· Characteristics of the Powder Products

Can powder filler

Can powder filler

Powders possess definite and unique physical features, some are free-flowing whereas others are non-free flowing.

Still, some powders may be semi-free flowing.

In the case of free-flowing powders such as granulated sugar or tablet salt, you will need a mechanism of stopping the flow of powder.

The commonly recommended means is the use of a spinner disc.

This method involves mounting a sauce-like disc at the edge of the protruding auger.

Its function is to prevent the powder from flowing.

When dealing with non-free flowing products, you would need a large auger that can swiftly force all the trapped powder down into the funnel.

Moreover, you can control the mode of agitation in a manner such that it speedily break off between the fills to prevent overworking and compaction of the powder.

In situations where the powder gets filled with air as it moves downwards into the hopper, alter the mode of agitation so that it constantly run to force out the air.

In cases whereby the powder is filled with air as it trickles down into the hopper, change the agitation mode so that it continuously run to expel the air.

Generally, a larger hopper assists in homogenizing and de-aerating the powder product by making them go through more agitation, consequently resulting in longer residence time.

In the case of semi-free flowing powder products including such instant coffee powder, which are very delicate may get damaged when the hopper segment has a bigger auger with over-flights.

Therefore, to efficiently handle products of this type, utilize an auger having parallel flights.

Om the other hand,a semi-free flowing powder may rebound even after stopping of the auger.

In such a situation, start off a little back pressure to keep back the products in the funnel by installing a washer below the auger.

What are the Advantages of Vacuum Can Powder Filler?

  • Maintains the integrity of products since the breakdown of powder is very minimal.
  • Generates minimal or no dust.
  • Found in both semi-automatic and fully automatic types.
  • Fills both free-flowing and non-free flowing powder products.
  • Easy to clean and permits fast changeover of parts

What is the Difference between Inline and Rotary Can Powder Filling Machine Layout?

There exist two main designs for can powder filling machines: Inline and Rotary.

The main difference between the two models is in the machine layout.

An inline can powder filler performs the can powder filling in a straight line, with the starting and ending points of the procedure at opposite sides, calling for more floor space.

How do Can Powder Filler Work?

As we have seen, there are many types of can powder filler which have different working principle.

Therefore, let’s look at how the two most common can powder filling machines work.

· How Auger Can Powder Fillers Work

The filling motor rotates the auger at a constant speed to eject the powder products from the tube.

In the meantime, the mixing motor also rotates the stirring bar which has agitation bar attached in a counter-clockwise direction to that of the auger.

The bar and the blade de-aerate and blend the powder.

Moreover, the agitation blades make sure there is constant filling of the auger flights.

The powder products continuously flow into the funnel through a trap door and eventually fills into a ready can.

· How Net Weight Can Powder Fillers Work

The process begins by the powder products flowing from the hopper via conveyor belts or vibratory trays.

The movement of powder through belts or plates relies on the type of products.

The powder then goes direct into the bucket attached with a load cell.

As the weight of the bucket approaches the set weight, the dosing system slows down to a dribble feed speed.

You may need to add an extra belt or tray particularly for the dribble speed in operations where you require accurate results.

When the target weight reaches, the dribble speed finally stops.

The can powder filling machine, at this point would be ready to dispense its contents via a trap door into the container.

What Powder Filling Techniques are there?

Powder filling industry apply two common powder filling technologies as discussed below:

Tin powder filler

 Tin powder filler

· Volumetric Powder Filling Technology

Volumetric powder filling technique concentrate on the capacity of the fill.

This implies the number of rotations of the auger, for instance, is directly proportional to the amount of fill in a can.

This concept involve either single or multiple augers, regardless whether you are employing a semi- or fully automatic can powder filler.

You may connect a volumetric powder filling machine to a weigh cell to optimize its operation.

This is crucial because the weigh cell:

  • Eliminates (minimal/excessive) weights
  • Efficiently registers and displays the fill weight.
  • Makes up for any trend changes in the fill density.

With the kind of information determined by the weigh cell, the PLC automatically transmits it back to the filling head.

In turn, it starts appropriate action either by decreasing or increasing the rate of rotation of the auger.

Nevertheless, even when you use a semi or fully automatic can powder fillers, you may still get some negligible degree of error.

It is insignificant when filling light weight products such as oral dry suspensions into containers.

However, if you need completely no error in weights, then you will have to perform some modifications.

Add tare and gross weighing gadgets to the volumetric powder filler so that you would utilize two weigh cells.

The tare weighing device determines the weight of unfiled bottle, while the gross weighing device establishes the weight of full bottle.

Eventually, when working out the net weight, you minus the tare weight from the gross weight.

· Gravimetric powder Filling Technology

A fill-by-weight filling can powder filler may be your best choice because of a number of factors:

  • Tare weight inconsistency
  • criticality of the fill weight,
  • Inconsistencies in product density
  • Give-away in cost of product
  • Need to verify the real fill weight filled.

Powder filling machines comprising load cells or balances can be found in several configurations, though they all apply three main means of regulating the fill weight:

· Setpoint (dynamic weighing)

In this mode, the auger operates at a single speed and the live fill weight determined by the load cell.

The system will stop filling after reaching the pre-set setpoint weight.

The resultant weight will be a sum of the setpoint weight and any inflight material.

· Bulk and Dribble (dynamic weighing)

Here, the auger works at a high speed for most of the fill (bulk) and then reduces speed to a dribble speed for the rest of the filling.

The load cell keep track of the live fill weight and gives alert for the dribble fill to pause.

· Bulk and Feed Forward (static weighing)

In this case, the auger operates at a high speed for the better part of the fill (bulk) but gets stopped just before reaching the set fill weight.

The load cell measures a static weight and the needed top-up fill is worked out and changed into a volumetric fill.

Even though the top-up fill volumetric, you can attain a general accuracy of ±0.2%.

The commonly applied configurations include:

· Single Head, Gravimetric

In this type of configuration, you can use a single weigh-cell located directly below the filling head exactly in the same manner as when powder filling semi-automatically: “bulk and dribble’, “bulk, predict and top-up”, and “single shot”.

With the help of the weigh-cell, you can tare weigh the unfilled container and acquire data as needed.

· Dual Head, Volumetric Bulk Fill with a Gravimetric Top-up

Alternatively, you could use two filling heads, but rather than the two heads dispensing onto two live weigh-cells to double the production, you could use a bulk and top-up system.

This is beneficial because it gives the optimum of speed and accuracy.

The volumetric first head with a large auger, quickly bulk fills, and the second head having a more precise smaller auger performs the gravimetric top-up fill.

· Dual Head, Bulk and Predict

For even higher speed and accuracy, you can move the weigh-cell between the two filling heads.

Converting it into a bulk fill, predict forward and top-up device with instant weighing.

In this configuration, the weigh-cell would communicate back to the bulk filling head to sustain the quantity of the bulk fill, communicate forward to the top-up head, and estimate the required top-up dose.

All these three operations take place simultaneously.
