Unlike ordinary nut traders that source raw materials from scattered third-party farmers, Wushi County Sunshine Agricultural Products Co., Ltd. operates large self-owned walnut orchards and modern automated processing factories, establishing a complete vertical industrial chain covering planting, harvesting, primary processing, fine screening and finished product delivery. Our professional agricultural teams harvest ripe walnuts directly from our own orchards at the optimal timing each harvest season, cutting out all intermediate distributors to ensure stable raw material supply and full product traceability. Immediately after harvesting, raw walnuts are transported to our factory for a rigorous multi-stage selection workflow: shelling, mechanical impurity removal, intelligent color sorting, manual secondary inspection and metal detection. We thoroughly eliminate shriveled nuts, broken kernels, moldy products and foreign impurities, reserving only the top-grade intact walnuts and walnut kernels for packaging and shipment to overseas customers. This farm-to-factory integrated model enables us to maintain consistent superior quality throughout the year, without relying on unstable external raw material sources.
