Working principle of palm oil press

The palm oil press is a screw press designed and developed based on the physical and chemical properties of palm kernel raw materials. It achieves multiple squeezing of raw materials through multiple processes such as pre-pressing, extrusion, forming, cake breaking, relaxation, and re-extrusion, effectively destroying the cell structure of the raw materials and reducing the content of residual oil in the pressed cake. At the same time, the surfaces of consumable parts such as press screws, press bars, and bushings are treated with special processes and covered with wear-resistant materials, which greatly increases their service life, reduces the frequency of replacement parts, and reduces the labor intensity of workers.

Palm oil press has the following features:

The pre-pressed cake has good forming effect.

The structure design is reasonable and the body has good rigidity.

The transmission system is stable and reliable.

Consumable parts such as snails and strips are treated with special technology to have a long service life.

The pressing process of palm oil generally adopts the secondary extraction and pressing method. First, palm skin oil is extracted, and then the palm kernels are screened out and pressed twice to obtain palm kernel oil. Due to the special structure of palm fruit, there are some significant differences in the oil extraction process when compared with other crops when using a screw oil press.

The oil extraction process of palm nut is as follows:

Receive palm fruit spikes.

Perform threshing to separate the pulp from the palm kernels.

The palm kernels are ground into small particles and heated.

Use an oil press to extract oil from palm kernels.

The pressed oil is clarified and filtered to obtain pure palm fruit oil.

The remaining pulp can be dried and then pressed to fully extract the oil.

By using a palm oil press, you can achieve efficient processing of palm fruits and improve oil extraction efficiency. The equipment has a stable and reliable transmission system and durable wearing parts, which extends its service life.
