Description

Garbage disposing apparatus with Pressing and Heating}

When divided into a conventional crushing method of the food waste treatment machine, there is a cutting grinding method using a blade that rotates at a high speed, a helical twin gear compression grinding method of the juicer type, compression grinding method using a roller and a rotary blade and the like.

First, the cutting grinding method using a blade that rotates at high speed is inferior in grinding efficiency depending on the type of food waste. Crushing seeds, such as hard nuts and beans, requires additional fluids, such as water, which can cause fatal damage to the drive, especially when the vinyl of the film, such as the wrap type used in kitchens, is wound. In addition, high-speed rotation is required and causes a lot of noise and increase in manufacturing cost.

Second, the helical twin gear press grinding method in the form of juicer has the disadvantage of entering food waste under additional pressure, which leads to a complicated mechanical structure, and requires precision in mechanical processing. There is a discomfort that the residue remains artificially removed.

Third, the compression grinding method using a roller and a rotary blade, etc. should adjust the size of the roller and the rotary blade according to the size and strength of food waste, there are many problems to miniaturize.

In addition, if the conventional food waste disposal system is divided into large drying methods, hot air drying method using high temperature hot air, rotary dehydration method using centrifugal force, compression dehydration method using rollers, heat conduction drying method and micro-heating method using heat source such as electric heater Dielectric heating drying method using wave.

First, the hot air drying method takes a lot of time to dry by using high temperature hot air, there are many variations in drying efficiency according to the air flow between food waste, there is a limit to the drying of large and solid food waste such as bone, There is a disadvantage in generating odors in the city.

Second, the rotational dehydration method using centrifugal force has a mechanically simple structure, but it is very difficult to dry food wastes containing a lot of moisture in cells such as vegetables at less than 70% moisture content, and there is a lot of residual moisture in the processed food wastes. In case of long term storage, additional drying process is required.

Third, the compression dehydration method using a roller or the like has to increase the size of the roller according to the size of the food waste, there is a limit to dry less than 50% moisture content, there is a disadvantage that clogging the draining net and the like.

 Fourth, the heat conduction drying method using heat sources such as electric heaters has high efficiency at the initial stage with high moisture content, but the efficiency is drastically lowered due to poor thermal conductivity at the final stage with low moisture content, and the surface temperature of the dryer is increased to shorten the drying time. In some cases, food waste burns down.

Fifth, the genetic heating and drying method using microwave has high heat efficiency by directly heating food waste, but when the phenomenon of concentration of electromagnetic waves occurs, high temperature is generated in the local area, which may cause food waste or fire. When the interference occurs, the drying efficiency is drastically lowered, and when the food waste is low, there are many disadvantages in design such as increasing the reflected wave and shortening the life of the magnetron, and the manufacturing cost is high.

As such, the conventional food waste processor has a disadvantage in that the mechanical structure, such as applying the above-described grinding method and drying method and undergoing a transfer process in an intermediate stage, is complicated and has low efficiency.

The present invention relates to a food waste disposer, comprising a food waste disposer configured to evaporate moisture of food wastes by pressing-heating so as to simultaneously crush and dry the injected food wastes. Maximize the thermal efficiency of evaporating and drying the moisture contained in the food waste, minimize the food waste remaining in the food waste processor, prevent the food waste remaining in the food waste disposal from causing decay and odor, and processed food waste Is to facilitate storage and processing in powder form.

In order to solve the above disadvantages, the sun gear 200, the plurality of planetary gear 201 and the ring gear 202 between the drying chamber-top 100 and the drying chamber-bottom 101 inside the drying chamber-bottom 101 And a heater 300 which is a heat source is installed outside the drying chamber-bottom 101.

As the sun gear 200 connected to the reduction motor 400 rotates the planetary gear 201 by rotation, the food waste 500 is pressed onto the wall surface of the drying chamber-bottom 101 heated by the heater 300. The compressed food waste 500 is pulverized to eject all the moisture inside. The ejected water is evaporated by the wall of the heated drying chamber-bottom 101.

By using the planetary gear combinations 200, 201, and 202, pulverization and drying occur at the same time, thereby simplifying the mechanical device, thereby minimizing the cause of failure.

In addition, the food waste 500 may be compressed between the planetary gear 201 and the drying chamber-bottom 101 heated by the heater 300 to maximize the thermal efficiency by evaporating the extracted water.

It will be described below with reference to [FIG. 1], [FIG. 2], [FIG. 3] attached to the present invention "food waste disposal apparatus using the compression-heating".

In the food waste processor to dry the food waste by evaporating the moisture while crushing the food waste as shown in Figure 1, the food waste processor is open the lid 110, the food waste introduced into the drying chamber-upper 100 is crushed and dried To be made at the same time, the sun gear 200 is installed in the lower center of the drying chamber-lower 101 connected to the reduction motor 400 and rotated, and the plurality of planetary gears 201 to be rotated in conjunction with the sun gear 200. And a ring gear 202 disposed between the drying chamber upper part 100 and the drying chamber lower part 101 to guide rotation of the plurality of planetary gears 201, and a drying chamber as a heat source for evaporating moisture of food waste. Heater 300 installed on the outer side of the lower portion 101, the steam outlet 130 for discharging the water evaporated by the heat generated from the heater 200 and the residual moisture amount detected by the sensor to complete the drying process Food waste litter It consists of a discharge valve 121 that is opened and closed to automatically discharge through the outlet (120).

In the present invention configured as described above, the thermal efficiency of evaporating and drying the moisture contained in the food waste is maximized to quickly dry the moisture, and the food waste put into the drying chamber-upper 100 is not crushed and dried without going through the transportation process of the food waste. Since it is made and discharged at the same time, the amount of residues remaining in the food waste disposal system is minimized, and the residues are sufficiently sterilized to reduce rot or odor.

Here, looking at the operation of the present invention in detail as follows.

The user opens the lid 110 and injects food waste into the drying chamber-top 100.

Closing the lid 110 and pressing the operation button to rotate the sun gear 200 connected to the reduction motor 400 rotates a plurality of interlocking planetary gears 201, the planetary gear guided by the ring gear 202 ( 201) crush and stir the food waste while rotating and idle.

At this time, the food waste is discharged from the water contained while being compressed between the planetary gear 201 and the wall of the drying chamber-bottom 101, the discharged water is the inner wall surface of the drying chamber-bottom 101 heated by the heater 300 Will evaporate.

As this process is continuously repeated, the food waste put into the drying chamber-top 100 is compressed and heated to dry.

On the other hand, the moisture evaporated by the drying chamber-bottom 101 heated by the planetary gear 201 and the heater 300 is discharged to the steam outlet 130, at this time, the residual moisture is detected by the sensor in accordance with the dry state Continue drying or complete the drying process.

When the drying process is completed, the heater 300 is turned off, the discharge valve 121 is opened, and the planetary gear is continuously rotated to discharge the processed food waste.
