The Multi-functional Double-suction Screening Machine is an efficient sorting and cleaning solution for processing various granular and pellet materials. By combining vibrating screen separation technology with dual-suction air classification, it effectively removes dust, light impurities, empty shells, broken particles, and oversized materials while accurately separating products according to different sizes.
With a capacity of 1-3 t/h, this machine is available in four different models to meet the processing requirements of different customers. It is suitable for a wide range of granular materials, including pistachios, peanuts, sunflower seeds, melon seeds, beans, cereals, corn kernels, rapeseed, sesame, plastic pellets (PP/PE/ABS), rubber granules, and other similar materials.
The Double-suction Screening Machine is widely used in nut processing factories, seed processing plants, grain storage facilities, food production enterprises, and plastic recycling industries. Welcome to choose the suitable model of our Double-suction Screening Machine for your processing business!
How Does the Double-suction Screening Machine Work?
Material is evenly fed onto a vibrating screen deck. The combination of mechanical vibration and adjustable screen apertures separates particles by size — fines fall through the mesh, while oversize and qualified fractions are discharged separately.
Meanwhile, two powerful stainless-steel suction fans generate upward airflow across the material stream. This dual-suction system removes:
- Light impurities — dust, chaff, empty shells, hull fragments.
- Low-density contaminants — shriveled seeds, moldy grains, foreign fibers.
- Surface debris — soil, small leaves, plastic film residue.
The result is a cleaner, better-graded raw material that is ready for color sorting, roasting, packaging, or extrusion.
Core functions
- تنظيف: Uses a dual air suction system to efficiently remove dust, light impurities, and foreign materials from raw materials, improving overall product quality.
- Grading: Separates materials into different size grades through interchangeable screening meshes, ensuring accurate and consistent classification.
- Dedusting: Equipped with an integrated fan system to reduce airborne dust, creating a cleaner and safer working environment.
- Pre-color Sorting Preparation: Provides clean and uniform raw materials for optical color sorters, improving sorting accuracy and processing efficiency.
- Impurity Removal: Effectively removes unwanted materials such as empty shells, broken kernels, stones, and metal particles to ensure higher purity of finished products.

Key Features & Advantages
- Dual-suction air cleaning system — Two strategically placed suction fans provide more thorough removal of light impurities than single-fan designs.
- Interchangeable screen decks — Quick-change mesh sizes allow precise grading for nuts, seeds, grains, or plastic pellets.
- Single-layer & double-layer options — Choose the right number of decks based on the number of fractions required.
- Pressure-net screen technology — Prevents mesh blinding and maintains stable output, even with oily or sticky materials.
- Full stainless-steel construction available — 304/201 stainless steel options ensure food-grade hygiene and corrosion resistance.
- Low noise & low energy consumption — High-efficiency motors reduce operating costs.
- Mobile frame with casters — Easy to move, install, and integrate into existing processing lines.
- Large inspection windows — Allow operators to monitor material flow and screen condition in real time.
