A mustard oil expeller is a machine used to extract oil from mustard seeds. Mustard oil is a vegetable oil that is popular in some regions of the world, particularly in South Asia. It is used for cooking, as well as for medicinal and cosmetic purposes.

The mustard oil expeller typically consists of a crushing chamber, an oil extraction screw or press, and a motor or power source. The crushing chamber is where the mustard seeds are loaded and crushed to release their oil. The oil extraction screw or press applies pressure to the crushed mustard seeds to extract the oil.

A filter press is a mechanical filtration device used to separate solids from liquids, typically in industries like food processing, chemical production, water treatment, and oil extraction. The machine works by applying pressure to a slurry (a mixture of liquid and solid particles) and forcing the liquid through a filter medium, leaving the solid particles behind.

The filter press consists of a series of plates, each covered with a filter cloth. These plates are arranged in a frame, creating chambers where the slurry is pumped in. When the machine operates, hydraulic or mechanical pressure is applied to the plates, compacting the filter cloth and ensuring that the liquid passes through the filter, while the solids are trapped in the chambers. The separated liquid, now clarified, flows out through drainage channels, while the solid residue, often called "cake," accumulates inside the chambers.

In the context of oil extraction, a filter press is often used to purify the oil after the initial extraction process. After oil is squeezed out of seeds (such as in a screw press or hydraulic press), the oil may still contain impurities or small solid particles. The filter press helps remove these, ensuring that the final oil product is clear, clean, and of high quality.

Filter presses are known for their high filtration efficiency, ability to handle large volumes, and capability to filter a wide range of materials. They are especially valuable in applications where clarity and purity of the liquid are essential, and the separation of solid and liquid phases needs to be done efficiently and cost-effectively.

A domestic oil expeller is a small-scale, user-friendly machine designed for home use to extract oil from various oilseeds like sunflower seeds, sesame, peanuts, mustard, and more. It operates using a screw press mechanism, where the seeds are fed into a barrel, and a rotating screw applies pressure to extract oil. The extracted oil is filtered and separated from the residual cake.

Domestic oil expellers are compact, energy-efficient, and typically require minimal space, making them ideal for households or small-scale kitchens. They allow users to produce fresh, pure, and chemical-free oil at home, which is healthier and more cost-effective than buying commercial oils. These machines are easy to operate, with some models offering adjustable settings to control the oil extraction process based on the type of seed being used.

In addition to oil extraction, domestic oil expellers can also be used for making cold-pressed oils, which retain more nutrients and antioxidants, enhancing the flavor and quality of the oil.
