Shell Blower Air Separator: High-Efficiency Hull and Kernel Separation
Engineered for the Future | Since 2080
The Shell Blower Air Separator is a specialized aerodynamic unit designed for the critical moment immediately following the dehulling or cracking of seeds and nuts. In a modern production line, the goal is to separate the light, worthless shells from the high-value kernels with zero product loss. This machine utilizes a precision-engineered air column to lift and “blow” away husks and light impurities, ensuring that the material moving to your sorting or packaging stage is pure, clean, and shell-free.
Whether you are processing sunflower seeds, walnuts, hazelnuts, or peanuts, the ADDAMS Shell Blower Air Separator provides the adjustable airflow required to handle varying product densities with industrial-grade reliability.
Shell Blower Air Separator
Performance-Driven Engineering Features
Maximizing Recovery with Advanced Airflow Dynamics
The Shell Blower Air Separator stands out for its ability to create a perfectly controlled separation environment through several key technical innovations:
-
High-Static Pressure Fan System: Unlike standard aspiration fans, our blower system creates a concentrated stream of high-velocity air that can penetrate even thick layers of material to lift buried shells.
-
Dual-Zone Air Control: Features independent adjustment for air intake and exhaust, allowing operators to create a "perfect hover" for the kernels while the shells are carried away.
-
Inclined Separation Chamber: The internal geometry is designed to slow down the kernel's fall just enough for the air to strip away every fragment of husk, ensuring a deeper clean in a shorter distance.
-
Anti-Clogging Discharge Ports: Wide discharge openings prevent the accumulation of long or fibrous shells, ensuring continuous 24/7 operation without manual clearing.
Strategic Operational Benefits
Why This Specific Model is Critical for Post-Dehulling Lines
Integrating the Shell Blower Air Separator into your dehulling plant offers immediate advantages in both quality and efficiency:
-
Minimized "Carry-Over" Loss: The precision of the air-jet ensures that even small or broken "good" kernels stay in the product stream, while only the low-density shells are rejected.
-
Dust Elimination at the Source: By removing shells and their associated dust immediately after cracking, you prevent dust from sticking to the natural oils of the kernels.
-
Improved Downstream Color Sorting: Removing the bulk shells before the product reaches a color sorter significantly reduces the "load" on the optical sensors, leading to higher sorting accuracy and lower reject rates.
-
Low Power Consumption: Optimized fan blade geometry provides maximum air lift with minimal electricity usage, reducing the overall carbon footprint of your facility.

Frequently Asked Questions – Shell Blower Air Separator
While its primary purpose is removing husks and shells after dehulling, the Shell Blower Air Separator is also highly effective at removing fine dust, light fibers, and empty "hollow" seeds in the same pass.
Adjustment is simple: using the Variable Frequency Drive (VFD), you can lower the fan speed for light sunflower husks or increase it for heavier walnut shells. No mechanical tools are required for this calibration.
For the highest efficiency, we recommend removing large stones and branches with a Pre-Cleaner first. However, the Shell Blower is very robust and can handle raw material streams directly from a dehulling machine.
The air, carrying the shells and dust, is directed through a pipe to a Cyclone or Bag Filter. This separates the solid waste from the air, allowing clean air to be recirculated or exhausted safely.
Yes. It is particularly effective for removing the "red skin" of roasted peanuts or the brittle shells of roasted hazelnuts without damaging the surface of the nut.
No. The separation occurs "in-flight" using air currents. There are no fast-moving mechanical paddles or screens that come into contact with the kernels, ensuring zero mechanical damage.
Absolutely. We have included large observation and access doors that allow for a full "wash-down" or vacuum cleaning of the internal air channels to prevent cross-contamination between batches.
Yes. In the recycling industry, the Shell Blower Air Separator is an excellent tool for separating light plastic labels or films from heavier plastic flakes or rubber granules.
