Deodorization device structure design, related to the stripping process of vapor - liquid equilibrium.Good deodorization equipment, on the structure design, should be able to guarantee the stripping steam on the most ideal under the condition of phase equilibrium and free fatty acids and odor components of oil in various cases are only on a balance, palm oil plantso the steam consumption is bigger.And multi-stage counter-current circulation continuous deodorization tower, to establish a vapor - liquid equilibrium in each exchange level.
Therefore, the consumption of steam decreased obviously.In the process of stripping deodorization, evaporation efficiency changes according to the ventilation with the rate of water vapor.On steam rate increased, the evaporation efficiency is also increased.But on steam rate must be kept below the limits of oil began to splash phenomenon.In the process of stripping deodorization, in order to make the free fatty acids in the oil and odor components reduced to the required level, need to have enough steam by grease.Quantitative free fatty acids and odor removal components required for steam, as the oil content of free fatty acids and stink component in reducing.When free fatty acids in the oil and odor components content from 0.2% to 0.2%, removing the same amount of free fatty acids and odor components, the process of steam consumption will be the end of the steam consumption at the beginning of 10 times, therefore, should be paid attention to in the last stage of the deodorization, want to have enough time and enough steam.The size of the steam, not to make oil spatter loss greatly restricted.
draught fan
Reservoir depth of deodorization device for deodorization effect of considerable influence.Deep within the reservoir of absolute pressure is higher, so the unit steam volume is small.At the bottom of the reservoir in 2 meters deep into the steam, when the equipment maintain the absolute pressure of 1.3 kPa, steam pressure...
