12TPD Continuous Sphagnum Moss Dehydration Line – Southern Chile

Project Overview & Background

In 2018, a prominent horticultural exporter in Chile sought to modernize their Sphagnum moss processing. The primary challenge was the local climate; Southern Chile’s high rainfall and humidity levels made traditional air-drying impossible and caused processed material to “re-moisturize” before packaging.

Client Requirements:

• Quality Retention: Preserving the cellular structure of the moss to ensure high rehydration capacity (essential for premium export grades).

• Climate Adaptation: A system capable of discharging massive amounts of moisture quickly to counteract local high-humidity conditions.

• Versatility: The ability to process seasonal vegetables and fruits to maximize facility utilization during the moss off-season.

Customized Technical Solution

Guoxin Group engineered a Large-Scale Continuous Multi-Layer Mesh Belt Dryer specifically modified for the low-bulk density and high-moisture profile of water moss.

• Core Equipment: Guoxin Multi-layer Continuous Mesh Belt Dryer.

• Custom Engineering: Redesigned High-Volume Moisture Drainage Device. Our engineers increased the exhaust fan capacity and optimized the ducting layout to prevent internal condensation—a critical adjustment for the rainy Chilean climate.

• Temperature Control: Low-temperature high-airflow setting ($45\text{°C} – 60\text{°C}$) to ensure nutritional content and effective biological values are not degraded by excessive heat.

• Automation: Fully integrated PLC system for real-time monitoring of belt speed and humidity levels.

Performance & Operational Data

Cost-Benefit & ROI Analysis

Operational ROI:

Traditional moss drying in Chile is weather-dependent and labor-intensive. By switching to the Guoxin automated line, the client eliminated weather-related production stops. The Return on Investment (ROI) was realized in approximately 14 months, largely due to the ability to produce “Premium AAA Grade” moss, which commands a higher price in the Japanese and US horticultural markets.

Revenue Diversification:

The intelligent control system allows the client to switch to vegetable or fruit drying modes during harvest peaks, increasing the equipment’s annual utilization rate by $35\%$ and providing a secondary revenue stream.

Regional Policy Adaptability:

The equipment meets Chilean environmental standards for industrial emissions. The high-efficiency motor configuration aligns with local “Energy Efficiency” (Eficiencia Energética) incentives for industrial upgrades.

Customer Evaluation

“After conducting the initial test machine experiments with Guoxin, the quality of our dried Sphagna moss far exceeded our expectations. The engineers’ ability to redesign the moisture drainage system for our specific rainy environment was the deciding factor. The moss rehydrates perfectly, which is vital for our international customers.” — Project Lead, Chile Site.
