NOVELTY - Improving yield of sesame oil comprises (i) washing sesame, soaking, filtering, washing, drying naturally in drum drying equipment, heating, roasting and frying in microwave to obtain pretreated sesame; (ii) drying sepiolite powder, calcining, cooling, grinding, adding graphene, carrageenan and water, heating, stirring uniformly under ultrasonic vibration and vacuum drying; and (iii) pressing pretreated sesame seeds and prefabricated materials, followed by naturally settling and using plate and frame filter press at room temperature precision filtration to get sesame oil. USE - The method is useful for improving yield of sesame oil (claimed). ADVANTAGE - The method is simple, economical, has high oiling rate, physical and chemical indexes of sesame oil reaches national first and second grade, residual oil in filter cake is 10-14 wt.% and sesame oil production capacity is 174-182kg/hour and produces high quality sesame oil. DETAILED DESCRIPTION - Improving yield of sesame oil comprises (i) washing sesame, soaking, filtering, washing, drying naturally in drum drying equipment, heating, roasting and frying in microwave to obtain pretreated sesame; (ii) drying sepiolite powder, calcining, cooling, grinding, adding graphene, carrageenan and water, heating, stirring uniformly under ultrasonic vibration, removing carrageenan and water and vacuum drying; and (iii) pressing pretreated sesame seeds and prefabricated materials in vertical hydraulic press, followed by naturally settling and using plate and frame filter press at room temperature precision filtration to get sesame oil
