To invest in building a palm oil processing plant, investors must fully understand the palm oil processing process, facilitate the equipment of the palm oil plant, and then produce edible oil that meets market demand. There are many palm oil plants served by Henan Huatai Cereals and Oils Machinery Co., Ltd. Here is a brief introduction to the transformation of palm fruit into palm oil. It needs to go through a series of mechanized procedures, including sterilization, threshing, digesting, pressing, deacidification, decolorization, deodorization, fractionation, drying, packaging and other processes.
Sterilization is an important step in palm oil processing. Sterilization is a heat treatment process that softens and loosens the fruit and falls off the fruit stalk. At the same time, it is better to reduce the activity of lipase to avoid the production of a large amount of free fatty acids, thereby ensuring the quality of the finished oil.
The threshed palm fruit needs to be cleaned, screened, crushed and other pre-treatment processes to fully destroy the internal structure of the oil, so as to achieve a state that is convenient for oil extraction, and then be pressed or extracted. Palm fruit has a high oil content, and the oil yield of mechanical pressing is in the range of 75% to 90%. In this process, the palm oil mill can use the palm oil screw press to continuously process and obtain a good oil yield.
For most oils, the pressed cake will be extracted during processing to reduce the oil content in the oil cake. In palm oil production, the oil cake is rarely extracted, because the palm fruit is pressed to obtain a mixture of palm kernels and fibers, and there is very little residual oil in the cake. It is not necessary to extract the pressed cake to increase the oil yield, and the palm kernel can also be further processed to extract palm kernel oil, so mechanical pressing is basically sufficient for processing palm oil.
The liquid obtained by pressing is a mixture of water, oil, dry matter, and fruit residues. It needs to be separated from other substances through subsequent operations such as centrifugation and vacuum drying to obtain crude palm oil. Crude palm oil contains colloid-soluble impurities such as phospholipids, proteins, and viscous substances, as well as impurities such as free fatty acids and pigments. It needs to be processed by palm oil refining machine to separate them to obtain healthy, nutritious and safe edible oil finished oil.
Palm oil refining can be divided into physical refining and chemical refining. The main difference between the two processes lies in the separation method of free fatty acids. The deacidification process of physical refining is carried out simultaneously with the deodorization process, while the deacidification process of chemical refining is usually placed after hydration degumming. The physical refining deacidification method uses the characteristics of free fatty acids and odor molecules that are highly volatile under high temperature and high pressure conditions to separate these impurities by passing steam into the crude oil.
The choice of refining process by the palm oil mill should be determined according to the actual situation. In this process, the investment and construction of palm oil mills cannot do without the application of mechanical equipment. It is recommended that the oil mill cooperate with Huatai Oil Machinery, which is experienced and has served thousands of oil mills. The manufacturer has mature technical skills and conscientious and responsible staff. It can provide reasonable mechanical equipment for customers according to their actual situation, provide practical solutions for oil mills, and help the production of oil mills.
