Energy consumed varies according to the stage it's at in the cycle . It draws for the vacuum pump, freeze coil and tray warmers, and if they are all going at once its a big load. Sometimes a full cycle start to end takes 15 or 20 hours if there is low moisture content in the food and stuff is already frozen. For example ice cream sandwiches. Or a cycle can take 50 hours, if its all liquid like raw scrambled eggs. It varies considerably based on whats being freeze dried. Pro tip : Don't freeze dry onions.
