El presente trabajo de investigación titulado “Influencia del Tipo de Perfil deTostado del Café en la Calidad en Taza para una Tostadora de 2 Kg”, pretende darle solución al problema del bajo consumo per cápita del café a nivel nacional. La tesis es cuantitativa experimental y con método de investigación científico, que tiene como objetivo determinar la influencia del tipo de perfil de tostado del café en la calidad en taza para una tostadora de 2 kg de capacidad. En cuanto a la técnica de investigación se escogió un lote de café que tendrá características similares como: tipo de café especial con porcentaje de humedad 10.8-13%. Los tipos de perfiles se obtuvieron con una tostadora de café tipo tambor rotatorio con instrumentos para controlar la temperatura en el proceso de tostado, nivel de tostado final mediano claro. El primer perfil de tostado se obtuvo para un t...

ABSTRACT — This project is aimed at the agricultural sector, especially small and medium - sized tuber traders. Worldwide Peru ranks as the fourteenth producer of the Andean tuber, where potato production is the highest contributor to the economy of the agricultural sector due to the intense activity of about 330 thousand hectares of cultivation, distributed in 19 regions having the Junín Region as one of the largest contributors in the production of this tuber. For the marketing of the potato the most important part is its classification. That's why it has to be catalogued according to its dimensional and quality characteristics to establish a certain price for the product. That's why we designed a machine that performs the function of sorting by size in a much shorter time to minimize the labor employed. The prototype was designed through the fulfillment of a list of requirements an...

The following research work developed a post-harvest ginger washing machine to conserve and improve the quality of ginger in the province of Satipo. The harvest needs to go through a washing process to remove impurities and other residues, so the main objective of this research project was to design a ginger washing machine with an improved pressurized water system, with a horizontal drum that has turning paddles and a sample drawer for quality control, reusing the water by filtering it through a sand trap. This work was carried out by developing an adaptation of the VDI 2221 and VDI 2225 standards, resulting in 4 phases to develop the project: the first, gathering information; the second, defining the solution concept, which seeks the solution to the problem; the third, the development and design; and finally, the design/modeling of the machine using software to validate its operation. ...

In the construction industry there are several problems that negatively impact the environment from the process of obtaining materials, the construction of buildings and their use. That is why the bibliographic review research analyzes the use and application of the hemp-based brick with the support of the Scopus database and the VOSviewer software as data analytics, the characteristics of the brick were taken into account as well As an air pollution purifier, humidity reduction and thermal insulation, graphs related to these characteristics were obtained, highlighting the words with the highest frequency in the research, countries that published and bibliometric maps worldwide. The results help us determine that there is an application of this brick in countries with the greatest needs and growth and also in potential countries, however we believe that in Peru there is no analysis or in...

This research presents the design of an automatic machine for post-harvest garlic processing, integrating 3 fundamental processes: garlic stalk cutting, garlic shelling and finally garlic peeling, in order to optimize production, improve quality and reduce costs. The development of the research is confined to farmers in the regions of Peru, contemplating the optimization and automation of 3 garlic processes, in order to allow a faster processing and relieve the farmer's workload. The initial part of the design is the cutting of garlic stalks, followed by the shelling of garlic cloves and then the peeling process, the processes have a system of vacuuming of waste and residues to obtain better product quality. The design is validated through previous research and with mechanical and electronic design software, concluding a significant improvement of 9.15% and 96% in the efficiency and qual...

This work aims to design a mechanical transfer system that allows us to integrate the need for power and speed ratio existing in the industry to obtain a safe mechanism ensuring the transmission system, which is optimal for maintenance. The methodology con sists of two - stage gearbox design features a gear mechanism with a gear ratio of 10 to 1 to decrease the output speed and increase the motor torque. The gearbox design parameters were calculated using the Excel program; for the simulations the So lidWorks program was used. To check the gear analysis, the calculation of the safety factor of the pinion, the gears and the material validation are evidenced.
