Breakthrough in Konjac Drying Technology: ShouChuang Technology Helps Yunnan Farmers Increase Income by 30%
[Qujing, Yunnan, May 28, 2024] Domestic leading drying solution provider Nanchong ShouChuang Technology Co., Ltd. announced today that its self-developed "Konjac-Specific Heat Pump Drying System" has been successfully implemented at a demonstration base in Qujing, Yunnan. This technology improves konjac refining powder drying efficiency by 50%, reduces energy costs by 40%, and helps local cooperatives increase annual revenue by over 3 million yuan.
1. Challenges in the Konjac Drying Industry
-
Material Characteristics Challenges
-
Initial moisture content >85%, viscosity up to 5000mPa·s (prone to equipment adhesion)
-
Glucomannan heat sensitivity (degradation above 65°C)
-
-
Traditional Process Defects
-
Coal-fired drying causes sulfur residue (exceedance rate >15%)
-
Open-air drying limited by climate (mold loss rate 20-30%)
-
2. Innovative Solutions
2.1 Specialized Equipment Configuration
-
Model: SC-MagicDry 3000 Konjac-Specific Unit
-
Core Technologies:
✅ Anti-adhesion Teflon conveyor (adjustable spacing 1-5mm)
✅ Low-temperature dehumidification drying (35-50°C staged temperature control)
✅ Ultrasonic wall-breaking pretreatment (thins cell walls to accelerate dehydration)
2.2 Intelligent Drying Process
| Stage | Temp. | Humidity | Duration | Goal |
|---|---|---|---|---|
| Pretreatment | 45°C | 50%RH | 2h | Surface shaping anti-adhesion |
| Main Drying | 48°C | 30%RH | 10h | Glucomannan retention ≥90% |
| Fine Drying | 40°C | 15%RH | 4h | Moisture content ≤12% |
2.3 Quality Improvement Data
-
Product Whiteness: Increased from 65% to 82% (Japanese Grade A standard)
-
Viscosity Retention: ≥8000mPa·s (far exceeding national standard 6000mPa·s)
-
Sulfur Residue: Not detected (compliant with JAS organic certification requirements)
3. Economic Benefit Analysis
Investment Comparison (Based on daily processing of 5 tons of fresh konjac)
| Item | Traditional Coal Drying | ShouChuang Heat Pump System |
