Product Overview
The GHG Series Rotary Steam Tube Bundle Dryer uses indirect steam heating — steam flows inside tube bundles while material circulates outside. Zero flue gas contact ensures clean, gentle drying ideal for heat-sensitive materials (DDGS, protein powder, germ, bone meal). Patented full-shell heat exchange reduces energy consumption to only 65% of conventional dryers (35% steam savings).
Key Advantages
1,Zero contamination — Indirect heating, no flue gas contact; products meet export feed/food standards
2,35% energy saving — Full-shell heat exchange; only 65% energy of conventional tube bundle dryers
3,Gentle drying — Precise steam temperature control; heat-sensitive materials retain full nutrition & value
4,Long service life — Tubes bear no material weight; ultra-low leakage; start under load
5,360° uniform heating— Rotating tube bundles stir material with zero dead zones
6,20+ materials — One dryer for DDGS, corn fiber, germ, bone meal, sawdust, cassava, straw, etc.
7,Evaporation rate up to 4.9 kgH₂O/m²·h— High-efficiency dehydration
Working Principle
1. Steam Entry— Saturated steam enters tube bundle via central shaft.
2. Indirect Heat Transfer— Steam condenses inside tubes; heat passes through tube walls to material outside.
3. Uniform Stirring — Drum rotates at 1–8 r/min; tube bundles lift, stir, scatter material for 360° heating.
4. Full-Shell Exchange— Entire drum shell participates in heat exchange.
5. Moisture Evaporation — Water evaporates; extracted by induced draft fan.
6. Continuous Discharge — Dried material + condensate exit separately.
7. Steam Recycling — Condensate returns to boiler.
