The invention relates to a hot
air drying technology and device for Chinese wolfberries. The technology mainly includes the following technological steps that first, raw materials are selected; second, the raw materials are cleaned; third, the raw materials are soaked into dewaxing
drying-promoting agent, and the cleaned Chinese wolfberries are soaked in the dewaxing
drying-promoting agent for 10 min to 20 min and then taken out; fourth, water draining off is performed, the Chinese wolfberries with water drained off are evenly arranged on the same layer of a same
drying screen and placed into a drying
bed, and then the drying
bed is placed in a drying chamber; fifth, reverse hot
air drying is performed, a reverse hot
air drying mode is adopted for controlling the temperature of the drying chamber between 45 DEG C and 50 DEG C, the
moisture is controlled to be about 30 percent, the temperature of the drying chamber is raised to be between 65 DEG C and 70 DEG C after two hours, the
moisture is controlled between 13 percent and 15 percent, and after the temperature and the
moisture are kept for 20 hours, drying is completed. Due to the adoption of the technological method, the temperature and the moisture in the drying chamber are balanced, drying consistency of fruit products is good, energy is saved, cost is low, and the
processing amount is large; dried Chinese wolfberries good in quality, low in mildewing rate and good in shape and color can be obtained.
