Sunflower Seed Cleaning Machine

Sunflower Seed Cleaning Machine

Hebei Julite Sorting Technology Co., Ltd. offers its Sunflower Seed Cleaning Machine, carefully designed to address the challenges posed by variable seed sizes, hull fragments, and dust. This machine delivers precise cleaning and grading to prepare seeds for snack roasting, oil pressing, and bird‑feed applications.

Machine Workflow

1. Pre‑Cleaning Vibratory Screen
   A robust vibrating screen removes large debris—stalk parts, stones, and clumps—while retaining whole seeds. Screen parameters are customized for kernel size variations across sunflower varieties.

2. Aspirator and Dust Extraction
   Controlled airflow lifts fine dust, loose hull pieces, and lightweight chaff from the seed stream. Air volume and deck inclination are adjustable to handle seasonal variations in field‑dry sunflower seeds.

3. Destoning Unit
   A density‑based destoner separates stones and heavy impurities by calibrating air pressure and vibration. This module protects delicate optical sensors and downstream equipment.

4. Magnetic Separator
   To maintain equipment integrity, a powerful magnetic head captures any metallic contaminants before the seed enters finer cleaning stages.

5. Precision Sieving
   Multi‑deck screening sorts seeds into distinct size fractions. Uniform seed size ensures even roasting, pressing, or packaging performance.

6. Optional Optical Sorting
   An optical module can be added to detect discolored, insect‑damaged, or deformed seeds. High‑resolution cameras and timed air jets eject these rejects with accuracy.

Design Advantages

• Modular Construction: Core cleaning units can be supplemented with destoning, magnetic, and optical modules according to processor needs.

• Hygienic Standards: All seed‑contact parts are constructed from stainless steel with hygienic finish; smooth surfaces and easy‑open panels facilitate sanitation.

• Operator Interface: An HMI touch panel provides real‑time display of throughput, reject rates, and airflow pressures. Preset cleaning programs accelerate changeovers.

• Maintenance Accessibility: Slide‑out decks and quick‑release fasteners allow rapid access for cleaning and screen changes without specialized tools.

Benefits in Operation

• High Purity Output: Multi‑stage cleaning reduces foreign matter and dust to levels suitable for direct oil pressing or snack production.

• Limited Kernel Damage: Gentle vibratory and airflow settings preserve seed integrity, reducing breakage and maintaining kernel viability for germination if required.

• Energy‑Efficient Performance: Variable drives on blowers and vibrators ensure power consumption aligns with processing load.

• Capacity Options: Models range from 1 t/h for small operations up to 12 t/h for larger processors.
