Durable Drum Structure

The drum is the most important part of the coffee roaster, WK-12 drum is made of food level 304 stainless steel, single-layer drum thickness is 8 mm. The brackets are thick enough welded inside the drum which keeps the drum more stable to last its service life for many years to come. The special mixing blades design makes coffee beans inside the drum well-mixed. Single-layer drum and double-walled drum for options, customers could choose what they prefer.

Gas Burner can be converted

WK gas burner made in high quality and produces strong fire flame to fit different roasting requirements,  fire flame can be adjusted to weak or strong by adjusting the gas gauge knob.  It is can be converted from LPG ( NG) to NG (LPG) by replacing nozzles.  wherever you want to use LPG or move to a place for NG, WK gas roasters follow up you in roasting anywhere.

Cooling Fan, Drum Speed Control, Data logger USB Port, Aviation socket

Cooling Fan : Our WK-6 coffee roaster keeps the electric cabinet away from the drum which avoids overheats from the drum results in shortening the electric parts service life. Plus we installed a large cooling fan to help electric parts dissipate heat, maximumly keep electric parts work in good condition.

Drum Speed Control: If you are not satisfied with constant drum roasting, and you want to develop more tastes from roasted beans, you could try to roast the coffee beans under different drum speeds, that will bring you more surprise.
Adjust Range: 0-100RPM

Data logger USB port: connect to your computer and open Artisan
software to start recording your roasting profiles.
Aviation socket: A button set up close to it which avoids any electric
shock, every detail ensures safety.
