AI Technical Summary

Problems solved by technology

Since the fresh wolfberry peel is thin and easy to be mechanically damaged, which affects the appearance and integrity of the product, the fresh wolfberry fruit does not take long to clean after picking, resulting in incomplete cleaning, serious pesticide residues, and natural drying is easy to bring in dust, silt and other impurities

In order to improve the quality of dried goji berries, many goji berry merchants also try to wash the dried goji berries or semi-dried fruits for the second time. However, the skin of goji berries is damaged after the first washing and drying, and the sugar in the dried goji berries is easy to seep out after being covered with water. After secondary drying by conventional methods, the bonding between goji berries is lumpy, and it is difficult to obtain loose particles. Therefore, the drying method of dried goji berries after cleaning has become a problem that many goji berry processors have been discussing and researching.
