Product Description
Process Description:
Natural oil is a mixture of mixed triacylglycerol; Because of fatty acid chain length,
no saturation, the constitution and the location of a double bond and the fatty
acid distribution in triacylglycerol is different. Which make triacylglycerol
components exist differences in physical and chemical properties. Fractionation
is according to the melting point of difference in physical properties and its
solubility, make oil into solid, liquid (under a certain temperature).Despite two
operation of fractioantion and winterizationare similar, but it has different
purposes.
Freeze Crystallization
After heat change and heating, Oil is pumped to cystallizer. Starting the stiring and
chilling water circle pumop. Then the crytallization is beginning.when the chilled
water is not enough,open the chilled water to add.The design of crystallization
processing is based on ration of oleine, stearin and liquid oil.The whole
crystallization process is controled by computer curve.This ensure the crystal
maturing and furture filtering(crude palm oil refinery plant).
Filter
When the temperrature is reached to required remperature, the oil is pupmed to
filter. When the compressed air is ready, the filter start the squezzing,discharging
cake operation. When in the winter, we can use another filter to filter oil to get
required oil.after filtering, the oil is sent to storage tank. The stearin is melted.
Then sent to storage tank.
