palm oil mill screw press and refinery process
Palm fruits oil extraction processes:
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 ; easy threshing machinery;
pretreatment peel, prepared for the follow-up processing; ppalm oil mill screw press with extraction refinery and fractionation processesditioning stone, reducing the damage kernel.
3.Threshing: The purpose of threshing is the oil palm fruits be separated from the fruit bunch through strong vibration, Threshing equipment is revolving drum thresher. The oil palm fruits separated be
ejected then into the press section. Empty fruit bunch be ejected to the yard from the other side of the revolving drum, or shipped out from the plant as palm orchards slipcover to recycling use, or burning
in the locale as fertilizer for agricultural land.
4.Mashing: It is utilizing the masher which with stirrers. The main function is used for destroying the oil cells of the palm fruits, to guarantee the oil easy to press out.
5.Pressing: Oil palm fruits first carry out cooking before pressed, fruit sterilized must be re-heating for the soft pulp, and damage pulp cell structure. Then enter into continuous screw press for 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 purification
section; press cake by breaking screw conveyor into the fiber- recovery section.
6.Clarification: Machine-pressed crude oil first diluted with water washing, through settlement and filtration, the fiber material removed from the oil, and then carry out continuous settlement, the whole
divided into two parts: oil and sediment.
Palm oil/kernel oil refinery processes:
1.Preheating: Pumping crude oil into hydrate tank (oil refining tank), on one hand, quickly stirring , on the other hand, heating by steam or heat-transfer oil (in coil pipe), rise oil temperature.
2.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.
3.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.
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 palm oil mill screw press with extraction refinery and fractionation processes condition.
5.Deodorization and Dehydration:Usually ,there are some odors in the crude oil , it affects the quality of the edible oil . About our refining process , we usually use the direct steam to take odors away in the palm oil mill screw press with extraction refinery and fractionation processes condition . General speaking there is about 0.5% water in the alkali refined oil, in the deodorization pot, thetemperature is very high , it also can finish the dehydration section.
6. Filtering: This process can remove off the small amount of unsettle gum soluble impurities in the degummed oil, after oil dehydrate cooling (60 °C), filtering again, to ensure the product oil quality.
Th-en pumping the final oil into the oil tank.
1. Product customization:
Customers no need to buy all the production lines. They can accord to their mateirals, capacity and final product to chose the machines.
2.Installation,debugging and training:
After getting order, we will help the final user to design the factory layout. And we will provide technicians to help the final user to install and debug the whole line. After the machines running well, our technicians will train the workers how to operate the machines and how to maintain the general problems.
1 year. It is calculated from the day of the machines running successful. During this period, if there is any problem caused by machines quality problem, we will change free. If caused by wrong operation, we will change the machines parts at cost prices. As the suppliers we will provide maintenance support in machines whole service life.
palm oil mill screw press with extraction, refinery and fractionation processes
adopts special steam distillation method used for the extraction of essential oil from various plants, like lavender, peppermint, and rose. Featured with compact structure, easy operation and energy saving, palm oil mill screw press with extraction refinery and fractionation processes is popular in small-scale production of cosmetics, food, Chinese medicine, etc.
A lot of can be employed in the whole oil extraction plant. Our oil extraction machine is fabricated with the most up-to-date extraction technology and premium quality raw materials, our palm oil mill screw press with extraction refinery and fractionation processes are be applied on your extraction of oils. This ensure higher production without any breakdown. The is proper for a number of seeds and nuts like Sesame Seeds, Sunflower, Palm Kernel,Cocoa,Coconut,Castor,Cotton Seed,Almond, Apricot (Germ) etc.
palm oil mill screw press with extraction refinery and fractionation processes Conventional coconut oil processors use hexane as a solvent to extract up to 10% more oil than produced with just rotary mills and expellers. They then refine the oil to remove certain free fatty acids to reduce susceptibility to rancidification. Other processes to increase shelf life include using copra with a moisture content below 6%, keeping the moisture content of the oil below 0.2%, heating the oil to 130-150 °C (266-302 °F) and adding salt or citric acid.
