Coffee packaging automation: how to plan a meaningful production trial
A packaging machine rarely spends its working day handling just one coffee, one pouch and one uninterrupted production run. Roasteries switch between products, fill weights and customer orders. A useful packaging trial therefore starts with a specific question: can this particular workflow reliably produce our saleable bags? A prepared practical trial provides a stronger basis for decisions than a short demonstration using someone else's materials.
1. Describe the order before the machine
Start with a concise trial brief. List the coffees, planned fill weights, pouch variants and typical order size. Add the steps that currently take time: filling, checkweighing, sealing, labelling or placing bags in cartons. This keeps the operational problem you want automation to solve clearly in view.
Separate your most frequent order from a demanding special case. A standard pouch used regularly deserves its own trial. An occasional unusual size does not automatically have to determine the entire machine configuration. Record which variants are essential and which could be introduced later. This gives everyone involved a shared basis for the demonstration.
2. Test your own coffee and pouches
Send the supplier samples from your intended production, rather than relying on a drawing or product photograph. Identify each sample clearly and include the packaging supplier's information, such as dimensions, material structure and processing guidance. Treat different pouches as separate variants even when they look similar.
Your coffee selection should also reflect normal operations. If you process several roasts, plan separate runs for them. Use clearly labelled batches and document their condition on the trial day. Record any material substitutions during the demonstration. Otherwise, it can be difficult to establish whether an improved result came from an adjustment or a different sample.
3. Agree what an acceptable result means
Before starting, agree on the criteria for an acceptable bag. These might include the recorded fill weight, a properly formed seal, undamaged packaging and legible identification. Specific limits and inspection methods need to suit your product, packaging material and operational quality plan. A visual check alone does not replace an agreed assessment of seal quality.
Also decide who will carry out the checks and how deviations will be recorded. Separate accepted bags, units needing rework and rejects. Note the reason for each interruption instead of recording only a final total. The result should be a usable working record that your team can compare with a later trial or repeat run.
4. Measure the complete workflow
Do not start the clock only once everything has been perfectly prepared. Record setup, material replenishment, product changes and handover to subsequent operations separately. Observe whether one operator can supply the machine, inspect bags and prepare cartons within the proposed workflow. These tasks belong in capacity planning even when they happen outside the machine.
Consider a simple calculation: if a trial produces 600 accepted bags during an observed period of 50 minutes, the measured throughput is twelve accepted bags per minute. This is a hypothetical example, not a performance specification for any product. It explains why the measurement period and quality criteria should always accompany the number. A short peak rate answers a different question from the output of a complete order.
5. Include a real changeover
After the standard run, ask for a second agreed variant. Record the manual steps, setting changes and time needed to produce the first acceptable bag. Document cleaning and product separation according to the intended operating procedure. The changeover should be demonstrated clearly rather than described only as straightforward.
Keep labelled reference bags, photographs and the approved settings record together. Assign an owner and a next step to each unresolved issue. This allows the trial to end with a decision that others can review: approve the tested setup, continue testing under stated conditions or investigate another configuration.
Checklist for your next consultation
Match original coffee and pouch samples with their material information.
Specify the standard order, additional variant and required changeovers.
Agree inspection criteria, methods and documentation before starting.
Record accepted bags alongside all interruptions.
Keep reference samples and unresolved questions for the review.
From a trial brief to a suitable configuration
According to its product description, the KÜHNE premade-pouch machine listed in the Kühne Kaffee catalogue combines bag picking, opening, weighing, filling and sealing. Confirm the configuration for your coffee and packaging using your own samples. The catalogue image shows a dried-fruit application; it does not replace a trial with coffee.
Prepare your brief and discuss the intended packaging workflow with Kühne Kaffee. A clearly documented practical trial makes the next steps understandable for production, quality assurance and purchasing teams, while keeping the decision grounded in the materials and orders you actually handle.
