Description

Food Waste Dryer {DRYING DEVICE FOR FOOD WASTE}

The present invention relates to a food waste dryer, and in particular, a container containing a food waste to be dried in a closed structure, the water discharged to the bottom surface of the container receiving portion is directly heated by a heater to evaporate, and the air is heated by the heater. Hot air is circulated to the front, rear, and bottom of the hot air circulating direction of the container housing to circulate the hot air as a whole, so that food waste can be dried quickly. It is discharged to the outside, the suction hole formed in the rear wall of the tube receiving portion is formed larger than the size of the inlet hole formed in the front wall, and the hot air flowing into the tube receiving portion from the tube receiving portion to the outside fan side than the hot air inflow flowing into the tube receiving portion by the operation of the fan. The amount of hot air resorption of the fan is increased so that a vacuum is generated in the tub container. It relates to a food waste dryer having an effect of preventing the smell from leaking, re-suctioning hot air blown by a fan, and reducing noise, and easily identifying a dry state by a transparent lid installed by a hinge on an upper part of the dryer body. .

The conventional food waste dryer includes a tub containing a food waste to be dried, a container housing for accommodating the barrel in the body of the food waste dryer, and a heater and a fan installed at the top of the body so as to supply hot air to the barrel placed in the container. fan).

However, in the conventional food waste dryer, since the air heated by the heater moves hot air from the upper part to the lower part by the operation of the fan, the surface of the food waste to be dried is well dried while the bottom part of the container is relatively There was a problem that it takes a long time to dry the food waste contained in the barrel because it is not dried well.

In addition, since the dry state of the food waste is not known from the outside, it is very inconvenient to use the food waste dryer because hot air is supplied for a long time to increase the waste of energy, and the hot air must be circulated again before being taken out before drying.

On the other hand, a heater may be installed in the lower part of the container housing for housing a container containing food waste, but in this case, hot air is not supplied directly to the container but heat is supplied only to the outside of the container, so that the food waste contained in the container evaporates. Drying was achieved by. Therefore, since the drying of food waste is carried out only by evaporation, the drying time of food waste was considerably time-consuming, and the waste of energy was very high because the evaporated air was discharged to the outside without reuse, and the noise generated at the time of discharge was very large. It caused inconvenience.

In addition, there was a problem in that the food waste dryer could not be manufactured compactly and compactly.

The present invention has been developed to solve the above problems, the inlet and suction holes are formed to circulate the air in the front and rear wall in the air flow direction of the container receiving portion where food waste is accommodated to circulate the air with less energy This is to provide a food waste dryer with reduced heat transfer costs and noise and reduced drying time.

Another object of the present invention is to provide a food waste dryer having a lid that can check the drying process without opening and closing the lid, as well as vacuuming the container receiving portion to prevent the odor generated during the drying process.

Food waste dryer of the present invention

A food waste dryer for drying food waste by circulating hot air while receiving a container for food waste to be dried,

It is formed in a closed structure in the lower part of the lid of the dryer body to accommodate the barrel containing the food waste to be dried, and the hot air circulation holes are formed in the front and rear walls in the air flow direction, respectively, and the bottom receiving portion is heated by the heater;

Fan installed in the lower part of the tube receiving portion to circulate the hot air to the hot air circulation hole formed in the front and rear walls of the tube receiving portion,

It is formed on the opposite side of the lid of the dryer body to discharge the moisture contained in the hot air moved by the fan, a hole is formed in the bottom surface in contact with the lower passage and the discharge hole is formed in the lid, the filter accommodating portion accommodated inside the filter,

This is accomplished by constructing a plurality of air inlets formed in the side of the dryer body on both sides of the fan back.

A bin containing dry food waste to be accommodated in the bin housing is achieved by opening the top, forming a plurality of air holes in the bottom and side, and forming a bridge so that the bottom is not in contact with the bottom surface of the bin housing.

In addition, the hot air is circulated by the fan and at the same time, the moisture contained in the circulated hot air is discharged through the filter accommodating part, while air is introduced into the dryer body through the suction hole formed in the lower side of the dryer body. Dry food waste,

Moisture discharged to the barrel accommodating portion is achieved by heating the bottom surface of the tub accommodating portion by a heater to cause evaporation.

In the food waste dryer of the present invention, the hot air is naturally circulated through the air holes formed in the wall of the air circulation direction in the container accommodating portion, and at the same time, the food waste is quickly dried by allowing the fan to re-intake the hot product. Has an effect.

In addition, the airtight container is sealed, but the size of the inlet and the inlet holes of the air holes in the airtight container is different, so that the airtight container is vacuumed, so that the odor generated during the drying process does not leak out through the lid. Has

In addition, since the hot air blown by the fan is re-suctioned from the tube receiving portion continuously, the hot air circulation is made naturally, thereby significantly reducing the operation noise generated during drying of food waste.

In addition, the lid is formed transparent to have the effect of visually checking the dry state without opening the lid.

An embodiment of a food waste dryer of the present invention will be described in detail with reference to the accompanying drawings.

Food waste dryer of the present invention is provided with a lid (2) on the top of the dryer body (1), the container receiving portion (3) to receive the container (7) containing the food waste in the lower portion of the lid (2) to be sealed Is formed in a sealed structure. The lid 2 positioned above the barrel container 3 is preferably made of a transparent material so that the dry state of the food residues of the barrel 7 accommodated in the barrel container 3 can be quickly identified with the naked eye. In addition, a transparent window (not shown) may be formed on the lid 2 so as to visually check the food waste of the barrel 7 accommodated in the barrel container 3.

In addition, the front and rear walls in the direction in which the hot air is circulated so that air flows to the front and rear of the barrel housing 3 in order to dry the food residue of the barrel 7 accommodated in the barrel housing 3 of the closed structure ( A plurality of holes are also formed in 4 and 5, respectively. Holes are not formed in the left and right walls in the direction in which the hot air is circulated. Here, the front wall 4 of the front and rear walls 4 and 5 is a wall located on the side where the fan 12 blows hot air, and the rear wall 5 is a direction in which the fan 12 sucks hot air. A wall located on the side. That is, when the fan 12 is operated, the fan 12 blowing side is the front wall 4 and the fan 12 suction side is the rear wall 5. In addition, since the hot air is sucked toward the fan 12 through the holes formed in the rear wall 5 among the holes formed in the front and rear walls 4 and 5, the hole formed in the rear wall 5 is called the suction hole 5-1. In addition, since the hot air of the fan 12 flows into the barrel accommodating part 3 through the hole formed in the front wall 4, the hole formed in the front wall 4 is called inflow hole 4-1.

It is preferable that the suction hole 5-1 has a hole formed in the rear wall 5 larger than the inlet hole 4-1 formed in the front wall 4. The vacuum is generated in the barrel accommodating part 3 due to such a difference in hole size. In other words, when the fan 12 is operated, the amount of air sucked into the fan 12 from the tube receiving portion 3 through the suction hole 5-1 of the tube receiving portion 3 is the inlet hole 4-1. Since the inlet flows into the barrel accommodating part 3 more than through, the cylinder accommodating part 3 is made into a vacuum state.

However, in order to prevent water from being discharged down the tub container 3 through the inlet and suction holes 4-1 and 5-1 formed in the front and rear walls 4 and 5, i.e. (3) No air circulation holes 4-1, 5-1 are formed to the bottom of the front and rear walls 4, 5 adjacent to the bottom surface so that moisture discharged from the food waste is collected on the bottom surface. For example, the front and rear walls 4 and 5 may have a thickness of 10 to 15 mm from the bottom surface of the container container 3 so that water discharged from the food waste contained in the container 7 does not flow out of the container container 3. It is preferable that no hole is formed up to the height.

The moisture 11 discharged to the bottom surface of the barrel container 3 is provided with a heater 11 on the bottom surface of the bottom surface of the barrel container 3.

In addition, a fan 12 is provided in a passage below the bottom surface so as to circulate the air whose temperature is raised by the heat generated by the heater 11. The fan 12 supplies hot air to the tub container 3 to dry the food waste, and then sucks the hot air from the tub container 3 and continues to circulate the vacuum. It serves to prevent the odor from leaking out of the barrel container (3) to the outside. In addition, the hot air containing steam and odors serves to move some hot air to the discharge filter accommodating part 9 so that the odor is removed by the filter.

Thus, the container 7 accommodated in the container receiving part 3 of the food waste dryer for drying food waste is a rectangular shape having an upper side inclined downward to open the food waste to be dried, and the bottom of this rectangular shape. A plurality of holes 7-1 are formed in the side and the side so as to be in contact with the hot air. In addition, a leg 8 is formed at the bottom of the cylinder 7 such that the bottom surface of the cylinder 7 is positioned at a predetermined height from the ground so that hot air passes through the bottom of the cylinder. Reference numeral 7-2 is a handle of the barrel (7).

The dryer body 1 of the food waste dryer has a plurality of discharge holes for installing a filter (not shown) on the other side of the lid 2 which opens and closes the barrel accommodating part 3 to discharge moisture contained in the hot air. 10-1) is provided with a filter lid 10, the lower portion of the filter lid 10, the filter receiving portion (9) for receiving a filter (not shown) separately from the barrel receiving portion (3) is the dryer body It is installed on one side of (1). The hole 9-1 is also provided in the bottom surface of the filter accommodating part 9 so that the hot air of the lower passage 14 circulated by the fan 12 may be discharged. As a filter (not shown) installed in the filter accommodating portion 9, a filter containing a component of activated carbon so as to effectively remove odor contained in hot air, or a filter composed of components effective for removing odor can be used.

The filter installed in the filter accommodation portion 9 serves to allow the water vapor contained in the hot air circulating through the barrel accommodation portion 3 to be discharged to the outside of the dryer body 1.

In addition, hot air is discharged through the filter on the lower sides of the opposite sides of the filter accommodating part 9, that is, the lower part of the dryer body 1 on both sides of the fan 12 behind the rear wall 5 of the tub accommodating part 3. The air suction hole 13 is installed so that air flows into the dryer body 1 from the outside of the dryer body 1.

The food waste dryer of the present invention configured as described above opens the lid 2 of the food waste to be dried (indicated by the dotted line in FIG. 1), and then puts the container 7 containing the food waste to be dried in the container container 3. The lid 2 is closed to seal the barrel container 3.

Water is discharged from the food waste of the container 7, which is enclosed in the sealed container container 3, through the hole 7-1 of the container 7 to the bottom surface of the container container 3. Gather.

Then, when the heater 11 installed at the bottom of the bottom of the container housing 3 is operated, and the fan 12 installed at the lower passage is operated, the heat generated by the heater 11 is transferred to the bottom 6 so that the bottom Moisture on the surface 6 is evaporated in the barrel accommodating part 3 while air (hot air) raised to a desired temperature by the heater flows out and flows out of the tub accommodating part by the fan 12, thereby circulating hot air. . That is, the hot air generated in the fan 12 is introduced into the barrel receiving part 3 through the inlet hole 4-1 of the front wall 4 located in front of the barrel receiving part 3 and the food waste. After contact with the food drier, the suction hole 5-1 of the rear wall 5 flows out of the barrel accommodating part 3 to be circulated to the lower passage 14.

At this time, since the suction hole 5-1 size of the sealed container accommodation portion 3 is larger than the size of the inlet hole 4-1, the suction hole ( Since the amount of air sucked out from 5-1) is blown by the fan to enter the inlet hole 4-1, the amount of air is reduced, so that a vacuum is applied to the barrel accommodating portion 3. Therefore, the odor is prevented from leaking to the lid 2 installed on the upper portion of the barrel container 3.

 As food waste is dried by circulation of hot air, the moisture contained in the hot air is discharged to the outside through the hole in the bottom of the filter accommodating part 9 on one side of the dryer body 1 and through the filter and the filter cap 10. Meanwhile, the outside air is sucked into the dryer body 1 through the air suction holes 13 formed at both sides of the rear of the fan.

The food waste dryer according to the present invention has a container structure 3 in a sealed structure, and allows the bottom surface to be heated, and at the same time, the front and rear walls 4 and 5 and the bottom 8 of the container 7 are bottomed. Hot air is also circulated on the bottom of the cylinder 3 which is separated from the surface 6 to the top. Accordingly, the hot air passes through the upper, lower, and side surfaces of the barrel 7 accommodated in the barrel accommodating part 3 to be brought into contact with the food dregs, thereby quickly drying the food dregs contained in the tub 7, thereby shortening the drying time. do.

As the process of re-absorbing the hot air blown by the fan 12 from the barrel receiving portion 3 is naturally performed continuously, the operation noise generated during drying is greatly reduced.

In addition, the moisture and smell of the food waste are heat-oxidized and burned by heat drying and discharged to the outside of the dryer body 1 through the filter, thereby preventing inadvertent leakage of the smell generated during drying.

In addition, the lid 2 to be opened and closed is made of a transparent material, it is possible to directly check the dry state of the food waste through the lid (2).

Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the claims, the detailed description of the invention, and the accompanying drawings, and such modifications may be made. Naturally, variations and the like fall within the scope of the present invention.
