Скачать или смотреть Engineering Soft-Dried Longan: Inside a Heat Pump Dehydration Factory (2025)

Soft-Dried Longan is a premium dried fruit delicacy that requires precise control of temperature, airflow, and humidity to achieve its signature soft, chewy texture.
In this video, we take you inside one of the most advanced factories producing Soft-Dried Longan using modern heat pump dehydration technology in 2025.

The production of Soft-Dried Longan begins with ultrasonic cleaning to remove impurities, followed by automated pitting where each longan seed is removed with extreme accuracy. Unlike traditional high-heat drying methods, heat pump technology allows Soft-Dried Longan to dry gently at low temperatures, preserving its natural medicinal properties and honey-like sweetness.

Thanks to this controlled drying process, Soft-Dried Longan maintains a beautiful translucent amber color, a thin outer skin, and a thick, soft flesh that meets international export standards. Each piece of Soft-Dried Longan is inspected by AI-powered optical sorting systems to ensure consistent quality and appearance.

The entire facility operates under strict ISO and HACCP standards, using 304 stainless steel machinery and nitrogen-flushed packaging lines to maintain freshness without artificial preservatives. From industrial-scale tray loading to automated drying chambers, this documentary showcases how modern food engineering transforms traditional longan into a high-value export product.

Whether used for direct snacking or traditional herbal recipes, Soft-Dried Longan represents the perfect balance between technology, hygiene, and authentic flavor. Experience the scale, precision, and cleanliness of Factory 11/12 in this in-depth factory tour.
