Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing equipment technology, specifically a device for peeling fresh Gastrodia elata for processing Gastrodia elata. Background Technology

[0002] As an important food and medicine product, the peeling process of Gastrodia elata is a crucial step in ensuring product quality and meeting the needs of subsequent deep processing. Traditional manual peeling methods are inefficient, labor-intensive, and difficult to guarantee uniformity and hygiene standards. Therefore, developing efficient and automated Gastrodia elata peeling equipment is of great significance for improving the processing level of the Gastrodia elata industry. Currently, some Gastrodia elata peeling equipment has been made public, but there is still room for improvement in achieving a comprehensive, efficient, and high-quality processing flow.

[0003] Chinese utility model patent CN221204021U discloses a fresh gastrodia elata peeling device. This device uses a material cylinder, a peeling mechanism, and a shaking mechanism in combination. After peeling, the material cylinder is tilted by a motor in reverse to facilitate discharge. Although this design solves the problem of convenient discharge, it is mainly a batch processing method and it is difficult to realize continuous or assembly line operation. Furthermore, it does not involve the cleaning process before peeling or the immediate treatment process after peeling to prevent oxidation. The shaking mechanism and tilting discharge method may also cause some mechanical damage to the gastrodia elata.

[0004] Chinese utility model patent CN217337324U discloses a device for peeling Gastrodia elata, which peels the Gastrodia elata using a rotating drum with scrapers and spiral ribs. After discharge, a cleaning component is set up to clean the Gastrodia elata. The device has a high degree of automation, but the cleaning process is set after peeling, which may cause secondary contamination of the peeled Gastrodia elata flesh by the peeled epidermis and impurities such as mud and sand. At the same time, the design does not take into account the problem of oxidation and discoloration of Gastrodia elata after peeling, and lacks an immediate anti-oxidation treatment. Its peeling method mainly relies on the scrapers and ribs on the inner wall of the rotating drum, which may limit the uniformity of peeling for irregularly shaped Gastrodia elata.

[0005] Chinese utility model patent CN222264295U discloses a device for peeling fresh Gastrodia elata. This device uses multiple peeling rollers in conjunction with a water spray assembly to peel and rinse within a peeling chamber. This design combines rinsing and peeling, which helps improve peeling quality. However, it may still be an intermittent or semi-continuous operation, and its adaptability to large-scale continuous production needs to be improved. In addition, the solution does not mention pre-cleaning before peeling or anti-oxidation soaking treatment after peeling. Furthermore, if the coordination of multiple peeling rollers and pressure components is not properly controlled, there is a risk of damaging the Gastrodia elata.

[0006] The above design improves the automation level of Gastrodia elata peeling by replacing some manual operations with mechanical structures and considers some peeling or cleaning functions. However, it still has certain limitations. For example, a single peeling function or a simple peeling and cleaning combination fails to effectively pre-clean the fresh Gastrodia elata before peeling, which may lead to impurities such as mud and sand affecting the peeling effect, or even damaging the equipment or contaminating the product. After peeling, the flesh of Gastrodia elata is exposed to the air and is very prone to oxidative browning, affecting its appearance and quality. It is more suitable for batch processing or semi-continuous processing and cannot meet the needs of large-scale, high-efficiency continuous production.

[0007] Therefore, it is necessary to design a fresh gastrodia peeling device for gastrodia processing that integrates pre-cleaning, efficient and gentle peeling, and immediate anti-oxidation treatment, and can achieve automated continuous operation, in order to overcome the shortcomings of existing technologies. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a device for peeling fresh Gastrodia elata for processing, so as to solve the above-mentioned problems.

[0009] The purpose of this utility model is achieved through the following technical solution: A fresh gastrodia elata peeling device for gastrodia elata processing, comprising a washing tank, a peeling tank, and a soaking tank connected in sequence. The washing tank, peeling tank, and soaking tank are respectively provided with a washing section, a peeling section, and a soaking section. Each of the washing section, peeling section, and soaking section includes three rollers arranged in a circumferential array. A auger made of flexible material is fixedly connected to the outer end of each of the three rollers. A bushing is fixedly connected to both ends of each roller along its axial direction. A key shaft is slidably connected to the inner wall of the bushings at the end away from the roller. A universal joint is fixedly connected between two adjacent key shafts along the axis of the key shaft. A universal joint is also fixedly connected to the end of the key shaft in the washing section and the soaking section at the end away from the peeling section. A friction plate is fixedly connected between two adjacent key shafts in the peeling section.

[0010] The universal joint and the outer end of the bushing are both fixedly connected with protective sleeves. Spaces for the passage of Gastrodia elata are provided between the key shafts on the cleaning section, peeling section and soaking section.

[0011] The washing tank and soaking tank, at the ends furthest from the leather box, and the washing section and soaking section, at the ends furthest from the peeling section, are respectively fixedly connected to the feed pipe and the discharge pipe.

[0012] The ends of the feed pipe and discharge pipe that are away from the cleaning tank and soaking tank are both bent upwards, and the ends of the feed pipe and discharge pipe that are away from the cleaning tank and soaking tank are both higher than the top of the cleaning tank and soaking tank.

[0013] The cleaning tank and soaking tank are filled with cleaning solution and soaking solution, respectively. Universal joints on the cleaning section and soaking section, at the ends away from the peeling section, pass through the corresponding cleaning tank and soaking tank, and motors are installed in the passing parts.

[0014] The motor drive shaft is fixedly connected to the corresponding universal joint, and the motor housing is fixedly connected to the corresponding cleaning tank and soaking tank.

[0015] The leather box has a cavity for holding the Gastrodia elata skin, and the protective sleeve is made of the same flexible material as the auger screw.

[0016] Each of the multiple friction plates has a scraper fixedly connected to one end of each other, and the outer ends of the key shafts in the cleaning section, peeling section and soaking section are all fitted with synchronous pulleys.

[0017] Synchronous belts are fitted onto the outer ends of multiple synchronous pulleys on the washing section, peeling section, and soaking section to enable the multiple rollers to rotate synchronously. The ends of the washing section and soaking section closer to the peeling section are higher than the ends farther from the peeling section.

[0018] The beneficial effects of this utility model are:

[0019] This invention organically integrates the three key processes of cleaning, peeling, and soaking Gastrodia elata into one piece of equipment, realizing an automated continuous operation process from raw material input to preliminary finished product output. This greatly reduces manual intervention, significantly shortens processing time, and thus greatly improves overall production efficiency.

[0020] The auger screw conveyor, made of flexible material, can smoothly and gently push the Gastrodia elata through each processing section under the drive of a motor. This design not only ensures that the Gastrodia elata is not easily damaged during the conveying process and maintains the integrity of the raw material, but also assists in friction cleaning in the cleaning section and ensures that the Gastrodia elata passes through in an orderly manner in subsequent sections.

[0021] The friction plate set in the peeling section, especially the scraper added to it, can continuously and effectively scrape the surface of Gastrodia elata. This design makes the peeling process more precise and powerful, and can remove the outer skin of Gastrodia elata more cleanly and thoroughly, thus improving the peeling quality.

[0022] After peeling, Gastrodia elata is immediately placed in a soaking section filled with soaking solution. This immediate soaking process can quickly isolate the air and effectively prevent the peeled Gastrodia elata from oxidizing and turning brown, thus maintaining its natural color and excellent quality. The specially designed feed pipe and discharge pipe are not only easy to operate, but also effectively prevent leakage of the processing liquid.

[0023] Transmission components such as universal joints and bushings are equipped with protective sleeves. These sleeves effectively prevent the intrusion of juices, debris, and dust generated during processing, reducing wear and corrosion of components, thereby extending the service life of these key components and even the entire equipment, reducing maintenance costs, and preventing damage to Gastrodia elata.

[0024] The precise coordination of the synchronous pulley and synchronous belt ensures the synchronous rotation of all rollers and auger screws in the equipment. This synchronous drive mechanism makes the force on the gastrodia elata more uniform and the conveying more stable in each processing stage, avoiding fluctuations in processing quality caused by material accumulation or uneven speed. At the same time, synchronous operation also helps the gastrodia elata to rotate within the cavity.

[0025] Thanks to the synchronized operation of the conveying mechanism and the specific cavity design, the Gastrodia elata can rotate as it moves forward inside the equipment. This rotational characteristic ensures that all surfaces of the Gastrodia elata can be evenly contacted by the cleaning liquid, peeling components, and soaking liquid, ensuring thorough cleaning, more complete peeling, and more thorough soaking, thus significantly improving the overall processing quality.

[0026] The specially designed leather bin has a cavity for holding Gastrodia elata skins, which facilitates the centralized collection and cleaning of waste skins generated during processing. At the same time, the structure of the friction plate and auger screw can prevent the detached skins from getting tangled on the moving parts, ensuring the continuous cleanliness and efficient and stable operation of the equipment.

[0027] The equipment has ample space inside for the passage of Gastrodia elata. Combined with the inclined processing section and the upward pushing action of the auger screw, it ensures that Gastrodia elata of different sizes can flow smoothly inside the equipment, effectively avoiding material jamming and blockage.

[0028] The system is driven by an electric motor and transmits power through a universal joint, making the transmission direct and reliable. The use of the universal joint can also accommodate minor angular deviations that may exist between the drive shafts, reducing the installation accuracy requirements and enhancing the system's adaptability and stability.

[0041] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0042] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0043] Example 1

[0044] like Figures 1 to 10 As shown in the figure, this embodiment discloses a fresh gastrodia peeling device for gastrodia processing, the core structure of which is designed to realize continuous cleaning, peeling and soaking of gastrodia.

[0045] The device includes a washing tank 1, a leather material tank 2, and a soaking tank 3 connected in sequence. These three tanks form the main frame of the device and provide space and support for the subsequent functional sections. The washing tank 1, the leather material tank 2, and the soaking tank 3 are respectively equipped with a washing section 4, a peeling section 5, and a soaking section 6.

[0046] The washing section 4, peeling section 5, and soaking section 6 have similar conveying mechanisms in structure, each including three rollers 7 arranged in a circumferential array. This arrangement helps to form a channel so that the gastrodia elata can pass between the rollers 7. Each roller 7 has a fixed connection at its outer end to a auger screw 8 made of flexible material. When the roller 7 rotates, the spiral structure of the auger screw 8 can push the gastrodia elata forward along the axis of the device, while its flexible material can reduce damage to the gastrodia elata.

[0047] Both ends of the roller 7 are fixedly connected to bushings 9 along its axial direction. These bushings 9 not only fix the roller 7, but also connect to the drive shaft as connecting parts. Multiple bushings 9 are slidably connected to the inner wall of the end away from the roller 7 with key shafts 10. The design of the key shafts 10 allows them to slide within the bushings 9 to accommodate possible small displacements or installation errors.

[0048] To transmit power and allow connection between different axes, the same universal joint 11 is fixedly connected between two adjacent key shafts 10 along the axis of the key shaft 10. This connection method allows power to be smoothly transmitted from one key shaft 10 to the next key shaft 10, even if there is a certain angular deviation between them. In particular, the end of the key shaft 10 on the cleaning section 4 and the soaking section 6 away from the peeling section 5 (i.e. the inlet and outlet drive ends of the device) is also fixedly connected with a universal joint 11 for connecting the drive source.

[0049] In the core peeling section 5, friction plates 13 are fixedly connected between two adjacent key shafts 10 (i.e., in the space between rollers 7). These friction plates 13 are the main components for realizing the peeling function of Gastrodia elata, removing the outer skin through friction with the surface of Gastrodia elata.

[0050] In order to ensure the smooth introduction and export of materials, a feed pipe 14 is fixedly connected to the end of the washing tank 1 away from the leather tank 2 (i.e., the inlet end of the washing section 4). Similarly, a discharge pipe 15 is fixedly connected to the end of the soaking tank 3 away from the leather tank 2 (i.e., the outlet end of the soaking section 6).

[0051] The design of the feed pipe 14 and the discharge pipe 15 takes into account the ease of operation and the prevention of liquid backflow. Specifically, the ends of the feed pipe 14 and the discharge pipe 15 away from the cleaning tank 1 and the soaking tank 3 are both bent upwards. Furthermore, this upward bend makes the ends of the feed pipe 14 and the discharge pipe 15 away from the cleaning tank 1 and the soaking tank 3 higher than the top of the cleaning tank 1 and the soaking tank 3. This design facilitates manual feeding, utilizes gravity to assist feeding, and effectively prevents the liquid in the tank from overflowing from the inlet and outlet.

[0052] To achieve different processing functions, the cleaning tank 1 is pre-filled with cleaning solution to clean the mud and impurities on the surface of the gastrodia elata. The soaking tank 3 is filled with soaking solution to soak the peeled gastrodia elata to prevent oxidation and discoloration and to perform preliminary preservation treatment. As for the drive device, the universal joints 11 (i.e., the drive input points at both ends of the device) located on the cleaning section 4 and the soaking section 6 away from the peeling section 5 respectively pass through the wall panels of the corresponding cleaning tank 1 and soaking tank 3. Motors are installed on the outside of these through-parts as the power source to drive the rotation of the roller 7 in the whole device.

[0053] The installation and power transmission method of the motor are further clarified. The power output shaft of the motor is fixedly connected to the corresponding universal joint 11, thereby directly transmitting the rotational motion of the motor to the universal joint 11, and driving the entire transmission chain. At the same time, the motor housing is fixedly connected to the corresponding cleaning tank 1 and soaking tank 3, ensuring the stability of the motor installation and the reliability of the transmission.

[0054] Work process:

[0055] First, inject an appropriate amount of cleaning solution into the cleaning tank 1 and an appropriate amount of soaking solution into the soaking tank 3, and then connect the power supply to the motors located on the outside of the cleaning tank 1 and the soaking tank 3.

[0056] After the motor starts, its power shaft drives the universal joint 11 connected to it to rotate. Through the universal joint 11, the rotational motion is transmitted to the key shaft 10 of the cleaning section 4 (or soaking section 6). Due to the connection between each key shaft 10 and between the key shaft 10 and the bushing 9, all key shafts 10, bushings 9, rollers 7 and auger screws 8 fixed on rollers 7 in the entire cleaning section 4, peeling section 5 and soaking section 6 start to rotate synchronously or according to the preset transmission relationship.

[0057] Fresh Gastrodia elata to be processed is fed into the feed pipe 14, which is curved upwards and higher than the top of the washing tank 1. Under the action of gravity, the Gastrodia elata slides into the washing section 4 inside the washing tank 1 along the feed pipe 14. After entering the washing section 4, the rotating auger screw 8 moves and rubs the Gastrodia elata, and washes the surface of the Gastrodia elata with the washing liquid to remove dirt and impurities. On the other hand, the spiral structure of the auger screw 8 will push the Gastrodia elata along the channel formed by the roller 7 towards the peeling section 5 inside the peeling box 2.

[0058] After being cleaned, the Gastrodia elata is pushed into the peeling section 5 inside the peeling box 2. In the peeling section 5, the Gastrodia elata moves towards the soaking section 6 inside the soaking box 3 under the continuous pushing of the auger screw 8. During this process, the outer skin of the Gastrodia elata will continuously rub against the friction plate 13 fixed between adjacent key shafts 10. Through this mechanical friction, the friction plate 13 scrapes and peels off the outer skin of the Gastrodia elata. The peeled Gastrodia elata skin will fall to the bottom of the peeling box 2.

[0059] After being peeled, the Gastrodia elata is pushed into the soaking section 6 of the soaking tank 3. In the soaking section 6, the Gastrodia elata is completely submerged in the soaking solution. The rotating auger screw 8 continues to push the Gastrodia elata towards the discharge pipe 15. During the entire movement in the soaking section 6, the Gastrodia elata is fully soaked, which helps to prevent the exposed surface after peeling from oxidizing and discoloring due to contact with air, and may also play a certain role in preservation or pretreatment. Finally, the soaked Gastrodia elata is pushed to the discharge pipe 15 by the auger screw 8 and discharged through the upward-curving discharge pipe 15, which is higher than the top of the soaking tank 3, thus completing the entire processing.

[0060] This embodiment connects the washing tank 1, the peeling tank 2, and the soaking tank 3 in sequence, and sets up a washing section 4, a peeling section 5, and a soaking section 6 inside each tank, respectively. This realizes the automated continuous processing of Gastrodia elata from washing and peeling to soaking, which significantly improves production efficiency and reduces manual intervention.

[0061] The auger screw 8, made of flexible material and mounted on the drum 7, rotates under the drive of a motor. It not only gently transports the gastrodia elata through the washing section 4, peeling section 5, and soaking section 6 in sequence to avoid damage, but also assists in the washing in the washing section 4, ensuring the processing effect and smooth flow of materials.

[0062] The friction plate 13 set in the peeling section 5 can effectively remove the epidermis of the moving Gastrodia elata by friction, realizing the core peeling function. The structure is relatively simple and effective.

[0063] After peeling, the gastrodia elata immediately enters the soaking section 6 of the soaking tank 3 and is covered by the soaking liquid, which effectively prevents the gastrodia elata from oxidizing and discoloring due to contact with air after peeling, thus ensuring the quality and appearance of the gastrodia elata. The upward bending design of the feed pipe 14 and the discharge pipe 15, which are higher than the top of the washing tank 1 and the soaking tank 3, facilitates feeding and discharging, and at the same time effectively prevents the leakage of liquid in the tank.

[0064] The motors installed at both ends of the cleaning tank 1 and the soaking tank 3 drive the roller 7 to rotate via the universal joint 11 and the key shaft 10. The power transmission is direct and reliable. The application of the universal joint 11 allows for a certain angular deviation between the drive shafts, which simplifies the installation requirements and improves the adaptability of the transmission system. The fixed connection between the motor housing and the housings 1 and 3, as well as the fixed connection between the motor power shaft and the universal joint 11, ensures the stable operation of the drive unit.

[0065] Example 2

[0066] like Figures 1 to 10As shown, this embodiment is a further improvement and optimization based on the fresh Gastrodia elata peeling device for processing Gastrodia elata described in Embodiment 1. Therefore, Embodiment 2 includes all the structural features and functions described in Embodiment 1, including a washing tank 1, a peeling tank 2, and a soaking tank 3 connected in sequence; a washing section 4, a peeling section 5, and a soaking section 6 arranged on these tanks; a conveying and processing mechanism in each section consisting of three circumferentially arrayed rollers 7, a flexible auger screw 8 on the rollers 7, a bushing 9, a key shaft 10, and a universal joint 11; a friction plate 13 connecting the key shafts 10 in the peeling section 5; the feed pipe 14 and the discharge pipe 15 of the washing tank 1 and the soaking tank 3, and their upward curvature above the top of the tank; the washing liquid and the soaking liquid filled in the washing tank 1 and the soaking tank 3, respectively; and a structure that provides power to the equipment by driving the universal joint 11 with a motor.

[0067] Based on this, Embodiment 2 is further characterized by the following limitations:

[0068] To enhance the durability and smooth operation of the device and ensure the smooth passage of materials, this embodiment protects key moving parts. Specifically, protective sleeves 12 are fixedly connected to the outer ends of the universal joints 11 in the transmission chain and the outer ends of the bushings 9 at both ends of the rollers 7. In addition, it is specified that sufficient space is provided between each key shaft 10 in the washing section 4, peeling section 5 and soaking section 6 to ensure that the gastrodia elata can pass through smoothly without blockage or jamming.

[0069] The function of the material box 2 and the material of the protective sleeve 12 have been refined. The interior of the material box 2 is specially designed to accommodate the peeled Gastrodia elata skins during processing. This facilitates the collection and cleaning of waste materials and prevents waste skins from affecting machine operation or contaminating the peeled Gastrodia elata. The protective sleeve 12 is made of the same flexible material as the auger screw 8. This flexible material can not only effectively prevent dust, liquids, etc. from entering the interior of the universal joint 11 and bushing 9, extending their service life, but also adapt to the slight deformation and vibration of the moving parts.

[0070] The peeling mechanism and drive synchronization have been significantly enhanced. Multiple friction plates 13 are set in the peeling section 5, and scrapers are fixedly connected to the ends of the plates that are close to each other (i.e., facing the path through which the Gastrodia elata passes). These scrapers act directly on the surface of the Gastrodia elata, and achieve more efficient and thorough peeling through scraping action. At the same time, in order to achieve more precise synchronous drive, synchronous wheels 16 are firmly fitted on the outer ends of all key shafts 10 involved in the transmission in the washing section 4, peeling section 5 and soaking section 6.

[0071] Based on the synchronous pulley 16 set on the key shaft 10, this embodiment introduces a synchronous belt drive mechanism. The outer ends of the multiple synchronous pulleys 16 on the washing section 4, peeling section 5 and soaking section 6 are respectively fitted with synchronous belts 17. Through the connection of the synchronous belts 17, it is ensured that all the rollers 7 in the same section and even the entire device can achieve precise synchronous rotation. In addition, in order to assist the directional conveying of materials under the push of the auger screw 8, the installation angle of the washing section 4 and soaking section 6 has been optimized: the end of these two sections near the peeling section 5 is designed to be higher than the end away from the peeling section 5. This means that the materials in the washing section 4 and soaking section 6 are lifted upward by the auger screw 8 and pushed towards the middle peeling section 5 or the final discharge pipe 15.

[0072] Work process:

[0073] Similar to Example 1, the corresponding liquids are first injected into the cleaning tank 1 and the soaking tank 3, and the motor power is turned on.

[0074] After the motor starts, the power is transmitted to the key shaft 10 through the universal joint 11. Since all key shafts 10 are equipped with synchronous pulleys 16 and connected to each other by synchronous belts 17, all rollers 7 and auger screws 8 in the washing section 4, peeling section 5 and soaking section 6 achieve precise synchronous rotation. During this process, the protective sleeves 12 installed on the universal joint 11 and bushings 9 protect these key connection points from the influence of the external environment and ensure their stable operation.

[0075] Fresh Gastrodia elata to be processed is fed into the feed pipe 14. After entering the washing section 4, the end of the washing section 4 near the peeling section 5 is higher. The screw 8 rotates synchronously, pushing the Gastrodia elata upward and rubbing it clean. The Gastrodia elata passes smoothly through the space reserved between the key shafts 10 and achieves a certain degree of self-rotation during the movement, making the cleaning more thorough.

[0076] The Gastrodia elata is pushed into the peeling section 5. Driven by the synchronously rotating auger screw 8, the Gastrodia elata continues to move towards the soaking section 6. During this process, the scraper fixed on the friction plate 13 powerfully scrapes the surface of the Gastrodia elata, efficiently removing the outer skin. The peeled Gastrodia elata skin falls into the pre-set cavity in the skin box 2 for centralized processing. According to the supplementary working principle, the friction plate 13 also has a certain contact or close-range interaction with the auger screw 8 on the peeling section 5, which can scrape the Gastrodia elata skin that may be attached to the auger screw 8, preventing the Gastrodia elata skin from getting tangled on the auger screw 8, ensuring the cleanliness and operating efficiency of the peeling section. The Gastrodia elata also rotates during the peeling process due to synchronous conveying, ensuring that the whole body is peeled evenly.

[0077] After being peeled, the Gastrodia elata enters the soaking section 6. Since the soaking section 6 is also higher at the end near the peeling section 5, the auger screw 8 continues to push the Gastrodia elata upward and convey it through the soaking liquid. In the soaking liquid, the Gastrodia elata is fully soaked to prevent oxidation and discoloration. The synchronous drive allows the Gastrodia elata to maintain its rotation in the soaking section 6, resulting in a better soaking effect. Finally, the Gastrodia elata is pushed to the discharge pipe 15 for discharge. Throughout the process, the synchronous wheel 16 and the synchronous belt 17 ensure coordinated movement of all components. After being effectively processed in the soaking section 6 of the soaking tank 3, the Gastrodia elata smoothly reaches the discharge pipe 15.

[0078] The added protective sleeve 12 can effectively protect key transmission components such as universal joint 11 and bushing 9, prevent dust and processing liquid corrosion, reduce wear, thereby extending the service life and operational reliability of the device. The protective sleeve 12 uses the same flexible material as the auger screw 8, which can better adapt to movement and provide a seal, while preventing the gastrodia elata from being damaged by rotating parts.

[0079] Space is provided between the key shafts 10 for the passage of Gastrodia elata, ensuring that individual Gastrodia elata of different sizes can move smoothly within the processing section and reducing the risk of blockage.

[0080] The cavity inside the material box 2 for holding the Gastrodia elata peel allows the peeled skin to be collected in a concentrated manner, making it easy to clean and preventing waste skin from scattering and affecting equipment operation or contaminating products. The scraping action of the friction plate 13 on the Gastrodia elata peel that may be wrapped around the auger screw 8 further ensures the continuity and cleanliness of operation.

[0081] The scraper fixedly connected to the friction plate 13 provides a stronger and more precise scraping force than simple friction, which can remove the outer skin of Gastrodia elata more quickly and thoroughly, thus improving the quality and efficiency of peeling.

[0082] By setting a synchronous pulley 16 on the key shaft 10 and connecting it with a synchronous belt 17, the precise synchronous rotation of all rollers 7 and auger screws 8 is achieved. This not only makes the conveying of Gastrodia elata in each processing section more stable and uniform, avoiding accumulation or stretching that may be caused by inconsistent speeds, but also helps Gastrodia elata to rotate during the conveying process, so that cleaning, peeling, soaking and other treatments can be applied to the entire surface of Gastrodia elata, improving the uniformity and thoroughness of processing.

[0083] The design of the washing section 4 and the soaking section 6, with the end closer to the peeling section 5 being higher than the end farther from the peeling section 5, combined with the upward pushing action of the auger screw 8, more effectively transports the gastrodia elata to the next processing stage. This design is especially advantageous when it is necessary to overcome a certain amount of gravity or ensure directional flow.

[0084] The above description is only a preferred embodiment of the present utility model. It should be understood that the present utility model is not limited to the form disclosed herein and should not be regarded as an exclusion of other embodiments. It can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and changes made by those skilled in the art that do not depart from the spirit and scope of the present utility model should be protected within the scope of the appended claims.
