Oil extraction machine production line adopts the most advanced extraction oil process to obtain edible oil with high quality, high safety and healthy. There has been up to 90% edible oil is processed through extraction with solvent addition.
We are experts in manufacturing and supplying a variety of oil seeds processing, crushing equipment and oil extraction machine in India. Our products are known for their superior qualities like sturdy construction, low power consumption, efficiency and long service life. Only high quality raw material and latest technology is employed in the production process. Moreover, we offer these products at affordable prices to make sure that they can be available by all the industries for a variety of applications.
Five common methods are used to extract oil:
a) Water assisted. Here the finely ground oilseed is either boiled in water and the oil that floats to the surface is skimmed off or ground kernels are mixed with water and squeezed and mixed by hand to release the oil.
b) Manual pressing. Here oilseeds, usually pre-ground, are pressed in manual screw presses. A typical press is shown in diagram 1.
c) Expelling. An expeller consists of a motor driven screw turning in a perforated cage. The screw pushes the material against a small outlet, the "choke". Great pressure is exerted on the oilseed fed through the machine to extract the oil. Expelling is a continuous method unlike the previous two batch systems.
d) Ghanis. A ghani consists of a large pestle and mortar rotated either by animal power or by a motor. Seed is fed slowly into the mortar and the pressure exerted by the pestle breaks the cells and releases the oil. Ghani technology is mainly restricted to the Indian sub-continent.
e) Solvent extraction. Oils from seeds or the cake remaining from expelling is extracted with solvents and the oil is recovered after distilling off the solvent under vacuum.
Most small enterprises will find that small expellers are the best technology choice. Methods such as water extraction and manual pressing only produce small amounts of oil per day, the extraction efficiencies are low and labour requirements high. Solvent extraction while highly efficient involves very substantial capital cost and is only economic at large scale. There are also health and safety risk from using inflammable solvents.
