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
  • How does a castor bean oil processor work?
  • Oil processors then heat batches of dehulled castor beans in steam-jacketed cookers or forced hot air vessels to remove moisture and harden the seeds for more effective mechanical pressing. Mechanical pressure is then used to crush the seed material and release the oil inside.
