A coffee roasting system is provided. The system includes a roaster mechanism with a container for accommodating coffee beans. The system also includes a heat source configured to produce heat. The system further includes a heat transfer mechanism comprising a first interface which can be coupled with the heat source and a second interface which can be coupled with the roaster mechanism. The second interface is configured to allow the heat transfer mechanism to be disengaged from the roaster mechanism. In addition, the system includes a control module coupled to the heat source and roaster mechanism and configured to control the heat source and roaster mechanism.

Disclosed is a roaster/roasting machine for roasting an edible plant such as coffee beans. This roaster/roasting machine comprises a roasting chamber for containing a substance to be roasted, the roasting chamber being made of a carbon material (graphite, CC composite, etc.). Thus, the roaster/roasting machine can utilize far-infrared rays for roasting with a simple structure. A roaster comprising an open top container body and a closure member may be used for home roasting. A roasting machine comprising a drum-shaped roasting chamber may be a professional roasting machine. The present invention can be applied to any of a direct-, semi-hot air-, and hot air-heating type roaster/roasting machine. Also disclosed is a method for roasting beans such as coffee beans, the method comprising contacting beans with a heated graphite.

A fluidized electric coffee roaster includes a housing; a fluidizing chamber having a predetermined volume into which raw coffee beans are introduced, discharged, and roasted; a heating unit communicating with a lower end of the fluidizing chamber; an air supply unit connected to the heating unit and supplying external air inside the housing to the heating unit; a raw coffee bean injecting unit connected to an upper end of the fluidizing chamber and allowing raw coffee beans to be injected into the fluidizing chamber from an outside; and a coffee discharging unit connected to a lower end of the fluidizing chamber and allowing roasted coffee to be discharged, wherein air heated by the heating unit is supplied to the lower end of the fluidizing chamber and is discharged to an upper end of the fluidizing chamber so that the raw coffee beans are circulated from a lower part of the fluidizing chamber to an upper part of the fluidizing chamber and roasted.

Disclosed is a vacuum roaster including a chamber, a door cap formed on one side of the chamber so as to be opened or closed, a vacuum cap formed on an opposite side of the chamber, a basket spaced apart from an inner circumferential surface of the chamber, and including a basket door that is opened or closed for introduction and discharge of an object to be processed, a vacuum adjustment device for adjusting a vacuum state inside the chamber, a drive motor connected to the basket via a shaft for rotating the basket, and a heater provided inside the chamber so as to be spaced apart from the basket.

A device for roasting beans which is significantly easier to install and place in a bean-roasting machine includes a chassis, a bean roasting tube, and a driving member. The chassis defines an accommodating cavity and a receiving hole communicating with the accommodating cavity. The bean roasting tube includes a rotating member and a chamber. The rotating member is detachably connected to the chassis. The chamber includes a first end plate, a second end plate opposite to the first end plate, and a bearing piece fixedly connected between the first end plate and the second end plate. The second end plate faces the receiving hole and is rotatably connected to the rotating member. The driving member is fixed to the first end plate and movable to drive the chamber to rotate in the accommodating cavity.

A roaster and method for roasting coffee beans is provided, and includes a drum that extends axially along a rotational axis, and a motor that rotates the drum about the rotational axis. A bean inlet port is located adjacent to a first end of the drum, and receives coffee beans to be introduced to the drum for roasting. A heater generates a heated gas by elevating a temperature of a gas to at least a roasting temperature, and a nozzle directs the heated gas generally toward the coffee beans within the drum while the drum is rotated by the motor. A collection bin adjacent to a second end of the drum collects the coffee beans exiting the drum after the coffee beans are roasted by the heated gas while traveling through the drum between the inlet port and the collection bin.
