To produce high quality olein and stearin Glamptech Dry Fractionation plant is custom designed to allow you to achieve selective crystallisation of different tryglycerides in edible oil. Glamptech Dry Fractionation plant you can count on producing stable and filterable crystals giving you a product to fit your standards and quality requirements. Glamptech Dry Fractionation system is designed to process crude, pre-treated or RBD palm oil. This makes the entire process simpler with no environmentally hazardous waste produced. The process consists of 5 stages.
Crystallisers are fitted with double row of circular cooling coil and a variable speed multi-stage agitator. Crystalliser are designed with a large cooling surface area, this ensures that the build-up of crystals does not occur. The variable speed agitatior contributes to gentle agitation, this keeps the oil mass moving without allowing stagnation close to the cooling coil. If you wish, Glamptech can also equip your Dry Fractionation system with a computerised distributed control system tailormade to your requirements. This combines all operations into a fully automated unit. We can accomplish filteration either with a Rotary Drum Vacuum filter, or a membrane filter press.

Consumption Figures, Per Metric Ton of Feedstock Steam Heating, 3 bars (based on 60°C Feed): 50 kg Cooling Water, 32 deg * C : 200 kg Electricity (including chilling): 15 Kwh Instrument air: 10 Nm3/hr
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 20 deg * C to 25 deg * C of slurry. The Vacuum sucks Olein into the receiver. Stearin forms unform layer on the filter cloth fixed on rotary drum. As the drum rotates progressive drying takes place at the end of 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 stearin, and then transported to storage tank by pump. The Olein in the form of filtrate is collected in the receiver and then transported to storage tank.
