How do I move from hand weighing to automatic packing of granules?
Practical guidance for granules: move from manual to semi-automatic and automatic production in sensible stages.
Direct answer
For granules, increase capacity in stages while keeping the product and pack range flexible. Reliable dosing depends on flow behaviour, bulk density, aeration, particle size, feeder control and the product drop into the pack. Start by measure current good output and labour by operation and record net weight distribution, giveaway, dust release, breakage and sustained packs per minute. Make one controlled change at a time so the original cause is not hidden by several new settings.

What usually causes this?
- buying for an optimistic peak rather than measured demand
- A change in bulk density and aeration or hopper geometry and agitation.
- moving to full automation before packaging formats are stable
- The equipment or handling method not being set for free-flowing particles that can bounce, flood or segregate.
- underestimating cleaning, setup and operator handling time
Checks to make in order
- Measure current good output and labour by operation
- Record net weight distribution, giveaway, dust release, breakage and sustained packs per minute using a representative sample.
- Forecast realistic low, normal and peak demand
- Check auger, vibratory or weigh-feeder setup, drop height and dust containment and pack support and product settling.
- Compare manual, semi-automatic and automatic cells
- Test the most difficult product and format
- Plan a layout and controls that allow later expansion
How to decide the next step
Granules involves free-flowing particles that can bounce, flood or segregate. Semi-automatic equipment often gives the best first step; full automation becomes stronger when demand and formats are stable.
If adjustment and maintenance cannot hold the required result across the complete product and pack range, compare the machinery route against a written acceptance test. The important comparison is sustained good output—not only maximum cycle speed.
What to include in your production brief
Supplying the information below makes it much easier to distinguish a setup problem from a machinery or packaging limitation:
- Representative product sample
- Bulk density range
- Particle or piece size
- Target weight and tolerance
- Pack dimensions and opening
- Dust, hygiene and cleaning requirement
- Samples that represent granules
- A short video of the current process and fault
