Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a kitchen waste processing device, and particularly to a kitchen waste processing device that heats and dries kitchen waste.

[Background of the invention]

An example of an apparatus for heating and drying kitchen waste is the one described in Japanese Patent Publication No. 59-36181, which reduces the pressure in a sealed container after the kitchen waste is put in, and heats the container using a heater. Accordingly, there are known devices configured to dry kitchen waste in a container.

This device uses a heater to heat the kitchen waste, so
! ! ! There is a problem in effectively removing moisture from the inside of the quart in a shorter period of time.

RI Akira's purpose] The uninvented purpose is to provide a kitchen waste 11] device that can effectively remove moisture from the inside of kitchen waste in a shorter time by irradiating the food waste with microwaves and heating it. It's about doing.

[Summary of the invention]

The present invention is characterized in that it is equipped with a container into which kitchen waste is thrown and a microwave heating device that heats the kitchen waste, and the kitchen waste is heated by irradiating the kitchen waste with microwaves. .

[Embodiments of the invention]

An embodiment of the present invention will be explained with reference to FIG. 1 and FIG. 9J2.

In Figure 1g1, the container 10 has a kitchen waste inlet 11 at its top. A fi 21 provided with a handle is attached to the container 10 so as to be able to open and close the kitchen waste inlet 11. The exhaust system has a weight of 10 times outside the container.

One end of the intake pipe 31 communicates with the inside of the container 10 and is connected to the side wall of the container 10, and the other end is used for exhaust! It is connected to the intake port of ll130. One end of the exhaust pipe is connected to the exhaust port of the exhaust system, and the other end is opened to the atmosphere, for example.The microwave heating system is installed outside the container 10, and in this case, the second It is provided in the container 10 as shown in the figure.

In FIG. 2, a microwave passage opening is formed in the container 10, in this case the side wall. The magnetron receiver 41 of the microwave heating device [40] corresponds to the microwave passage hole and is attached to the container 10 via the microwave passage window 13. The microwave passage window is made of a material that has heat resistance and pressure resistance (negative pressure) and transmits microwaves, such as heat-resistant glass. Microwave passing window 13
The window frame is attached to the window frame while maintaining airtightness with a sealing material 14 made of silicon, for example. Seven flanges 16 are provided around the micro-liquid passage holder, and the window frame 14 is airtightly sandwiched between the flange 16 and the flange housing of the magnetron receiver 41. The microwave main body 4 is provided outside the magnetron receiver 41, and the antenna material is made to protrude into the magnetron receiver 41.

In FIGS. 1 and 2, N21 is opened and kitchen waste is put into the container 10 through the kitchen waste inlet 11.

Thereafter, 1i21 is closed and the inside of the container 10 is hermetically sealed. In this state, exhaust bag W! The operation of I is started, and the inside of the container IO is evacuated under reduced pressure. Thereafter, microwaves are irradiated from the microwave heating device @ψ through the microwave passing window 13 and the micro liquid passage space between the kitchen wastes, thereby heating the kitchen waste space. In this case, the kitchen waste is heated and dried under reduced pressure. For example, during this process, a temperature sensor (not shown) detects that the temperature of the steam between the kitchen wastes (or the temperature of the steam generated from the kitchen wastes) has reached the set temperature (for example, the temperature below the ignition temperature between the kitchen wastes). The operation of turning off the microwave heating device is stopped when this is detected, and the operation of turning off the microwave heating device is then restarted when the temperature of the kitchen waste falls below the set temperature. Such operations are repeated until the kitchen waste is sufficiently dry.

In this embodiment, the following effects can be obtained.

(1) Since the kitchen waste is heated by irradiating it with microwaves, the moisture inside the kitchen waste can be effectively removed in a shorter time.

(2) Since the operation of the microwave heating device is turned on and off depending on the temperature of the kitchen waste, it is possible to prevent the kitchen waste from overheating and prevent the kitchen waste from burning during the drying process.

(3) Since the kitchen waste is heated under reduced pressure, the drying efficiency of the kitchen waste is further improved.

In this embodiment, the kitchen waste is irradiated with microwaves under reduced pressure, but the microwaves may simply be irradiated.

Chestnuts [Effects of the Invention] As explained above, the present invention heats kitchen waste by irradiating it with microwaves, thereby making it possible to effectively remove water inside the kitchen waste in a shorter time. There is an effect that it can be done.
