Palm oil is one of the important sources of vegetable oil in the world, accounting for more than 30% of the world’s total oil production. It is also known as the world’s three major vegetable oils together with soybean oil and rapeseed oil. It is used in the catering industry, food industry and oleochemical industry respectively. Has a wide range of uses. At present, China has become the world’s largest importer of palm oil. my country’s palm oil consumption is about 6 million tons per year, accounting for 20% of the total market. Southeast Asia and Africa are the main producing areas of palm oil, accounting for about 88% of the world’s total palm oil production. The oil palm tree is a crop that blooms, bears fruit and harvests all year round. The production cycle can last for 25 years. Palm oil is pressed from the fruit of the oil palm tree. Oil palm fruit contains two different oils, palm oil from the pulp and palm oil from the white palm. Therefore, the oil palm tree is a good economical plant. Workers load the picked palm fruit into the truck, ready to be transported for processing. The production process of good palm oil and palm kernel oil is very complicated, mainly through several important processes such as sterilization, refining, bleaching, and deodorization. Firstly, the palm fruit is poured into the machine, and the conveying equipment will transfer the palm fruit to the boiler, where it is boiled in high-temperature water, which can not only sterilize the fruit, but also soften the pulp. After coming out of the high-temperature boiler, it is the process of crushing and squeezing. Crude palm oil and palm cracks can be obtained from palm fruit piles. At the same time, white palm kernels will be separated during the crushing process. After crushing and removing the shell again, the remaining kernels are pressed to obtain crude palm oil. After the primary stage of extraction, crude palm oil and crude palm oil are sent to the refinery for refining. After removing free fatty acids, natural pigments and rich smell, it becomes palm salad oil. Refined palm oil is close to colorless and transparent in liquid state, close to white palm oil in solid state, slightly sweet, with pleasant violet fragrance, semi-solid at room temperature, its consistency and melting point largely Depending on the content of free fatty acids, the content of free fatty acids is lower in the international market. Low palm oil is called soft oil, and palm oil with high free fatty acid content is called hard oil.
