Description

Technical Field

[0001] The invention relates to the technical field of rice processing, in particular to a high-efficiency screening system for rice processing. Background Art

[0002] Screening is a key step in traditional rice processing, primarily removing impurities, grading rice grains, and improving rice purity and quality. Existing screening systems often suffer from low screening efficiency, inaccurate grading, and incomplete impurity removal, making them unable to meet the high-efficiency and high-precision screening requirements of modern rice processing plants. Therefore, a new, efficient screening system is urgently needed to improve production efficiency and rice quality. Summary of the Invention

[0003] In view of the above situation, in order to overcome the current technical defects, the purpose of the present invention is to provide an efficient screening system that can effectively remove impurities in rice, accurately grade rice, and improve the efficiency and quality of rice processing. Through reasonable design, the present invention integrates multiple advanced screening technologies, solves the shortcomings of the existing technology, and has a high market application prospect.

[0004] The technical solution adopted by the present invention is as follows: The high-efficiency screening system for rice processing proposed in this solution includes a vibration screening control system, a multi-layer screen system, an airflow sorting system, a magnetic separation equipment control system and an automatic control system. The vibration screening control system is used to control the vibration screening equipment to perform preliminary screening on the rice to remove larger impurities and rice grains that do not meet the requirements. The multi-layer screen system is used to control the multi-layer screen machine to perform fine classification according to the size of the rice grains. The airflow sorting system is used to control the airflow to separate light impurities, dust and small particles from the rice grains. The magnetic separation equipment control system is used to control the magnetic separation equipment to remove metal impurities in the rice.

[0006] Furthermore, the vibration screening equipment is divided into a linear vibration screen and a circular vibration screen. The above equipment can separate rice from larger impurities under the action of vibration, ensuring the efficiency of rice grains passing through the screen.

[0007] Furthermore, the multi-layer screen system includes multiple screen layers, and the screen aperture of each layer gradually becomes smaller, so that the rice grains are graded according to size and screened step by step to achieve a fine grading effect.

[0008] Furthermore, the airflow sorting system separates lighter impurities such as dust and floating objects through an adjustable airflow device, thereby ensuring the purity of the rice.

[0009] Furthermore, the magnetic separation equipment adopts a strong magnetic separation device to remove metal impurities in rice and ensure food safety.

[0010] Furthermore, the automated control system is equipped with intelligent sensors for real-time monitoring of data during the screening process, including the vibration frequency, amplitude frequency, screen speed and equipment pressure of the screen, and automatically adjusts the operating status of the equipment through the control system to adapt to different processing requirements.

[0011] The beneficial effects achieved by the present invention using the above structure are as follows: The high-efficiency screening system for rice processing of the present invention has the following advantages:

[0012] 1. Through multiple screening technologies such as vibration screening, air flow separation and magnetic separation, impurities in rice can be effectively removed, screening efficiency can be improved, and the purity of rice can be ensured.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] like Figure 1 and Figure 2 As shown, the technical solution adopted by the present invention is as follows: The high-efficiency screening system for rice processing proposed in this solution includes:

[0023] Vibration screening control system: The vibration screening control system is used to control the vibration screening equipment to perform preliminary screening on rice. Through vibration, the rice is separated from larger impurities and smaller rice grains are ensured to pass through the screen. The vibration screening equipment is composed of a linear vibrating screen and a circular vibrating screen to meet the screening requirements of different specifications. The linear vibrating screen is used to process larger impurities in rice, and the circular vibrating screen is used for fine-grade screening to ensure screening accuracy and efficiency.

[0024] Multi-layer screening system: The multi-layer screening system controls a screening machine composed of multiple screen layers. The aperture of each layer of the screening machine gradually becomes smaller, and the rice is screened step by step according to size to ensure fine grading of rice grains. The design of each screen layer can be adjusted according to the size difference of rice grains to improve the accuracy and efficiency of grading.

[0025] Airflow sorting system: The airflow sorting system uses an adjustable airflow device to separate light impurities such as dust and light objects through airflow to ensure the purity of rice. The wind force of the airflow sorting system can be adjusted according to the characteristics of different impurities and rice grains to achieve the best separation effect, thereby ensuring the cleanliness of rice and improving food safety and quality.

[0026] Magnetic separation equipment control system: The magnetic separation equipment control system is used to control the magnetic separation equipment to remove metal impurities in rice. The magnetic separation equipment uses a high-efficiency magnetic source to quickly identify and separate metal impurities, prevent metal contamination of rice, and ensure food safety. The magnetic separation equipment can work in conjunction with screening equipment to achieve multiple filtrations to ensure that metal impurities are completely removed.

[0027] Automated Control System: This system monitors and adjusts the operating parameters of all equipment during the screening process. Intelligent sensors monitor real-time data from the screening process, including key parameters such as the vibrating screen's frequency, amplitude, mesh speed, and equipment pressure. Based on these data changes, the system automatically adjusts equipment to meet varying processing requirements. The automated control system also includes a cleaning and maintenance subsystem, which monitors equipment through sensors and automatically cleans the equipment to prevent mesh surface clogging, improve screening efficiency, and reduce maintenance and downtime.

[0028] During specific use, a linear vibrating screen is used to coarsely screen the rice to remove larger impurities. The rice grains that pass through are then fed into a circular vibrating screen for further screening to ensure uniform rice grain size and achieve a relatively fine screening effect. A multi-layer screen system dynamically adjusts each layer of screen according to the size and quality requirements of the rice grains. After the rice grains are graded by the screens, an airflow sorting system removes light objects such as dust and light impurities. During this process, the airflow speed and pressure can be adjusted in real time by the control system according to the characteristics of the rice to ensure that the purity of the rice grains meets food safety standards. After screening, the magnetic separation equipment is controlled by the magnetic separation equipment control system. The strong magnetic force efficiently absorbs and removes metal impurities in the rice, preventing metal contamination from affecting the rice quality. This process uses a closed-loop control system to ensure that all metal impurities are removed. The automated control system monitors various data during the screening process, such as the vibration frequency of the screen and the equipment pressure, through multiple sensors, and automatically adjusts the equipment's operating status. The cleaning and maintenance subsystem regularly checks the equipment's operating status and monitors the equipment's condition through sensors, automatically cleaning and keeping the screen unblocked to ensure efficient operation.
