The dehumidification temperature is 30-35℃ and the baking time is 12-15 hours. The dehumidification is completed when the moisture on the surface of the shell is lost and the color changes from dark brown to brown.
The second stage - color fixing and initial baking (50℃→12 hours) After dehumidification, it enters the color fixing and initial baking. The temperature rises to 50℃ and the baking time is 12 hours. The drying is completed. The characteristic is that there is no water vapor after cracking the drupe, the kernel has fixed color, 70% dry, but the kernel skin can still be removed.
The third stage - slow fire drying (30℃ → 16 hours) After the color fixing and drying period, the kernel drying period begins. The temperature is controlled at 30℃ for about 16 hours. At this time, the moisture content of the drupes reaches about 10%. After the kernel drying stage, the fire can be turned off, and the drupes on the oven are covered with burlap bags and kept warm for several hours to promote the continued evaporation of moisture in the upper drupes, so that the upper and lower layers of drupes are dried relatively evenly.
