Toper TKM-SX 180 Gas Coffee Roaster for Dark Roasts

If you’re running a high-volume specialty coffee operation and need consistent, high-capacity dark roasts with industrial reliability, choosing the right roaster is non-negotiable. Whether you're aiming for deep chocolatey body or intense caramelized notes, your equipment has to match your roast profile goals — especially when working with 180-kilogram batches.

The Toper TKM-SX 180 gas coffee roaster is built for exactly that: it roasts 180kg of green coffee per batch, achieving a light roast in just 10 minutes or a full dark roast in 15. At light levels, it processes up to 1080kg per hour; for darker profiles, output is 720kg hourly. That’s serious throughput for serious roasters.

What Is the Toper TKM-SX 180?

The Toper TKM-SX 180 is a commercial gas-fired coffee roaster with a single-batch capacity of 180 kilograms of raw coffee beans. Designed for volume and versatility, it supports multiple roasting styles including conduction-based, semi-hot-air (semi-direct flame), and full hot-air systems. This makes it suitable for everything from light filter roasts to dense, heavy dark roasts.

How Fast Can It Roast?

Roasting time and throughput vary significantly with roast level:

• Light roast: 10-minute batch duration — up to 1080kg roasted per hour
• Dark roast: 15-minute batch duration — up to 720kg roasted per hour

This means the machine is optimized for both efficiency and control, allowing roasters to scale production while adjusting for roast depth. The ability to shift between roast profiles without compromising throughput is a key advantage for high-volume specialty operations.

How Does the Roasting System Work?

The TKM-SX 180 uses a hybrid roasting mechanism:

• Conduction-based heat transfer through direct drum contact
• Semi-hot-air (semi-direct flame) system for enhanced airflow and heat distribution
• Optional full hot-air mode for more even roasting

The machine is powered by bucket-style gas — specifically supporting liquefied petroleum gas (LPG), natural gas, or diesel — giving flexibility based on local fuel availability. The burner system feeds controlled heat into the drum environment, enabling the full range of roast profiles from City+ to French or Italian styles.

What Are the Technical Specs?

Here are the core specifications of the Toper TKM-SX 180:

• Batch size: 180kg green coffee
• Dimensions: 520cm (L) × 385cm (W) × 300cm (H)
• Weight: 3200kg
• Voltage: 110–220–380V, 50–60Hz (single- or three-phase)
• Power consumption: 8.35kW / 19.49A
• Motors: 5 total
• Color options: Black, red, or custom
• Exterior finish: Chrome plating, brass, or copper accents

These specs make the machine suitable for large-scale roasting facilities. Its size, power draw, and fuel compatibility ensure it fits standard industrial layouts while offering customization for branding or facility aesthetics.

Why Choose a Semi-Hot-Air or Direct-Fire Roaster for Dark Roasts?

Dark roasts rely heavily on Maillard reaction development and the release of complex aromatic compounds — many of which emerge around the 15-minute mark. The TKM-SX 180’s semi-hot-air and direct-fire modes deliver the intense, even heat needed to push beans into deeper roast levels while minimizing surface scorching and maximizing flavor development. These modes allow precise control over airflow and drum temperature, crucial for developing classic dark roast notes like caramel, nuts, dark chocolate, and toast.

Frequently Asked Questions

What batch size does the Toper TKM-SX 180 handle?

The Toper TKM-SX 180 handles one batch of 180 kilograms of green coffee beans at a time. This makes it ideal for medium- to large-scale commercial roasting operations needing high-volume output.

How long does it take to roast light vs dark coffee on the TKM-SX 180?

A light roast takes approximately 10 minutes per batch, while a dark roast requires about 15 minutes per batch on the Toper TKM-SX 180. Roast time directly affects hourly throughput.

What’s the hourly production rate for light and dark roasts?

For light roasts, the TKM-SX 180 can produce up to 1080 kilograms per hour. For dark roasts, the output is lower — up to 720 kilograms per hour — due to longer roast times.

What fuel types can the Toper TKM-SX 180 use?

The roaster is compatible with bucket-style gas fuels including liquefied petroleum gas (LPG), natural gas, and diesel. This gives roasters flexibility based on regional fuel availability and cost.

What voltages and phases does the machine support?

The Toper TKM-SX 180 operates on voltages from 110 to 380V, with frequencies of 50–60Hz. It can be wired for either single-phase or three-phase electrical systems, suiting various global power standards.

Does the machine come in different colors or finishes?

Yes. The TKM-SX 180 is available in black or red as standard, and custom color options are offered. The exterior also features finishes such as chrome plating, brass, or copper for a tailored industrial look.
