The present invention relates to a coffee roasting device, and may comprise: a body; a rotating unit rotatably fastened/fixed to the upper portion of the body, a part of one side surface of the rotating unit being incised in the longitudinal direction, thereby forming an entrance/exit, and coffee beans being contained inside the rotating unit via the entrance/exit; a heating unit positioned inside the rotating unit and supplied with external power, thereby generating heat; a driving unit positioned on one side of the rotating unit, the driving unit providing the rotating unit with rotating power; and a partition attached/fixed to the inner surface of the rotating unit so as to prevent the coffee beans from being discharged to the outside via the entrance/exit.

A roasting and glazing apparatus comprising a housing, a bowl assembly having a bowl support and a roaster bowl, an agitator rotatably mounted within the roaster bowl, a heater to heat the roaster bowl, and a cantilever arm disposed external to the housing. The cantilever arm, when moved, moves the roaster bowl between fully lowered and fully raised positions. A first piston is coupled to the bowl support and provides, when engaged, a counterforce to the weight of the bowl assembly. The first piston is engaged at least during the raising of the roaster bowl. A second piston provides a counterforce during the lowering of the roaster bowl from a partially lowered position to the fully towered position. The second piston is not engaged during lowering of the roaster howl from the fully raised position to the partially lowered position. After producing roasted and glazed nuts using the apparatus, the roaster bowl is raised to facilitate removal of the roasted and glazed nuts, and then the roaster bowl is lowered. After the roaster bowl is lowered to the partially lowered position, the engagement of the second piston results in additional downward force to further lower the roaster bowl thus preventing injury or damage during the final lowering of the roaster howl into its fully lowered position.

A drum roaster for roasting beans. The drum roaster includes a housing arrangement having as operating elements at least a bean inlet arrangement and a bean outlet arrangement, a roasting drum for receiving the beans, a drive device which rotates the roasting drum, a heating device which heats the beans, and an insulation element which provides a thermal insulation. At least the bean outlet arrangement is arranged at a front side of the housing arrangement. The roasting drum is rotatably mounted in the housing arrangement. The insulation element is arranged at the front side in a region of the bean outlet arrangement.

A method of producing roasted and glazed nuts includes the steps of providing a roaster apparatus having a roaster bowl, placing water and a mixture of nuts and sugar in the roaster bowl, mixing the water and the mixture, heating the roaster bowl while mixing to produce roasted and sugar coated nuts, adding water to the roaster bowl to produce roasted and glazed nuts, and lifting a cantilever arm coupled to the roaster's housing to raise the roaster bowl from a fully lowered position to a raised position. A first piston coupled to the bowl support is engaged during the raising of the roaster bowl to provide a counterforce to the bowl assembly's weight. The method further includes removing the roasted and glazed nuts from the roaster bowl when in the raised position, lowering the cantilever arm to lower the roaster bowl from the raised position to a partially lowered position, and then lowering the cantilever arm to lower the roaster bowl to the fully lowered position. A second piston is engaged during the lowering of the roaster bowl from the partially lowered position to the fully lowered position to provide an additional counterforce thus preventing injury during the final lowering of the roaster bowl. The second piston is not engaged during the lowering of the roaster bowl from the raised position to the partially lowered position.

An apparatus/method of cleaning a roaster bowl having a pouring lip and a cover (e.g., sugar or other coating is adhered to the bowl, its pouring lip and the cover). Water is added to the roaster bowl and the cover is placed over the roaster bowl. An appropriately sized and located steam vent is disposed between the cover and roaster bowl, adjacent to the bowl's pouring lip. The roaster bowl is heated to boil the water to produce steam that dissolves the sugar adhered to the roaster bowl and to the underside of the cover. Steam exiting the bowl via the vent condenses on the pouring lip to dissolve the sugar that is adhered to the pouring lip, and the sugar-laden steam drips back into the bowl thus cleaning the pouring lip.

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 bean roasting system comprises a roasting drum including (1) a housing enclosing a roasting chamber and having a curved inner surface defined by a curved lower wall, and (2) an air inlet chamber fluidically coupled to the roasting chamber and configured to direct air toward the curved inner surface which redirects the air in a first rotational direction. A distal end of each blade from a plurality of blades is disposed from a axis of rotation toward the curved lower wall by a distance no greater than R. The curved lower wall is spaced at least a distance R+G from the axis of rotation to provide a minimum gap G. The agitator blade set and the directed air are collectively prevents accumulation of beans along the curved lower surface during a roasting process.
