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.
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.
What is an expeller press?
An expeller press is a screw-type machine that mainly presses oil seeds through a caged barrel-like cavity. Some other materials used with an expeller press include meat by-products, synthetic rubber and animal feeds. Raw materials enter one side of the press and waste products exit the other side.
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
