An essential oil extractor, also known as an oil press or expeller, "squeezes" the oils from a plant product using high pressure and heat. These goods, which include seeds, nuts, vegetables, fruits, and leafy plants, release their oils mechanically, which is often done without the use of chemicals. One of the most important variables in determining the quality of essential oil is the process of extraction. Inappropriate extraction procedures can cause damage or alter the action of an essential oil's chemical signature. This results in a loss of bioactivity and natural characteristics. In severe cases, discoloration, off-odor/flavor, and physical changes such as increased viscosity may occur.
How does an essential oil extractor work?
A screw press is commonly used in electric essential oil extractor devices. To remove lightweight shells from the heavy nut, the peeling process may employ intense centrifugal forces or airflow from a fan. The product is supplied into the mechanical essential oil extractor screw system after peeling, which consists of a screw inside a high-pressure cylindrical chamber. As the material passes through the essential oil extractor still screw, friction, and heat are generated. While high pressure extracts the majority of the oil, heat also plays a role.
As the oil is extracted, it passes through a screen or filter to ensure that no particles or fibers are present. This results in a smooth, clean product. The residual squeezed seeds harden into a hard cake, which is removed from the essential oil extractor machine, and the oil drains into a separate container.
What are the parts of an Oil Extraction machine?
Home essential oil extractors and commercial essential oil extractors can be found in a variety of configurations, but one of the most common is the hopper, which is a metal structure that channels the raw ingredients into the screw press. The screw press is the oil expeller's engine. The screw shaft spins within a cylindrical cage, propelling the material forward in a high-pressure chamber. Friction occurs between the material, the screw shaft, the feedstock, and the press chamber. The glass essential oil extractor gear reduction unit, also known as the gearbox, translates the speed and torque of the electric motor to the correct machine settings.
