Automatic VFFS Powder Packing Machine for Flour, Spices and Milk Powder

The Automatic Vertical Form Fill Seal (VFFS) Powder Packing Machine is a fully integrated, high-speed packaging system designed for the automated packaging of fine and ultra-fine powders. Built for continuous industrial production, this machine handles the complete packaging process, from roll stock film forming through auger filling, vertical and horizontal sealing, date coding, and bag cutting, in a single streamlined operation.

Whether you are packaging flour, milk powder, chili powder, masala, spices, cocoa powder, cornstarch, almond powder, or tapioca starch, this system delivers consistent output, precise fill weights, and hygienic handling across every production cycle. It is equally suited to chemical and industrial powder applications including leaven enzyme, soda powder, and concentrated washing powder.

How the System Works

The VFFS process begins with a flat roll of laminated packaging film. The machine automatically feeds the film over a forming collar, shapes it into a vertical tube, and seals the longitudinal seam. The integrated screw metering system then deposits a precisely measured dose of powder into each bag through an auger filler before the top seal and cut are applied, completing a finished package. The entire sequence bag forming, powder filling, sealing, coding, and separation happens automatically, cycle after cycle, without manual intervention.

This continuous motion design supports production speeds of 15 to 60 bags per minute and is configurable across multiple fill points for high-volume production environments.

• Bag Width: 50–250 mm
• Film Width: 520 mm
• Packing Speed: 15–60 bags/min
• Power: 2.2 kW, 220V 50/60Hz
• Machine Dimensions: 1080 × 1500 × 1600 mm
• Supports pillow bags, gusset bags, and four-edge sealed bags
• Multi-language touchscreen interface with PLC control
• Servo film pulling system ensures accurate positioning and consistent bag length
• Independently adjustable temperatures for vertical and horizontal sealing bars
• Stores up to 10 product recipes for fast format changeover
• Automatic color-mark and colorless-mark detection with alarm system
• Compatible packaging materials: BOPP/CPP, BOPP/VMPP, CPP/PE

2. Screw Metering Machine (BS-50L)

The auger filler is purpose-built for non-free-flowing and cohesive powders that cannot be handled by volumetric cup or vibratory weighing systems.

• Hopper Capacity: 50 L
• Fill Weight Range: 200–1000 g
• Filling Speed: 40–120 bags/min
• Accuracy: ±2%
• Power: 1.7 kW, 220V 50/60Hz
• Stainless steel food-contact construction throughout
• Tool-free disassembly for rapid cleaning and product changeover
• Servo motor controlled for consistent screw rotation and fill accuracy
• Height-adjustable mounting with interchangeable screw accessories for different powder types

3. Screw Feeding Machine

This unit maintains a steady and controlled flow of bulk powder into the metering hopper, preventing bridging and ensuring continuous operation.

• Feeding Capacity: 3 m³/hour
• Hopper Capacity: 230 L
• Screw Diameter: 114 mm
• Power: 2.5 kW, 220V 50/60Hz

4. Belt Conveyor for Finished Products

A food-grade PP belt conveyor handles the smooth downstream transfer of sealed packages away from the packing station.

• Belt Speed: 30 m/min
• Belt Material: Food-grade polypropylene (PP)
• Power: 40 W, 220V 50Hz
• Conveyor Dimensions: 1600 × 520 × 1000 mm

Key Performance Advantages

This VFFS powder packaging system is engineered to solve the most common production challenges in powder handling and flexible packaging:

1. Full Process Automation: Integrates bag forming, powder filling, sealing, date coding, and cutting into a single uninterrupted workflow, significantly reducing labor dependency and human error.
2. Precision Fill Accuracy: Servo-controlled auger metering achieves ±2% fill accuracy, which is critical for weight compliance, reducing product giveaway, and meeting retail labeling requirements.
3. Versatile Powder Handling: The screw metering system is specifically designed for cohesive, non-free-flowing powders: including fine spice powders, wheat flour, milk powder, and starch: that cannot be handled reliably by other filling technologies.
4. Multiple Bag Formats: The same machine produces pillow bags, gusseted bags, and four-edge sealed bags, providing packaging format flexibility without major equipment changes.
5. Hygienic Construction: All product-contact surfaces are stainless steel. Tool-free disassembly allows thorough cleaning between product runs, supporting food safety compliance and cross-contamination prevention.
6. High-Speed Continuous Operation: Multiple blanking points and support for continuous bag making allow the line to sustain output rates up to 60 bags/min for high-volume production environments.
7. Smart Control and Recipe Storage: The PLC-based touchscreen stores up to 10 product recipes, enabling rapid format changes across different products, bag sizes, and fill weights with minimal downtime.
8. Broad Film Compatibility: Supports BOPP/CPP, BOPP/VMPP, and CPP/PE roll stock films, giving manufacturers flexibility in packaging material selection for different product shelf-life and barrier requirements.

Industry Applications

This machine is deployed across a wide range of industries where automated, hygienic, and accurate powder packaging is required:

Food Industry

• Wheat flour, cornmeal, tapioca starch, almond powder, cocoa powder, baking powder
• Milk powder, instant beverage mixes, protein powder
• Coconut powder, cornstarch, baking mixes

Spice and Seasoning Industry

• Chili powder, pepper, turmeric, curry powder, masala blends
• Seasoning mixes, concentrated flavor powders, dry sauce mixes

Chemical and Industrial

• Soda powder, leaven enzyme, concentrated washing powder
• Food-grade chemical powders, agricultural dry formulations

Why This Machine Is the Right Investment

For food manufacturers, spice processors, and chemical producers seeking to move from semi-automatic or manual filling to full production automation, the VFFS powder packing system represents the most cost-effective route to high-speed, accurate, and hygienic packaging. The combination of servo-driven auger filling, PLC recipe management, stainless food-grade construction, and multi-format bag capability means the machine can grow with your product range without requiring replacement equipment.

The system’s compatibility with standard roll stock film, which costs significantly less than pre-made pouches, also provides ongoing operational savings at scale, making this an investment that improves both throughput and total cost of ownership over its lifespan.
