Salt Packaging Machine Assembly Line Solution
High Speed VFFS and Open Mouth Bagging Integration
A turnkey solution centered on packaging machines for small and medium heavy bag formats, designed for hygiene, moisture and corrosion protection, with fast changeover and stable throughput.
Solution Overview
The line is built around stability, hygiene, traceability and scalability. A typical flow includes: raw salt buffering, screening and decontamination, dosing and feeding, filling and forming, sealing or stitching, in-line checkweighing and metal detection, coding and labeling, case packing and palletizing, with data and traceability.
- Covers 50 g to 25 kg formats with multiple bag materials
- Unified HMI recipes to minimize changeover downtime
- Dust control and corrosion resistant design for long term stability
Core Module: 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. Cup or multihead weighing available. Contact parts in 304 or 316L optional with sealed construction for salty environments.
VFFS forming filling sealing machine can link to upstream screening and downstream inspection
- Short film path and stable sealing to raise hourly output
- Recipe memory and quick change forming sets for multiple SKUs
- Optional IP66 and corrosion resistant construction
Products and Sizes
- Products: sea salt, rock salt, refined salt, iodized salt, low sodium salt, seasoning blends
- Sizes: 50 g to 2 kg pouches and 5 kg to 25 kg medium heavy bags
- Materials: laminate, paper, plastic PE with moisture barrier options
Core Module: 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 for a fully integrated line.
Open mouth bagging unit for 5 kg to 25 kg salt
- Fast change between bag sizes compatible with paper, plastic and PE
- Linked weighing and conveying to reduce drop height and dust
- Clear maintenance access to shorten downtime
Standard Process and Control Points
- Pretreatment: screening and decontamination (optional de-ironing)
- Dosing by cup, multihead weigher or screw based on granularity and accuracy
- Filling: VFFS for small pouches, open mouth bagger for medium heavy bags
- 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. The inspection results are linked 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 metal detection for stainless and non-ferrous
- 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 IP66 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
