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 roasting system is provided in a form factor of a countertop roasting device including a blower and a roasting assembly in fluid communication with the blower. The roasting assembly receives air from the blower with a heating element of the roasting assembly producing a heated air stream fed through the roasting assembly. An agitator in the roasting assembly agitates the food product. A food product is received in a container of the roasting assembly, with the heated air stream roasting the food product. The system includes a plurality of sensors and a controller that adjusts operating characteristics of the system based on whether a shell of the food product has cracked during roasting, as determined with the microphone. A waste product from the food product is separated during roasting and collected in a waste collection assembly with a spray bar assisting with smoke suppression.

A drum roaster for roasting beans. The drum roaster includes a housing assembly in which a roasting drum for receiving the beans is rotatably supported, a drive device for rotating the roasting drum, and a heating assembly for heating the beans at least via a heating air. The heating assembly includes an electric heating element for heating a feed air, a suction fan for extracting the heating air out of the roasting drum, and a feed air fan to supply the feed air.

The electric heating element is arranged in a heating tube upstream of the roasting drum as seen in a flow direction of the heating air. The suction fan is arranged downstream of the roasting drum as seen in the flow direction of the heating air. The feed air fan is arranged upstream of the electric heating element as seen in a flow direction of the feed air.

A method and processing technology for preparing baked products from raw materials is disclosed. The method includes at least one baking or roasting step in which the raw materials are processed in the absence of atmospheric air, achieved through a vacuum, vacuum-compensated, or pressurethe latter two employing an inert atmosphere. A sealed rotary roasting drum (or processing compartment) is supplied with pre-heated inert gas while heating and rotating the raw materials, and the inert gas is optionally recycled for reuse. Additional unit operations such as milling, cooling, spraying, extraction, and storage are also performed in the absence of atmospheric air, to preserve product quality and prevent oxidation. Optional steps include cryogenic pre-milling, sweetener addition to generating a torrefacto effect, and supercritical fluid extraction of oils for later incorporation into the baked products. The disclosed technology enables continuous production of baked products with improved aroma, stability, and self-life, by maintaining an oxygen-free environment throughout processing.

A bean roasting machine includes a heater device as a heat source for roasting; and a roasting blower that sends high-pressure air into the heater device and sends the air becoming a high temperature by the heater device into the roasting pot, in which the heater device is disposed directly below the central bottom of the roasting pot, an air blowing outlet of the heater device opens upward and is directly connected to an air intake inlet formed in the central bottom of the roasting pot, and the air intake inlet of the heater device is located on a side surface of the heater device and is directly connected to a blowing port of the roasting blower. Thus, the central bottom of the roasting pot is close proximity to the heater device, and the heater device and the roasting pot are directly connected to each other.

An apparatus includes a receptacle configured to receive a container containing a substance for processing. The container includes a readable tag having processing information associated with the substance. The apparatus also includes a processing chamber operably coupled to the receptacle and configured to receive the substance and process the substance. The apparatus further includes a controller operably coupled to the processing chamber and configured to generate one or more processing instructions based on the processing information in the readable tag and further based on additional processing information received from a remote device. The processing is also configured to process the substance based on the one or more processing instructions.

The invention concerns a method for drying at least one cell of the electrostatic precipitator of a smoke treating unit in a system of a coffee beans roasting apparatus and a smoke treating unit, said method comprising the step of passing hot air through said cell, while said cell is positioned inside the electrostatic precipitator and while said cell is switched off.

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.
