Edible oil being an agro food product, it becomes very essential to maintain its quality. Oil expulsion is an abrasive process during which a lot of heat is generated. The heat can have an adverse effect on the oil produced in various ways. It may add an unwanted smell to the oil which would make it less acceptable in the market. Also, it may cause burning or charring of oil cakes and reduce the profitability of the mill.

Although Oil Pressing Machines have greatly mechanized in previous few years in the developed countries, certain developing countries still have a lot of scope for mechanization. Setting up oil pressing machines in parts of Africa, South America, Eastern Europe and some countries of Asia has become a booming business. Edible oil is a very important trade and market commodity which can be sold in various variants. People in the developed countries have switched to the use of refined edible oil, whereas in the developing country they have no option but to use the unrefined edible oil.
