How To Dry Wolfberry

2022-11-04

In the process of drying wolfberry, the biggest problem is to remove moisture and disperse water. Due to its large amount of water, during the drying process, if you are not careful, the accumulation and bonding of wolfberry will cause mildew and blackening. Therefore, in the drying process of traditional wolfberry, a large amount of artificial and paving area is required for high-frequency roasting, in order to prevent the accumulation of bacteria and reduce the yield. However, frequent sun exposure can easily lead to secondary pollution of wolfberry, so most of the wolfberry sold on the market have a small amount of black and scorched non-good products, which not only reduces the quality of wolfberry, but also affects consumers' consumption experience , has become the most troublesome problem for upstream manufacturers of wolfberry.


 The large-scale planting of wolfberry parks, due to the excessive concentration of the area and the large amount of daily harvest, cannot have a large area of the park for drying wolfberry. It also fails to meet the pollution-free health indicators. The preservation time of freshly harvested wolfberry is short, generally only two or three days. Therefore, the primary problem encountered during processing is the problem of dehydration and quality assurance.
