Sunflower seeds is a common oil seeds, in which there are 45-54% oil content. Sunflower oil, with golden color, clear and transparent, fragrance oil, is a kind of popular edible oil among people.
Main equipment of sunflower oil refining process:
degumming pot, deacidification pot, bleaching tower, deodorization pot, steam separator, gear pump, water pump, etc.
Decoloring tank: bleach pigments from oil.
Deodorizing tank: remove the un-favored smell from decolorized oil.
Oil furnace: provide enough heat for the refining sections which need high temperature of 280°C.
Vacuum pump: provide high pressure for bleaching, deodorization which can reach 755mmHg or more.
Air compressor: dry the bleached clay after bleaching.
Oil refining process flow:
Crude Oil→filtering→ Degumming→ Deacidification→ Water Washing→ Drying→ Bleaching/Decoloring → Filtration→ Deodorization→ Refined oil
- Sunflower Oil Refinery Process – Degumming
The purpose of degumming is to remove impurities such as phospholipids, gums and proteins etc. There are several methods as follows: water degumming, acid degumming, special degumming etc.
- Sunflower Oil Refinery Process – Neutralizing
The purpose of neutralizing is to remove free fatty acid in oil by using caustic soda while removing impurities such as phospholipid, pigments, metal ions, peroxide etc. by use of soapstock.
- Sunflower Oil Refining Process – Bleaching
High activity clay is added into oil. Mix and heat mixture of oil and clay to make the small particle of pigment absorbed on the crystal of clay. At last filter the oil. Mechanism, liable performance, well configured equipment.Bleaching Tower and Filters ensures excellent bleaching and separation effect.
- Sunflower Oil Refining Process – Deodorizing
Deodorizing is the final stage in oil refining in order to remove odoriferous material, free fatty acids and other undesired minor components by steam distillation under condition of high temperature and vacuum to produce a bland oil with a good shelf life.
- Sunflower oil refining process – Dewaxing(winterizing)
Through automation system, combined with crystallization curve (time-amount of crystallinity) of different oil, crystals in oil grow and finally can be separated by filtration to obtain dewaxed oil.
Application of sunflower oil refinery machine:
It can be used to process oil of Peanut, Coleseed , Coconut, Sunflower Seed,Soybean,cocoa, ; argan,sesame,black cumin,almond ,pomegranate seeds,Palm Kernal and other oil seed material.
