Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, specifically a low-temperature drying device for shelling macadamia nuts. Background Technology

[0002] Macadamia nuts, also known as Hawaiian nuts or Queensland nuts, are a rare nut native to Australia and are known as the "King of Nuts." Their kernels are rich in nutrients and have a unique taste, making them one of the world's most popular premium nuts.

[0003] When processing macadamia nuts, they need to be shelled and then washed to remove impurities and dust from their surface. However, the washed nuts have water stains on their surface, increasing their moisture content. This not only increases the chance of spoilage but also makes them more susceptible to pests. Therefore, the nuts need to be dried. To ensure the taste and preserve the nuances of the nuts, low-temperature drying is necessary. Chinese Patent Publication No. CN 214207147U discloses a low-temperature drying device for macadamia nuts, including tray A, tray B, and a main body. The main body has a crossbeam and a longitudinal beam in its center. The crossbeam is installed inside the main body along its centerline, and the longitudinal beams are installed on both sides of the crossbeam, with one side connected to the main body and the other side connected to the crossbeam. Trays A and B are symmetrically installed inside the main body about the axis of the crossbeam. The bottoms of trays A and B are parallel to the horizontal plane. One side of each tray is hinged to the main body. Each side of each tray has a discharge port extending from inside the main body to the outside.

[0004] The aforementioned drying device uses two trays to hold nuts, and the steam heating pipes under the two trays can dry the nuts at a low temperature. However, the usable area of ​​the two trays of the aforementioned drying device is limited, and in order to ensure the drying effect, too many nuts cannot be placed on the trays at one time. In addition, new nuts to be dried cannot be added to the trays during the drying, feeding, and unloading processes. Therefore, the drying efficiency of the nuts is reduced and cannot meet the needs of large-scale nut production. Utility Model Content
