Palm fruit oil and kernel oil process

Palm fruit oil and kernel oil process

1. Harvesting – the Palm oil is extracted from palm fruits and these plants grow in the tropics usually in Africa. The bunch is cut when the fruit is ripe and these fruit bunches are sent by trucks to the palm oil pressing plant.
2. Fruit Reception – the fruits arrived from the farm is dumped into a Fresh Fruit Bunch (FFB) hopper which is then transferred to fruit cages. The cages are then moved into a sterilizer.
3. Sterilization – the sterilizer acts as a pressure cooker where the fruits are heated with steam at a pressure of 45 psig for about one hour. This process softens the fruits enabling the separation of the fruit from bunches and stopping the enzymes that cause the increase of Free fatty acids in the fruits.
4. Threshing – in the next stage, fruit cages are tipped and moved to a threshing machine using the conveyor belt . The bunches get lifted up and dropped when they reach the top of the drum. This action helps the detachment of fruits from the bunches and the separated fruit lets fall through the slots of the drum to a conveyor below.
5. Pressing – The fruits are moved to a digester which mashes up palm fruitlets so that the oil is extracted efficiently. The output from the screw press is press cake and crude palm oil. The extracted oil is mixed with fruit particles, water, sand and dirt and the press cake is the transferred to the depericarpper for further processing
6. Clarification Station – The oil is pumped to a heated vertical tank where the separation of oil from the sludge takes place with the help of gravity. The oil is skimmed from the top and the remaining dirt is removed in a purifier. The heated clean oil is then passed to a vacuum chamber for the removal of the remaining moisture.
7. Press Cake processing – The press cake is moved through a conveyor that assists the break up of cake to a depericarper, which is a square box with a strong suction. The air removes the fibres and transports them to a cyclone. The nuts being heavier drop to the depericarper and are cleaned on a rotary drum and transported to a silo for intermediate storage.
8. Nut Processing – The nuts are first cracked in a nut cracker and the cracked mixture consists of kernels and shell which is then processed and separated. This is done in air columns and by a water bath in a hydro-cyclone. The kernels are dried in a silo and then packed in bags for sale and other factories extract oil from the kernel.  Huatai oil machine company supply different kinds of palm oil processing and different capacity palm kernel oil press, any need please email to [email protected]
