A freeze-dryer like this has three parts. The first is the pump which doesn’t need any explanation. Next to the pump, there must be a water trap. This chilly compartment recondenses the water vapor, so it doesn’t get inside the pump or saturate the things you’re trying to dry. Lastly, there is the drying chamber where your items are placed to have their moisture taken out.
