A bean roasting system includes a roasting subsystem, a cooling subsystem, an air exit subsystem that is fluidically coupled to the cooling subsystem, and a controller. The cooling subsystem includes an outer housing containing a holding chamber, a cooling platform defining a lower bound of the holding chamber, a vibration actuator coupled to the cooling platform, and a platform actuator coupled to the cooling platform. The controller is configured to operate the air exit subsystem to maintain a flow of air up through the holding chamber, operate the roasting subsystem to transfer a batch of beans from the roasting subsystem to the holding chamber, operate the vibration actuator to vibrate the cooling platform, operate the air exit subsystem and operate the vibration actuator accelerates cooling of the batch of beans, and operate the platform actuator to transport the batch of beans out of the cooling subsystem.

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 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.

Methods, systems, and computer programs for multi-tool additive manufacturing include a method including: slicing a received model into a series of layers; determining one or more separation starting points, each being a location of two adjoining portions of the model that are to be manufactured by respective additive manufacturing robots; and determining an offset for each of the one or more separation starting points in each layer of the series of layers based on a threshold acceptable print time, each offset in a layer determining a seam location in the layer that is different from a seam location in at least one adjacent layer in the series of layers, and seam offsets determined for the series of layers increase an estimated print time, for manufacturing of the series of layers by the two or more additive manufacturing robots, to no more than the threshold acceptable print time.
