the alcohol vapor separated from the cyclone separator can be recycled and reused, saving costs. The filter tube is located at the top of the storage tank. The precipitated carrageenan is initially filtered through the first filter screen in the filter tube. After filtration, the carrageenan falls onto the filter cloth in the storage tank for solid-liquid separation. In practice, hot alcohol vapor first enters the steam tank through the inlet pipe, then is conveyed to the first receiving pipe by the first conveying pipe, and finally enters the cyclone separator. Upon entering the cyclone separator, the hot alcohol vapor comes into full contact with the hot carrageenan filling it. Utilizing the difference in solubility between alcohol and carrageenan, the alcohol vapor is rapidly separated. Simultaneously, the sealing plug design at the top of the cyclone separator facilitates the operator's filling of the hot carrageenan. Subsequently, at the bottom of the cyclone separator, the filter tube plays a crucial filtration role; its internal first filter effectively intercepts impurities from the precipitated carrageenan. The solenoid valve on the surface can precisely control the outflow speed and amount of carrageenan in the filter tube, ensuring the stability of the filtration effect. The carrageenan filtered through the filter tube will fall onto the filter cloth in the storage cylinder, and then the filter cloth will separate the carrageenan into solid and liquid. The two handles on the top of the first fixing ring make it easy for the operator to remove the filter cloth for subsequent cleaning. At the same time, the hot alcohol vapor in the cyclone separator will be transported to the second receiving pipe through the second conveying pipe and finally enter the return tank. The hot alcohol vapor in the return tank will be transported back to the steam tank through the return pipe, forming a hot alcohol vapor recycling. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0018] Example 1: A high-efficiency carrageenan purification device, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The system includes a support platform 1, with a first support frame 2 and a second support frame 8 fixedly connected to the top of the support platform 1. A steam tank 3 is fixedly connected inside the first support frame 2, and a return tank 9 is fixedly connected inside the second support frame 8. An inlet pipe 29 and a third receiving pipe 31 are fixedly connected to one side surface of the steam tank 3. A third flange 30 is fixedly connected to the surface of the inlet pipe 29. A first conveying pipe 4 is fixedly connected to the top surface of the steam tank 3. A first receiving pipe 5 is fixedly installed at one end of the first conveying pipe 4 via a first flange 24. A cyclone separator 6 is fixedly installed on the surface of the first receiving pipe 5. A sealing plug 44 is snapped onto the top of the cyclone separator 6. A filter tube 26 is threaded onto the bottom of the cyclone separator 6. A first filter screen 28 is fixedly connected inside the filter tube 26. A solenoid valve 27 is fixedly installed on the surface of the filter tube 26. A second conveying pipe 23 is fixedly connected to the surface of the cyclone separator 6. A second receiving pipe 10 is fixedly installed at one end of the second conveying pipe 23 through a second flange 25. The second receiving pipe 10 is fixedly connected inside the return tank 9. A return pipe 32 is fixedly connected to the surface of the return tank 9. One end of the return pipe 32 is fixedly installed on the surface of the third receiving pipe 31 through a fourth flange 33. A storage cylinder 7 is placed on top of the support platform 1. A first receiving ring 17 is fixedly connected inside the storage cylinder 7. A first fixing ring 18 overlaps the top of the first receiving ring 17. A filter cloth 19 is fixedly connected inside the first fixing ring 18. Two handles 20 are fixedly connected to the top of the first fixing ring 18. A filter tube 26 is located on top of the storage cylinder 7. By setting a cyclone separator 6, hot carrageenan is filled into the cyclone separator 6 during the purification process. Then, it is rapidly purified using hot alcohol vapor. Subsequently, the inside of the cyclone separator 6 is kept at a suitable temperature. Under this temperature condition, on the one hand, the solubility of alcohol in carrageenan can be effectively reduced, allowing alcohol vapor to be quickly separated from the mixture, reducing alcohol residue in the purified material, avoiding alcohol waste, reducing production costs, and solving the problem of residual alcohol. On the one hand, the adverse effects of subsequent product processing and use can be mitigated by the solid-liquid contact method, which enables rapid separation and purification of carrageenan. Moreover, no stirring device is used during the entire purification process, thus avoiding the situation where carrageenan precipitates in flocculent form and wraps around the blades of the stirring tank. This not only ensures the normal operation of the stirring process and guarantees the purification effect, but also eliminates the need to spend a lot of manpower and time to remove the carrageenan flocculent material wrapped around the blades during subsequent equipment cleaning, greatly improving production efficiency. In addition, the alcohol vapor separated from the cyclone separator 6 can be recovered and reused, saving costs. The filter tube 26 is located at the top of the storage cylinder 7. The precipitated carrageenan is initially filtered by the first filter screen 28 in the filter tube 26. After filtration, the carrageenan falls onto the filter cloth 19 in the storage cylinder 7 for solid-liquid separation. In practice, firstly, hot alcohol vapor enters the steam tank 3 through the inlet pipe 29, is then conveyed by the first conveying pipe 4 to the first receiving pipe 5, and finally enters the cyclone separator 6. Upon entering the cyclone separator 6, the hot alcohol vapor comes into full contact with the hot carrageenan filling it. Utilizing the difference in solubility between alcohol and carrageenan, rapid separation of the alcohol vapor is achieved. Simultaneously, the sealing plug 44 at the top of the cyclone separator 6 is designed to facilitate the operator's filling of the hot carrageenan. Subsequently, at the bottom of the cyclone separator 6, the filter tube 26 plays a crucial filtration role. Its internal first filter screen 28 effectively intercepts impurities from the precipitated carrageenan, while the surface electrostatic precipitate... The solenoid valve 27 can precisely control the outflow rate and amount of carrageenan in the filter tube 26 to ensure the stability of the filtration effect. The carrageenan filtered by the filter tube 26 will fall onto the filter cloth 19 in the storage cylinder 7, and then the filter cloth 19 will separate the carrageenan into solid and liquid. Then, the two handles 20 on the top of the first fixing ring 18 are designed to make it easy for the operator to remove the filter cloth 19 for subsequent cleaning. At the same time, the hot alcohol vapor in the cyclone separator 6 will be transported to the second receiving pipe 10 through the second conveying pipe 23 and finally enter the return tank 9. The hot alcohol vapor in the return tank 9 will be transported back to the steam tank 3 through the return pipe 32 to form a hot alcohol vapor recycling.

[0019] Please see Figure 1 Support plates 11 are fixedly connected to the top of the first support frame 2 and the side of the second support frame 8. An electric push rod 12 is fixedly installed on the side of the support plate 11. A horizontal plate 13 is fixedly connected to one end of the electric push rod 12. A cover plate 14 is fixedly connected to the side of the horizontal plate 13. By setting the electric push rod 12, the cover plate 14 on the horizontal plate 13 can be moved horizontally. During the purification process, the liquid is prevented from causing pollution and damage to the surrounding environment and equipment. At the same time, the design of the cover plate 14 also takes into account the safety of the operators and avoids injury due to liquid splashing during operation. Several brackets 15 are fixedly connected to the bottom of the support platform 1. A silicone pad 16 is fixedly connected to the bottom of the brackets 15. By setting several brackets 15 and the silicone pad 16 at the bottom of the brackets 15, the stability of the entire device can be enhanced. During the operation of the purification device, the displacement caused by vibration is effectively reduced, and the purification process is ensured to proceed smoothly.

[0020] Please see Figure 2 and Figure 5A discharge pipe 21 is fixedly connected to the side of the storage tank 7. A manual valve 22 is fixedly installed on the surface of the discharge pipe 21. By setting the discharge pipe 21 and the manual valve 22 on its surface, the liquid in the storage tank 7 can be discharged conveniently and quickly after purification. The design of the manual valve 22 allows the operator to accurately control the discharge volume and discharge speed of the liquid according to actual needs, avoiding excessive or insufficient discharge. The top of the reflux tank 9 is movably connected to the cover plate 34 by a hinge. The cover plate 34 and the side of the reflux tank 9 are both fixedly connected to the fixing blocks 35. The two fixing blocks 35 are internally threaded with screws 36. By setting the cover plate 34 and the connection method of fixing blocks 35 and screws 36, the cover plate 34 can be opened conveniently and quickly when it is necessary to clean the reflux tank 9 or perform maintenance, so that the interior of the reflux tank 9 can be thoroughly cleaned or repaired.

[0021] Please see Figure 5 , Figure 6 and Figure 7 A sealing ring 37 is fixedly connected to the bottom of the cover plate 34. By setting the sealing ring 37, the sealing performance of the reflux tank 9 can be effectively enhanced when the cover plate 34 is closed, preventing external impurities from entering the reflux tank 9 and avoiding the leakage of steam or odors generated during the purification process. A second receiving ring 38 is fixedly connected inside the reflux tank 9. A second fixing ring 39 overlaps the top of the second receiving ring 38. A second filter screen 40 is fixedly connected inside the second fixing ring 39. Two lifting rings 41 are fixedly connected to the top of the second fixing ring 39. A magnetic layer 42 is provided on the top of the second receiving ring 38. The second fixing ring 39 is made of ferrous material. By setting the second receiving ring 38, the second fixing ring 39, the second filter screen 40, the lifting rings 41, and the magnetic layer 42, the second filter screen 40 can be used to filter the heat flowing back into the reflux tank 9 during the purification process. The alcohol vapor undergoes secondary filtration to remove impurities and improve the purification quality of carrageenan. Simultaneously, the second fixing ring 39 overlaps the second receiving ring 38 and is attracted and fixed to the ferrous material of the second fixing ring 39 via the magnetic layer 42. This makes the installation and removal of the second filter screen 40 convenient and quick, facilitating subsequent cleaning or replacement. The lifting ring 41 allows operators to easily lift the second fixing ring 39. The inner wall surface of the cyclone separator 6 is provided with an anti-adhesion layer 43 made of polytetrafluoroethylene (PTFE). This PTFE anti-adhesion layer 43 effectively reduces the adhesion of tiny particles generated during carrageenan purification to the inner wall of the cyclone separator 6, mitigating the decrease in separation efficiency caused by particle adhesion and ensuring the cyclone separator 6 can continuously and stably perform gas-solid separation operations.

[0022] The implementation principle of this application embodiment is as follows: First, the cover plate 34 at the top of the reflux tank 9 is closed and locked by the fixing block 35 and screw 36. Then, the sealing ring 37 at the bottom of the cover plate 34 ensures that the reflux tank 9 is sealed. Then, it is confirmed that the first fixing ring 18 in the storage cylinder 7 has been attached to the first receiving ring 17. Then, the second fixing ring 39 in the reflux tank 9 is attracted to the second receiving ring 38 by the magnetic layer 42. Then, all flanges are firmly connected, and the solenoid valve 27 and the manual valve 22 are in the closed state. After the inspection is completed, the electric push rod 12 on the first support frame 2 and the second support frame 8 is controlled. Then, the horizontal plate 13 is pushed to drive the cover plate 14 to move horizontally, covering the filter tube 26 and the area above the storage cylinder 7 to prevent liquid splashing in subsequent operations. Then, the external equipment is connected to the inlet pipe 29 through the third flange 30 and hot alcohol vapor is introduced into the steam tank 3. At the same time, the sealing plug 44 at the top of the cyclone separator 6 is opened, and hot carrageenan raw material is filled into the cyclone separator 6. After filling, the sealing plug 44 is tightened again. Then, the hot alcohol vapor in the steam tank 3 enters the first receiving pipe 5 through the first conveying pipe 4 and the first flange 24, and finally enters the cyclone separator 6. Then, the hot alcohol vapor comes into full contact with the hot carrageenan in the cyclone separator 6. By utilizing the difference in solubility, the alcohol vapor and carrageenan are initially separated. During the separation, the polytetrafluoroethylene anti-adhesion layer 43 on the inner wall of the cyclone separator 6 can effectively reduce particle adhesion. Subsequently, the separated hot alcohol vapor enters the second receiving pipe 10 through the second conveying pipe 23 and the second flange 25 on the surface of the cyclone separator 6, and finally flows into the return tank 9. Then, the steam is first filtered through the second filter screen 40 in the return tank 9 to remove small impurities, and then temporarily stored in the return tank 9 to complete the first alcohol recovery. Then, the heat-insulating environment inside the cyclone separator 6 reduces the solubility of alcohol. Then, carrageenan precipitates out in solid form. The solenoid valve 27 on the surface of the filter tube 26 is opened to control the precipitated carrageenan to pass through the first filter screen 28 inside the filter tube 26 for preliminary filtration. The filtered carrageenan slowly falls onto the filter cloth 19 of the storage cylinder 7 below. Then, the filter cloth 19 in the storage cylinder 7 performs secondary filtration on the carrageenan. The solid carrageenan remains on the filter cloth 19, while the liquid permeates to the bottom of the storage cylinder 7 for temporary storage, thus achieving complete solid-liquid separation. Then, the return pipe 32 between the return tank 9 and the steam tank 3 is opened, and the filtered hot alcohol vapor in the return tank 9 is sent back to the steam tank 3 to form a closed-loop alcohol circulation, reducing the waste of consumables. The bracket 15 and silicone pad 16 at the bottom of the support platform 1 enhance the stability of the device and prevent displacement caused by vibration during operation. After purification, close the solenoid valve 27, open the manual valve 22 on the side discharge pipe 21 of the storage cylinder 7, control the discharge volume according to the needs, and discharge the liquid at the bottom of the storage cylinder 7. After discharge, close the manual valve 22, and take out the filter cloth 19 and the attached pure carrageenan through the handle 20 on the top of the first fixing ring 18 inside the storage cylinder 7 for subsequent processing. If the second filter screen 40 needs to be cleaned, the second fixing ring 39 can be lifted through the lifting ring 41, disassembled, cleaned or replaced. Finally, unscrew the screws 36 on the fixing block 35, open the cover plate 34 of the return tank 9 through the hinge, and thoroughly clean the inside of the return tank 9 and the second filter screen 40. After cleaning, reset the second fixing ring 39, close the cover plate 34 and lock the screws 36 to ensure that the sealing ring 37 is sealed. Control the electric push rod 12 to retract the cover plate 14, clean the surface of the cyclone separator 6 and the residual material on the filter tube 26. If it is necessary to clean the steam tank 3, the cleaning liquid can be introduced through the inlet pipe 29. After completion, it can be discharged to prepare for the next purification.
