In the realm of medium-sized screw oil press operations, the temperature control system stands as the linchpin for stable production. As a team with years of front - line experience, we've witnessed firsthand the challenges that temperature control anomalies can pose to the oil extraction process. Let's delve into the practical pain points and explore how to effectively handle them.
Temperature control irregularities can have a profound impact on both the oil yield and quality. When the temperature fluctuates beyond the normal range, it can lead to a significant drop in the oil extraction rate. For example, in some cases, a temperature deviation of ±5℃ can cause the oil yield to decrease by up to 10% compared to a more stable ±1℃ temperature range. Moreover, the quality of the oil can be severely compromised. Unstable temperatures can result in increased protein denaturation, which leads to a cloudy appearance of the oil and a loss of its natural flavor. This directly affects the marketability of the final product.
To address these issues, it's crucial to understand how the temperature control system works. Precise temperature control is the key to reducing protein denaturation, maintaining the stability of flavor substances, and enhancing the clarity of the oil. By keeping the temperature within an optimal range, we can prevent the breakdown of essential components in the oil, thereby preserving its nutritional value and taste. For instance, when the temperature is accurately controlled, the percentage of flavor - retaining substances can be maintained at over 90%, while in cases of poor temperature control, this figure can drop to as low as 70%.
Different raw materials have different moisture contents, which means that the pre - heating temperature range needs to be adjusted accordingly. For raw materials with high moisture content, a lower pre - heating temperature is required to avoid excessive evaporation and energy waste. Additionally, the position of the sensors is of great importance. Placing the sensors in the right locations can ensure accurate temperature measurement and timely feedback to the control system. See the following table for specific pre - heating temperature ranges based on different raw materials (see图示):
In the operation of the temperature control system, various alarm codes may appear. Each alarm code indicates a specific problem. For example, if the alarm code shows a temperature fluctuation beyond the limit, the first step is to check the sealing of the heating coil. A loose or damaged heating coil can lead to uneven heating and temperature instability. Another common alarm is related to sensor failure. In such cases, resetting the temperature control module may solve the problem. Here is a list of some typical alarm codes and their corresponding handling steps:
Regular maintenance is essential for the long - term stable operation of the temperature control system. This includes cleaning the sensors regularly to ensure accurate temperature measurement, checking the wiring connections to prevent loose contacts, and lubricating moving parts to reduce friction. By taking these preventive measures, we can extend the service life of the equipment and reduce the risk of unexpected breakdowns. For example, a well - maintained temperature control system can operate continuously for up to 5 years without major problems, while a poorly maintained one may require frequent repairs within just 2 - 3 years.
In conclusion, mastering the art of temperature control in the operation of medium - sized screw oil presses is crucial for achieving efficient, stable, and sustainable oil production.
