Stainless steel finned tube air heater is the core heating exchanger specially designed for industrial fruit and vegetable drying production lines and closed drying chambers. Powered by steam, hot water or thermal oil, this finned tube radiator heats circulating drying air evenly, creates constant-temperature dehumidification environment for dehydration of fruits, vegetables, mushrooms and agricultural products. All stainless steel construction avoids rust and chemical corrosion from acidic volatile vapor of fruits, fully complying with food processing hygiene requirements and helping processors reduce defective rate of dried food.
Working Principle
Hot medium (saturated steam / hot water) circulates inside stainless steel base tubes and releases latent heat or sensible heat. Heat transfers rapidly to outer stainless steel fins. Circulated air inside drying room cross flows over fin bundle and absorbs heat to form steady hot air. Constant hot air circulates continuously to evaporate internal moisture of fruits and vegetables; damp exhaust air is discharged by exhaust fan while new heated air supplements circulation, realizing low-temperature uniform dehydration of agricultural products.
Key Product Advantages
1. Food-Grade Anti-Corrosion & Sanitary Performance
Full stainless steel structure resists acid vapor and high humidity from fruit & vegetable dehydration, never rust or drop metal debris to pollute dried products, ensuring food safety.
2. Gentle Uniform Heating, Superior Drying Quality
Balanced air temperature without local overheating, effectively avoid scorching, discoloration and nutrient loss of fruits, retain original color, flavor and nutrition of finished dried fruits and vegetables.
3. High Heat Efficiency & Energy Saving
Enhanced fin heat exchange shortens drying cycle, improves daily processing capacity and cuts steam or hot water consumption for drying factories.
4. Flexible Installation & Space Saving
Modular design can be wall-mounted, overhead installed or fitted inside air duct, suitable for tunnel continuous dryer and batch-type static drying room of different sizes.
5. Low Maintenance & Long Service Life
Smooth fin surface is easy to clean accumulated plant dust; stable structure supports long-term non-stop continuous production operation.
6. Wide Heating Source Compatibility
Works perfectly with steam, hot water, heat pump and thermal oil heating systems to adapt local energy condition of different regions.
Application Scope
Dehydration drying for root vegetables, leaf vegetables, melons and fresh fruits
Mushroom, fungus, preserved fruit and dried vegetable processing production line
Low-temperature constant humidity drying workshop for agricultural by-products
