The influencing factors of deodorization and smelting consumption

The amount of gas stripping deodorization deodorization increases the amount of gas stripping, higher velocity of steam, is conducive to the gas and liquid mass transfer in the process of deodorization process, can reduce the time of the deodorization.But easy to cause the neutral oil splash damage.In addition to guarantee the quality of gas stripping steam, steam with water, palm oil processing plantensure the steam drying, contains no air.The dosage of the direct steam is generally about 1% of the heavy oil.


Deodorization tower structure of deodorization tower with prevent splashing oil and distilled liquid reflux structure on reducing spatter loss and ensure the deodorization effect has obvious effect.The quality of the oil before and after deodorization For deodorization oil degumming, acid and decoloring treatment must be very good, remove the colloid, pigment and trace metals can have very good product.If the quality of the product requirement is very high, so the cost of deodorization and deodorization loss will be larger.The influence of metal ions Grease the metal ions are mainly iron, manganese, copper ions, calcium and magnesium ions, etc.,Steam pipe these trace metal ions is fat oxidation catalyst, especially under the condition of high temperature, in particular.Can by adding phosphoric acid, citric acid, etc to make metal ions, passivation.A workshop at the present stage of deodorization parameters and deodorization of the loss of soybean oil is now a workshop for example deodorization temperature: 245 ℃ ~ 250 ℃ deodorization time: 2 hours deodorization vacuum: 3 ~ 5 mba deodorization of gas stripping pressure: the first layer: 0.6 ~ 0.8;2 ~ 5 layers: 0.2 ~ 0.4;Layer 6:0.4 ~ 0.6 for deodorization oil layer of quality requirement: AV: about 0.2;Phosphorus: 1 ~ 2 PPM.Decolorizing color varies depending on the product requirements;Deodorization are usually the loss of about 0.3% ~ 0.1% general deodorizing distillate of the ratio of acid value and...
