Diseño y Construcción de un equipo de molienda y tamizado para hojas de aguacate, orégano y fibra de coco

Abstract

A sifting and grinding system has been built and designed in order to reduce oregano, avocado, and coconut fiber leave size to obtain medicinal herbs. The research stage started with the study of raw material together with simulation tests experimental ana lysis which determined the appropriate feeding humidity which value is 7%for oregano and avocado and 5% for coconut fiber. In addition the shock mechanical power for the particle fracture was also tested. Then it was designed by means of engineering calcul ations to obtain the necessary parameters for the wright performance. That  s why it was presented a solid stainless steel equipment for food containing supplying system, a transmission system, a grinding chamber, containing two static and rotary rotors coupled to the grinding elements, and an interchangeable sieve, a discharging system and an induction motor. Its capacity is 25 Kg/h, its operational speed is 3440 rpm, its power is 2 Hp, and a 220 V input. It has food applications with restrictions for fa tty materials which overpasses a 12% of humidity. A performance result of 96, 95% was obtained as a validation result as well as an equipment efficiency of 77%. An average of the used samples shows that the product meets the grain size requirements for med icinal herbs, which resulted from grinded vegetal material showing excellent organoleptic characteristic for its consumption. Thus it is necessary to make a deep analysis of its medicinal properties since its components are rich in active principles.
