The TP-BRO3 Compact Coffee Roaster 3KG is a gas-fired roasting machine that processes 3 kg of green coffee per batch, with a roast time of 15-20 minutes per batch. Model TP-BRO3 sits above the TP-BRO1 in the compact roaster line, bringing the same air-cushion drum design and purpose-built gas burner system to a slightly larger batch size for cafés and small roasteries ready to increase output.
What Is the TP-BRO3 Compact Coffee Roaster 3KG?
The TP-BRO3 is a 3 kg-class compact coffee roaster designed for specialty cafés, small roastery operations, and businesses that have outgrown a 1 kg sample roaster but don’t yet need industrial-scale equipment. It uses a heat-resistant drum, a hybrid direct/indirect heating method, and a fast cooling system, in a compact steel frame with an easy-to-operate control cabinet.

Key Features of the TP-BRO3 Coffee Roaster
1. Air-Cushion Roasting Drum
The air-cushion drum promotes even heat transfer around the beans. Combined with a specially designed agitator-blade system, it minimizes scorching and tipping, producing roasted beans with a bright, glossy finish. The drum is made from high heat-resistant material to extend service life and is available in single-layer or double-layer heating.
2. Purpose-Built Gas Burner System
The burner system is engineered specifically for coffee roasting, so roasters can shape aroma development, acidity, bitterness and aftertaste. It also keeps gases generated during roasting, such as NOx and COx, and other impurities to a minimum.
Burner highlights:
- Imported burners from Taiwan, Italy, Europe and South Korea for high durability
- Complete gas combustion with no residual gas smell
- Fast aroma development during roasting
- Gas-saving hybrid heating (50% direct, 50% indirect)
3. Fast, Effective Cooling
The stainless steel 304 cooling tray and cooling fan cool beans quickly after roasting to prevent carry-over roasting inside the bean. The system also collects chaff and smoke and vents them out of the roasting room. The tray is driven by a three-phase LiMing gear motor, and the cooling fan is from Trantechno.
4. Easy Operation and Precise Temperature Control
Sensors and a temperature control system are built in, and the compact control cabinet sits beside the machine body. Temperature sensors inside the drum give real-time readings, helping roasters repeat profiles consistently as they scale up from sample batches.
5. Quality Branded Components
- Toshiba drum gear motor
- Trantechno heat and cooling fans (Italy)
- LiMing cooling-tray motor
- LS magnetic contactors
- Idec power switch, push buttons, relays and emergency stop
