Abstract: The present invention comprises a tray with grooves and slots for recirculation of moist air for a humidor in operation, intended to conserve products, typically cigars, fresh and in their natural state. These grooves or channels are substantially parallel to each other, and each rounded groove preferably contains a lengthwise slot through the tray from the top to the bottom surface and located substantially in the bottom center of the rounded groove. These slots provide for the recirculation of moist air around and through each individual product. The humidor of the present invention consists of a plurality of such product-containing trays stacked and spaced vertically in a suitable case, including means for removal of the trays for insertion or removal of product. Space for moist air circulation is also provided around each sliding tray. The humidor of the present invention also contains a source of moisture and humidity sensing means.
