What are the process of and what machinery is used for crude palm oil extraction?

The steps involved in crude palm oil extraction include raw material reception, sterilization, threshing, digtesing, pressing, filtration process and vacuum dryer system and storage. Here are the specific process of and machinery used for crude palm oil extraction.

1. Palm fruit reception: the first is raw material reception in crude palm oil extraction. Fresh palm bunches collected from plantations need to be treated within 48 hours to prevent FFA from increasing and affecting the quality of the oil later on. They are transported by truck or other means to the factory, weighed and put into the unloading table for other processes.

2. Sterilizer: the purpose of sterilization section in crude palm oil extraction is to soften and sterilize the fruit so that it is easy to fall off and press.

3. Palm fruit thresher: thresher is mainly for separating palm fruit from palm fruit bunches in the process of palm oil processing. According to processing capacity per hour, Glory Oiltech have simple type thresher with capacity 500kg/h and drum type from capacity 1-2t/h to 15t/h. After threshing, palm fruit and empty palm fruit bunches will be separated effectively.

4. Digester: digester is for crushing palm pulp and breaking the cell of pulp in palm oil processing. The destruction of the fiber structure facilitates subsequent pressing and helps to improve the final oil yield. There are horizontal and vertical digesting tanks which can be chosen based on their factory design and area or other actual needs.

5. Presser: the pressing section in crude palm oil extraction is an important step. The oil press is used to press the palm fruit. The fruit and nut are separated from the front part of the oil press and extruded to get crude palm oil and palm nut. The oil press produced by Glory Oiltech has high oil yield and can maintain continuous production.

6. Oil clarification station: for the filtration stage in crude palm oil extraction, CPO is subjected to a series of filtration processes such as vibrating screen, oil clarification tank and plate filter, layer by layer filtration to ensure the quality of oil. If the water in the oil is not removed, it is difficult to keep it for a long time, so a vacuum drying system is needed. Then use a vacuum drying system to evaporate excess water for easier storage. Finally, the clean crude oil is introduced into the crude oil tank for temporary storage.

7. Oil storage tank: the final step is the storage and crude palm oil transportation in crude palm oil extraction. The crude oil is transported by truck or other means and stored.
