The wooden chekku machine, also known as the wooden cold press oil extractor, is a traditional and time-tested device used to extract oils from seeds like sesame, groundnut, coconut, and other oil-bearing materials. This method of oil extraction has been in practice for centuries, especially in South India, and is still cherished for its ability to produce pure, unrefined, and chemical-free oils. The use of a wooden chekku machine has gained renewed attention in recent times due to the increasing awareness of healthy living and the demand for organic, natural products.
How the Wooden Chekku Machine Works
The wooden chekku machine operates using the principle of slow, cold pressing. The machine is designed with a vertical wooden mortar (usually made from strong, durable woods like neem or vaagai) and a pestle, which is powered manually or by an electric motor. The seeds are placed in the wooden cavity, and the pestle rotates, applying gradual pressure on the seeds. As the seeds are pressed, the oil is slowly extracted without generating excess heat.
The cold-pressing process is key to preserving the natural nutrients and flavor of the oil. Unlike modern industrial methods of extraction, which use high heat and chemical solvents, the wooden chekku machine ensures that the oil retains its antioxidants, essential fatty acids, and vitamins, making it healthier for consumption. The oil produced is thick, fragrant, and has a rich taste, providing an unparalleled quality compared to refined oils.
