1. Functional Rapeseed Oil 7D Process Technology Roadmap
2. Functional rapeseed oil 7D technology
1 Featured technology
Based on the difference in physical and chemical properties of rapeseed, such as shape, size, density, etc., it integrates the functions of screening, winnowing, magnetic separation, stone removal and dust removal, and efficiently separates flying rapeseed impurities, and selects less than 0.1% rapeseed impurities.
2 Microwave quenching and tempering technology
Coupled with microwave physical field and hot air heat and mass transfer, energy consumption is reduced by more than 20%, and high-efficiency conditioning of rapeseed, cell micro-expansion, inactivation of endogenous enzymes and efficient production of canolol are realized.
3 Low temperature and low residual oil pressing technology
The automatic low-temperature and low-residue oil press, which integrates the shear cone, the automatic cleaning of oil residue and the back-squeezing mechanism, realizes the automatic low-temperature and high-efficiency pressing of rapeseed. The pressing temperature is <90℃ and the residual oil of rapeseed cake is <7.5.0% .
4 Low temperature green refining technology
Based on selective physical adsorption of impurities such as phospholipids and free fatty acids, it integrates pneumatic automatic feeding and intensified stirring to achieve one-step low-temperature physical refining, and the refining temperature is <45°C.
5 Fragrance and flavor technology
Based on microwave aroma, promote Maillard reaction, produce pleasant flavors such as roasting aroma, avoid spicy green flavor, make the flavor pure and strong, and achieve high-quality and fragrance retention throughout the process at low temperature.
6 Standards and quality control technology
Based on the quality standards and production technical specifications of functional rapeseed oil, combined with digital remote transmission, wireless transmission and Internet cloud technology, it realizes APP remote product quality and standardized management.
7 Remote technology and management technology
Based on the principle of distributed system control, it integrates the three-layer network architecture of sensors, PLC, central server control system and the Internet of Things perception system to realize real-time perception and monitoring of production.
3. Functional rapeseed oil 7D technology is light, green, low-consumption and high-efficiency
1. Light and simplified process: the process is reduced by more than 50% compared with salad oil, which occupies less land and saves investment;
2. Green production: physical squeezing and refining, no chemical addition, no three wastes discharge;
3. Technical standardization: modular production, reducing energy consumption by more than 20% and cost by more than 30%;
4. Production automation: the process is simple and efficient, the quality is stable, and the product yield is high;
5. High-value products: safe and nutritious, rich in fragrance, pure color, mellow taste, rich in active functional nutrients, it is a functional Chinese good oil.
4. Functional rapeseed oil is safe, nutritious, good in color, fragrance and shape
