ABSTRACT:
An apparatus and method for drying small lots of product, for example ear corn. The method includes simultaneously directing air flow through the product while weighing the product from time to time to derive moisture content to the product. Air temperature and flow can be adjusted to desired levels for controlling the drying process. The apparatus includes an air permeable product bin and a docking station for receiving the bin. A scale is associated with the docking station to obtain weight measurements during the drying process. An air plenum supplies controlled air flow to the docking station. The structure allows monitoring of moisture content during drying and control of air flow. The temperature can also be controlled through control of an air gate from a main hot and cold air plenum.
