Toper TKM-SX 15 Gas: Specs & Performance for 15kg Batches

If you’re running a production roastery or serious specialty micro-roaster, choosing the right 15kg-capacity coffee roaster matters—not just for volume, but for control, consistency, and workflow efficiency. The right machine needs to handle both light and dark roasts without compromising throughput or thermal performance. So what does a workhorse like the Toper TKM-SX 15 Gas really deliver?

The Toper TKM-SX 15 Gas roasts 15kg of green coffee per batch, with light roasts taking around 10 minutes and dark roasts about 15 minutes. Hourly output hits 90kg for light roasts or 60kg for darker profiles, using a semi-hot-air (semi-direct flame) system powered by either bottled or piped gas.

What Is the Toper TKM-SX 15 Gas?

The TKM-SX 15 Gas is a 15-kilogram-capacity commercial coffee roaster built by Toper, designed for mid- to large-scale specialty roasting operations. It employs a hybrid thermal approach: a combination of conductive heating elements and forced semi-hot-air (also called semi-direct flame) circulation to achieve even heat application across the drum. This makes it suitable for developing nuanced profiles in light roasts while still delivering the punch needed for darker styles.

How Fast Does It Roast?

On light roasts, the TKM-SX 15 Gas completes a batch in approximately 10 minutes, translating to an output of up to 90 kilograms per hour. For darker roasts, which typically require longer development time through the Maillard reaction and first crack phases, roast time extends to roughly 15 minutes—reducing hourly throughput to around 60 kilograms. These timings reflect real-world batch processing speeds under standard production conditions.
