Non-combustible oil filled as a heat carrier inside
Is an electric heater arranged at the bottom of the oil jacket 2 and operated according to a command from a control device (not shown).

Further, the water tank 4 is a substantially rectangular parallelepiped container, 40 is water stored in the water tank 4, 41 is a float for supplying water so that the water level in the water tank 4 reaches a certain height. Of the automatic water faucet, 42 is a weir for overflow provided above the side surface of the water tank 4, 43 is an overflow pipe, and 44 is provided above the body of the container 1 so as to guide the steam in the container 1 to the outside of the container 1. The exhaust pipe 45, an ejector 45 provided at the free end of the exhaust pipe 43, 46 sucks the water 40 from the water tank 4, and ejects the water 40 to the ejector 45.
Is a pump that feeds the mixture of water and steam from the ejector 45 into the water in the water tank 4, and 48 is a drain valve provided below the side surface of the water tank 4.

The geared motor 5 is fixed to the upper surface of the water tank 4, 50 is the output shaft of the geared motor 5 whose free end vertically penetrates the center of the bottom of the container 1, 51 is its bearing, and 52 is the output shaft 50. Of the cylindrical bosses 520 and 521 attached to the projecting portion of the container 1 of the boss 5.
It is a rotary blade horizontally attached to No. 2.

Each of the rotary blades 520 and 521 is curved in a substantially C-shape, its edge is close to the inner wall surface of the container 1 on the way, and its free end side is turned up upward on the way and its outer side. A corrugated blade is provided from the fixed end of the edge to the position where the curling up starts. Thus, the rotary blades 520 and 521 are rotationally symmetrical and stepped, and the rotary blade 520 below the rotary blades 520 and 521 is attached to the boss 52 so as to be close to the bottom end plate of the container 1.

The casing 5 is a substantially rectangular parallelepiped box, and the container 1 is supported by a method (not shown) so that the upper edge of the container 1 is in close contact with the ceiling of the casing 5. An opening is provided in a portion corresponding to the input port 10 and the opening / closing door 13.

The operation of this device will be described below.
When using this device, first, water 40 is supplied into the water tank 4 from the automatic water faucet 41 that stops the water supply when the desired water level is reached, and then organic substances such as garbage are discarded in the container 1.

It is fermented and decomposed by aerobic bacteria, and then dried while being thermally decomposed.

At this time, it is desirable that the rotational speed of the rotary cutters 520 and 521 be set to 20 to 50 times per minute. If the rotational speed is less than 20 times per minute, the agitation of the organic matter becomes insufficient. Further, when the rotation speed exceeds 50 times per minute, the organic matter is crushed, and the organic matter containing a large amount of water becomes a paste or dumpling, so that the organic matter cannot be effectively decomposed and dried.

Further, since the heated oil 20 convects in the oil jacket 2, its temperature rises uniformly throughout, and the temperature is shown after the oil 20 reaches a certain temperature. Not held at a predetermined temperature by a control device. The gas in the oil jacket 2 is preferably replaced with nitrogen gas in order to prevent deterioration of the oil 20.

Further, the steam generated in the container 1 is sucked out of the container 1 through the exhaust pipe 44 by sending the water 40 in the water tank 4 to the ejector 45 by the pump 46, and the mixture of water 40 and steam is generated. Introduced into the water in the water tank 1,
Deodorized gas and excess water are overflow weir 4
2 over the upper edge and flows out from the overflow pipe 42.
The water level in the water tank 4 is constantly rising due to the water vapor generated from the material to be dried, and since tap water or the like is replenished as necessary, the water in the tank is constantly updated over the weir 42. And kept clean. In addition, this ejector 4
Water may be supplied to the tap water directly or after being pressurized by a pump. Thus, in this case, the ejector 4
By supplying water to the water 5, the water in the water tank 4 is constantly replaced and renewed.

Thus, in the device of the present invention, since the organic substances are decomposed and dried efficiently, after the completion of drying, the opening / closing door 13
Open and open the material to be dried in the container 1 to the outside,
After that, another organic substance may be newly charged from the charging port 10. As a result of repeating this series of steps, the water tank 4
When sludge accumulates on the bottom of the tank, open the drain valve 43,
After removing the water 40 in the water tank 4 and removing the accumulated sludge, water may be supplied to the water tank 4 again to decompose and dry the organic matter. In these steps, since the pressure inside the container 1 is reduced, the safety valve that takes in the outside air and adjusts the air pressure inside the container 1 and the atmospheric pressure inside and outside the container 1 when the lid 12 and the opening / closing door 13 are opened. It is recommended to provide a vacuum break valve for balancing.

The present invention is not limited to the above embodiment. For example, the number of blades of the rotary cutter is not limited to two, and may be one or three or more. In this case, the rotation speed of the blades is appropriately set according to the number of blades. Further, a gas burner or the like may be used as a heat source for heating the oil jacket, and further, the shapes of the container, the oil jacket, the lid, the opening / closing door, the rotary cutter, the water tank, the casing and other parts may be the same as those of the present invention. The design can be freely changed within the intended range, and the present invention is
The above description covers all modified embodiments that can be easily conceived by those skilled in the art.
