Abstract

Insulated bins containing approximately 1800 kg (2 ton) were ventilated at airflow rates of 0, 2.3, 4.7, 9.4, 18.7, 37.5, and 74.9 m3/h/T(0, 1.25, 2.5, 10, 20, and 40 cfm/t). Replicated trials over a three year period showed that ventilating with an airflow rate of 18.7 m3/h/T (10 cfm/t) resulted in the lowest combined storage loss due to weight, sprouts, and rot. The time required to grade the tubers from the bins ventilated with airflow rates greater than 9.4 m3/h/T (5 cfm/t) was significantly less than that from those receiving lower airflow rates. There was no significant difference in tuber temperature at the top of the bins having an airflow rate of 9.4 m3/h/T (5 cfm/t) or more.

Resumen

Se ventilaron almacenes aislados, de una capacidad de aproximadamente 1,800 kgs. (2 tons.), con corrientes de aire a ritmos de 0, 2.3, 4.7, 9.4, 18.7, 37.5 y 74.9 m3/h/T (0, 1.25, 2.5, 10, 20 y 40 cfm/t). Pruebas replicadas realizadas durante un período de tres años mostraron que el hecho de ventilar con corriente de aire a un ritmo de 18.7 m3/h/T (10 p c /tm) dio como resultado la pérdida combinada por almacenamiento más baja en cuanto a peso, brotamiento y pudrición. El tiempo requerido para clasificar los tubérculos de los depósitos ventilados con corriente de aire a ritmos mayores de 9.4 m3/h/T (5 pmc/t) fue significativamente menor que en los casos de los que recibieron corrientes de aire a ritmos más bajos. No se registró diferencia significativa en la temperatura de tubérculo en la parte alta de los depósitos con ritmos de corriente de aire de 9: 4m3/h/T (5 pcm/t) o más.
