Abstract
Three ventilation systems were compared in loose and pallet box storages of potato. Low ventilation dose in the pile storage (25 m3/t·h) and high ventilation dose in the pallet box (120 m3/t·h) and pile storages were tested. The pallet box storage had a flow-around ventilation system. The following technical parameters were compared: average time of ventilation per day, capacity of ventilation, amount of air flowed through potatoes during the season and energy expenditures. Natural losses of the variety Triada in 3 potato storages were assessed. The highest natural losses were recorded in the pallet box storage (10.1%). In the pile storage, higher natural losses (7.7%) has been were stated at the low ventilation dose.
