The purpose of this research is that the heat from the cold water system is emptied by a vacuum dryer the microwave. [1] the study of drying drying peppers Kaffir lime leaves MOSS by the vacuum microwave model. [2] study the dried layer equations to find the appropriate equations describing drying chili Kaffir lime leaves Moss. [3] study on the multiplying images of chilies, Kaffir lime leaves and Moss: style and color surface. [4] study on the shrinkage percent moisture and absorbs water and dried chilies, Kaffir lime leaves, of MOSS, the temperature at 60 ℃ in drying and pressure in dryer 0.1, 0.2 bar study found that drying by using a saduai vacuum dryers, microwave to see if chilli Kaffir lime leaves and MOSS makes materials used in construction do not differ from past dialogues as best scent, scent that remains part of the material that is used in baking, it is not much shrinkage and reduces time to dry faster and use less power dryers vacuum so bahaeng the microwave.
