Introduction to Lobelia (Roselle) Drying
Lobelia, commonly known as Roselle or Hibiscus sabdariffa, is a tropical plant prized for its vibrant calyxes and medicinal properties. Widely cultivated in regions like Yunnan and Guangdong, China, its dried flowers are used in teas, supplements, and cosmetics. However, improper drying methods can degrade its color, aroma, and nutritional value. Traditional sun-drying or coal-fired drying often leads to uneven results, contamination, or energy waste. This is where MeiYa Air Source Heat Pump Dryers excel, offering a modern, eco-friendly, and precision-controlled solution for preserving Lobelia’s quality.
Why Choose MeiYa Heat Pump Dryers?
MeiYa’s advanced heat pump technology revolutionizes Lobelia drying with these advantages:
- Energy Efficiency: Consumes 60–70% less energy than conventional dryers.
- Precision Temperature & Humidity Control: Ensures uniform drying and optimal retention of pigments and nutrients.
- Zero Pollution: Fully enclosed drying process eliminates dust or external contaminants.
- Automation: Reduces labor costs and human error with programmable settings.
Step-by-Step Lobelia Drying Process with MeiYa
1. Pre-Drying Treatment: Color Preservation
Lobelia’s signature red hue is sensitive to oxidation. MeiYa recommends:
- Enzyme Deactivation: Use steam blanching (95–100°C for 2–3 minutes) or microwave treatments to stabilize pigments and halt enzymatic browning.
- Uniform Sorting: Remove damaged flowers to ensure consistent drying.
2. Tray Loading Best Practices
- Material: Use MeiYa’s 304 stainless steel mesh trays to prevent contamination.
- Spacing: Arrange flowers in 8–12 cm layers across trays to promote airflow.
- Capacity: A standard 25 m³ MeiYa drying chamber holds ~800 kg of fresh flowers (8 trolleys × 12–14 trays each).
3. Smart Drying Stages
MeiYa’s programmable system automates the following phases:
- Phase 1 (Initial Drying):
- Temperature: 35°C → 38°C → 42°C (2 hours per stage).
- Humidity: 50% → 30%.
- Purpose: Gentle moisture removal to fix color and shape.
- Phase 2 (Intermediate Drying):
- Temperature: 46°C → 50°C (2 hours per stage).
- Humidity: 30% → 15%.
- Purpose: Accelerate drying without thermal shock.
- Phase 3 (Final Drying):
- Temperature: 55–60°C (11 hours) → 65°C (1 hour).
- Humidity: 15% → 8%.
- Purpose: Enhance aroma and ensure complete dehydration.
Total Time: 22–23 hours (vs. 3–5 days for traditional methods).
