Solid drum and Perforated drum

We creatively designed the machine structure compatible with two roasting types: half-hot air roasting, and full direct-fire roasting by quickly replacing the solid drum and perforated drum.

Solid drum for half-hot air roasting, and perforated drum for full direct-fire roasting.

Drum still adopts the latest far-infrared shaft-less design, the raw material is  carbon steel alloy and it is coated by far-infrared ceramic coating. which can keep the each bean inside the drum gets uniform heats during roasting,
also, it keeps a clean drum inside and lowers the machine noise.

Hot Air Pressure Gauge

Controlling airflow is very important during roast. Normally,
for WS-500, we control airflow is only by manual damper.
But once you forget to clean up the exhaust pipe and exhaust fan motor in time, the dust and chaff may block the pipe or motor, or if you meet the bad weather (like strong wind, heavy
rain etc.), you may not get exact pressure value by manual damper.
Then the hot air pressure gauge can help you get the real airflow pressure value in any condition, that makes your roast more precisely.

High Performance Burner

WS-500 adopts an improved high-performance direct-fire row burner to fix the flaws of controllability and stability by
the previous normal burner. Fire flame is powerful to provide the even heats to drum. Temperature rise can be reached 16℃/minute, the first crack can be finished within 8 minutes.
