Sesame Processing Plant Black sesame, white sesame seeds

      The process of hulling consists of preliminary cleaning and grinding, hot lye treatment, removal of the skin and pigments, thorough washing and drying.

　　Soaking process:The purpose of soaking is to make hull of sesame seeds soak in water totally for peeling off easily. The project use lye, soaking raw sesame seeds in a certain temperature, which improve the speed of infiltration ratio of water into the hull, shorten the soaking time greatly to 30-40 minute from original 7-8 hours.

　　Hulling process: The hull will be removed from the kernel by the relative friction between sesames by sesame hulling machine

　　Separating process: It is the key process in sesame seeds production, affecting the final yield of finished product. This plant uses separation theory by different geometrical sizes of hulls and seeds. It uses best soaking technology to soften hulls, then uses hulls smaller than seeds to take away the hulls with water flow in a subsidence-type automatic separator.

　　Washing process:The hulled sesame seeds are cleaned and shifted by sesame washing machine, which can remove the stones, mud, chaff, dust and any other impurities from the sesame seeds efficiently.

　　Drying process:The process use single chamber fluid bed drier. The sesame seeds float in hot air flow and polish by friction between seeds, which decrease sticky hull rate and improve the smoothness of finished product.
