joper joper 5kg
the 5kg is a shop roaster for smaller cafes, sample roasting, or roasters starting out. cast iron at this size gives you stable heat and good batch-to-batch consistency once you've dialed in your approach. 1kg minimum means you can roast samples or small single-origin lots without wasting coffee. manual controls put you in charge of every variable, which is either a benefit or a problem depending on your skill level. gas-fired with modulating burner. this isn't a beginner-friendly machine: you need to understand drum roasting and be comfortable making real-time adjustments. the cast iron drum takes longer to heat up than a steel equivalent, so plan your morning preheat accordingly. solid choice if you want hands-on control and thermal stability in a compact footprint.
