Rehmannia is a precious traditional Chinese medicine. After harvest, it requires drying to remove excess moisture, extending its shelf life and preserving its medicinal properties. Therefore,
rehmannia dryer have become an essential piece of equipment in the processing of traditional Chinese medicines.
Currently, there are two main types of rehmannia drying equipment: rehmannia drying rooms and mesh-belt rehmannia dryers. Rehmannia dryers are versatile equipment for drying fruits, vegetables, and medicinal herbs at low temperatures. The dried rehmannia is golden in color, retaining its nutrients. The resulting infusion is golden in color and has a pleasant flavor, making it a popular choice among customers.
Rehmannia drying rooms can process materials ranging from several thousand to tens of thousands of kilograms per batch. For small and medium-sized farmers or pharmaceutical factories, this drying capacity is sufficient to meet daily production needs. In contrast, large mesh-belt rehmannia dryers are more suitable for large-scale production and processing. These dryers not only offer a larger single-pass capacity, but also operate continuously, enabling daily drying outputs of several or even dozens of tons. Therefore, their prices are correspondingly higher, typically ranging from tens of thousands to hundreds of thousands of RMB.
Rehmannia must be processed while fresh, and the roasting process typically takes 35 to 40 hours. Generally, five kilograms of fresh Rehmannia yield one kilogram of dried Rehmannia. Of course, this drying ratio also depends on the Rehmannia variety, moisture content, and drying process.
Rehmannia dryers can replace traditional drying methods like sun drying and earthenware drying, offering high efficiency, high yields, and low costs. How much Rehmannia can a Rehmannia dryer dry per day? This question depends on the type of Rehmannia drying equipment you use, as current drying equipment is not standardized and is customized based on demand and production volume.
