In the food industry, the dosage of food additives in solution is done with dosing pumps or other instruments that involve expenses. In other industries (agriculture) the dosing process is carried out using Venturi type depressants which take advantage of their design to be able to dose additives (fertilizers) to the crops. That is why this research was conducted in order to design a Venturi type depressivo capable of dosing food additives. A food matrix was used (solutions of 11, 13 and 15 ° Brix) and citric acid was used as the additive to be dosed. This work was carried out by combining three methodologies: computational fluid dynamics (CFD), screening and design optimization. Fluid flow simulation was performed using computational fluid dynamics (CFD). The screening was done using the Taguchi method; which allowed to study six factors of interest: angle of convergence, angle of divergence, throat diameter, length of the throat, total length of the capillary and diameter of the capillary. The optimization of the design was carried out using the Response Surface Method, generating optimal measurements for the length of the throat, the height and the diameter of the capillary, which were 6,35; 101,6 and 6 mm, respectively; these measures generated 10,56; 10,54 and 10,56 percent suction performance for 11, 13 and 15 ° Brix solutions. The optimal model was manufactured (printing); the piece allowed the validation of the simulated device achieving a good relationship between the real performance and that obtained by simulation being 11,58; 11,56 and 11,64 percent the maximum suction yields generated for 11, 13 and 15 ° Brix, respectively. Finally, using the piece as a dosing instrument for an acidulated sample, the possibility to regulate the acidity of a sucrose solution using the Venturi device was verified.
