Hot Air Pressure Gauge

Controlling airflow is very important during the roast, Normally, 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 the 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 precise.

High-Performance Burner

Our team works hard for developing high-performance heating burner. It is easy to ignite the fire on the burner and keep it strong to heat the drum, plus the durable
insulation layer around the drum, you can maximize use the heats only to beans which saves the fuel.

Large Maintenance  Access

Large Maintenance Access

WK-3 is designed with large maintenance access which is easy to clean and replace parts. If you need to clean or replace the gas burner, you just need to screw off the little bolts on the maintenance access door to finish it. This is a great improvement from our previous model.

Cooling Tray and Cooling Tray Access

Cooling Tray: To get roasted coffee beans cool down in a faster time, we designed a cooling tray diameter at 500mm, a large cooling tray works with a powerful cooling tray motor to get roasted beans cool down within 2 minutes. And it’s made of fully 304 stainless steel without any painting. (All the parts on the machine contact beans directly, we do not use any painting). Cooling tray with cover and Cooling tray without cover for options. 

Cooling Tray Access: Cooling tray access is designed by a latch door which is easy to clean up all the space under the cooling tray with one hand.
