Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is applicable to kitchens of restaurants, hotels, inns, etc.
This is a kitchen waste processing device that hygienically processes kitchen waste, which is the raw garbage generated in home kitchens.In particular, it hygienically removes only the moisture contained in kitchen waste, making it easier to handle the kitchen waste after it is processed. The present invention relates to a kitchen waste processing device for processing.

[Prior Art] Conventionally, this type of kitchen waste processing apparatus has pulverized kitchen waste and then dehydrated it by centrifugal separation or a screw press. In conventional kitchen waste processing equipment, the kitchen waste is crushed, so the screen of the centrifuge or screw press is often clogged with rice grains in the kitchen waste, resulting in a significant drop in dewatering performance, resulting in practical problems. There was a problem. Therefore, in Japan, kitchen waste is generally not processed in any way, but simply drained of a small amount of water, placed in a plastic bag or plastic container, and disposed of by local government garbage collectors or garbage disposal companies. Therefore, the actual situation is that garbage is stored until it is collected. Garbage, including kitchen waste, is stored in and around the place where the garbage is generated, and there are hygienic problems such as bad odors being generated until the garbage is collected. Especially in the customer service industry such as restaurants, hotels, and inns.
This odor problem is important and could lead to commercial problems. In addition, kitchen waste has a high moisture content and is swollen, making it inconvenient to handle, resulting in high transportation costs and high final disposal costs such as incineration.

As a kitchen waste processing device to solve such problems,
The present inventors proposed a kitchen waste processing device that dries kitchen waste using high-temperature gas, and the same applicant previously filed an application.

FIG. 4 is a schematic configuration diagram for explaining the principle of the kitchen waste processing apparatus of the prior application.

In the figure, (1) is a container that stores kitchen waste, (2) is a blower that circulates and supplies gas to the container (1) that stores this kitchen waste, (3) is a heating device that heats the gas, and (4) is a container(
1) and the blower (2) *v! , (5) is the blower (
A conduit (6) connects the heating device (2) and the heating device (3), and a pipe (6) connects the heating device (3) and the container (1). Container (1)
, a blower (2), and a heating device 1 (3) to a conduit (4),
(5) and (6) are connected in an annular manner to form a circulation path, and the structure is such that high-temperature gas circulates. (7) is a branch path for taking out part of the gas circulating in this circulation path, (8) is a dishwashing sink, and (9) is this sink (8).
The drain pipe (10) attached to the drain pipe (9) is a water seal provided in the drain pipe (9).

The operation of the kitchen waste processing apparatus of the prior application constructed in this way will be explained.

When a predetermined amount of kitchen waste is stored in the container (1), the blower (2) is operated, and the heating device (3) is operated, the gas (initially air) in the circulation path is heated and raised by the heating device (3). The warmed bales are fed to the container (1) through the conduit (6),
), the waste is heated and heated to evaporate part of the moisture in the waste, and then circulated and supplied to the heating device (3) again by the air blower I (2). When the gas is circulated and supplied in this way and the temperature rising-evaporation process is repeated, the temperature of the gas circulating in the circulation path gradually rises and its volume increases. In addition, since water vapor is generated in proportion to the amount of water evaporated from kitchen waste,
This also increases the volume of gas in the circulation path. The gas whose volume has increased is 11! of the circulation path! (4) is discharged into a drain pipe (9) through a branch (7). Drain pipe (
Since the pressure in the drain (9) is normally equal to atmospheric pressure, the pressure of the gas in the circuit also balances with the pressure in the drain (9) and remains essentially at atmospheric pressure. The gas in the circulation path is
At the beginning of operation, it is air, but as time passes and the temperature of the kitchen waste increases, water vapor is generated one after another, so the air that was initially present in the circulation path is gradually replaced by water vapor. Eventually, substantially only water vapor will circulate within the circulation path. Then, an amount of water vapor corresponding to the newly generated water vapor is pushed out into the drain pipe (7) through the branch path (7). Since the temperature of the drain pipe (9) is low, the water vapor pushed out through the branch path (7) condenses into water in the drain pipe (9) and is drained. In this way, the moisture in the kitchen waste is removed and the kitchen waste is dried.

When the drying of the kitchen waste progresses sufficiently and the amount of water vapor generated from the kitchen waste decreases, the temperature of the kitchen waste begins to rise significantly, so this state is detected and the operation of the heating bag gt (3) is stopped, When the temperature of the kitchen waste has dropped sufficiently, the operation of the blower is stopped and the dried kitchen waste is taken out.

[Image problem to be solved by the invention] Since the kitchen waste processing device of the prior application is configured as described above, the circulation path is sufficiently kept warm by the heat insulating material in order to reduce heat loss due to heat radiation from the circulation path. If the drying process is carried out later, the drying process of the kitchen waste becomes faster, but there is a problem that the temperature of the kitchen waste after the drying process is difficult to lower. Additionally, in this kitchen waste processing device, there is a problem in that the water vapor that occupied the circulation path and the branch path when the drying processing device is finished condenses on the surface of the kitchen waste as the temperature of the kitchen waste decreases, reducing the degree of dryness of the kitchen waste. Ta.

This invention was made in order to solve the above-mentioned problems, and is a kitchen waste processing device that can rapidly cool high temperature kitchen waste after drying in a heated steam circulation type kitchen waste processing device. The purpose is to provide equipment.

[Means for Solving the Problems] The kitchen waste processing apparatus according to the present invention includes a suction fan for sucking gas into the circulation path in a branch path of a high-temperature gas circulation path, and a suction fan for sucking gas into the circulation path after drying treatment. Make sure to suck out the gas inside and quickly replace it with outside air. Furthermore, if necessary, an intake pipe for introducing outside air into the high-temperature gas circulation path is provided in the conduit forming the IrR path. Note that if the container for storing kitchen waste is equipped with a drain pipe, the drain pipe can have the function of an intake pipe for taking in outside air, so there is no need to provide an intake pipe in the conduit.

[Function] Therefore, in the kitchen waste processing apparatus of the present invention, the water vapor, which is a hot gas, existing in the circulation path after the drying process of kitchen waste is removed by the suction fan provided in the branch path of the high-temperature gas circulation path. It is quickly replaced with outside air, and the temperature of the kitchen waste decreases rapidly.

[Example] Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic configuration diagram for explaining the principle of the kitchen waste processing apparatus of the present invention.

In the figure, (1) is a container that stores kitchen waste, (2) is a blower that circulates gas to the container (1) that stores this kitchen waste, (3) is a heating device that heats the gas, and (4) is 11
A conduit connecting 1 (1) and the blower (2), (5) is the blower Ji

) and the heating bag ff1(3) are tied together in a ring to form a circulation path, so that the high temperature gas is circulated. (7) is a branch path for taking out part of the gas circulating in this circulation path, (8) is a dish washing sink, (9) is a drain pipe attached to this sink (8), (10) is a water seal provided in this drain pipe. (11) is an intake pipe for taking in air, (12) is a valve, (13)
is a gas suction device consisting of a suction fan for suctioning high temperature gas after drying from a circulation path. This suction fan (13) is provided in a branch (7) connected to a conduit (4) forming a circulation path.

The operation of the kitchen waste processing apparatus configured as described above will be explained.

Close the valve (12) of the intake pipe (11) and turn on the suction fan (
13) is stopped, a predetermined amount of kitchen waste is stored in the container (1), the air blower 111 (2> is operated, and the heating device (3)
to start drying the kitchen waste. That is, kitchen waste is stored in a container (1), one transporter (2), and a heating bag N (
3), the gas in the circulation path is heated to the heating bag M(3).
After heating and raising the temperature, the container (1) is passed through the conduit (6).
will be sent to The heated gas comes into contact with the kitchen waste in the container (1), heats the kitchen waste to raise its temperature, evaporates part of the water in the kitchen waste, and circulates. The water is heated to a raised temperature and then circulated to the container (1). When the gas is thus circulated and fed to the container (1) containing kitchen waste and the temperature raising-evaporation process is repeated, the temperature of the gas circulating through the circulation path gradually rises and its volume increases. Further, in the container (1), water vapor is generated in proportion to the amount of water evaporated from the kitchen waste, and this also increases the volume of gas in the circulation path. The gas whose volume has increased is discharged into the drain pipe (9) through a branch (7) provided in the conduit (4) of the circulation path by the amount of the increase. this is,
This is because the pressure in the drain pipe (9) is equal to atmospheric pressure, so the pressure of the gas in the circulation path is also balanced with the pressure in the drain pipe (9) and remains substantially at atmospheric pressure. The gas in the circulation path is air at the start of operation, but as the temperature of the kitchen waste increases over time, water vapor is generated one after another, so the air that was initially in the circulation path is is gradually replaced by water vapor, until essentially only water vapor is circulating in the circuit. and,
Subsequently, an amount of water vapor corresponding to the newly generated water vapor is forced out through the branch (7) into the drain pipe (7). In the drain pipe (9), since the temperature inside is low, it condenses into water and is drained. In this way, the moisture in the kitchen waste is removed, and the drying of the kitchen waste progresses. When the drying of the kitchen waste progresses sufficiently and the amount of water vapor generated from the kitchen waste decreases, the temperature of the kitchen waste begins to rise significantly, so this condition is detected and the operation of the heating device (3) is stopped. Lower the temperature of the heating device (3).

Next, the air blower 111(2) is stopped, the pulp (12) of the intake pipe (11) is opened, and the suction fan (13) is activated. In this case, the valve (12) may be opened and the suction fan (13) may be operated while the blower (2) is left operating without being stopped.

In any case, by operating the suction fan (13), the water vapor in the circulation path and the branch path is immediately replaced by the air taken in from the intake pipe (11), so the container (1)
The temperature of the kitchen waste inside the container drops rapidly. Therefore, the problem that water vapor condenses on the surface of the kitchen waste after the drying process of the kitchen waste and the dryness of the kitchen waste decreases does not occur.

The dried kitchen waste obtained in this way is sufficiently dehydrated, its weight has been significantly reduced, and it does not generate any bad odor even if left as is, making it easy to handle and hygienic. It becomes.

In addition, in the embodiment shown in FIG. 1, the branch passage (7) is connected at one end to the conduit (4) and at the other end to the drain pipe (9) of the dishwashing sink (8). However, the other end of this branch path (7) may be open to the atmosphere.

In this case, by providing a condenser in the branch path (7),
There is no longer any steam spewing out from the branch path, and the problem of kitchen waste odor dissipation does not occur. Furthermore, even if the branch passage (7) is connected to the drain pipe (9) as in the embodiment shown in FIG. ), and the pressure inside the drain pipe (9) hardly increases, and the temperature of the drain pipe also does not rise, so a favorable condition can be obtained.

Every time kitchen waste occurs, remove the lid (22) from the bottom of the sink (8).
1 (24) through the input/output port (23). Since the drain pipe (26) is connected downstream of the water seal part of the drain pipe of the sink (8), water dripping from the kitchen waste is discharged to the drain pipe of the sink through the drain pipe (26).

After storing a predetermined amount of kitchen waste in 1II (24) of the kitchen waste container (1) and thoroughly draining the water from the kitchen waste,! (22) and the valve (33) provided in the drain pipe (26) are closed and operated as described in the explanation of FIG. 1 to dry the kitchen waste. After the drying process is finished, open the lid (22) and
4) Take out the processed kitchen waste inside and dispose of it all together. The kitchen waste treated in this way is sufficiently dehydrated, its ff1ffi is greatly reduced, and even if it is left as it is, it does not generate any bad odor, so it is easy to handle and sanitary. Furthermore, since the kitchen waste disposal device of this embodiment has the kitchen waste inlet at the bottom of the sink, it is close to the place where the kitchen waste is generated and is convenient for handling.

FIG. 3 shows a kitchen waste container (
Another example of 1) is shown below. The figure is a sectional view of the kitchen waste container (1). The kitchen waste container of the embodiment shown in Fig. 2 has a simple wire mesh (

In this case, kitchen waste will not appear on the sink again, allowing for more hygienic disposal.

By the way, there are no particular restrictions on the heating device N(3), which is an element of ζJ used in the kitchen waste processing apparatus of the present invention, and its usage, as long as it can simply heat the circulating gas. Usually, an electric heater is installed in the gas circulation path to directly heat the circulating gas, but a method of indirectly heating the circulating gas from outside the circulation path using a gas burner may also be used. The capacity of the heating device and the flow rate of circulating gas are based on the kitchen waste container (1
) capacity, required drying speed, heat retention characteristics of the circulation path, etc. There are no particular restrictions on the type of condenser to be provided in the branch path (7), if necessary, and it is usually sufficient to use a condenser with good heat dissipation properties, such as by narrowing the gas passage and providing fins.

Further, the blower, which is another element used in the kitchen waste processing apparatus of the present invention, may be a normal fan, and as a gas circulation device, the blower is used for supplying high-temperature gas. It is preferable to provide it on the inlet side of the device from the viewpoint of heat resistance of the blower.

In the embodiment shown in FIGS. 3 and 4, the drain pipe (26) is attached to the garbage container (1) that forms part of the circulation path, so the intake pipe (11) is attached to this drain pipe. It can have a function.

Therefore, if the kitchen waste container (1) is equipped with a drain pipe, there is no particular need to provide an intake pipe (11).

[Effects of the Invention] As explained above, the kitchen waste processing apparatus of the present invention includes a branch path provided in a high-temperature gas circulation path for drying kitchen waste.
A suction fan is installed to suck the gas in the circulation path, so the high-temperature gas in the circulation path after drying is sucked out by the suction fan and quickly replaced with air introduced from the intake pipe or drain pipe. be able to. Therefore, the water vapor present in the circulation path etc. can be immediately replaced with air after the kitchen waste drying process, and the kitchen waste can be quickly processed while preventing the water vapor from condensing on the surface of the kitchen waste, resulting in a practical kitchen waste processing apparatus.
