Toper TKM-SX 5kg Coffee Roaster: Electric & Gas Options

If you’re looking to roast 5-kilo batches of specialty coffee with control over airflow and heat application, you’ve likely considered a mid-sized semi-hot-air roaster. But with options for electric or gas power, different batch times, and varying throughput depending on roast level, how do you know which setup fits your workflow? The Toper TKM-SX 5kg offers flexibility for both small-scale production and serious single-origin development.

The Toper TKM-SX 5kg roaster handles 5kg green coffee batches, roasting light profiles in around 10 minutes and dark roasts in roughly 15 minutes. It achieves output rates of 30kg per hour for light roasts and 20kg per hour for dark roasts, using a semi-hot-air (semi-direct flame) system powered either by electric heating rods or gas (LPG or natural gas).

What Is the Toper TKM-SX 5kg?

The Toper TKM-SX 5kg is a semi-hot-air coffee roaster designed for boutique and specialty roasters wanting medium-capacity production with flexible energy sources. It’s built to roast up to 5 kilograms of green coffee per batch using a combination of conductive drum heating and forced air circulation—commonly referred to as “semi-direct” or “semi-hot-air” roasting. This allows for greater control over the Maillard reaction and development time compared to full-drum conduction machines.

Capacity & Output: How Much Can It Roast?

This machine processes a single batch of 5kg green coffee. Roasting times vary with profile: light roasts typically take about 10 minutes, while darker roasts extend closer to 15 minutes. Production throughput differs by roast level: up to 30kg of coffee can be roasted per hour when aiming for lighter profiles, and around 20kg per hour for darker roasts. These numbers reflect real-world output based on the time and heat application needed per batch.

Power & Configuration Options

The TKM-SX 5kg gives you a choice between electric or gas heating. Electric models use heating rods and operate on voltages of 110V, 220V, or 380V, with frequencies of 50-60Hz, supporting both single-phase and three-phase power. The electrical load is 1.48 kilowatts with a current draw of 16.8 amps. Gas-powered versions run on bottled LPG or natural gas . The roaster also comes equipped with four motors to handle drum rotation, airflow, and other mechanical functions. Dimensions are 150cm (L) × 120cm (W) × 170cm (H), and it weighs 320kg.

Design & Customization

The roaster’s body is available in black, red, or made-to-order colours. Its exterior finish can include chrome plating, brass, or copper elements, allowing for a bespoke look that fits into different roastery environments. These aesthetic choices let roasters match the machine to their brand or workspace design.
