(1)Raw supplies receiving: Recent palm fruit bunch can be loaded on a slope. Below the slope, there are some cages to obtain the palm fruits.
(2)Sterilizing: recent palm fruits bunch are airtight sterilized in sterilizer. The aim to prevent enzymes damaged down, avoiding FFA content material in oil further improve.
(3)Threshing: The aim of threshing is the oil palm fruits be separated from the fruit bunch by way of robust vibration.
(4)Pressing: Oil palm fruit pressed is divided into two parts: oil, water, solid impurities mixture and the press cake (fiber and nuclear). Oil, water, solid impurities mixture by the crude oil gutter inflow to oil purificationsection; press cake by breaking screw conveyor into the fiber- recovery section.
(1)Degumming: That is a very powerful section of hydrate de-gumming, handle the adding water (there may be slightly P-acid in the water) quantity, temperature and add water speed, usually water adding amount is about 3 occasions of phospholipid content, that’s 3-10% oil weight, water temp must be greater than oil temp.
(2)Deacidification:This half adopt alkali refining methodology, that is use alkalis like (NaOH) to impartial the free fatty acid in oil, during this process it would produce soapstock , then separated from the oil by setting a number of hours. NAOH answer, not only impartial free fatty acid, also can act with different issues like protein, mucus, phospholipid, pigment. After settling, release the soapstock from the tank bottom. Including sizzling water to rinse, remove off the leftover lye , cleaning soap and some unhydrated phospholipid in the oil. Lastly pumping out soapstock from the tank bottom
(3)Decolorization: In regular state of affairs , there may be pigment within the crude oil , we need to utilizing the energetic clay to absorb the pigment away , after 20 mins , we use the vibrating filter to filter the waste clay away . If you wish to get light color oil , you want to add more energetic clay . That is mean , the customer can accord to his requirement to regulate the oil colour. This course of is carried out beneath the vacuum condition.
