Toper TKM-SX 5kg Gas and Electric Coffee Roaster Specs

If you’re looking to scale up your coffee roasting operation with precision and flexibility, choosing the right machine matters. Whether you roast electrically or with gas, batch size, roast time, and heat delivery method all affect your workflow and cup profile. The right 5kg-capacity roaster can handle both light and dark roasts efficiently without compromising quality.

The Toper TKM-SX 5kg coffee roaster roasts 5kg of green coffee per batch, taking roughly 10 minutes for light roasts and 15 minutes for dark roasts. It offers production speeds of 30kg/h for light roasts and 20kg/h for dark roasts, with options for electric or gas heating and a semi-hot air (semi-direct flame) system.

Batch Capacity and Roast Times

The Toper TKM-SX 5kg is built for small-batch specialty roasting. Each batch holds 5kg of raw coffee beans. For lighter roasts, typical roast times are around 10 minutes. Darker roasts take approximately 15 minutes. These timings align with standard specialty practices where development time and heat application determine roast level.

Production Output Rates

This machine achieves different hourly outputs depending on roast style. For lighter roasts, it processes up to 30kg per hour. When running darker roasts, the output drops to 20kg per hour. These rates reflect the extended dwell time and heat needed for darker profiles, balancing productivity with thermal control.

Heating System and Roast Method

The TKM-SX 5kg offers two heating options: electric or gas. Electric models use heating rods, while gas-powered versions run on bottled propane or natural gas. The roaster employs a combination of conductive heat transfer and semi-hot air (also called semi-direct flame or semi-convective) roasting. This hybrid approach provides both radiant heat and airflow control critical for developing complex flavours during the Maillard reaction and first crack.

Power and Mechanical Specs

The electrical version requires a voltage range of 110–220–380V, at 50–60Hz, supporting both single-phase and three-phase power. Total power consumption is 1.48 kilowatts, drawing 16.8 amps. The roaster includes four motors to drive drum rotation, airflow, and cooling systems. These components ensure consistent heat distribution and bean agitation throughout the roast cycle.

Physical Dimensions and Build

The Toper TKM-SX 5kg measures 150cm in length, 120cm in width, and 170cm in height. It weighs 320kg, reflecting its robust steel construction. The roaster is available in black, red, or custom colours. Its exterior finish includes options for chrome plating, brass, and copper detailing, blending industrial utility with a classic aesthetic.

Frequently Asked Questions

What batch size does the Toper TKM-SX 5kg roast?

The Toper TKM-SX 5kg roasts exactly 5kg of green coffee beans per batch. This capacity is ideal for small to medium specialty roasters balancing output with quality control.

How long does it take to roast on this machine?

Light roasts typically take about 10 minutes per batch, while dark roasts require around 15 minutes. These times are standard for achieving the desired roast profiles without over- or under-developing the beans.

What’s the difference between electric and gas versions?

The electric model uses heating rods, while the gas version runs on bottled propane or natural gas. Both offer the same 5kg batch capacity and semi-hot air roasting method, but fuel source affects setup, ventilation, and operating cost.

How much coffee can it produce per hour?

For light roasts, the output is 30kg per hour. For dark roasts, it’s 20kg per hour. These rates depend on the longer roast times and heat retention needed for darker profiles.

Does the Toper TKM-SX 5kg use convection or drum heat?

It uses a semi-hot air (semi-direct flame) system, combining radiant drum heat with airflow. This hybrid method supports even heat application and better control over the roast profile.

What colours and finishes are available?

The roaster comes in black, red, or custom colours, with optional finishes including chrome, brass, and copper. These choices allow roasters to match their equipment to their roastery’s style.
