What Is a Double Auger Powder Filler?

A double auger powder filler uses a dual-screw conveying system, specifically designed for powdered materials. It offers efficient and precise packaging capabilities, accurately controlling the amount of material per bag based on the set weight. Widely used in the food, chemical, and pharmaceutical industries, it boosts production efficiency while meeting hygiene requirements—perfect for packaging 25-50kg batches of powder.

How It Works

1. Powdered materials are conveyed to a weighing hopper via the synchronized rotation of the twin-screw feeder.
2. A sensor monitors the weight in real time; once the preset weight is reached, the feeding stops automatically.
3. A bag-clamping device holds the packaging bag in place, and after the material drops into the bag, heat sealing or stitching completes the closure.
4. The entire process is fully automated by a PLC control system, ensuring high precision (error ≤ ±0.1%) and strict hygiene standards.

Key Structural Features

• All-Stainless Steel Body: The main machine frame and all parts that touch materials (like the hopper and screws) are made of 304 stainless steel. This makes the machine corrosion-resistant, compliant with food-grade hygiene standards, and easy to clean and maintain.
• Twin-Screw Feeding System: The dual screws rotate in sync to move materials, with a frequency converter controlling the motor speed. It supports three-speed adjustment (fast, medium, slow), balancing packaging speed and accuracy (error ≤ ±0.1%).
• Multi-Functional Bag-Clamping Device: It works with various bag types (woven bags, paper bags, plastic bags, etc.). Combined with automatic weighing and sealing processes, it enables fully automated operation.

Typical Applications

• Designed specifically for packaging 25-50kg batches of powder.
• Food Industry: Ideal for powdered ingredients like sugar, milk powder, coffee powder, flour, seasonings, and spices.
• Chemical Industry: Used to package chemical powders, pigments, fertilizers, catalysts, detergents, and other chemical raw materials.
• Pharmaceutical Industry: Suitable for fine powders such as medicinal powders, nutritional supplements, and herbal powders.
• Agricultural Industry: Works for packaging granular and powdered agricultural products like seeds, fertilizers, and pesticides.

Main AdvantagesMachine Parameters

1. High-Precision Measurement

• The synchronized twin-screw feeding system, paired with real-time weight monitoring via sensors (error ≤ ±0.1%), ensures stable measurement.
• Three-speed adjustment (fast, medium, slow) adapts to materials with different densities, maintaining accuracy across various products.

2. Hygiene & Safety

• All main components and material-contact parts use 304 stainless steel—they’re corrosion-resistant and easy to clean.
• Complies with food-grade GMP and pharmaceutical hygiene standards, effectively preventing material contamination.

3. Efficiency & Energy Savings

• PLC automated control enables continuous operation, with an output of hundreds of bags per hour.
• Optimized circuit design reduces energy consumption, and a self-diagnostic system for faults minimizes downtime risks.

4. Flexible Adaptability

• Switching between different product types takes only 10 minutes, making it suitable for small-batch, multi-variety production needs.
• Works with multiple bag types (stand-up pouches, woven bags, etc.) and material types (powders, granules).
