Detailed explanation of high-quality, premium chestnut shelling techniques

For chestnut shelling techniques after harvest, burrs that have already split open can be threshed in good time; unsplit burrs are piled in a cool, ventilated place so that they split open before threshing. This helps the nuts ripen and color after harvest and plays a certain role in improving chestnut quality. The burrs should not be piled too high, to avoid heating, mildew and spoilage. Chestnuts that fall free have a relatively high degree of maturity, but the water content of their embryos is also relatively high, and their physiological metabolism is still quite vigorous, so the heat released by their respiration is still relatively great. Therefore, the chestnuts should not be stored immediately, especially when storage conditions are relatively poor. The gathered chestnuts can be placed in a spot with good air circulation, where the relative air humidity is basically consistent with the water content of the chestnuts, and with good shade, and left to sweat for 1-2 days before storage; the storage results will then be better.
