Release time：2026-03-27
In late 2024, a leading agricultural enterprise in Sri Lanka required a transition from traditional sun-drying to a controlled industrial process. The tropical climate of Sri Lanka, characterized by high humidity and seasonal monsoons, often leads to post-harvest losses and inconsistent quality in medicinal herbs and livestock forage.
Client Objectives:
Consistency: Maintain the active ingredients (alkaloids/essential oils) in herbs through precise temperature control.
Scalability: Move from batch processing to a continuous 24-hour production cycle.
Policy Alignment: Meet the Sri Lankan Department of Agriculture’s standards for export-grade herbal products.
Sri Lanka Guoxin 15-ton mesh belt hay dryer installation site
Guoxin Group engineered a customized Multi-Layer Mesh Belt Dryer system specifically calibrated for the high-moisture content of freshly harvested forage and delicate herb structures.
Core Equipment: Guoxin 5-Layer Stainless Steel Mesh Belt Dryer.
Heat Source: Biomass Heat Exchanger (utilizing local agricultural waste to minimize fuel costs).
Material Compatibility: Designed for diverse feedstocks, including Moringa leaves, Lemongrass, and various Ayurvedic herbs.
Control System: Integrated PLC cabinet for independent belt speed and temperature zone regulation.

Investment Recovery:
Based on the local market price for high-quality dried Moringa and herbs in 2017, the plant achieved a Full Return on Investment (ROI) within 14–16 months.
Local Policy Adaptability:
The system’s use of a biomass heat exchanger aligns with Sri Lanka’s “Sustainable Energy Authority” incentives, which encourage reducing reliance on imported fossil fuels in favor of local agricultural byproducts (coconut shells, wood chips).
