The rapeseed air-screen cleaner is a device used for cleaning and removing impurities from rapeseed. It combines the functions of air separation and screening, effectively removing impurities and improving rapeseed quality. Here is a detailed introduction:
Structural Components:
Hopper: Used to store the rapeseed to be screened, serving both storage and uniform feeding functions.
Frame: Provides support for the entire machine, typically made of sturdy metal materials. Some frames are equipped with wheels for easy movement.
Transmission Mechanism: Connects the motor and various working parts, enabling the fan, screen, etc., to operate normally.
Fan: The key component of the air separation function, generating airflow to separate light impurities from the rapeseed.
Air Duct: Guides the airflow, allowing light impurities to be carried away along the airflow direction, achieving air separation.
Screen: Available in various sizes, screening according to the size differences between rapeseed and impurity particles. Typically made of wear-resistant materials such as stainless steel.
Working Principle: The rapeseed air-screen cleaner primarily operates based on the principles of air separation and screening. After the material enters the feed hopper, it falls evenly onto the upper screen. The airflow generated by the blower carries away light impurities such as straw fragments and shriveled grains, while the heavier rapeseed remains on the screen surface. Simultaneously, screens with different apertures sift the rapeseed; larger stones and clods of soil are blocked during the initial screening, while smaller impurities are removed in the subsequent fine screening process.
Performance Characteristics:
High Screening Efficiency: Generally employing a multi-layer screen design, such as a three-layer screen, the screening rate for impurities such as dust, debris, damaged seeds, and small stones in rapeseed can reach over 95%.
Easy Operation: The equipment has a relatively simple structure and small footprint. After connecting to power, it can operate normally by adjusting components such as the bottom stopper plate of the hopper. Cleaning is convenient and effectively prevents mixing.
Wide Application Range: Not only suitable for cleaning rapeseed, but also for the selection, grading, and impurity removal of seeds from various crops such as wheat, rice, corn, and soybeans.
