With the growing popularity of health-conscious consumption concepts and the ongoing transformation and upgrading of the edible oil industry, rice bran oil—a healthy edible oil rich in various bioactive nutrients such as gamma-oryzanol, Vitamin E, and plant sterols—is gaining favor among an increasing number of consumers. Rice bran is a byproduct of rice processing; notably, 64% of the nutritional content of rice grain resides within the bran itself. Against this backdrop, designing an efficient, intelligent, and stable large-scale rice bran oil production line is of paramount importance for rice bran oil processing enterprises seeking to seize market opportunities. Established in 1988, Henan Huatai Cereals and Oils Machinery Co., Ltd. possesses deep technical expertise and extensive engineering experience in the field of rice bran oil extraction.

Industrial Value and Market Prospects of Rice Bran Oil
Rice bran oil is a vegetable oil extracted from rice bran, a byproduct of rice processing. It is characterized by a high smoke point and a balanced fatty acid profile, making it suitable for a wide variety of cooking methods. Amidst national policies aimed at continuously promoting the development of the deep processing industry for rice grains, the rice bran oil sector is experiencing unprecedented opportunities for growth. Constructing a large-scale rice bran oil production line not only transforms rice processing byproducts from “waste into treasure” but also significantly enhances the added value and overall economic benefits of the rice processing industry.

Overall Process Design for Large-Scale Rice Bran Oil Production Lines
Large-scale rice bran oil production lines typically adopt a mainstream process route comprising “pretreatment and extrusion,” “solvent extraction,” and “fully continuous refining.” These lines offer daily processing capacities ranging from 10 tons to over 2000 tons. With a deep focus on the field of rice bran oil extraction, Huatai Oil Machinery has conducted extensive research into the specific characteristics of rice bran raw materials—specifically addressing issues such as susceptibility to rancidity, high pulverulence (fine powder nature), and moderate oil content. Based on this research, the company has custom-engineered highly optimized, intelligent production lines. Huatai Oil Machinery has successfully developed rice bran oil production lines with daily processing capacities ranging from 10 to 1000 tons, thereby effectively meeting the diverse requirements of clients across various operational scales.

Detailed Overview of Core Process Stages and Equipment Configuration
1）Rice Bran Pretreatment and Extrusion Section
Pretreatment constitutes the first critical stage in the rice bran oil production process. Due to the presence of highly active lipase in rice bran, the material is highly susceptible to rancidity and spoilage if not processed promptly, which severely compromises the quality of the extracted oil. Huatai Oil Machinery has independently developed a complete set of equipment for the puffing pretreatment of rice bran, a technology that has been awarded a national patent.
The primary process flow for this section is as follows: After undergoing cleaning and a bran-and-germ separation process to remove broken rice and impurities, the raw rice bran enters a magnetic separator to eliminate ferrous contaminants. Subsequently, it is fed into a extrusion machine for instantaneous treatment under high temperature and high pressure. This extrusion process effectively deactivates the internal lipase within the rice bran, thereby extending its storage life. As the puffed rice bran retains a relatively high moisture content, it undergoes drying in a plate dryer before being conveyed via a scraper conveyor to the rice bran oil extraction workshop. The key equipment configuration for this section includes: bran-and-germ separation screens, magnetic separators, softening and conditioning cookers, extrusion machines, plate dryers, and various conveying systems.
2) Rice Bran Oil Extraction Section
The extraction section constitutes one of the core stages in the rice bran oil production line; it utilizes organic solvents to extract oil from the rice bran, thereby maximizing the oil yield. Large-scale production lines typically employ the solvent extraction method, which offers significant advantages over the traditional pressing method—specifically, a higher oil yield and a lower residual oil content (approximately 1%).
The core equipment configuration of the rice bran oil extraction plant includes: a horizontal rotary extractor (or drag-chain extractor), a mixed oil evaporation system, a stripping tower, a solvent recovery system (comprising a desorption tower and an absorption tower), a DTDC wet meal desolventizing system, and condensers, among other components. The entire system integrates an intelligent control system to achieve fully automated operation—spanning the entire process from raw material pretreatment through to extraction—thereby significantly reducing labor and energy costs.
3) Rice Bran Oil Refining Section
The refining section further purifies the crude rice bran oil obtained from the extraction process, ultimately yielding edible rice bran oil that complies with national standards. Rice bran oil refining primarily encompasses six major processes: degumming, dewaxing, decolorization, deacidification, deodorization, and defatting.
The primary equipment configuration for this section includes: crude oil filters, heat exchangers, centrifugal mixers, alkali refining tanks, centrifugal separators, dewaxing precooling and crystallization tanks, decolorization towers and filtration systems, deodorization towers and condensation systems, winterization and defatting units, as well as various pumps, valves, and piping systems.

Recommended Configuration Schemes for Various Production Capacities
Based on clients’ varying capacity requirements and raw material characteristics, Huatai Oil Machinery offers customized design solutions for large-scale rice bran oil production lines. Our equipment capacities range from 10 to 2,000 tons per day; our basic configuration recommendations are as follows:
Medium-scale Line (Under 100 tons/day): Suitable for medium-sized rice bran oil processing enterprises. This configuration features cleaning screens, expanders, extractors, and semi-continuous refining towers. It involves moderate investment, offers flexible operation, and is well-suited for regional market positioning.
Large-scale Line (100–300 tons/day): Suitable for large-scale oil and fat processing enterprises. This configuration features a fully automated expansion-extraction production line and a fully continuous “six-stage” refining system. Integrated with a PLC intelligent control system, it achieves fully automated operation throughout the entire process. Residual oil content is controlled to below 0.1%, solvent consumption is reduced by 20%, and overall economic benefits are significant.
Extra-large-scale Line (300–1,000 tons/day): Suitable for massive rice bran oil processing hubs. Employing a modular design, this configuration features large-scale drag-chain extractors, multi-stage evaporation systems, and high-efficiency refrigeration absorption units. Supported by a PLC control system, it enables comprehensive process monitoring and remote operation & maintenance—from raw material intake to finished oil output.
