The present invention relates to an apparatus for roasting green beans. The apparatus for roasting green beans according to an embodiment of the present invention comprises: a roasting kettle in which a roasting portion responsible for roasting green beans is formed; a heating member for heating the roasting kettle during roasting, the heating member being embedded in a heating hole formed in the roasting kettle and integrated with the roasting kettle; and a stirring device which is rotatably mounted inside the roasting kettle and stirs green beans during roasting. By providing heating to the roasting kettle during green bean roasting, the heating member embedded in the heating hole formed in the roasting kettle therefore enables more efficient roasting, resulting in a great decrease in the roasting time of green beans.

A process for treating gaseous effluents developed in a coffee roasting installation making it possible to treat gaseous effluents developed in a coffee roasting installation, in which the effluents are passed through an oxidative catalytic converter. Within the catalytic converter use is made of a catalyst selected from the group including: a) a catalyst including a porous faujasite support containing copper oxide nanoparticles in a quantity of between 2% and 7% of the total weight of the catalyst; b) a catalyst including a porous -alumina support containing copper oxide nanoparticles in a quantity of between 2% and 7% of the total weight of the catalyst; and c) a catalyst including a mesoporous zeolite or silica support containing iron nanoparticles in a quantity of between 2% and 7% of the total weight of the catalyst.

A coffee bean roasting-degree distribution measuring device includes a housing, a micro-processing unit, an image-capturing unit, a light-emitting unit, and a displaying unit. The housing has a first end and a second end opposite the first end with an accommodating space existing between the first end and the second end. The second end is disposed to surround a group of coffee beans under measurement. The micro-processing unit and the image-capturing unit are disposed inside the accommodating space and electrically connected to each other. The light-emitting unit is disposed inside the accommodating space and includes at least one light emitter and a circuit board electrically connected to the light emitter. The circuit board is further electrically connected to the micro-processing unit and each of the light emitter has a light emitting port facing toward the second end. The display unit is disposed on the first end and electrically connected to the micro-processing unit to display a measured roasting-degree distribution curve.

Disclosed is a coffee bean temperature detection device, including an accommodation tube, with two opposite openings, and the opening facing the bean in use is a first opening, and the other opening facing away from the bean is a second opening; a fixing element is fixedly arranged in the accommodation tube but does not contact the accommodation tube; a non-contact thermometer is located in the accommodation tube and fixedly arranged on a surface of the fixing element facing the first opening, with the non-contact thermometer facing the first opening and not in contact with the accommodation tube; and a blowing device is fixedly arranged at end of the second opening, and the blowing device blows in a direction towards the non-contact thermometer.

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.

An apparatus, system and method for changing the positional orientations of peppers or other individual food product items or pieces on an open conveyor belt as the product items or pieces are being continuously conveyed through an apparatus for flame roasting, cooking, searing or otherwise treating the product. The open conveyor belt carries the peppers or other products over one or more air knives which are installed in the apparatus beneath the open conveyor belt for rolling, rotating, and/or momentarily lifting the product items or pieces.

A method and system for preparing coffee includes roasting green coffee beans, thereby resulting in roasted coffee beans; grinding the roasted coffee beans, thereby resulting ground coffee; and degassing carbon dioxide from the ground coffee.

Apparatus for roasting coffee beans, the apparatus comprising: a casing that defines an internal void, a baffle for dividing said internal void into first and second zones that are in fluid communication with one another; a heater for heating air to temperatures suitable for roasting coffee beans, said heater being located in said second zone; a control system for controlling the apparatus; said control system being located in said first zone; and a fan operable to draw ambient air into said first zone and drive said air from said first zone past said baffle into said second zone for heating by said heater, the arrangement being such that in use said first zone is cooler than said second zone.

An apparatus for drying, roasting, and cooling loose products includes a housing; a roaster drum configured to receive the loose products; a heat source disposed in an interior of a heat exchange chamber and configured to heat a gas circulated through the housing; a gas distribution grid reversibly coupled to a bottom of the roaster drum; a tilting hatch disposed below the gas distribution grid and configured to rotate between a raised position when the gas distribution grid is coupled to the bottom of the roaster drum and a lowered position when the gas distribution grid is uncoupled from the bottom of the roaster drum; an insulated channel configured to allow air to circulate from the heat exchange chamber to the gas distribution grid; and a cooling table configured to receive and cool the loose products, wherein the tilting hatch in the lowered position allows the loose products to slide down the gas distribution grid.

A coffee roasting apparatus is disclosed that comprises a compartment for holding coffee beans; a roasting element for roasting the coffee beans in said compartment; a controller for controlling the roasting element; and a sensor for monitoring a total amount of volatile organic compounds (VOCs) released by said coffee beans during roasting and providing the controller with an indication of said monitored amount. The controller is adapted to receive an indication of the total weight of the coffee beans in the compartment and control the roasting element as a function of the indication of the monitored total amount and the indication of the total weight, said function defining the total VOC release characteristics of said coffee beans during roasting. A coffee brewing apparatus and coffee roasting method are also disclosed.
