Abstract: The paper studied the processing of corrupt nut are excluded and wax skin is peeled and nut is roasted etc. The results show that corrupt nuts may be excluded highly by certain salt solution (by twice salt solution , culling coefficient is 99.62% by 1.125,1.131 salt solution respectively for first layer nuts;culling coefficient is 99.71% by 1.123,1.146 salt solution respec- tively for second layer nuts; culling coefficient is 99.57% 1.125,1.150 salt solution respectively for third layer nuts ;culling coefficient is 99.55% 1.123,1.146 salt solution respectively for fourth layer nuts ); wax is peeled by alkali solution ,dry time may be shorten by 1.5% alkali solution;by roasting,storage deadline of products may be guaranteed more than six months and hue may be preservated(yellow)by dry temperature of 100℃ and the dry time of 7.5h.

Key words: Henrychinkapin, produced by drying, hue, storage deadline
