Description

Technical Field

[0001] This invention relates to the field of rose product drying technology, specifically to drying equipment for processing rose products. Background Technology

[0002] Roses, as an important aromatic plant, are widely used in food flavoring, tea additives, essential oil extraction, and traditional Chinese medicine formulations. Drying is a crucial step in the initial processing of rose products, aiming to remove moisture, inhibit microbial activity, preserve color and aroma, and facilitate long-term storage and transportation.

[0003] Currently, most drying equipment for processing rose products uses belt drying. During the drying process, the rose products need to be laid flat on the surface of the conveyor belt. If the material accumulates, it is difficult for heat to penetrate, affecting the drying effect. In addition, rose petals have a high sugar content and are prone to sticking together or even charring in high temperature and high humidity environments. The flat conveyor cannot turn the rose products, causing them to stick together during the drying process. At the same time, it causes uneven heating in some areas, affecting the consistency of quality. Based on this, we propose a drying equipment for processing rose products to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a drying device for processing rose products. It employs multi-layer conveying and tumbling of the rose products to disperse them, thus solving the problems of material accumulation during the drying process, which affects the drying effect, and the inability to tumble the rose products, leading to sticking during the drying process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drying equipment for processing rose products, comprising a drying chamber, a mounting frame fixedly installed at the lower end of the drying chamber, a feeding component and a discharging component respectively disposed at the left and right ends of the drying chamber, and a material hopper fixedly installed on the upper left side of the mounting frame, the material hopper being used to hold the rose products to be dried. A conveying component is provided inside the drying chamber for continuously conveying the rose products within the drying chamber and completing the drying process. A turning component is provided inside the drying chamber above the conveying component for periodically agitating the conveyed rose products. Inlet and outlet ports are provided at corresponding positions on the left and right side walls of the drying chamber, and one end of the feeding component extends into the drying chamber through the left-side inlet and outlet port. The drying chamber is connected to the conveying assembly to guide the material to the starting point of the conveying path. One end of the discharge assembly extends to the outside of the drying chamber through the right-side inlet and outlet. The other end of the discharge assembly is adapted to the end of the conveying assembly for discharging the dried material. A blower is fixedly installed at the top of the drying chamber, and an air inlet is opened on the surface of the drying chamber at the corresponding position. The airflow output by the blower enters the interior of the drying chamber through the air inlet. A heating rod is installed at the air inlet. The power of the heating rod is adjustable from 3 to 10 kW. Combined with a temperature control sensor and a PLC control system, a suitable drying temperature range (usually 50 to 80 ℃) can be set according to different rose varieties to prevent overheating and charring. It is used to heat the incoming air to form a hot air drying medium. There are two conveying components arranged in an alternating pattern: an upper conveying component and a lower conveying component. A guide component is provided between the discharge end of the upper conveying component and the inlet end of the lower conveying component. The guide component is used to guide the material to transfer from the upper layer to the lower layer. Each conveying assembly includes a conveyor belt installed inside the drying chamber, with both ends of the conveyor belt fitted and tensioned on moving rollers, and the two moving rollers being rotatably installed between the front and rear inner walls of the drying chamber.

[0006] It should be noted that the upper conveyor belt 4 and the lower conveyor belt 4 can be equipped with independent drive sources (or be driven by the same motor through synchronous belt) so as to adjust the speed difference between the upper and lower layers according to process requirements and achieve differentiated drying rhythm.

[0007] Furthermore, the feeding assembly includes side supports fixedly installed on the outer walls of the front and rear sides of the drying chamber. At least one set of conveying rollers is rotatably installed between the two side supports. A set of identical conveying rollers is also rotatably installed on the left side of the inner side of the drying chamber. The two sets of conveying rollers are connected by a conveyor belt to form a feeding and conveying channel that runs through the inlet and outlet. Multiple vertically arranged dividing plates are fixedly installed at equal intervals along the length of the conveyor belt. The adjacent dividing plates form a spacer chamber for accommodating a single batch of rose products.

[0008] Furthermore, the discharge assembly includes a fixed frame, an inclined discharge guide chute, and a drive adjustment mechanism. The fixed frame is fixedly connected to the outer right wall of the drying chamber. One end of the discharge guide chute is rotatably mounted on the fixed frame via a hinge shaft, and the other end of the discharge guide chute extends obliquely to the outside of the drying chamber through the inlet and outlet ports to receive and discharge the dried rose products output from the lower conveying assembly. The drive adjustment mechanism includes an electric push rod. One end of the electric push rod is hinged to the fixed frame, and the other end of the electric push rod is hinged to the middle of the discharge guide chute. The electric push rod is used to adjust the inclination angle of the discharge guide chute. The inner surface of the discharge guide chute is covered with an anti-stick coating.

[0009] Furthermore, the lower end of the material bin has a funnel-shaped structure and an opening at the bottom. This opening is directly above the conveyor belt of the feeding component, and the rose products stored in the material bin automatically slide onto the conveyor belt by gravity.

[0010] Furthermore, the turning component includes multiple parallel and spaced mounting seats (the spacing should be adapted to the average size of the rose products, preferably 10-20cm). Each mounting seat is horizontally mounted above the conveyor belt. The lower end face of each mounting seat is provided with several actuating columns at equal intervals. The actuating columns can elastically extend and retract up and down. The front end of all mounting seats is rotatably connected to the front side of the inner wall of the drying chamber through a connecting shaft, and the rear end is linked to a transmission box fixed to the rear wall of the drying chamber through a connecting rod. The transmission box is equipped with a reciprocating drive component, which is used to drive all mounting seats to perform reciprocating swing motion synchronously.

[0011] Furthermore, the lower end face of the mounting base is provided with multiple equally spaced connecting slots. The top of the actuating post is embedded in the connecting slot and slides therewith. The top of the actuating post is elastically connected to the top wall of the connecting slot through a compression spring (the preload of the compression spring is 2-5N). The bottom end of the actuating post is fixedly connected to a flexible contact made of rubber.

[0012] Furthermore, the reciprocating drive assembly includes a push cylinder fixedly mounted on the outer wall of the transmission box, a rack disposed at the top inside the transmission box, and multiple transmission gears meshing with the rack. The rack is slidably mounted inside the transmission box in the horizontal direction via a slide rail structure, with one end connected to the piston rod of the push cylinder. Each transmission gear is coaxially fixedly connected to a connecting rod, and each connecting rod is fixedly connected to a corresponding mounting seat. When the push cylinder drives the rack to reciprocate, the meshing transmission drives multiple transmission gears to alternately rotate forward and reverse, thereby causing all mounting seats to reciprocate synchronously.

[0013] Furthermore, the two ends of the moving roller are rotatably connected to the bearing seats on the front and rear inner walls of the drying box, respectively. A second motor is provided at the corresponding position on the outside of the drying box. The second motor is fixedly installed on the mounting frame. The output shaft of the second motor is connected to the front end of the moving roller to drive the conveyor belt to run smoothly.

[0014] It should be noted that motor two is a low-speed motor and is equipped with a gear reduction device to achieve a lower speed to drive the conveyor belt, which increases the residence time of rose products in the drying box. The drying time depends on the product (40-70 minutes).

[0015] Furthermore, the guiding assembly includes a guide plate fixedly installed between the inner walls of the drying chamber, a rotating rod located on the left side of the guide plate, and a fixed rod fixed to the side wall of the chamber. The upper end of the guide plate is hinged to the inner wall of the drying chamber via a rotating shaft, allowing it to swing slightly around a fulcrum. The lower end of the guide plate is connected to the fixed rod via a tension spring, which provides a restoring force. A cam is fixedly installed on the surface of the rotating rod, and the cam profile has an eccentric protrusion structure (the eccentricity should be controlled between 5 and 15 mm). A motor is fixedly installed on the outer wall of the drying chamber, and the output shaft of the motor is connected to the front end of the rotating rod. The motor is used to drive the cam to rotate continuously.

[0016] Furthermore, the guide plate has a flat plate structure that tilts downward to the right. The upper inlet of the guide plate is connected to the discharge end of the upper conveyor belt, and the lower outlet of the guide plate is directly opposite the bearing surface of the lower conveyor belt. When the cam rotates, its protruding part periodically pushes the middle of the guide plate, causing the guide plate to vibrate and swing.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. The drying equipment for processing rose products, by setting up double-layer conveyor components and guide components that are staggered, allows the rose products to turn naturally during the process of being transferred from the upper conveyor belt to the lower conveyor belt. This effectively avoids the problem of uneven drying caused by prolonged heating on one side, and significantly improves the uniformity of drying and the consistency of product quality. 2. The drying equipment for processing rose products utilizes the elastic agitator in the turning component in conjunction with the reciprocating swing mechanism to periodically disturb the material layer during the conveying process. This prevents the rose petals from sticking together and clumping due to their high sugar content and high humidity under high temperature conditions, thereby improving the stability of the drying process and the looseness of the finished product. At the same time, the bottom of the agitator uses a flexible rubber contact and is combined with a spring buffer structure, which makes the movement gentle and the force controllable, minimizing mechanical damage to the delicate rose petals. 3. The drying equipment for processing rose products adopts a feeding assembly with a dividing plate to achieve quantitative and segmented feeding. Combined with the funnel-type gravity discharge structure of the material silo, it ensures that the material enters the drying box continuously and orderly, avoiding accumulation and blockage caused by excessive feeding. 4. The drying equipment for processing rose products uses a guide plate in the conveying component that is driven by a cam to generate a vibrating swing. This not only guides the material to transfer smoothly, but also physically breaks up clumps of material during the falling process, further enhancing the dispersion effect and reducing the need for manual intervention.

[0020] 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.

[0021] Please see Figures 1-8The drying equipment for processing rose products in this embodiment includes a drying chamber 1, a mounting frame 2 fixedly installed at the lower end of the drying chamber 1, a feeding component and a discharging component respectively set at the left and right ends of the drying chamber 1, and a material bin 3 fixedly installed on the upper left side of the mounting frame 2. The material bin 3 is used to hold the rose products to be dried. A conveying component is provided inside the drying chamber 1 to continuously convey the rose products to move within the drying chamber 1 and complete the drying process. A turning component is provided inside the drying chamber 1 above the conveying component to periodically turn the conveyed rose products. Inlet and outlet ports are opened at corresponding positions on the left and right side walls of the drying chamber 1. One end of the feeding component extends into the drying chamber 1 through the left inlet and outlet port and connects with the conveying component to guide the material into the starting point of the conveying path. One end of the discharging component extends to the outside of the drying chamber 1 through the right inlet and outlet port, and the other end of the discharging component is adapted to the end of the conveying component for discharging the dried material. A blower 7 is fixedly installed at the upper end of the drying chamber 1, and an inlet / outlet port is opened on the surface of the drying chamber 1 at the corresponding position. The airflow from the blower 7 enters the drying chamber 1 through the air inlet, and a heating rod 8 is installed at the air inlet to heat the incoming air and form a hot air drying medium. There are two conveying components arranged in an alternating pattern: an upper conveying component and a lower conveying component. A guide component is provided between the discharge end of the upper conveying component and the inlet end of the lower conveying component to guide the material from the upper layer to the lower layer. Each conveying component includes a conveyor belt 4 installed inside the drying chamber 1, with sleeves fitted at both ends of the inner side of the conveyor belt 4. Two moving rollers 401 are rotatably mounted between the front and rear inner walls of the drying chamber 1 and tensioned on the moving rollers 401. The two ends of the moving rollers 401 are rotatably connected to the bearing seats on the front and rear inner walls of the drying chamber 1. A second motor 402 is provided at the corresponding position on the outside of the drying chamber 1. The second motor 402 is fixedly mounted on the mounting frame 2. The output shaft of the second motor 402 is connected to the front end of the moving rollers 401 to drive the conveyor belt 4 to run smoothly. The upper and lower conveyor belts 4 are driven by independent second motors 402 respectively, which makes it easy to adjust the running speed according to the process requirements.

[0022] It should be noted that the conveyor belt 4 is made of high-temperature resistant and non-stick material, such as polytetrafluoroethylene (PTFE) coated mesh belt or stainless steel wire mesh belt, which has good air permeability and anti-aging properties and is suitable for long-term high-temperature operation environment. The surface of the moving roller 401 is covered with a rubber layer or has anti-slip texture to enhance the friction between it and the conveyor belt 4 and prevent slippage and deviation. In addition, edge strips or guide ribs are set on both sides of the conveyor belt 4 to effectively prevent rose products from falling to the edge area of ​​the box due to vibration during the transmission process, ensuring that the material is always in the effective drying area.

[0023] In this embodiment, the feeding assembly includes side brackets 101 fixedly installed on the outer walls of the front and rear sides of the drying chamber 1. At least one set of conveying rollers 102 is rotatably installed between the two side brackets 101. A set of the same conveying rollers 102 is also rotatably installed on the left side of the inner side of the drying chamber 1. The two sets of conveying rollers 102 are connected by a conveyor belt 103 to form a feeding and conveying channel that passes through the inlet and outlet. Multiple vertically arranged dividing plates 104 are fixedly installed at equal intervals along the length direction on the surface of the conveyor belt 103. An interval chamber for accommodating a single batch of rose products is formed between adjacent dividing plates 104. The lower end of the material bin 3 has a funnel-shaped structure and an opening at the bottom. The opening is directly above the conveyor belt 103 of the feeding assembly. The rose products stored in the material bin 3 automatically slide onto the conveyor belt 103 by gravity. The discharge assembly includes a fixed frame 9, an inclined discharge guide 901, and a drive adjustment mechanism. The fixed frame 9 is fixedly connected to the outer right wall of the drying chamber 1. One end of the discharge guide 901 is rotatably mounted on the fixed frame 9 via a hinge shaft, and the other end of the discharge guide 901 extends obliquely to the outside of the drying chamber 1 through the inlet and outlet ports to receive and discharge the dried rose products output from the lower conveying assembly. The drive adjustment mechanism includes an electric push rod 902. One end of the electric push rod 902 is hinged to the fixed frame 9, and the other end of the electric push rod 902 is hinged to the middle of the discharge guide 901. The electric push rod 902 is used to adjust the inclination angle of the discharge guide 901. The inner surface of the discharge guide 901 is covered with an anti-stick coating.

[0024] It should be noted that the height of the dividing plate 104 is 5-15cm and the thickness is 2-5mm. It is made of food-grade stainless steel or engineering plastic with a smooth and burr-free surface to avoid damaging the petals. The spacing between adjacent dividing plates 104 should be slightly larger than the maximum stacking width of a single feeding, usually set at 8-12cm, to ensure that each batch of material is transported independently and does not interfere with each other. The inclination angle of the inner wall of the material bin 3 is not less than 60°, and an adjustable baffle or gate is set at the outlet. Operators can manually or electrically control the discharge flow according to the production rhythm to achieve precise feeding. When the rose products fall into the interval chamber of the conveyor belt 103, they move to the right at a uniform speed with the conveyor belt 103, pass through the inlet and outlet and are smoothly fed into the starting end of the upper conveyor belt 4 to avoid impact causing material splashing or uneven distribution. The discharge guide 901 receives the dried rose products and they naturally slide down to the outside of the drying box 1.

[0025] Please see Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7In this embodiment, the flipping component includes multiple parallel and spaced mounting seats 5, each mounting seat 5 being horizontally mounted above the conveyor belt 4. Each mounting seat 5 has several actuating posts 501 evenly spaced on its lower end face. The actuating posts 501 can elastically extend and retract vertically. The front ends of all mounting seats 5 are rotatably connected to the front side of the inner wall of the drying chamber 1 via connecting shafts, and the rear ends are linked to the transmission box 502 fixed to the rear wall of the drying chamber 1 via connecting rods 503. The transmission box 502 is equipped with a reciprocating drive component, which is used to drive all mounting seats 5 to perform reciprocating swinging motion synchronously. The lower end face of the mounting seat 5 has multiple equally spaced connecting slots 504. The top of the actuating post 501 is embedded in the connecting slot 504 and slides with it. The top of the actuating post 501 is elastically connected to the inner top wall of the connecting slot 504 via a compression spring. The bottom end of the actuating post 501 is fixedly connected to a flexible contact made of rubber.

[0026] In this embodiment, the reciprocating drive assembly includes a push cylinder 5021 fixedly installed on the outer wall of the transmission box 502, a rack 5022 disposed at the top of the transmission box 502, and a plurality of transmission gears 5023 meshing with the rack 5022. The rack 5022 is slidably installed in the transmission box 502 along the horizontal direction through a slide rail structure, and one end of it is connected to the piston rod of the push cylinder 5021. Each transmission gear 5023 is coaxially fixedly connected to a connecting rod 503, and each connecting rod 503 is fixedly connected to the corresponding mounting seat 5. When the push cylinder 5021 drives the rack 5022 to move reciprocally, the meshing transmission drives the plurality of transmission gears 5023 to alternately rotate forward and reverse, thereby causing all mounting seats 5 to swing back and forth synchronously.

[0027] It should be noted that there are 5 to 8 sets of mounting bases 5, evenly distributed along the conveying direction, covering the entire drying area to ensure that the material is continuously disturbed throughout the conveying path. The push cylinder 5021 is a double-acting cylinder with a stroke of 30 to 80 mm. The operating frequency can be set to 5 to 15 reciprocating movements per minute by the PLC controller to adapt to the turning intensity requirements of materials with different moisture contents. The rack 5022 and the transmission gear 5023 are module matched with a transmission ratio of 1:1 to ensure that the swing angle of each mounting base 5 is consistent and to avoid excessive local disturbance. The vertical extension stroke of the actuating column 501 is 10 to 20 mm, and the preload of the compression spring is 3 to 6 N. It can effectively insert into the material layer to disperse the material without damaging the petals due to excessive rigidity. The rubber flexible contact is made of silicone or natural rubber with a hardness of Shore A 40 to 60 degrees, which has good wear resistance and biocompatibility and meets food processing safety standards.

[0028] Please see Figure 1 and Figure 2 , Figure 8In this embodiment, the guiding assembly includes a guide plate 6 fixedly installed between the inner walls of the drying chamber 1, a rotating rod 601 disposed on the left side of the guide plate 6, and a fixed rod 602 fixed to the side wall of the chamber. The upper end of the guide plate 6 is hinged to the inner wall of the drying chamber 1 via a rotating shaft, allowing it to swing slightly around a fulcrum. The lower end of the guide plate 6 is connected to the fixed rod 602 via a tension spring, which provides a restoring force. A cam 603 is fixedly installed on the surface of the rotating rod 601, and the profile of the cam 603 has an eccentric protrusion. The drying chamber 1 has a motor 604 fixedly installed on its outer wall. The output shaft of the motor 604 is connected to the front end of the rotating rod 601. The motor 604 is used to drive the cam 603 to rotate continuously. The guide plate 6 has a flat plate structure that is inclined to the lower right. The upper inlet of the guide plate 6 is connected to the discharge end of the upper conveyor belt 4, and the lower outlet of the guide plate 6 is directly opposite the bearing surface of the lower conveyor belt 4. When the cam 603 rotates, its protruding part periodically pushes the middle of the guide plate 6, causing the guide plate 6 to vibrate and swing.

[0029] It should be noted that the guide plate 6 has an inclination angle of 30° to 45° and a length sufficient to accommodate the entire material drop range. The surface is coated with a Teflon anti-stick coating or anodized to reduce the adhesion of rose products. The tension spring has a stiffness coefficient of 5 to 10 N / cm and retains a certain preload in the initial tension state to ensure that the guide plate 6 can rebound quickly. The eccentricity of the cam 603 is 8 to 12 mm, and the speed of the motor 604 is set to 15 to 25 r / min. The resulting periodic pushing causes the guide plate 6 to vibrate 15 to 25 times per minute, creating a slight shaking effect. While guiding the material down, it also breaks it up, which is especially suitable for rose clumps that are still sticky in the initial drying stage. An appropriate gap is left between the guide plate 6 and the upper and lower conveyor belts 4 to prevent mechanical interference, while allowing a small amount of fine material to fall and be cleaned naturally.

[0030] The working principle of the above embodiments is as follows: In use, the rose products to be dried are pre-loaded into the material hopper 3. Under the action of gravity, the material slides down the funnel-shaped hopper wall and falls sequentially into the interval chambers formed by the dividing plates 104 on the conveyor belt 103 of the feeding component. The motor drives the conveyor belt 103 to run, quantitatively and batch-wise transporting the material into the drying chamber 1 and accurately placing it at the starting end of the upper conveyor belt 4. The upper conveyor belt 4 runs uniformly to the right under the drive of motor 402, carrying the material through the drying zone. During this process, the pushing cylinder 5021 of the turning component periodically pushes... The rack 5022 reciprocates, driving all the transmission gears 5023 to rotate in both directions through meshing transmission. This causes the mounting base 5 to swing back and forth around its front axis. The actuating column 501 at the lower end of the mounting base 5 moves up and down and sweeps laterally across the material layer, achieving gentle agitation, breaking up the accumulation, and promoting moisture evaporation. When the material reaches the end of the upper conveyor belt 4, it naturally falls onto the guide plate 6 of the guiding assembly. At this time, the motor 604 drives the rotating rod 601 and the cam 603 to rotate continuously. The cam 603 pushes the guide plate 6 once for each revolution, causing it to... Vibrational oscillation occurs around the hinge point. This vibration not only accelerates the material's descent but also effectively breaks up agglomerated particles. Subsequently, the material tumbles and slides onto the lower conveyor belt 4 to continue receiving hot air drying. In the hot air system, the blower 7 draws in outside air, heats it through the heating rod 8, and then blows it into the drying chamber 1. The hot air penetrates the material layer from top to bottom, carrying away moisture and dissipating it through the exhaust vents on the top or side of the chamber, forming a continuous drying cycle. After double-layer conveying and multiple agitations, the rose products reach the target moisture content. The drying process varies depending on the moisture content of the roses. Different residence times for rose products require different motor speeds (402). In conventional drying operations, conveyor belt 4 operates at low speed, resulting in a residence time of 40-70 minutes for the rose products. After drying, the rose products are conveyed by the lower conveyor belt 4 to the right-end outlet and fall into the discharge guide trough 901 of the discharge component. The electric push rod 902 can adjust the inclination angle of the guide trough according to the height of the collection container to achieve smooth discharge. The entire process realizes an integrated operation of continuous feeding, automatic turning, dynamic dispersion, and uniform drying, which significantly improves drying efficiency and product quality.
