An Oil Expeller, also known as an oil screw press, is a crucial industrial machine designed to efficiently extract crude oil from various oil-bearing seeds and nuts through mechanical pressing. It works by continuously pressing the raw material, separating the oil from the solid meal, and is fundamental to the production of edible oils and other oil-based products.
The expeller operates using a rotating screw shaft within a cylindrical cage or barrel. As the material enters, the screw's design gradually increases pressure, squeezing the oil out through narrow gaps in the cage, while the solid residue (oil cake) is discharged at the end. Key features often include robust construction from materials like high-grade cast iron, pre-conditioning sections for optimal oil yield, and adjustable choke mechanisms to control pressure and ensure maximum extraction efficiency for different seed types. These machines are adaptable for both hot and cold pressing methods.
Modern oil expellers are engineered for continuous, high-volume operation, focusing on energy efficiency, minimal maintenance, and user-friendly controls. They are available in various capacities to suit small-scale farm operations to large industrial processing plants, and often feature automatic feeding and discharge systems. Integrating an efficient oil expeller into an oil mill significantly boosts productivity, reduces operational costs, and ensures a consistent output of high-quality crude oil, which is vital for subsequent refining processes and market demands.
An Oil Expeller's primary function is to mechanically press and extract crude oil from various oil-bearing seeds and nuts, separating the oil from the solid meal.
Oil Expellers can process a wide range of oilseeds, including groundnut, mustard, soybean, sunflower, sesame, cottonseed, and more.
High oil recovery is achieved through optimized screw design, precise pressure application, and efficient pre-conditioning of seeds within the expeller.
