To be more specific, the sawdust food waste mixture formed by adding and mixing sawdust to a food waste to be collected at a predetermined ratio is put into an agitating tank in which hot water is circulated from the outer surface, and air is sprayed from the bottom of the agitation tank The mixture of sawdust food waste is collected at the center by a central gathering device installed on the inner bottom surface of the stirring bar, and a mixture ascending moving device using compressed air or a screw is installed at the center of the stirring bar to rise along the rising induction pipe, The sawdust food waste mixture is collected at the center by the central gathering device while spraying the air as described above, and is lifted up by the ascending moving device to repeatedly perform the process of dropping the sawdust food waste mixture while agitating and drying the sawdust food waste mixture Food waste stirring device Intended.

As a conventional apparatus similar to the food waste stirring apparatus according to the present invention, there are a domestic utility model registration No. 20-379391 entitled " apparatus for disposing food waste, "and a utility model registration No. 20-407327. Open No. 10-2004-96854 "Method of stirring a food waste disposal" and disclosures thereof are disclosed in Korean Patent Application Laid-Open No. 10-2004-30734 entitled " Method of Manufacturing Food Waste Handler Having Screw Rotation Function " Patent Document No. 10-2006-42923 "Food Waste Treatment Device", and Patent Registration No. 10-605789 "Food Waste Treatment Device with Screw Rotation Function" are known.

The Utility Model Registration No. 20-379391 entitled " Food Waste Extinction Treatment System "is a device for disposing food garbage, wherein an excel hose is installed on the outer surface of a cylindrical stirring tank to supply hot water from a boiler, A plurality of agitating blades are directly installed on the rotating shaft so that a mixture of the food waste and the bio-chip (right coconut shell) can be agitated while the agitator is rotated by a motor, Or a support is provided on the outer side of the rotating shaft (rod), and a long curved biochip inducing vane is provided at the lower end of the rotating shaft (rod) to stir the loaded biochip.

However, there is a problem that the drying ability (productivity) is deteriorated because the food waste put into the stirring tank and the bio-chip (the right coconut palm shell) are simply stirred by hot water heat and the air can not easily penetrate into the interior of the mixture , The contact area of the elechel pipe is reduced due to the line contact with the stirring tank, and thus there is a problem that the heat transfer ability is deteriorated.

In the utility model registration No. 20-407327 entitled " Horizontal rotation interruption means of the agitation apparatus agitation apparatus ", a shaft rotated by a motor is provided at a central lower end of a stirring tank, and a plurality of stirring wings are supported by a support rod And a plurality of horizontal rotation interruption means are installed at a predetermined interval on the upper surface of the bottom of the stirring tank so that the stirring residue can not be rotated.

However, this is because it moves along the inner edge of the agitating tank of the stirring vane and hinders the movement simply by the horizontal rotation disturbing means, so that the agitator can not be efficiently agitated, and since the agitator is simply rotated and moved, there is a problem.

Open No. 10-2004-30734, entitled " Method of Manufacturing a Food Waste Handler Having a Screw Rotation Function ", is provided with an inflow base (hopper) at an inner lower end of a housing capable of opening and closing the lid from above, The agitating cylinder is vertically installed in the center, and a screw rotated by a motor is installed inside the agitating cylinder. Food waste is introduced into the housing through the inlet port, the screw is rotated by the motor, (Hopper) is moved to the upper side of the agitating cylinder, and falls down from the upper end of the agitating cylinder and drops into the inside of the inflow base (hopper).

However, there is a problem that the process of raising the food waste put into the inside of the housing by the operation of the screw up to the upper side of the stirring cylinder is repeated simply and repeatedly, and stirring is performed without applying heat, The food waste adhered to the inner surface of the hopper is adhered to the inflow base (hopper) without dropping, so that the food can not be stirred evenly, and the stirring (processing) ability is also deteriorated.

However, this is because the food waste put into the agitating cylinder is simply agitated by the stirring vanes installed up and down, so that the food waste can not be stirred efficiently, and the stirring (processing) ability is also remarkably deteriorated.

Japanese Patent Laid-Open Publication No. 10-2006-42923 entitled "Food Waste Treatment Apparatus" is a device in which a shaft is installed at the center of the inside of a cylindrical stirring tank to be rotated by a motor, and a plurality of stirring wings are supported on a shaft And air is supplied to the upper side of the stirring tank by the air supply and deodorizer, and the odor generated in the stirring tank is sucked to the outside and deodorized.

However, this is because the food waste put into the stirring tank is stirred by the rotating stirring blade, so that the food waste can not be efficiently stirred and the efficiency of stirring is lowered. In addition, since air is supplied from the upper side of the stirring tank, There is a problem that the fermentation processing ability is deteriorated because it can not easily permeate into the food waste located on the lower side.

However, since the auxiliary stirring blades are formed in a single curved shape, the food waste can be moved simply but can not be gathered to the center. Since the food waste can not be gathered at the center, it is accumulated on the edge, There is a problem that the stirring ability is remarkably deteriorated because it can not be moved.

Further, there is a problem that the food garbage adhered to the inner surface of the stirring tank can not be separated and maintained in the attached state, so that the food garbage can not be stirred well and there is a problem that the ability to perform the decomposition treatment (drying) .

Particularly, among the conventional devices, a device in which a large number of shafts connected to a lift plate are rotated (horizontally moved) while stirring the food waste is installed. However, And there is a problem that the food garbage stuck to the disturbing device is corrupted and the stench becomes extreme. There is a problem in that the shaft is connected to the rising plate so that the weight becomes heavy, so that the capacity of the motor becomes large, There is a problem.

In addition, the apparatus adopting the screw method has a problem that the content is not mixed with the liquid but is mixed with the sawdust and the food garbage, so that the contents are stuck to the screw blade, There is a problem that a separate auxiliary device must be installed in order to solve the problems of the present invention. Even if the lower end of the stirring bar is formed into a sloped hopper shape, stirring can not be easily performed because the contents can not flow smoothly there is a problem.
