We offer Dry Fractionation Plant to our clients. Dry Fractionation system is designed to process crude, ore-treated or RBD palm oil. This makes the entire process simpler with no environmentally hazardous waste produced.
The process consists of 5 stages:
- Heating the feed oil
- Formation of crystal by controlled cooling
- Crystal growth
- Maturation of crystals
- Filtration to separate olein and stearin
Filtration is effected by vacuum created by vacuum pump & the filtrate is collected in a receiver provided with a moisture trap. The vacuum is generated by water ring vacuum pump. The vacuum force creates continuous & constant suction head under the submerged portion at 20oC to 25oC of slurry. The vacuum sucks Olein into the receiver. Stearin forms uniform layer on the filter cloth fixed on rotary drum. As the drum rotates, progressive drying takes place at the end of the revolution. The cake is back blown with air and with the help of scrapper blade, the stearin is discharged in collecting tank, which is provided with steam heating arrangement for melting the stream, and then transported to storage tank by pump. The Olein in the form of filtrate is collected in the receiver and then transported to the storage tank.
