Automatic Food Powder Packaging Machine for Flour, Milk Powder, Coffee and Spices

This automatic food powder packaging machine is designed for flour mills, milk powder producers, coffee and cocoa processors, seasoning factories and powdered beverage plants. It provides enclosed screw feeding, auger dosing and vertical bag sealing for small and medium powder packages.

Food Processing Applications

• Flour, starch and yeast powder packaging in flour and bakery ingredient plants
• Milk powder, soy milk powder and powdered beverage packaging
• Coffee powder, cocoa powder and ice cream powder packaging
• Seasoning, spice, meal-replacement and other food powder packaging

Why It Fits Food Powder Production

The enclosed feeding structure helps control powder dust, while removable product-contact parts simplify routine cleaning. Adjustable bag dimensions, dosing settings and sealing temperatures allow the BG series to support different retail and food-service pack formats.

Automatic Vertical Auger Powder Packaging System

This roll-film vertical powder packaging system combines a screw feeder, a vertical form-fill-seal machine and an auger dosing hopper. The PLC and touch-screen control system coordinates bag forming, dosing, filling, sealing, batch coding and finished-bag cutting in one automatic workflow.

Machine Structure and Working Process

Enclosed Screw Feeder

The screw feeder transfers bulk powder from the material hopper to the dosing hopper at a controlled rate. Its enclosed conveying structure helps reduce airborne dust during production.

Auger Dosing Hopper

The rotating auger controls the powder discharge volume and can be configured for powders with different bulk densities.

Vertical Form-Fill-Seal Machine

The main machine unwinds the film, forms the bag, seals the bottom, fills the powder, completes the vertical and horizontal seals, and cuts the finished package.

PLC and Touch-Screen Control

Operators can set bag length, packing speed, filling quantity and sealing temperature from the touch screen. Multilingual control options can be configured.

Core Machine Features

• Automatic feeding, dosing, bag forming, filling, sealing, coding and cutting
• Auger dosing designed for fine and free-flowing powder products
• Enclosed powder transfer structure to help control dust
• Back-seal and three-side-seal bag configurations available according to the project
• Independent sealing-temperature control for different heat-sealable films
• Stainless-steel construction and removable product-contact components for cleaning
• Optional nitrogen flushing or vacuum functions for powders that require additional shelf-life protection
• Automatic fault alarm and straightforward daily maintenance

Suitable Powder Characteristics

The machine is intended for fine or ultra-fine powders with suitable screw-feeding characteristics, including powders that are slightly hygroscopic or prone to dust. Products with severe caking or oversized particles require material testing and a suitable feeding configuration before machine selection.

For suitable small-format products, routine dosing can be configured for accuracy within ±1 g. Actual accuracy depends on powder density, flowability, target dose and auger configuration and should be confirmed through material testing.

Production Line Integration

The machine can operate independently or connect with upstream feeding equipment and downstream conveyors, metal detectors, checkweighers, bag collection systems or palletizing equipment. Final configuration depends on the product, bag format, required output and factory layout.

Information Required for Machine Selection

• Powder name, photos and flow characteristics
• Target filling quantity and acceptable accuracy
• Bag width, bag length and sealing style
• Packaging film structure and thickness
• Required production speed, voltage and workshop layout
