What is Cold Press Method?

Nowadays, specialists in oil extraction industry use several methods for gaining oil. One of them, which is much healthier and meets the standards, is cold press method. The oil extracted by cold press method is the best oil for edible use. In this method, oil is extracted from the seeds by mechanical pressure on oilseeds and fruits. The temperature of the extracted oil should not exceed over 120 degrees Fahrenheit (49 degrees Celsius).
The cold press oil has a pleasant taste and odor and its nutritional value is preserved. The amount of antioxidants and natural vitamins in the oil produced by cold press method is much higher than the antioxidants and vitamins in the oil produced by other methods.
Cold press is the best choice among different methods, this method does not use any chemical formula. In cold press, sesame oil is produced by applying pressure to the seeds at low temperature and without causing any damage to the texture of sesame seeds. In the next step, the waste is separated by a filter, and the oil of the desired quality is ready to use.

The Differences between Cold Press and Hot Press

• In hot press method, due to the increase in temperature, the oil with high temperature lose most of its benefits. But in the cold press method, the oil temperature is less than 45°C, which preserves the properties and benefits of the oil. In cold press oil extraction, the pressure applied to the seeds is without any heat, so the oil is free of any additives or chemical preservatives. In ancient times, the cold press method was called the mill method.
• The cold press machine works without bad smell and noise, and in addition, its power consumption is one-twentieth compared to the hot method.
• The macroeconomic effects of the cold press method are very significant.
• In cold press method, the oil is completely natural. These healthy oils are free of chemical refining and are 100% organic.
• There is very low depreciation on cold press machines.
• There is no environmental pollution and no use of fossil fuels.
• In the hot press method, heat is used to extract oil from the seeds. First the seeds are heated and then the oil is extracted by pressing them. This method usually uses a chemical called hexane. Hexane is a chemical solvent that combines with the oil in the seeds to draw out almost 100% of the seed oil. The oil obtained in this way is not edible and is considered a crude oil that must be refined and harmful substances removed in order to be usable. As the heat and the use of chemicals change the ingredients of the oil, in recent years with the advancement of technology, cold press machine is being used. Cold press machines separate the seeds' oil without heating and the use of solvents. In the cold press method, the oil usually has a maximum temperature of 30°C to 40°C, which does not cause any damage to the oil compounds. Of course, in cold press, 100% of the oil can not be extracted from the seeds, but instead the benefits of the oil are preserved.

Why Elements are necessary in Cold Press Method

An element heats the press cake. Heating the press cake up to 70°C makes it easy to get out of the mincing plate. At the same time, the temperature of 70 degrees does not burn the press cake in any way.
