A method of roasting coffee beans with a roasting device positioned in a room, and the roasting device includes a roasting device and a smoke treating unit configured to treat the smoke produced in the roasting device and to prevent the dispense of air contaminants in the room. The method includes introducing coffee beans in the roasting device and heating the coffee beans during a time, and a part of the whole quantity of smoke produced during the time of the step of heating is dispensed in the room without being treated by the smoke treating unit.

Apparatus and method for roasting coffee beans

The invention concerns a system for roasting coffee beans comprising: —a roasting apparatus (), said apparatus producing smoke, and—a smoke treating unit () configured to collect and treat smoke produced by the roasting apparatus, wherein: —the roasting apparatus comprises a smoke outlet (), and—the smoke treating unit comprises: a smoke inlet () configured to cooperate with the smoke outlet of the roasting apparatus, a smoke filtering sub-unit () comprising at least an active carbon filter (), a smoke driver () configured to circulate smoke through the smoke treating unit from the smoke collecting device to an outlet () of the smoke treating unit, wherein the smoke treating unit () comprises an air inlet () configured to mix the smoke produced by the roasting apparatus () with ambient air before the smoke is circulated through the smoke filtering sub-unit ().

System for roasting coffee beans

The invention concerns an apparatus () for roasting coffee beans comprising: —a roasting chamber () presenting a bottom opening (), —an air driver () configured to drive a flow of air inside the roasting chamber through the bottom opening of said chamber, —an electrical heater () positioned below the bottom opening of the chamber configured to heat said flow of air driven to the bottom opening of the roasting chamber, wherein the apparatus comprises a conduit () to drive the flow of hot air from the heater () to the bottom opening () of the roasting chamber, and wherein said conduit () comprises a local transversal constriction (), and wherein at least one temperature probe is positioned at said local transversal constriction () of the conduit.

Roasting apparatus

The invention concerns an apparatus for roasting coffee beans comprising: —a vessel () to contain coffee beans, —a heating device () to heat coffee beans contained in the vessel, —a control system () operable to control the heating device and configured to apply a roasting recipe (R), wherein for a customised quantity m of coffee beans of type Ny introduced inside the vessel, —the control system is configured to obtain at least the quantity m of coffee beans introduced inside the vessel and the type Ny of coffee beans introduced inside the vessel, and —based on the obtained type Ny, the control system is configured to get access at least to a roasting recipe Ry, said recipe being adapted to the roasting of one pre-determined quantity M of beans of type Ni, and to said pre-determined quantity M, and —based on the accessible roasting recipe Ry and on said obtained quantity m of coffee beans introduced inside the vessel, the control system is configured to determine the roasting recipe (R) to be applied to the quantity m of coffee beans of type Ny introduced inside the vessel.

The invention concerns an apparatus for roasting coffee beans comprising: —a vessel () to contain coffee beans, —a heating device () to heat coffee beans contained in the vessel, —a control system () operable to control the heating device and configured to apply a roasting recipe (R) providing the temperature T, T, . . . to be applied at discrete successive times t, t, . . . , respectively, wherein for a customised quantity m of coffee beans introduced inside the vessel, —the control system is configured to obtain at least the quantity m of coffee beans introduced inside the vessel, and —the control system is configured to get access to at least one series of roasting recipes (R, R, . . . ) adapted to the roasting of different successive pre-determined quantities (M, M, . . . ) of beans of same type and to said pre-determined quantities Mi, Mi+1, . . . , and —based on said accessible series of roasting recipes (R, R, . . . ) adapted to the roasting of different successive pre-determined quantities (M, M, . . . ) of beans of same type and based on said obtained quantity m of coffee beans introduced inside the vessel, the control system is configured to determine the roasting recipe (R) to be applied on said obtained quantity m of coffee beans introduced inside the vessel.

The invention concerns an apparatus for roasting coffee beans comprising:—a vessel () to contain coffee beans,—an electrical heating device () to heat coffee beans contained in the vessel,—at least one temperature sensor () to measure temperature in the vessel, —a control system () operable to control the heating device, wherein the control system is configured to:—apply a roasting recipe dedicated to the roasting of partially pre-roasted beans comprising at least a temperature versus time profile by controlling the electrical heating device based on the measure of the temperature sensor,—detect a decrease of the consumption of electrical power of the heating device in function of time,—stop heating if no decrease of the consumption of electrical power happens after a set reference time ti.—continue or stop the electrical heating device depending on the type of identified beans.

Method for roasting coffee beans

The invention concerns an apparatus () for roasting coffee beans comprising:—a housing (),—a roasting chamber () presenting a bottom opening (),—an air driver () configured to drive air inside the roasting chamber through the bottom opening of said chamber,—an electrical heater () positioned below the bottom opening of the roasting chamber, said electrical heater being configured to heat air driven inside the roasting chamber,—the air driver and the electrical heater being positioned inside the housing () and the housing comprising a hot air outlet hole () designed to enable the passage of hot air from the housing inside the bottom opening () of the roasting chamber, and the electrical heater () being positioned just below the hot air outlet hole (),—the roasting chamber () being removably mounted to the housing (), the bottom opening () of the roasting chamber cooperating with the hot air outlet hole () of the housing when the roasting chamber is mounted to the housing, wherein the apparatus comprises a movable closure device () configured:—to cover the hot air outlet hole () while the roasting chamber is being removed from the housing, and - to uncover the hot air outlet hole () while the roasting chamber is being mounted to the housing.

The invention concerns a method for roasting coffee beans with a roasting apparatus () said roasting apparatus being positioned in a room and said roasting apparatus comprising: ⋅—a roasting device (), and ⋅—a smoke treating unit () configured to treat the smoke produced in the roasting device () and to prevent the dispense of air contaminants in the room.
