Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical powder drying technology, and in particular to a pharmaceutical powder dehumidification and drying device. Background Technology

[0002] Medicinal powder is a powdery substance formed by processing and pulverizing drugs. The production of medicinal powder is usually for the purpose of facilitating the administration, storage, and efficacy of drugs. Dehumidification and drying equipment is a device specifically used to remove excess moisture from medicinal powder and control its moisture content. It is widely used in the drying process of powdered materials in the pharmaceutical, chemical, and food industries. Its core purpose is to reduce the humidity of medicinal powder through physical or chemical methods to prevent clumping, mold growth, or degradation of active ingredients, thereby ensuring the stability and effectiveness of the product.

[0003] Most existing dehumidification and drying devices involve heating the powder while it is still, which may result in uneven drying. This can lead to inconsistencies in the color and texture of the powder. For example, some powder may become too dry, turning darker or even charred, while some powder may be lighter in color. Overall, the powder appears uneven in color, affecting the product's appearance. This also causes variations in the moisture content of the powder. Areas with higher moisture content are more prone to absorbing moisture, creating conditions for microbial growth and accelerating drug deterioration. Overly dry areas may experience structural damage, reducing stability and making the active ingredients more likely to decompose or volatilize, thus shortening the drug's shelf life and effectiveness.

[0004] Therefore, since most of the existing dehumidification and drying devices involve heating the powder while it is still, which may result in uneven drying, inconsistent color and texture of the powder, affecting the appearance quality of the product, and varying moisture content, thus reducing the shelf life and effectiveness of the drug, a dehumidification and drying device for the powder can be designed with a stirring component to ensure that the powder is completely dried. Utility Model Content

[0005] To overcome the problem that most existing dehumidification and drying devices heat the powder while it is still, which may result in uneven drying of the powder, causing inconsistencies in color and texture, affecting the appearance quality of the product, and also causing different moisture content in the powder, reducing the shelf life and effectiveness of the drug.

[0006] The technical solution of this utility model is as follows: a dehumidifying and drying device for medicinal powder, including an outer shell, a round cover and an air outlet pipe; a round cover for sealing the outer shell is provided on the top of the outer shell, an air outlet pipe for venting excess gas inside the outer shell is installed on the upper end of the round cover, a rotating column is installed in the middle of the round cover, a rotating motor is installed on the upper end of the rotating column, support rods are symmetrically installed on the outer side of the upper end of the rotating column, an arc-shaped scraper is installed on the end of the support rod away from the rotating column, and multiple sets of stirring plates are linearly arranged around the outside of the rotating column.

[0007] Furthermore, an annular heat-conducting plate is installed on the inner side of the outer casing, forming an annular groove between the annular heat-conducting plate and the outer casing, and a heating coil is provided between the annular heat-conducting plate and the outer casing.

[0008] Furthermore, an operation panel is installed on one side of the outer casing. A power module that passes through the outer casing and is connected to the heating coil is located on one side of the operation panel. A temperature and humidity sensor that passes through the outer casing and the annular heat-conducting plate and extends into the annular heat-conducting plate is located on the side of the operation panel away from the power module.

[0009] Furthermore, a discharge pipe is installed at the lower end of the outer casing, and a first telescopic valve is provided at the connection between the discharge pipe and the outer casing. A first electromagnetic control valve is installed on the outer side of the first telescopic valve.

[0010] Furthermore, two sets of handles are horizontally installed on the upper end of the round cover, and an annular sealing ring is installed at the lower edge of the round cover. The annular sealing ring drives the round cover to fit and connect with the outer shell and the annular heat-conducting plate along the annular groove.

[0011] Furthermore, a second telescopic valve is provided at the connection between the air outlet pipe and the round cover. A second electromagnetic control valve is installed on the outer side of the second telescopic valve. Multiple sets of arc-shaped snap-fit ​​grooves are opened around the upper part of the inner wall of the air outlet pipe. A pressure sensor is provided on one side of the air outlet pipe, which passes through the round cover and extends into the inner body of the outer shell. The pressure sensor is electrically connected to the second electromagnetic control valve.

[0012] Furthermore, a large perforated filter plate is provided inside the air outlet pipe, and multiple sets of arc-shaped snap-fit ​​blocks are installed around the outside of the large perforated filter plate. The arc-shaped snap-fit ​​blocks are positioned and snap-fitted with the air outlet pipe along the arc-shaped snap-fit ​​groove. A small perforated filter plate is provided above the large perforated filter plate and is fixedly connected to the arc-shaped snap-fit ​​blocks.

[0013] The beneficial effects of this invention are as follows: The powder is carefully poured into a specially designed outer casing, and then the ingeniously designed round cap is gently closed. This instantly activates the heating coil built into the casing, which then efficiently and gently dehumidifies and dries the powder. During this process, a specially designed stirring plate located beneath the round cap plays a crucial role. It rotates continuously, meticulously dispersing and agitating the powder to ensure it doesn't accumulate in any corner but is evenly distributed throughout the casing. This design allows the powder to be heated and dehydrated evenly during drying, effectively preventing the decomposition, deterioration, or loss of active ingredients due to localized overheating or excessive moisture. Powder treated in this way retains its active ingredients intact, resulting in a more stable and reliable therapeutic effect. Furthermore, the dried powder has a more uniform and bright color and consistent particle size, significantly improving its overall appearance. This not only enhances the overall quality and image of the medicine but also greatly increases patient trust and satisfaction. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] like Figures 1-4 As shown, the powder dehumidification and drying device includes an outer shell 1, a round cover 2, and an exhaust pipe 3. The round cover 2 is provided above the outer shell 1 for sealing the outer shell 1. An exhaust pipe 3 for venting excess gas inside the outer shell 1 is installed at the upper end of the round cover 2. A rotating column 203 is installed in the middle of the round cover 2. A rotating motor 204 is installed at the upper end of the rotating column 203. Support rods 205 are symmetrically installed on the outer side of the upper end of the rotating column 203. An arc-shaped scraper 206 is installed at the end of the support rod 205 away from the rotating column 203. Multiple sets of stirring plates 207 are linearly arranged around the outside of the rotating column 203.

[0023] An annular heat-conducting plate 101 is installed on the inner side of the outer casing 1. An annular groove is formed between the annular heat-conducting plate 101 and the outer casing 1. A heating coil 102 is provided between the annular heat-conducting plate 101 and the outer casing 1.

[0024] An operation panel 103 is installed on one side of the outer casing 1. A power module 104 is provided on one side of the operation panel 103, which passes through the outer casing 1 and is connected to the heating coil 102. A temperature and humidity sensor 105 (the model of the temperature and humidity sensor 105 is RS485) is provided on the side of the operation panel 103 away from the power module 104, which passes through the outer casing 1 and the annular heat-conducting plate 101 and extends into the annular heat-conducting plate 101. The temperature and humidity sensor 105 monitors the temperature and humidity in the outer casing 1 in real time and makes timely adjustments.

[0025] A discharge pipe 106 is installed at the lower end of the outer casing 1. A first telescopic valve 107 is provided at the connection between the discharge pipe 106 and the outer casing 1. A first electromagnetic control valve 108 (model AD-8A-N-G1) is installed on the outer side of the first telescopic valve 107. The first telescopic valve 107 is opened under the control of the first electromagnetic control valve 108, so that the dried powder can be discharged through the discharge pipe 106.

[0026] Two sets of handles 201 are horizontally installed on the upper end of the round cover 2, and an annular sealing ring 202 is installed on the lower edge of the round cover 2. The annular sealing ring 202 drives the round cover 2 to fit and connect with the outer shell 1 and the annular heat-conducting plate 101 along the annular groove. When the handles 201 are lifted, the annular sealing ring 202 drives the round cover 2 to fit and connect with the outer shell 1 and the annular heat-conducting plate 101 along the annular groove, so that the outer shell 1 forms a sealed state.

[0027] First, pour the powder into the annular heat-conducting plate 101. Then, lift the handle 201. The annular sealing ring 202 causes the round cover 2 to fit and connect with the outer shell 1 and the annular heat-conducting plate 101 along the annular groove, thus sealing the outer shell 1. Next, operate the control panel 103 to start the power module 104, which powers the heating coil 102 and begins to dissipate heat. The annular heat-conducting plate 101 dehumidifies and dries the powder. During the heating process, driven by the rotating motor 204, the rotating column 203 drives the support rod 205 and the stirring plate 207 to rotate, thereby finely agitating the powder. The powder is dispersed and shaken to ensure that it does not accumulate in a corner, but is evenly dispersed inside the outer shell 1. At the same time, the support rod 205 drives the arc-shaped scraper 206 to rotate along the inner wall of the annular heat-conducting plate 101, which can scrape off the powder adhering to the inner wall of the annular heat-conducting plate 101 to prevent the powder from drying too much. Then, the temperature and humidity in the outer shell 1 are monitored in real time by the temperature and humidity sensor 105 and adjusted in time. Finally, the first telescopic valve 107 is opened by the control of the first electromagnetic control valve 108, so that the dried powder can be discharged through the discharge pipe 106.

[0028] Example 2

[0029] Based on Example 1, such as Figure 1 , Figures 4-5 As shown, a second telescopic valve 301 is provided at the connection between the air outlet pipe 3 and the round cover 2. A second electromagnetic control valve 302 is installed on the outer side of the second telescopic valve 301. Multiple sets of arc-shaped snap-fit ​​grooves 303 are formed around the upper part of the inner wall of the air outlet pipe 3. A pressure sensor 307 (model MS5611) is provided on one side of the air outlet pipe 3, which passes through the round cover 2 and extends into the outer shell 1. The pressure sensor 307 is electrically connected to the second electromagnetic control valve 302.

[0030] The inner side of the exhaust pipe 3 is provided with a large perforated filter plate 304. Multiple sets of arc-shaped snap-fit ​​blocks 305 are installed around the outside of the large perforated filter plate 304. The arc-shaped snap-fit ​​blocks 305 are positioned and snapped into the exhaust pipe 3 along the arc-shaped snap-fit ​​groove 303. A small perforated filter plate 306 is provided above the large perforated filter plate 304 and is fixedly connected to the arc-shaped snap-fit ​​blocks 305. The large perforated filter plate 304 initially intercepts larger powder particles, and then the small perforated filter plate 306 further intercepts smaller powder particles, preventing the powder from entering the atmosphere with the gas.

[0031] When the air pressure in the outer casing 1 is too high due to the action of the air pressure sensor 307, the second telescopic valve 301 is opened under the control of the second electromagnetic control valve 302, and the excess gas is discharged through the air outlet pipe 3. During this process, since the gas may carry powder, larger powder particles can be initially intercepted by the large pore filter plate 304, and then smaller powder particles can be further intercepted by the small pore filter plate 306, preventing the powder from entering the atmosphere with the gas. After this batch of powder has dried, the large pore filter plate 304 and the small pore filter plate 306 are removed, and the powder intercepted on them is recycled to avoid waste. At the same time, they are cleaned to avoid affecting the subsequent ventilation performance. After cleaning, the arc-shaped locking block 305 drives the large pore filter plate 304 and the small pore filter plate 306 to be positioned and locked with the air outlet pipe 3 along the arc-shaped locking groove 303, and can then continue to be used.
