Methods and mechanism for drying scraps mulberry

In this paper, high temperature vacuum drying technique and microwave drying technique were compared in order to fast detect the moisture content of Scraps Mulberry, which was supposed to be the greater usage of natural resources. The research stressed on the effects of technological parameters such as initial weight and moisture content, temperature, vacuum, time, on drying results. Experimental results show that the drying curves of materials roughly include three stages of pre-heating, constant rate drying and retarded drying. In high temperature vacuum drying, temperature affects the drying speed more noticeably than vacuum. As a result, many advantages of microwave drying were found in this research, for example, rapid drying, precise detection of moisture content, extensive applicability to moisture, flexible usage of energy, etc. With the development of fast detecting moisture content of materials, microwave drying is expected to be the optimal detective method.
