High-Efficiency Pre-Drying System for Oil Residues Before Solvent Extraction
It is specifically designed to overcome common issues of conventional rotary drum dryers, including material sticking, agglomeration, blockage, uneven drying, excessive energy consumption, and unstable operation.
Typical Applications
Olive Pomace
High moisture, high fiber, strong stickiness, easy agglomeration
Palm Fruit Residue / Palm Fiber Cake
Coarse fiber structure, high moisture load, difficult hot-air penetration
Coconut Cake
High residual oil content, mixed particle structure, localized wet zones
These materials share common challenges:
high moisture + residual oil + complex fiber structure, making them difficult to dry efficiently with traditional drum dryers.
How QIE New-Type Dryer Works
Reinforced hot-air convection design
Improves heat-transfer efficiency and evaporation rate
Continuous agitation and dispersing system
Breaks lumps, prevents wall sticking, and enhances material movement
Suspended material curtain (quasi-fluidized state)
Ensures fast and uniform moisture removal
Stable continuous discharge
Provides consistent feed conditions for downstream solvent extraction
Result: faster drying, lower energy consumption, and improved extraction performance.
Key Technical Performance
Feed moisture range: 25% – 58%
Final moisture after drying: ≤13% in one pass
(can be further reduced depending on material and configuration)
Typical capacity range: approx. 0.5 t/h – 10 t/h and above
Compared with conventional rotary dryers:
Capacity increase: +50–70%
Power consumption reduction: ~50%
Thermal energy savings: ~60%
Overall operating cost reduction: ~30%
Low odor, low dust, easier exhaust gas management
Material-Specific Advantages
Olive Pomace
Enhanced agitation and material curtain formation prevent sticking and agglomeration, improving drying uniformity.
Palm Fruit Residue / Fiber Cake
Multi-stage agitation improves fiber turnover and hot-air penetration, resulting in higher drying efficiency.
Coconut Cake
Suitable for use with upstream size control or pre-crushing, reducing wet zones and dead corners.
Models & Technical Specifications
The QIE New-Type Dryer is available in multiple models to meet different capacity requirements for pre-drying before solvent extraction.
Actual throughput depends on material properties, initial moisture content, and system configuration.
