The compositions of food waste were complex, and the content of organic matter was high, so food waste was suitable for being disposed with aerobic composting manner. Degradation time, strains inoculation quantity, waste moisture content and temperature of degradation were the main factors of affecting the food waste treatment effect and through the regulation of these factors can change the organic matter degradation ratio of biological degradation. Make use of existing food waste processing equipment to dispose food waste, the inoculation amount of food waste was in accordance with the ratio that auxiliary material (including bacteria strains): food waste =4:3, meanwhile, the degradation temperature was adjusted to 40°C, and the moisture content was changed to 40%. After 7 days, the output materials of food waste degradation would be used in the cultivation of vegetables as organic fertilizer.

Food waste is rich in nutrients. It can be disposed safely by biotechnology, which can make a contribution to environment, and avoid wasting resources. The bio-reactive food waste disposal processor basing on aerobic composting technology is designed in the research. The miniaturization and practical of it can be realized by studying its integrated form and structural components.

Reliability design is a new design theory and design methods with the modern science and technology developed. Food waste processing equipment is a new and efficient equipment used for food waste recycling. This paper briefly describes the design of mechanical reliability, and by describing the characteristics of food waste, described in the food waste processing equipment design, the need for the use of reliability design. To provide some basic reliability analysis for the future design of equipment.
