Castor oil extraction machine
The working process of castor oil extraction plant:
1. To dry up the ripe castor seeds.
2. When they start to split open, to gather the seeds and dehull. Dehulling can be done by hand or by the use of peeling / hulling machine.
3. To clean the dehulled seeds, cook and dry these castor seeds before the oil is completely extracted. The cooking is done in order to coagulate the protein, which is necessary to allow efficient extraction, and to effectively press it.
4. To press the castor seeds that are pretreated before. This is normally done using a high pressure, which uses continuous screw press with the help of a seed oil press machine.
5. The castor oil flowed from castor oil extraction machine will be filtered.
The material which is ejected from the castor oil extraction machine is called the castor cake, which contains around 8-10% of castor oil. If we want to extract these castor oil, castor cakes should be sent into cooking oil solvent extraction plant with the use of heptane in order to extract the entire oil.
