Title:
DRYING DEVICE AND DRYING METHOD
Document Type and Number:
WIPO Patent Application WO/2012/011600
Kind Code:
A1
Abstract:
Disclosed is a device for efficiently drying a material to be dried by increasing frequency and surface area of contact between said material and air, and a method thereof; also disclosed is a method of manufacturing low-cost dry fermented feed, dry fermented manure, etc., by using fermentation heat. Said material to be dried is suspended while displacing and agitating the material to be dried inside of a drying tank, and air is supplied from below; said material to be dried is repeatedly carried by air currents from the bottom to the top of said drying tank. By this means, the frequency and surface area with which the material to be dried uniformly contacts dried air are increased and the time until said material is dried is dramatically shortened. In a circulation duct, air jet nozzles are provided on the inner wall of a curved portion and the inner wall of a bottom portion of a circulation discharge port so as to generate an induction air current outside of the air current that blows said material to be dried upwards together with the air. By this means, damage to said material to be dried is prevented inside of said duct, smooth circulation is achieved, and uniform and quality manufactured products in a dried state are achieved. In material to be dried undergoing a fermentation process, fermentation and drying are facilitated in a storage place and during conveyance by air current by increasing the frequency and surface area of uniform contact with air, dramatically shortening the time until said material is dry, resulting in uniform and quality manufactured products of fermented feed / dry fermented manure of animal and plant residue having the added value from fermentation without the use of a new thermal power.
