The present invention can increase the milking yield of perilla oil while effectively reducing the content of benzopyran, which is a carcinogen that may occur during the production of perilla oil, A step of washing the washed perilla seeds by washing the selected perilla seeds, followed by soaking the washed perilla seedlings at a water temperature of 40 to 50 ° C for 1 to 2 hours to precipitate the perilla seedlings in a total amount of 100% % To 40% by weight, a primary roasting step in which the dried perilla seeds are roasted at 350 ° C to 370 ° C for 5 minutes to 7 minutes, A second drying step in which the temperature of the cooled bean curd is maintained at 15 to 20 DEG C for 11 to 13 hours, A step of separating the perilla and perilla bark by putting the perilla seeds into which the tea is dried, separating the perilla and perilla seeds, repeating the perilla seed and perilla seedlings three or more times in the automatic seeder to select the perilla seed and the perilla seed, To 250-2 A second roasting step of roasting at 70 ° C for 40 to 60 minutes, a step of transferring the roasted perilla to a breast milking machine through a screw transfer tube and a transfer and exhaust step of discharging the smoke inside the transfer tube to the outside using an exhaust device, A milking step of milking the perilla transferred to the milking machine while maintaining the product temperature of 200 ° C to 220 ° C using a hydraulic cylinder type milking machine； a precipitation step of precipitating foreign substances while maintaining the temperature of the milked perilla oil at 190 ° C to 210 ° C； And a filtration step of filtering the perilla oil from which the precipitated foreign matters are separated.본 발명은 들기름의 제조 공정 중 발생할 수 있는 발암 물질인 벤조피렌의 함유량을 효과적으로 저감시키면서도 들기름의 착유 수율을 증가시킬 수 있도록 한 것으로서, 선별된 통들깨를 정선 후 세척하여 세척된 통들깨를 물 온도 40∼50℃로 유지하여 1 내지 2시간 동안 침전시켜 불리는 불림단계, 상기 불린 통들깨를 총100중량% 중 잔류 수분함량이 30중량% 내지 40중량%로 건조하는 1차 건조단계, 상기 건조된 통들깨를 350℃ 내지 370℃로 5분 내지 7분 동안 볶는
