Rotary Dryer for Peanut Shell
Industrial Rotary Dryer for Peanut Shell Drying
Peanut shells are a common agricultural biomass material generated from peanut processing industries. Due to their high moisture content after collection, peanut shells usually require an efficient drying process before further utilization, such as biomass pellet production, briquette manufacturing, boiler fuel, animal bedding, or biochar production.
Our Rotary Dryer for Peanut Shell is specially designed for continuous drying of agricultural biomass materials. It can effectively reduce moisture content, improve combustion efficiency, and provide stable raw material conditions for downstream processing.
The drying system adopts a rotary drum structure with hot air circulation. Through continuous lifting, tumbling, and heat exchange inside the drum, wet peanut shells can achieve uniform drying with high efficiency and low energy consumption.
We provide customized peanut shell drying solutions according to:
- Raw material moisture content
- Required final moisture
- Processing capacity
- Available heat source

Why Peanut Shells Need Drying Before Processing?
Peanut shells normally contain moisture after collection and storage. High moisture content can cause several problems:
1. Lower Fuel Efficiency
Wet peanut shells require more energy during combustion or carbonization because additional heat is consumed for water evaporation.
2. Difficult Pellet and Briquette Production
For biomass pellet or briquette production, excessive moisture affects:
- Material compression
- Product strength
- Production stability
3. Storage Problems
High moisture biomass is more likely to:
- Develop mold
- Reduce storage time
- Affect product quality
4. Unstable Carbonization Process
For peanut shell biochar production, proper drying helps achieve:
- Stable pyrolysis temperature
- Higher carbonization efficiency
- Better charcoal quality
Therefore, an industrial peanut shell drying machine is an important part of biomass processing systems.
Working Principle of Rotary Dryer for Peanut Shell
The peanut shell rotary dryer mainly consists of:
- Feeding system
- Rotary drum
- Hot air furnace
- Dust collection system
- Discharge system
- Control system
The working process:
Step 1: Feeding
Wet peanut shells are continuously fed into the rotary drum through a conveyor or feeding device.
Step 2: Heat Exchange
Inside the rotating drum, lifting plates continuously lift and scatter the peanut shells.
The biomass material contacts with hot air repeatedly, allowing moisture to evaporate quickly.
Step 3: Moisture Removal
The humid air is discharged through the exhaust system after passing through dust removal equipment.
Step 4: Dry Material Discharge
The dried peanut shells are collected at the outlet and can be sent to:
- Pellet machine
- Briquette machine
- Carbonization furnace
- Storage system
