Abstract

The present invention relates to an in vitro system for automatic chewing of solid and semi-solid food intended to simulate the human chewing process of a food sample, comprising a lower toothed ring and an upper toothed ring; and further comprising a force lever consisting of an arm from which a lead weight hangs, which is moved along the arm via the traction exerted by an electric motor controlled by a microcontroller board, which is connected by a spindle to the upper toothed ring; and wherein the shearing action is provided by an electric motor controlled by a microprocessor board which is connected to the shaft of the upper toothed ring via a chain. A second objective of the invention comprises a method for automatic chewing with controlled force and a specific number of chewing cycles and shear angle.

Dependent claims

An in vitro automatic chewing system for solid and semi-solid food (100), CHARACTERIZED in that it comprises:

a lower toothed ring (2) and an upper toothed ring (1) in charge of crushing and generating a shear on a solid or semi-solid food, wherein the lower ring (2) is connected through a connecting rod system to an electric motor (24) that executes in number of chewing cycles controlled by a microcontroller card;
the upper toothed ring (1) is in charge of exerting force and shear on the solid or semi-solid food;
a force lever (16) is connected by a spindle to the upper toothed ring (1);
the force lever is formed by an arm (16) from which a lead weight (14) hangs, which moves along the arm by means of the traction exerted by an electric motor (15) controlled by a microcontroller card;
and wherein, the shearing action is provided by an electric motor (17) controlled by a microprocessor card which is connected to the shaft of the upper toothed ring (1) by means of a chain.
