A machine like this can be used to extract oil from various raw materials, including peanuts, mustard, cotton seeds, grass seeds, flax seeds, etc. All contact parts of the automatic oil extraction machine are made from food grade stainless steel. The automatic machine has two vacuum filters. Compared to conventional machines, this high yield machine leaves less than 6% residual oil in the cake. Regardless of whether the machine is running or not, the cake thickness can be adjusted. A workshop built on only 10-20 square meters of land is enough for oil production. Vacuum oil filters remove all residual contaminants from oil. The surface of this automatic oil extraction machine is chrome plated SS in accordance with food hygiene standards.
