A tool for evaluating green coffee, training, and developing ideas for production.
Choose a sample roaster for repeatability with small batches, data quality, and ease of comparing samples under consistent conditions—not maximum output.

01/quick verdict
For green coffee purchasing and laboratory work, consistent 50–300 g batches and roast-profile records matter most. A 500 g–1 kg machine is more suitable if sampling must also accommodate pilot commercial batches.
results cannot be copied directly to a production drum
small batches are sensitive to the operator's procedure
some home roasters do not provide the required repeatability
03/assessing the choice
From calculations to technical requirements
01
Procedure matters more than the interface
Record the batch weight, machine preparation, charging procedure, evaluation points, and sample resting time. This makes results from different days and operators comparable.
consistent warm-up
weighing with calibrated scales
a standard notes template
blind tasting where possible
02
What to check during a demonstration
Request several repeat roasts using the same coffee lot and ask for the data to be exported. Assess variation in results and ease of cleaning between samples, not how attractive the graph looks.
minimum stable batch load
heat and airflow response
cooling speed
log export
03
Connecting sample roasting to production
Use the sample roaster to test ideas about roast development, energy balance, defects, and the sensory target. Develop the production profile afresh to account for its different thermal system.

KALEIDO M1 Standard 50–200g Automatic Mini Coffee Roaster
Yes, for preliminary assessment, if results are repeatable and the procedure is consistent. For commercial purchasing, measurable and comparable results usually matter more.
Do I need automated profile control?+
Automation helps repeat a procedure, but does not replace calibration, weight checks, or sensory evaluation.
What batch capacity should I choose?+
Start with the available sample weight and your tasting protocol. Pilot commercial batches require additional batch capacity.
Ready to check the entire configuration?
Calculate the required output, then plan the roaster together with the premises, cooling, and packaging.
