Single Hopper Powder Filling Machine

Description

Single Hopper Powder Filling Machine is a specialized piece of packaging equipment designed for accurately dispensing and filling dry powders, granules, or micro-granular materials into containers such as bottles, jars, pouches, or bags. It typically features a single product hopper that feeds material into a volumetric dosing system, most commonly an auger filler. This setup is ideal for small to medium-scale production in industries like pharmaceuticals, food, cosmetics, chemicals, and nutraceuticals. Unlike multi-hopper or rotary systems, the single-hopper design is simpler, more compact, and cost-effective for lower-volume operations. Single Hopper Powder Filling Machine ensure precise fill volumes by controlling the rotation of the auger screw, which measures out exact portions without weighing the product. They are particularly effective for free-flowing or non-free-flowing powders that might clump or aerate.

The core mechanism relies on an auger housed in a close-fitting cylinder. Here’s a step-by-step overview:

Hopper Loading: Powder is loaded into the single stainless-steel hopper. An agitator or stirring bar prevents bridging or clumping, ensuring consistent flow.

Auger Activation: A servo motor or pneumatic drive rotates the auger at a precise speed. Each rotation displaces a fixed volume of powder from the hopper into the auger tube.

Dispensing: The measured powder is funneled through a nozzle into the container positioned below. Fill accuracy is maintained via a digital timer, PLC, or HMI touchscreen for easy adjustments.

Cycle Completion: The container is removed manually or advanced automatically. Dust control features, like vacuum extraction, minimize mess.

For non-free-flowing powders, add-ons like vibratory hoppers or de-aeration systems enhance performance. Speeds range from 10-50 containers per minute for single-head models.

Working Principle of Single Hopper Powder Filling Machine

The incoming dry bottle is fed through the Infeed Turn Table with suitably guided on the moving conveyor belt at the required speed for feeding. There is filling head mounted on machine top plate, when bottle reaches to the first filling station, it will be held by the bottle holder. Immediately it will be sensed by the bottle sensor as soon as it gets signals from sensor magnetic clutch starts to rotate which is mounted on auger shaft. It will fill the desired amount of powder to the bottle through auger, where rotation time is previously saved in PLC control. After filling bottle moves further for next operation. The main advantage of this machine is star wheel pick up system of bottle is directly connected with Auger rotation, so till bottle get filled with powder as per set value.

Duly filled bottles delivered on outfeed conveyor for capping operation.

Key Features of Single Hopper Powder Filling Machine

Single Hopper Design:

Hopper capacity often around 30 liters (varies by model), with built-in agitator/stirrer for smooth, consistent powder flow and to prevent bridging or compaction. Reduces waste and maintains head pressure.

Speed and Throughput:

Up to 20–45 containers/min (e.g., 30 bottles/min typical for single-head), depending on fill volume, powder type, and container size. Suitable for small to medium production; lower than multi-hopper models.

Material of Construction:

All product-contact parts are typically Stainless Steel 304 or 316 (food/pharma grade), with non-stick coatings on auger and funnel where needed. Heavy-duty, vibration-resistant frames for stability.

Adjustable Filling Range:

Typically handles 5g to 500g+ (or more, depending on auger size and tooling), with good accuracy (±1–2% or better for consistent powders under controlled humidity).

Safety & Compliance:

GMP-compliant design, overload protection, emergency stops. Often includes pneumatic bottle indexing or conveyor integration.

FAQ for Single Hopper Powder Filling Machine

What is a Single Hopper Powder Filling Machine and how does it work?

A Single Hopper Powder Filling Machine is a compact, auger-based system designed for accurately filling dry powders, granules, or micro-granular materials into bottles, jars, or containers. It uses a single stainless steel hopper with an agitator to ensure consistent powder flow. The working principle involves a sensor detecting the bottle, activating a magnetic clutch-driven auger screw that rotates for a precise time (controlled by PLC) to dispense the set volume of powder. Filled bottles then move to the outfeed conveyor. This makes it ideal for small to medium production runs.

What is the production capacity and filling accuracy of the Single Hopper Powder Filling Machine?

The machine (Model ADF-40) offers a production output of up to 30 bottles per minute, depending on powder characteristics, fill volume, and container size. It supports a filling range of 50g to 500g (with change parts for 5g to 100g+). Filling accuracy is typically ±1.5% to ±2% (or up to ±2-3%), achieved under controlled humidity when powder bulk density is consistent.

What types of powders and containers can this machine handle?

It is suitable for free-flowing and some non-free-flowing powders used in pharmaceuticals (e.g., dry syrups, injectables), food, nutraceuticals, chemicals, and cosmetics. The machine works best with consistent bulk density powders. It handles various bottle sizes (change parts required for star wheel, funnel, and auger) with a 30-liter hopper capacity. All contact parts are SS 316 for hygiene and GMP compliance.

What are the key features and advantages of the Single Hopper model?

Key features include:

Compact linear GMP design with SS 316 contact parts
“No Bottle – No Filling” system with PLC control and HMI
Built-in agitator in the hopper to prevent bridging
Heavy-duty vibration-resistant structure
Easy changeover with quick-adjustable parts

Advantages: Cost-effective for moderate production, simple operation & maintenance, smaller footprint, and reliable precision compared to multi-head systems.

What maintenance and environmental requirements does the machine need?

Regular maintenance involves cleaning the auger, funnel, and hopper (easy tool-less or removable design). Keep the machine in a controlled environment with humidity below recommended levels (typically <28-40% RH) to maintain accuracy and prevent powder clumping. The machine requires 0.5 HP power and standard 440V, 3-phase, 50 Hz supply (customizable). Routine checks on sensors and lubrication ensure long-term performance.
