When the food garbage of general hospital was dried by the rapid steam drying process, the water content was changed to 1.3% from 77.8~82.8%. In this experiment, weight reduction rate was 80%, and electricity consumption was 2.4Kwh. Dried compost from this rapid steam drying process was brown pellets, which was consist of 27.77% crude protein and 3.19% crude fiber. Even though these pellets were slightly short of crude fat and crude ash content, these were analysed as a possible supplementary feed for pig. On the condition of drying food garbage mixed with 5% pulverized chaff, the necessary drying time was shortened by 1 hour, weight reduction rate was 76%, and reduction rate of electricity consumption was 42%. But contents of crude fiber and crude ash were increased to about 2 times. In case of adding new food garbage continuously to the composted food garbage mixed with 3.4% pulverized chaff, weight reduction rate and contents of crude fiber and crude ash were decreased gradually, but contents of crude protein and crude fat were increased. In case of composting food garbage from buffet, both drying time and electricity consumption were reduced, and ingredients of compost were higher than that of assorted feed for pig in the market.
