Apparatus for roasting coffee beans according to the preceding claim, wherein C is equal to 1. 4. The coffee bean roaster according to claim 2 or 3, wherein, based on the determined Ni type, the control system is configured to: accessing a Cy coefficient specific to said coffee bean type Ny, and determining the roasting recipe (R) applied to the coffee beans by determining the temperature T _m applied to the number m of beans obtained at each of said separate consecutive times t ₁ , t ₂ , … as follows: if m>M, then T _mвti = T _Mвti + [T _Mвti ⋅ Cy ⋅ (m - M) / M] if m<M, then T _mвti = T _Mвti - [T _Mвti ⋅ Cy ⋅ (M - m) / M]. 5. Apparatus according to any one of the preceding claims, wherein the quantities (m, M) are quantities given by weight. 6. Apparatus according to any one of the preceding claims, wherein: the control system is configured to select an additional roasted bean application from a list of predefined applications (uα, uβ, etc.), and based on the specific Ny type and specific specific additional application ux, the control system is configured to access at least a roast recipe Ryx, said recipe being adapted to roast one predetermined number M of Ny type beans and the specific additional application ux of said roasted beans, and to the specified predetermined amount M, and moreover, based on the available roast recipe Ryx and the available predetermined amount M, as well as on the basis of said specific amount m of coffee beans loaded inside the vessel, the control system is configured to determine the roast recipe (R) used for said specific amount m of coffee beans, loaded inside the vessel, for a specific additional use of the roasted beans. 7. An apparatus according to any one of the preceding claims, comprising a measuring device (2) configured to measure the number m of coffee beans loaded into the vessel, said number m of coffee beans being automatically measured by the measuring device at the stage of determining the number m of beans loaded into the vessel. 8. Apparatus according to the preceding claim, wherein the measuring device is: scales for measuring the weight of coffee beans, or a device containing at least one cavity of a predetermined volume, or level sensor that measures the volume of coffee beans inside the vessel. 9. System for roasting coffee beans, comprising: apparatus (1) for frying according to any one of paragraphs. 1-8, and a device (2) for measuring the amount of coffee beans loaded inside the vessel, and wherein the control system (180) of the roaster is configured to determine the number m of coffee beans loaded inside the vessel and measured by the measuring device. 10. The method of roasting coffee beans using the apparatus according to any one of paragraphs. 1-8 and using a frying recipe (R) providing temperatures T _{in t1} , T _{in t2} , ... applied at separate successive times t ₁ , t ₂ , ... , respectively, including: determining the number m of coffee beans loaded into the vessel and the type Ny of coffee beans loaded into the vessel, and accessing at least a roasting recipe Ry on the basis of a certain Ni type, said recipe being adapted to roast one predetermined amount M of Ny type beans, and to said predetermined amount M, and based on the available roast recipe Ry and the available predetermined amount M and based on said determined amount m of coffee beans loaded into the vessel, determining the roast recipe (R) applied to the amount m of Ny type coffee beans loaded into the vessel. 11. The method according to the preceding claim, wherein the roast recipe (R) applied to the coffee beans is determined based on said available frying recipe Ry, said frying recipe Ry providing the temperatures T _Mvt1 , T _Mvt2 , ... applied at separate successive times t ₁ , t ₂ , ... , respectively, and based on said available predetermined amount M, and based on a certain number m of grains loaded inside the vessel, by determining the temperature T _m applied to the obtained number m of grains at each of these separate consecutive times t ₁ , t ₂ , ... as follows: if m>M, then T _mвti = T _Mвti + [T _Mвti ⋅ C ⋅ (m - M) / M] if m<M, then T _mвti = T _Mвti - [T _Mвti ⋅ C ⋅ (M - m) / M], where C≤1. 12.
