Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural product preparation technology, specifically a camellia seed shell sorting device. Background Technology
[0002] Seed and shell separation is a crucial step in camellia oil processing. It effectively separates the seeds from the shells of the camellia fruit to improve seed purity and provide high-quality raw materials for subsequent processing steps such as oil extraction. A screening method is generally used to separate the seeds and shells. This method utilizes the differences in shape and size between the seeds and shells, filtering them through sieves of different apertures. Camellia seeds are generally spherical or oval, with a diameter of about 10-20 mm, while the seed shells are irregularly shaped and larger in size.
[0003] However, existing sorting devices rely solely on sieves for screening, which has certain limitations. When the size difference between camellia seeds and shells is not significant, simple sieve screening may not be effective in distinguishing them, and the sorting accuracy is not ideal. During the sorting process, it is difficult to completely disperse the seed shells. Camellia seeds are spherical or oval with relatively smooth surfaces, while the seed shells are irregular in shape, with a certain degree of curvature and wrinkles. This irregular shape makes them easy to nest and stick together during the screening process. For example, when the seed shells wrap around the seeds, due to their shape fit, it is difficult to separate them by simple sieve vibration.
[0004] To address these issues, we provide a camellia seed shell sorting device. Utility Model Content
