  • 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.
  • How does a screw oil press machine work?
  • 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. After pressing oil is collected and filtered and the filtered material is combined back with new, fresh seeds for repeat extraction.
  • How to make castor oil?
  • The castor oil seeds undergoes many processes to produce castor oil. The following steps: seed cleaning, seed cooking, oil extraction, oil clarification, oil storage and filling. Step 1: Castor Seed Dehulling Step 2: Castor Seed Cleaning Step 3: Castor Seed Cooking Step 4: Castor Seed Pressing Step 5: Castor Oil Clarification
  • What is castor seed oil production line?
  • This castor seed oil production line adopts mechanical oil pressing technology. It connects a series of seed processing equipment to continuous oil extraction which can largely saving labor cost in production. The castor oil seeds undergoes many processes to produce castor oil.
  • How is castor seed extracted?
  • Castor seed contains about 30%–35% oil. The extraction process begins with the removal of the hull from the castor oil seeds. This can be accomplished with the help of a castor seed dehuller. After removing the hull from the seed, the seeds are cleaned in seed cleaner, the equipment has screens of various sizes that can remove inorganic impurities.
  • What happens after pressing oil?
  • After pressing oil is collected and filtered and the filtered material is combined back with new, fresh seeds for repeat extraction. In this way, the bulk filtered material keeps getting collected and runs through several extraction cycles combining with new bulk material as the process gets repeated.
