When the kernels are sliced manually, it is tedious in time cost and difficult in control of product consistency. In this study, a mechanical system used for slicing of peanut kernels has been designed and developed. After tested, soak of peanut seeds mechanism with a touch Human-Machine Interface. Only need to press started key can be fully automated production, and user can setting all the steps during operation. This action can help to solve many environmental factors on the process. Peanut seeds available rate increased from 35% to 83%. Slicing mechanism prone to clogging and when it speed too fast, peanut sheets and debris will accumulated at the bottom of the slice mechanism. A peanut sheet is not easy to keep intact and some had been ruptured. Meanwhile, the knife material was evaluated and redesigned, the knife material changed to SUS 440C high carbon tool steel. The new slice institutions installed 6 blades; the blade’s tangent angle is 70°. Experimental results, the best cutting angle are 17 °. The slicing effects decline as the cutting angle to 22 ° or 27 °, respectively. When the rotary speed of arrives 1500 rpm, a complete slicing may be obtained and cutting thickness between 0.3-0.5 mm. The cutting capacity of this machine is around 60 peanut seeds per minute. The system is simple and safe in operation, easy to clean to keep hygiene quality, and suitable to be used by the small industries.
