Description

Technical Field

[0001] The invention belongs to the technical field of temperature monitoring and relates to vinegar slice drying equipment with real-time intelligent control. Background Art

[0002] After the vinegar slice process, the vinegar slices need to be dried by a dryer to make them suitable for the next stage of the process. From a thermodynamic point of view, during the drying process, the heat in the drying hot air is transferred to the vinegar slices through heat conduction and convection heat transfer, thereby achieving the purpose of accelerating the evaporation of water in the wet vinegar slices.

[0003] At present, the dryer is equipped with four heating zones, and a steam coil component is installed in each heating zone. The hot steam heats the cold air to generate hot air, thereby removing the moisture in the wet vinegar slices and obtaining drier vinegar slices. The residual hot and humid air generated after the hot air heats the vinegar slices still has a high heat content, but most companies now directly discharge the residual hot and humid air into the atmosphere, which causes a large amount of heat loss. At present, there is no measurement of the humidity, temperature and other parameters of the discharged residual hot and humid air. In addition, during the drying stage of the vinegar slices, the wind field and thermal field inside the vinegar slice dryer are not evaluated and measured, and the installation position of field instruments such as thermometers is based on experience and has great uncertainty.

[0004] In summary, in order to facilitate real-time monitoring of the temperature of each part in the dryer and effectively dry the residual hot and humid air generated after drying the wet vinegar slices, a vinegar slice dryer device with real-time intelligent control is proposed.

[0021] 2. Optimize steam production performance: This equipment can automatically adjust the power of the PID-controlled heating tube according to the hot air required for drying wet vinegar slices, so that the steam coil will not waste excess steam while generating enough steam to heat the cold air, thus optimizing the steam production performance and achieving the best vinegar slice drying effect, thereby ensuring that the drying efficiency of the entire equipment for wet vinegar slices is always in the best state;

[0025] 6. Improve system adaptability: Since the power of the PID-controlled steam heating tube can be adjusted according to the actual amount of steam required, the automatic adjustment of the power of the PID-controlled steam heating tube can automatically adjust the amount of steam generated, thereby improving the system's adaptability to various environments. In various environments, it can ensure that the amount of steam generated by the steam coil is necessary to heat the preheated air, thereby achieving the best drying effect for wet vinegar slices and keeping the entire wet vinegar slice drying system running efficiently.

[0039] Please see attached Figure 1-6As shown, the present invention provides an intelligent temperature measuring vinegar slice dryer device for drying vinegar slices after the vinegar slice process; in the drying stage, 4kg steam and 10kg steam are used to heat the ambient air step by step to make it into dry hot air at about 150°C, and the dry hot air flows through the wet vinegar slices from top to bottom, taking away a large amount of moisture in the vinegar slices. The intelligent temperature measuring vinegar slice dryer device includes a shell 1, a feed zone 2, a heating zone 3 and a discharge zone 4, wherein the feed zone 2 and the discharge port 3 are respectively arranged on the shell 1, and the heating zone 4 is arranged inside the shell 1; wherein the shell has an air inlet and an air outlet, and the internal air flow duct is interconnected with the air inlet and the air outlet; the feed zone 4 includes a steam inlet pipeline system component, and the discharge zone 3 includes an exhaust pipeline system component; the steam inlet pipeline system component is arranged at the bottom of the shell 1, and the exhaust pipeline system component is arranged at the top of the shell 1, and the heating zone 4 is arranged. A steam coil component 41 is provided, and the steam coil component 41 includes a steam heating pipe 41; steam flows in through the steam inlet pipe system component and then enters and flows through the steam coil component, and then is discharged through the exhaust pipe system component, so that it can fully heat the ambient air in the entire equipment shell 1, and generate enough dry hot air, so that the dry hot air formed by the fully heated ambient air flows through the wet vinegar slices from top to bottom, thereby taking away a large amount of moisture in the wet vinegar slices. At this time, the dry hot air is converted into high-temperature and high-humidity residual wet hot air, so that the wet vinegar slices are fully dried.

[0040] In order to achieve the above-mentioned purpose, the present invention sets a temperature sensor 5 in the heating zone in the shell 1. In order to facilitate further understanding of the structural principle of the present device, the heating zone 4 is divided into four heating zones, and a temperature sensor 5 is set in the cavity of each heating zone 4 for real-time monitoring of the hot air temperature in the inner cavity of the heating zone 4.

[0041] In this embodiment, the temperature sensor 5 is a DS18B20 digital temperature sensor, which can accurately reflect the temperature of the hot air generated by the steam generated by the steam coil. The real-time temperature is then transmitted to the main control chip, and then transmitted to the LCD display screen for display. At the same time, the data is remotely sent to the central control room by the data transmission unit, and the computer in the central control room will regulate the power of the PID control (proportional-integral-differential control) heating tube.

[0042] It should be noted that the DS18B20 in this embodiment is a digital temperature sensor produced by Maxim Integrated. It is a widely used temperature sensor, particularly suitable for digital temperature measurement applications. The DS18B20 sensor has very low power consumption during the measurement process, so it is suitable for applications that require long-term operation or battery power. It is suitable for the use of this system to achieve energy saving and maximize the drying efficiency of wet vinegar slices. The DS18B20 sensor uses a single bus protocol for communication, so only one data line is needed to communicate with the main control device, simplifying wiring and connection. This temperature sensor has strong anti-interference ability, and its measurement range is from -55°C to +165°C, with an accuracy of up to ±0.5°C.

[0043] In this embodiment, in order to realize the data processing monitored by the temperature sensor 5, a controller 6 is also introduced, and the controller 6 is arranged on the dryer device; the controller 6 can calculate the required optimal amount of hot steam and the power required for the steam heating pipe according to the data received from the temperature sensor, and adjust the power of the steam heating pipe 41 to make the steam coil reach the most appropriate power, so that the generated steam can fully heat the preheated air, so that the wet vinegar slices can be fully dried.

[0044] The present invention uses this system to use STM32 type microcontroller, and STM32 microcontroller is the microcontroller of the ARM Cortex-M series processor core launched by STMicroelectronics. They are powerful, peripheral-rich, and low-power, and are widely used in the fields of industrial control, consumer electronics, and communication equipment. The controller model used in the present invention is Cortex-M4, and this model controller provides high performance, low power consumption, and abundant peripheral interfaces, including general purpose input and output (GPIO), timer, serial communication interface (UART, SPI, I2C), analog-digital converter (ADC), digital-analog converter (DAC), PWM output, USB interface, Ethernet controller, etc., can meet various application requirements.

[0045] In this embodiment, the controller 6 is electrically connected to the steam heating pipe 41. Under the control of the controller 6, the steam heating pipe 41 fully heats the ambient air in the entire shell 1 and generates enough dry hot air to fully dry the wet vinegar slices; and according to the instructions of the controller 6, the steam heating pipe 41 can adjust its own heating power within a range to adapt to different steam generation requirements.

[0046] In order to control the steam heating pipe 41, the present invention uses a PID (proportional-integral-differential) control algorithm to achieve accurate temperature control of the steam heating pipe 41; the PID algorithm consists of three parts: proportional (P), integral (I) and differential (D). Proportional control takes into account the current error, and the error value is multiplied by a positive constant Kp (representing the proportion). For details, please refer to Figure 5 , Figure 5 It is a PID algorithm flow chart. The target temperature set by the user and the temperature of the environment measured by the temperature sensor can be compared to calculate the temperature difference. The temperature difference is calculated through integration, differentiation and proportional operations to calculate the adjustment amount. The steam heating tube 41 is controlled according to the adjustment amount to achieve the optimal requirement. The key factor of the present invention is the variable power of the steam heating tube, and the variable to be controlled is the temperature of the dry hot air required for drying the wet vinegar slices. The design scheme measures the temperature of the hot air in the heating zone cavity by installing a temperature sensor 5, and transmits the real-time temperature data of the measured place to the control terminal of the STM32 microcontroller. The algorithm language is written to control the real-time power of the variable power steam heating tube, thereby changing the amount of steam generated by the steam coil, so that the preheated air can be fully heated without causing the steam coil to generate too much air; for details, please refer to Figure 4 The main program flow chart in .

[0047] It should be noted that the working principle of the present invention is based on intelligent control and temperature feedback mechanism, which is used to optimize the steam generation rate of the steam coil in the heating zone, which not only improves the energy efficiency and performance of the entire wet vinegar slice drying system, but also reduces the operating cost and maintenance requirements. At the same time, the demand for electric energy is minimized, and the pollution to the environment is also minimized, which provides a more reliable implementation plan for the industrial drying of wet vinegar slices and various other materials.

[0048] At the same time, for the convenience of operation, a central control room 7 is also provided on the housing 1, and the central control room 7 is used to control the function adjustment of the dryer equipment. Among them, a display screen 71 and a multi-function control button 72 are provided on the central control room 7; the display screen and the multi-function control button 71 are electrically connected to the controller 6. In this embodiment, the display screen 71 adopts an LCD touch screen, which is used to control and display the temperature, time, date and required information in real time; the multi-function control button 72 is used to adjust the functional instructions of the equipment, such as temperature adjustment, heating time adjustment and other required adjustment instructions.

[0049] The working principle of the present invention is as follows:

[0050] (1) Temperature monitoring: The temperature sensor 5 in the system is one of the key components. These temperature sensors 5 are installed in the four heating zones of the vinegar slice dryer. Since the temperature sensor 5 needs to monitor the temperature in the cavity of the heating zone in real time, the sensing element of the temperature sensor 5 must extend into the cavity of the heating zone of the dryer to monitor the temperature of the dry hot air generated by the air preheated by the steam heating tube 41 in real time; these temperature data reflect the current working status of the PID control heating tube.

[0051] (2) Data transmission unit: The monitored temperature data will be transmitted to the STM32 controller in real time. This data is an important input in the control system decision-making process.

[0052] (3) Intelligent control algorithm: The controller 6 has an advanced algorithm built in to process the received temperature data. Based on this data, the algorithm will calculate the optimal power required for the current PID control heating tube for drying the wet vinegar slices. The design of the algorithm takes into account not only the temperature data, but also the preset working parameters, historical performance data, and possible environmental changes. By designing a software program, the control system can set the threshold through the program. If the power of the PID control steam heating tube 41 is higher than the set threshold, the PID control heating tube is at risk of being damaged. At this time, in order to protect the PID steam heating tube 41 and prevent equipment damage, the system will automatically alarm, and the alarm information will be displayed on the display screen; if the system is connected to an audio device, an alarm will sound to alert the on-site staff. If this system is connected to the company's kinetic energy operation and maintenance platform via the Internet, when an alarm event occurs, the system will send the alarm information to the relevant person in charge so that the person in charge can handle the emergency alarm.

[0053] (4) PID control steam heating tube 41 power adjustment: According to the instruction of the controller 6, the power of the PID control steam heating tube 41 will be adjusted accordingly. If the temperature sensor 5 detects that the temperature of the hot air in the cavity of the vinegar slice dryer heating zone is too high, then under the condition of fully drying the vinegar slices, some hot steam is wasted, which means that the power of the PID control steam heating tube is too high, which causes some waste of electric energy; on the contrary, if the temperature sensor 5 detects that the temperature of the hot air in the cavity of the vinegar slice dryer heating zone is too low, it means that the power of the PID control heating tube is too low. At this time, the power of the PID control heating tube 74 should be increased in time to increase the amount of steam generated by the steam coil, so that a sufficient amount of preheated air is heated into hot air for drying the vinegar slices, so that the wet vinegar slices can be fully dried.

[0054] (5) Continuous optimization and feedback: The system continuously monitors the temperature data and adjusts the power of the PID-controlled steam heating tube, and constantly adjusts the power of the PID-controlled heating tube so that it can reach a relatively stable power, thereby ensuring that the generated steam can fully heat the preheated air, and the generated hot air can fully dry the wet vinegar slices. This method can make the signal transmitted by the temperature sensor 5 respond quickly, and adjust the power of the PID-controlled steam heating tube 41 in real time, ensuring that the entire drying system can always maintain the lowest energy consumption and the best wet vinegar slice drying performance.

[0055] In general, the present invention utilizes a method combining temperature data and an intelligent control algorithm to dynamically adjust the power of the PID-controlled steam heating tube to adapt to the ever-changing steam demand; this method not only improves energy efficiency, but also ensures that the system's effect on vinegar slices is always maintained in the best state; through this intelligent and adaptive working mechanism, the present invention significantly improves the overall performance and economic benefits of the vinegar slice dryer.

[0056] The above-mentioned related explanations and descriptions of the embodiments are for the convenience of those skilled in the art to understand and apply the present invention. It is obvious that those familiar with the art can easily make various modifications to these contents and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above-mentioned related explanations and descriptions of the embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
