One of dephosphorization method

Hydration degumming method: this method is to use we mentioned earlier grease with moisture absorption and water absorption expansion principle of the principle to realize dephosphorization, this long process phosphorus, electricity, water, air, and the work, to discharge a large amount of sewage, oil loss big feet, although can remove contained in vegetable oil is given priority to with phospholipid colloid, but for peanut oil dehydration process, draught fanfull-bodied fragrance also be removed, this is because of peanut oil is thick fragrance of benzene acetaldehyde and pyrazine material by distillation volatile out when oil dehydration, which affects peanut oil concentration.So this method is the most unfortunately no flavor the oil get on price than a NongXiangHua source of value, so this method in the process of preparing NongXiangHua source, many manufacturers will not use.
Second degumming process is through the filter to achieve, it is the use of phospholipids in oil exists in the mixed micelles. http://www.palmmill.com/Products/prod/87.htmlTheir grain number between 180 nm to 200 nm, and the grain number than oil grain number (1.5 nm).The micelle through industrial filter paper and not dialysis principle, the key features of a layer of canvas available in test and production with a thin white cloth sandwiched between a layer of the compound filter medium industrial filter paper, through the test and production with the composite filter medium for rubber miscellaneous remove also has good effect, but this method degumming main factors is the kinds of filter medium and filter when MAO have certain conditions, the temperature of the oil layer sandwiched between a layer of canvas with a thin white cloth industrial filter paper composite filter, filter oil when the temperature is 20 ℃, 15 - hair oil cooling time for 30 min or so, to achieve the best effect, otherwise the phospholipid removal difficult to complete, this drawback is a waste of material...
