Abstract
An improved apparatus for roasting raw coffee beans includes a main housing (10) having an air inlet (24). A blower assembly (18,20,22) is disposed within the housing (10) and is in fluid communication with the inlet (24). The blower assembly has a discharge location (32) whereat an electric heater (34) is located. A coffee bean receiving vessel (12) is removably mounted on the main housing (10) and in turn, a hull collector (14) disposed on the vessel (12). A control (FIG. 3), including a sensor (38,136), is located in the air stream upstream of the inlet (56,58) to the vessel (12) and downstream of the electric heating element (34).
