High-tech palm oil refining machinary
Palm fruit, palm kernel, coconut, cashew, avocado, tiger nut, peanuts, rapeseeds, soybeans, castor oil plant, sesame seeds, benne seeds, sunflower seeds, cotton seeds, tea seeds, Tung seeds and etc.
1. Introduction of palm oil mill
1)Palm oil mill have main five parts: Reception Station,Sterilizer,Threshing,Press,Clarifition and Kernel Recover.
2)We use the Fresh Fruit Bunch, because the palm fruit rancidity is very fast, if the rancidity will be influence the palm crude oil acid value,if the acid value is very high, the refining efficience will drop.
3)Generally speaking, the palm oil mill be mainly located in Nigeria,Malaysia,Indonesia etc..
2. Main parts of palm oil mill
1) Reception Station: used for loading palm fruit brunch from plantation,transport to sterilizer. Reception station adopt steel structure and concrete structure. Save equipment cost and construction cost.
Have hydraulic control system, hydraulic door open/off automatic achieve continuous operation. Reduce operator, operate more easily and improve work efficiency.
2)Sterilizing Tank: The sterilizing tank uses direct steam to process, which can reduce activity of the enLDme,prevent the rancidity, ensure the good quality of the crude oil. At the same time, it is good for the trashing process.
3)Threshing station: Fresh palm fruits separate from bunches by thresher rotary drum rotating. Palm fruits are conveyed to digesting tank by elevator.Empty bunches are coveyed out of factory by scraper conveyor. Thresher shaft uses once forging technology. The equipment is stronger and has longer life. At the same time, our company developes non-shaft thresher drived by chain. In this way, it reduces power loss and saves production cost.
4)Digestor: Inside of sterilizer, there are some baffle and stirring arm, under the drive of top motor.Baffles break off the palm fruit, then heat palm fruit pulp. So that can press oil easily. Get higher oil yield. Meanwhile there is directly steam inlet digester, to adjust material moisture.
5)Pressing Machine:The palm fruit oil yield increases by adjusting material moisture and temperature in digesting tank. Digesting tank uses liquid level control, so material can distribute automatically and equipment runs fully automatically.Pressing machine uses hydraulic control system to adjust spacing between pressing bolts. So it can be suitable for variouss palm fruit species and guarantee the oil yield.
6) Kernel Recovery Station:Using air duct system to separate palm shell and kernel. Meanwhile,using special mud bath equipment to separate palm kernel and shell according to their different density. So it has high separation rate. There are some fiber cover the palm nut, in order to get palm kernel, should remove the fiber,palm shell.Fiber and shell is very good resource for boiler fuel.
7)Clarification Station: Oil purifying system, using latest technology, on the premise that guarantee oil quality, we try our best to reduce machine inverstment and oil loss. In actul production, it has been verified that using new technology can reduce oil loss below 1.3%.
8)Palm oil refinery technology:Oil refining is based on the difference of oil and the impurities in the physical and chemical properities, separate the grease and impurity by some technical ways, in order to improve the oil edible, storage stability and safety process. Oil refing process is divided into chemical refining and physical refining.
9)Palm oil fractionation technology is a new oil processing technology.Using palm oil fractionation technology can get 8℃,10℃,14℃,18℃,24℃,33℃,44℃,55℃ etc, different melting point's palm oil product. At the same time, it can also be used to do cottonseed oil, fish oil ,pork oil and other animal oils. This prominently improves the added value of the oil products, increase the economic benefit of enterprise.
3. Advantages of palm oil mill
1) High oil yield, obvious economic benefit.
2) Less residual oil rate in the dry meal.
3) Improving the quality of the meal.
4) Low processing cost, high labor productivity.
The oil quality outcome standard:
1. Grade one for salad oil
2. Grade two for high quality cooking oil
3. Mixture and volatile less than 0.25%.
4. Impurity less than 0.2% .
5. AV (mgKOH/g) less than 7.
6. FFA less than 3.5%.
