The present invention relates to an environmentally friendly, yet robust deodorant and dehumidifying agent prepared by mixing extracted biomass and coffee grounds. The present invention comprises the steps of rotating the raw material receiving portion coupled to the raw material receiving portion coupling hole formed in the rotating milking portion of the milking machine; Injecting a vegetable raw material into the raw material receiving part through a hopper; Heating the vegetable raw material contained in the raw material receiving portion by the upper heating portion after rotating the raw material receiving portion to be located at the bottom of the upper heating portion of the milking portion; Rotating the heated raw material receiving portion and pressing the vegetable raw material contained in the raw material receiving portion by the pressing portion of the elevating milking portion to milk the oil; A tip purification treatment step of separating the residue components from the milked oil by a precipitation reaction; A reaction treatment step in which the vegetable oil obtained in the tip purification treatment step is subjected to precipitation treatment, decolorization and deodorization treatment, and acid value control treatment through PH change; A rear end purification treatment step of separating and refining the residue components, residual reaction substances, and separation substances from the vegetable oil obtained from the reaction treatment step by a precipitation reaction; Finally filtering the purified vegetable oil through the purification step to obtain a biomass; Mixing 5 to 10 parts by weight of the obtained biomass and 75 to 85 parts by weight of coffee grounds, and mixing 10 parts by weight of thermoplastic polyurethane (TPU) and 2 parts by weight of alumina (Al₂O₃); And compressing and molding the mixture of the biomass and coffee grounds into a press mold having a temperature of 100 to 180°C.본 발명은 추출된 바이오 매스와 커피찌꺼기를 혼합하여 제조한 친환경적이면서도 견
