Overall Approach
The line is organized around process nodes and quality control A typical path is raw salt buffering and screening dosing and feeding forming and filling bag mouth shaping and sealing inline inspection coding and labeling end of line case packing and palletizing data capture and traceability.
- Covers 50 g to 25 kg formats and multiple bag materials
- One touch recipe management to reduce changeover time
- Salt dust control and anti corrosion measures for maintainability
Core Equipment Vertical VFFS Salt Packaging Machine
For 50 g to 2 kg pouches Supports pillow flat bottom and stand up bags Choose continuous or intermittent motion by capacity Dosing by cup or multihead weigher Contact parts in 304 or 316L with sealed construction to handle salty environments.
- Short film path and strong sealing increase hourly output
- HMI recipes and quick change forming sets for multiple SKUs
- Optional corrosion resistant configuration for salty washdown
Products and Bag Styles
- Products sea salt rock salt refined salt iodized salt low sodium salt seasoning blends
- Bag styles pillow flat bottom side seal stand up open mouth pre made
- Materials laminate paper plastic PE with moisture barrier options
Core Equipment Open Mouth Automatic Bagging System
For 5 kg to 25 kg formats with automatic bag pick accurate filling bag mouth shaping de aeration and heat sealing or stitching Can connect to robotic palletizing and stretch wrapping to deliver a complete line.
- Fast change between bag sizes compatible with PE and paper plastic
- Linked weighing and conveying to reduce drop height and dust
- Clear maintenance access to shorten downtime
Process and Control Points
- Pretreatment 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 heat or ultrasonic for pouches heat or stitching with folded edges for heavy bags
- 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 and records connectable to MES or WMS
Inline Quality Control and Traceability
Checkweighing and metal detection in combination intercept underweight overweight and foreign bodies Results are linked to batch data to generate traceable reports and improve compliance.
- Dynamic weighing across common net weight ranges
- Multi frequency metal detection for stainless and non ferrous metals
- Dual reject paths to separate weight and foreign body failures
Layout and Capacity Recommendations
- 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
- Straight or L shaped layouts with centralized dust extraction
Hygiene and Corrosion Resistant Design
- 304 or 316L contact parts sealed bearings and enclosures for salty environments
- Tool free cleaning on hoppers and guides optional IP65 to IP69K equipment
- Dust hoods at drop and stitching points optimized drop height to reduce dust
Implementation and Services
- Line layout and interface lists with drawings and I O tables
- FAT and SAT operator training spare parts and maintenance plan
- Remote support periodic inspections KPI dashboards and report templates
