How do I extract palm oil by using a palm oil expeller?

To extract palm oil by using a palm oil expeller from fresh palm fruit, you need to follow a series of steps that include preparing the fruit, feeding it into the palm oil expeller, and processing it to extract palm oil. Here is a step-by-step guide of extracting palm oil by using a palm oil expeller:

Step1. Preparating Palm Fruit

(1) Harvesting: The palm fruit is harvested from the oil palm tree. Ripe, fresh fruit bunches are essential for good oil yield.

(2) Sterilizating: Freshly harvested fruit is typically sterilized by steaming. This helps soften the fruit and makes it easier to separate from the bunch, while also preventing the degradation of oil quality.

(3) Threshing: After sterilizating, the individual fruits are separated from the bunches using a palm fruit thresher. This is done manually or mechanically. It is worth noting that the separation rate of the palm fruit thresher produced by Henan Glory can reach more than 95%.

(4) Digesting: The separated palm fruit is then fed into a digester, where it is digested. Then the digested fruit (mashed pulp) is now ready to enter the palm oil expeller for pressing.

Step2. Feeding the Palm Fruit into the Palm Oil Expeller

(1) Preparing the Palm Oil Expeller: Make sure the palm oil expeller is in good working condition and lubricated as per the manufacturer's instructions.

(2) Loading the Digested Palm Fruit: The digested palm fruit is fed into the palm oil expeller hopper, which is the entry point to the screw palm oil expeller.

Step3. Operating the Palm Oil Expeller

(1) Turning On the Palm Oil Expeller: Starting up the palm oil expeller. The palm oil expeller works by using a rotating screw that applies pressure on the pulp inside a cylindrical casing (press cage).

(2) Implementing Pressing Action: As the pulp moves along the palm oil expeller screw, mechanical pressure is applied to release the palm oil. The palm oil flows through a series of screens and is collected in a container. The liquid palm oil that is collected through the oil outlet.

(3) Collecting Palm Oil: The crude palm oil flows through the collection system. This palm oil may contain water, impurities and residual solids, which will need to be processed further (clarified).

Step4. Clarifying the Crude Palm Oil

(1) Settling: Allow the extracted palm oil to settle for a while, so that heavier impurities, like solid particles and water, separate and settle at the bottom.

(2) Centrifugation: To further purify the palm oil, use a centrifuge to separate additional impurities from the crude palm oil. This is often done at the palm oil mill to ensure a higher quality of oil.

(3) Filtration: The clarified palm oil can be passed through a fine filter to remove any remaining particles.

Key Points to Remember When Extracting Palm Oil by Using a Palm Oil Expeller:

(1) Monitoring the Palm Oil Expeller: Regularly check the palm oil expeller's performance. If the palm oil extraction seems low, adjust the settings or check for blockages.

(2) Pay Attention to the Quality of Raw Materials: Ensure that the fruit is fully ripe, as immature or overripe fruit can result in lower oil yields and poor-quality oil.

(3) Maintaining the Palm Oil Expeller: Regularly clean the palm expeller and ensure it is well-lubricated to prevent wear and ensure consistent operation.
