Oil extraction by cold pressing method in Iran and the history of this method:
Today, oil extraction by cold pressing method is the most correct and healthy method of extracting oil from seeds, under pressure and without applying heat. In the old days, this method was called “Assari”. Assari was done in the oil mill or the oil mill, which was a special building with a high ceiling and huge millstone machines in the middle of the shop.
The old oil extraction method
In these old factories, they first washed the oil seeds and then poured it into the millstone. The millstone was also rotated by the power of animals such as horses, camels, mules, etc.Over time, they crushed them and produced oil from the seeds of the plant. Most of them were oil plant seeds: sesame, poppy, castor, sunflower, etc. The oil obtained from Asari was used in edible, medicinal and industrial uses. The remaining scum or flour was also nutritious food for livestock or was used as garden fertilizer.
This practice dates back to 1613 AD. On the basis of archaeological documents, including the existing Assarkhaneh, we can mention the Assarkhaneh of Isfahan. which is one of the tourist attractions of this province.
Over time, oil producing companies and factories that prioritized “full extraction of oil from seeds by any possible method” came to work. Every day harmful industrial products and as a result carcinogenic products were brought to people’s tables. While the Asari method was gradually forgotten.
Oil extraction by the modern cold press method
On the one hand, at the same time as the industrial revolution occurred in Europe and influenced by it, Mr. Anderson was able to introduce the oil obtained from cold pressing with mechanical machines into the food production cycle for the first time in 1876. These devices have undergone many improvements over time. Day by day, they moved towards lower energy consumption and higher product efficiency and health.
The arrival of oil extraction machines using the cold press method in Iran in 1996 was highly welcomed. Our country is considered as one of the most well-known producers of cold press oil extraction machines. Adrian Sanat Novin Mandegar is one of the largest manufacturers of cold press oil extraction machines. دIn this method, 100% organic oil is made available to the public, but this time with all hygiene and sterilized tools. Because the oil obtained in this method has a pleasant taste and aroma and does not contain any chemical additives and preservatives.
Cold press Oil extraction, compared to factory Oil extraction methods such as hot press, is only based on electricity consumption. As a result, the consumption of energy in the cooking of oil seeds, which is usually done by fossil fuels, is avoided. In this way, air, water and environment pollution and other side effects are prevented. Manufacturing factories using the cold press method are placed in the category of green industries.
