[0002] Amino acids are the main units that make up proteins in living organisms. In order to obtain amino acids with higher purity, crystallization is often used to purify amino acids. Amino acids obtained by crystallization are of high quality, and the purification process is highly efficient and safe. Among them, glutamic acid is a common non-essential amino acid.

[0003] Among them, sodium glutamate is a salt formed by sodium ions and glutamate ions, which is often used to make seasonings such as MSG to enhance the flavor. Sodium glutamate can also be obtained by evaporation and crystallization during the preparation process.

[0004] The utility model with the publication number CN206746030U discloses a device for amino acid evaporation crystallization, including a crystallization tank, a heating ring with a hollow structure is sleeved on the outer side of the crystallization tank, the heating ring can slide down along the crystallization tank by itself under the action of gravity, the height of the heating ring is 1 / 5 to 1 / 4 of the height of the crystallization tank, the hollow structure of the heating ring is filled with heat transfer oil, the inlet and outlet of the heat transfer oil and the center of the heating ring are on the same straight line; at least two wire seats are fixedly connected to the support frame, each of which is respectively connected to a screw rod extending vertically upward to the bottom surface of the heating ring through a thread, the screw rod provides support for the heating ring, and the screw rod is evenly distributed along the circumference of the heating ring. This patent application uses a heating ring to heat the liquid in the crystallization tank layer by layer from top to bottom. As the liquid level decreases, the heating ring is moved downward by rotating the screw rod. Since the liquid heated each time is in the uppermost layer, it evaporates directly after the temperature is reached, which greatly shortens the time used for crystallization and improves the crystallization efficiency.

DETAILED DESCRIPTION

[0036] The following is combined with Figures 1 to 9This application is described in further detail.

[0037] The embodiment of the present application discloses a high-efficiency and low-energy consumption amino acid evaporation crystallization device and process, which recovers the water vapor generated by the evaporation of sodium glutamate solution and performs heat preservation treatment on the sodium glutamate during the evaporation and crystallization process; at the same time, the present invention can take out the sodium glutamate after evaporation and crystallization without manual methods, and has higher efficiency and safety.

[0038] Embodiment 1:

[0039] See also Figure 1 as well as Figure 2 A high-efficiency and low-energy consumption amino acid evaporation crystallization device comprises a heating cylinder 1, an air outlet pipe 2 is installed on the upper end surface of the heating cylinder 1, a spiral groove 3 is opened inside the side wall of the heating cylinder 1, a transition pipe 4 connected with the air outlet pipe 2 is installed on the air outlet pipe 2, and the end of the transition pipe 4 away from the air outlet pipe 2 is connected with the spiral groove 3.

[0040] See also Figure 2 , Figure 3 as well as Figure 5 A rotating shaft 11 extending vertically is rotatably installed on the upper end surface of the heating cylinder 1, a driving motor 12 is installed on the upper end surface of the rotating shaft 11, a moving block 13 extending left and right and moving up and down is installed on the part of the rotating shaft 11 located inside the heating cylinder 1, a scraper 14 is installed on the right side of the moving block 13, a discharge trough 15 penetrating vertically is provided on the lower end surface of the heating cylinder 1, and an electronic hygrometer 16 is installed on the upper end surface of the heating cylinder 1.

[0041] The lower end of the spiral groove 3 is connected to the outside. During operation, the discharge groove 15 is sealed, and in the initial state, the heating cylinder 1 is filled with sodium glutamate solution. The heating cylinder 1 is heated by an external heating device (resistance wire, etc.). The water vapor generated during the heating process can enter the spiral groove 3 through the air outlet pipe 2 and the transition pipe 4, and then the water vapor in the spiral groove 3 can keep the heating cylinder 1 warm, reduce the heat exchange between the outer wall of the heating cylinder 1 and the external environment, and reduce the pollution of waste heat to the environment.

[0042] After the water vapor condenses inside the spiral groove 3, the inside of the heating tube 1 is in a negative pressure state. Under the negative pressure state, the humidity inside the heating tube 1 is low and the water vapor evaporates quickly, further accelerating the evaporation rate of the sodium glutamate solution water, and the condensed water droplets flow out through the bottom of the spiral groove 3.

[0043] See also Figures 3 to 5An elastic telescopic rod 131 is installed on the lower end surface of the moving block 13, and a moving connecting block 132 is installed on the end of the elastic telescopic rod 131 away from the moving block 13. A pressing roller 133 extending left and right is installed on the left end surface of the moving connecting block 132 through a bearing, which can press the sodium glutamate solid at the bottom of the heating cylinder 1. A counterweight block 134 is installed on the side of the pressing roller 133 away from the moving connecting block 132 to ensure that the pressing roller 133 will not be displaced in the up and down directions when pressing the sodium glutamate. An annular bevel rack plate 135 is installed at the bottom of the heating cylinder 1, and a bevel gear 136 matching the annular bevel rack plate 135 is installed on the right side of the pressing roller 133.

[0044] After heating for a period of time, the electronic hygrometer 16 is manually observed. If the reading of the electronic hygrometer 16 reaches a certain value, it indicates that the sodium glutamate solution inside the heating cylinder 1 is completely evaporated and dry sodium glutamate is obtained. At this time, the moving block 13 is pushed downward by an external driving force (electric push rod, etc.). During the downward movement of the moving block 13, the elastic telescopic rod 131 drives the moving connecting block 132 to move downward.

[0045] The bevel gear 136 can rotate relatively around the pressing roller 133 at a small angle to ensure that the bevel gear 136 and the annular bevel rack plate 135 can be adaptively fine-tuned to mesh, avoid the problem of tooth jamming between the bevel gear 136 and the annular bevel rack plate 135, and improve the use effect of the device.

[0046] During the downward movement of the moving connecting block 132, the pressing roller 133 first contacts the sodium glutamate solid at the bottom of the heating cylinder 1. At this time, the bevel gear 136 and the annular bevel rack plate 135 are fine-tuned and meshed. During the rotation of the rotating shaft 11, the pressing roller 133 is driven to rotate circumferentially. During the circumferential rotation of the pressing roller 133 around the rotating shaft 11, the bevel gear 136 and the annular bevel rack plate 135 are meshed with each other and can also rotate on its own. Therefore, the pressing roller 133 during the rotation process can crush the sodium glutamate after evaporation and crystallization to obtain sodium glutamate powder, thereby avoiding agglomeration of sodium glutamate after evaporation and crystallization, which affects the subsequent removal of sodium glutamate.

[0047] When the sodium glutamate solid is pressed, the moving block 13 continues to move downward, and the elastic telescopic rod 131 contracts at this time to make way for the moving block 13, and the moving connecting block 132 no longer moves. During the downward movement of the moving block 13, the scraper 14 is driven to move downward and abut against the inner bottom surface of the heating cylinder 1. At this time, the discharge chute 15 is opened and the driving motor 12 is started. During the rotation of the driving motor 12, the rotating shaft 11 is driven to rotate. During the rotation of the rotating shaft 11, the scraper 14 is driven to rotate through the moving block 13. During the rotation of the scraper 14, the sodium glutamate powder can be scraped out from the discharge chute 15, thereby reducing the tediousness of removing the sodium glutamate powder by manual methods, and at the same time reducing the risk of workers entering the heating cylinder 1.

[0048] See also Figure 5 as well as Figure 6 In order to avoid relative sliding between the sodium glutamate solid and the pressing roller 133, a bidirectional thread groove 137 is provided on the circumferential surface of the pressing roller 133 of the present invention to increase the friction between the sodium glutamate and the pressing roller 133. An L-shaped fixed frame 138 is provided on the left side of the upper end surface of the movable connecting block 132. The vertical section of the fixed frame 138 is fixedly connected to the movable connecting block 132. The horizontal section of the fixed frame 138 is located directly above the pressing roller 133. A scraping plate 139 that slides left and right is provided on the lower end surface of the horizontal section of the fixed frame 138 to scrape off the sodium glutamate powder attached to the surface of the pressing roller 133. The scraping protrusion 130 that matches the bidirectional thread groove 137 is provided on the lower end surface of the scraping plate 139.

[0049] During specific operation, the sodium glutamate solid can be pressed during the rotation of the pressing roller 133. The bidirectional threaded groove 137 can increase the friction between the sodium glutamate and the pressing roller 133 during the rotation of the pressing roller 133, thereby avoiding the problem that the sodium glutamate solid and the pressing roller 133 remain relatively still and the pressing roller 133 cannot effectively press the sodium glutamate solid. At the same time, during the rotation of the pressing roller 133, the bidirectional threaded groove 137 synchronously drives the scraper plate 139 to move back and forth along the horizontal plate of the fixed frame 138, so that the scraper plate 139 can scrape off the sodium glutamate powder attached to the surface of the pressing roller 133, and the scraping protrusion 130 can scrape off the sodium glutamate powder inside the bidirectional threaded groove 137, thereby avoiding the problem that the sodium glutamate powder blocks the bidirectional threaded groove 137, resulting in a decrease in the friction between the sodium glutamate solid and the pressing roller 133.

[0050] Replay Figure 3 In order to ensure the uniformity of heating of the sodium glutamate solution during the evaporation and crystallization process, the rotating shaft 11 of the present invention is equipped with a horizontal forward stirring rod 111 on the front end surface located inside the heating cylinder 1, and a plurality of stirring rods 112 evenly distributed from front to back are installed on the lower side of the circumferential surface of the stirring rod 111.

[0051] During specific operation, the stirring rod 112 is driven to rotate by the stirring connecting rod 111 during the rotation of the rotating shaft 11. The sodium glutamate solution can be stirred during the rotation of the stirring rod 112, so that the sodium glutamate solution moves irregularly, thereby ensuring the uniformity of the sodium glutamate solution during the heating process.

[0052] Example 2: See Figure 7 as well as Figure 8On the basis of the first embodiment, in order to further improve the utilization efficiency of water vapor in the evaporation and crystallization process, a preheating cylinder 5 is arranged on the right side of the heating cylinder 1 of the present invention, which can hold the sodium glutamate solution, and an inlet 51 is installed on the right side of the upper end surface of the preheating cylinder 5. The heating cylinder 1 and the preheating cylinder 5 are connected by a horizontal frame 52, and a water pump 53 is installed on the horizontal frame 52, which can pump the sodium glutamate solution in the preheating cylinder 5 into the heating cylinder 1. The water outlet of the water pump 53 is connected to the heating cylinder 1 through the water outlet pipe 54, and the water inlet of the water pump 53 is connected to the preheating cylinder 5 through the water inlet pipe 55. A preheating pipe 56 matched with the air outlet pipe 2 is installed on the preheating cylinder 5 to preheat the sodium glutamate solution.

[0053] There are multiple preheating tubes 56 evenly arranged around the circumference and the preheating tubes 56 are of a vertical through structure. A transition box 57 that is through is installed on the upper ends of the preheating tubes 56, and the end of the air outlet pipe 2 away from the heating tube 1 is through-connected with the transition box 57.

[0054] The diameter of the transition pipe 4 is smaller than that of the air outlet pipe 2, so a large amount of water vapor inside the air outlet pipe 2 remains after entering the transition pipe 4. During specific operation, before the sodium glutamate solution inside the heating cylinder 1 evaporates and crystallizes, the sodium glutamate solution is poured into the preheating cylinder 5 through the inlet 51. At this time, excess water vapor enters the transition box 57 through the air outlet pipe 2, and the water vapor enters the preheating tube 56 through the transition box 57. Then, the water vapor inside the preheating tube 56 can preheat the sodium glutamate solution. The preheating tube 56 is circumferentially provided with a plurality of sodium glutamate solution to make the sodium glutamate solution inside the preheating cylinder 5 more evenly heated.

[0055] Therefore, the water vapor and the preheating tube 56 cooperate with each other to preheat the sodium glutamate solution inside the preheating cylinder 5, and at the same time, the waste heat of the water vapor can be utilized, which not only reduces the pollution of waste heat to the environment, but also makes the evaporation and crystallization efficiency of the preheated sodium glutamate solution higher after entering the heating cylinder 1.

[0056] The water vapor condenses into water droplets inside the preheating tube 56 and adheres to the inside of the preheating tube 56 .

[0057] In order to prevent the water droplets attached to the inner wall of the preheating tube 56 from affecting the heat conduction effect of the preheating tube 56, a rotating coupling 561 is arranged inside the preheating tube 56 of the present invention. The upper end of the rotating coupling 561 is installed on the top of the preheating tube 56 through a bearing. A spiral blade 562 is installed on the circumferential surface of the rotating coupling 561, which is tightly attached to the inner wall of the preheating tube 56. A pulley 563 is installed at one end of the rotating coupling 561 located in the transition box 57, and the pulleys 563 are connected by a belt 564 for transmission.

[0058] Any one of the rotating couplings 561 is connected to the output shaft of an external motor (not shown in the figure). During specific operation, the external motor is started, and the output shaft of the external motor drives any one of the rotating couplings 561 to rotate during rotation. During rotation of the rotating coupling 561, the pulley 563 and the belt 564 cooperate with each other to drive the remaining rotating couplings 561 to rotate. During rotation of the rotating coupling 561, the spiral blade 562 is driven to rotate. During rotation of the spiral blade 562, the water droplets attached to the inside of the preheating tube 56 can be pushed downward and discharged from the bottom of the preheating tube 56 to prevent the water droplets attached to the inner wall of the preheating tube 56 from affecting the heat conduction effect of the preheating tube 56. At the same time, the spiral blade 562 can also push the water vapor downward to prevent the water vapor from being deposited and condensed inside the transition box 57, resulting in water droplets remaining inside the transition box 57 or even forming water nests, which affects the efficiency of water vapor entering the preheating tube 56.

[0059] When the sodium glutamate solution in the heating cylinder 1 is completely evaporated and crystallized, the actions of Example 1 are repeated and the water pump 53 is started. The water pump 53 can pump the sodium glutamate solution into the heating cylinder 1 through the cooperation of the water inlet pipe 55 and the water outlet pipe 54, thereby continuously evaporating and crystallizing the sodium glutamate solution.

[0060] Finally, see Fig. 9 The present invention also provides a high-efficiency and low-energy consumption amino acid evaporation crystallization process, and its use method includes the following steps: S1: blocking treatment, pumping sodium glutamate solution into the preheating cylinder 5 through the outlet, blocking the discharge trough 15, and pumping sodium glutamate solution into the heating cylinder 1 through the water pump 53.

[0061] S2: Heating treatment, heating the heating tube 1 by an external heating device (resistance wire, etc.), the water vapor generated during the heating process can enter the spiral groove 3 through the outlet pipe 2 and the transition pipe 4, and the heating tube 1 is kept warm;

[0062] S3: Preheating treatment, excess water vapor enters the transition box 57 through the outlet pipe 2, and the water vapor enters the preheating tube 56 through the transition box 57, and then the water vapor in the preheating tube 56 can preheat the sodium glutamate solution.

[0063] S4: Material taking process, during the downward movement of the moving connecting block 132, the pressing roller 133 first contacts the sodium glutamate solid at the bottom of the heating cylinder 1, at which time the bevel gear 136 and the annular bevel rack plate 135 are fine-tuned and meshed, and the rotating shaft 11 drives the pressing roller 133 to rotate circumferentially during the rotation of the rotating shaft 11. During the circumferential rotation of the pressing roller 133 around the rotating shaft 11, the bevel gear 136 and the annular bevel rack plate 135 are meshed with each other and can also rotate on their own, and then the pressing roller 133 during the rotation process can crush the sodium glutamate after evaporation and crystallization to obtain sodium glutamate powder.

[0064] When the sodium glutamate solid is pressed, the moving block 13 continues to move downward, and the elastic telescopic rod 131 contracts at this time to make way for the moving block 13, and the moving connecting block 132 no longer moves. During the moving block 13 moving downward, the scraper 14 is driven to move downward and abut against the inner bottom surface of the heating cylinder 1. At this time, the discharge chute 15 is opened, and the driving motor 12 is started. During the rotation of the driving motor 12, the rotating shaft 11 is driven to rotate. During the rotation of the rotating shaft 11, the scraper 14 is driven to rotate through the moving block 13. During the rotation of the scraper 14, the sodium glutamate powder can be scraped out from the discharge chute 15.
