Are you still relying on manual control for your edible oil production line? Compared to the PLC intelligent system, manual control suffers from high energy consumption, poor consistency, and frequent breakdowns. It's time for an upgrade! In this article, we'll delve into how an industrial-grade PLC system can achieve precise control throughout the entire edible oil production process, from raw material processing, pressing, refining to filling, reducing unplanned downtime and enhancing Overall Equipment Effectiveness (OEE).
PLC control systems bring significant advantages over manual control. One of the key aspects is the precise temperature closed-loop control. In the pressing process, maintaining the right temperature is crucial for the oil extraction rate. With manual control, it's difficult to keep the temperature stable, which may lead to a lower oil yield. However, a PLC system can adjust the temperature accurately, increasing the oil extraction rate by up to 10% according to industry data.
Another important function is the pressure linkage monitoring. In the refining stage, proper pressure is essential for the quality of the edible oil. PLC systems can continuously monitor and adjust the pressure, ensuring the quality consistency of the final product. A study shows that the use of PLC in pressure control can reduce the quality deviation by 15% compared to manual control.
In the raw material processing phase, accurate temperature control is vital. For example, in the pre - heating of oilseeds, a PLC system can maintain a stable temperature within a narrow range. This not only improves the oil extraction efficiency but also reduces the energy consumption. In a real - world scenario, a medium - sized edible oil manufacturer reduced its energy consumption by 20% after implementing a PLC - based temperature control system.
During the refining process, pressure affects the removal of impurities and the quality of the oil. The PLC system can monitor the pressure at different points and adjust it in real - time. This ensures that the oil meets the quality standards consistently. In a large - scale edible oil plant, after adopting the PLC pressure monitoring system, the percentage of non - compliant products decreased from 5% to 1%.
With the remote monitoring and alarm mechanism, operators can keep an eye on the production line from anywhere. If there is an abnormal situation, such as a sudden drop in temperature or a rise in pressure, the system will send an alarm immediately. This allows for quick response and reduces the risk of major breakdowns. For instance, a small - scale edible oil factory avoided a potential production halt by receiving an early alarm from the PLC system, saving them a significant amount of money in production losses.
Case 1: A B2B edible oil manufacturer noticed a decrease in the oil extraction rate and an increase in energy consumption. After analyzing the data from the PLC system, they found that the sensor in the pre - heating tank was giving false readings. By replacing the sensor, the oil extraction rate returned to normal, and the energy consumption decreased by 15%.
Case 2: Another company experienced inconsistent product quality. The PLC system detected a motor synchronization deviation in the filling process. After adjusting the motor parameters, the quality consistency improved significantly, and the rejection rate dropped by 20%.
To keep the PLC system running smoothly, regular maintenance is necessary. Here are some practical maintenance suggestions:
We also provide a quick diagnostic checklist. If you encounter problems such as sensor false alarms or motor synchronization issues, you can refer to this checklist to quickly identify and solve the problems.
As you can see, the PLC control system offers numerous benefits for edible oil production lines, including higher oil extraction rates, better quality consistency, and lower energy consumption. It's no wonder that global B2B edible oil manufacturers are upgrading their production lines with PLC automation.
