The commonly used machines for cleaning wheat include air screen cleaners, gravity cleaners, grading screens, stone removers, etc. Different machines can be used alone or in combination to achieve efficient cleaning for different types of impurities.
1. air screen cleaners (Basic Core Equipment)
This is the most basic and widely used equipment for wheat cleaning, primarily addressing both light and heavy debris.
Targets: Light impurities such as dust, chaff, and shredded grains, as well as large impurities such as straw and clods of earth, and small impurities such as sand and gravel.
Working Principle: A combination of wind separation and screening. Wind separation uses wind to separate light impurities, while screening uses sieves of varying mesh sizes to separate wheat from impurities by size.
2. Gravity Cleaner (Key Equipment for Addressing Gravity Impurities)
This type of equipment is required when wheat contains impurities of similar size but different specific gravity (such as stones or mud). It is an important supplement to the wind-screen cleaner.
Targets: Stones and metal lumps of similar size but greater specific gravity, or insect-damaged or moldy grains of lower specific gravity. Working Principle: By utilizing the difference in specific gravity between wheat and impurities, on the inclined and vibrating screen surface, combined with the action of airflow, materials with different specific gravities are separated into layers, ultimately achieving separation.
3. Air Screening and Gravity Cleaner (High-Efficiency Integrated Equipment)
This type of equipment integrates multiple cleaning functions, including air screening and gravity separation, to remove multiple types of impurities simultaneously, achieving higher efficiency.
Cleaning Targets: Simultaneously removes light impurities, large and small impurities, and impurities of specific gravity. Some models also remove broken grains and those with pests and diseases.
Working Principle: Integrates air separation, screening, and gravity separation. Some models also incorporate magnetic separation (to remove metallic impurities) and color sorting (to remove off-color grains), forming a multi-stage cleaning process.
Other Auxiliary Cleaning Equipment
In addition to the core cleaning machine, the following auxiliary equipment is also used in some scenarios to further enhance cleaning efficiency:
Magnetic Separator: Uses magnets to attract metal impurities such as nails and wire in the wheat, preventing subsequent equipment damage.
Color Sorter: Utilizes optical principles to identify and remove moldy, diseased, and off-color kernels. It is primarily used for cleaning high-quality wheat or seeds.
Vibrating Classifier: After cleaning, it grades the wheat by particle size, rather than simply removing impurities. It is suitable for processing scenarios where finer grain size is required.
