The crude vegetable oil from above mentioned two ways of extracting, oil pressing and/or solvent extraction, will be pumped into edible oil refinery machine to produce cooking oil at various grades. The main equipment of edible oil refinery machine is refining pot ,decolorization pot and deodorization pot. Edible oil refinery process flow chart: crude
edible
oil——degummming
machine——deacidification
machine——decolorization machine—— deodorization machine ——refine edible oil
General introduction of edible oil refinery machine： Alkali refining. Light up heat-conducting oil boiler, control heat conducting oil temperature of 98 degrees, and start the vacuum pump. Both low temperature and high temperature alkali refining are available basing on alkali concentration and oil temperature. High temperature alkali refining is only applicable for low acid value, light color, and low impurity crude oil refining.
Washing. Heat the oil until 90 degrees after soapstock release, and add hot water for washing and stirring. Control water temperature 5-10 degrees higher than oil, or emulsification. Continuously stir mixture 5 minutes, keep stand 4 hours, emit soap water, and wash repeatedly 203

times. Stir and dehydration for 1 hours after clear oil temperature warmed to 105 degrees. Washed clear oil can be inhaled into decolorization boiler for vacuum dying 30 minutes.
Decolorization. Vacuum pump with high vacuum of 700mmHg sends alkali oil to decolorization boiler. Keep stirring until temperature reaches 90 degrees, add decolorant (white clay, or active carbon) after moisture reduces less than 0.1%, and separate white clay from cooking oil by compressing air to oil filtration system to obtain decolorized cooking oil.
Evaporation and deodorization. Evaporate and deodorize the cooking oil simultaneously while high vacuum reaches up 755mmHg. It takes 4 hours for deodorization under 240℃/ 755mmHg, 260℃/759mmHg with continuous steam distillation.
Cooling and packaging. Close steam and heat-conducting oil, open cooling water valve, and close vacuum pump until oil temperature reduces to 40-80℃. Packaging refined cooking oil after sample oil inspection.
