In order to improve the stabilized storage of wheat germ (WG) and better prepare it for further processing, a fluidization drying technology is developed to solve the problem of wheat germ' s acidification and deterioration. According to the WG character and the actual production, a multistage fluidized bed is designed and connected to wheat flour product line. With this equipment, temperature and airflow as major parameters are selected to test their respective influence on the wheat germ stabilization. The result shows that the optimized condition of fluidization drying is 45℃ of outlet temperature. VE loss of processed WG is 6.28%, and the decrease of NSI is 1.11%. No distinct change is observed in its fatty acid composition and relative content. After 30 days' accelerate store, peroxide value is 7.2 mmol/kg, and acid value is 18.47 mg/g. The experiment result shows that the technology and equipment developed have satisfied the demands of stabilized storage of wheat germ.
