Description

Technical Field

[0001] This application relates to the field of extract processing technology, and in particular to dryers for the production of plant extracts. Background Technology

[0002] Natural plant extracts are products made from plants as raw materials, obtained and concentrated through physicochemical extraction and separation processes to target and concentrate one or more active ingredients without altering their structure. In the processing of natural plant extracts, the extract typically needs to be dried into powder or granules. During drying, the collected plant extract paste is spread evenly on a drying tray, which is then placed in a drying oven that provides a specific temperature to reduce the moisture content of the extract paste.

[0003] Existing plant extract dryers, when in operation, only allow air to enter from the top or bottom in a single direction, resulting in uneven distribution of hot airflow. This leads to varying degrees of heating and contact with the hot airflow on different trays within the drying chamber, resulting in inconsistent moisture evaporation rates and localized over-drying or under-drying. Furthermore, a hard crust easily forms on the material surface, hindering the escape of internal moisture, prolonging drying time, reducing production efficiency, and making it difficult to ensure consistent product quality between batches. Additionally, material residue remains on the inner walls and filter pores of the fixed trays after drying, making thorough cleaning difficult and prone to cross-contamination, thus reducing extract quality. Therefore, a new plant extract dryer is proposed to address these issues. Utility Model Content

[0004] This embodiment provides a plant extract production dryer that suffers from uneven hot air distribution due to air intake from only the top or bottom, resulting in uneven drying of materials, surface crusting, low efficiency, and unstable quality. In addition, the fixed installation of the material tray makes it easy for residues to remain and difficult to clean, which can easily lead to cross-contamination.

[0005] According to one aspect of this application, a plant extract production dryer is provided, comprising a housing, a rotating shaft rotatably connected to the interior of the housing via bearings, a motor fixedly mounted on the housing, an output shaft of the motor extending into the housing and fixedly connected to one end of the rotating shaft, a fixed cylinder fixedly mounted on the rotating shaft, an upper plate and a lower plate fixedly mounted at the top and bottom of the fixed cylinder respectively, a plurality of equally spaced material trays provided on the fixed cylinder, an mounting block fixedly mounted at one end of each plurality of material trays, and a filter screen provided on each plurality of material trays; The inner wall of the box is fixedly installed with multiple equally spaced fixing plates, one end of each fixing plate extending above the material tray, and multiple equally spaced material feeding rods are provided on each fixing plate.

[0006] In this technical solution, the cross-section of each of the multiple material trays is semi-circular, and the multiple material trays are evenly distributed on both sides of the fixed cylinder.

[0007] In this technical solution, the fixed cylinder is provided with multiple equally spaced mounting slots, and mounting blocks can be inserted into the interior of each of the multiple mounting slots.

[0008] In this technical solution, each of the multiple mounting blocks has two through holes, and each of the multiple mounting blocks has two bolts inside. Both bolts pass through the two mounting blocks through the through holes and are threaded with lock nuts.

[0009] In this technical solution, a plurality of auxiliary wheels are fixedly installed at the bottom end of the lower plate, and the bottom ends of the plurality of auxiliary wheels abut against the housing.

[0010] In this technical solution, the box body has two ventilation openings, and ventilation nets are installed at the positions of the two ventilation openings.

[0011] In this technical solution, air distribution plates are fixedly installed on both sides of the inner cavity of the box, and multiple equally spaced jet heads are connected to both air distribution plates.

[0012] In this technical solution, both of the gas distribution plates are connected to heating tubes, and one end of each heating tube extends to the outside of the box and is connected to an external heating system.

[0013] In this technical solution, the box body has two doors that are rotatably connected by hinges, and each of the two doors is fixedly equipped with a handle.

[0014] In this technical solution, four support legs are fixedly installed at the bottom of the box.

[0015] Through the above embodiments of this application, by activating the external heating system, hot airflow is evenly sprayed onto the materials on each tray through multiple jet nozzles on the air distribution plate, and the motor is started simultaneously, thereby driving the material trays on both sides to rotate synchronously; when the material tray rotates to the bottom of the fixed plate, the material lever on the fixed plate will turn the material in the tray, which can break the crust formed on the surface of the material due to moisture evaporation, and can also make the upper and lower layers of the material fully contact the hot airflow, greatly shortening the drying time and improving the overall drying uniformity; When disassembling the material tray, simply loosen the locking nut and remove the bolts to pull the tray directly out of the mounting slot of the fixed cylinder. This allows the material tray and the filter screen on its surface to be completely separated from the housing, facilitating thorough cleaning of the inner wall of the material tray and the pores of the filter screen. This avoids cleaning dead spots caused by the fixed position of the material tray and also makes it easy to quickly replace aging or damaged material trays or filter screens, reducing the operational intensity and time cost for maintenance personnel and reducing the risk of material residue and cross-contamination.

[0027] Please see Figure 1-5As shown, a plant extract production dryer includes a housing 1. Inside the housing 1, a rotating shaft 15 is rotatably connected via bearings. A motor 6 is fixedly mounted on the housing 1. The output shaft of the motor 6 extends into the housing 1 and is fixedly connected to one end of the rotating shaft 15. A fixed cylinder 7 is fixedly mounted on the rotating shaft 15. An upper plate 4 and a lower plate 14 are fixedly mounted at the top and bottom of the fixed cylinder 7, respectively. Multiple material trays 8 are arranged at equal intervals on the fixed cylinder 7. An installation block 5 is fixedly mounted on one end of each of the multiple material trays 8. A filter screen 11 is provided on each of the multiple material trays 8. The inner wall of the box 1 is fixedly installed with a plurality of equally spaced fixing plates 17, one end of each fixing plate 17 extends above the material tray 8, and a plurality of equally spaced material feeding rods 18 are provided on each fixing plate 17.

[0028] In this technical solution, the cross-sections of the multiple material trays 8 are all semi-circular, and the multiple material trays 8 are evenly distributed on both sides of the fixed cylinder 7. In this technical solution, the fixed cylinder 7 is provided with a plurality of equally spaced mounting slots 16, and mounting blocks 5 can be inserted into the interior of each of the plurality of mounting slots 16.

[0029] In this technical solution, each of the multiple mounting blocks 5 has two through holes, and each of the multiple mounting blocks 5 has two bolts 21 inside. The two bolts 21 pass through the two mounting blocks 5 through the through holes and are threadedly connected to a locking nut 22.

[0030] In this technical solution, a plurality of auxiliary wheels 12 are fixedly installed at the bottom end of the lower plate 14, and the bottom ends of the plurality of auxiliary wheels 12 abut against the housing 1.

[0031] In this technical solution, the housing 1 has two ventilation openings, and ventilation nets 9 are provided at the positions of the two ventilation openings on the housing 1.

[0032] In this technical solution, air distribution plates 3 are fixedly installed on both sides of the inner cavity of the box 1, and multiple jet heads 10 are connected to both air distribution plates 3 at equal distances.

[0033] In this technical solution, heating tubes 2 are connected to both of the gas distribution plates 3, and one end of each of the two heating tubes 2 extends to the outer end of the box 1 and is connected to the external heating system.

[0034] In this technical solution, the box body 1 is rotatably connected to two boxes 20 by hinges, and each of the two boxes 20 is fixedly installed with a handle 19.

[0035] In this technical solution, four support legs 13 are fixedly installed at the bottom of the box body 1.

[0036] When in use, the plant extract to be dried is evenly spread on multiple trays 8 by opening the door 20 and handle 19, which improves the subsequent drying efficiency, expands the contact range between the material and the hot air, and avoids uneven drying caused by local accumulation. The trays 8 are connected to the mounting slots 16 of the fixed cylinder 7 by mounting blocks 5, and then bolts 21 are used to pass through the through holes of the mounting blocks 5 and are fixed with locking nuts 22. When disassembling, only the locking nuts 22 need to be loosened and the bolts 21 need to be removed to directly pull the trays 8 out of the mounting slots 16 of the fixed cylinder 7 without disassembling the fixed cylinder 7, the rotating shaft 15 and other core components. This allows the trays 8 and the filter screen 11 on the surface to be completely separated from the box body 1, which is convenient for thorough cleaning of the inner wall of the trays 8 and the pores of the filter screen 11. This avoids cleaning dead corners caused by the fixed position of the trays 8 and also facilitates quick replacement of aged or damaged trays 8 or filter screens 11, reducing the operation intensity and time cost of maintenance personnel and reducing the risk of material residue and cross-contamination. After loading is completed, the door 20 is closed to ensure the airtightness of the box body 1. The external heating system is activated, and hot air is delivered through heating pipe 2 to the air distribution plate 3 inside the chamber 1. Multiple jet nozzles 10 on the air distribution plate 3 then evenly spray the hot air onto the materials in each tray 8, ensuring uniform distribution and preventing localized overheating that could damage the extract's effective components. This also ensures a consistent drying rate for the materials in each tray 8. Simultaneously, motor 6 is started, and its output shaft drives rotating shaft 15. The fixed cylinder 7 rotates with shaft 15, causing the trays 8 on both sides to rotate synchronously. When the trays 8 rotate to below the fixed plate 17, the material-pulling rod 18 on the fixed plate 17 agitates the materials in the trays 8, breaking up any crusts formed on the material surface due to moisture evaporation. It can also ensure that the upper and lower layers of the material are in full contact with the hot airflow, which can significantly shorten the drying time and improve the overall drying uniformity. The filter screen 11 on the material tray 8 can allow the hot airflow to penetrate the material layer and further accelerate the evaporation of moisture. The humid air generated by evaporation is discharged through the ventilation port of the box 1. The ventilation screen 9 can prevent external impurities from entering the box 1 and ensure a clean drying environment. It maintains the dry atmosphere inside the box 1 and avoids the retention of humid air, which affects the drying efficiency. At the same time, it ensures the purity of the product. The auxiliary wheel 12 at the bottom of the lower plate 14 rotates with the fixed cylinder 7 and abuts against the box 1, which can enhance the stability of the fixed cylinder 7 when it rotates, prevent the material tray 8 from shaking and causing the material to spill, and improve the stability of the equipment operation.

[0037] The advantages of this application are: 1. By activating the external heating system, hot air is evenly sprayed onto the material on each tray 8 through multiple jet nozzles 10 on the air distribution plate 3, and the motor 6 is activated simultaneously, thereby driving the trays 8 on both sides to rotate synchronously; when the tray 8 rotates to the bottom of the fixed plate 17, the material-pushing rod 18 on the fixed plate 17 will turn the material in the tray 8, which can break the crust formed on the surface of the material due to moisture evaporation, and can also make the upper and lower layers of the material fully contact the hot air, greatly shortening the drying time and improving the overall drying uniformity; 2. When disassembling the material tray 8, simply loosen the locking nut 22 and remove the bolt 21 to directly pull the material tray 8 out of the mounting groove 16 of the fixed cylinder 7. This allows the material tray 8 and the filter screen 11 on its surface to be completely separated from the housing 1, facilitating thorough cleaning of the inner wall of the material tray 8 and the pores of the filter screen 11. This avoids cleaning dead corners caused by the fixed position of the material tray 8 and also facilitates quick replacement of aged or damaged material trays 8 or filter screens 11, reducing the operational intensity and time cost for maintenance personnel and reducing the risk of material residue and cross-contamination.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
