Introduction
Longan, a cherished fruit widely cultivated in Southern China and Southeast Asia, is renowned for its nutritional and medicinal value. Proper drying transforms fresh longan into high-quality dried fruit (known as “longan fruit” or “gui yuan”), enhancing its shelf life and market value. However, achieving consistent quality demands precise temperature control and energy-efficient technology. MeiYa Air Source Heat Pump Dryers offer an innovative, eco-friendly solution that revolutionizes the traditional drying process, ensuring superior product quality with minimal operational costs.
Why Longan Drying Matters
Drying preserves longan’s natural sweetness, texture, and bioactive compounds while amplifying its economic value. Premium dried longan can fetch prices up to ¥18/kg in markets, making efficient drying critical for profitability. Traditional methods, however, face challenges such as high fuel costs, uneven heating, and labor-intensive operations. MeiYa’s advanced heat pump technology addresses these issues, delivering a cost-effective, automated, and sustainable alternative.
MeiYa Heat Pump Dryer: Key Advantages
- Energy Efficiency & Low Operating Costs
Unlike diesel, coal, or wood-fired dryers that incur high fuel expenses (e.g., ~¥1,000 for 2 tons of fresh fruit), MeiYa dryers use minimal electricity to power compressors, cutting energy costs by over 60%. - Precision Temperature Control
Maintain optimal drying conditions (60°C) with automated adjustments, eliminating the risks of overheating or under-drying common in traditional methods. - Zero Emissions & Eco-Friendly
No coal, diesel, or biomass combustion ensures no harmful emissions, aligning with global sustainability standards. - Fully Automated Operation
Eliminate manual monitoring—MeiYa dryers operate autonomously 24/7, reducing labor costs and human error. - Enhanced Product Quality
Uniform heat distribution preserves the fruit’s shape, color, and nutrients, yielding plump, golden dried longan with superior market appeal.
MeiYa Longan Drying Process: A 3-Stage Approach
Stage 1: Rapid Dehydration (0–6 Hours)
• Temperature: Initial high heat (65–70°C) rapidly removes surface moisture.
• Airflow: High-speed circulation accelerates water evaporation.
Stage 2: Moisture Redistribution (6–15 Hours)
• Temperature: Gradually reduce to 55°C.
• Key Step: Pause drying for 2–3 hours to allow internal moisture to migrate to the fruit’s surface. This prevents crust formation and ensures even drying.
Stage 3: Final Drying & Conditioning (15–25 Hours)
• Temperature: Stabilize at 60°C for uniform dehydration.
• Humidity Control: Intelligent humidity removal maintains ideal conditions until moisture content reaches ≤18%.
Total drying time: 20–25 hours, depending on initial fruit quality.
