Core Technology & Innovations
- Adaptive Heat Pump Drying
Leveraging closed-loop heat recovery and variable-frequency compressors, the system reduces energy consumption by 60–70% compared to traditional dryers.
• Raisins Optimization: ◦ Low-Temperature Precision: Dry grapes (initial moisture: 75–80%) at 35–50°C to preserve natural sugars (fructose, glucose) and antioxidants like resveratrol. Adjustable airflow (12–18 m/s) achieves uniform <15% moisture in 18–24 hours, ideal for plump, non-crystallized raisins.
◦ Color Retention: Controlled humidity (20–30% RH) prevents browning, enhancing market appeal for organic and conventional batches.
• Green Beans Excellence: ◦ Two-Stage Drying: Pre-dry at 45°C to remove surface moisture, then stabilize at 55°C to reduce final moisture to <8% while retaining 90% of vitamin C and fiber. - Hygienic Industrial Design
• 304 Stainless Steel Trays & Chambers: Compliant with HACCP, ISO22000, and CE standards, ensuring corrosion resistance and allergen-free processing.
• Automated CIP System: Self-cleaning trays and ducts reduce cross-contamination risks by 50%, enabling seamless transitions between fruits, vegetables, and legumes. - Smart Automation
• IoT-Enabled Monitoring: Track real-time parameters (humidity, temperature, energy use) via a 7-inch PLC touchscreen with cloud-based analytics.
• AI-Driven Predictive Maintenance: Alerts for filter replacements and airflow adjustments minimize downtime.
Market Advantages
- Energy Efficiency & Rapid ROI
• Solar-Ready Integration: Optional solar thermal compatibility cuts grid dependency by 25–30%, qualifying for EU Green Deal subsidies.
• Scalable Capacity: Modular units handle 300 kg to 10 tons/day, achieving ROI in 12–18 months for high-volume operations. - Global Compliance & Certifications
CE-certified with Halal, Kosher, and USDA Organic endorsements, meeting stringent requirements for EU, North American, and Middle Eastern markets. - Multi-Product Versatility
From sun-dried raisins to crispy green beans and hybrid vegetable blends, the system adapts to diverse crops with programmable drying profiles, maximizing facility utilization.
Applications & Success Stories
- Raisin Valorization in California, USA
A Central Valley facility reduced drying costs by 40% while producing non-GMO raisins for global breakfast cereal brands, retaining 95% of polyphenols. - Zero-Waste Green Bean Processing in Mexico
A Sinaloa cooperative converted surplus green beans into shelf-stable snacks, cutting energy bills by 35% and achieving ISO22000 certification. - Hybrid Crop Drying in Spain
A Valencia plant dried raisins alongside tomatoes and bell peppers, optimizing energy use and tapping into the $12 billion Mediterranean snack market.
