The present invention relates to a method and a device for extracting and inoculating kefir grain&primes seeds from liquefied traditional kefir-fermented milk in which kefir grains are removed. A basic principle (an extracting and inoculating method) of the device of the present invention comprises: a method for artificially generating negative electrostatic attraction force and a hydrophobic property by using properties of hydrophobic surfaces of the kefir grain&primes seeds, and properties of the surfaces of the kefir grain&primes seeds which are charged with positive electric charges, and for attaching and extracting the kefir grain&primes seeds and a method for removing attached kefir grain&primes seeds by generating positive electrostatic repulsion force, and inoculating the same to milk. The device of the present invention comprises: a seed obtaining device unit which attaches and extracts the kefir grain&primes seeds by artificially generating the electrostatic attraction force and the hydrophobic property a constant voltage generating device unit which supplies high constant voltage to the seed obtaining device unit and a static electricity voltage adjusting device unit which is a switching circuit for converting polarity of static electricity voltage to generate attraction force and repulsion force in the seed obtaining device unit. The device of the present invention performs the attaching and extracting method with the properties of the electrostatic force and the hydrophobic property and easily extracts tiny kefir grain&primes seeds with a simple structure in comparison to a conventional mesh strainer filtration extracting device.COPYRIGHT KIPO 2017본 발명은 케피어그레인이 제거된 액상전통케피어발효유로부터 케피어그레인종자(kefir grains seeds)를 추출 및 접종하는 방법과 장치에 관한것이다.본 발명의 장치의 기본원리( 추출 및 접종방법)은 케피어그레인종자의 표면이 소수성의 성질과 + 전하로 대전되어 있는 성질을 이용하여 인위적으로 - 정전기력인력과 소수성을 발생시켜 케피어그레인종자를 부착추출하는 방법과 + 정전기력척력을 발생시켜 부착된 케피어그레인종자를 탈락시켜 우유에 접종하는 접종방법으로 구성되는 특징이 있다.이를 위해서 본 발명의 장치는 정전기력인력과 소수성을 인위적으로 발생시켜
