연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Semiautomatic food frying apparatus is disclosed which provides apparatus which may be easily and safely operated to prepare small portions of various food products. In one embodiment, the food frying apparatus includes an upright cabinet with a fan assembly mounted to exhaust air through the top of the cabinet while drawing air in, through and from the lower portion of the cabinet. A removable one-piece filter unit is positioned in the path of air flow to remove odors, gases, smoke, etc. . . . from the air before the air is exhausted back into the room. The removable filter includes a paper filter together with activated charcoal particles configured as an integral unit. In another embodiment, the fan assembly and filter unit are replaced by a closed-loop air cleaning system which does not discharge the internal air of the apparatus into the room. A container for holding a supply of cooking oil is located in the lower portion of the cabinet. Mechanism is provided for automatically lowering a cooking basket, with food therein, into the cooking oil for a predetermined time and then raising the cooking basket from the cooking oil.
