Abstract
A moisture reduction system for an automatic vending machine of the hot beverage type which utilizes a movable brewing chamber that opens for the addition of product, such as coffee. The system has a suction tube disposed adjacent the product supply tube and brewing chamber in its product fill position, which draws off moisture from the open chamber so that it does not accumulate on the product supply tube. A filter is disposed at the end of the suction tube to prevent product dust, such as coffee grounds, from being sucked into the tube.
