Air Screen Cleaner Machine for Grain & Seed Processing

During processing of grain, seeds, nuts and plastic pellets, raw materials are commonly mixed with dust, empty shells, shrivelled grains and debris. These impurities downgrade final product quality and increase wear on downstream machines for color sorting, packaging and pelletizing.

Manual sorting or single‑screen cleaning brings low throughput and high labor costs, with poor removal of light contaminants. Our air screen cleaner reaches 1‑3 t/h processing capacity. It combines vibrating screening and dual‑suction air winnowing to finish impurity removal, grading, and dust collection in one unit.

It separates dust, hollow kernels and fiber residues, and classifies materials by particle size. Available in single‑layer, double‑layer, multi‑function and anti‑blinding pressure‑net models. It works well for grains, beans, nuts and plastic pellets, serving as essential pre‑processing equipment for modern processing plants.

Working principle of the air screen grain cleaning machine

The machine consists of a vibrating screen deck, replaceable screens, dual-suction air dust removal system and drive motor. It processes materials via vibrating screening and air winnowing:

1. Vibrating Screening & Grading: Raw materials enter the screen deck, graded by particle size via vibration and different screens. Fine impurities fall and are discharged; qualified materials and large particles are discharged separately.
2. Dual-suction Air Winnowing & Impurity Removal: Dual-suction fans generate adjustable airflow to suck away light impurities like dust and empty shells, discharging floating debris and improving cleanliness.
3. Pre-processing Function: Uniform and clean materials can directly enter subsequent processes, reducing equipment wear and improving production efficiency.

Core functions

• Impurity Removal: Dual-suction air system removes light impurities and debris to improve raw material cleanliness
• Material Grading: Replace screens to achieve multi-particle-size classification for multi-variety processing
• Workshop Dust Removal: Closed air suction reduces dust diffusion and improves working environment
• Pre-processing: Provides high-quality raw materials for color sorters to improve accuracy and reduce wear
• Foreign Matter Removal: Separates broken materials, skins and part of sand and stones to ensure finished product quality

Main model parameters: how to choose according to capacity?

We provide various standard models, including single-layer, double-layer, multi-functional, and pressure-net grading types, with processing capacities ranging from 1 to 3 tons per hour. Meeting the needs of small and medium-sized processing plants to large-scale production lines.

Model Differentiation: Single-layer models are suitable for simple impurity removal. Double-layer models can separate 3-4 material specifications simultaneously. Pressure-net models are designed for oily and easily clogging materials to avoid screen clogging and capacity reduction.

Quality & efficiency improvement for subsequent processes

Insufficient pre-cleaning will increase the load of color sorters, leading to fast consumable wear and poor sorting effect. After pre-treatment by the air screen cleaner:

• Clean and uniform materials improve color sorting accuracy and reduce defective rate
• Less impurities in roasting process optimize finished product appearance
• Reduce wear of subsequent equipment and extend service life
• Save labor costs for manual sorting

Key considerations for selecting an air screen cleaner

• Processing Capacity: Select model based on actual output with reserved margin, avoiding long-term full-load operation
• Material Type: Anti-clogging pressure-net model for oily and sticky materials; stainless steel contact parts for food processing
• Grading Demand: Single-layer model for simple impurity removal; double-layer screen model for multi-specification grading
• Workshop Conditions: Confirm site size, voltage, mobility and assembly line connection requirements
• Impurity Type: Dual-suction configuration for more light impurities; pre-cleaning equipment for large sand and stones
