A protective device (1) comprising a protective module (2) is provided. The protective module (2) comprising:- at least one substantially L-shaped lamella (3);- at least one frame (4) transversely arranged to at least one lamella (3) and configured to be removably coupled to at least one lamella (3);- coupling means (5) comprising at least one slot (6) obtained on the lamella (3) and/or on the frame (4) and a coupling element (7, 8), the coupling element (7, 8) being configured to be removably introduced in the at least one slot (6) of the lamella (3) and/or frame (4).

Described is a method for adjusting the brightness of a plurality of light sources (SL) of the LED type arranged to form a first group (G1) having a first number (n1) of sources, the method comprising the following steps: - providing a control unit (3); - providing a plurality of current adjustment modules (2), each associated with a respective light source (SL) and connected to said control unit (3), to be controlled by it, and to one of said light sources (SL) to feed it with power supply current; the method also comprising the following steps, carried out by the control unit (3): - turning on the light sources of the first group (G1) to emit light at a first brightness (L0) and controlling the current adjustment modules (2) of the first group (G1) with a first current (I0); - decreasing the power supply current of at least a part of said current adjustment modules (2) of the sources of the first group (G1), down to a predetermined threshold current value (I*), which corresponds to a second brightness level (L1), lower than the first brightness (L0), and consequently carrying out the following steps: - turning off a second group (G2) of light sources (SL), having a second number (n2) of sources, with said second group (G2) of light sources (SL) defined by a part of the light sources (SL) of the first group (G1).

A method, implemented by at least a computer (7), is provided, for optimizing the operation of at least a machine (1A; 1B) for the production of liquid or semiliquid food products, wherein said machine (1A; 1B) is provided with: - a processing container (2), - a stirrer (3) arranged inside said container (2); - a plurality of sensors (S), - a plurality of actuators (11, 12, 13), - a control unit (5) comprising an artificial intelligence control module (6), connected to said sensors (S) and actuators and configured to define a pre-trained classifier (CL), the control module (6) being trained using a first dataset; the method comprising the following steps: - labelling information received from the control unit (5) by assigning predetermined labels to said information, said labels representing a balance of the ingredients of the mixture being processed in the container (2), - running a training procedure of the artificial intelligence control module (6) using a second dataset comprising the aforesaid information having predetermined labels, to derive an additional artificial intelligence control module defining a classifier replacing the pre-trained artificial intelligence control module (6); - transmitting instructions for replacing the control module (6) with the additional substitutive artificial intelligence control model to the control unit (5).
