Powder packing machines

From bulk powder to a measured, sealed pack.

Pack flour, seasoning, ground coffee or nutrition powder in the format your customers use. Comwin supplies the powder feeding, dosing and packing equipment, from a filling unit to an automatic bagging line.

  • Auger filling matched to powder flow and dose
  • Roll-film bags, premade pouches and small portions
  • Cleaning and recipe changes included in the layout

How will your customer use the powder?

Choose the selling format first. It determines how the pack is formed, filled and closed.

Sealed retail bags
Turn bulk flour or seasoning into measured units for sale or kitchen use. Film forms each bag on the machine; a different bag width needs the appropriate forming parts.
Resealable pouches
Keep coffee or nutrition powder in its original pack between uses. The machine fills supplied pouches and heat-seals above the zipper.
Sachets and sticks
Give the customer a single serving or recipe addition without measuring from a larger bag. Small doses need filling parts sized for the portion.
Jars
Provide a rigid container for repeated scooping. The opening must accommodate the filling tube and the intended use.

Film barrier and sealing conditions determine protection during storage. Compare other product formats in our bag packaging range.

A steady powder feed makes a more consistent fill

An auger dispenses powder by turning a screw. The same number of turns can deliver a different weight when the powder packs more or less densely around it.

Feed the auger consistently
A screw conveyor or other suitable feeder replenishes the dosing hopper. Level control and appropriate agitation help maintain supply without excessive compaction.
Finish the fill before sealing
The filling tube directs powder into the bag. Discharge timing, headspace and dust capture keep loose powder away from the sealing jaws.
Check the actual net weight
Use filled-pack weight checks and the applicable empty-pack tare. Where needed, feedback adjusts later doses; the feedback arrangement is specified with the filler.
Plan access for recipe changes
Identify how to empty the hopper and remove the screw, tube and other contact parts. A cleaning method must suit every powder sharing that path.

Flour or seasoning in roll-film bags

A measured retail or foodservice pack, made from a reel of film.

  1. Lift powder to the hopper
  2. Dose through the forming tube
  3. Seal the bag
  4. Carry the pack away

The shown system has a floor-level feed hopper, screw conveyor, auger dosing unit, vertical bagger and takeaway conveyor. The screw lifts powder into the dosing hopper; the auger releases a portion through the forming tube. The bagger makes the rear seam and end seals before discharging the finished bag.

Fill weight, powder density and bag width determine the auger and forming parts. A light, aerated powder can need more settling space than its weight suggests.

Powder in premade resealable pouches

Coffee or nutrition powder that customers take from the pack over several servings.

  1. Pick and open pouch
  2. Fill with powder
  3. Let the fill settle
  4. Seal the top

A pouch-handling machine takes a supplied bag, opens its mouth and holds it beneath the powder filler. An auger doses into the supported pouch; settling leaves room for the top seal. For a zipper pouch, opening and filling tools must clear the zipper without contaminating it.

The pouch platform and powder filler are selected together. Scoop insertion, if required, adds its own handling operation.

Powder sachets and stick packs

Choose the portion shape and dose together; the pack width limits the space available for filling.

Closed flat powder sachets beside narrow powder stick packs
Flat sachets and narrow sticks for individual powder portions.

Single-serving powder packs

Seasoning additions, drink mixes and other powders dispensed one portion at a time.

  1. Feed the dosing units
  2. Fill the formed portions
  3. Seal and separate

A flat sachet gives a broad pack face; a narrow stick makes a slim individual portion. Each needs its own forming and sealing geometry. The dosing screw or other suitable metering unit must deliver the small portion cleanly within the sealing cycle.

More lanes increase the number of packs made per cycle. They also require even product supply and separate checks of the portions and seals from each lane.

Auger filling with jar handling and closing

A rigid container for nutrition powder or other products used repeatedly.

  1. Position the jar
  2. Fill with powder
  3. Fit the closure

The jar is held beneath an auger filler, then moves to its closing operation. Opening diameter, dust around the neck and the selected cap determine the handling and closure parts.

A bagging system and a jar system use different package handling. If both are required, their filling and closing arrangements are specified separately.

Two powder production decisions

Does the dose drift after a hopper refill?

Conveyor weighing equipment for checks after filling. Select the weighing range and pack support for the finished bag.

A refill can change the way powder settles around the auger. Check the first packs after replenishment as well as packs from the middle of the run.

  1. Record the refill point
  2. Compare actual net weights
  3. Inspect headspace and seals

Record the recipe, auger setting, refill point and actual net weights. If weight changes, review hopper supply and dosing settings together. Also check fill height: a pack can reach its target weight while leaving too little clean space for sealing.

A conveyor weigher checks the filled pack downstream. Bag support, belt length and weighing range must suit the pack; automatic dose feedback is a separate function.

Flour and ground coffee need different filling trials

Particle size, settling and movement through the hopper determine the screw geometry and filling time for each powder.

  1. Run each product
  2. Compare feed and filled packs
  3. Define parts and cleaning

Run representative material from each product. Compare delivery through the screw, actual fill weights and the space occupied in the pack. Coffee freshness requirements also affect the packaging specification; flour dust makes the filling and sealing area a different concern.

For a shared machine, list the settings and contact parts for each recipe, then establish the emptying and cleaning sequence. Confirm the first packs after every change.

Powder packing questions

Can one machine pack several powders?

Yes, where their flow, dose and packaging fit the selected equipment. Some changes use stored settings; others need a different auger, forming part or cleaning procedure. We assess the stated product range together.

Is an auger filler a complete packing machine?

It meters the powder. An automatic powder packing machine also needs the appropriate bag forming or pouch opening, filling coordination and sealing. A standalone filler can be used with operator-presented packs.

Can a retail-bag machine also make small sachets?

That depends on the forming parts, usable bag dimensions and filling range. Small portions can need a dedicated dosing and sealing arrangement, even when the powder is unchanged.

What determines a powder packing machine quotation?

The powder, fill weight, bag or container, required output and cleaning needs establish the equipment list. Send those details so the quotation covers the intended filling and closing process.

Can you assess industrial powders or large sacks?

Send the product and sack specifications for an equipment assessment, including product handling, supported filling, closing and any special process requirements.
