Stainless Steel Automatic Scraper Centrifuge Machine
Salt Packaging Machine Linked Line Solution
This integrated packaging line coordinates vertical bag forming, filling, sealing, and open mouth weighing bagging operations for salt packaging. The system ensures clean operation, moisture protection, corrosion resistance, fast changeover, and stable production rates.
Solution Overview
The complete packaging process includes: raw salt buffering and screening, dosing and feeding, bag forming, filling and sealing, open mouth bagging, inline checking and metal detection, coding and traceability, case packing and palletizing, with integrated data collection and reporting.
- Handles packages from 10 grams to 50 kilograms
- Compatible with pillow, stand-up, flat bottom, and open mouth bag styles
- Features unified recipes, quick change parts, and clear maintenance access
Core Unit: Vertical Bag Forming, Filling and Sealing Machine
The small pouch section processes granular and fine salt in one enclosure with integrated forming, filling and sealing. Designed for seam stability, clean access, and fast changeovers with food-grade contact materials.
- Production speed: 70-120 bags per minute (depending on bag style and film)
- Constructed with 304 or 316L stainless steel with sealed bearings and electrical housings
- Hygiene features include local extraction points and extended seal dwell
Dosing and Feeding Configuration
Granular Salt
- Uses combination weighers or electronic scales with buffer hoppers
- Target accuracy: ±0.2 to 0.5 grams based on weight and granularity
- Common pack sizes: 200g, 500g, 1kg
Fine Salt
- Uses screw or gravity dosing with negative pressure extraction
- Target accuracy: ±0.5 to 1 gram depending on flowability
- Options include desiccant insertion and gas flushing
Open Mouth Weighing and Bagging Station
Handles 10-50kg bags with automatic bag pick, opening, dosing, settling, shaping, de-aeration and sealing. Compatible with paper, woven, and PE bags, and integrates with palletizing systems.
- Special shaping and de-aeration reduce residual air and dust
- Multiple sealing options: heat sealing, stitching, or tape cover
- Service-friendly design with accessible guards and lifts
Process Control Points
- Pretreatment screening and optional iron removal
- Precision dosing based on granularity and throughput
- Bag forming and sealing for all package types
- Marking and coding with batch traceability
- Inline inspection with weight checking and metal detection
- Case packing and palletizing with moisture protection
- Comprehensive data collection and reporting
Inline Weight Checking and Metal Detection
Combined system detects underweight, overweight, and contaminated packages, with automatic rejection and traceable records.
- Covers all common net weight ranges and line speeds
- Multiple reject options: air blast or belt diversion
- Data interfaces for reporting and system integration
