Description

[0001] The invention relates to the field of sodium fructose diphosphate processing, and in particular to a crystallization device in the sodium fructose diphosphate processing technology. Background Art

[0002] The production of sodium fructose diphosphate sterile powder is generally obtained by dissolving sodium fructose diphosphate sterile powder, sterilizing and filtering, crystallizing, solid-liquid separation, drying, sieving and weighing, and finally packaging. After the sodium fructose diphosphate is sterilized and filtered, it is necessary to use sterilized compressed air to press the filtrate into the crystallization tank, and then add sterilized alcohol and qualified sodium fructose diphosphate sterile raw materials as crystal seeds for crystallization.

[0003] During this process, the temperature of the entire liquid needs to be controlled. At the same time, in order to increase the crystallization rate, appropriate stirring can be performed so that the filtrate, alcohol and seed crystals can be fully mixed.

[0004] The existing temperature control method is often to set an interlayer or insulation layer on the outside of the crystallization tank, and control the temperature inside the crystallization tank by injecting a temperature regulating liquid into the interlayer.

[0035] A first aspect of the present invention, as Figure 1 and Figure 2 As shown, after filtering and sterilizing, fructose diphosphate sodium needs to be sent to the crystallization tank body 101 for crystallization. The crystallization tank body 101 of the present invention is specially designed. A sealed cover plate 103 is arranged on the top of the crystallization tank body 101, and a sealed base 102 is arranged on the bottom. The entire crystallization tank body 101 is in a completely sealed state except for the inlet and outlet pipes for the material in and out, so there is no need to worry about external pollution and various bacteria and microorganisms entering the crystallization tank body 101. The specific inlet and outlet pipes for the material in and out include a feed pipe 120, an alcohol feed pipe 121 and a discharge pipe 122. The feed pipe 120 and the alcohol feed pipe 121 are connected to the cover plate 103, and the discharge pipe 122 is connected to the bottom side wall of the crystallization tank body 101.

[0036] In addition, in order to better control the temperature in the crystallization tank body 101, a through vacuum chamber 112 is provided in the side wall of the crystallization tank body 101 and the cover plate 103, and the vacuum chamber 112 is also connected to the inner cavity of the base 102, and an air suction port 123 is also provided on the base 102. The vacuum chamber 112 and the inner cavity of the base 102 are evacuated through the air suction port 123, so that the crystallization tank body 101, the base 102 and the cover plate 103 themselves have good heat insulation performance, thereby ensuring a heat preservation effect, so that the temperature in the crystallization tank body 101 is easier to maintain stable.

[0037] The key point of the present invention is that Figure 2 and Figure 3 As shown, a plurality of stirring mechanisms arranged in the same row are arranged in the crystallization tank body 101, each stirring mechanism is composed of a middle connecting tube 107 and a plurality of temperature regulating tubes 108 fixedly connected to the connecting tube 107, and the connecting tube 107 rotates with the temperature regulating tube 108 to stir the solution in the crystallization tank body 101. The temperature regulating tube 108 is set to be U-shaped, and the upper and lower ends of the temperature regulating tube 108 are respectively connected to the upper and lower two adjacent connecting tubes 107. The connecting tubes 107 are fixedly connected in turn through the intermediate rod 109, the intermediate rod 109 is rotatably connected in the crystallization tank body 101, and the bottom end of the intermediate rod 109 is fixedly connected to the rotary mechanism in the base 102.

[0038] The stirring mechanism is driven by the flow of the temperature-adjusting liquid to drive the impeller 106 to rotate, thereby driving the stirring mechanism to rotate. Figure 5 and Figure 6 As shown, the impeller 106 connected between the temperature regulating liquid inlet pipe 104 and the stirring mechanism is located at the liquid outlet end of the temperature regulating liquid inlet pipe 104. When the temperature regulating liquid is sprayed out of the temperature regulating liquid inlet pipe 104, the impeller 106 is driven to rotate, and then the entire stirring mechanism is driven to rotate.

[0039] Specifically: an upper collector tube 105 is also rotatably connected to the top of the uppermost connecting tube 107, an impeller 106 is fixedly connected to the top of the uppermost connecting tube 107 and is located inside the upper collector tube 105, a temperature regulating liquid inlet pipe 104 is connected to the uppermost connecting tube 107 through the upper collector tube 105, and the upper collector tube 105 is also fixedly connected to the inner wall of the crystallization tank body 101 through a fixing rod 113.

[0040] Preferably, two temperature regulating liquid inlet pipes 104 are provided, and the two temperature regulating liquid inlet pipes 104 are arranged opposite to each other, and the liquid outlet ends of the two temperature regulating liquid inlet pipes 104 are also arranged opposite to each other and are respectively located on both sides of the impeller 106 .

[0041] Therefore, when the temperature-adjusting liquid is sprayed out from the two temperature-adjusting liquid inlet pipes 104, the impeller 106 will be subjected to force and rotate in the clockwise direction (the rotation direction of the impeller 106 is controlled by the setting position of the two temperature-adjusting liquid inlet pipes 104, so the rotation direction of the impeller 106 can be controlled by setting the positions of the two temperature-adjusting liquid inlet pipes 104 in advance). When the impeller 106 rotates in the clockwise direction, it will rotate with the entire stirring mechanism, that is, it will rotate with the connecting tube 107, the fixing rod 113 and the temperature-adjusting liquid inlet pipe 104. Since there are multiple temperature-adjusting liquid inlet pipes 104 and the temperature-adjusting tube 108 is set to be U-shaped, it has a good stirring effect. By replacing the temperature-adjusting liquid to make the liquid flow to drive the temperature-adjusting tube 108 to rotate, and then stir the solution in the crystallization tank body 101, not only the original power source for driving the stirring is saved, but also the equipment space is saved.

[0042] On the other hand, the temperature regulating tube 108 in the stirring mechanism also has the function of temperature control. Figure 3 , Figure 6 and Figure 7 As shown, the top of the uppermost connecting tube 107 is also rotatably connected to the upper manifold tube 105, and the temperature regulating liquid inlet tube 104 is connected to the uppermost connecting tube 107 through the upper manifold tube 105. The upper and lower ends of the temperature regulating tube 108 are respectively connected to the upper and lower adjacent connecting tubes 107 (i.e., fixedly connected and also connected to each other). Therefore, after the temperature regulating liquid enters the upper manifold tube 105 through the temperature regulating liquid inlet tube 104, it will flow to the uppermost connecting tube 107 below, and then flow to the temperature regulating tube 108 connected to the uppermost connecting tube 107, and then flow to the next connecting tube 107 through the temperature regulating tube 108, and so on, and finally flow into the lowermost connecting tube 107.

[0043] The bottom of the lowest connection tube 107 is also rotatably connected to the lower manifold tube 110, and the lowest connection tube 107 is also connected to the temperature regulating liquid outlet pipe 111 through the lower manifold tube 110. The lower manifold tube 110 is sleeved outside the middle rod 109 and rotatably connected thereto, and the lower manifold tube 110 is also fixedly connected to the bottom plate 114. Therefore, after the temperature regulating liquid flows into the lowest connection tube 107, it will finally flow out through the temperature regulating liquid outlet pipe 111, so that the temperature regulating liquid in the temperature regulating tube 108 will flow and be replaced regularly. The outer ends of the temperature regulating liquid inlet pipe 104 and the temperature regulating liquid outlet pipe 111 are connected to an external water pump and a temperature controller, which are used to pass the temperature regulating liquid into the temperature regulating tube 108 to control the temperature of the solution in the crystallization tank body 101;

[0044] The temperature regulating liquid in the temperature regulating tube 108 will flow and change regularly, which has a better temperature regulating effect. The multiple curved temperature regulating tubes 108 are designed to serve as stirring elements, which not only have a stirring effect, but also make the temperature regulating tube 108 more fully contact with the solution in the crystallization tank body 101, which has a better temperature regulating effect.

[0045] On the other hand, Figure 2 and Figure 4 As shown, a slewing mechanism is provided in the base 102, and the bottom end of the intermediate rod 109 is fixedly connected to the slewing mechanism in the base 102, and can be driven to rotate by the slewing mechanism. The slewing mechanism includes a central connecting column 115, an energy storage cylinder 116, an energy storage slider 17 and a cable 118. The central connecting column 115 is rotatably connected to the center of the bottom plate of the base 102, and the central connecting column 115 is fixedly connected to the intermediate rod 109. A plurality of energy storage cylinders 116 are provided and fixedly connected to the side wall of the base 102. An energy storage slider 17 is slidably connected in each energy storage cylinder 116, and the energy storage slider 17 is connected to the central connecting column 115 through the cable 118. An energy storage spring 119 is also provided in the energy storage cylinder 116, and the two ends of the energy storage spring 119 are respectively connected to the side wall of the base 102 and the energy storage slider 17.

[0046] The rotating mechanism provided in the base 102 acts as a power source during the period when the temperature regulating liquid is not replaced and does not flow, so that the temperature regulating tube 108 continues to rotate and the stirring direction of the temperature regulating tube 108 is continuously reversed to enhance the stirring effect.

[0047] Another purpose of the design of this mechanism is to save the amount of temperature-control liquid used. After the temperature-control liquid is pumped into the temperature-control tube 108 by the external water pump, the original temperature-control liquid in the temperature-control tube 108 is replaced, and then the external water pump stops working. The newly pumped temperature-control liquid is allowed to remain in the temperature-control tube 108 for a longer period of time to ensure a more complete temperature exchange, thereby achieving the effect of saving temperature-control liquid. However, because the temperature-control liquid does not flow all the time, it cannot drive the entire stirring mechanism to rotate in the clockwise direction all the time. Instead, the entire stirring mechanism can be driven to rotate in the clockwise direction only when the external water pump delivers the temperature-control liquid.

[0048] During this process, the clockwise rotation of the stirring mechanism will cause the central connecting column 115 to rotate, and then the cable 118 will be wound around the central connecting column 115. During the winding process of the cable 118, the energy storage slider 17 will slide out, and then the energy storage spring 119 will be stretched to store energy. After the external water pump finishes delivering the temperature-regulating liquid, the stirring mechanism loses power and inertia, and the energy storage spring 119 will release the stored energy, and drive the central connecting column 115 to rotate counterclockwise through the energy storage slider 17 and the cable 118, and then drive the stirring mechanism to rotate counterclockwise. Similarly, after the stirring mechanism rotates counterclockwise until the inertia disappears, it will rotate clockwise again until it stops completely. After the stirring mechanism stops completely, the external water pump restarts to start a new round of replacing the temperature-regulating liquid, and also starts a new round of stirring work of the stirring mechanism.

[0049] Therefore, the rotating mechanism provided in the base 102 acts as a power source when the temperature regulating liquid is not replaced and does not flow, so that the temperature regulating tube 108 continues to rotate and the stirring direction of the temperature regulating tube 108 is continuously reversed to enhance the stirring effect. DETAILED DESCRIPTION

[0050] After filtering and sterilizing sodium fructose diphosphate, the filtrate is pressed into the crystallization tank body 101 through the feed pipe 120 with sterilized compressed air, and then an ethanol solution with a mass fraction of 95% is added to the crystallization tank body 101 through the alcohol inlet pipe 121, and then qualified sterile sodium fructose diphosphate raw materials are added as crystal seeds to carry out crystallization.

[0051] After the above preparations are completed, the external water pump starts to work and pumps the temperature-adjusting liquid into the temperature-adjusting tube 108 through the temperature-adjusting liquid inlet pipe 104. During this process, the impeller 106 will be forced to rotate clockwise, and then the entire stirring mechanism will rotate, that is, the connecting tube 107, the fixing rod 113 and the temperature-adjusting liquid inlet pipe 104 will rotate. The temperature-adjusting liquid inlet pipe 104 is provided with multiple roots, and the temperature-adjusting tube 108 is set to be U-shaped, so it has a good stirring effect. By replacing the temperature-adjusting liquid to make the liquid flow to drive the temperature-adjusting tube 108 to rotate, and then stir the solution in the crystallization tank 101, not only the original power source for driving the stirring is saved, but also the equipment space is saved.

[0052] Moreover, the clockwise rotation of the stirring mechanism will cause the central connecting column 115 to rotate, thereby causing the cable 118 to be wound around the central connecting column 115. During the winding process, the cable 118 causes the energy storage slider 17 to slide out, thereby stretching the energy storage spring 119 to store energy. After the external water pump finishes delivering the temperature control liquid, the pumped temperature control liquid is retained in the temperature control tube 108 for a period of time to ensure a more complete temperature exchange, thereby achieving the effect of saving the temperature control liquid.

[0053] Therefore, after the stirring mechanism loses power and inertia, the energy storage spring 119 will release the stored energy, and drive the central connecting column 115 to rotate counterclockwise through the energy storage slider 17 and the cable 118, thereby driving the stirring mechanism to rotate counterclockwise. Similarly, after the stirring mechanism rotates counterclockwise until the inertia disappears, it will rotate clockwise again until it stops completely. After the stirring mechanism stops completely, the external water pump restarts to start a new round of replacement of the temperature control liquid, and also starts a new round of stirring work of the stirring mechanism. Therefore, the rotating mechanism is arranged in the base 102 to act as a power source during the period when the temperature control liquid is not replaced and is not flowing, so that the temperature control tube 108 can still keep rotating, and at the same time, the stirring direction of the temperature control tube 108 is constantly reversed to enhance the stirring effect.

[0054] After the temperature-adjusting liquid enters the upper manifold tube 105 through the temperature-adjusting liquid inlet tube 104, it flows to the uppermost connecting tube 107 below, and then flows to the temperature-adjusting tube 108 connected to the uppermost connecting tube 107, and flows to the next connecting tube 107 through the temperature-adjusting tube 108, and so on, and finally flows into the lowermost connecting tube 107. After the temperature-adjusting liquid flows to the lowermost connecting tube 107, it finally flows out through the temperature-adjusting liquid outlet tube 111, so that the temperature-adjusting liquid in the temperature-adjusting tube 108 can be regularly circulated and replaced.

[0055] After the final crystallization is completed, the waste gas and waste liquid are discharged, and the crystals are then centrifuged and dried, sieved, weighed, and finally packaged.

[0056] Based on the above, the present invention designs a plurality of curved thermostatic tubes 108 to act as stirring members, which not only play a stirring role, but also make the thermostatic tube 108 more fully contact with the solution in the crystallization tank body 101, thereby playing a better temperature control role. The thermostatic liquid in the thermostatic tube 108 will flow and change regularly, which has a better temperature control effect. At the same time, the thermostatic liquid is replaced to make the liquid flow to drive the thermostatic tube 108 to rotate, thereby stirring the solution in the crystallization tank body 101, which not only saves the original power source for driving stirring, but also saves equipment space. The rotary mechanism is arranged in the base 102 to act as a power source during the period when the thermostatic liquid is not replaced and does not flow, so that the thermostatic tube 108 can still keep rotating, and at the same time, the stirring direction of the thermostatic tube 108 is constantly reversed, thereby enhancing the stirring effect.
