Description

Technical Field

[0001] This utility model relates to the field of rice processing, and in particular to an intelligent control system for rice processing. Background Technology

[0002] In the rice processing process, the rice pressure regulation (i.e., whitening pressure control) of the rice milling machine is a core factor affecting the quality of the finished rice. To ensure the quality of milled rice, manual sampling of the milled rice is often performed, followed by testing of the whiteness and appearance (such as broken rice) using a dedicated whiteness meter and appearance inspection instrument. Operators need to manually modify parameters based on the sampling data provided by the inspection laboratory. The initial setting and subsequent adjustment of the processing pressure both require manual intervention, resulting in a long adjustment cycle and a high risk of over-processing or under-processing.

[0003] Furthermore, the data analysis of the whiteness meter and the appearance inspection instrument in the testing room is independent, lacking a real-time linkage mechanism. For example, when the whiteness meter detects a low whiteness value, it cannot immediately trigger pressure adjustment and must wait for manual confirmation before operation, resulting in a delayed response. Summary of the Invention

[0016] Figure 2 This is a schematic diagram of the structure at the discharge port of the rice milling machine. Detailed Implementation

[0017] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0018] This invention proposes an intelligent control system for rice processing, which achieves automated dynamic adjustment of the rice processing process through the intelligent collaborative control of an online whiteness meter, an appearance inspection instrument, and a pressure regulation unit.

[0019] Please see Figure 1 This utility model discloses an intelligent control system for rice processing, including a control module and an adjustment module connected to the control module. The control module can compare the whiteness value and appearance quality (such as broken rice rate) of the rice after milling with the target value, and send an adjustment command to the adjustment module according to the deviation between the two. The adjustment module can automatically adjust according to the set value and a pre-set adjustment strategy based on the received adjustment command until the target requirement is met, thus realizing real-time dynamic automatic adjustment.

[0020] Specifically, the control module includes a main control unit and a data acquisition unit connected to the main control unit. The main control unit includes an appearance inspection instrument, and the data acquisition unit includes an online whiteness meter. The appearance inspection instrument includes a microprocessor and a high-speed camera. The appearance inspection instrument and the online whiteness meter can be configured inside the discharge port. The appearance inspection instrument is a device integrating a microprocessor and a high-speed camera. The high-speed camera can capture images during the flow of rice grains. Simultaneously, the online whiteness meter is connected to the appearance inspection instrument via a serial communication interface, transmitting the whiteness value to the appearance inspection instrument for data analysis. The appearance inspection instrument pre-stores whiteness target values ​​and appearance accuracy target values ​​(such as broken rice rate). The microprocessor compares the real-time acquired whiteness and accuracy values ​​with the corresponding target values, calculates the corresponding deviation, and issues a corresponding adjustment signal based on the deviation. The appearance inspection instrument is wiredly connected to the pressure control unit, transmitting the adjustment signal to the adjustment module.

[0021] In one embodiment, the appearance inspection device may also be a device integrating a microcontroller and a high-speed camera.

[0022] The adjustment module includes a pressure control unit and a pressure adjustment unit for adjusting the opening and closing of the discharge port baffle. The pressure control unit controls the pressure adjustment unit according to the control commands from the main control unit. Further, the pressure adjustment unit also includes a proportional valve, which is disposed within the air pipe of the pressure adjustment cylinder and connected to the pressure control unit. The pressure control unit sends increase / decrease signals to the proportional valve to control the pressure adjustment unit.

[0023] Please refer to Figure 2 The pressure regulating unit includes a pressure regulating bracket 10 and a pressure regulating cylinder 30; the rice baffle 20 is connected to the pressure regulating bracket 10, and the pressure regulating bracket 10 is rotatably connected to the rice milling machine outlet via a rotating shaft 40; the pressure regulating cylinder 30 drives the pressure regulating bracket 10 to rotate around the rotating shaft 40; the online whiteness meter 50 and appearance inspection instrument 60 are installed inside the outlet and can collect data at preset collection frequencies.

[0024] In one embodiment, the pressure control unit is a microcontroller.

[0025] In other embodiments, the material level sensor, feeding device, and main motor of the rice milling chamber in the rice milling machine are all connected to the pressure control unit. During the start-up phase, when the material level sensor senses the raw material, the pressure control unit starts the feeding device to begin operation. After the feeding begins, the pressure control unit detects the change in current and automatically sets the pressure adjustment unit according to the initial pressure setting value. It also uses the current of the main motor to provide feedback on the working pressure. Subsequently, after receiving the adjustment command from the main control unit, the pressure control unit can adjust the current output pressure by 1%-10% each time, so that the maximum adjustment range does not exceed the set maximum current and the minimum is not lower than the set no-load start threshold + 5A. The maximum adjustable range is calculated based on the number of automatic pressure adjustment devices on site. If the whiteness accuracy is still not up to standard after reaching the maximum adjustable range, it is determined that the setting value is incorrect and manual judgment and parameter modification are required.

[0026] Furthermore, the intelligent control system of this utility model also includes a host computer, and the main control unit is connected to the host computer via a communication unit. The host computer is a PC or workstation, and the communication unit includes a 4G / 5G module. This enables the real-time collected and analyzed data to be transmitted to the host computer for recording or early warning analysis.
