Iran Cold Pressing Group built and put into operation Zeit Kerman factory in 1998. At first, this factory only produced crude oil by Hot Press method. But over time and seeing the weaknesses of this method in the amount and quality of the output oil, a decision was made to implement a new design in which the heat is removed from the oil extraction system and the process of oil extraction from the seed is done only under pressure. And making more than 20 test models and spending a lot of money, this work finally came to fruition and the first Cold Press oil extraction machine was made in Iran.
