Description

Technical Field

[0001] The utility model relates to the technical field of sour jujube kernel production, in particular to a sour jujube kernel drying and screening device. Background Art

[0002] The seeds of Chinese jujube may contain a certain amount of water, and too much water will affect the quality and shelf life of the seeds of Chinese jujube, and even cause problems such as mildew. Therefore, in order to make the seeds of Chinese jujube longer, they need to be dried. Since the seeds of Chinese jujube may have particles of different sizes, in order to improve the uniformity and quality of the product, the seeds of Chinese jujube need to be screened to remove impurities and particles that do not meet the specifications, so that the product is purer and has uniform specifications. The existing Chinese jujube kernel drying and screening device (Announcement No.: CN217888603U) has the following disadvantages in use:

[0003] During use, hot air is added into the cylinder through the hot air interface to dry the sour jujube kernels. However, during the drying process, since the hot air enters from one position, the hot air cannot dry the sour jujube kernels on each screening net more evenly, resulting in some sour jujube kernels being dried faster and some being dried slower during the drying process, thereby prolonging the time of the entire drying process. For this reason, this patent proposes a sour jujube kernel drying and screening device to solve the above problem. Utility Model Content
