Are you struggling with finding an efficient and reliable powder packaging solution?
Packaging flowing powder requires auger or gravity fillers. In contrast, you need volumetric or paddle fillers for non-flowing powder packaging. That’s why you must choose the powder packaging machine based on your applications, such as food, medicine, or industrial.
With my 20 years of experience in this field, I’m here to guide you in picking the best powder packaging machine. So, let’s begin-
What Is a Powder Packaging Machine?
The powder packaging machine automatically packs the powdered items into cans, bags, bottles, pouches, and other types of containers.
The key functions of these machines are filling, sealing, labeling, and weighing the powder quantity of each packet. These machines are used in different industries to ensure hygiene and efficient packaging. You will find them in manufacturing factories of food, medicine, cosmetics, etc., that produce powdered products.
Basic Parts Of Powder Packaging Machine
- Hopper
Hooper is the large funnel-shaped container at the top of the machine. It contains the powdered product that goes through the packaging process. You can detach this part to insert/shift products or for cleaning.
- Fill Heads
The bottom of the hopper is attached to the fill head. It dispenses the powder from the hopper to the packets or containers. Based on the machine type, the fill head can be of two types: auger and volumetric.
- Level Control- Sensors
Level-control sensors detect the quantity of powder inside the hopper. It gives refilling alters when the powder level is low. Thus, it maintains the continuity of the packaging process. Similarly, it notifies you when there are overfilling issues.
- Agitator Blades
Agitator blades are stainless blades used to keep the powder inside the hooper in motion. It prevents powders from clogging. These blades can be of different types- flat blades, paddle blades, ribbon blades, or sweeping blades.
- Auger
The auger is a spiral-shaped component that transfers the powder from the hopper into the packaging container, ensuring accurate filling. You can adjust the speed and direction of the auger’s rotation based on requirements.
- Control System
The control system of the powder packaging machine contains the following-
- Programmable Logic Controller (PLC)
- Servo motor
- Human/Machine Interface (HMI).
The PLC acts as the brain of the machine. It manages various machine functions such as filling, sealing, weighing, and safety monitoring. The servo motor is also controlled by the PLC to ensure precise motion.
The HMI is a touchscreen display that monitors the machine. It provides real-time data on machine performance.
- Dusting Unit
The dusting unit minimizes dust generation during the filling process. An enclosed dusting hood is attached to the powder filling station. As the powder is transferred into the packets or containers, it captures the flying dust particles. This can be later reintroduced into the filling process. Thus, you can reduce production waste.
- Conveyor Unit
The conveyor unit acts as a moving platform, ensuring a continuous flow of packaging materials. It carries the empty containers, bottles, or pouches from the infeed area towards the filling stations. Conveyor units can be of several types, such as
- Belt conveyor
- Bucket conveyor
- Screw conveyor.
- Vibratory conveyor
How Does Powder Packaging Machinery Work?
- Firstly, you need to put the powder into the hopper and position the empty packets/containers of the packaging on the conveyor belt.
- The conveyor will place the containers under the filling head attached to the hooper.
- The machine measures the filling quantity and dispenses the powder into the packet/container.
- The filled containers are then transferred to the sealing station.
- Once the container is sealed, they are sent for labeling.
Type Of Powder Packaging Machine
Powder packaging machines can be classified into different types. These are as follows-
Based On Automation
- Manual Powder Packing Machine
Manual powder packing machines are manual devices, also known as hand-held machines. It has a handle to rotate to fill the powder containers. This kind of manual powder filling machine requires a lot of manual labor. However, it is cost-effective and good for small, home-based businesses. For example- you can use them as a powder masala packing machine or wet flour packing machine.
- Semi-Automatic Powder Packing Machine
In semi-automatic powder packing machines, the filling task is automated, but other segments are manually operated. For instance, you need to fill the hopper, adjust the packets, or move them once filled. Therefore, a technician is required to operate the machine. You can purchase a semi-automatic powder-filling machine on a limited budget.
- Automatic Powder Packing Machine
Automatic powder packaging machines are fully automated devices. You don’t need any manual function to operate the device. It has sensors to detect product quality. Thus, the hopper filling procedure is also automated.
These machines are excellent choices for large-scale production. All you need to do is provide data to the device with appropriate parameters and it will do the rest on its own.
Based On Design
- Inline Powder Packing Machines
In inline powder packing machines, the process starts and ends in the same line. Here, filling, sealing, and packaging occur in a linear direction. These types of machines occupy large spaces but have maximum visibility for inspection.
- Rotary Powder Packing Machines
Rotary powder packing machines use a rotary mechanism. In these machines, containers are filled, sealed, and labeled in a circular motion. It has a compact design, occupying little space. You will get one of the top four feeding lanes in rotary powder packing machines. So, these are ideal for large-scale productions.
Based On the Packaging Solution
- Automatic Can Powder Packaging Machines
Automatic can packaging machines are designed to fill powders in jars, cans, and bottles. They use a screw-type mechanism to dispense the powder into the cans. If you are working with free-flowing powders, automatic can powder packaging machines are a good option. They require no manual labor to fill or seal the cans after filling.
Based on packing style, automatic can powder packaging machines are composed of components such as powder filling, sealing, capping, and labeling machines.
- Powder Form Fill Seal (FFS) Machines
Form Fill Seal (FFS) machines fill powder, creating bags/ pouches from a roll of film. These machines can be of two types-
Vertical Form Fill Seal machines use film sheets to produce tube-like packaging bags. They take up little space for their vertical design and are ideal for small floor areas. These machines can be of different types based on packaging style-
- Pillow Powder Packing Machine
As the name suggests, these machines produce pillow-shaped packages. These are sealed from three sides. Pillow powder packing machines are widely used to pack powdered milk, coffee, flour, etc.
These machines produce small, single-use packets or sachets. They should be used for packing small-quantity powder products. Sachet packaging machines can be used for both flowing and non-flowing powders. You can use these machines as small spice packing machines or milk powder packaging machines.
- Stick Powder Packaging Machine
The stick pack machine is a versatile option for packing single-serve products. It produces three-sided sealed long narrow packs made of plastic, aluminum, or paper, suitable for nutritional powders, instant coffee powders, spices, etc.
- Horizontal Form Fill Seal (HFFS) Machines
A Horizontal Form Fill (HFFS) packaging machine uses film rolls to produce packets for filling powders. These films move in the horizontal direction, which is why they are known as HFFS machines. Here, packet manufacturing, filling, and sealing occur within a single machine.
Different from roll forming, premade pouch packaging machines use pre-made pouches, offering a more modern and convenient powder packaging solution. These machines use premade pouches to fill powders in various styles, such as doy-pack, quad, stand-ups, 4-side seals, etc.
Things To Know To Choose The Best Powder Packaging Machine
Note down some facts that you must consider before purchasing a powder packaging machine:
Determine The Powder Type: Free-Flowing or Non-Free-Flowing
Powder can be of two types: free-flowing and non-free-flowing. Free-flowing powders such as sugar and salt do not get sticky. On the other hand, powder that tends to stick together is called non-free-flowing powder. The filler type of the powder packaging machine differs for free-flowing and non-free-flowing powders.
Powder Type | Required Filler |
Free-flowing powder | Auger Fillers Volumetric Fillers Vibratory Fillers |
Non-free-flowing powder | Auger Fillers with Agitation Vacuum Fillers Compression Fillers |
Bulk Density
Calculating the bulk density of the powder is essential to determine the ideal pouch size for the powder. It determines the compressibility and flowability of powder under pressure.
But how to determine the bulk density of powder?
The formula for bulk density, (ρ) = M / V
Here,
ρ = Bulk density (g/cm3)
M = Mass of the powder (g or kg)
V = Volume of the powder (cm³ or m³)
High-bulk-density powders generally take up less space than low-bulk-density powders. For example, brown sugars or sands are high-bulk-density powders. They can be easily compressed. So you can fit them into small pouches. But low-density powders like roasted coffee don’t compress much. They are to be packed in larger pouches.
Besides, flowability is also a crucial factor here. Even with similar bulk densities, free-flowing powders will naturally pack denser than non-free-flowing powders.
Powder Property | Suggested Pouch Size |
High Bulk Density + High Compressibility | Smaller pouches might suffice(Example: brown sugar) |
High Bulk Density + Low Compressibility | You might still need larger pouches due to particle shape. (Example: some metal powders) |
Low Bulk Density + High Compressibility | Consider a pouch size that allows for some compression. (Example: instant coffee) |
Low Bulk Density + Low Compressibility | Larger pouches are likely needed to accommodate the powder volume. (Example: ground coffee) |
Installation Space: Machine Size
You must consider your factory’s area and vertical space size to pick the right machine size. HFFS machines or in-line machines take up large spaces. Meanwhile, VFFS or rotary powder packing takes up less space than other variants. So, if you have a small production area, go for these machines.
Bag/Container Style
Powders are filled in different types of powder packaging bags or pouches. And the machine type differs for the style of bag you use. For example, for single-use packs you will need powder sachet packaging machines. Whereas for bulk packaging powder box packaging machines are essential.
Therefore, you should first decide what type of bag you want to pack the products in, then decide on the machine type. The chart below will help you with selecting the right powder bag filling machine-
Powder Packaging Machine | Type of bag | Application |
Vertical Form Fill Seal (VFFS) | Sachet Bags Pillow Bags Stick Packs Gusseted Bags | Single-serve portions, samples, spices, free-flowing powders, instant coffee |
Premade Pouch Packaging Machine | Doy-Pack Stand-Up Pouches 4-Side Seals | detergent powder, milk powder, flour, spice, cocoa powder, ground coffee |
Automatic Can Powder Packing Machine | Can Bottle Jar | Powder milk, cosmetics, protein powder, coffee, pharmaceutical powders |
Production Capacity To Determine Packaging Speed
The speed of a machine is the number of packets it can fill in a minute. It is calculated as Packs Per Minute (PPM), which helps you track the machine’s daily production capacity.
You will find the production capacity in the machine’s manufacturer specification. A small-size powder packaging machine has a lower production capacity. Calculate your daily production requirement and purchase one accordingly. The chart below gives you an idea about the industrial production capacity of powder packaging machines:
Production Line Size | Production Capacity (units per day) | Recommended Speed (PPM) |
Small | 1,000 – 5,000 | 50 – 100 |
Medium | 5,000 – 20,000 | 100 – 200 |
Large | Over 20,000 | 200+ |
Construction Material
Powder packaging machines are made of stainless steel, aluminum, carbon steel, plastic & polymers. Among all these construction materials, stainless steel machines are the most durable. Though expensive, they are best for industrial-level production.
