Description

Technical Field

[0001] This invention relates to the field of dried fruit production and cleaning technology, specifically to a cleaning device for dried fruit production and processing. Background Technology

[0002] Dried fruit is a food made from green food fruits through dehydration and drying without sugaring. When making dried fruit from fresh fruit, the fresh fruit needs to be washed first, so fruit washing equipment is required.

[0003] Currently, traditional cleaning equipment used in dried fruit production and processing often employs water tumbling or brush friction for cleaning. However, dried fruit is soft and has a fragile skin. Collisions and friction with hard components within the equipment make it prone to cracking, deformation, and surface pulp loss under this strong mechanical force, leading to increased product scrap rates and damaged appearance. Furthermore, the numerous wrinkles and irregular shapes of dried fruit make it difficult for traditional soaking or spraying methods to effectively reach the crevices and wrinkles, resulting in residue. While some existing methods use flexible clamping to hold dried fruit during cleaning, achieving better results, a balance between cleanliness and integrity is required. Traditional brushing or soaking cannot ensure stable rotation in a semi-floating state. Therefore, a new type of cleaning equipment for dried fruit production and processing is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning device for dried fruit production and processing, in order to solve the problems mentioned in the background art, which are prone to cracking, deformation and shedding of the surface pulp under strong mechanical action, resulting in increased product scrap rate and damaged appearance.

Detailed Implementation

[0034] 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.

[0035] To address the problem of fruit damage caused by strong mechanical cleaning in existing systems, this invention provides a cleaning device for dried fruit production and processing, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, the system includes: a cleaning chamber 200 with multiple chambers (at least one layer) inside; mesh frame assemblies 700 forming multiple sets that are slidably connected to the inner walls of different chamber layers; the mesh frame assembly 700 includes at least one regular hexagonal mesh opening 701; the inner wall edge of the mesh opening 701 is provided with at least three elastic protrusions 703 for adaptively supporting and positioning individual dried fruits, so that they are partially immersed in water and partially exposed above the water surface; an elastic spring 702 is installed in the groove of the inner wall edge of the mesh opening 701; and a smooth arc-shaped curved surface 704 is installed at the front end of the elastic protrusion 703. A cleaning liquid injection pipe structure 400 is connected to the top of the side end of the cleaning chamber 200; the ports of the cleaning liquid injection pipe structure 400 are connected to an external filter purification pump box and a cleaning pump box, respectively; a side branch valve pipe of the cleaning liquid injection pipe structure 400 is connected to a sorting cleaning conveyor belt 100; and a filter screen with different holes is added inside the sorting cleaning conveyor belt 100 for preliminary separation of dried fruits and impurities. A transition buffer hopper 300 is installed at the bottom of the side of the sorting and washing conveyor belt 100. The bottom of the transition buffer hopper 300 is connected to a feeding hose, which is used to allow the pre-separated dried fruit to fall into the mesh opening 701. A vibrating feeder 600 is installed at the top of the side of the washing chamber 200 to distribute the dried fruit into the mesh opening 701. A pneumatic conveying and sterilization structure 500 is installed at the side of the washing chamber 200, which is used to pneumatically convey the washed dried fruit for drying and sterilization. First, the operator evenly spreads the dried fruit to be washed onto the sorting and washing conveyor belt 100. The sorting and washing conveyor belt 100 has a filter structure with different pore sizes inside. During the conveying process, smaller impurities such as mud, sand, and branches are preliminarily separated and discharged from the system through the filter pores, while the dried fruit is conveyed to the transition buffer hopper 300 at the end. This achieves preliminary purification of the raw materials, laying the foundation for subsequent fine washing. Next, the feeding hose at the bottom of the over-buffered hopper 300 guides the dried fruit into the cleaning chamber 200. The cleaning chamber 200 has a multi-layered structure, with each layer equipped with a mesh frame assembly 700. This allows the dried fruit to fall sequentially into the hexagonal mesh openings 701 of the mesh frame assembly 700 under gravity. Simultaneously, the vibrating feeder 600 installed at the top of the cleaning chamber 200 begins operation, generating high-frequency micro-vibrations. This vibration acts on the entire mesh frame assembly 700, leveling and evenly distributing any dried fruit that fails to fall accurately into the mesh openings 701, ensuring that each mesh opening 701 holds an independent dried fruit, effectively preventing accumulation and collisions during the cleaning process. Afterward, once the dried fruit is in place in the mesh openings 701, the microbubble generator 110 integrated at the bottom of the mesh frame assembly 700 begins operation, releasing a large number of fine, uniform bubbles from the microporous aeration head. These bubbles rise and adhere tightly to the rough surface of the dried fruit, thus significantly reducing the overall apparent density of the dried fruit and providing it with stable auxiliary buoyancy.In this state, the dried fruit is gently supported by three elastic protrusions 703 on the edge of the mesh opening 701, presenting an ideal semi-floating posture with the upper half above the water surface and the lower half submerged. The elastic protrusions 703 are made of food-grade silicone, with an embedded elastic spring 702 and a smooth, rounded curved surface 704 at their front ends. This allows the protrusions to elastically deform according to the size of different dried fruits, achieving adaptive clamping. This ensures that the dried fruit will not fall off during subsequent rotational washing and completely avoids damage that may be caused by rigid compression. Subsequently, the rotational drive washing assembly 800 is activated. Its airflow nozzles spray directional airflow, impacting the portion of the dried fruit above the water surface.

[0036] Preferred, according to Figure 4 and Figure 6As shown, the flow guiding component 120 is installed at the bottom of the mesh opening 701. The flow guiding component 120 includes three flow guiding trough plates 122, which are centrally symmetrically distributed with the center of the mesh opening 701 as the origin. A rotating joint 121 is installed on the top of the flow guiding trough plate 122, which rotates on the bottom surface of the mesh opening 701. A groove 123 is opened inside the flow guiding trough plate 122. After the above equipment is started and water is injected, the water in the cleaning chamber 200 is in a relatively static or horizontal state. At this time, the dried fruit is flexibly fixed by the elastic protrusion 703 and is in a semi-floating state. In order to break this static state and create a dynamic cleaning environment for the dried fruit, the flow guiding component 120 begins to function. That is, the water flow begins to flow through the bottom area of ​​the mesh opening 701 under the drive of the circulating pump or under the impact of the external spray. Next, the water flowing through the bottom of the mesh 701 is captured and guided by three centrally symmetrically distributed guide vanes 122. The rotating joints 121 at the top of each guide vane 122 allow for slight adaptive deflection under the impact of the water flow. This ensures that the guide vanes 122 are not rigid, fixed obstacles, but can automatically adjust to an optimal angle of attack based on the initial direction and velocity of the water flow, thereby minimizing flow resistance and efficiently collecting the disordered water flow. The collected water then enters the channels formed on the surface of the guide vanes 122. The cross-sectional shape and orientation of the guide vanes 122 determine the final shape of the water flow. All three channels are arc-shaped channels facing the same tangential direction of rotation. When the water flows through these narrow channels with specific curvature, according to fluid dynamics principles, its velocity increases, its flow direction is uniformly changed, and three high-speed tangential water flows in the same direction are ejected from the three symmetrical points. Next, these three tangential water flows converge directly below the mesh opening 701, coupling and superimposing to form a stable and uniform rotating vortex field. The core axis of this vortex is directly aligned with the center of the dried fruit. The fluid shear force and rotational torque generated by the vortex act directly on the lower half of the dried fruit submerged in water, exposing the entire surface of the dried fruit, including all wrinkles and depressions. Simultaneously, the airflow nozzles of the rotating drive cleaning assembly 800 apply a tangential thrust in the same direction to the portion of the dried fruit exposed above the water. Under the synergistic effect of these dual driving forces—the push of the water flow below and the blowing of the airflow above—the dried fruit overcomes the static friction with the elastic protrusion 703 and begins to rotate smoothly and continuously around its central axis. Throughout the cleaning process, since the vortex generated by the flow guiding assembly 120 originates from the water flow itself, its power is continuous. The rotation speed of the dried fruit can be precisely controlled by adjusting the power of the circulating pump or the flow rate of the spray water, ensuring that both the lighter raisins and the slightly heavier plums can achieve the right rotation speed, which guarantees the cleaning effect while preventing them from being thrown off due to excessive rotation speed.(That is, the rotating vortex generated by the bottom guide component 120 forms the main driving torque on the water-immersed part of the dried fruit, while the air or water tangential force applied by the top rotating drive cleaning component 800 forms an auxiliary driving torque on the exposed part of the dried fruit and performs precise cleaning. By utilizing the two driving forces from different directions working together in the flexible constraint space formed by at least three elastic protrusions 703, the static friction between the dried fruit and the protrusions is overcome, and the dried fruit is driven to rotate smoothly and continuously around its own axis. This creates a top-and-bottom clamping and rigid-flexible driving operation, ensuring that the dried fruit is cleaned evenly without dead angles under the premise of almost zero rigid extrusion and collision, fundamentally solving the problem of the dried fruit being easily damaged during the cleaning process.)

[0037] Further preferred, based on Figure 4 and Figure 5As shown, the rotary drive cleaning assembly 800 includes an airflow nozzle and a waterflow nozzle 803, configured to apply a tangential force to the dried fruit, driving the dried fruit to rotate on the water surface and cleaning its surface. The rotary drive cleaning assembly 800 is located inside the cleaning chamber 200 and above the mesh opening 701. Both the airflow nozzle and the waterflow nozzle 803 have at least three layers of air jets and spray heads with different spray angles, designed for the same cleaning area. A double-chamber end is mounted on the side of the airflow nozzle and the waterflow nozzle 803. An electrically rotating structure 802 is mounted on the side of the double-chamber end. A guide plate 801 is located on the top of the electrically rotating structure 802, and the guide plate 801 is connected to an external filter purification pump box and an air pump, respectively. The airflow nozzles and water flow nozzles 803 consist of an upper spray head, a middle spray head, and a lower spray head. The upper spray head is configured to rinse the exposed surface of the dried fruit at a downward angle of 35°-55°, the middle spray head is configured to rinse the water-to-dried surface of the dried fruit horizontally, and the lower spray head is configured to rinse the submerged surface of the dried fruit through the gaps in the mesh opening 701 at an upward angle of 25°-35°. An intelligent controller includes an AI image recognition unit and a PLC controller. The AI ​​image recognition unit is used to identify the type and quantity of dried fruit in real time. The PLC controller is connected to the AI ​​image recognition unit, airflow nozzles, and water flow nozzles 803, and is used to dynamically adjust the spray pressure of the corresponding airflow nozzles and water flow nozzles based on the recognition results. When the mesh opening 701 carrying the dried fruit is in operation, the AI ​​image recognition unit in the intelligent controller is activated. The AI ​​image recognition unit captures real-time images of the dried fruit located within the mesh opening 701 using a high-resolution industrial camera. Through real-time image analysis, the specific type of dried fruit at the current workstation can be accurately identified (e.g., whether it's a soft, wrinkled raisin or a relatively firm prune). Simultaneously, the quantity and distribution of dried fruit within the mesh port 701 are counted. The AI ​​image recognition unit then transmits the identification results (such as the type and size of the dried fruit) to the PLC controller, which has a pre-stored database of optimized cleaning parameters for different types of dried fruit. Based on the received information, the PLC controller immediately makes a decision and sends instructions to the rotary drive cleaning assembly 800. For raisins with fragile, easily damaged skin, the PLC controller instructs the airflow nozzles and water nozzles 803 to use lower spray pressure and may appropriately increase the airflow ratio to drive their rotation more gently. For prunes with thick flesh and strong surface adhesion, the PLC controller instructs higher water pressure and a specific cleaning angle to ensure cleaning effectiveness while airflow assists in ensuring stable rotation. Afterward, the rotary drive cleaning assembly 800 begins the cleaning operation, forming a three-dimensional cleaning matrix. The upper-level jet nozzles, under the control of the PLC controller, eject a directional, controllable stream of clean air. This airflow impacts the portion of the dried fruit protruding from the water surface at a certain tangential angle, providing the initial rotational driving force that avoids direct contact with the water.Simultaneously, the electrically rotating structure 802 installed on the side of the component begins to operate, driving the airflow nozzles and water flow nozzles 803 to deflect at an angle. This allows the spray angles of the airflow nozzles and water flow nozzles 803 to be dynamically adjusted within a certain range, ensuring that regardless of the initial position of the dried fruit in the mesh opening 701, the airflow can act most effectively on the dried fruit, causing it to start smoothly and accelerate its rotation. Then, after the dried fruit begins to rotate, the three layers of spray heads start simultaneously, providing a comprehensive cleaning of the dried fruit from different angles. The upper spray head, at a downward angle of 35°-55°, rinses the upper part of the dried fruit completely exposed to the air from top to bottom, effectively washing away floating dust and light impurities. The middle spray head, in a horizontal direction, precisely sprays the equatorial region where the dried fruit meets the water surface. Due to surface tension and soaking, this area often has more stubborn dirt or sugary sticky substances adhering to it; the powerful horizontal rinsing can most effectively remove them. Then, the lower spray head, at an elevation angle of 25°-35°, sprays the cleaning solution upwards through the gaps at the bottom of the mesh 701 onto the lower half of the dried fruit submerged in water. This upward-blowing and downward-rushing action, combined with the vortex generated by the bottom guide component 120, ensures that the submerged portion of the dried fruit also experiences sufficient fluid shearing, achieving thorough cleaning. Throughout the cleaning process, the dual-chamber design ensures the independence and purity of the air and water paths, drawing media from an external air pump and a filter purification pump box, respectively. Based on preset programs and AI feedback, the PLC controller can not only adjust the overall pressure but also dynamically fine-tune the opening and closing combinations and spray time ratios of the three-layer spray head and airflow nozzles. For example, when the AI ​​image recognition unit identifies that a batch of dried fruit has heavy surface stains, the action time of the middle layer horizontal spray can be appropriately extended; or when insufficient rotation speed of the dried fruit is detected, the pressure of the upper airflow can be instantly increased. This real-time feedback and adjustment mechanism ensures optimized cleaning results and high energy efficiency.

[0038] In the further plan, according to Figure 3 , Figure 4 , Figure 8 and Figure 9As shown, the conveying assembly 900 is installed at the bottom end or the top end of the mesh opening 701. The conveying assembly 900 includes a conveying mesh belt 901 disposed in the chamber. The surface of the conveying mesh belt 901 is provided with holes 902 for generating microbubbles that adhere to the surface of the dried fruit to pass through. A mounting surface 903 is provided on the side of the surface of the conveying mesh belt 901 near the holes 902. A cleaning rotating assembly 130 is installed on the surface of the mounting surface 903. The cleaning rotating assembly 130 includes a drive servo motor 131. A drive toothed belt structure 132 is connected to the top output end of the drive servo motor 131. A rotating gear 134 is meshed inside the toothed belt of the drive toothed belt structure 132. A tension control structure 133 is installed on the side of the toothed belt. A waterproof pressurized air chamber 135 is installed at the center top of the rotating gear 134. The side end of the waterproof pressurized air chamber 135 is connected to an external air pump. A rotating brush 136 is installed at the top of the waterproof pressurized air chamber 135, and a vision sensor is embedded in the surface of the rotating brush 136. The microbubble generator 110 includes a microporous aeration head located at the bottom of the mesh frame assembly 700, used to generate microbubbles that adhere to the surface of the dried fruit, helping the dried fruit maintain a semi-floating state. First, after the dried fruit completes the cleaning of the previous station... The conveyor belt 901 can be flexibly positioned below the mesh opening 701 to clean the bottom of the dried fruit inside the mesh opening 701 using rotating brushes 136, or positioned above the mesh opening 701 for suspended transport, demonstrating a high degree of flexibility in equipment layout. During transport, microbubbles continuously generated from the microporous aeration heads installed at the bottom of the mesh opening 701 rise freely and smoothly pass through the specially opened holes 902 on the surface of the conveyor belt 901, adhering to the surface of the dried fruit to continue providing auxiliary buoyancy, preventing bubbles from accumulating at the bottom and ensuring a stable fluid environment. Next, when the carrying cleaning rotating assembly 130 is transported to a specific cleaning and inspection station, the drive servo motor 131 starts, transmitting power through the precision drive toothed belt structure 132. Meanwhile, the tension control structure 133 ensures that the drive toothed belt structure 132 maintains optimal tension at all times, preventing slippage or jumping and ensuring smooth and precise power transmission. The power is then transmitted via a meshing rotating gear 134 to the waterproof pressurized air chamber 135 and the rotating brush 136 located at its top. This causes the rotating brush 136 to rotate under the drive of the servo motor 131. Its bristles contact the bottom or top surface of the mesh opening 701. During rotation, the rotating brush 136 effectively and gently brushes the bottom or top of the dried fruit. Simultaneously, an external air pump connected to the waterproof pressurized air chamber 135 continuously supplies clean compressed air into it. This allows the waterproof pressurized air chamber 135 to expand upwards based on feedback from a visual sensor (capturing an image of the dried fruit), causing the rotating brush 136 to contact the surface of the dried fruit, resulting in a better cleaning effect.

[0039] The wiring diagram of the vision sensor in this invention is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the vision sensor will not be explained in detail.
