2013 rice bran oil refining equipment

We have enough experience and advanced machinery for making rice bran oil, which lead the technicity in this field.

The rude oil from oil press or solvent process according to different capacity, which should be refined for better edible oil.

Normallythe capacity is from 2t to 500t per day.

description of rice bran oil making process

1. OIL PRESSING PROCESS:
Rice bran should be drying and frying for fresh rice bran, then store time is less than 3 days before pressing or it would become bad quality and effect the final oil quality.

The oil pressing plant is composed of cleaning process, drying units, pressing unit, conveyor, electrical cabinet box, etc. The oil pressing unit as the main stage, to make the embryo in a hardened cage to squeeze oil content out.
It's complete set of oil pressing equipment, which is automatically operated to save more labor and cost.

2. OIL SOLVENTING PROCESS:
Rice bran oil is separated from solvent by vaporizing solvent out. In configuring the solvent extraction plant, pre-pressing may be involved in which case seeds are lightly pressed, and which leaves about 14% to 18% oil in the pressed cake. Solvent extraction will further process these cakes and leave less than 1% oil in the final cake. This method results in higher yields, more oil; Lower power consumption, lower wear & tear / maintenance and high extract efficiency. Thus it could be used as complement equipment to extract the oil remained in cake, which yields are extra profits.

3. OIL REFINERY PROCESS:
The crude vegetable oil from above mentioned two ways of extracting, oil pressing and/or solvent extraction, will be pumped into oil refinery units to produce cooking oil at various grades.
The main equipment of oil refinery is various kinds of vessels and tanks carrying on different tasks with additives. These tasks may include sedimentation/filtering, neutralization (removing free fatty acid), degumming, decolorization (bleaching), deodorization, dewax etc. Different combination of steps and the treating degree of each step result in different grade cooking oil and salad oil.

Especially the dewaxing and winterization process is necessary for this kind oil.

Functions of rice bran oil refining equipment main parts

Refining section	used to P-acid de-gumming, alkali refining de-acid and water rinsing.
Decoloring section	used to remove off pigments, bleaching oils and grease dehydrate.
Deodorizing section	to remove off the odor components in oil.
Dewax	used to remove off the wax in the oil, in order to get the high quality oil.
Heat-transfer oil stove	supply each device production needing heat energy, temperature reach above 280°C.
Steam generator	produce the needing steam for de-odoring and distillation.
Vacuum pump	supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree can reach above 755mm Hg.
Press filter	filter clay, filter out clear oil.
Air compressor	blow dry bleached clay, blow empty the leftover oil in the press filter.
