About Oil RefiningRefining is an essential process for a complete oil pressing line because there are still some impurities such as phospholipids,
FFA, pigment, odor,
etc in the crude oil. As a prominent oil press machines manufacturer who is devoted to processing pure edible oil for worldwide customers,we can provide professional technical support and manufacture firstrate oil machines for your edible oil refining.We can provide turnkey oil refining solution with capacities from 1-20T/D.1-20T/D Oil Refining Plants Features1. Wide application: various kinds of oil can be refined by our oil refining machines such as peanut oil, sunflower seeds oil, soybean oil, coconut oil, palm kernel oil, rapeseed oil, etc.2. The capacity of edible oil refining can be customized. The complete oil refining plant can work independently or together with the whole oil production line.Main
Steps of Edible Oil Refining1. Crude Oil Degumming: In this step
gums in crude oil are removed by hydration with the help of
phosphoric acid.2. Neutralization: In this step, free fatty
acids are neutralized by using sodium hydroxide and convert them
into soap. Additional impurities are also removed by
adsorption on the soap.3. Bleaching: During bleaching, unwanted
pigments are adsorbed physically and oil will become much
clearer.4. Deodorization: Deodorization is used to remove
unacceptable odors by steam distillation, the
odoriferous compound are stripped off with the help of live
injected steam into heated oil under high vacuum pressure.5.
Dewaxing (necessary for cold areas)Some kinds of oil like
sunflower, maize germ or corn oil have waxes inside, if these
impurities are not removed, the oil will freeze easily under
low temperature, thus affecting oil quality and appearance. so
this process is necessary for extremely cold areas.Edible Oil
Refining Equipment1. Decoloring tank: bleach pigments from
oil.2. Deodorizing tank: remove the un-favored smell from
decolorized oil.3. Oil furnace: provide enough heat for the
refining sections which need a high temperature of 280°C.4. Vacuum
pump: provide high pressure for bleaching, deodorization which can
reach 755mmHg or more.5. Air compressor: dry the bleached clay
after bleaching.6. Filter press: filter the clay into the bleached
oil.7. Steam generator: generate steam distillation.Part of Edible
