Product Details

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.

Feed moisture range: 25% – 58%
Final moisture after drying: ≤13% (depending on material and operating parameters)

Final model selection and configuration should be determined based on raw material characteristics, moisture content, and target extraction capacity.

Why Choose QIE?
