Seed Cleaner and Grader China Factory

Seed Cleaner and Grader

Hebei Julite Sorting Technology Co., Ltd. introduces its Seed Cleaner and Grader, a versatile solution capable of processing a wide variety of seeds—such as wheat, barley, corn, and legumes—by combining impurity removal with precise size and weight grading in a single unit.

Integrated Cleaning and Grading Process

1. Coarse Screening: Incoming seed enters a vibrating screen to remove oversized debris (stalks, large stones) and undersized impurities (dust, fine chaff).

2. Aspirator Module: Controlled air currents lift lightweight particles while the cleaned seeds descend, improving overall purity.

3. Destoner Section: Leveraging air and vibration, this stage ejects heavy mineral fragments that match seed size but differ in density.

4. Magnetic Separation: A magnetic filter captures metal contaminants before the seed proceeds.

5. Precision Grading: Seed passes over a series of adjustable sieves or zig‑zag graders. Multi‑deck sieves classify kernels by diameter, while zig‑zag motion separates seed lots according to weight and shape, delivering uniform batches ideal for planting or end‑use processing.

Design Highlights

• Modular Configuration: Cleaning and grading modules can be arranged inline or bypassed to suit specific seed types and purity requirements.

• Control System: A centralized PLC and touchscreen HMI allow operators to monitor reject rates, throughput, and machine health. Pre‑configured recipes simplify changeovers.

• Robust Construction: Frame and non‑contact components use high‑strength steel, while contact surfaces employ smooth‑finish stainless steel to resist corrosion and facilitate cleaning.

• Easy Maintenance: Tool‑less access panels, slide‑out sieve decks, and centralized grease fittings simplify routine servicing.

Advantages in Operation

• High Throughput with Precision: Combining cleaning and grading in one machine reduces floor space requirements while maintaining capacity up to 15 t/h, depending on seed type.

• Consistent Seed Lots: Accurate size and weight separation support uniform planting depth and germination rates for seed producers, as well as consistent input quality for food processors.

• Energy‑Efficient Drives: Variable‑frequency motors adjust power draw based on load, minimizing energy usage during lighter runs.
