Description

Technical Field

[0001] The invention belongs to the technical field of pineapple bean production, and in particular relates to a surface spray device for pineapple bean production. Background Art

[0002] During the production of pineapple beans, the roasting stage significantly impacts their quality. Surface cracking is a common problem during roasting, and surface spraying technology has emerged to prevent this cracking. By evenly spraying a specific liquid on the surface of the beans, the moisture content of the beans can be effectively adjusted, thereby reducing surface cracking caused by excessive water evaporation. The spray liquid, typically composed of water, humectants, or certain natural ingredients, forms a protective film on the surface of the beans, slowing water evaporation and ensuring the beans maintain an appropriate level of moisture during roasting. Spraying technology not only helps prevent excessive surface expansion and water loss during high-temperature roasting, thus preventing cracking, but also ensures uniform heating of the beans, preventing over-drying during roasting. Furthermore, surface spraying technology allows precise control of the surface temperature and humidity of the beans by adjusting the spray volume and timing. This technology significantly improves the appearance of the beans, maintaining an intact and smooth surface after roasting, enhancing their market appeal and consumer purchases. In general, the use of surface spray technology in the production process of pineapple beans can not only effectively prevent surface cracking during the roasting process, but also improve the texture and durability of the product, thereby improving the overall quality and production efficiency of pineapple beans.

[0003] Existing surface spraying is difficult to achieve a uniform spraying effect, and it is easy to cause excessive or insufficient local spraying. Summary of the Invention

[0004] In view of this, the present invention provides a surface spray device for pineapple bean production, which can solve the problem that the existing surface spray is difficult to achieve a uniform spraying effect and easily causes excessive or insufficient local spraying.

[0005] The present invention is achieved in that: The invention provides a surface spray device for producing pineapple beans, which comprises a water pipe, a nozzle, a water outlet, a liquid supply component, a linkage component and a conveyor belt. The water pipe comprises multiple sections, wherein a plurality of nozzles are arranged inside a transverse pipe section located in a middle position, one side of the nozzle is arranged in an arc-shaped structure, and a plurality of water outlets are distributed on the arc-shaped structure. The water output of the water outlets sprayed on the surface of the pineapple beans transported on the conveyor belt is normally distributed on a plane, and the water output of the sprays from adjacent water outlets presents an opposite normal distribution curve. One end of the water pipe is connected to the liquid supply component, and the liquid supply component and the conveyor belt are linked by the linkage component for feedback adjustment, so that the spray output of the surface spray device is positively correlated with the conveying speed of the conveyor belt.

[0006] The surface spray device for pineapple bean production provided by the present invention has the following technical effects: multiple nozzles are disposed within a central transverse pipe section, and one side of the nozzles is an arc-shaped structure with multiple water outlets distributed thereon. This structure ensures that the spray is sprayed onto the pineapple beans on the conveyor belt in a relatively uniform and concentrated manner. The water output of the water outlets is normally distributed on a plane, and the water output of the spray from adjacent water outlets follows opposite normal distribution curves, which means that the spray is more evenly distributed, effectively covering the surface of the pineapple beans and avoiding excessive or insufficient localized spraying.

[0007] On the basis of the above-mentioned technical scheme, a kind of pineapple bean production surface spray device of the present invention can also do the following improvement: The water pipe includes a water inlet section and a water outlet section, the water inlet section and the water outlet section are respectively connected to the two sides of the transverse pipe section in opposite directions and are both arranged perpendicular to the transverse pipe section; the interior of the water inlet section is set as a double-layer structure, and a condensation section is provided on the side away from the nozzle. The two sides of the condensation section form a sealed pipe with the condensation pipe, and condensed water flows inside. A condenser and a liquid pump are connected through the middle part. The condenser is used to cool the condensed water flowing through, and the liquid pump is used to circulate the condensed water inside the sealed pipe; The position where the water pipe is connected to the nozzle near the pipe and is connected to the nozzle is provided with a double baffle connected at the end. The position where the double baffle is connected and the position where the water pipe and the nozzle are connected are hinged to a position away from the liquid supply component along the water flow direction; the double baffles are set at an obtuse angle, and the width of the baffle inside the water pipe is slightly smaller than the inner diameter of the pipe near the nozzle of the water pipe; the baffle size of the double baffle at the position of the nozzle port is smaller than the size at the port position, which is used to form a diversion when the water flow inside the water pipe is too large.

[0008] The benefits of this improved solution include: within the double-layer structure of the water inlet section, the condensation section is designed to cool the condensed water flowing through it. Combined with a liquid pump to circulate the condensed water, this regulates the temperature of the liquid flowing through the pipes, preventing high temperatures from affecting the spray effect or causing damage to the equipment. This temperature regulation function is particularly important when handling temperature-sensitive liquids.

[0009] Furthermore, the double baffle is a double-layer structure, the flexible layer is attached to the top of the rigid layer and is in direct contact with the water flow, and the flexible part is fixedly connected to the rigid part as a whole; the edge position of the double baffle is set as a chamfered structure to disperse the impact force of the water flow.

[0010] The benefits of this improved solution include: The dual baffles located at the junction of the water pipe and nozzle provide a diversion effect. When the water flow is too strong, they effectively disperse the flow, preventing it from impacting the nozzle and extending the nozzle's service life. The chamfered edges further disperse the impact of the water flow, reducing damage to the nozzle.

[0011] Furthermore, a pressurized swirl structure is provided inside the water outlet, and the pressurized swirl structure includes a liquid inlet end and a liquid outlet end, and the cross-sectional area of ​​the liquid inlet is larger than the cross-sectional area of ​​the liquid outlet to achieve initial acceleration of the fluid; two symmetrical conical nozzles are designed inside the liquid outlet, and the tips of the two conical nozzles are close to each other and connected to form a final injection channel for the fluid; the fluid enters the interior of the water outlet from the liquid inlet, and due to the large cross-sectional area of ​​the liquid inlet, the fluid has a relatively low flow rate and a high pressure here. When the fluid flows to the liquid outlet, the flow rate of the fluid will increase sharply due to the sudden decrease in the cross-sectional area of ​​the liquid outlet; the two symmetrical conical nozzles are used to further focus the fluid, so that the fluid has a higher speed and a more concentrated impact force when it is ejected, thereby achieving uniform and efficient injection of the working surface.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the pressurized swirl structure in the water outlet changes the flow rate and pressure of the fluid, so that the fluid has a higher speed and more concentrated impact force when it is sprayed out, thereby making the spray more uniform, better covering the surface of the pineapple beans, and improving the spray effect.

[0013] Furthermore, the spray coverage area of ​​the multiple nozzles is the same as the area of ​​the conveyor belt passing through the water pipe position per unit time, and the spray areas of adjacent nozzles overlap by less than 3 mm to ensure the uniformity of the spray area.

[0014] Furthermore, a piezoelectric crystal is provided inside the nozzle for generating ultrasonic waves through high-frequency vibration. The liquid is broken into fine droplets under the action of ultrasonic waves to form a spray; the piezoelectric chip adopts a "sandwich" structure, consisting of two pieces of piezoelectric ceramics sandwiched between an elastic substrate, and its surface is set as a microporous structure, which is used to split the liquid into fine droplets, thereby forming a uniform spray.

[0015] The beneficial effect of this improved solution is that the piezoelectric crystal inside the nozzle generates ultrasonic waves through high-frequency vibration, breaking the liquid into fine droplets and forming a uniform spray. This ultrasonic spray technology can improve the fineness and uniformity of the spray, further optimizing the spray effect.

[0016] Furthermore, the liquid supply component includes a delivery pump and a delivery pipe, the delivery pump includes a shell, a feed port, a delivery port, a wire sealing plug structure and an extraction pump, the extraction pump is arranged inside the shell, and a liquid flow cavity is provided between the shell and the extraction pump, one end of the liquid cavity is connected to the feed port, and the other end is connected to the delivery port, the feed port is used to extract the liquid inside the pipeline into the delivery pump, and the delivery port is used to deliver liquid to the water pipe; the wire sealing plug structure is arranged on one side inside the shell for storing wires.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the feed port and the delivery port of the delivery pump can efficiently extract and deliver the liquid into the water pipe, and the wire sealing plug structure is used to store the wires to ensure the normal operation of the delivery pump.

[0018] Furthermore, an electromagnetic control valve is provided inside the water pipe, the electromagnetic control valve includes a valve and an electromagnetic coil portion connected to the valve, the valve includes a valve sleeve, a spring, a valve core and a push rod, the spring, the valve core and the push rod are sequentially arranged inside the valve sleeve, the valve core and the push rod are integrally formed, an output port and a return port are provided on the side wall of the valve sleeve, the output port is composed of four square openings evenly distributed along the circumferential direction, a radially outwardly extending protrusion matching the output port is provided on the outer side of the valve core; a tubular portion for accommodating a spring is provided at one end of the valve core, the outer diameter of the spring being slightly larger than the outer diameter of the valve core; The electromagnetic coil part consists of a shell, a coil tubular yoke and a plunger, the coil is arranged on the inner side of the shell, the tubular yoke is arranged on the inner circumference of the coil, and the plunger is arranged on the inner side of the tubular yoke; the electromagnetic coil part is used to control the opening and closing of the valve.

[0019] The beneficial effects of this improved solution are: the electromagnetic control valve, which controls the opening and closing of the valve through the electromagnetic coil, can precisely control the liquid flow rate. The coordination of the valve sleeve, spring, valve core, and ejector rod, as well as the design of the output and return ports on the sidewalls of the valve sleeve, enable more flexible and accurate liquid flow regulation.

[0020] Furthermore, the linkage component includes a speed sensor and a controller installed on one side of the conveyor belt, and the controller is used to control the liquid flow rate delivered by the delivery pump of the liquid supply component. The speed monitored by the speed sensor is positively correlated with the liquid flow rate delivered by the delivery pump in a linear function, wherein the constant term of the linear function is measured through multiple experiments.

[0021] The beneficial effects of adopting this improved solution are as follows: a speed sensor can monitor the speed of the conveyor belt and transmit this speed information to a controller. The controller adjusts the liquid flow rate of the delivery pump using a linear function based on changes in the conveyor belt speed, ensuring a positive correlation between the spray volume and the conveyor speed, thereby ensuring the stability and consistency of the spray effect. In this device, the conveyor belt is used to transport pineapple beans. It and the liquid supply assembly are feedback-regulated via a linkage assembly, allowing the spray volume to be adjusted accordingly based on changes in the conveyor speed, ensuring that the spray effect matches the pineapple bean delivery process.

[0022] Furthermore, an anti-backflow component is provided at a position of the water pipe near the water outlet section, and the anti-backflow component includes two parts, namely a direct current part and a curved flow part. The direct current part is arranged in the middle position of the anti-backflow structure, and the curved flow part is arranged on both sides of the direct current part; the curvature of the curved flow part is 160°, and it is connected with the side wall of the direct current part; there are 11 curved flow parts, which are cross-arranged on both sides of the direct current part.

[0023] The beneficial effects of this improved solution are as follows: the design of the backflow prevention component effectively prevents liquid from flowing back through the water pipe, ensuring the normal flow direction of the liquid. The arrangement of the straight and curved sections, particularly the specific curvature and arrangement of the curved sections, creates resistance to reverse flow, further enhancing the backflow prevention effect and ensuring the normal operation of the spray device. Compared with the prior art, the beneficial effects of the surface spray device for pineapple bean production provided by the present invention are: The water pipe design consists of multiple sections, including a transverse section, an inlet section, and an outlet section. Multiple nozzles are installed within the transverse section, with one side of the nozzle adopting an arc-shaped structure. Multiple outlet holes distributed within this arc ensure uniform distribution of the spray across the surface. The water output is normally distributed across the plane, and this regular distribution of the spray volume contributes to a uniform spray effect. The water flow through the well-spaced nozzles and outlet holes creates a uniform spray, optimizing the surface spray effect.

[0024] The liquid supply assembly connects to the water pipe, providing a liquid source and working with the linkage assembly to provide feedback and adjust the spray volume. This linkage mechanism ensures a positive correlation between spray volume and conveyor speed, meaning that as the conveyor speed changes, the spray volume also adjusts accordingly. This assembly ensures automated adjustment of the spray system, improving production line efficiency.

[0025] The linkage assembly includes a speed sensor on the conveyor belt and a controller that adjusts the liquid flow rate to the liquid supply assembly based on the speed sensor data. This linkage mechanism ensures that the spray volume remains consistent with the production line speed, improving production efficiency and product quality.

[0026] A piezoelectric crystal within the nozzle uses ultrasonic waves to transform the liquid into fine droplets, enhancing the spray effect. Furthermore, a pressurized swirl structure within the outlet accelerates the liquid, enhancing the spray effect. This design effectively improves spray uniformity and efficiency, ensuring consistent spray coverage across the pineapple bean surface.

[0027] The water inlet section is designed with a condensation section. The condensed water is cooled by the condenser and circulated with the liquid pump to prevent the spray device from malfunctioning due to high temperature. The condensed water circulation system can reduce the temperature of the equipment, extend the service life of the device and ensure the stability of the spray effect. Double baffles are installed near the nozzle of the water pipe to regulate the water flow and prevent excessive water flow from affecting the spray effect. The baffles ensure a smooth water flow, prevent uneven spraying, and improve the precision of the spray effect.

[0028] The anti-backflow component of the water pipe effectively prevents liquid backflow by configuring bends and straight sections, protecting the normal operation of the equipment. This design ensures that liquid flows only in the intended direction in the system, improving the stability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1: Standard pineapple bean spray production line solution In the standard pineapple bean spray production line, this solution is suitable for large-scale assembly line production and is suitable for spray treatment of pineapple beans in large quantities. The production requirements are relatively simple and stable. The spray device is equipped with multiple evenly distributed nozzles, and the design of the nozzles can be appropriately adjusted according to the requirements of liquid flow and spray effect. The ultrasonic spray technology used can ensure that the droplet size is small and evenly distributed while operating efficiently, thereby achieving fine spraying on the surface of the pineapple beans. The water outlet of each nozzle has a pressurized swirl structure, which not only increases the stability of the spray, but also effectively improves the uniformity and coverage of the spray, so that each pineapple bean can be evenly covered with liquid.

[0041] The device also utilizes an advanced linkage control system, tightly connected to the production line's conveyor belt. A conveyor belt speed sensor monitors production speed in real time and automatically adjusts the spray volume to ensure precise alignment with the production line speed. Furthermore, users can preset the spray flow rate and spraying time for different production batches, flexibly adapting to varying production needs and significantly improving production flexibility and efficiency.

[0042] To further ensure the stability of the spray system during operation, the condensation system utilizes a robust condensate circulation design. This system promptly dissipates heat generated during operation, preventing overheating that could affect efficiency or even damage the equipment. The condenser's temperature control design ensures a stable temperature even under high loads, ensuring long-term stable operation.

[0043] The solution also places great emphasis on backflow prevention. To prevent liquid from flowing back into the equipment, a specially designed backflow prevention component ensures that the liquid always flows along the correct path, avoiding any leakage and unnecessary losses, thereby improving the safety and reliability of the equipment.

[0044] The operation process is also very simple. Before starting the equipment, users can set the spray flow rate and spray duration according to the needs of the specific production batch. Once the production line is started, the spray device automatically adjusts the spray volume based on real-time sensor feedback to keep pace with the production line, achieving automated spray processing.

[0045] During the spray treatment process, the liquid is evenly sprayed on the surface of the pineapple beans, and the tiny droplets evenly cover each pineapple bean, ensuring that the surface of each pineapple bean is evenly treated, thereby improving the efficiency and quality of subsequent processing.

[0046] To ensure long-term stable operation of the equipment, it is necessary to regularly check the working status of the spray device, especially the maintenance of the nozzle, pipes and condensation system. By cleaning the nozzles and pipes in time, you can effectively prevent blockage and extend the service life of the equipment.

[0047] Overall, this solution's advantages lie in its suitability for large-scale production, its high degree of automation, and its ability to effectively improve production efficiency and reduce manual intervention. Furthermore, its uniform spraying effect ensures high production quality, providing a stable, efficient, and reliable solution for large-scale pineapple bean spray treatment.

[0048] Example 2: Small batch high-precision spray production line solution With the growing market demand for high-end, customized products, small-batch high-precision spray production lines have emerged. This embodiment is designed specifically for high-end or customized production needs and is particularly suitable for small-batch production, especially for pineapple bean products that require extremely high spray accuracy and surface treatment.

[0049] The spray device features adjustable nozzles, allowing users to manually adjust the spray angle and range according to production needs. These nozzles, equipped with advanced piezoelectric crystal technology, deliver a stable spray at a minimal flow rate, ensuring even coverage of each pineapple bean with minimal liquid waste. Furthermore, the nozzles utilize a pressurized swirl structure for a more detailed and uniform spray, further enhancing the quality and effectiveness of the spray.

[0050] In this solution, the linkage system not only automatically adjusts the spray volume based on production line speed but also allows for fine-tuning through manual operation. For example, when special processing is required for a particular batch, the user can manually adjust the nozzle angle and spray duration to meet specific needs. This flexible control system greatly facilitates the small-batch production of high-end products and can precisely meet diverse and complex production requirements.

[0051] To address the issue of equipment overheating during high-precision spraying, the condensation system utilizes more efficient temperature control technology. Equipped with a precise temperature controller, the system automatically adjusts the flow rate and temperature of the condensate according to environmental changes. This not only prevents the equipment from overheating during high-precision spraying, but also extends its service life and improves production stability.

[0052] To prevent backflow, the anti-backflow component uses high-temperature resistant materials to prevent the liquid from backflowing due to temperature fluctuations. The anti-backflow valve also has increased sensitivity, ensuring that the liquid always flows in the intended direction during the spray process. This design effectively avoids backflow caused by temperature differences and further improves the reliability of the equipment.

[0053] The operation process is also very convenient. Before starting the machine, users can adjust the spray angle and spray volume according to their specific needs, flexibly setting the parameters of each nozzle. After startup, the machine automatically adjusts the spray volume according to the production line speed, but users can also make manual adjustments at any time during operation to ensure the optimal spray effect.

[0054] During the spraying process, the spray device precisely sprays the liquid onto each pineapple bean according to the set spray parameters. Due to the fine adjustment of the nozzle, the droplet size is uniform and the spray effect is fine, which can fully meet the strict appearance requirements of the high-end market for pineapple beans.

[0055] In addition, regular inspections of the nozzle and condensation system to ensure that the equipment is not affected by any impact during high-precision spraying are also essential maintenance work. In particular, the temperature control of the condensation system needs to be calibrated regularly to ensure its accuracy and reliability.

[0056] Overall, this solution offers the advantage of precise control over spray effects, adapting to flexible and ever-changing production needs, and ensuring consistent quality across batches. It is suitable for small-batch production of high-end products, providing a high-quality, high-precision spray solution for the high-end market.

[0057] Example 3: Pineapple bean spray production line solution under high temperature environment In some special production scenarios, high temperatures and high humidity are often encountered. This environment places higher demands on equipment performance. Therefore, a high-temperature pineapple bean spray production line has emerged, which is particularly suitable for pineapple bean spray processing that requires efficient and stable production under extreme working conditions.

[0058] The spray nozzles are constructed of high-temperature, heat-resistant materials, such as stainless steel alloys, which can withstand the operating pressures of high-temperature environments, ensuring stable operation of the equipment even at high temperatures. The outlet uses a pressurized swirl structure, which maintains high spray stability and effectiveness at high temperatures, reduces liquid loss, and improves spray uniformity, thereby ensuring spray quality and efficiency.

[0059] In such a high-temperature environment, the design of the condensate circulation system is particularly important. This system is equipped with a highly efficient temperature control module that monitors equipment temperature in real time and rapidly reduces temperatures by adjusting the flow and temperature of the condensate. This ensures that the equipment remains in optimal working condition even under prolonged, high-load operation, providing a strong guarantee for stable operation.

[0060] To address the potential impact of temperature fluctuations on liquid flow in high-temperature environments, the design of an anti-backflow system is crucial. This system utilizes high-temperature, corrosion-resistant materials and precise valve control to ensure that liquid flows consistently in the intended direction, preventing backflow caused by temperature differences. This design effectively improves equipment reliability and safety, avoiding unnecessary liquid waste and equipment failures.

[0061] The control system is also equipped with a high-temperature adaptable controller and a more precise temperature monitoring system. This system can stably control the spray flow rate and spraying time even in high-temperature environments, ensuring consistent spray results. This high-precision control capability provides strong support for the stable operation of the equipment in extreme environments.

[0062] When the equipment is started, the condensation system first regulates the liquid temperature and ensures the spray mechanism functions properly in high-temperature environments. Users can manually or automatically adjust the spray flow rate and spray time based on the ambient temperature to ensure the spray effect is not affected even in high temperatures. During the high-temperature spraying process, the spray mechanism operates stably, and the efficient condensate circulation system maintains the equipment temperature, ensuring a uniform and consistent spray effect and optimal surface treatment of the pineapple beans. During extended operation in high-temperature environments, users should regularly inspect the nozzles, condensation system, and backflow prevention components to ensure proper operation. The nozzles and piping should also be cleaned regularly to prevent any blockage or equipment damage caused by high temperatures.

[0063] In short, this solution is suitable for working in extreme environments and can maintain stable equipment operation under high temperature and humidity production conditions. It provides an efficient, reliable, and stable solution for the pineapple bean spray production line operating in high-temperature environments, effectively ensuring smooth production. Specifically, the principles of the present invention are as follows: First, install the water pipe, liquid supply assembly, linkage assembly, and nozzle according to design requirements. Ensure secure connections between all components, especially the connection between the liquid supply assembly and the water pipe, and the linkage assembly and the conveyor. Connect the liquid supply assembly to the liquid source, ensuring that the liquid source is clean and stable to ensure spray quality. Purified water or properly treated liquids can generally be used, and the appropriate liquid should be selected based on production requirements. The controller in the linkage assembly is configured to match the production line speed to ensure that the spray volume is consistent with the conveyor speed. A speed sensor is used to monitor the production line speed in real time, and the controller automatically adjusts the liquid flow rate of the liquid supply assembly. Start the condensing section and condensate circulation system to ensure a stable temperature in the spray device to prevent damage from high temperatures. Regularly check the operating status of the condenser and liquid pump to ensure proper condensate circulation. After starting the spray device, observe the spray performance of the nozzle and water outlet to ensure that the liquid droplets are evenly distributed on the surface of the pineapple beans. If any abnormalities are detected, adjust the water flow rate and nozzle angle to ensure the spray quality meets the requirements.
