Influence of peanut material characteristics on hulling performance

Peanut material characteristics mainly include peanut type and variety, peanut pods and kernels and physical and mechanical properties of peanut shells, peanut drying speed, humidity and temperature when shelling, pods uniformity and mixed conditions. U.S. researchers after a long period of actual investigation and experimental research found that the peanut's own physical properties, drying treatment, peanut moisture content and temperature, etc., on peanut shelling damage and efficiency are different degrees of impact; each variety of peanut has its own unique shelling characteristics, such as some varieties of peanut kernel cotyledons are more prone to cracking, red coat is more likely to break; peanut start date, picking picking date, the Harvesting methods and field peanut strip laying orientation, etc. have an impact on peanut shelling damage; the first shelling of unhulled peanut pods for the second shelling damage increase.
