rice bran oil mill
Rice bran oil plant set up by AGICO Group
Compared with other vegetable oils, rice bran is different. The rice bran doesn’t have oil extracted from seeds, rather it is obtained from the bran or hard outer layer of rice grains. The oil content of the rice bran is 15-23%. The chemical composition of the oil depends on the type of rice used and how it is treated and milled.
low initial investment
Compared with other oil extraction, starting a rice bran oil mill has a lower initial investment, especially in areas where rice bran is in plentiful supply.
high export rate
The demand for rice bran oil is increasing, especially in health-conscious regions such as North America, Europe, and parts of Asia. This export tendency could increase profitability.
efficient use of by-products
The rice bran is a by-product of rice processing. It is usually used for animal feed. Extracting oil from rice bran can increase its added value, reduce waste, and create additional extra income.
the process of rice bran oil mill
- step 1: Cleaning: the rice bran enters a cleaning screen, which cleans the sand, broken rice, grass rope, plant straw, and other debris contained in the rice bran. Then, iron impurities are cleaned with a magnetic separator.
- step 2: Conditioning: the rice bran is sent to a conditioner to preheat, adjust the rice bran water content and temperature, make it softer, and achieve it to a state suitable for oil production.
- step 3: Expanding: during the rice bran expanding process, the water inside the rice bran quickly evaporates and expands, forming a loose structure, this increases the rice bran surface area. When the rice bran is extracted from an expanding machine, the release of pressure causes it to expand further.
- step 4: Cooling: after expanding, the rice bran needs cooling, the expanded rice bran is cooled by a dryer, this is in favor of the rice bran’s stable structure and deactivation.
- step 5: Pressing or solvent extraction: strew pressing: it is suitable for small-scale oil mills (1-20tpd). Solvent extraction: to obtain higher oil yield and production efficiency, most industrial or commercial rice oil projects adopt solvent extraction, which is an ideal choice for large and medium-sized rice bran oil plants. The final product of solvent extraction is crude rice bran oil, generally 20-100 tpd.
- step 6: Refining: the rice bran oil refining process can be divided into two methods: chemical refining and physical refining. The main purpose is to remove impurities, improve flavor, and color and extend shelf life.

The cost of start a rice bran oil mill
Equipment cost
Starting a rice bran oil mill’s initial investment may vary depending on the size of the operation and location. Start a 10 tpd of plant estimate cost is around 20-25 million. Profit forecast may vary depending on sale, It sells for between $900 and $1,200 a ton. The net profit margin of rice bran oil can be around 10% to 15%.
Maintenance cost
When starting a rice bran oil mill plant should consider the cost of regular maintenance. Regular maintenance is important for the smooth operation of the plant and the quality of the oil produced. According to the severity of the problem, repairs can be costly. The cost of starting a rice bran oil mill has a big difference in plant scale and complex degree.
Other cost
In addition to plant costs, setting up a rice bran oil mill needs to consider other factors, these factors include labor costs, raw material costs, waste electricity, and other operating costs. The labor cost depends on the number of laborers and their skill level. Raw materials and electricity depend on the availability and location of resources.
The market of rice bran mill plant
With a annual growth rate of 2.74% from 2017 to 2022, the rice bran oil market was valued at US$ 6.57 billion in 2021. The market is projected to grow at a compound annual growth rate of 9.09% from 2023 to 2033, from US$ 7.84 billion in 2023 to US$ 18.85 billion.
Rice bran oil is extracted from the outer layer of germ and brown rice called bran. Because of its high smoke point, this oil favors high-temperature cooking and is mainly used for several cuisines of East and South Asian countries. The customer is growing awareness of the health of production-consumption, thereby increasing product sales.
Especially for consumers in Europe and North America, the demand for vegetable oil is increasing. This oil provides a cheaper and more suitable choice for consumers who like to cook with vegetable oil. In addition, this oil is suitable for cosmetic applications such as creams and oils.
the notes for Rice Bran Oil Extraction
- The rice bran has more starch, thus it is easier to become powder in the oil pressing process, causing gelatinization and blockage.
- The lipolysis activity of rice bran is high, is easier to perishable, is not suitable for long-term storage. So before the rice bran press, the rice bran should process and lipopidase (expanding), then rice bran is then used for oil processing.
- The rice bran has a large powdery degree and a small capacity, and the rice bran molding for oil pumping can improve the air permeability.
- The rice bran has complex content and high viscosity, comprehensive utilization should be considered in refining. Dewaxing process must be adopted in the refining process design of rice bran oil.
FAQ
Frequently Asked Questions about rice bran oil mill
What is the oil yield of rice bran and how to maximize it?
The rice bran in general has 15-23% oil. Generally, output could increase by suitable pre-treatment (expanding and conditioning) and advanced extraction technology to increase oil yield.
What can we offer capacity of the rice bran?
We offer capaciy of the rice bran is 1-20tpd by screw press. Solvent extraction is generally more than 100 tons/day.
