A significant advancement has been achieved in our province’s agricultural processing sector with the successful application of a Belt-type Continuous Dryer for processing “Banxia” (Pinellia ternata), a key local medicinal herb. This technological leap marks a crucial step in promoting the deep processing of local agricultural products, adding significant value, and upgrading the entire specialty agricultural supply chain.

Technical Breakthrough: Precision Replaces Tradition

The drying process for “Banxia” is critical, requiring strict control over temperature, humidity, and duration to preserve its active compounds. Traditional sun-drying or rudimentary oven methods are inefficient, weather-dependent, and often lead to inconsistent quality, contamination, or loss of potency, ultimately reducing farmers’ profits.

The newly implemented Belt-type Continuous Dryer solves these issues. It features a multi-layer, evenly moving mesh belt that ensures continuous, automated operation from feeding to discharge. Its intelligent control system allows for  precise, zoned adjustment of temperature, air flow, and drying time, creating an optimal drying curve. This not only dramatically increases efficiency but also guarantees uniform drying, effectively locking in the herb’s medicinal properties and ensuring a standardized, high-quality final product.

Tangible Benefits: Adding Value and Empowering Industry

The adoption of this technology delivers immediate and multiple benefits for the local “Banxia” industry:

Superior Quality: Mechanical drying eliminates risks of mold and contamination associated with traditional methods. The processed “Banxia” exhibits excellent color, uniform texture, and consistent potency, easily meeting pharmacopoeia standards and gaining greater market acceptance.

Increased Profitability: The continuous operation significantly boosts daily throughput while reducing energy and labor costs per unit. The higher market price commanded by the premium product directly increases income for farmers and cooperatives.

Industrial Upgrade: The capacity for standardized, large-scale primary processing attracts attention and partnership from downstream pharmaceutical companies. This helps transform the province from a raw material supplier into a deep-processing hub, strengthening and expanding the local specialty agricultural economy.

The successful use of the Belt-type Continuous Dryer for “Banxia” is a practical example of empowering agriculture through technology and upgrading industry with advanced equipment. It addresses the core challenges of traditional herb drying and provides a replicable model for adding value to other high-potential local produce, injecting robust technological momentum into rural revitalization.
