500Tons per day rice bran oil refinery plant

Rice bran is the outer layer of the rice.It includes rice bran and rice germ.

Rice Bran Oil is truly "The World's Healthiest" edible oil, containing vitamins, antioxidants, nutrients and trans fat free. It's not just delicate and flavorful, it can help lower cholesterol, fight diseases, enhance the immune system, fight free radicals and more. Rice Bran Oil is extremely light, versatile and delicious. Use it to fry, sauté, in salad dressings, baking, dipping oils and where ever you use cooking oil. Once you use it you will be amazed cooking light and healthy is also the best tasting.

Composition of Rice Bran Oil 

Rice bran oil has a composition similar to that of peanut oil, with 38% monounsaturated, 37% polyunsaturated, and 25% saturated fatty acids. The fatty acid composition is:

   Rice Bran oil production line Introduction:

Rice bran→Magnetic separation→Cleaning →Extrusion Puffing →Counter-current

Main process description of  Rice Bran Oil for Oil Extraction Machine :

Cleaning process:

Adopt the magnetic separation removing iron miscellaneous and vibration sieve removing broken clear, rice Xi, etc.

Expanding process:

Adopting the expander can both improve the yield of rice bran oil and reduce the consumption. The extrusion puffing, on the one hand, can make solution lipase in the rice bran passivated under high temperature and high pressure condition,then prevent the rice bran oil rancidity; On the other hand, the extrusion puffing can make rice bran be porous mateial grain, and increases the materials bulk density, then improve the permeability and leaching rate which solvent reacts to the material.

 Drying process:

The puffed rice bran contains about 12% water, and the best moisture for leaching process is 7-9%, therefore, there must be effective drying means to achieve the best leaching moisture.Adopting counter-current dryer can make water and temperature meet with follow-up process requirements, and improve the oil yield, as well as oil quality.

Process feature:

1.Different combinations of process can process various oil plants in one workshop.

2. Extrusion treatment is used for raw materials with hard extraction, large-sized powder, and large capacity, which can reduce residual oil and solvent consumption, and increase the capacity by 50-80%.

Features of Oil Extraction Machine :

1. Adopt stainless steel fixed grid plate and increase the horizontal grid plates, which can prevent the strong miscella from flowing back to the blanking case, so as to ensure good extraction effect;

2. The rotocel extractor is driven by rack, with unique rotor of balanced design, low rotating speed, low power, smooth operation, no noise and quite low maintenance cost;

3. The feeding system can adjust the rotating speed of airlock and main engine according to the feeding quantity and maintain a certain material level, which is beneficial to the micro negative pressure inside the extractor and reduce the solvent leakage.

4. The advanced miscella circulation process is designed to reduce the fresh solvent inputs, reduce the residual oil in meal, improve the miscella concentration and save energy by reducing the evaporation capacity.

5. The high material layer of the extractor helps to form immersion extraction, reduce the meal quality in miscella, improve the quality of crude oil and reduce the evaporation system scaling.

1. Hydration Deguming & Alkali Refining Deacidification Process

2. Continuous Refining Decoloring Process

The main function of decoloring process is to remove oil pigment, residual soap grain and metal ions. Under negative pressure, the mechanical mixing method combined with steam mixing will improve the decoloring effect.

3. Continuous Refining Deodorizing Process
