coffee-tech engineering coffee-tech solar 9
the Solar 9 sits between sample roasters and production machines with 1 to 9 kg batches. it's aimed at roasters who need production consistency but still roast enough single-origin microlots that sub-1 kg batches matter. the 1 kg minimum gives you sampling headroom without wasting expensive competition lots, and 9 kg maximizes let you build weekend inventory or handle small wholesale accounts. gas modulation and profile logging help with repeatability once you've dialed profiles. the closed combustion chamber design keeps smoke out of customer areas if you're roasting in a cafe. trade-off is the narrow sweet spot: if you're regularly running 8 or 9 kg batches you'll outgrow it fast, and if you're mostly doing 1 to 3 kg runs you're paying for capacity you don't use. it's best for roasters doing 50 to 200 kg weekly with diverse SKUs and retail focus, where batch flexibility matters more than raw throughput.
what it does well
- 1 kg minimum batch handles sample roasting and microlot dialing economically
- 9 kg maximum supports weekend production and small wholesale runs
- profile logging and modulating gas burner aid consistency across varied origins
- negative pressure combustion works for cafe or shared retail roasting
where it stops short
- outgrow 9 kg capacity quickly if wholesale grows past 200 kg weekly
- paying for 9 kg platform when regularly roasting 1 to 3 kg batches
- limited north american dealer and service infrastructure
- no published dimensions or weight makes installation planning difficult
