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.

2026 gravity separator utilizes differences in material specific gravity to perform sorting. It is specifically designed to remove impurities and inferior-quality grains that are similar in size to the target seeds—particles that are otherwise difficult to separate using conventional air-screen or vibrating-screen cleaners. It serves as a core piece of precision-sorting equipment in processing lines for grains, sesame seeds, and legumes.

Sesame seeds are extremely small (approximately 1.5–2 mm in diameter) and flat-oval in shape, with a smooth surface, high oil content, and relatively low specific gravity. These physical characteristics present unique challenges for cleaning: while light impurities—such as stalks, husks, dust, and shriveled or empty seeds—can be removed via air classification (aspiration), and oversized or undersized debris can be intercepted through screening, certain contaminants pose a greater difficulty. Specifically, stones, sand, clods of soil, and metal fragments—which are similar in size to sesame seeds but have a significantly higher specific gravity—cannot be effectively separated by either air classification (as they are too heavy to be moved by airflow) or screening (as they pass through or are retained alongside the seeds).

Pakistan is a significant global producer and exporter of sesame seeds, ranking as one of the few oilseed crops for which the country maintains a net export position. According to data from Pakistan’s Ministry of National Food Security and Research, the area under sesame cultivation expanded substantially from approximately 259,900 hectares in the 2022/23 crop year to about 399,800 hectares in 2023/24—an increase of 53%. Production reached approximately 301,200 tonnes, a sharp year-on-year rise of 97.7%. For the 2024/25 crop year, production is projected to climb further to approximately 440,000 tonnes (a 44.7% year-on-year increase), with the harvested area—as recorded by FAOSTAT—exceeding 700,000 hectares. The primary production regions are concentrated in Punjab province (cultivated during the *Kharif* monsoon season, covering approximately 1.76 million acres in 2024) and parts of Sindh province. In recent years, technical cooperation between Pakistan and China, alongside the adoption of contract farming, has led to significant improvements in both crop yields and the level of commercialization.
