The newly harvested peanuts have high moisture content,which often leads to mildew and serious economic loss due to its failure in drying time.As one of the important links of peanut post-harvest processing,drying is a necessary means to ensure the quality of peanut and prevent mould.The effects of internal factors such as structure,material composition,variety and external factors such as drying mode and technological parameters on the drying rate of peanut were systematically analyzed.The research status of the special drying technologies and equipments for peanut, such as hot air, heat pump and vacuum was described.Meanwhile the drying theory research such as the deterioration mechanism of peanut seed vigor,the research of automatic integration technology,and the development of bio-efficient,energy-saving and quality improvement combined drying technology and equipment were prospected,so as to provide reference for realizing the whole process mechanization and promoting the healthy and sustainable development of peanut industry in China.
