Description

Household Food Waste Dryer {A DRYING MACHINE FOR FOOD WASTES}

The present invention relates to a household food waste drying processor, and more particularly, to a household food waste drying processor that can easily and quickly dry food waste such as fruit peels, vegetable residues, and residues generated in a general household. .

In general, food waste produced at home is a serious source of sewage and odor, which can be recycled as organic fertilizer or animal feed. Therefore, food waste discharged from homes and restaurants is separated from other recyclable wastes, and wastewater is discharged during the transport of such food waste to the treatment plant, and odor is emitted. Let's go.

<Description of the operation and effect of the drying processor according to the present invention>

Next will be described with reference to Figure 3 the operation and the resulting effects of the household food waste drying processor according to the present invention configured as described above.

First, the food waste (W) to be dried in the inner cylinder 30 is put in the drying chamber 20 of the main body 10. When the inner cylinder 30 is pushed in, the locking edge 31 of the inner cylinder 30 slides in the drawer type along the guide jaw 23 of the wall of the drying chamber 20. After the inner cylinder 30 is completely pushed into the drying chamber 20 and the door 40 is closed, the drying chamber 20 is lowered by the guide jaw 23 of the inner wall and the locking edge 31 of the inner cylinder 30. It is divided into space and upper space.

When the power switch of the control panel 11 is turned on, the heater 52 is driven together with the fan 53 of the heating unit 50. Accordingly, the outside air is forcibly sucked into the heating chamber 12 through the intake holes 13a and 13b of the main body 10 and is supplied into the heater case 51 (see arrow direction in FIG. 3). The air supplied to the heater case 51 is forcibly blown into the lower space of the drying chamber 20 through the holes 22 of the bottom plate 21 while being heated by the heater 52. The hot air supplied to the drying chamber 20 heats the inner cylinder 30 in which the food waste W is contained. Accordingly, the food waste (W) contained in the inner barrel 30 is also heated so that the moisture contained therein is evaporated to dryness with water vapor. What is generated in the food waste (W) during this drying process is accompanied by odor particles as well as water vapor.

Subsequently, the heat exchanged air while heating the inner cylinder 30 is discharged through the sub-exhaust port 24 by the fan 53 blowing force of the heating unit 50, and again through the induction duct 80, the drying chamber 20. Guided to the upper space. The air discharged to the upper part of the drying chamber 20 is forcibly sent to the deodorizing chamber 60 through the exhaust port 26 together with the water vapor generated from the food waste W.

In addition, as the sterilization lamp 90 installed at the upper end of the induction duct 80 is driven, the germs of the food waste are sterilized by the sterilization wavelength (ultraviolet rays) radiated therefrom. That is, the germicidal lamp emits ultraviolet rays having a wavelength of approximately 180 to 450 nm. Due to the ultraviolet rays, electrons and electron holes are formed in the upper space of the drying chamber 20 to form hydroxy radical (-OH) and super oxide having strong oxidation power. These hydroxy radicals and super oxides oxidize and decompose organic compounds into water and carbon dioxide. Therefore, when the sterilization lamp 90 is operated, the contaminants of the food waste are changed into harmless water and carbon dioxide gas. In addition, since bacteria and odor molecules in the air are organic compounds, when the sterilization lamp 90 is irradiated and oxidized / decomposed, steam sterilized in the drying chamber 20 is discharged through the exhaust port 26.

On the other hand, the water vapor and malodorous particles exiting through the exhaust port 26 enters the inside of the deodorizing cartridge 71 of the deodorizing unit 70, and the malodorous particles are absorbed and deodorized by the deodorant 71c filled in the deodorizing tube 71a. The deodorized water vapor enters the sump 73 through the steam guide portion 73a and the steam inlet hole 73b while leaving the deodorized cartridge 71. Water vapor from the sump 73 contacts with the inner surface of the cover 74 in contact with the atmosphere, condensed by condensation to form water droplets, which are dropped by their own weight and fall into the bottom of the sump 73 and into the sump. do. And the air in the sump 73 escapes to the atmosphere through the exhaust hole 73c. Therefore, the air is discharged in a state in which the odor is removed, as well as the state does not contain moisture, does not cause odor and discomfort during the food waste (W) drying process.

After the heating and drying process of the food waste W is completed, the door 40 is opened to take out the inner container 30, and the food waste W completely dried from the inner container 30 can be taken out and processed.

On the other hand, in the case where a considerable amount of water is collected in the sump 73 by using the food waste drying processor for a long time, the cover 74 is opened and then the steam guide 73a or the edge thereof is caught and lifted up from the main body 10. The sump 73 can be easily disassembled. And after discarding the water collected in the sump (73) again assembled in the reverse order of decomposition can be reused immediately. In addition, since the water in the sump 73 has undergone sterilization and deodorization through the sterilization lamp 90 and the deodorization cartridge 71, secondary pollution is not generated.
