A bean roasting system includes a roasting chamber, a blower, a variable diverter and a controller. The roasting chamber, the blower and the variable diverter each is disposed at least partially within a recirculating gas flow path. The blower is configured to provide a flow stream of gas through the recirculating gas flow path. The variable diverter is configured to split the gas flow path into at least two flow paths including a treated flow path and a bypass flow path. The treated flow path includes a series arrangement of a gas heater and a catalytic converter. The variable diverter is configured to control a percentage of a flow stream of gas that is diverted into the bypass flow path. The controller is configured to activate different predetermined operating modes for the bean roasting system by controlling a state of the variable diverter and a state of the heater.

A roasting and glazing apparatus includes a roaster, an agitator mounted within the roaster bowl for mixing a mixture of nuts and sugar during a roasting or glazing operation, a heater controlled to heat the roaster bowl during the roasting or glazing operation, and a cover removably mounted to the roaster bowl. The cover includes a reservoir for receiving water from a user and restricting water flow from the reservoir into the mixture of nuts and sugar in the roaster bowl. The cover and the roaster bowl together define a vent on a side of the cover opposite the reservoir. The vent is configured to direct steam out of the roaster bowl in a direction away from the reservoir.

A small batch roasting device including a base unit and a roasting chamber unit. The base unit includes a housing, a heating element, a fan, and a support surface. The housing defines an upper end, a lower end, and an isolation chamber open to the upper end. The heating element and the fan are within the housing, with the fan being positioned between the heating element and the lower end. The roasting chamber unit defines a roasting chamber, a leading region and a trailing region terminating at a trailing end. In an assembled state, a portion of the roasting chamber unit is disposed within the isolation chamber and the trailing portion is proximate the heating element. The roasting chamber unit is supported relative to the base unit by an interface with the support surface at a location longitudinally spaced from the trailing end.

A bean roasting system includes a roasting drum, an agitator, and a door. The roasting drum has an inside surface extending from a back end to a front end. The agitator has blades mounted to an axial shaft. The axial shaft has an anterior end portion. The door is mounted rotationally relative to the roasting drum and includes a glass plate and a bearing assembly. The glass plate provides visual access to contents inside the roasting drum when the door is closed. The bearing assembly includes an outer housing and an inner bearing. The outer housing is mounted to the glass plate. The inner bearing defines a receiving hole that receives and supports the anterior end portion of the axial shaft when the door closed.
