Diseño de un sistema para clasificar y contar truchas Arco Iris hasta 33 gramos de peso

Abstract

This technical project addresses the problems generated during the process of classification and quantification of rainbow trout, which in the country is done manually and by hand, increasing production time and costs. For the elaboration of this project, bibliographic information was compiled on the development stages of the species, as well as its morphology, allowing the development of a study to obtain relationships between weight - width and weight - length of the fish. During this study, a grading method was developed by means of troughs coupled to a chain transmission system and a water ramp for the humidification of the trout. Infrared sensors with PLC programming were used for quantification, to obtain a continuous process. The result was the design of a semi-automatic grading and quantification system made of AISI 304 L stainless steel in the components in contact with the fish, using polymers in the reduction trays and in the hydration system. The classification system uses chutes whose opening is controlled by regulating verniers obtaining exact values for the minimum and maximum size to be classified. The counting system uses infrared sensors that generate a light sweep that when interrupted by the trout generates a pulse that is processed in the PLC, thus obtaining a continuous process with a capacity of 10000 fish per hour.
