Abstract: A roaster for roasting coffee beans includes a roasting chamber having a top and a bottom. A cover is seated on the top of the roasting chamber and a bottom of the roasting chamber is seated on a base. A hot air supply is provided in the base for supplying hot airflow into the roasting chamber for heating the coffee beans. At least one air opening is formed on the bottom for enabling the airflow to enter the roasting chamber. A wind tunnel is provided over the air opening for increasing the speed of the airflow in the roasting chamber as the airflow passes through the wind tunnel.

Abstract: An electric cooker includes a base, a housing supported on the base and having an opening, and a power head configured to be removably attached to the housing at the opening. The power head includes a heating unit for generating and directing heat into the housing. At least one land piece is provided on the power head for securing the power head onto the housing, and at least one corresponding tab piece is provided on the housing and is configured to matingly engage the land piece for removably attaching the power head onto the housing. A locking device provided on the power head proximate the land piece prevents the land piece and the tab piece from disengaging from a temperature increase inside the housing.

Abstract: A combined rotisserie and convection oven includes a cooking chamber having a first end and a second end. A fan is in fluid communication with the cooking chamber for creating an airflow in the cooking chamber, and a removable spit is rotatably suspended between the first and second ends of the cooking chamber. A heating element for providing the cooking temperature is provided in the cooking chamber, and is movable to a plurality of positions within the cooking chamber.

Abstract: A roaster for roasting coffee beans includes a roasting chamber having a top and a bottom for holding coffee beans when the beans are being roasted, a cover seated on the top of the roasting chamber and a base on which the bottom of the roasting chamber is seated. A device is provided in the base for supplying airflow into the roasting chamber. A controller controls the airflow supplying device to generate a roasting temperature inside the roasting chamber that tracks a predetermined temperature curve. The temperature curve includes a first stage in which the roasting temperature is set to a first predetermined level for a first predetermined time period, and a second stage in which the roasting temperature is set to a second predetermined level that is higher than the first predetermined level.

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).

Abstract: The present invention relates to an apparatus for roasting raw coffee beans which apparatus can instantly roast a small quantity of raw coffee beans according to personal taste and provide a unique taste and fragrance of coffee, and in particular to an apparatus suitable for home use. The apparatus has a roasting vessel for containing raw coffee beans to be roasted. A plurality of air openings are provided for creating a whirling vertical motion to a heated airstream ascending therethrough, whereby the raw beans are roasted and also caused to have their hulls separated and caused to ascend upwardly with the airstream to a hull-receiving vessel.
