Почему технология жаровыжимания нефти выше, чем производительность холодного?
Hot pressing oil production process than cold pressing oil yield is higher, mainly for the following reasons:
Oil viscosity reduction: When hot pressed, the oil will be heated to a higher temperature, generally around 100 ° C or even higher.
At high temperature, the viscosity of the oil is significantly reduced, the fluidity is enhanced, and it is easier to penetrate from the oil cells, thus improving the oil yield.
Cell structure damage: High temperatures can rupture the cell wall of oil cells, making it easier for oil to be released from the cells.
At the same time, high temperature can also denature the proteins in the oil, further destroy the cell structure, and create more favorable conditions for the outflow of oil.
Enzyme activity changes: Some enzymes in the oil will be activated at the appropriate temperature, and the high temperature conditions of hot pressing can change the activity of these enzymes to promote the release of oil.
Lipase, for example, breaks down fat at a certain temperature, making it easier for oils to free up and increasing oil yield.
Water evaporation: During the hot pressing process, part of the water in the oil will evaporate, which makes the structure of the oil become more loose, providing more channels for the flow of the oil, which is conducive to the separation of the oil from the oil, and thus improving the oil yield.
