Introduction: The Importance of Precision Drying in Bean Drum Production
Bean Drum (Douchi), a traditional Chinese fermented soybean condiment, requires meticulous post-fermentation drying to preserve its unique flavor, texture, and shelf life. Traditional drying methods, such as sun-drying or coal-fired heating, often struggle with inconsistent temperature control, high energy consumption, and labor-intensive monitoring. These challenges can compromise product quality and increase operational costs. MeiYa Air Source Heat Pump Dryers offer a modern, energy-efficient solution tailored to meet the precise demands of Bean Drum production, ensuring optimal results while reducing environmental impact.
Advantages of MeiYa Air Source Heat Pump Dryers
MeiYa’s advanced heat pump technology revolutionizes Bean Drum drying with the following benefits:
- Energy Efficiency
Utilizing the principles of reverse Carnot cycle, MeiYa dryers absorb ambient heat to generate high-temperature airflow, consuming up to 70% less energy than conventional methods. - Precise Temperature & Humidity Control
Smart PLC systems enable multi-stage drying programs, maintaining ideal conditions (e.g., 35–50°C) to prevent over-drying or microbial growth. - Automated Operation
Reduced manual intervention with auto-stop features when target moisture levels are achieved, ensuring consistent quality batch after batch. - Eco-Friendly Design
Zero emissions, no open flames, and low-noise operation align with sustainable production standards. - Versatility
Suitable for small to large-scale facilities, with customizable drying room sizes and tray configurations to accommodate 500–2,000 kg of fresh Bean Drum per batch.
MeiYa’s Bean Drum Drying Process: A Step-by-Step Guide
1. Pre-Drying Preparation
After fermentation, evenly spread the Bean Drum on stainless steel trays (2–3 cm thickness) to ensure uniform airflow.
2. Initial Drying Phase (0–6 Hours)
- Temperature: 35–40°C
- Humidity: 50–60% RH
Gentle drying removes surface moisture without hardening the beans, preserving their enzymatic activity.
3. Main Drying Phase (6–18 Hours)
- Temperature: Gradually increase to 45–50°C
- Humidity: 30–40% RH
Intensify airflow to reduce internal moisture content to ~15%, enhancing preservation while retaining umami compounds.
4. Final Drying & Cooling (18–24 Hours)
- Temperature: Reduce to 30–35°C
- Humidity: <20% RH
Stabilize moisture to 8–10% for ideal texture. Cool naturally to room temperature before packaging.
