Palm oil can be directly squeezed and extracted from the palm fruit on the oil palm tree. This unrefined palm oil is called crude palm oil, which contains more impurities and acid value. Crude palm oil can be used directly for certain industrial purposes, but if it is used as edible oil, it needs to be refined to improve its quality and safety. Palm oil refiner is an important part of the palm oil production line. Through a series of complex processes such as degumming, deacidification, decolorization, deodorization, dewaxing, etc., impurities and undesirable components in palm oil are removed to improve the quality and stability of palm oil. Refined palm oil is widely used in the catering industry, food industry and oil and fat chemical industry.
The main process flow of palm oil refining includes the following steps:
1. Degumming: remove phospholipids, mucus, resin, protein, sugar, trace metals, etc. from crude oil, generally using hydration and acid refining methods.
2. Deacidification: Use food-grade alkali neutralization method to remove free fatty acids, acid pigments, sulfides, insoluble impurities and trace metals in the oil.
3. Washing: Wash away the soap and water-soluble impurities remaining in the oil during the deacidification process.
4. Dehydration: Use heating and vacuum drying to remove moisture from refined oil.
5. Decolorization: Use adsorbents such as white clay, aluminum silicate, and activated carbon to remove various pigments, colloids, oxides, etc. in the oil.
6. Deodorization: Use the vacuum gas extraction principle to remove low-molecular odor substances, free fatty acids, monoglycerides, glycolipids, sulfides, thermal decomposition products of pigments, etc. in the oil.
7. Dewaxing or degreasing: Mainly use freezing, crystallization or winterization crystallization to fractionate and remove wax fats in the oil.
The characteristics of palm oil refiners are mainly reflected in technological innovation, degree of automation, energy consumption control, and improvement of finished oil quality. The following are some key features of palm oil refiners:
1. Efficient impurity removal
Fine degumming: It can efficiently remove impurities such as colloids, phospholipids, proteins, etc. in crude palm oil, and improve the stability and shelf life of the oil.
Low acid value: Effectively remove free fatty acids through physical or chemical refining methods to ensure that the acid value of refined oil meets the standard.
Thorough decolorization: Through decolorization processes such as activated clay and activated carbon, reduce pigments and residual impurities in the oil, and improve the color and transparency of the oil.
2. Automatic control
Automatic operation: The equipment usually integrates a PLC automatic control system, which can accurately control parameters such as temperature, pressure, time, etc., improve production efficiency, and reduce human operation errors.
Full process monitoring: The entire refining process can be monitored in real time, including key parameters such as temperature, pressure, and flow rate, to ensure the precise execution of each refining stage.
Automatic slag discharge: Some advanced equipment has an automatic slag discharge function, which can reduce the workload of operators and improve production efficiency.
3. Energy saving and environmental protection
Energy recovery: The equipment often has a heat recovery function, which reduces energy consumption and production costs by recovering waste heat.
Environmental protection treatment: Some equipment has a wastewater treatment system that can effectively treat wastewater generated during the production process and reduce the impact on the environment. Odors and exhaust gases can also be filtered and discharged through a special treatment system to meet environmental protection standards.
4. Versatility
Multiple refining methods: Supports multiple processes of physical refining and chemical refining, and adapts to the processing needs of different types of palm oil, including crude palm oil, refined palm oil and other edible oils.
Strong compatibility: Refiners are usually able to process a variety of vegetable oils, such as soybean oil, rapeseed oil, etc., which are suitable for the diversified production needs of oil mills.
5. Stable and reliable performance
High durability: The equipment materials are mostly made of high-quality stainless steel, which has strong corrosion resistance, adapts to the complex working conditions of oil refining, and has a long service life.
Continuous and stable operation: The equipment can realize continuous refining process, reduce equipment downtime maintenance time, and improve the operating efficiency of the production line.
High-precision control: The control of temperature, pressure, time and other parameters during the refining process is accurate, ensuring the stability and consistency of each step and improving the quality of the final product.
6. High quality of finished oil
Improved taste: The deodorization process removes odors and volatile substances in the oil, improves the taste of the oil, and makes it more suitable for direct consumption.
Excellent color: The efficient decolorization function ensures that the oil product has a bright color and meets the market demand for high-quality palm oil.
Nutrient retention: Modern physical refining equipment can retain more nutrients, such as vitamin E, during the refining process, improving the nutritional value of the oil.
7. Low operating cost
Efficient energy saving: The automated control and heat recovery system reduce energy consumption and reduce the operating costs of the factory.
Easy maintenance: The equipment is reasonably designed, easy to operate and maintain, reducing downtime and maintenance costs.
In summary, the palm oil refiner can meet the modern oil processing industry’s demand for high-quality and efficient refining processes with its advantages of high efficiency, energy saving, and high degree of automation.
