The methodical design of a dehuller for using in soybean processing is described. The long term objective of the project was designing of a centrifugal dehulling system in soybean processing by development of a concept solution. The distinguishing feature of the described design procedure was the use of a structured design approach, which forces the designer to methodically review and compare alternative solution options, thus preventing the selection of solutions based on prejudice or belief. The unit consists of two main parts: the dehulling set and the power transmission system. The dehulling set consists of a rotating drum and a separate rotating circular base–plate. These two parts rotate in opposite directions, employing two separate electrical motors. Some of the advantages of this new machine are simple mechanisms, avoiding from using any complex part, capability of automation, simple usage, simple maintenance and finally low cost of the machine.
