The present invention relates to a method of manufacturing a deodorant containing diatomaceous earth improved in deodorizing power and storage convenience, and a deodorant prepared by the method, comprising 50-70 parts by weight of diatomaceous earth, 3-10 parts by weight of zeolite, 5-10 parts by weight of calcium hydroxide, 3-10 parts by weight of calcium hydroxide, 3-5 parts by weight of potassium silicate, 3-8 parts by weight of Ililite, 1-3 parts by weight of natural cellulose fiber, 1-3 parts by weight of calcium sulfonate, (S10), 0.5-2 parts by weight of starch is dissolved and dissolved in 2-8 parts by weight of water (S20), and the starch water is mixed with the raw material mixture to prepare a raw material mixture (S30) for forming a kneaded product, a molded body refolding step (S40) for molding the kneaded material to form a ring-shaped molded body, and a step of heating the refolded molded body at 30-60 DEG C for 1-2 hours (Step S50). It achieved by also. According to the present invention, the deodorant can be further improved in deodorizing property as the outer surface of the deodorant is formed into a small-sized annular shape and the specific surface area is increased. Further, since volcanic ash can be further added, The volatile organic compounds are removed by the nature, and the antimicrobial function and the other components have an effect of adding deodorization, far-infrared radiation and anion generation functions.본 발명은 탈취력 및 보관편의성이 개선된 규조토를 함유하는 탈취제 제조방법 및 이에 의해 제조된 탈취제에 관한 것으로서, 전체 100중량부에 대해 규조토 50-70중량부, 제올라이트 3-10중량부, 알루미노실리케이트 5-10중량부, 소석회 3-10중량부, 포타슘실리케이트 3-5중량부, 일라이트 3-8중량부, 천연 셀룰로즈 화이버 1-3중량부, 칼슘설포네이트 1-3중량부, 허브 분말 1-5중량부를 혼합하는 탈취제원료 혼합단계(S10), 전분 0.5~2중량부를 물 2~8중량부에 풀어 용해시키는 전분반죽물 제조단계(S20), 상기 전분물을 상기 원료혼합물과 혼합하여 원료반죽물을 만드는 원료반죽물 혼합단계(S30), 상기 원료반죽물을 성형하여 환 형상으로 성형체를 만드는 성형체 제환단계(S40), 및 상기 제환된 성형체를 30-60℃에서 1-2시간 동안 건조시키는 환 성형체 건조단계(S50)를 포함하여 이루어진다.본 발명에 따르면, 특히 탈취제의 외관이 작은 크기로 환 형상으로 형성되어져 비표면적이 커짐에 따라 탈취성이 개선되는 효과가 있으며, 화
