In the tropical regions of Southeast Asia and Africa, palm oil processing is a significant economic activity. However, small - scale palm oil processors often encounter various challenges in the primary processing stage. This article aims to introduce the cold - hot double pressing technology developed by Penguin Group, which offers a solution to these common problems.
Tropical areas are characterized by high temperature and high humidity, which pose unique challenges to palm oil processing. High - moisture palm fruits are common in these regions, and traditional single - pressing methods often struggle to process them efficiently. The high temperature can also accelerate the oxidation of palm oil, reducing its nutritional value and stability. Moreover, the unstable power supply with multiple voltage levels in these areas may lead to equipment malfunctions and inefficiencies.
Let's first look at the traditional single - pressing method. In this approach, the palm fruits are usually pressed at a single temperature. This method has limitations in terms of oil quality, oil - extraction efficiency, and equipment adaptability. For example, the oil extracted by traditional single pressing may have a lower natural nutrient content because the high - temperature pressing process can destroy some of the heat - sensitive nutrients. The oil - extraction rate is also relatively low, especially for high - moisture palm fruits.
In contrast, the cold - hot double pressing technology combines the advantages of both cold and hot pressing. Cold pressing is carried out at a relatively low temperature, which can effectively retain the natural nutrients in the palm oil, such as vitamin E and carotenoids. Hot pressing, on the other hand, can break down the oil - containing cells more thoroughly, increasing the oil - extraction rate. According to our research data, the oil - extraction rate of the cold - hot double - pressing method can be up to 10% higher than that of the traditional single - pressing method. In addition, the combination of cold and hot pressing can enhance the stability of the palm oil, reducing the oxidation rate and extending its shelf life.
| Pressing Method | Oil Nutritional Value | Oil - Extraction Rate | Oil Stability |
|---|---|---|---|
| Traditional Single Pressing | Relatively low | 70 - 75% | Relatively poor |
| Cold - Hot Double Pressing | High | 80 - 85% | Good |
In tropical regions, the power supply often has multiple voltage levels. The equipment designed by Penguin Group can adapt to different voltage requirements, which is crucial for small - scale palm oil processors. Incorrect equipment selection due to voltage mismatch can lead to serious efficiency losses and even equipment breakdowns. With the multi - voltage adaptation design, processors can operate the equipment stably without worrying about power - supply issues.
Let's take a small - scale palm oil processing plant in Africa as an example. Before using the cold - hot double - pressing technology, they used a traditional single - pressing method. The oil - extraction rate was only about 72%, and the oil quality was not satisfactory. After switching to the cold - hot double - pressing equipment provided by Penguin Group, the oil - extraction rate increased to 83%. The oil also had a higher content of natural nutrients and better stability, which allowed them to sell the oil at a better price in the market. Moreover, the multi - voltage adaptation design of the equipment ensured stable operation even in the face of unstable power supply.
Understanding the cold - hot double - pressing technology and its application value can help palm oil processors in tropical regions optimize their production efficiency, improve oil quality, and ultimately achieve sustainable operations and stable profits.
