vThe industry of dried tofu products wants to achieve breakthrough, the key lies in developing efficient processing equipments. Pressing equipment of dried tofu has been mostly designed according to the line - "manual design (some with a CAD) - prototype production - prototype testing - design modification". However this way not only gets a high cost of research, but also a long cycle. It used virtual prototyping technology, at first, according to the design requirements, created three-dimensional modeling by using Pro/E software; at last, made the feasibility analysis of kinematics and dynamics by using of ADAMS software. Through optimization design, analysis and control of cost, it had several characters as follows, simple machine, low cost, high productivity, it had great significance to mechanization and industrialization of pressing equipment of dried tofu.
