TAOBO Air screen cleaner with gravity separator is a multifunctional processing unit for specialty grains that integrates dual-stage air separation, multi-layer vibrating grading screens, a gravity separation table, and an enclosed dust removal system. Capable of simultaneously performing dust removal, impurity sorting (by size), removal of moldy or shriveled kernels, and light-duty destoning, it eliminates the need for a complex assembly of multiple standalone machines. Specifically designed to handle raw grains with high impurity levels—common in Africa—it offers flexible switching between crops such as sesame, pigeon peas, red kidney beans, and soybeans. It serves as the core pre-cleaningequipment for specialty grain export processing plants in Mozambique.

Key Features of the Air-Screen Gravity Cleaner

 Versatile multi-purpose operation suited for local dual-crop processing

Most traders in Mozambique source sesame, soybeans, and pigeon peas for export. By simply swapping screens and making minor adjustments to fan airflow and the gravity table's tilt angle, the machine can quickly switch between processing different raw materials. This eliminates the need to purchase multiple standalone cleaning units, thereby saving factory floor space and reducing equipment investment costs.

 Handles local high-impurity "red soil" crops, achieving export-grade purity

A dual-air separation system powerfully removes fine red soil particles; grading screens separate soil clumps and debris of various sizes; and a gravity table eliminates moldy grains, stones, and grit. The final product achieves 99.5% purity, fully meeting the quality inspection standards of buyers from India, China, and the Middle East, while preventing price markdowns or shipment rejections.

 Eco-friendly enclosed dust removal, ideal for basic African factory setups

Equipped with a comprehensive negative-pressure cyclone dust removal system, the machine prevents dust clouds during the processing of red-soil-laden crops, ensuring compliance with food processing hygiene standards. The reinforced, sandblasted frame offers superior wear and corrosion resistance, enabling continuous 24-hour operation even in harsh tropical conditions characterized by high humidity and sandy soil.

Operational Efficiency of the Air-Screen Gravity Separator

✅  Stable Hourly Processing Capacity

Sesame: 10–15 tons/hour. Despite the fine nature of sesame seeds and the presence of significant red soil and fine sand, the dual air-screen system ensures continuous dust removal without clogging, maintaining a steady, unvarying flow rate.

Pigeon Peas / Soybeans: 15–20 tons/hour. Featuring widened screen boxes and gravity separation decks, the machine ensures uniform material spreading for large-grained crops, preventing accumulation or blockages; this meets the demands of large-scale processing plants for high-volume, continuous operations.

✅  Integrated Design: Superior Efficiency Compared to Piecemeal Solutions

This machine integrates three functions—dual air separation, multi-layer grading screens, and a gravity separation deck—into a single unit. A single pass processes the raw material through four stages: dust removal, separation of large and small impurities, removal of moldy or shriveled seeds, and light-duty destoning. This eliminates the need for secondary material transfer or re-screening.

If you require processing solutions for various grains and legumes—such as sesame seeds, pigeon peas, red kidney beans, or chickpeas—or have specific requirements regarding facility dimensions, hourly throughput, raw material impurity levels, or export quality standards, please feel free to contact us to develop a customized cleaning plan. With extensive practical experience serving grain processing plants across Africa and Europe, we invite you to share details such as the type of produce, hourly output, and facility dimensions; we will then tailor a comprehensive cleaning and sorting solution specifically designed for your local export processing needs.
