The invention concerns a method to determine the recipe Rym for roasting a quantity m of a type Cy coffee beans in a particular type of roasting apparatus, said recipe Rym providing setpoints (Tym@ti; ti), wherein the method comprises the steps of:—getting access to: ⋅a rule to calculate the roasting recipe adapted to the roasting of a quantity of beans, said quantity being comprised in a list of pre-determined quantities (M, M±Δx), from any pre-existing roasting recipe adapted to the roasting of another quantity of beans in said particular type of roasting apparatus, said another quantity being comprised in the list of pre-determined quantities (M, M±Δx), and to at least one pre-determined original roasting recipe RyMoriginal adapted to the roasting of one original pre-determined quantity Moriginal of the type Cy coffee beans, and—based on the comparison between m, the accessible original pre-determined quantity Moriginal and the accessible pre-determined quantities of the list (M, M±Δx), determining the roasting recipe Rym to be applied on said quantity m of coffee beans.

A coffee bean roasting machine includes a roast chamber for accommodating coffee beans, a hot blast device for supplying hot or cool air to the roast chamber, and a collection chamber for collecting the outer skins of coffee beans. The collection chamber is in communication with the roast chamber and the bottom of the roast chamber includes a first bean outlet where a chamber door is set for open and close. Coffee beans can be easily taken out from the coffee bean roasting machine, without lifting up the whole roasting machine and tipping it over.

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.

The invention concerns a method of roasting coffee beans with a roasting apparatus (X), said roasting apparatus comprising a control system (80) configured to control the heating device (2) and to reproduce roasting recipes, said control implementing a feedback loop regulation based on the temperature Treg measured by the at least one temperature probe (5), wherein, before roasting coffee beans by reproducing coffee beans roasting recipes defined with one specific master roasting apparatus (M), the feedback loop regulation is adjusted, said operation of adjustment comprising the step applying pre-determined correction KC to the feedback loop regulation.

The invention relates to a roasting and processing apparatus for coffee beans comprising a roasting device (50) and an associated coffee processing device (60, 70); the roasting device (50) being configured for receiving coffee beans of a certain type that will be roasted, the roasting device comprising reading means (53) to identify the characteristics of the coffee beans dispensed to it, the roasting device (50) further comprising a control unit configuring the roasting profile of the beans according to the characteristics retrieved from the reading means (53) and/or from the characteristics of the beans in a database (51) in this control unit and/or according to the user input; the roasted coffee beans being transferred into a coffee processing device (60, 70) for beverage preparation, the roasting device (50) comprising a data transfer function to communicate product parameters of the roasted coffee beans of a certain type to the coffee processing device (60, 70); the coffee processing device (60, 70) receiving roasted coffee beans of one or more types from the roasting device (50); the coffee processing device comprising a data reader (62,72) to obtain the information of the product parameters of the roasted coffee beans; the coffee processing device (60, 70) further comprising a control unit configured to adapt the processing parameters used for the beverage preparation as a function of the product parameters of the roasted coffee beans. Furthermore, the invention relates to a method for roasting and processing coffee beans using a roasting and processing apparatus as the one described. Also, the invention relates to the use of a roasting and processing apparatus as the one described for delivering a coffee beverage of a certain type and/or a certain quantity of grinded coffee.

The present disclosure relates to a roasting apparatus and a method of controlling the roasting apparatus, and more particularly, to a roasting apparatus for roasting objects while stirring the objects in a roasting chamber, and a method of controlling the roasting apparatus. An roasting apparatus for heating objects according to the present disclosure includes a roasting chamber part which includes: a cylindrical roasting chamber that extends in a vertical direction and has an internal space in which the objects are stirred; and a rotary stirring part that rotates to stir the objects received in the roasting chamber and rotates about a stirring axis defined in the vertical direction. The roasting apparatus further includes heat source parts which supply heat to the roasting chamber part.

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.

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.

The invention concerns an apparatus (10) for roasting coffee beans comprising : - a roasting chamber (1), - an air driver (8) configured to drive air inside the roasting chamber through the bottom opening of said chamber, - a heater (9) configured to heat air driven inside the roasting chamber, - a chaff collector (3) connected to the roasting chamber through a first channel (31), - at least one beans collector (4) for fully roasted beans connected to the roasting chamber through at least one second channel (41), wherein said apparatus comprises a distributing device (5) configured to open either the first channel to the chaff collector (3) only or to the at least one second channel to the at least one beans collector only.
