Abstract
Description
Technical Field
[0001] This invention relates to the technical field of flash drying apparatus for composite amino acid chelates, specifically to a flash drying apparatus for composite amino acid chelates. Background Technology
[0002] Amino acid chelates are a class of organic mineral salts formed by the coordination of amino acids with metal ions (such as iron, copper, zinc, and manganese). They possess significant advantages such as high bioavailability, good chemical stability, and excellent palatability. In the industrial production of amino acid chelates, drying is one of the key processes, as its effectiveness directly affects the final quality, stability, and application performance of the product.
[0003] The drying process of amino acid chelates has the following technical characteristics: (1) High heat sensitivity: Amino acids are prone to denaturation and decomposition at high temperatures, resulting in reduced product activity; (2) High water content: The water content of the material after liquid phase reaction is usually 40%-70%, requiring a large amount of heat energy to remove water; (3) High viscosity: The viscosity of amino acid chelate solution is high, making it easy to stick to the wall and clump; (4) Strict particle size requirements: The product needs to achieve a specific particle size distribution to meet the needs of subsequent applications.
[0004] Currently, the industry primarily uses traditional flash dryers and spray dryers for drying complex amino acid chelates. While spray dryers can achieve rapid drying, they have high energy consumption and operating costs. Furthermore, for highly viscous complex amino acid chelates, uneven atomization and severe material adhesion to the walls are common problems, increasing cleaning difficulty and causing material waste and product contamination. Traditional flash dryers mainly rely on continuous hot air conveying for material drying, which has the following significant drawbacks: 1. Uneven hot air temperature distribution can easily lead to localized high-temperature areas, causing thermal denaturation of some materials, while localized low-temperature areas can result in incomplete drying of the materials. 2. The residence time of materials in the drying tube is difficult to control precisely. Too long a residence time can lead to the destruction of nutrients, while too short a residence time can not achieve the qualified moisture content. 3. The airflow stability generated by continuous hot air is poor, the heat and mass transfer efficiency between the gas and solid phases is low, and the material is prone to sticking to the inner wall of the drying tube and agglomerating, which not only affects the drying effect, but may also cause pipeline blockage and affect the continuous and stable operation of the equipment. Summary of the Invention
[0005] The purpose of this invention is to provide a flash drying apparatus for composite amino acid chelates to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a flash drying device for composite amino acid chelates, comprising a centrifugal fan and an air purification box, wherein the outlet of the centrifugal fan is connected to the air purification box, the outlet of the air purification box is connected to a fixed box, an electric heating tube is fixed at equal angles inside the fixed box, a screw feeder is provided on the side of the fixed box, a hopper is fixed on the screw feeder, the outlet of the screw feeder is connected to a drying pipe, a driving structure is installed inside the fixed box to realize the pulse drying effect of the material, one end of the drying pipe is connected to a connecting pipe, and the other end of the connecting pipe is connected to a cyclone separator along the tangential direction, and a bag filter is provided on the side of the cyclone separator.
[0007] Preferably, the drying tube has a gradually changing diameter structure, with the upper diameter being 10%-20% larger than the lower diameter. The inner wall of the drying tube is mirror-polished and coated with a polytetrafluoroethylene (PTFE) anti-stick coating. The drying tube is also covered with an insulation layer. The gradually changing diameter structure of the drying tube reduces the airflow velocity and extends the drying time. The PTFE anti-stick coating effectively reduces the probability of material adhesion.
[0008] Preferably, temperature sensors are fixed at equal intervals inside the drying tube, and one end of the drying tube is fixed to the support rod, while the other end of the support rod is fixed to the arc panel. At the same time, an inclined material distribution plate is provided above the arc panel. The material distribution plate is fixed inside the drying tube, and the material distribution plate has leakage ports opened at equal angles. Through the function of the temperature sensors, temperature detection can be realized. Through the function of the arc panel and the material distribution plate, the movement path of the material in the drying tube can be controlled, thereby further prolonging the drying process and ensuring the drying effect of the material.
[0009] Preferably, a rotating shaft is connected to the bearing on the arc panel, and an elastic metal strip is fixed on the rotating shaft. The elastic metal strip and the metal ball are fixed to each other, and the metal ball and the protrusion collide to achieve a knocking effect. The protrusion is fixed at an equal angle inside the drying tube. The rotating shaft drives the elastic metal strip and the metal ball to rotate. Combined with the knocking effect of the metal ball and the protrusion, the drying tube can generate micro-vibration, thereby further preventing the material from sticking to the inner wall of the drying tube.
[0010] Preferably, the drive structure includes a motor fixed to the lower end face of the fixed box, and a drive gear is fixed to the output end of the motor. The drive gear meshes with the driven gear to achieve transmission. At the same time, the driven gear is fixed to the hollow tube. The hollow tube is connected to the fixed box and the drying tube by bearings, and a baffle is fixed to the hollow tube. By driving the drive gear to rotate through the motor, and with the meshing transmission between the drive gear and the driven gear, the hollow tube and the baffle can rotate synchronously. Through the action of the baffle, the air can be turbulent, thereby ensuring the uniformity of air temperature and thus ensuring the drying effect of the subsequent materials.
[0011] Preferably, the hollow tube and the disc are slidably connected, and the disc is fixed on the output end of the motor. A limit ring is fixed on the disc, and the limit ring is slidably connected to the hollow tube. The disc is also provided with a through hole. The motor drives the disc to rotate, which in turn drives the through hole to rotate synchronously. Through the separation and cooperation between the through hole and the hollow tube, intermittent high-temperature air can be delivered, thus providing a basic guarantee for the realization of pulse drying of materials.
[0012] Preferably, a centrifugal disc is fixed on the hollow tube and is placed inside the drying tube. A striking block is also fixed on the centrifugal disc at an equal angle. Through the rotation of the centrifugal disc and the striking block, the material can be centrifugally dispersed and the clumped material can be struck and dispersed to avoid the material from clumping together and affecting the drying effect.
[0013] Preferably, a cylinder is fixed on the centrifugal disc, and the cylinder has chip discharge ports at equal angles. A crossbar is also fixed on the cylinder, and the crossbar is fixed to the spinning cone block. A guide plate fixed inside the cylinder is provided on the lower side of the spinning cone block, and the guide plate is installed at an angle. The crossbar is fixed to the rotating shaft. Through the above structure, the hollow tube can be protected, effectively preventing the material from falling through the hollow tube due to the pulse gap during the pulse drying process, which would affect the normal operation of the device.
[0014] Preferably, a fixed rod is fixed inside the connecting pipe, and a sliding rod is slidably connected to the fixed rod. One end of the sliding rod is fixed with a windward plate facing the drying pipe, and a spring is fixed between the windward plate and the fixed rod. The other end of the sliding rod is fixed with a mounting plate, and the mounting plate is rotatably connected to one end of the connecting rod. The other end of the connecting rod is rotatably connected to a baffle plate, and the baffle plate is slidably connected to the connecting pipe and the cyclone separator. Through the action of the windward plate, the airflow entering the cyclone separator can be detected. Combined with the adjustment of the distance between the two baffle plates, the stability of the wind speed entering the cyclone separator can be ensured.
[0015] Preferably, a discharge valve is installed below the cyclone separator, and an exhaust port is installed on the upper side of the cyclone separator. The exhaust port is connected to one end of a connecting pipe, and the other end of the connecting pipe is connected to a bag filter. Through the action of the bag filter, the exhaust gas can be treated.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This composite amino acid chelate flash drying device achieves rapid drying of materials through rapid heat and mass transfer via pulsed airflow, shortens the residence time of materials in high-temperature environments, avoids thermal denaturation of amino acids, and adopts a coupling structure of pulsed airflow and cyclone separation to improve thermal energy utilization efficiency and reduce drying energy consumption. Through special airflow distribution design and pulse action, it prevents high-viscosity materials from adhering to the inner wall of the equipment, effectively ensuring the drying effect of the materials. 2. This flash drying device for composite amino acid chelates uses a rotating disc to separate or engage the through-holes with the hollow tube, enabling pulse drying. The pulsed airflow generates a strong turbulent effect, significantly enhancing the heat and mass transfer efficiency between the gas and solid phases. Simultaneously, the periodic acceleration and deceleration of the airflow causes the material particles to vibrate and collide with each other within the tube. This ensures rapid evaporation of moisture while effectively shortening the continuous residence time of the material in the high-temperature zone. This prevents the composite amino acid chelates from denaturing, deactivating, or discoloring due to prolonged high-temperature heating, maximizing the preservation of the product's biological activity and effective components, and improving the product's quality pass rate. 3. In this flash drying device for composite amino acid chelates, after the material enters the drying tube, centrifugal force generated by the high-speed rotating centrifugal disc quickly disperses the material to the surrounding walls of the tube. At the same time, the impact blocks distributed at equal angles on the centrifugal disc continuously break up any agglomerated or sticky materials, thus preventing incomplete drying caused by material clumping at the source. The drying tube has a mirror-polished inner wall and is coated with a polytetrafluoroethylene anti-stick coating. Combined with pulsed airflow disturbance and micro-vibration of the tube wall, the conditions for material adhesion to the tube wall are doubly blocked, completely solving common industry problems such as wall adhesion, scaling, blockage, and agglomeration during the drying process of composite amino acid chelates. Frequent shutdowns for cleaning are not required, ensuring continuous and stable operation of the equipment. 4. This flash drying device for composite amino acid chelates addresses the problem that interruptions in the pulse air supply can easily lead to material backflow and blockage of the hollow tube. By setting a spindle-shaped block and an inclined guide plate inside the cylinder to work together to guide the flow, the material falling during the pulse interval is quickly returned to the main cavity of the drying tube through the chip discharge port under the guidance of the rotational centrifugal force and the flow guiding structure. This completely avoids the problem of material backflow into the hollow tube and hot air channel, causing blockage and shutdown. The stability of the device operation is greatly improved and the failure rate is significantly reduced. 5. This flash drying device for composite amino acid chelates features a drying tube with a gradually increasing diameter, smaller at the bottom and larger at the top. The upper diameter is 10%-20% larger than the lower diameter. Combined with the multi-stage flow guidance effect of the arc panel and inclined distribution plate inside the tube, it effectively reduces the flow velocity of the material rising with the airflow, prolonging the effective residence time of the material in the drying tube. This ensures thorough drying without high-temperature denaturation of the material, thereby reducing the final moisture content of the product. Simultaneously, temperature sensors are evenly distributed inside the tube to monitor temperature changes in real time, enabling precise control of the drying temperature and further ensuring a stable and controllable drying process. 6. This flash drying device for composite amino acid chelates addresses the issue of back-end airflow fluctuations caused by front-end pulsed airflow by incorporating an adaptive flow stabilization mechanism consisting of a wind-facing plate, spring, slide bar, and baffles within the connecting pipe. When airflow velocity changes, the wind pressure pushes the wind-facing plate to shift, and the spring's reset action and linkage transmission automatically adjust the baffle spacing, stabilizing the airflow velocity entering the cyclone separator in real time. This eliminates the interference of front-end pulsed airflow and fan pressure fluctuations on the gas-solid separation effect, ensuring efficient separation and sedimentation of the dried material, which is then stably discharged through the discharge valve, significantly improving product yield. The separated exhaust gas is then deeply purified by a bag filter before being discharged, completely avoiding dust pollution and meeting environmental protection production requirements.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please see Figures 1-8 This invention provides a technical solution: a flash drying device for composite amino acid chelates, comprising a centrifugal fan 1 and an air purification box 2. The air outlet of the centrifugal fan 1 is connected to the air purification box 2, and the air outlet of the air purification box 2 is connected to a fixed box 3. An electric heating tube 301 is fixed at equal angles inside the fixed box 3. A screw feeder 4 is provided on the side of the fixed box 3, and a hopper 5 is fixed on the screw feeder 4. The discharge port of the screw feeder 4 is connected to a drying pipe 6. A drive structure 7 is installed inside the fixed box 3 to realize the pulse drying effect of the material. One end of the drying pipe 6 is connected to a connecting pipe 8, and the other end of the connecting pipe 8 is connected to a cyclone separator 9 along the tangential direction. A bag filter 11 is provided on the side of the cyclone separator 9.
[0021] When using this composite amino acid chelate flash drying device, such as Figures 1-8As shown, when using this device, the material to be dried is placed in the hopper 5, and with the action of the screw feeder 4, the material can be fed into the drying tube 6 at a uniform speed for subsequent drying. During the material drying process, the centrifugal fan 1 is started to send outside air into the air purification box 2. The air purification box 2 is equipped with a primary filter and a high-efficiency air filter to achieve air purification. The purified air enters the fixed box 3 and is heated by the electric heating tube 301 to ensure that the air temperature is between 120℃ and 200℃ for subsequent material drying. The drive structure 7 includes a motor 701 fixed to the lower end face of the fixed box 3, and a drive gear 702 fixed to the output end of the motor 701. The drive gear 702 meshes with the driven gear 703 to achieve transmission. The driven gear 703 is fixed to the hollow tube 704. The hollow tube 704 is connected to the fixed box 3 and the drying tube 6 by bearings, and a baffle 705 is fixed to the hollow tube 704. The hollow tube 704 is slidably connected to the disc 706, and the disc 706 is fixed to the output end of the motor 701. A limit ring 707 is fixed to the disc 706, and the limit ring 707 is slidably connected to the hollow tube 704. The disc 706 is connected to the rotating shaft 605. A centrifugal disc 709 is fixed on the hollow tube 704 and is located inside the drying tube 6. A striking block 710 is fixed on the centrifugal disc 709 at equal angles. A cylinder 711 is fixed on the centrifugal disc 709 and has a chip discharge port 712 at equal angles. A crossbar 713 is fixed on the cylinder 711 and is fixed to the spinning cone block 714. A guide plate 715 is fixed inside the cylinder 711 on the lower side of the spinning cone block 714 and is installed at an angle. The crossbar 713 is fixed to the rotating shaft 605. During the use of the device, such as Figures 1-8 As shown, by starting the motor 701, the drive gear 702 and the disc 706 can be rotated synchronously. With the meshing transmission between the drive gear 702 and the driven gear 703, the hollow tube 704 can be rotated, thereby synchronously driving the baffle 705 to rotate. Through the action of the baffle 705, the air entering the fixed box 3 can be turbulent to ensure the uniformity of air temperature, so as to facilitate the subsequent drying of materials. When the disc 706 rotates, it synchronously drives the through hole 708 to rotate. When the through hole 708 rotates to engage with the hollow tube 704, the heated high-temperature air can enter the drying tube 6 through the hollow tube 704, the centrifugal disc 709, and the cylinder 711, thereby achieving the drying effect of the material. When the through hole 708 rotates to separate from the hollow tube 704, the heated air cannot enter the drying tube 6. Through the engagement and separation of the through hole 708 and the hollow tube 704, the high-temperature air can be intermittently introduced into the drying tube 6 in a pulsed manner. Through the pulsed high-temperature airflow, a strong turbulence effect can be generated, which enhances the heat and mass transfer between gas and solid. Furthermore, through the periodic acceleration and deceleration of the airflow, the material particles vibrate and collide, preventing them from sticking to the wall and agglomerating. At the same time, it can also shorten the residence time of the material in the high-temperature zone and avoid the thermal denaturation of amino acids in the material. When the hollow tube 704 rotates, it can synchronously drive the centrifugal disc 709 and the striking block 710 to rotate. Through the rotation of the centrifugal disc 709 and the striking block 710, the centrifugal force can be used to disperse the material entering the drying tube 6, and the striking action of the striking block 710 can break up and disperse the agglomerated material, thereby ensuring the drying effect of the material. When the material is pulse-dried, when there is no airflow in the cylinder 711 due to the pulse gap, some material will fall into the cylinder 711 under the action of gravity. With the guiding action of the spindle cone block 714 and the guide plate 715 and the centrifugal action of rotation, the material can be discharged into the drying tube 6 through the chip discharge port 712, thereby avoiding the blockage caused by the material entering the hollow tube 704 due to the pulse gap, and ensuring the stable operation of the device. The drying tube 6 has a gradually changing diameter structure, with the upper diameter being 10%-20% larger than the lower diameter. The inner wall of the drying tube 6 is mirror-polished and coated with a polytetrafluoroethylene (PTFE) non-stick coating. An insulation layer covers the outside of the drying tube 6. Temperature sensors 601 are fixed at equal intervals inside the drying tube 6, and one end of the drying tube 6 is fixed to one end of the support rod 602. The other end of the support rod 602 is fixed to the arc panel 603. An inclined material distribution plate 604 is positioned above the arc panel 603 and is fixed inside the drying tube 6. The material distribution plate 604 has material outlets at equal angles. A rotating shaft 605 is connected to the arc panel 603 via a bearing, and an elastic metal strip 606 is fixed to the rotating shaft 605. The elastic metal strip 606 is fixed to a metal ball 607, and the metal ball 607 impacts a protruding strip 608, which is fixed at equal angles inside the drying tube 6. When the material enters the drying tube 6 for pulse drying, such as Figures 1-8As shown, the material moves from bottom to top in the drying tube 6 with the pulsed airflow. The gradually changing diameter structure of the drying tube 6 reduces the material flow rate and ensures the drying time. The non-stick coating of polytetrafluoroethylene reduces the probability of material adhesion. Furthermore, during the upward movement of the material in the drying tube 6, the guiding and diverting effect of the arc panel 603 and the distribution plate 604 further reduces the material's movement speed in the drying tube 6, thereby effectively ensuring the drying quality of the material. When the cylinder 711 rotates, it synchronously drives the crossbar 713 and the rotating shaft 605 to rotate, thereby driving the elastic metal strip 606 and the metal ball 607 to rotate. Through the collision of the metal ball 607 and the protruding strip 608, the drying tube 6 can generate micro-vibration, thereby further preventing the material on the inner wall of the drying tube 6 from sticking. A fixed rod 801 is fixed inside the connecting pipe 8, and a sliding rod 802 is slidably connected to the fixed rod 801. One end of the sliding rod 802 is fixed with a wind-facing plate 803 facing the drying pipe 6. A spring 804 is fixed between the wind-facing plate 803 and the fixed rod 801. The other end of the sliding rod 802 is fixed with a mounting plate 805. The mounting plate 805 is rotatably connected to one end of the connecting rod 806, and the other end of the connecting rod 806 is rotatably connected to a baffle 807. The baffle 807 is slidably connected to the connecting pipe 8 and the cyclone separator 9. A discharge valve 901 is installed below the cyclone separator 9, and an exhaust port 902 is installed on the upper side of the cyclone separator 9. The exhaust port 902 is connected to one end of the connecting pipe 10, and the other end of the connecting pipe 10 is connected to the bag filter 11. After the material has been dried in drying tube 6, such as Figures 1-8 As shown, the dried material enters the connecting pipe 8 and then the cyclone separator 9 through the connecting pipe 8. The material falls automatically under gravity and is subsequently discharged through the discharge valve 901. The gas enters the bag filter 11 through the connecting pipe 10 for dust removal, preventing exhaust gas pollution. During the flow of material and air in the connecting pipe 8, the pre-treatment of the material is pulsed, resulting in poor airflow stability. When the airflow velocity increases, the thrust exerted by the airflow on the windward plate 803 increases, causing the windward plate 803 to move under force, simultaneously driving the sliding rod. The movement of 802 and mounting plate 805, in conjunction with the transmission action of connecting rod 806, causes the two baffles 807 to move in opposite directions under force, reducing the distance between the two baffles 807. When the airflow speed decreases, the thrust of the airflow on the windward plate 803 decreases. Under the action of spring 804, the windward plate 803, sliding rod 802, and mounting plate 805 can move in opposite directions, thereby increasing the distance between the two baffles 807. This ensures stable airflow speed entering the cyclone separator 9 and effectively reduces the impact of front-end pulses or fan fluctuations on the final separation effect of materials.
