Soybean drying and processing techniques using recirculating batch dryer - reduction of broken grains by mixing soybeans with rice husks

摘要

To contrive a more effective method in applying the recirculating batch dryer used as rice and wheat also for soybeans drying use, the effects of the revolution rate of screw conveyer shaft in the drier and the ratio mixed with dry rice husks to soybeans were investigated on decreasing the rate of broken soybeans. The improvements on the recirculating hatch drier that the revolution rate of screw shaft was reduced to 200 rpm which is 45% rate from the standard revolution rate and the volumetric ratio mixed with rice husks to soybeans was 0.5 and above, resulted in the broken rate of soybeans less than 20% after elapsed 20-26 drying hours.
