Abstract
Authors developed two kinds of simple and low cost apparatus for fermentation of dairy manure slurry using solar energy. One (A type) of them is made in pipe frame construction covered by transparency film as a greenhouse; another (B type) is having wooden walls faced on north side, east and west side for thermal insulation and storage like a log house type. Thermal analysis for two type fermentation apparatus was done by simulation calculation. Consequently, the temperature of fermentation bag of the type A was kept over 113 days above 30℃, on the other hand, the fermentation bag temperature of type B was kept over 160 days above 30℃, and kept over 113 days above 35.℃ It was made clear that wooden wall type was excellent in the effect of thermal insulation and storage.
