GOOD quality coffee roaster machines gas burner 

There are three ways to transfer heat, Radiation, Convection, Conduction and their thermal efficiency decrease in turn. Most Equipment is mainly by convection to heat air first and then, the heated air transfer to object. Heat loss is big. But, differently, infrared gas burner heat object directly by radiation and transfer rate will be much higher, usually it can save 10~20% gas energy and cost.
