Product Introduction

The 25kg Nuts Packaging Machine is a fully automated open-mouth bagging system engineered for high-speed, precision packaging of nuts (e.g., almonds, peanuts, cashews) into 25–50kg woven polypropylene bags. Designed for food-grade compliance, it integrates advanced weighing, filling, and sealing technologies to achieve ±0.2% weight accuracy at speeds of 200–300 bags/hour.Its modular construction allows customization for bulk handling in nut processing plants, ensuring hygiene and operational efficiency.

Technical Specifications

Core Parameters

Bag Capacity: 25–50kg (expandable to 1000kg jumbo bags with optional palletizing modules).

Weighing System: Load-cell technology with auto-calibration (10g sensitivity; 98%合格率).

Power Requirements: 380V, 8kW (energy-saving mode reduces consumption by 15%).

Operating Pressure: 0.6–0.8MPa pneumatic system (20m³/h air consumption).

Dimensions: 2400(L)×3800(W)×4200(H)mm (compact footprint for factory floors).

Material Contact Parts: SUS304 stainless steel (FDA-approved for food safety).

Control Interface: 10" touchscreen with PLC (supports multi-language: English/Spanish/Russian).

Key Features

Dual-Stage Filling: Fast-fill (90% capacity) + precision mode (10% top-up) to minimize spillage.

Dust Control: Integrated 3000m³/hr extraction system with HEPA filters.

Bag Handling: Pneumatic clamps adjust to bag sizes (530–750mm length; 250–380mm width).

Sealing Options: Heat-sealing (180–200°C) or stitching (industrial-grade thread).

Smart Diagnostics: Real-time fault alerts via touchscreen (e.g., sensor drift, jam detection).

Applications

Nut Processing Facilities: Packing roasted/salted almonds, peanuts, or mixed nuts.

Export Packaging: Compliant with international food safety standards (HACCP, ISO 22000).

Bulk Retail: Automated bagging for wholesale distributors (customizable branding labels).

Operating Guidelines

Setup & Calibration

Installation:

Level the machine on reinforced concrete;connect to 380V power and 0.6MPa air supply.

Mount the bag clamp and adjust tension to prevent slippage (test with empty bags).

Calibration:

Use 25kg test weights to calibrate load cells;set tolerance thresholds (±50g).

Production Workflow

Automatic Mode:

Operator places open-mouth bag → Infrared sensor triggers filling → Dual augers dispense nuts.

After the weight meets the standard → Auto-sealing → Conveyor transfers to palletizer (optional).

Manual Override:

Emergency stop button; adjust fill speed via PLC during low-moisture nut variants.

Maintenance Protocol

• Daily: Clean hopper and augers with food-safe sanitizers;inspect seal integrity.

• Weekly: Lubricate bearings (NSF H1 grease);replace dust filters if airflow drops below 80%.

• Monthly: Recalibrate load cells;check pneumatic hoses for leaks.

Troubleshooting & FAQs

Common Issues

Inconsistent Weight:

Cause: Nut fragments obstructing auger or sensor misalignment.

Solution: Clear hopper;recalibrate via touchscreen "Auto-Zero" function.

Bag Misalignment:

Cause: Clamp pressure too low or conveyor belt misadjusted.

Solution: Increase clamp pressure to 0.5MPa;realign guide rails.

Seal Failure:

Cause: Contaminated sealing strip or low temperature.

Solution: Clean strips with alcohol; reset heat-sealer to 190°C.

FAQ

Q1: Can it handle oily nuts (e.g., walnuts)?

Yes, optional Teflon-coated augers prevent sticking;nitrogen flushing reduces oxidation.

Q2: How to integrate with existing ERP systems?

Ethernet/RS485 ports enable real-time data export (bag counts, weight logs).

Q3: What’s the lifespan of critical components?

Augers: 7+ years (hardened steel).

Sensors: 1 million cycles (IP67-rated).

Q4: Is the machine compatible with valve bags?

Yes, with optional valve bag adapter kits (provide inner diameter specs for quote).

Support & Warranty

Warranty: 2 years on electrical components;lifetime frame support.

Training: On-site operator training (includes allergen cross-contamination protocols).

Spare Parts: Global 48-hour delivery for consumables (seals, filters, augers).
