PLC: Flour Mills' Intelligent Upgrade Driver

In the modern field of flour production, the application of PLC (Programmable Logic Controller) technology is triggering a profound revolution, realizing a qualitative leap in the performance and production efficiency of flour mills.

Traditional flour mills have many limitations in the production process. In the grinding process, it is often difficult to adjust precisely according to the characteristics of the wheat, resulting in unstable flour quality. Different varieties, humidity and hardness of wheat require different grinding parameters, and it is difficult for manual operation to achieve timely and accurate adaptation. This easily leads to uneven flour particle size and affects product quality. In addition, in the entire production process, the connection between each 环节 depends on manual operation and experience judgment, which is not only inefficient but also prone to human errors, increasing production costs and quality risks.

The emergence of PLC has completely changed this situation. PLC is a digital operation controller with a microprocessor for automatic control. It is like the "intelligent brain" of the flour mill. Through pre-written programs and the collection and analysis of data from various sensors, it realizes precise control of the entire production process.

In the wheat grinding 环节，the PLC system is connected to humidity sensors, hardness detectors and other devices, which can quickly obtain the real-time data of the wheat. According to these data, PLC automatically adjusts the rotation speed, gap and grinding time of the grinding rollers. For example, when it detects that the wheat has a high humidity, PLC will appropriately reduce the rotation speed of the grinding rollers and increase the gap to prevent the influence of wheat adhesion on the grinding effect; for wheat with a higher hardness, it will increase the grinding force and time to ensure that the wheat can be fully ground into fine and uniform flour.

In the processes of purifying and sieving the flour, PLC also plays a crucial role. Under the control of PLC, the purifying machine can accurately adjust the air flow speed and the vibration frequency of the sieve according to the size and density of the flour particles. This enables impurities and unqualified flour particles to be effectively separated, leaving only pure and high-quality flour to enter the subsequent 环节. In the sieving stage, PLC can quickly switch the sieve pore diameter and vibration mode according to the preset flour grade standards, and accurately classify the flour into different types such as high-gluten, medium-gluten and low-gluten, meeting the diverse needs of the market for different flour qualities.

In addition to improving product quality, PLC also realizes the full-process automation of flour mill production. From the feeding of wheat, grinding, purifying, sieving to the packaging and transportation of the finished flour, each 环节 is closely coordinated and seamlessly connected under the unified coordination of PLC. Operators only need to monitor the various parameters of the production process in real time through the human-computer interaction interface in the central control room, and make remote adjustments according to the production plan and market demand. This not only greatly reduces the labor input, improves production efficiency, but also reduces the quality risks caused by human operation errors, bringing significant economic benefits and market competitiveness to flour production enterprises.

With the continuous progress of science and technology, the application of PLC technology in the field of flour mills will continue to deepen and expand. It will promote the development of the flour production industry in a more intelligent, efficient and refined direction, providing people with more high-quality and safe flour products to meet the growing market demand.
