The most significant feature of the new quinoa dry processing technology is the addition of a conditioning and embryo fixation process and the replacement of the washing process with a humidification and polishing process. Without washing, drying, resource waste, or pollution emissions, and with low operating costs, the rice yield can reach over 85%, and the embryo retention rate can reach over 80%. Moreover, it can achieve the separate extraction and full recovery and utilization of all by-products, such as quinoa bran, husk, and residue.
Dry processing flow of new quinoa
Quinoa raw materials→ cleaning → conditioning and embryo fixation→ primary milling → secondary milling → humidification and polishing → color sorting → grading → packaging → storage
1.Conditioning and embryo fixation
Conditioning involves pre-treating quinoa through spraying and timed insulation to change its processing properties to meet the process requirements.
2.Embryo-retaining milling
The "multi-roller light milling" quinoa mill designed and developed by CPFMC can perform layered and moderate milling on quinoa that has been activated and fixed. This not only ensures uniform milling but also achieves a high embryo retention rate, nutrient preservation, and fewer broken grains. At the same time, the bran containing saponins can be collected separately to extract saponins to apply in the fields of agriculture, industry, and medicine.
