Smart Salt Packaging Machine Line Solution High Speed VFFS and Open Mouth Bagging
Turnkey integration centered on the packaging machine for sea salt, rock salt, and table salt, focused on high speed, hygiene, corrosion resistance, easy changeover, and stable operation.
Core Module: Vertical VFFS Salt Packaging Machine
For 50 g to 2 kg pouches using cup dosing or multihead weighers. Supports pillow, flat bottom, and stand up formats. Choose continuous or intermittent motion by throughput and film. Contact parts can be specified for corrosion resistance to handle salty environments.
Vertical form fill seal machine with fast changeover and multiple bag styles
- High speed bag forming with stable sealing to increase hourly output
- HMI recipe management to reduce changeover downtime
- Easy links to upstream screening and downstream checkweighing and metal detection
Product Scope and Formats
- Products: sea salt, rock salt, refined salt, low sodium salt, blended seasoning salt
- Sizes: 50 g to 2 kg pouches and 5 kg to 25 kg medium/heavy bags
- Bag styles: pillow bag, flat bottom bag, side seal, stand up bag, open mouth pre-made bag
Core Module: Open Mouth Automatic Bagging System
For 5 kg to 25 kg formats with automatic bag pick, dosing, bag mouth shaping, de-aeration, and sealing. Compatible with paper, plastic, and PE heat seal materials. Can connect to robotic palletizing and wrapping for a complete line.
- Fast change between multiple bag sizes and stacking patterns
- Heat sealing or stitching with neat bag mouth finish
- Linked dust extraction and weighing buffer to keep the line clean
Open mouth automatic bagger with weighing and sealing modules
Standard Process and Control Points
- Pretreatment: salt screening and decontamination (optional de-ironing)
- Dosing by cup, multihead weigher, or screw based on granularity and accuracy
- Filling: small pouches on VFFS, medium/heavy bags on open mouth bagger
- Sealing: pouches by heat or ultrasonic, heavy bags by heat or stitching with folded edges
- Inline coding: batch and date labels or thermal transfer
- Inspection: dynamic checkweighing and metal detection with combined rejection
- Case packing and palletizing with stretch wrap or over bag for moisture protection
- Data and traceability: batch barcode records connectable to MES or WMS
Quality Control and Traceability
Combine checkweighing and metal detection to intercept underweight, overweight, and foreign bodies. Bind inspection results to batch data to generate traceable reports and improve compliance.
Compact combination unit for weight and metal inspection
- Dynamic weighing for common net weight ranges
- Multi-frequency detection for stainless and non-ferrous metals
- Dual rejects separating weight failures and foreign body failures
Capacity and Configuration
- High speed small pouch line: 60 to 120 bags per minute with continuous VFFS and multihead weighers
- Medium/heavy bag line: 10 to 20 bags per minute with open mouth or FFS bagging
- Unified HMI recipes for fast switching from 50 g to 25 kg
Hygiene and Corrosion Resistance
- 304 or 316L contact materials, sealed bearings, and enclosures for salty environments
- Dust hoods at drop and stitching points connected to a central duct
- Tool-free hopper and guide removal, optional IP65 to IP69K equipment
Implementation and Services
- Line layout and interface lists with drawings and I/O tables
- FAT and SAT, operator training, spare parts lists, and maintenance plan
- Remote support, periodic inspections, and KPI reporting templates
