Castor oil press machine is used for pressing castor bean for oil. There are semi-automatic castor oil press and automatic castor oil press. The castor oil produced is used for industrial applications and the residual oil rate is 6-8%. Castor oil machine features convenient operation, easy maintenance, and stable performance.
How does a castor seed extraction machine work?
Due to cooking, the oil droplets in the seeds come together and also the cell wall is broken, this results in improved oil yield and low power consumption. A continuous screw press is used to extract the oil. The castor seed passes through the machine where the screw shaft is rotated in the parallel direction and crushing the seeds.
Can castor seeds be used as raw material for castor oil press?
Castor Seeds obtained after the Cleaning process can be used as a raw material for Castor Oil Press. Castor seeds contain 45 – 50 % oil content. After two stage pressing, about 8 % residual oil is left in the oilcake/meal. The castor seeds are conditioned using Steam in a Cooking Kettle.
How is castor oil extracted?
The cooked seeds are then dried before the extraction process begins. A screw oil press machine is used to crush the castor oil-seeds to facilitate removal of the oil. The first phase of this extraction is called pre-pressing.
