Resveratrol is a type of phytoalexin, which is produced by plants in response to injury or attack. Higher yields of resveratrol are obtained through soaking, slicing, and bioreacting. Currently, no automated processing systems for producing more resveratrol and stilbenoid have been developed. This study presents a comprehensive and complete automated machine for producing more resveratrol consistently. It is comprised of a soaker, a slicer, and a bioreactor for controlling the conditions of the environment and a grinder. Several parameters are considered to optimize the whole system. The temperature, humidity, and CO2 concentrations were 29.5 degrees C, 85%, and 815-850 ppm, respectively. From experiment results, the germination rate of the soaked peanut kernels reached 91.1% at 29.5 degrees C. The integrity ratio of the peanut kernels slicer was 95.2%, and the throughput of the slicer was 4.2 kg/h. High-performance liquid chromatography analysis showed that the quantities of resveratrol produced from mechanically treated peanut slices match those from manually treated peanut slices. Furthermore, scanning electron microscopy showed that the mechanically produced peanut slices exhibited smoother surface structures and more uniform thickness.
