Description

Technical Field

[0001] The invention relates to the technical field of protein concentration, in particular to an evaporation and concentration device based on protein concentrate. Background Art

[0002] Evaporation and concentration of protein concentrate is a process to increase protein concentration, which is commonly used in the food, pharmaceutical and biotechnology industries. Evaporation and concentration of protein concentrate helps to reduce the volume of liquid, thereby reducing transportation and storage costs, while increasing the concentration of effective protein ingredients in the final use of the product. In addition, the concentrated protein liquid is more convenient for further processing or formulation, especially in the food, pharmaceutical and biotechnology industries, which can improve the nutritional value and functionality of the product. Through evaporation and concentration, a large amount of protein solution can be effectively converted into a high-concentration protein product to meet the needs of different applications.

[0003] In the process of concentrating the existing protein concentrate, the water contained in the protein concentrate will be evaporated into water vapor, and when flowing out of the evaporation tube, the concentrated protein concentrate will fall downward under the action of gravity, while the water vapor will float above and finally be discharged outward. In this process, since the steam will surround the top of the concentrated protein concentrate, as the amount of concentrated protein concentrate increases, the space on the top will gradually decrease, that is, the space for discharging water vapor will become smaller, so that the protein concentrate that does not have time to fall will be discharged along with the water vapor, thereby causing a waste of raw materials.

[0034] A rectangular frame 1 34 and a rectangular frame 2 35 are fixedly installed inside the feed hopper 5, and a fixed pipe 36 is fixedly connected between the rectangular frame 1 34 and the rectangular frame 2 35. A plurality of heat exchange tubes 1 37 and heat exchange tubes 2 38 are staggeredly connected inside the rectangular frame 1 34 and the rectangular frame 2 35. A steam exhaust pipe 8 is fixedly connected to the surface of one side of the rectangular frame 1 34, and the other end of the steam exhaust pipe 8 is fixedly connected to the outer surface of the storage tank 2. A connecting pipe 1 9 is fixedly connected to the other end of the rectangular frame 2 35, and one end of the connecting pipe 1 9 is fixedly connected to a rectangular tube 10. Both ends of the bottom surface of the rectangular tube 10 are fixedly connected to a connecting pipe 2 11, and one end of the connecting pipe 2 11 is fixedly connected to the outer surface of the connecting pipe 3 15. The top surface of the feed hopper 5 is fixedly connected to A mounting frame 40 is provided, wherein a motor 39 is fixedly installed inside the mounting frame 40, an output end of the motor 39 is fixedly connected to a fixed shaft 41, one end of the fixed shaft 41 extends to the inside of the feed tank 4, and one end of the fixed shaft 41 extending to the inside of the feed tank 4 is fixedly connected to a protrusion 43, the diameter of the protrusion 43 is larger than the opening diameter of the connecting tube 6, a spiral blade 42 is fixedly installed on the outer surface of the fixed shaft 41 located inside the connecting tube 6, wherein a fixed mounting ring 23 is fixedly installed on the outer surface of the rotating shaft 22, and a plurality of paddles 24 are fixedly installed on the outer surface of the fixed mounting ring 23, and the bottom surface of the paddle 24 is in contact with the top surface of the mounting plate 19, so as to facilitate scraping the protein liquid into each evaporation tube 21 for evaporation.

[0035] During operation, in the process of concentrating the protein solution, the protein solution that needs to be concentrated is first added to the inside of the feed hopper 5, and then the fixed shaft 41 is driven to rotate inside the feed hopper 5 by controlling the motor 39, wherein the outer wall of the spiral blade 42 is fitted with the inner wall of the connecting pipe 6. By so arranging, it is possible to make it possible that during the counterclockwise rotation of the fixed shaft 41, no protein solution enters the inside of the feed tank 4 through the connecting pipe 6, and when the motor 39 rotates clockwise, the protein solution inside the feed hopper 5 can be driven to enter the inside of the feed tank 4. When the protein solution enters the inside of the feed tank 4, it will first be blocked by the bump 43. The protein liquid is scattered on the top surface of the mounting plate 19, and when the fixed shaft 41 rotates, since the bottom surface of the protrusion 43 is fixedly connected to the top of the rotating shaft 22, the fixed mounting ring 23 can be driven to rotate, thereby driving the fixed mounting ring 23 and the paddle 24 to rotate on the top surface of the mounting plate 19, and the protein liquid on the top surface of the mounting plate 19 is evenly scraped to the inside of each evaporation tube 21. When the protein liquid enters the inside of the evaporation tube 21, the water in the protein liquid is converted into water vapor through high-temperature evaporation, and falls downward together with the concentrated liquid, the concentrated liquid sinks to the bottom, and the water vapor floats upward, thereby achieving the concentration of the protein liquid.

[0036] In the process, the water vapor for concentrating in the outside world is transported to the inside of the evaporation tank 3 by the steam delivery pipe 7, and the evaporation tube 21 inside the evaporation tank 3 is heated, so that after the protein liquid enters the inside of the evaporation tube 21, it is used for the heating concentration of the protein liquid, when the water vapor formed by moisture in the protein liquid is scattered in the inside of the storage tank 2, it can enter the inside of the surge tank 12 by the discharge pipe 13, and a small amount of protein liquid will still remain in the protein liquid water vapor evaporated, therefore when the water vapor in the protein liquid enters the inside of the surge tank 12 by the discharge pipe 13, heat exchange is carried out with the tank body 45 inside the surge tank 12, It is cooled, and the residual protein liquid is condensed in the buffer tank 12, while the water vapor is sucked into the compression fan 14 through the connecting pipe 3 15, and after compression and heating, it is discharged into the installation groove 17 through the compression delivery pipe 16 again, and finally enters the evaporation tank 3 together with the external steam, and is used for the concentration operation of the protein liquid, thereby achieving the purpose of re-extracting the water vapor evaporated from the protein liquid on the one hand, and re-utilizing the water vapor evaporated from the protein liquid on the other hand, achieving the purpose of energy saving, thereby greatly increasing the practicality of the overall device.

[0037] After the protein liquid is added to the interior of the feed hopper 5, it can enter the interior of the evaporator 3 through the steam delivery pipe 7 through the external heating steam, then be discharged through the steam discharge pipe 8, and finally enter the interior of the rectangular frame 1 34 and the rectangular frame 2 35, and finally enter the interior of the heat exchange tube 1 37 and the heat exchange tube 2 38, to preheat the protein liquid in the feed hopper 5, thereby increasing the subsequent evaporation effect of the protein liquid in the feed hopper 5, and avoiding the problem that the protein liquid at room temperature is directly heated to the evaporation temperature, which may easily cause the protein liquid to be damaged.

[0038] A movable plug 32 is movably inserted inside the bottom plate 1, and a space adjustment component 18 is arranged below the movable plug 32. The space adjustment component 18 is arranged to expand the space inside the storage tank 2;

[0039] The space adjustment component 18 includes a positioning frame 1801, and a mounting groove 17 is formed through the outer surface of the storage tank 2. The positioning frame 1801 is fixedly installed inside the mounting groove 17. A mounting column 1802 is fixedly inserted inside the positioning frame 1801, and a ring 1803 is movably sleeved on the outer surface of the mounting column 1802. There are two rings 1803, and the bottom surfaces of the two rings 1803 are fixedly installed with extension plates 1804. A spring 1805 is fixedly connected between the two extension plates 1804. A support 1806 is fixedly installed on the top surface of the ring 1803 and the bottom surface of the movable plug 32, and an inclined plate 1807 is movably connected between the two supports 1806.

[0040] During operation, as the protein liquid is more and more concentrated, more and more concentrated liquid falls into the storage tank 2, causing the movable plug 32 to bear more and more gravity. As the concentrated liquid continues to increase, the movable plug 32 will be pressed downward, causing the movable plug 32 to move downward inside the storage tank 2, thereby allowing the concentrated liquid level above the movable plug 32 to always form a sufficient gap with the bottom surface of the mounting plate 20 for the discharge of water vapor in the protein liquid, thereby reducing the amount of protein liquid taken away by water vapor, thereby achieving the purpose of not reducing the gap between the movable plug 32 and the mounting plate 20 due to the increase of the concentrated liquid level.

[0041] A touch switch 1812 is fixedly installed on the outer surface of the ring 1803 , baffles 1808 are fixedly installed on both ends of the positioning frame 1801 , and the touch switch 1812 is electrically connected to the motor 39 .

[0042] During operation, when the movable plug 32 moves downward inside the storage tank 2, the collar 1803 on the outer surface of the mounting column 1802 can move toward both sides on the outer surface of the mounting column 1802. During the movement, when the touch switch 1812 installed on one side of the collar 1803 contacts the baffle 1808, the motor 39 can be controlled to rotate clockwise. When the motor 39 rotates clockwise, the spiral blade 42 can be driven to rotate clockwise inside the connecting pipe 6, that is, no more material is discharged. With the rotation of the spiral blade 42, the protein liquid inside the feed hopper 5 can be flipped upward to prevent the protein liquid from precipitating inside the feed hopper 5 and affecting the subsequent evaporation and concentration operations. In addition, by observing the contact between the two, it can be judged that the concentrated liquid on the top of the movable plug 32 is full and can be taken out in time.

[0043] The outer surface of the mounting column 1802 is provided with a scale groove 1811 , through which the storage amount of the concentrated liquid inside the storage tank 2 can be observed more intuitively.

[0044] The outer surface of the storage tank 2 is provided with a knocking component 33, and the knocking component 33 is provided to accelerate the falling of the protein concentrate;

[0045] The knocking assembly 33 includes a fixed sleeve 3301, a positioning seat 3302 is fixedly installed on the outer surface of the fixed sleeve 3301, a movable plate 3303 is movably installed inside the positioning seat 3302, a spring 2 3308 is fixedly connected between the movable plate 3303 and the outer surface of the storage tank 2, a connecting rod 3304 is fixedly installed on one side surface of the movable plate 3303, a knocking plate 3305 is fixedly installed on one end of the connecting rod 3304, and a base 3306 is fixedly installed on the other end of the movable plate 3303 , plug-in plates 3307 are fixedly installed at both ends of the bottom surface of the base 3306, and a parallel plate 1809 is fixedly installed on the outer surface of the ring 1803. An arc groove 1810 is opened on the top surface of the parallel plate 1809. The bottom end of the plug-in plate 3307 is an arc-shaped structure, and the plug-in plate 3307 is plugged into the inside of the arc groove 1810. When the concentrated liquid above the movable plug 32 is taken out, the movable plug 32 will return to its original position under the resetting action of the spring 1805, wherein the connecting rod 3304 is flexibly set.

[0046] During operation, when the sleeve 1803 moves toward both sides on the outer surface of the mounting column 1802, it can drive the parallel plate 1809 to move toward both sides of the mounting column 1802. During the movement, it can also drive the parallel plate 1809 to move synchronously. At this time, the connecting rod 3304 can be slightly contracted, causing the parallel plate 1809 to move toward both sides of the mounting column 1802. When the concentrated liquid inside the movable plug 32 is taken out, the two sleeves 1803 can be driven to move toward each other under the action of the spring 1805, so that under the action of the plug plate 3307 and the arc groove 1810, the movable plate 3303 can be driven to knock on the outer surface of the storage tank 2 through the connecting rod 3304 and the knocking plate 3305, so that the concentrated liquid adhering to the inner wall of the storage tank 2 can fall quickly, and can be discharged together with the concentrated liquid on the top of the movable plug 32, thereby achieving a more efficient discharging operation.

[0047] A rotating shaft 22 and a rotating shaft 28 are rotatably installed inside the mounting plate 19 and the mounting plate 20 respectively, a threaded rod 25 is fixedly connected between the rotating shaft 22 and the rotating shaft 28, a threaded sleeve 26 is threadedly sleeved on the outer surface of the threaded rod 25, a scraper 27 is fixedly installed on the outer surface of the threaded sleeve 26, the number of the scrapers 27 corresponds to the number of the evaporation tubes 21, the scrapers 27 are movably sleeved on the outer surface of the evaporation tubes 21, and each scraper 27 is fixedly connected.

[0048] During operation, when the motor 39 rotates clockwise, the threaded sleeve 26 and the scraper 27 can be driven to move upward under the action of the thread. During the movement, the scale on the outer surface of the evaporator tube 21 can be scraped off, and when the threaded sleeve 26 moves to the bottom surface of the mounting plate 19, the threaded sleeve 26 is located on the outer surface of the rotating shaft 12, that is, it is movably sleeved on the outer surface of the rotating shaft 12 and will not move upward. Conversely, when the motor 39 rotates counterclockwise, the threaded sleeve 26 can be driven to move downward. When it is located on the outer surface of the mounting plate 20, since the outer surface of the mounting plate 20 is fixedly installed with a force-sensitive switch, when the threaded sleeve 26 presses the force-sensitive switch, the motor 39 can be immediately controlled to rotate in the opposite direction, thereby achieving the purpose of intermittent material unloading. The threaded sleeve 26 is located on the outer surface of the rotating shaft 28 and will not move downward, thereby achieving the purpose of cleaning the scale on the outer surface of the evaporator tube 21, and preventing the problem of scale adhering to the outer surface of the evaporator tube 21 resulting in poor evaporation effect.

[0049] A circular frame 44 is fixedly installed inside the buffer tank 12, and a tank body 45 is fixedly installed inside the circular frame 44. A feed pipe 46 is fixedly connected to the top of the tank body 45. The other end of the feed pipe 46 is fixedly connected to the outer surface of the steam delivery pipe 7. A one-way valve 47 is fixedly installed on the outer surface of the feed pipe 46.

[0050] During operation, when the water vapor evaporated from the concentrated liquid enters the buffer tank 12 through the discharge pipe 13, heat exchange is performed with the tank body 45, that is, the tank body 45 is heated by the heat of the water vapor in the concentrated liquid entering the buffer tank 12, so that the acidic solution in the tank body 45 evaporates to form steam, and enters the steam delivery pipe 7 through the feed pipe 46, and enters the evaporation tank 3 together with the heated steam in the steam delivery pipe 7. The acidic steam contacts the scale on the outer surface of the evaporation tube 21 and dissolves the scale, thereby further improving the cleaning effect of the scale on the outer surface of the evaporation tube 21.

[0051] The second rotating shaft 28 is located on the bottom surface of the second mounting plate 20 and is fixedly sleeved with a second fixed mounting ring 30 . The outer surface of the second fixed mounting ring 30 is fixedly connected with a plurality of fan blades 31 . The height of the second fixed mounting ring 30 and the fan blades 31 is level with the discharge pipe 13 .

[0052] During operation, when the rotating shaft 28 rotates, it can drive the fixed mounting ring 2 30 and the fan blades 31 to rotate, so that the evaporated steam in the protein liquid can be more effectively transported to the inside of the buffer tank 12 through the discharge pipe 13, thereby improving the steam transportation effect.

[0053] Specifically, the working process or working principle of the evaporation concentration equipment based on protein concentrate is as follows: when in use, the protein solution to be concentrated is first added to the inside of the feed hopper 5, and the external heating steam enters the inside of the evaporation tank 3 through the steam delivery pipe 7, and then is discharged through the steam discharge pipe 8, and finally enters the inside of the rectangular frame 1 34 and the rectangular frame 2 35, and finally enters the inside of the heat exchange tube 1 37 and the heat exchange tube 2 38, and the protein solution inside the feed hopper 5 is preheated, thereby increasing the subsequent evaporation effect of the protein solution inside the feed hopper 5, and then the fixed shaft 41 is driven to rotate inside the feed hopper 5 by controlling the motor 39, wherein the outer wall of the spiral blade 42 is fitted with the inner wall of the connecting pipe 6, and by such an arrangement, it can be made that in the process of the fixed shaft 41 rotating counterclockwise, no protein solution will enter the feed tank 4 through the connecting pipe 6. Inside, and when the motor 39 rotates clockwise, the protein liquid inside the feed hopper 5 can be driven to enter the inside of the feed tank 4. When the protein liquid enters the inside of the feed tank 4, the protein liquid will first be scattered on the top surface of the installation disk 19 by the obstruction of the projection 43, and when the fixed shaft 41 rotates, since the bottom surface of the projection 43 is fixedly connected with the top of the rotating shaft 22, the fixed installation ring 23 can be driven to rotate, thereby driving the fixed installation ring 23 and the paddle 24 to rotate on the top surface of the installation disk 19, and the protein liquid on the top surface of the installation disk 19 is evenly scraped off to the inside of each evaporation tube 21. When the protein liquid enters the inside of the evaporation tube 21, after high-temperature evaporation, the moisture in the protein liquid becomes water vapor, and falls downwards together with the concentrated solution, the concentrated solution sinks to the bottom, and the water vapor floats upwards, thereby realizing the concentration of the protein liquid;

[0054] As the protein solution is concentrated more and more, more and more concentrated solution falls into the storage tank 2, so that the gravity borne by the movable plug 32 is getting larger and larger. As the concentrated solution continues to increase, the movable plug 32 is pressed downward, so that the movable plug 32 moves downward inside the storage tank 2, so that the liquid level of the concentrated solution above the movable plug 32 can always form a sufficient distance with the bottom surface of the mounting plate 20 for the discharge of water vapor in the protein solution;

[0055] During the movement of the sleeve 1803, the parallel plate 1809 can also be driven to move synchronously. At this time, the connecting rod 3304 can be slightly contracted, causing the parallel plate 1809 to move toward both sides of the mounting column 1802. When the concentrated liquid inside the movable plug 32 is taken out, the two sleeves 1803 can be driven to move toward each other under the action of the spring 1805. Therefore, under the action of the plug plate 3307 and the arc groove 1810, the movable plate 3303 can be driven to knock on the outer surface of the storage tank 2 through the connecting rod 3304 and the knocking plate 3305, so that the concentrated liquid adhering to the inner wall of the storage tank 2 can fall quickly, which is convenient for subsequent discharging operations.
