Description

Technical Field

[0001] This invention relates to the field of pharmaceutical drying technology, and in particular to a drying device and process for dextran iron tablets. Background Technology

[0002] Iron is an essential trace element for the human body, participating in various physiological processes. Iron deficiency or poor iron utilization can lead to metabolic disorders and diseases such as anemia.

[0003] Oral iron supplements are the first-line treatment for iron deficiency anemia, including oral formulations such as ferrous sulfate, ferrous lactate, ferrous fumarate, iron dextran, and ferrous succinate. Currently, the main iron supplements available in China include sucrose iron, iron dextran, and sorbitol iron.

[0005] Dextran iron tablets, as an important anti-anemia drug, have a formulation and manufacturing process that have undergone rigorous design and optimization. In terms of the manufacturing process, firstly, using an ethanol solution as a binder, the required amount of raw materials is calculated based on the iron content in the dextran iron raw material, and the amounts of various excipients are then calculated accordingly. Subsequently, the raw materials and excipients are weighed and mixed according to the prescription, forming a uniform soft mass. This mass undergoes granulation, drying, and sizing steps, and is then mixed with magnesium stearate, sodium bicarbonate, and citric acid. After intermediate content testing, the mixture is compressed into tablets. Finally, the uncoated tablets are coated, packaged, and stored after passing finished product inspection.

[0006] The current manufacturing process of dextran iron sheets requires drying, but the existing drying equipment is not automated enough, and manual operation is still required, which is inconvenient. Summary of the Invention

[0007] In order to at least solve one of the above-mentioned technical problems, the present invention aims to provide a drying device and process for dextran iron sheets, thereby improving the degree of automation and the convenience of drying.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A drying device for dextran iron sheets includes a housing with a door hinged to one side. Inside the housing, a feeding tray is installed via a lifting mechanism. The feeding tray has multiple through holes. A mounting frame is fixedly installed inside the housing, and multiple distributing rods are fixedly installed on the upper surface of the mounting frame. When the lifting mechanism lowers the feeding tray, the distributing rods penetrate the through holes and impact and disperse the dextran iron sheets to be dried inside the feeding tray. A hot air mechanism is installed at the bottom of the housing, and a condensation mechanism is connected to one side of the top of the housing.

[0010] Preferably, the lifting mechanism includes vertical electric slides evenly arranged on both sides of the feeding tray. The fixed part of the electric slide is fixedly connected to the inner wall of the box, and the movable part of the electric slide is fixedly connected to the edge of the feeding tray. The mounting frame has an active space for the movable part of the electric slide to move.

[0011] Preferably, a slider is fixedly provided on one side of the feeding tray, and a vertical strip-shaped groove is provided inside the box, with the slider slidingly engaging with the groove.

[0012] Preferably, the cross-section of the slider is T-shaped.

[0013] Preferably, the hot air mechanism includes an air inlet pipe, which is connected to the housing via an air pump, and the air inlet pipe is provided with multiple layers of electric heating mesh.

[0014] Preferably, the condensation mechanism includes a condenser tube communicating with the housing, the condenser tube being L-shaped, a liquid flow tube being provided at the bottom of the condenser tube, and a semiconductor cooling chip being attached to the periphery of the condenser tube.

[0015] Preferably, the top of the material distribution rod is hemispherical.

[0016] A drying process for dextran iron sheets includes the following steps:

[0017] Step 1, Preliminary preparation: Weigh the dextran iron raw material and each excipient according to the required amount, mix the dextran iron raw material with some of the excipients, granulate and shape the granules to obtain the granules to be dried;

[0018] The second step is the drying process: Place the particles to be dried on the feeding tray, activate the lifting mechanism to lower the feeding tray, and allow the distributing rod to penetrate the through hole and impact and disperse the particles. Repeat the impact and dispersion action multiple times. Turn on the hot air mechanism to provide drying hot air. At the same time, the condensation mechanism works to remove moisture.

[0019] The third step, subsequent processes: After drying, the granules are mixed with other excipients, tested as intermediates, compressed into tablets, coated and packaged, and then put into storage after passing inspection.

[0020] The present invention has the following beneficial effects:

[0021] I. Increased Automation: The drying equipment of this invention is equipped with a lifting mechanism. Through components such as an electric slide table, the feeding tray automatically descends, eliminating the need for extensive manual operation to move the tray. During the drying process, the lifting mechanism lowers the feeding tray, causing the distributing rod to impact and disperse the dextran iron sheets to be dried within the tray through the through-hole. The entire dispersion process is completed automatically, reducing manual intervention. Simultaneously, the hot air mechanism and condensation mechanism also automatically activate and operate, providing hot air for the drying process and expelling moisture, significantly improving the automation level of the drying process. This overcomes the shortcomings of existing drying equipment, which often lacks automation and requires significant manual operation, thus enhancing the convenience of the drying process.

[0022] II. Uniform Material Dispersion: Multiple through holes are provided on the feeding tray, and a mounting frame is fixed inside the chamber. The upper surface of the mounting frame has multiple distributing rods. When the lifting mechanism lowers the feeding tray, the distributing rods penetrate the through holes and impact and disperse the dextrorotatory anhydride iron sheets to be dried within the feeding tray. This impact and dispersion action is repeated multiple times. This design ensures uniform dispersion of the dextrorotatory anhydride iron sheets within the feeding tray, preventing material accumulation and allowing each sheet to fully contact the hot air, thereby improving the uniformity and efficiency of drying.

[0023] III. High-efficiency hot air supply: The hot air mechanism includes an air inlet pipe, which is connected to the chamber via an air pump. The air inlet pipe contains multiple layers of electric heating mesh. These multiple layers of electric heating mesh effectively heat the air entering the chamber, providing stable, dry hot air and ensuring the necessary heat for the drying process, further improving the drying effect.

[0024] IV. Timely Removal of Moisture: The condensation mechanism includes a condenser tube connected to the chamber. The condenser tube is L-shaped with a liquid flow pipe at the bottom and semiconductor cooling chips attached to its perimeter. During the drying process, moisture inside the chamber enters the condenser tube. The semiconductor cooling chips lower the temperature of the condenser tube, causing the moisture to condense into liquid and be discharged through the liquid flow pipe. This timely and effective removal of moisture generated during the drying process prevents moisture accumulation inside the chamber from affecting the drying effect and helps improve the overall drying quality.

[0025] V. Stable Movement of the Feeding Pan: A slider is fixedly installed on one side of the feeding pan, and a vertical strip-shaped groove is opened inside the housing. The slider slides and grooves, and the cross-section of the slider is T-shaped. This design makes the feeding pan more stable when it moves under the drive of the lifting mechanism. The cooperation between the T-shaped slider and the groove can prevent the feeding pan from shaking or deviating during movement, ensuring that the distributing rod can accurately pass through the through hole to impact and disperse the dextrorotatory anhydride iron sheet, thus ensuring the stability and reliability of the equipment operation.

[0026] VI. Reasonable design of the material distribution bar: The top of the material distribution bar is designed as a hemispherical shape. When impacting and dispersing the dextran iron sheet, the hemispherical top can reduce the damage to the material and prevent the material from breaking due to sharp impact. At the same time, it can also more smoothly disperse the material through the through hole. While ensuring the drying effect, it also takes into account the integrity of the material, which is conducive to the long-term stable operation of the equipment. Attached Figure Description

[0032] 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.

[0033] First embodiment

[0034] like Figures 1 to 2As shown, a drying device for dextran iron sheets includes a housing 1 with a door hinged to one side. Inside the housing 1, a feeding tray 2 is installed via a lifting mechanism. The feeding tray 2 has multiple through holes 201. A mounting frame 3 is fixedly installed inside the housing 1, and multiple distributing rods 301 are fixedly installed on the upper surface of the mounting frame 3. When the lifting mechanism lowers the feeding tray 2, the distributing rods 301 penetrate the through holes 201 and impact and disperse the dextran iron sheets to be dried inside the feeding tray 2. A hot air mechanism is installed at the bottom of the housing 1, and a condensation mechanism is connected to one side of the top of the housing 1.

[0035] like Figures 1 to 2 As shown, the lifting mechanism includes vertical electric slides 401 evenly arranged on both sides of the feeding tray 2. The fixed part of the electric slide 401 is fixedly connected to the inner wall of the box 1, and the movable part of the electric slide 401 is fixedly connected to the edge of the feeding tray 2. The mounting frame 3 has an active space for the movable part of the electric slide 401 to move.

[0036] like Figures 1 to 2 As shown, the dextran iron sheets to be dried are placed on the feeding tray 2, and the lifting mechanism is activated. The lifting mechanism uses vertical electric slides 401 evenly distributed on both sides of the feeding tray 2. The fixed part of the electric slide 401 is fixed to the inner wall of the housing 1, and the movable part is fixed to the edge of the feeding tray 2. The mounting frame 3 has space for the movable part of the electric slide 401 to move. When the electric slide 401 is activated, its movable part drives the feeding tray 2 downwards. During the descent of the feeding tray 2, multiple distribution rods 301 fixed to the upper surface of the mounting frame 3 inside the housing 1 pass through multiple through holes 201 on the feeding tray 2, thereby impacting and dispersing the dextran iron sheets to be dried in the feeding tray 2. Repeating this impact and dispersion action multiple times ensures that the dextran iron sheets are evenly distributed in the feeding tray 2, preventing material accumulation, increasing the contact area between the material and the hot air, and improving drying efficiency. A hot air mechanism is installed at the bottom of the chamber 1. When the hot air mechanism is working, it delivers dry hot air into the chamber 1 through the air inlet pipe 501 (although the original text does not describe the connection and heating method of the air inlet pipe 501 in detail, it can be inferred that there are corresponding heating and air conveying devices). The hot air flows from bottom to top in the chamber 1, passing through the uniformly dispersed dextran iron sheets, carrying away the moisture in the material, thus drying the dextran iron sheets. A condensation mechanism is connected to one side of the top of the chamber 1. During the drying process, the hot and humid air containing moisture in the chamber 1 rises and enters the condensation mechanism. The condensation mechanism uses refrigeration or other methods (although the original text does not describe the specific refrigeration method of the condensation mechanism in detail, it can be inferred that common refrigeration methods such as semiconductor refrigeration are used) to condense the water vapor in the hot and humid air into liquid water. The liquid water is discharged from the chamber 1 through the liquid flow pipe 602 in the condensation mechanism, while the dried air can continue to circulate or be discharged from the chamber 1, thereby maintaining a dry environment inside the chamber 1 and promoting the continuous and efficient drying process.

[0037] like Figures 1 to 2 As shown, the hot air mechanism includes an air inlet pipe 501, which is connected to the chamber 1 via an air pump 502. Multiple layers of electric heating mesh 503 are installed inside the air inlet pipe 501. After the air pump 502 starts, it draws in outside air through the air inlet pipe 501. As the air flows through the air inlet pipe 501, it passes through the multiple layers of electric heating mesh 503. The electric heating mesh 503 heats up when energized, heating the flowing air and raising its temperature to become dry hot air. Subsequently, the hot air is conveyed into the chamber 1 by the air pump 502, flowing from bottom to top, passing through the dextran iron sheet on the discharge tray 2, and carrying away moisture from the material in the form of water vapor, thereby achieving the purpose of drying the dextran iron sheet. The design of the multiple layers of electric heating mesh 503 increases the contact area and contact time between the air and the heat source, making the air heating more thorough and uniform, ensuring that the temperature of the hot air entering the chamber 1 is stable and meets the drying requirements.

[0038] like Figures 1 to 2 As shown, the condensation mechanism includes a condenser tube 601 connected to the interior of the chamber 1. The condenser tube 601 is L-shaped, with a liquid flow pipe 602 at its bottom. A thermoelectric cooling chip 603 is attached to the periphery of the condenser tube 601. During the drying process, hot, humid air containing moisture rises from the chamber 1 and enters the L-shaped condenser tube 601. The thermoelectric cooling chip 603 attached to the periphery of the condenser tube 601 begins to operate, its cooling surface lowering the temperature of the condenser tube 601. When the hot, humid air comes into contact with the cooler inner wall of the condenser tube 601, the water vapor condenses, changing from a gaseous state to liquid water. Under the influence of gravity, the liquid water flows downwards along the inner wall of the condenser tube 601 and eventually exits the chamber 1 through the liquid flow pipe 602 at the bottom. The air, after condensation and dehumidification, can continue to participate in the drying cycle within the chamber 1 or be discharged from the chamber 1, thereby maintaining a suitable drying environment within the chamber 1 and improving drying efficiency.

[0039] like Figures 1 to 2 As shown, the top of the distributing rod 301 is hemispherical. When the lifting mechanism lowers the feeding tray 2, causing the distributing rod 301 to penetrate the through hole 201 on the feeding tray 2 and impact and disperse the dextran iron sheet, the hemispherical top of the distributing rod 301 reduces damage to the material. Compared to a sharp top design, the hemispherical top provides a smoother contact surface and a more uniform impact force distribution when in contact with the material. This prevents the material from breaking due to excessive local impact, ensuring the integrity of the dextran iron sheet. It also allows for smoother penetration through the through hole 201 to effectively disperse the material, improving the uniformity of drying.

[0040] Second embodiment

[0041] like Figure 3As shown, during the operation of the drying equipment, when the lifting mechanism drives the feeding tray 2 to rise or fall, a slider 402 is fixedly installed on one side of the feeding tray 2, and a matching vertical strip groove 403 is provided inside the housing 1. The slider 402 slides and fits in contact with the groove 403. This structure ensures that the feeding tray 2 can only move in a straight line along the vertical direction defined by the groove 403, avoiding shaking, deviation, or tilting of the feeding tray 2 during lifting and lowering. This ensures the stability and accuracy of the feeding tray 2's movement, thereby ensuring that the distributing rod 301 can smoothly pass through the through hole 201 on the feeding tray 2 to impact and disperse the dextrorotatory anhydride iron sheet, and that hot air can evenly pass through the material for drying, improving the reliability and drying effect of the entire drying process. The cross-section of the slider 402 is T-shaped, which increases the contact area and connection strength between the slider 402 and the groove 403. During the lifting and lowering process of the feeding tray 2, the T-shaped slider 402 can better bear the weight of the feeding tray 2 and the material on it, as well as the various forces generated during the movement, making the connection between the slider 402 and the groove 403 more stable and less prone to failures such as the slider 402 falling off the groove 403, thus further enhancing the stability and durability of the entire structure.

[0042] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
