During the drying process, the apricot slices on the upper and lower layers of the grill should be exchanged to make it heated evenly, and strive to dry the same batch of raw materials at the same time. The drying time is generally 24-36 hours. If the temperature and humidity are not properly controlled, the drying time will be prolonged, and the color and luster of such products are poor and the quality is poor.
