joper joper 30kg

the 30kg is a production roaster for operations doing 200-400kg per day with manual control. 6kg minimum batch keeps you flexible for smaller lots, though that's not where this machine lives most of the time. cast iron drum means serious thermal mass: heat stays stable through the roast and recovers well between batches. you can push 100-120kg per hour if you're running tight cycles, but that requires a skilled roaster who can read the beans and adjust gas and airflow on the fly. no profiling software, no automation. this works for roasters who learned on manual machines and prefer direct control, or for operations where labor cost isn't the primary constraint. the cast iron adds durability and roast quality but also weight, cost, and longer heat-up windows. solid choice for traditional roasting at medium production scale.
