In the rice bran oil processing process, the residual oil content in the extraction meal is a key indicator of production efficiency and economic benefits. Excessive residual oil not only wastes oil resources but also affects the quality and storage stability of the meal. As a leading enterprise in the grain and oil machinery industry, Henan Huatai Cereals and Oils Machinery Co., Ltd., with its years of technological accumulation and innovative research and development, provides a systematic solution to this industry challenge.

Analysis of the Main Reasons for High Residual Oil Content
High residual oil content in rice bran oil extraction meal is usually caused by the following factors:
1) Improper raw material pretreatment: Uneven rice bran crushing particle size, poor extrusion effect
2) Unreasonable extraction process parameters: Improper control of solvent ratio, extraction temperature, and time
3) Equipment performance limitations: Defects in the rice bran oil extractor design, poor mixing effect
4) Insufficient desolventizing and drying: Incomplete desolventizing of wet meal, residual solvent affecting subsequent rice bran oil processing processes

Henan Huatai Cereals and Oils Machinery Co., Ltd.’s Five Innovative Solutions
1) Intelligent Pretreatment System
The rice bran pretreatment system developed by Henan Huatai adopts multi-stage softening and precise conditioning technology to ensure that the rice bran reaches the optimal extrusion state. Its patented rice bran extruder equipment can increase the porosity of the material by 30%, creating favorable conditions for solvent penetration and fundamentally improving extraction efficiency.
2) High-Efficiency and Energy-Saving Rice Bran Oil Extractor
Huatai’s independently developed loop extractor adopts the countercurrent extraction principle. By precisely controlling the solvent concentration gradient, it reduces solvent consumption while improving extraction efficiency. The unique material layer design ensures sufficient contact between the material and the solvent, reducing the residual oil rate to below 1%.
3) Intelligent Temperature Control and Concentration Monitoring
The Huatai rice bran oil extraction system is equipped with advanced temperature sensors and concentration monitoring devices to adjust the extraction temperature, time, and solvent ratio in real time. The big data analysis system can automatically optimize process parameters based on raw material characteristics, ensuring that the rice bran oil extraction process is always in the optimal state.
4) DTDC Desolventizing and Drying System
Huatai’s patented DTDC (Desolventizing, Drying, Cooling) system uses low-temperature vacuum desolventizing technology to thoroughly remove the solvent while avoiding protein denaturation. The unique drying curve design ensures that the residual solvent in the meal is less than 300 ppm, significantly reducing the residual oil rate.
5) Fully Integrated Intelligent Control System
Huatai Innovation’s PLC intelligent control system integrates the entire rice bran oil production process of pretreatment, extraction, desolventization, and refining, enabling one-button operation and fault warning. The system automatically records and analyzes production data, providing a scientific basis for continuous optimization.
