Description

Food Waste Disposer Comprising A Low Temperature Catalyst Filter

The present invention relates to a food processor for using a microwave to evaporate the moisture of food waste in the food container. More specifically, the present invention relates to a food processor characterized in that a magnetron capable of providing a microwave can heat both an inner container containing food waste and a low temperature catalytic filter deodorizing function.

Food waste is discharged every day from homes and restaurants, but most of the waste is filtered and then disposed of. Since this increases the amount of garbage and causes odors to pollute the surrounding air, efforts have recently been made to reduce food waste at homes and restaurants. As one of these efforts, a food processor is widely used.

Moisture takes up a large portion of the food waste volume. It is efficient to reduce the volume of food waste in order to reduce the amount of food waste, so most food handlers adopt devices to remove moisture from food waste.

One method of removing moisture from food waste is to place a reactor that can dry food in a food processor, to allow food waste to be first introduced into the reactor, and the reactor is heated by a heater to separate water separately. The dried food waste, from which moisture is removed, is stirred and / or pulverized and discharged to the outside as a powder.

1 is a schematic cross-sectional view of a food processor according to the related art, which includes a drying furnace 10, a grinding motor 20, a grinder 21, a discharge bin 30, a pipe 40, and a drying furnace 10. ) Is provided with an inlet 11, an inlet opening and closing device 12, a gas outlet 15, an outlet 13, and an outlet opening and closing device 14.

Food processor according to the prior art, the crushing motor 20 in the lower part of the drying furnace so that the food waste introduced into the drying furnace 10 through the inlet 11 to be crushed, stirred and dried in the drying furnace 10 inside And a heater (not shown) for evaporating the moisture of the food waste pulverized in the crusher 21 and a gas outlet for discharging the evaporated water by the heater. 15 and the discharge opening and closing device 14 to be opened and closed to automatically discharge the pulverized / dried food waste through the outlet 13 after completing the drying process.

However, in this case, the food waste crushed by the grinder 21 is scattered in the drying furnace 10 and attached to the inner wall surface of the drying furnace 10. Therefore, the energy efficiency of evaporating moisture is lowered compared to the amount of heat input, the drying time is long, and there is a problem in that residual residue remains on the inner wall surface of the drying furnace 10 and causes odor.

In addition, when using a magnetron that provides a microwave as a heater, there is a problem that microwaves to be reflected from the inner wall surface of the drying furnace are not efficiently reflected by the food waste attached to the inner wall surface of the drying furnace.

On the other hand, the food heated in this way produces a gas with odor. Such gas is generally filtered by a deodorizing filter, and is generally discharged to the outside as a gas without odor. One of the filters used is a low temperature catalyst filter.

However, since the low temperature catalyst filter operates at a high temperature, heating is performed by placing a hot wire or a separate bending heater in the vicinity of the low temperature catalyst filter. In order to heat the low temperature catalyst filter separately, there is a problem in that high power is consumed.

The present invention is to reduce the energy efficiency by the food is scattered on the inner wall of the drying furnace to reduce the reflection efficiency of the microwave, and to solve the problem of generation of odor due to scattered food.

In addition, the present invention is to solve the problem of lowering the energy efficiency by heating the low-temperature catalyst filter through a separate heater.

In order to solve the above problems, the present invention, a grinder for crushing the input food; A magnetron capable of heating the ground food; In the food processor including a low temperature catalyst filter having a deodorizing action, the magnetron is capable of heating the food and the low temperature catalyst filter, to provide a food processor including a low temperature catalyst filter.

In addition, the food processor preferably further comprises a nozzle for supplying water to the low temperature catalyst filter.

Here, the food processor further includes a humidity sensor for checking the humidity of the low temperature catalyst filter, and when the humidity of the low temperature catalyst filter is lower than a predetermined humidity, the injection port is to supply water to the low temperature catalyst filter desirable.

In addition, the low temperature catalyst filter further includes a temperature sensor capable of measuring a temperature, the magnetron is preferably operated when the temperature of the low temperature catalyst filter is lower than a predetermined temperature. When the low temperature catalyst filter comprises a platinum coating, the predetermined temperature is particularly preferably 350 to 400 ° C.

The food processor may further include an inner container into which the food is put and a detachable portion formed at a lower portion thereof, wherein the grinder is located inside the inner container and is connected to a grinding motor outside the inner container through the detachable portion. desirable.

Here, it is preferable that the inner container can be mounted to the kitchen sink drain.

The food processor according to the present invention can prevent food residue from remaining on the inner wall of the drying furnace, thereby improving the reflection efficiency of the microwave and preventing odors.

In addition, it is possible to maintain the internal cleanliness and hygiene of the drying furnace, and to directly attach the food container to the kitchen sink, thereby reducing the inconvenience in use.

In addition, a separate heater for heating the low temperature catalyst filter is not required, thereby increasing the energy efficiency.
