Conventional extraction processes involve flocculation followed by treatment with polymeric ultrafiltration or nanofiltration membranes. However, directly feeding flocculated material into ultrafiltration membranes can easily cause membrane clogging and concentration gradients, requiring frequent membrane cleaning, resulting in low production efficiency. Furthermore, the fermentation process typically involves a complex and harsh environment, significantly impacting the lifespan of organic membranes. Summary of the Invention:

[0016] Reference Figure 1As shown, this utility model is a ceramic membrane device for amino acid production, comprising a base 1 and a main controller 2, a storage tank 3, a supply pump 4, a booster pump 5, a first ceramic membrane tube 6, and a second ceramic membrane tube 7 located on the base 1. The storage tank 3 is equipped with a heat exchange coil 31 for auxiliary heating of the feed liquid. The lower part of the storage tank 3 is split by the supply pump 4 to a first branch pipe 41 and a first return pipe 42. The first branch pipe 41 is connected to the first ceramic membrane tube 6, the second ceramic membrane tube 7, and the first return pipe 42 after passing through the booster pump 5. The other ends of the first ceramic membrane tube 6 and the second ceramic membrane tube 7 are connected to the second return pipe 43.

[0017] Both the first branch pipe 41 and the second return pipe 43 are connected to a drain pipe 40. The drain pipe 40 is equipped with a first drain valve 410 corresponding to the first branch pipe 41 and a second drain valve 430 corresponding to the second return pipe 43. The drain pipe 40 is set in the opposite direction to the normal flow direction of the first branch pipe 41 or the second return pipe 43. When draining, the corresponding valve needs to be controlled for adjustment.

[0018] A first control valve 411 is provided at the connection end between the first branch pipe 41 and the liquid supply pump 4. A second control valve 412 is provided at the end of the first branch pipe 41. A third control valve 61 is provided at the input end of the first ceramic membrane tube 6, and a fourth control valve 62 is provided at the output end. A fifth control valve 71 is provided at the input end of the second ceramic membrane tube 7, and a sixth control valve 72 is provided at the output end. A seventh control valve 421 is provided in the first return pipe 42, and an eighth control valve 431 is provided in the second return pipe 43. The eighth control valve 431 is located in the middle section of the second return pipe 43. After passing through the eighth control valve 431, the liquid passes through the flow meter 8 and finally enters the storage tank 3 from the outlet of the second return pipe 43.

[0019] The first ceramic membrane tube 6 has a first ceramic membrane tube shell valve 60, and the second ceramic membrane tube 7 has a second ceramic membrane tube shell valve 70. The first ceramic membrane tube 6 is provided with a first clear liquid discharge pipe 66 and a corresponding first clear liquid valve 661 at its end, and the second ceramic membrane tube 7 is provided with a second clear liquid discharge pipe 76 and a corresponding second clear liquid valve 761 at its end, for the clear liquid discharge of the feed liquid.

[0020] A connecting section 48 is provided between the first branch pipe 41 and the first return pipe 42, and a ninth control valve 481 is provided on the connecting section 48 to control whether the liquid flows directly to the first return pipe 42.

[0021] like Figure 2As shown, the main controller 2 includes a power-on button 21 and indicator light for the liquid supply pump 4, a power-off button 22 and indicator light for the feed pump 4, an emergency stop button 23, and a control panel 24 for the booster pump 5. The control panel 24 includes a booster pump switch button 25, a booster pump forward / reverse control button 26, and a booster pump frequency adjustment button 27.

[0022] The base 1 is equipped with pulleys to facilitate the movement of the equipment.

[0023] During implementation: Connect the power supply and introduce the feed liquid after disc separation into the storage tank 3. Open the first control valve 411, the second control valve 412, the third control valve 61, the fourth control valve 62, and the eighth control valve 431. Close the first drain valve 410, the ninth control valve 481, the first ceramic membrane tube valve 60, the first clear liquid valve 661, and the second drain valve 430. Partially open the seventh control valve 421. Turn on the power start button 21 of the supply pump 4. The feed liquid flows from the storage tank 3 through the impeller of the supply pump 4, the first branch pipe 41, and the booster pump 5, and then enters the first ceramic membrane tube 6. The concentrated liquid flows back into the storage tank 3 through the second return pipe 43 and the flow meter 8. The return fluid flow rate is controlled by the seventh control valve 421 and the eighth control valve 431. If the fluid viscosity is high and the flow rate is low, the booster pump 5 can be turned on. Press the booster pump switch button 25, select the booster pump forward / reverse control button 26, and adjust the frequency using the booster pump frequency adjustment button 27. After the pressure stabilizes, open the first clear liquid valve 661, and the clear liquid flows out through the outlet of the first clear liquid discharge pipe 66. After the clear liquid flow stabilizes, it is collected. After running for a period of time, the fluid temperature rises. For some temperature-sensitive amino acid fluids, the cooling water flow rate in the heat exchange coil 31 can be controlled to control the fluid temperature in the storage tank 3. After operation, open the first drain valve 410, the second drain valve 430, and the first ceramic membrane shell valve 60 to drain the residual liquid. After closing the valves, introduce cleaning agent to clean the pipes and ceramic membrane shell. Then open the drain valve to drain the cleaning liquid. Unlike polymer membranes, which need to be stored with water, ceramic membranes can be stored after being drained.

[0024] The usage method of the second ceramic membrane tube 7 is the same as that of the first ceramic membrane tube 6. Open the fifth control valve 71, the sixth control valve 72, the ninth control valve 481, and the eighth control valve 431; close the first drain valve 410, the first control valve 411, the third control valve 61, the second clear liquid valve 761, the second drain valve 430, the fourth control valve 62, and the second ceramic membrane tube shell valve 70; partially open the seventh control valve 421; and turn on the power start button 21 of the supply pump 4. The feed liquid enters the second ceramic membrane tube 7 from the storage tank 3 through the impeller of the supply pump 4 and the first branch pipe 41. The concentrated liquid flows back into the storage tank 3 through the second return pipe 43 and the flow meter 8. The flow rate of the return liquid is controlled by the seventh control valve 421 and the eighth control valve 431. After the pressure stabilizes, open the second clear liquid valve 761. The clear liquid flows out through the outlet of the second clear liquid discharge pipe 76. After the clear liquid flow stabilizes, it is collected. After running for a period of time, the temperature of the feed solution rises. For some temperature-sensitive amino acid feed solutions, the cooling water flow rate in the heat exchange coil 31 can be controlled to regulate the temperature of the feed solution in the storage tank 3. After operation, open the first drain valve 410, the first control valve 411, the second drain valve 430, and the second ceramic membrane shell valve 70 to drain the residual liquid. Then close the valves, introduce cleaning agent to clean the pipeline and ceramic membrane shell, and finally open the drain valve to drain the cleaning liquid.
