Abstract

UNA PLANTA DE TRATAMIENTO DEL AIRE QUE CONSTA DE UN BASTIDOR; UNA CINTA TRANSPORTADORA (4) ADAPTADO PARA ALIMENTAR ALIMENTOS A PROCESAR A TRAVES DE UNA ABERTURA DE TOMA (2) EN EL BASTIDOR, A UNA ZONA DE TRATAMIENTO DE AIRE, Y ALIMENTAR LOS ALIMENTOS PROCESADOS DE ESTA ZONA A UNA ABERTURA DE SALIDA (3) DEL BASTIDOR; UN INTERCAMBIADOR DE CALOR; Y UN VENTILADOR DE CIRCULACION PARA GENERAR UN FLUJO DE AIRE CIRCULANTE A TRAVES DEL INTERCAMBIADOR DE CALOR, LA ZONA DE TRATAMIENTO DE AIRE, Y EL VENTILADOR DE CIRCULACION SUCESIVAMENTE. SE CONECTA UN VENTILADOR REGULADOR DE PRESION (25) A UNA CAMARA (33) ADYACENTE A UNA DE LAS ABERTURAS DE TOMA Y SALIDA (2, 3) PARA GENERAR UNA DIFERENCIA DE PRESION POR LA ABERTURA SUBSTANCIALMENTE IGUAL A LA DE LA OTRA ABERTURA, MINIMIZANDO ASI EL INTERCAMBIO DE AIRE ENTRE EL INTERIOR Y EXTERIOR DEL BASTIDOR (1). LA CINTA TRANSPORTADORA (4) HACIA DENTRO DE ESTA ABERTURA PASA UN TUNEL CON AL MENOS DOS CONDUCTOS CORTINA DE AIRE QUE SON DIRIGIDOS SUBSTANCIALMENTE DE MANERA TRANSVERSAL AL PASO DE LA CINTA TRANSPORTADORA Y POR EL CUAL FLUYE PARTE DEL AIRE CIRCULANTE.
