초록

본 시험은 우리나라에서 원적외선을 이용한 이탈리안 라이그라스 인공건초 조제 가능성을 확인하기 위해 수행되었다. 본 시험에 사용된 기계는 온도, 송풍량, 원적외선 방사량을 조절할 수 있는 원적외선 건조기로 5월에 수확한 이탈리안 라이그라스를 대상으로 실시하였다. 건조를 위한 조건은 전체 9개의 조건을 선택하여 수행하였으며 각각의 조건은 방사율 42~45 %로 설정을 하였으며 내부 온도는 65℃로 설정하였다. 기기내의 기류의 속도는 40~60m/s로 하였으며, 전체적인 건조시간은 방사량 42%는 30분, 43%는 25분 그리고 45%는 20분으로 하여 수행하였다. 각각의 건조조건에 따른 최종 건물함량은 평균 88.5%로 나타났으며 전처리에서 건초에 적합한 건물함량을 나타내었다. 건조 조건에 따른 전력 소비량을 보면 45% 방사량에서 20분간을 건조한 처리구에서 가장 낮게 나타났다. 건조율에 있어서는 1~5번 건조 조건에서는 차이가 없었으나 6~7조건에서는 유의적으로 낮은 경향을 보였다. 사료가치에 있어서는 대부분의 건조조건에서 원물보다 CP, IVDMD는 높았고 ADF, NDF 함량은 낮게 나타났으며 대체적으로 4, 7 및 8번 건조 조건에서 높은 경향을 보였다. 이상의 결과를 통하여 건조속도, 전력량, 품질 등을 고려할 때 7 및 8번 건조조건이 가장 유리한 것으로 판단되었다.

This experiment was conducted to confirm the possibility of manufacturing artificial Italian ryegrass hay using far-infrared rays in Korea. The machine used in this experiment was a far-infrared ray dryer capable of adjusting temperature, airflow, and far-infrared radiation, and was conducted on Italian ryegrass harvested in May. Conditions for drying were performed by selecting a total of nine conditions, and each condition was set to emission rate of 42 to 45%, and the internal temperature was set to 65℃. The speed of the air flow in the machine was 40-60 m/s, and the overall drying time was 30 minutes for 42% radiation, 25 minutes for 43% radiation, and 20 minutes for 45% radiation. The final dry matter content according to each drying condition was 88.5% on average, and the dry matter content suitable for hay was shown in the all treatment. Looking at the power consumption according to the drying conditions, the lowest was found in the treatment that dried for 20 minutes at 45% radiation. In the drying rate, there was no difference in drying conditions 1 to 5, but a significantly low tendency was shown in conditions 6 to 7. In terms of feed value, CP and IVDMD were higher than raw materials in most drying conditions, and ADF and NDF contents were low, and tended to be high in drying conditions 4, 7, and 8. Through the above results, it was judged that drying conditions 7 and 8 were the most advantageous when considering drying speed, power consumption, and quality.
