Peanut Seed Coating and Packing Machinery Line

Peanut Seed Coating and Packing Machinery Line

Shijiazhuang Xinlu Technology Co., Ltd. provides an automated peanut seed coating and packing machinery line that applies protective or flavoring coatings to kernels and packages them in accurately weighed bags. This integrated solution is suitable for snack producers, flavor houses, and value‑added peanut product manufacturers.

Line Process Description

1. Pre‑Treatment Drying

• Graded peanuts are conveyed into a forced‑air dryer, reducing moisture content to an optimal level for coating adhesion.

2. Coating Drum

• A rotating drum equipped with adjustable paddles and a metered spray system applies liquid or powder coatings—such as seasonings, flavor oils, or nutritional additives—uniformly to the kernel surfaces.

3. Post‑Coating Drying & Cooling

• Coated peanuts pass through a multi‑zone drying tunnel where heated air cures the coating, followed by a cooling conveyor that returns seed to ambient temperature.

4. Weighing & Bagging

• An inline electronic scale dispenses exact weights (±0.2 %) into pre‑formed bags. A form‑fill‑seal machine then seals, codes, and ejects the final packages.

5. Quality Inspection

• Integrated metal detectors and weight-check systems ensure each bag meets safety and weight specifications before discharge.

Key Technical Features

• Precision Dosing Pumps: Peristaltic pumps deliver coating solutions at rates from 0.1 to 10 mL per kg of peanuts.

• Recipe Management: PLC stores multiple coating formulations and packaging weights for rapid product changeovers.

• Dust‑Proof Enclosures: Sealed coating drum and drying tunnel minimize powder escape and maintain a clean work environment.

• High-Speed Packaging: The bagging line can achieve up to 40 bags per minute, depending on bag size and fill weight.

Operational Advantages

• Uniform Coating Quality: Even distribution of flavor or protective agents enhances product consistency.

• Reduced Labor Costs: Automated weighing and bagging streamline final packaging tasks.

• Traceability and Compliance: Automatic batch coding and weight verification support quality control and regulatory requirements.

• Compact Footprint: Inline layout conserves floor space in production facilities.
