Diseño y construcción de una máquina elaboradora de empanadas para la MICROEMPRESA SAL Y DULCE.

Abstract

The following research was focused on the problem existing at bakeries from Riobamba which are forced to change the presentation of patties during the quality control process, that is why it was necessary to choose the best alternative through the concurrent criteria; for this a QFD matrix was used in order to relate the sponsor and the engineer´s criteria. The result was an appropriate patty maker machine. The machine is in charge of dosing the filling of patties and obtaining a continuous quality sealing and an efficient Patty form emphasizing the production time. The machines I sable to produce 720 patties per hour; this increases the competitiveness of the product. The machine is mechanical and it is AISI 304 iron-made as required by the food industry; it also contains a 1740 rpm ¾ HP motor coupled to a speed reducer which performs 43.5 rpm and an intermittent phase controlling system based on a Geneva cross. Its work table is rounded to ease the labor for the worker, thus it accomplishes the sponsor´s expectations in a 95%. A cost-benefit analysis was carried out in order to study the economic feasibility to invest in the construction of this machine. The internal rate of return was 86,19 %, higher than the annual interest offered by the bank this demonstrates the feasibility of the project.
