The present invention relates to a food waste fermentation drying apparatus, wherein the food waste fermentation drying apparatus is a fermentation base body to clean up even the odor generated during fermentation and foreign matters contained in fermentation air and water while improving the fermentation efficiency of food waste ( 100), the dehumidifying purifier 200, the deodorizer 300, including a main configuration.

Fermentation base 100 according to the present invention is formed at both ends of the inlet 101 and the outlet 102, the inner space is divided by the diaphragm 114 is provided with a transfer hole 112, heating line 116 The fermentation tank 110 is heated by the fermenter 110, the stirring blade 120 rotates inside the fermentation tank 110, and installed in communication with each fermenter 110, a plurality of exhaust holes 132 are formed, the fan ( The exhaust pipe 130 for exhausting the internal air by the operation of the 134 is provided.

At this time, the fermentation base 100 is provided with an inlet 101 for injecting food waste on one side upper portion, the discharge port 102 for discharging the food waste of the fermentation form fermented in the other lower portion is formed, the inlet ( 101 and the outlet 102 is provided to be opened and closed by the door.

In addition, the fermentation tank 110 has a bottom surface is formed in a hemispherical shape in consideration of the turning radius of the stirring blade 120, the internal space is divided by the diaphragm 114, in Figure 1 fermentation tank by two diaphragms 114. The state in which 110 is divided into three places is shown.

At this time, each fermentation tank 110 divided by the diaphragm 114 is gradually formed in a narrower width from the inlet 101 side toward the outlet 102 side. This is large because the volume of water is contained in the food waste is initially introduced, but the volume of the fermentation tank 110 is reduced in step by taking into consideration that the volume is reduced by evaporation of moisture during fermentation, the whole of the fermentation base 100 There is an advantage that the treatment capacity to volume is increased.

In addition, since the food waste is fermented in each fermentation tank 110 divided according to the degree of fermentation, even if food waste is frequently introduced, the fermentation process is continuously performed, and in particular, each fermentation tank 110 temperature is independently maintained and new. While the phenomenon that the internal temperature of the fermentation tank 110 is prevented from dropping by the introduced food waste, the fermentation temperature is uniformly maintained at the set temperature has the advantage of improving the fermentation efficiency.

And, the food waste fermented in the divided fermentation tank 110 is conveyed step by step through the transfer hole 112, where the transfer hole 112 is gradually lowered from the inlet 101 side toward the outlet 102 side. Is placed.

The food waste put into the fermentation tank 110 adjacent to the inlet 101 is moved to the next fermentation tank 110 through the transfer hole 112 easily by the stirring blade 120 in a large particle state, the transfer hole 112 Is formed on the top of the diaphragm 114 to prevent the unfermented food waste to move to the next fermentation tank 110 indiscriminately.

Then, the food waste transported to the next fermentation tank 110 is broken down as the evaporation of water is formed in a small particle state so that the transfer hole 112 is gradually formed in a low position to facilitate the transfer through the stirring blade 120.

At this time, the odor generated during the food waste fermentation inside the fermentation tank 110, foreign substances contained in the fermentation air, moisture is installed to communicate on each fermentation tank 110, a plurality of exhaust holes 132 is formed, By the operation of the fan 134 is discharged to the outside by the exhaust pipe 130 for exhausting the internal air. Here, the exhaust hole 132 is determined in consideration of the area of each fermentation tank 110 and the amount of moisture generated in each fermentation tank 110.

As an example, the fermentation tank 110 adjacent to the inlet 101 of the fermentation base 100 has a large amount of moisture contained in the initial food waste, so that the most water is generated during fermentation, so that the exhaust hole 132 is disposed at the inlet 101. It is preferable to form a wider interval toward the outlet 102 side to be arranged so that the number of installation gradually decreases.

In FIG. 3, the stirring blade 120 is connected to the drive shaft 118 installed to penetrate each fermentation tank 110, and is installed in the longitudinal direction of the drive shaft 118 so as to pivot along the inner circumferential surface of the fermentation tank 110. And, the inlet 101 is provided with a slanted inclination angle toward the outlet 102 side.

Is exposed to the outside of the tank 210 is provided with a cooling pipe 230, the fan 232 is installed.

Here, the coolant 211 (for example, water) is filled with 40 to 60% of the inside area of the tank 210 so that the end of the inlet 220 is locked, and the coolant 211 that is insufficient during use is controlled by the water quantity control valve. It is automatically charged.

In addition, the injection port 220 is installed in the longitudinal direction such that the air generated in the fermentation tank 110 is vertically injected into the refrigerant 211, and the vertically injected fermentation air is injected into the refrigerant 211 as shown in FIG. The foreign matter is removed as well as the moisture is condensed out due to the temperature difference.

At this time, the cooling pipe 230 is installed to prevent the temperature rise of the inside of the tank 210 and the refrigerant 211 by the air inside the fermentation tank 110 injected through the inlet 220. Cooling pipe 230 is one end is connected to the fan 232 installed outside the tank 210 and the other end is arranged bent in a zigzag form while going in the upper direction from the inner bottom of the tank 210.

Accordingly, the heat exchanged with the refrigerant 211 is primarily performed while the external air is transferred through the cooling pipe 230, and the air heat-exchanged with the refrigerant 211 is transferred to the upper portion of the tank 210 to be moved by the refrigerant 211. The air remaining in the tank 210 in the state of being purified (moisture and foreign matters removed) is guided to the discharge port 216.

On the other hand, the end of the cooling pipe 230 is disposed to be spaced apart from the discharge port 216 so that the air remaining inside the tank 210 is more quickly transferred by the external air transferred through the cooling pipe 230, the outside It is preferable that the end is bent so that the air is sprayed horizontally.

In addition, the tank 210 has a bottom surface formed as an inclined surface, and as the sediment discharge port 214 is formed at a lower end of the inclined surface, foreign matter precipitated at the bottom during use is collected to the sediment discharge port 214 and discharged cleanly.

In addition, the deodorizer 300 according to the present invention is connected to the dehumidifying purifier 200, and removes the odor contained in the inhaled air in which the foreign matter and moisture is removed. Deodorizer 300 is formed by an anion group that decomposes malodorous molecules contained in the air by electrolysis. The deodorizer 300 sucks contaminated air that has passed through the dehumidifying purifier 200 into a fan and removes odors of 0.01 μm as well as various microorganisms including ultrafine dust bacteria and viruses by anions.

On the other hand, the deodorizer 300 using the electrolysis has a disadvantage in that the air containing a large amount of moisture is easily broken, but the moisture contained in the air by the dehumidifying purifier 200 is condensed and removed to improve the deodorization efficiency Of course, there is an advantage that the failure is prevented even for a long time use.
