10-100t/d Small Crude Palm Kernel Oil Refinery Milling Machine Palm Oil Production Process Line

This palm oil plant is fully automatic. It requires less workers and improves the working efficiency. 

(1)Raw materials receiving: Fresh palm fruit bunch will be loaded on a slope. Under the slope, there are some cages to receive the palm fruits.
(2)Sterilizing: fresh palm fruits bunch are airtight sterilized in sterilizer. The purpose to prevent enzymes broken down, avoiding FFA content in oil further increase.
(3)Threshing: The purpose of threshing is the oil palm fruits separated from the fruit bunch through strong 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: This is the most important section of hydrate de-gumming, manage the adding water (there is a little P-acid in the water) amount, temperature and add water speed, usually water adding amount is about 3 times of phospholipid content, that is 3-10% oil weight, water temp needs to be higher than oil temp.

(2)Deacidification:This part adopt alkali refining method, that is use alkalis like (NaOH) to neutral the free fatty acid in oil, during this process it will produce soapstock , then separated from the oil by setting several hours. NAOH solution, not only neutral free fatty acid, also can act with other matters like protein, mucus, phospholipid, pigment. After settling, release the soapstock from the tank bottom. Adding hot water to rinse, remove off the leftover lye , soap and some unhydrated phospholipid in the oil. Finally pumping out soapstock from the tank bottom

(3)Decolorization: In normal situation , there is pigment in the crude oil , we need to using the active clay to absorb the pigment away , after 20 mins , we use the vibrating filter to filter the waste clay away . If you want to get light color oil , you need to add more active clay . That is mean , the customer can accord to his requirement to control the oil color. This process is carried out under the vacuum condition.

Palm oil processing plant Sterilizing Station

Fresh palm fruit string into the kill fermenter, sealed fermentation. Fermentative purpose in order to prevent enzyme decomposition, so as to avoid further increase in the content of free fatty acids in oil; facilitate mechanical threshing; pretreatment of peel, preparation for subsequent processing; Preconditioning kernel, reducing kernel damage.

Palm oil processing plant Pressing System

Oil palm before pressing to be cooking, will kill leavening,The reheated fruit softens the flesh and destroys the flesh Cell structure. Cook into the continuous screw press squeeze.After the oil palm oil is squeezed into two parts: oil, water, A mixture of solid impurities and press cake (fiber and core).Oil, water, a mixture of solid impurities through the hair tank into the oil Chemical sector; pressed cake through the broken screwdriver into the fiber recovery section

Palm oil processing plant Clarification System

Machine pressed oil diluted with water after sedimentation, filtration, fiber material removed from the oil, and then for continuous settlement, divided into two parts: oil and sediment. The oil is separated by centrifugation and is pumped into a storage tank for storage under vacuum. After the oil sediment is filtered and the oil is separated, the oil is subjected to secondary sedimentation, the oil-oil mixture is clarified and separated, the oil sketched is subjected to secondary sedimentation, Into the sewage treatment tank.

Palm oil processing plant Water System

Only the after treated supply water can meet the sanitary requirement. Especially, the furnace supply water should be softened first, After anion and cation exchange resin treatment, meet the requirements of the boiler water, then be treated by deaerator for removing oxygen. At last, pump it into temporary tank for storage.
