crude palm oil refining machine
Equipments which directly related to the palm fruit oil process (from fresh fruit to
final products)are divided into six systems as follows:
Press Process
1.Fruit reception system
1.1 Use truck to transport the ripe and fresh palm fruits from fruit ranch, weigh up
them by platform scale and record, and then pour them into the discharging table.
1.2 Start control valve to open the discharging table, then fruit drop in the fruit
basket car freely.
1.3 Drag the fruit basket car which loaded with fresh palm fruits to the downward
of the bridge crane by power cable tray and cable tray, then use bridge crane to
sling the fruit basket car to the track lead to sterilizer sterilizing tank.
2. Sterilizer system
2.1 After drag the fruit basket car into the sterilizer sterilizing tank, close the sterilizer
sterilizing tank and open the vent valve below it. Then inlet saturated vapor, close the
vent valve after the cold air in the tank was excluded generally, and enter into the
period of steaming and sterilizing.
2.2 Close the inlet valve after the sterilizing process. Drain out the water and vapor in
tank, then you can open the door of the sterilizer sterilizing tank.
2.3 Drag the cooked fruit basket car to the downward of the beige crane.
3.Threshing system
3.1 Pour the sterilized fruit in the fruit basket car into the unloading equipment.
3.2 Feed the fruit regularly into the fruit-separating machine to separate.
3.3 After twisting and beating in the fruit-separating machine, the fruits will fall off
entirely.
4. Pressing system
4.1 Palm fruit was transported to crasher by elevator.
4.2 Fruit was heated in crasher.
4.3 After sterilizing, the broken palm fruit flow into the palm oil press machine to
pressing oil and water mixture outflow from pressing chamber shell hole, in the same
time, the fiber cake and core was discharged from bonehead clearance and then drop in the packing anger of broken cake.
5. Fiber, cake, shell and kernel separation system
5.1 Fiber cake was dropped into packing auger, use interrupted blade to break up the
palm cake, evaporate the palm cake constantly during the transportation, and the enter
into the fiber and core separation machine. Use induced draft system which compose
of draught fan and wind net to transport fiber to boiler room to burn. Palm core of
large proportion drops into the bucket elevator from the other side of the fiber and
core separating machine and then to transport to the core charging bucket to dry.
5.2 Open the discharging hole which is at the bottom of the core chafing bucket, then
palm core drop into husking machine to husk.
5.3 Use shell kernel separator to separate the shell and kernel mixture after husking.
5.4 Kernel are charged into kernel holding tank and shell are transported to boiler room
to burn.
6.Clarification system
6.1 Use vibrated sifting filter to remove residues like fiber in the crude palm oil, then
the oil enter into the passivating tank.
6.2 There are indirect and direct steam in the passivating tank. After passivation, palm
oil and water mixture are banished to the high-order position tank and then flow into
the clarification tank.
6.3 Clarified oil flow into the oil tank, use disc separator to remove water in oil and
then use plate heat exchanger to eliminate the residual water completely.
6.4 After vacuum drying, the oil flow into net oil tank and then feed into the
final-product oil tank directly.
Refinery Process
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 degumming, manage the adding water
(there is a little 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 temperature needs to be higher than oil temperature.
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, mthen 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.
4.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.
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
vacuum 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. Then pumping the final oil into the oil tank.
Palm Oil Press Machine features as follows:
1) Compact and strong structure, and easy operation.
2) The automatic control system which can adjust barrel pressure.
3) High oil pressing efficiency, and residual oil in cake is less than 8%.
4) Low crushing efficiency for palm nut.
