Dakota Blower
Efficient air-based cleaning system designed to remove light impurities such as dust, husk, and chaff from seeds and grains using controlled airflow.
What is Dakota Blower?
The Dakota Seed Blower is an essential analytical device utilized in agricultural testing laboratories to classify seed samples based strictly on terminal velocity and aerodynamic properties.
The system operates by channeling a meticulously regulated column of air upwards through a transparent vertical tube containing the raw seed sample. Lighter impurities—such as dust, chaff, weed seeds, and underdeveloped or empty spikelets—are lifted by the controlled airstream and trapped in upper collection baffles, while the heavier, viable pure seeds remain secured at the base.
This equipment is critical for commercial seed conditioning and quality assurance; it replaces inconsistent manual winnowing with mathematically repeatable pneumatic separation, allowing lab technicians to establish the precise physical purity percentages required for official seed certification and high-value agricultural trading.
Common Applications
Seed Testing & Certification Labs
For conducting official physical purity tests and establishing pure live seed (PLS) metrics for regulatory compliance.
Commercial Seed Conditioning Plants
Used to precisely calibrate large-scale gravity separators and air-screen cleaners by establishing exact pneumatic separation thresholds in the lab.
Agricultural Botany & Research
Essential for safely cleaning small, delicate experimental seed lots where mechanical screening could damage the kernels.
Forestry & Native Seed Processing
Effectively isolating extremely light, aerodynamically irregular native grass and tree seeds from inert organic forestry debris.
