Durable Drum Structure

The drum is the most important part of the coffee roaster, WK-30 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 (15mm) 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.
