Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO PARA DESHIDRATAR, ECONOMICO DE ENERGIA, ADAPTADO PARA LA COCHURA DEL YESO. TIENE UNA ENVOLTURA EXTERIOR (1), INTERIOR (6), CONOS DE EVACUACION (7) Y (10) ENSAMBLADOS SOBRE ESTAS ENVOLTURAS. UN QUEMADOR (11) Y UNA VALVULA DE CIERRE (5) COMPLETAN EL DISPOSITIVO. A FIN DE AUMENTAR LA PRESION EN EL HORNO, ESTA PREVISTA UNA TAPA (12), UNA VALVULA DE CIERRE DE YESO (13) Y UNA VALVULA DE VAPOR (14). EL TRATAMIENTO SE EFECTUA EN ESTADO SECO O HUMEDO, SIENDO ESTE ULTIMO INTERESANTE PARA EL TRATAMIENTO DE PRODUCTOS AISLANTES O PARA EL YESO MODIFICANDO LA NATURALEZA DEL YESO. EL CAMBIO TERMICO PERMITE TRATAR LOS PRODUCTOS A TEMPERATURA BAJA. LA CAMARA DE COMBUSTION CENTRAL EVITA LAS PERDIDAS POR RADIACION. EN UNA APLICACION A LA COCHURA DEL YESO, SE HAN OBSERVADO ECONOMIAS DE ENERGIA DEL 50 % RESPECTO A LOS APARATOS TRADICIONALES.
