Diseño y construcción de un equipo reductor de tamaño de Berro, Espinaca, Zanahoria

Abstract

The design and construction of a grinder hammer was performed in order to reduce the size of spinach, carrots and watercress to a desired diameter 0, 5 - 1 cm, which will serve in the professional, ed ucational and didactic field at the Industial Processes, Faculty of Science at ESPOCH . For the design of the machine, we proceeded to determine experimentally in the laboratory the optimum moisture with which the raw material must come out from the closet type dryer, this is 10%; therefore, the machine has an engine power of 2 hp essential for the proper ope ration thereof, a force of 2057, 4 N to break leaves of watercress and spin ach and chop carrots, torque 31, 8897 J that allows full rotation of the hammer s when chopping, hammer area which is 0, 0019355 m2 with watercress, spinach and carrots are chopp ed to a diameter of 0, 5 cm, a feed hopper with a volume of 0, 00125 m3 which supplies the raw material input, a d aily production of 240 kg/h ; these features all ow the total chopped material. As a result was obtained a mincer hammer with a yield of 89 , 7 % and an efficiency of 73, 96%, with positive results and high end indicating that you can process the raw material to the diameter of 0,5 - 1cm. We recommend using th e grinder hammer in the laboratory for future research within the education field as productive.
