Processes for producing roasted nuts are described herein. The processes include mixing bare nuts with maple syrup to coat the bare nuts with the maple syrup and form coated nuts, placing the coated nuts into a cooking apparatus set at a first temperature for a period of time to form roasted nuts, while the coated nuts are roasting in the cooking apparatus, agitating the coated nuts and removing the roasted nuts from the cooking apparatus.

A heat treatment device suitable for performing heat treatment on a material is provided. The heat treatment device includes a cavity, a microwave generator, and a stirring element. The material is arranged in the cavity. The microwave generator is arranged beside the cavity and is suitable for providing a microwave into the cavity. The stirring element is arranged beside the cavity and is suitable for stirring the material.

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.

Disclosed herein are a roasting apparatus and a method of controlling a roasting apparatus, and more particularly, are a roasting apparatus in which an object is stirred and roasted in a roasting chamber, and a method of controlling the roasting apparatus.

The roasting apparatus for heating an object includes a roasting chamber part which includes a cylindrical roasting chamber, in which an object is stirred and which extends in a vertical direction, and a rotary stirring part rotated to stir the object accommodated in the roasting chamber, wherein the rotary stirring part is rotated about a stirring axis formed in the vertical direction; a casing unit configured to surround the roasting chamber part; a heat source part including a first heat source part configured to provide radiant heat to the roasting chamber part; and a radiant temperature measurement unit configured to measure a temperature of the roasting chamber or the object and a chamber outer space temperature of a chamber outer space between the casing unit and the roasting chamber part on the basis of infrared rays emitted from an inner surface of the roasting chamber part or a surface of the object, which is heated by the heat source part, wherein a preheating operation is performed until the chamber inner temperature of the roasting chamber and the chamber outer space temperature reach a preset reference chamber inner temperature and a preset reference chamber outer space temperature.

A bean roasting system includes a roasting subsystem and an air handling subsystem. The roasting subsystem is configured to receive and to thermally roast a batch of beans. The air handling subsystem is coupled to the roasting subsystem and includes a blower, a cyclone separator, and a heater. The blower is configured to impart air motion. The air passes through the air handling subsystem. The cyclone separator is configured to remove particulates from the air handling subsystem. The heater is configured to heat the air passing through the air handling subsystem. The heater includes heater windings that are incorporated into the cyclone separator.

A bean roasting system includes a roasting drum, an air handling system, a bean cooler, and an air exit subsystem. The air exit subsystem is configured to receive and treat a first fluid stream from the air handling system and a second fluid stream from the bean cooler. The air exit subsystem includes a heat sink and a filter. The heat sink defines two parallel fluid paths including a first fluid path and a second fluid path. The air exit subsystem includes a metal body configured to receive heat from the first fluid path and the second fluid path. The first fluid path is fluidically coupled to receive the first fluid stream from the air handling system. The second fluid path is fluidically coupled to receive the second fluid stream from the bean cooler. The filter is fluidically coupled to the first and second air flow paths.

A bean roasting system includes a roasting subsystem and an air handling subsystem. The roasting subsystem includes a housing, an agitator actuator, an agitator, a bearing and a door. The housing has an inner surface defining an inner chamber for holding a batch of beans during a thermal roasting process. The agitator is coupled to the agitator actuator and includes a central shaft and a blade set mounted to the central shaft. The bearing supports the central shaft and is configured to prevent the blade set from contacting the inner surface of the housing. The door has a transparent window to allow viewing of the thermal roasting process. The air handling system is coupled to the roasting subsystem, includes a blower and heater, and is configured to circulate heated air through the roasting subsystem during the thermal roasting process.

A fluid bed coffee roasting system is disclosed and configured for roasting batches of coffee beans of varying sizes. In at least one embodiment, the system provides a roasting unit configured for roasting a volume of coffee beans, a chaff collection unit positioned and configured for drawing off and capturing any loose chaff released by the coffee beans within the roasting unit, and a cooling unit positioned and configured for receiving and cooling the coffee beans after they are removed from the roasting unit.
