Abstract
Citrus fruit (Citrus unshiu Marc) were stored in the facillity controlled with a microprocessor-based storage controller, and the respiration rate and weight loss of fruits were measured with the infrared gas analyzer and the strain gauge load cell. The storage conditions and measuring intervals were set by the keyboard of personal computer. The interfacing cicuitry between the computer and Z-80 microprocerssor was built with peripheral Interfacing It chips 6821 and 8255. The data measured were saved to a data file for recording and further analysis. When the fresh and bruised fruits were subjected to the storage condition for 4 days at 20 C, the respiration rate of the fresh one showed a stable value of 3-5ml
과채류 자동저장용 마이크로프로세서 제어장치를 활용하여 밀감의 저장시 발생되는 호흡량 및 중량감소를 자동 계측하였다. 중량감소는 스트레인게이지 load cell 장치를, 탄산가스는 적외선 가스분석기로 계측하고 계측신호를 컴퓨터에 접속하여 on-line화 하였다. 과일저장 조건과 계측시간 주기의 설정은 Z-80 마이크로프로세서와 컴퓨터간의 handshaking 정보교환 방식으로 수행할 수 있도록 하고 계측자료는 마이크로컴퓨터의 data file로써 자동기록 및 분석가능한 운영프로그램을 개발하였다. 건전한 것과 상처를 낸 감귤을
