Rapid dehydrating/drying device usable in low temperature

Abstract

An article to be dried is transferred and pressed and held between a wire endless conveyor and a flexible conveyor. The wire endless conveyor is placed between a nozzle, including a sucking-out nozzle and a blowing nozzle, and the cushion conveyor to press, hold and transfer the article to be dried. The nozzle dehydrates/dries the article to be dried. When an article to be dried is narrower than the width of the nozzle, the area where the article to be dried does not cover the sucking-out nozzle or the blowing nozzle is automatically shut by the flexible conveyor. The article to be dried is dehydrated/dried while it is pressed, held and transferred so that a high speed air jet stream and high speed negative pressure air stream do not flow out/in to outer air. While the article to be dried is transferred, pressed and held by the flexible conveyor, water adhering to it is formed into minute water drops by the high speed air jet stream and the high speed negative pressure air stream. The minute water drops are sucked and removed on the high speed negative pressure air stream. Thus dehydrating/drying can be performed continuously without water evaporation heat, in a short time and efficiently with little energy. Further, articles of various sizes and irregular shapes can be dried.
