Compared to air roasters, drum roasters roast more slowly, more like commercial machines and DIY manual methods. Roast times will be in the range of 14 to 20 minutes. These machines offer great control over the time, temperature and roasting profiles. Generally the more expensive the machine is, the more features and control you get.

Depending on the machine, these machines will produce about 8 to 12 oz of roasted coffee per batch. Drum roasters tend to develop the body of a coffee while maintaining the brightness. They are also more durable then air roasters, as they do not require the high fan speeds that small air roasters do. Replacement parts are available from the manufacturers as well.
