“Diseño y construcción de una máquina extractora de aceite de aguacate para el Laboratorio Farmaceutico Ecufarma con una capacidad de aproximadamente 4 - 7 kg/h, ubicada en Quito provincia de Pichincha”

Abstract

This project includes the design and construction of an avocado oil extraction machine with a capacity of 4 - 7 Kg / h for the ECUFARMA Pharmaceutical Laboratory. Chapter 1 begins with the study of the matter to be processed and to know the properties of the oil to be extracted. Once the material and its methods for oil extraction are known, the research of the components and the most profitable method for its extraction are used. As the last part of this chapter, we will proceed to write the theoretical foundation and the description of the design used for this purpose as the conical extruder screw, which is a mechanical device driven by an electric motor which ensures that the screw rotates clockwise the same as It is responsible for carrying the dehydrated avocado pulp in a linear manner and with a progressive increase in the diameter of the core of the screw to force its compaction with the walls of the jacket, which helps a continuous and high performance extraction of oil. In chapter 2 the selection of design alternatives is made and the study of similar machines used in food extrusion was used in order to find a model that meets the aforementioned requirements. In chapter 3 the static and dynamic design will be developed, based on stresses and deformations, the material and dimensions of each of the elements that make up the avocado oil extractor machine will be determined. Also, to obtain the design parameters, knowledge of the functionality of machines similar to the working conditions and the type of raw material was required. Once all the information had been collected, the elements were designed, complying with the concepts and recommendations of the designated tutor. After the design, the construction, assembly and start-up of the oil extractor machine was completed. In chapter 4 an economic study will be carried out, for which the costs and expenses involved in the construction of the machine will be calculated. Finally, this project is concluded with favorable results and some recommendations are made for the user in order to extend the useful life of the machine.
