The history of the oil mill machine dates back to the ancient times when humans discovered the various uses of oil. One of the earliest forms of oil extraction was through the use of a traditional oil mill machine known as Kolhu or Ghani. Kolhu is a historical treasure of India’s oilseed industry, which has been used for centuries to extract oil from oilseeds.

Kolhu is a simple machine consisting of a large stone or wooden mortar and a pestle. The oilseeds are placed in the mortar, and the pestle is rotated to crush and grind them into a paste, which is then pressed to extract the oil. The oil extracted from Kolhu is pure, natural, and unrefined, making it a healthier option for cooking.

Despite the arrival of modern oil mill machinery such as oil expellers, screw presses, and solvent extraction plants, Kolhu still has a significant presence in rural India. The reasons for its continued use are not only historical but also practical. Kolhu is a low-cost and eco-friendly method of oil extraction, which requires minimum energy input and can be operated manually or with the help of animals such as bullocks.

Kolhu also has significant cultural importance in India. It is a traditional oil mill machine that has been used for generations in rural communities, and its usage is often associated with various festivals and cultural events. Kolhu has been a source of livelihood for many families, and it is an integral part of India’s rural economy.

However, the use of Kolhu has declined in recent years due to its low capacity, low efficiency, and high labor requirements. Modern oil mill machinery is more efficient and capable of processing larger volumes of oilseeds, which has made it a more viable option for industrial oil processing.

Oil mill machinery manufacturers in India offer a wide range of modern machines, including oil expellers, screw presses, and solvent extraction plants, which cater to the needs of small-scale and large-scale oil mill operators. These machines are designed to extract oil from a wide range of oilseeds, using various methods such as mechanical pressing, solvent extraction, and cold pressing.

In conclusion, the Kolhu oil mill machine is a historical treasure of India’s oilseed industry, which has played a significant role in the country’s economy and culture for centuries. Despite the arrival of modern oil mill machinery, Kolhu still holds cultural significance and remains a vital part of India’s rural economy. The usage of Kolhu may have declined in recent years, but its legacy and functionality continue to inspire generations to come.
