Rose petal processing drying device

Abstract

This utility model relates to the field of rose petal processing technology and discloses a drying device for rose petal processing, including a drying box and an installation box installed on the top of the drying box. The inner cavity of the installation box is provided with a flow plate, and the bottom of the flow plate is fixedly connected to the drying box. A motor is installed on one side of the top of the flow plate. In this utility model, during operation, the petals to be dried are placed in a filter placement frame. The hot air delivered by the dryer passes through the flow plate and the air inlet slot to the rotating pipe, and then is evenly discharged through the connecting pipe and the ventilation outlet plate. The three-layer structure of the ventilation outlet plate and the filter placement frame cooperates vertically to allow the hot air to penetrate each layer of petals, realizing a three-dimensional hot air circulation from top to bottom. This avoids the problem of overheating of the upper layer and insufficient drying of the lower layer in traditional flat drying, ensuring that each petal can be exposed to uniform heat in the initial drying stage, reducing local moisture residue or high temperature burns caused by stacking, and laying a uniform foundation for subsequent drying.

Description

Technical Field

[0001] This utility model relates to the field of rose petal processing technology, specifically a drying device for processing rose petals. Background Technology

[0002] Rose petals are the petal-like structures of a rose flower, usually fan-shaped or obovate, and come in a variety of colors (such as red, pink, and white). Their surface is covered with hairs and oil glands, secreting aromatic substances such as rose essential oil. They possess both ornamental and practical value, including edible, medicinal, and cosmetic uses, and can be used to make flower tea, essential oils, and skincare products. Because fresh petals have a high water content and are prone to spoilage, and direct storage leads to aroma loss and nutrient depletion, they are difficult to process and distribute. Therefore, drying is necessary to remove most of the moisture, reducing the moisture content to below 10% to extend shelf life. This process also fixes the color and retains active ingredients, facilitating the subsequent production of dried flowers, essential oil raw materials, food additives, and other products, thereby increasing their utilization value and economic benefits.

[0003] Traditional drying equipment generally uses a static flat-laying drying method, which has the following problems: First, the hot air circulation efficiency is low. Hot air usually blows towards the petal pile from only one direction, causing the upper petals to be over-dried or even scorched due to direct contact with high-temperature hot air, while the lower petals suffer from moisture residue and mold due to insufficient ventilation. The uneven heating problem is particularly prominent when processing multi-layered stacked petals, which seriously affects the retention rate of petal color and aroma components and the grade of the finished product. Second, during the static drying process, the petals are prone to stacking and sticking together due to their own weight or wind force. The traditional method of manually turning the material is not only labor-intensive and inefficient, but frequent turning may also cause mechanical damage to the petals and reduce their integrity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drying device for processing rose petals, which has the advantages of uniform drying and preventing sticking and shaking. It solves the problems mentioned in the background technology, such as uneven heating of petals due to low hot air circulation efficiency, easy stacking and sticking of petals during static drying, and low efficiency and easy damage to petals due to manual turning of materials.

[0005] To achieve the aforementioned goals of uniform drying and preventing sticking and shaking, this utility model provides the following technical solution: A drying device for processing rose petals includes a drying box and an installation box mounted on top of the drying box. The inner cavity of the installation box is equipped with a flow-through plate, and the bottom of the flow-through plate is fixedly connected to the drying box. A motor is installed on one side of the top of the flow-through plate. The output end of the motor passes through the flow-through plate and is fixedly connected to a rotating pipe. Air inlet slots are formed on the outer wall of the rotating pipe within the inner cavity of the flow-through plate. The end of the rotating pipe away from the motor passes through the drying box and is fixedly connected to a connecting pipe. Ventilation slots are formed on the upper, middle, and lower outer walls of the connecting pipe. A ventilation outlet plate is fixedly connected to the outer wall of the connecting pipe at the position of the ventilation slot, and the ventilation outlet plate communicates with the ventilation slot. The inner cavity of the drying box is equipped with three filter placement frames, and the connecting pipe passes through the middle of the filter placement frame. The ventilation outlet plate is located at the top of the filter placement frame and matches the filter placement frame. The inner cavity of one drying box has shaking grooves on both sides of the filter placement frame. The inner cavity of the two shaking grooves is slidably connected with connecting plates. The top of the inner cavity of the shaking groove is fixedly connected with a spring, and the other end of the spring is fixedly connected to the connecting plate. One side between the two connecting plates is fixedly connected to the filter placement frame.

[0006] As a further embodiment of this utility model: a ring plate is fixedly connected to the bottom of a filter placement frame, and a uniformly distributed abutment block is fixedly connected through the middle of the side of the ring plate away from the filter placement frame.

[0007] As a further embodiment of this utility model: the outer wall of the connecting pipe is fixedly connected to the bottom of the annular plate one with a connecting rod, and the side of the connecting rod away from the connecting pipe is fixedly connected to the annular plate two. The top of the annular plate two is fixedly connected to the abutting block two, and the abutting block two abuts against the abutting block one.

[0008] As a further improvement of this utility model: a dryer is installed on the top side of the flow plate away from the motor, and the output end of the dryer passes through the flow plate.

[0009] As a further improvement of this utility model, an air inlet filter is installed through one side of the top of the mounting box.

[0010] As a further improvement of this invention, a temperature sensor is installed on one side of the inner cavity of the drying oven.

[0011] As a further improvement of this utility model: a control panel is installed on the front side of the drying oven, and the control panel is electrically connected to the temperature sensor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, during operation, the petals to be dried are placed in the filter placement frame. The hot air delivered by the dryer passes through the flow plate and air inlet slot to the rotating pipe, and then is evenly discharged through the connecting pipe and the air outlet plate. The air outlet plate and the three-layer structure of the filter placement frame cooperate with each other to allow the hot air to penetrate each layer of petals, realizing a three-dimensional hot air circulation from top to bottom. This avoids the problem of overheating of the upper layer and insufficient drying of the lower layer in traditional flat drying, ensuring that each petal can be exposed to uniform heat in the initial drying stage, reducing local moisture residue or high temperature burns caused by stacking, and laying a uniform foundation for subsequent drying.

[0014] 2. In this utility model, after the hot air is conveyed, the motor drives the rotating tube and other components to rotate. The ventilation and air outlet plate releases hot air while rotating. Simultaneously, through the contact linkage between the second contact block and the first contact block, the filter placement frame shakes up and down periodically under the action of the spring, forcing the overlapping petals to disperse and breaking the static stacking state of the petals. This not only avoids adhesion and mold through physical dispersion, but also continuously changes the contact angle between the petals and the hot air during shaking, enhancing air convection and accelerating moisture evaporation. At the same time, the flexible shaking avoids damage to the shape of the petals, ensuring that the dried petals have a bright color and retain their aroma completely, significantly improving the quality of the finished product and production efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 In this embodiment of the present invention, a drying device for processing rose petals includes a drying box 1 and an installation box 2 mounted on top of the drying box 1. The inner cavity of the installation box 2 is provided with a flow plate 3, and the bottom of the flow plate 3 is fixedly connected to the drying box 1. A motor 4 is installed on one side of the top of the flow plate 3. The output end of the motor 4 passes through the flow plate 3 and is fixedly connected to a rotating pipe 5. Air inlet slots 6 are provided on the outer wall of the rotating pipe 5 located within the inner cavity of the flow plate 3. The end of the rotating pipe 5 away from the motor 4 passes through the drying box 1 and is fixedly connected to a connecting pipe 22. Ventilation slots 8 are provided on the upper, middle, and lower outer walls of the connecting pipe 22. A ventilation outlet plate 7 is fixedly connected to the outer wall of the connecting pipe 22 at the position of the ventilation slot 8, and the ventilation outlet plate 7 communicates with the ventilation slot 8. The inner cavity of the drying box 1 is provided with three filter placement frames 9. First, the petals to be dried are placed in the filter placement frames 9, and then the dryer 18 is turned on to deliver hot air. The air enters the rotating pipe 5 through the flow plate 3 and the air inlet slot 6, and is then transmitted to the connecting pipe 22 through the rotating pipe 5. It is then delivered to the ventilation outlet plate 7 through the opening on the outer wall of the connecting pipe 22, and finally discharged through the ventilation outlet plate 7. The ventilation outlet plate 7 and the filter placement frame 9 are both divided into upper, middle and lower layers. The ventilation outlet plate 7 is located above the filter placement frame 9 and cooperates with it, so that the hot air can pass through each layer of petals evenly to achieve preliminary drying. The connecting pipe 22 passes through the middle of the filter placement frame 9. The ventilation outlet plate 7 is located at the top of the filter placement frame 9 and cooperates with the filter placement frame 9. The inner cavity of the drying box 1 is provided with shaking grooves 10 on both sides of the filter placement frame 9. The inner cavity of the two shaking grooves 10 is slidably connected with connecting plates 11. The top of the inner cavity of the shaking grooves 10 is fixedly connected with springs 12, and the other end of the springs 12 is fixedly connected to the connecting plates 11. One side of the two connecting plates 11 is fixedly connected to the filter placement frame 9.

[0023] A ring plate 13 is fixedly connected to the bottom of a filter placement frame 9. A uniformly distributed abutment block 14 is fixedly connected through the middle of the side of the ring plate 13 away from the filter placement frame 9. Connecting rods 15 are fixedly connected to the outer wall of the connecting pipe 22 at the bottom of the ring plate 13. A ring plate 16 is fixedly connected to the side of the connecting rod 15 away from the connecting pipe 22. Abutment blocks 17 are fixedly connected to the top of the ring plate 16, and the abutment blocks 17 abut against the abutment blocks 14. After the hot air is delivered, the motor 4 is started, driving the rotating pipe 5, air inlet slot 6, ventilation outlet plate 7, connecting rods 15, ring plate 16, and abutment blocks 17 to rotate synchronously, thus ventilating. When the air outlet plate 7 rotates, it can output hot air through rotation, further improving the drying uniformity. At the same time, during the rotation of the annular plate 16 and the contact block 17, the contact block 17 will contact the contact block 14 and push it to move upward. The contact block 14 drives the filter placement frame 9 to move upward through the annular plate 13. The dryer 18 is installed on the top side of the flow plate 3 away from the motor 4, and the output end of the dryer 18 passes through the flow plate 3. During this process, the connecting plate 11 slides in the shaking groove 10 and compresses the spring 12. When the contact block 17 disengages from the contact block 14, the filter placement frame 9 quickly resets under the tension of the spring 12, producing a shaking effect. This design effectively prevents petals from overlapping, leading to poor ventilation and uneven heating, reducing the risk of sticking, mold, or scorching. It ensures that each petal is fully exposed to hot air, significantly improving drying consistency and efficiency. An air inlet filter 21 is installed through and installed on one side of the top of the installation box 2. The air inlet filter 21 is installed at the air inlet of the installation box 2 and can filter the intake outside air, effectively blocking dust, impurities, and insects in the air, preventing them from entering the drying box 1 with the hot air and contaminating the petals, ensuring a clean and hygienic drying environment. A temperature sensor 19 is installed on one side of the inner cavity of the drying box 1, and a control panel 20 is installed on the front of the drying box 1. The control panel 20 is electrically connected to the temperature sensor 19. In this drying equipment, the temperature sensor 19 can detect the temperature inside the drying box 1 in real time and feed the data back to the control panel 20. Users can set the temperature threshold or adjust the power of the dryer 18 through the control panel 20 to achieve precise control of the drying temperature, avoiding petal scorching due to excessively high temperature or affecting drying efficiency due to excessively low temperature.

[0024] The working principle of this utility model is as follows: When working, the petals to be dried are first placed in the filter placement frame 9, and then the dryer 18 is turned on to deliver hot air. The hot air enters the rotating pipe 5 through the flow plate 3 and the air inlet slot 6, and is then transmitted to the connecting pipe 22 through the rotating pipe 5. It is then delivered to the ventilation outlet plate 7 through the opening on the outer wall of the connecting pipe 22, and finally discharged through the ventilation outlet plate 7. The ventilation outlet plate 7 and the filter placement frame 9 are both divided into upper, middle and lower layers. The ventilation outlet plate 7 is located above the filter placement frame 9 and cooperates with it so that the hot air can pass through each layer of petals evenly to achieve preliminary drying.

[0025] After the hot air delivery is completed, the motor 4 is started, driving the rotating pipe 5, air inlet slot 6, ventilation and exhaust plate 7, connecting rod 15, annular plate 16, and contact block 17 to rotate synchronously. When the ventilation and exhaust plate 7 rotates, it can output hot air through rotation, further improving the drying uniformity. At the same time, during the rotation of annular plate 16 and contact block 17, contact block 17 will contact contact block 14 and push it upward. Contact block 14 drives the filter placement frame 9 to move upward through annular plate 13. During this process, the connecting plate 11 slides in the shaking groove 10 and compresses the spring 12. When contact block 17 disengages from contact block 14, the filter placement frame 9 quickly resets under the tension of the spring 12, producing a shaking effect. This design can effectively prevent petals from overlapping, causing poor ventilation and uneven heating, reducing the risk of sticking, mold, or scorching, ensuring that each petal can fully contact the hot air, and significantly improving drying consistency and efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
