Description

Automatic drier for food waste

An object of the present invention is to provide a food waste drying apparatus in order to solve the food waste treatment problem (separate collection of food waste, clean and clean environment of the kitchen, various pollution generated during processing) of our country.

The present invention relates to an apparatus for automatically drying food waste at home or in a restaurant. The problem of separation of food waste in our country has been frequently discussed, but it has not been possible to devise special measures or methods. In addition, many food wastes from homes contain not only other general waste but even toxic chemicals, which increases the difficulty of food processing. Burning these wastes generates a variety of toxic gases and also reduces the space for landfilling incinerated ashes. If the separate collection of food waste is more accurately followed, methods for recycling food waste without incineration have emerged, which can reduce water / air pollution and create a clean environment. In addition, the process of separating food waste so far involves picking up the food waste directly from the sink and handing it out to a garbage bag (or food waste container). Whenever you open or close these garbage bags or containers, you can't avoid the bad smell, and you are placed in the corner of the kitchen until all the garbage bags or containers are filled. The odor from the collected garbage and the infestation of various pests make it difficult to clean the kitchen. In addition, these collected wastes have a high water content and are not crushed, which leads to a slow fermentation rate, causing garbage and odor. Therefore, the current food processing system must be improved and various methods are being sought. Even the device that treats food waste by using fermentation agent, odor occurs during fermentation, and after fermentation, it has not been activated recently due to the problem of by-products processing and purchase of fermentation agent (for example, food waste extinction device using microorganisms) . Disposers that grind food waste to drains cause additional water pollution, and frequent breakdowns caused by hard materials such as bones and fruit seeds are not used in our country. Although many methods of drying and treating food waste have been proposed, they are not activated due to odor problems and economic problems (the drying equipment is expensive, the maintenance cost of the equipment-the electric charge and the repair cost are high) during drying (eg. Rinnai 'empty'). Therefore, the solution of the odor problem and economic feasibility must be considered for the recycling of food waste through the separate collection, the cleanliness of the kitchen, and the clean environment. The present invention that complements these problems is expected to play a very innovative role.

The object of the present invention is to maximize the drying efficiency of food waste by rotating the drum during drying in the automatic food waste drying apparatus, and to make it easier to remove the dried food waste more easily, ultimately in the drying process It is to provide a more hygienic and environmentally friendly kitchen environment by removing odors.

Figure 1 shows the assembled shape of the device. The device of the present invention is installed inside or outside the house, on the veranda, around the sink or inside the sink.

Figures 2 and 3 show a partial view of the interior of the present invention. The food waste inlet 102 is opened and the food waste with moisture (water) is put into the drum 107. After closing, the inlet 102 is closed. The injected food waste is automatically dried inside the drum cylinder 107 which rotates slowly at regular time intervals (rotating for 1 minute every 30 minutes). Odor generated during drying is discharged out by the exhaust fan 115 and the exhaust pipe 105. Exhaust pipe 105 is installed to be connected to the outer wall of the building so that the odor is completely discharged in the building as well as the kitchen.

Opening the inlet 102, the push button 119 is released to turn off the power indicator 118, the power is automatically cut off, except for the exhaust fan 115, all functions are stopped. When the inlet 102 is closed, the power indicator 118 is turned on while the pushbutton 119 is pressed, and power is supplied to the timer 114. The timer 114 is composed of two timers, timer-1 and timer-2, and are reset and operated by a supplied power source. The timer-1 is directly connected to the timer-2, the air circulation fan 116 and the heater 112, and is automatically turned off after a predetermined time (24 hours). Timer-2 drives low speed motor 113 intermittently (power off for 20 minutes and power on for 1 minute). The drum 107 is slowly rotated by the rotation of the low speed drive motor 113, and the food waste inside the drum 107 is inverted and mixed to help drying. The air circulation fan 116 and the heater 112 connected to the timer-1 are operated continuously for a predetermined time (24 hours) to dry the food waste. The exhaust fan 115 is directly connected to the input power source regardless of the timer 114 and always operates to prevent odors from leaking into the house.

4 and 9 show the exploded view of the apparatus, the inlet 102 for feeding food waste, the drum 107 for rotating and drying food waste, and the drum for structurally fixing the drum 107 to the frame 101. Holder 106, the drive motor 113 to rotate at low speed, the driven gear 120 is fixed to the circumferential surface of the drum 107 receives the rotational force of the low speed drive motor 113 to rotate the drum 107, A heater 112 fixed to the drum holder 106 to heat the air inside the apparatus to dry food waste, an exhaust fan 115 to discharge odor generated during the drying process, and an air circulation fan to circulate air in the apparatus. 116, the drum position adjusting knob 103 swinging the drum holder 106 so that the dried food waste is discharged inside the drum 107 so that the inlet of the drum 107 faces downward; Collecting bin 104, circuitry It consists of a timer 114 for controlling the same time.

Figures 5 and 6 show the position of the drum position adjusting knob 103 and the drum 107 when food waste is put in and drying. When the drum position adjusting knob 103 is pulled along the guide groove 111 in FIG. 5, the drum holder 106 is tilted while being rotated about the position 109 as shown in FIG. Higher than the floor. In this state, food waste is input and dried.

While the food waste is drying inside the drum 107, the food waste is additionally introduced into the drum 107 through the inlet 102. As the amount of food waste added increases, the food waste accumulates on the bottom surface of the drum 107. The food waste is completely dried within 24 hours after the rotation of the drum 107, the heater 112, the air circulation fan 116, and the exhaust fan 115. When food waste of about two weeks is accumulated inside the drum 107 based on a family of four, it occupies about half of the drum, and the dried food waste is discharged.

7 and 8 show the positions of the drum position adjusting knob 103 and the drum 107 when discharging the dried food waste. When the drum position adjusting knob 103 is pushed along the guide groove 111, the drum holder 106 rotates around the point 109 fixed to the frame 101 (the drum holder is fixed to the frame by a screw). The inlet of the drum 107 is lowered (see Fig. 8). At this time, when the inlet 102 is closed, the dried food waste inside the drum is automatically discharged to the collection box 104 by the rotation of the drum 107. Then, the dried waste of the bin 104 is discarded as general waste.

The drum holder 106 supports the drum 107 so as to be inclined to the frame 101 (see Figs. 6, 8 and 9) and serves as a rotation guide of the drum 107 (see Figs. 2, 3 and 9). . The bottom center 202 of the drum 107 is bolted (allowing rotation of the drum only) to the bottom center 201 of the drum fixing holder 106, and the circumferential surface 203 of the inlet of the fixing holder 106 Serves as a rotational guide of the outer peripheral surface 204 of the drum 107 inlet. Therefore, the drum 107 was to be smoothly rotated with a minimum rotational friction.

As described above, in the present invention, the food waste is automatically processed at the place where the food waste is generated by using the automatic food waste drying apparatus, and there is no need to move the food waste while blowing the odor, and incineration in a landfill or wet state There is no. Therefore, food waste is no longer expected to be an issue of social environmental pollution.
