In the world of vegetable oil production, medium-sized screw oil presses are widely used. However, many users often encounter problems such as low oil yield and impaired oil flavor. These issues are closely related to the temperature control system of the oil press. In this article, I'll share some insights on the temperature control system of medium-sized screw oil presses to help you address these common pain points.
Temperature control plays a crucial role in vegetable oil pressing. By precisely controlling the temperature, we can improve the quality and quantity of the oil produced. For example, proper temperature control can inhibit protein denaturation, reduce oil oxidation, and enhance the clarity of the oil. According to industry data, with accurate temperature control, the oil yield can be increased by about 5 - 10%, and the quality of the oil can be significantly improved.
Let's take a look at the technical principles. In the process of oil pressing, temperature control can prevent excessive protein denaturation. When the temperature is too high, proteins in the raw materials will denature, which will affect the oil extraction process and reduce the oil yield. At the same time, it can also reduce the oxidation of oil, because oxidation will not only damage the flavor of the oil but also reduce its nutritional value. By controlling the temperature, we can keep the oil in a relatively stable state, thus improving its clarity and flavor.
The temperature control system of a medium-sized screw oil press has unique technical principles. It can effectively suppress protein denaturation, reduce oil oxidation, and improve the clarity of the oil. Different from other types of oil presses, the screw structure of the medium-sized screw oil press allows for more uniform heat transfer, which is more conducive to temperature control.
For instance, in the process of pressing, the temperature control system can adjust the temperature according to the characteristics of the screw oil press. By controlling the temperature at different stages, we can ensure that the oil extraction process is carried out smoothly. According to experiments, compared with traditional oil presses without a precise temperature control system, the oil produced by medium-sized screw oil presses with a good temperature control system has a 15 - 20% higher clarity and a more stable flavor.
The placement of sensors in the temperature control system is of great importance. The sensors should be placed in key positions to accurately measure the temperature. Here are the general principles of sensor placement:
In addition, the segmented heating mode is also an important strategy. Different raw materials have different moisture contents, and we need to adjust the temperature accordingly. For example, for raw materials with high moisture content, we can use a lower initial temperature and gradually increase the temperature during the pressing process. The following table shows the temperature adjustment suggestions for different raw material moisture contents:
| Raw Material Moisture Content | Initial Temperature | Final Temperature |
|---|---|---|
| Low (less than 10%) | 100 - 110°C | 120 - 130°C |
| Medium (10 - 20%) | 90 - 100°C | 110 - 120°C |
| High (more than 20%) | 80 - 90°C | 100 - 110°C |
To help you better understand, here is a diagram (IMAGE-URL1) showing the sensor placement and the segmented heating process.
Sometimes, the temperature control system may issue abnormal alarms. When this happens, we need to quickly diagnose and handle the problem. Here is a flow chart (IMAGE-URL2) showing the troubleshooting process for abnormal alarms:
First, check the alarm code. Different alarm codes represent different problems. For example, if the alarm code indicates a sensor failure, we need to check the sensor's connection and functionality. If it indicates a heating element problem, we need to inspect the heating element.
Based on the experience of front - line engineers, there are some common mistakes that operators may make. For example, some operators may ignore the early warning signs of the alarm system or misinterpret the alarm codes. By learning from these experiences, we can improve our emergency response ability.
In conclusion, the temperature control system of a medium - sized screw oil press is a key factor in vegetable oil pressing. By understanding its principles, properly placing sensors, and handling abnormal alarms, we can improve the oil yield and quality, reduce equipment failure rates, and enhance the market competitiveness of our products.
