Smart food processing apparatus and method

1. A food processing apparatus for preparing a fluid food product comprising:

a food processing chamber including a blade arrangement driven by a motor;

a particle sensor arranged to measure an actual particle size within said fluid food product in said food processing chamber; and

a controller arranged to control said motor, wherein the controller is communicatively coupled to the particle sensor and is configured to disengage said motor in response to a signal from the particle sensor indicative of the actual particle size reaching a threshold value of no less than 400 μm within said fluid food product.

2. The food processing apparatus of claim 1 , wherein the threshold value is in a range of 400-850 μm.

3. The food processing apparatus of claim 2 , wherein the threshold value is in a range of 400-600 μm.

4. The food processing apparatus of claim 1 , wherein the controller is further responsive to a threshold value selection signal and is configured to select the threshold value based on said threshold value selection signal.

5. The food processing apparatus of claim 4 , further comprising a user interface communicatively coupled to the controller, wherein the user interface is configured to generate the threshold value selection signal in response to a user making a selection with the user interface.

6. The food processing apparatus of claim 5 , further comprising a communication interface communicatively coupled to the controller, wherein the communication interface is configured to receive the threshold value selection signal from a remote device.

7. The food processing apparatus of claim 1 , wherein the particle sensor is integrated in the food processing chamber.

8. The food processing apparatus of claim 1 , wherein the particle sensor is wirelessly connected to the controller.

9. The food processing apparatus of claim 1 , wherein the particle sensor is one of: an image sensor, a camera, an ultrasound sensor, and a Brix sensor.

10. The food processing apparatus of claim 9 , wherein the particle sensor is an image sensor.

11. The food processing apparatus of claim 10 , wherein the particle sensor comprises a detector and at least one light source arranged to project light onto the detector, said at least one light source being separated from the detector by an optical path inside the food processing chamber, said at least one light source being protected inside the food processing chamber by a mesh enveloping the at least one light source.

12. The food processing apparatus of claim 1 , wherein the food processing apparatus is a blender, juicer, or baby food maker.

13. A method of operating a food processing apparatus for preparing a fluid food product, the method comprising:

driving, by a motor, a blade arrangement in the food processing apparatus comprising a food processing chamber;

measuring, by a particle sensor, an actual particle size within the fluid food product in the food processing chamber;

engaging the motor, communicatively coupled with a controller, to start processing the fluid food product in the food processing chamber;

receiving a signal from said particle sensor, communicatively coupled with the controller, indicative of the actual particle size within the fluid food product in the food processing chamber during said processing; and

disengaging said motor, communicatively coupled with the controller, if the signal from the particle sensor is indicative of the actual particle size within said fluid food product reaching a threshold value of no less than 400 μm.

14. The method of claim 13 , wherein said threshold value is in a range of 400-850 μm, preferably in a range of 400-600 μm.

15. The method of claim 13 , further comprising:

receiving a threshold value selection signal with said controller; and

selecting the threshold value based on said received threshold value selection signal.
