Usually there two main methd of extracting oil, they are mechanical pressing with expller press and chemical methos with with solvent. However for some seeds, such two stage processes (pre-press/solvent extraction) are now widely applied. What is Expeller Pressing?
What plants work with oil extraction machines?
Some of the plant sources that work with oil extraction machines include: Seeds: Oils can come from seeds like cottonseed, sesame, hemp, sunflower, amaranth and canola. They’re often used for cooking applications, but they can also be found in items like fuel and paint.
How do oil extraction machines work?
Oil extraction machines typically use a screw press. Some products, like groundnuts, need to be shelled or peeled before moving through the screw press. The peeling process might use powerful centrifugal forces or airflow from a fan to separate lightweight shells from the heavier nut.
What are the components of an oil extraction machine?
Oil extraction machines can come in several configurations, but here are some of the main components you’ll typically find: Hopper: The hopper is a metal structure that funnels the raw material into the screw press. Screw press: The screw press is the powerhouse of the oil expeller.
