Line Scope and Throughput
The typical route is raw salt buffering and screening dosing and feeding forming and filling bag mouth shaping and sealing inline inspection coding and labeling case packing and palletizing data collection and traceability Small pouches cover 50 g to 2 kg medium heavy bags cover 5 kg to 25 kg Small pouch lines target 80 to 140 bags per minute medium heavy bags target 12 to 22 bags per minute
- Unified HMI recipes to reduce downtime when switching SKUs
- Dust control and corrosion resistant options for salty cleaning and routine maintenance
- End to end data capture compatible with barcodes and batch traceability
Core Equipment Continuous Vertical Form Fill Seal Salt Packaging Machine
For small pouches Supports pillow flat bottom and stand up formats Choose continuous or intermittent motion by target throughput Dosing by cup or multihead weigher Contact parts configurable in 304 or 316L with sealed structures for salty environments and periodic washdown

Process Steps and Controls
- Pretreatment screening and decontamination optional de ironing
- Dosing by cup multihead weigher or screw matched to granularity and accuracy
- Filling vertical forming for small pouches open mouth bagging for medium heavy bags
- Sealing heat or ultrasonic for pouches heat or stitching with folded edges for heavy bags
- Coding and labeling batch date barcode or thermal transfer
- On line inspection dynamic checkweighing and metal detection with combined rejection
- End of line case packing palletizing and stretch wrap or over bag for moisture protection
- Data and traceability batch records and integration with MES and WMS
Inline Quality Control and Traceability
The combination of checkweighing and metal detection intercepts weight errors and foreign bodies Results are bound to batch data to produce traceable reports with separate reject paths for weight and contamination
Illustration Compact combination unit for weight and metal
inspection
- Dynamic weighing across common net weight ranges with statistics
- Multi frequency metal detection for ferrous non ferrous and stainless steel
- Barcode linkage to create batch level traceability records
Layout and Selection Guidance
- Straight or L shaped layout with centralized dust extraction at emission points
- Small pouch lines use continuous vertical machines with multihead weighers and auto bag handling
- Medium heavy bag lines use open mouth bagging with heat sealing or stitching plus moisture over bag
- Add hoods at drop and stitching points and guided chutes to reduce dust
Implementation and Services
- Line layout and interface lists deliver drawings and point tables
- FAT and SAT operator training spare parts and maintenance plan
- Remote support periodic checks and KPI report templates
