Description

Food Garbage Disposer having Low Temperature Catalyst

The present invention relates to a food processor provided with a low temperature catalyst, and more particularly, to a food processor equipped with a low temperature catalyst capable of efficiently deodorizing function by using heat generated in a drying furnace where food is dried. will be.

In general, a certain amount of residue (waste food) is discharged from each home or restaurant every day, and the residue is used as a livestock feed or filtered through a simple strainer and then discarded. This residue treatment method increases the amount of waste, and if the waste is not thrown away frequently, it causes odors and pollutes the surrounding air.

In recent years, efforts have been made to reduce food waste at homes and restaurants, but it is difficult to control the amount of garbage that is gradually increasing, and when it is reclaimed, landfill sites are limited, as well as odor and leachate. Environmental damage caused by the situation was very serious.

Therefore, in recent years, the government has implemented a waste-based tax system, and the government has also mandated that a treatment device that can induce food, such as fermentation, drying, or extinguishing, must be mandatory when newly built for each group meal or apartment complex. .

However, the food waste contains about 80 ~ 90% of moisture, and in order to reduce the amount of food waste, it is processed through the process of drying and fermentation by heating, microbial reaction, etc. At this time, a large amount of moisture and high concentration of odor are generated. Resolving this presents another challenge.

The odor component that is usually generated in the food processor generates various kinds of gases, and the gas composition varies depending on the type of food, the length of the food, the treatment period, and the processing temperature, resulting in decay or abnormal fermentation, that is, anaerobic fermentation. In some cases, a large amount of toxic odorous gas can be released, which can harm the human body.

This is due to the formation of anaerobic conditions in the course of continuous processing of food waste, the more severe odor is generated, the gas providing the cause of the odor generated at this time can be largely separated into acid, neutral, basic. Examples of acidic gases include hydrogen sulfide and methyl mercaptan. Basic gases include ammonia and trimethylamine, and neutral gases include methyl sulfide, methyl disulfide, and acetaldehyde.

These odorous gases are harmful to the human body, cause air and environmental pollution, and give a disgust to the surrounding facilities.

Food wastes containing a lot of moisture are easily rotted if they are left as it is, causing odors and harming the surrounding sanitary environment.Many companies have tried to develop technology for the treatment of hot air circulation drying method for processing food waste in homes and restaurants. Launched food processor products using various methods such as hot air circulation drying method with agitation function, hot air circulation drying method with agitation function and crushing function, simultaneous use of agitation function and microorganisms, and refrigerated storage. Has come.

Likewise, citizens' awareness about the discharge after the disposal of food waste is increasing, but not only dehydration performance but also complex problems such as sewage pollution, air pollution, noise generation, maintenance cost, production cost, convenience of use, installation and resource recycling There is no product that can be solved.

In the conventional food processor, the air passing through the inside of the food processor passes through a separate deodorizing device installed outside or passes through the deodorizing unit in order to remove the odor of the generated food has a process of removing the odor.

Deodorization methods include adsorption and decomposition using carbon, carbon components, or zeolites, or photocatalysts. However, in the above cases, regeneration and exchange are necessary in terms of lifespan. There is a problem with the cost.

In the conventional method, the heat generated from the hot plate installed in the drying furnace is used only to dry the food waste, and the used heat is thrown out through the exhaust port as it is.

In order to deodorize the odor, the deodorizer installed outside the drying furnace has a disadvantage in that additional energy is required because a structure in which high temperature heat is applied to a separate power supply. In addition, the deodorizing unit installed inside the drying furnace adsorbs the odor using a deodorant, but the use life is short and the deodorizing performance is poor.

One section of the food processor.

1 and 2, the food processor 100 equipped with a low temperature catalyst according to an embodiment of the present invention has a container-shaped main body provided with a heating device 115 at an inner lower surface thereof to heat the injected food. 110, a cover 120 detachably installed on the upper portion of the main body 110, provided with an inlet 124 and an exhaust port 127 so that air flows, and installed inside the main body 110 to accommodate food. It is provided between the drying barrel 130, the main body 110 and the drying barrel 130, the heat transfer body 140 for transferring the heat generated from the heating device 115 to the drying barrel 130, and deodorizing means ( 150).

The body 110 may have a cylindrical or polyhedral container shape. The lower or side surface of the main body 110 is formed of a heat resistant material having a predetermined thickness. The main body 110 is made of a heat-resistant material that can withstand high temperatures since it is exposed to the input heat when removing moisture by applying heat to food waste. For example, a thermosetting resin or the like can be used.

The heating device 115 may be provided with a heating plate or a heating wire, which will be described as a heating plate in the embodiment of the present invention. As the heating device 115, a heater using electricity or gas may be used. In particular, PTC heaters, coil heaters, and seed heaters may be used. Due to the operation of the heating device 115, the lower surface of the main body 110 is heated, and heat may be transferred to another container or material by the heat transfer unit 140 provided inside the main body 110.

Meanwhile. The heating device 115 may also be provided as a hot air device in order to blow high temperature air into the drying container 130, it is possible to supply heat even without the help of a separate heat carrier (140). The heating apparatus using the hot air is not limited between the main body 110 and the drying container 130, so that only the hot air can be supplied, so that the heating apparatus can be variously arranged.

The heating device 115 may be connected by a power supply unit (not shown) and a bimetal (not shown). Bimetal refers to a rod-shaped part made by superimposing two kinds of thin metal plates having very different thermal expansion coefficients. If the heating device 115 is above a certain temperature, the bimetal is activated to release the contact with the power supply unit (not shown). If the heating device 115 is below the predetermined temperature, the bimetal is returned to the original state, so the power supply unit is not shown. Will be in contact with That is, the bimetal serves to block the power supplied to the heating device 115 when the temperature of the heating device 115 rises sharply. The heating device 115 may be installed on the side surface of the main body 110 and may be formed widely along the shape of the main body 110.

The inner surface of the main body 110 or the inner surface of the cover 120 is provided with a temperature sensor 117, the display unit so that the temperature measured by the temperature sensor 117 can be displayed on the outer surface of the main body 110 118 is provided. As the display unit 118, a liquid crystal display device may be mainly used. Thus, the user can check the internal temperature of the main body 110 in real time.

Although not shown in FIG. 1 or FIG. 2, a control unit (not shown) that is connected to the temperature sensor 117 or the heating device 115 to control the temperature inside the main body 110 may be further provided. That is, the controller (not shown) may operate or stop the heating device 115 by comparing the temperature inside the main body 110 measured by the temperature sensor 117 with the desired operating temperature. Usually, the control unit may maintain the temperature of the heating apparatus 115 at a constant 150 to 200 ° C. Of course, in this case, it is preferable that an operation unit is further provided on an outer surface of the main body 110 so that a user sets a desired temperature through a control unit (not shown).

The cover 120 is installed on the upper portion of the main body 110, and the inlet port 124 and the exhaust port 127 are provided to allow air to flow between the inside and the outside of the main body 110.

The intake port 124 is composed of an intake hole 122 formed in the cover 120 and an intake fan 123 provided near the intake hole 122. Intake port 124 may be provided on the upper surface or the side of the cover (120). In the present embodiment, a state in which the intake port 124 is provided on the upper surface of the cover 120 will be described.

The intake hole 122 is sufficient to allow sufficient air to pass therethrough, and thus may be a plurality of small holes. Intake fan 123 is a device for sucking air from the outside to the inside of the main body 110, the air introduced into the main body 110 by the intake fan 123 moves along the lower side of the main body 110 Done. At this time, since the lower surface of the main body 110 is heated by the heating device 115, the injected air is transferred to the upper direction of the main body 110 receives heat.

The exhaust port 127 includes an exhaust pipe 125 formed to penetrate a space from the inner lower surface of the cover 120 to the outer side surface and an exhaust fan 126 provided on a path of the exhaust pipe 125. The exhaust pipe 125 serves to discharge the air heated inside the body 110 to the outside. As long as the heated air is discharged, it can be composed of several narrow tubes. The exhaust fan 126 forcibly sucks the air inside the main body 110 so that the air inside the main body 110 easily passes through the exhaust pipe 125 and is discharged to the outside.

Of course, the exhaust port 127 may be provided on the side of the main body 110 or the cover 120.

Since the intake fan 123 and the exhaust fan 126 are in contact with the air at a high flow rate, the intake fan 123 and the exhaust fan 126 may be made of a wear resistant material.

Drying container 130 is installed inside the main body 110 serves to accommodate food waste. When the food waste is directly contained in the main body 110, the food waste heated by the heating device 115 provided on the inner lower surface of the main body 110 may be pressed onto the inner surface of the main body 110, and the main body 110 may be attached. There is a risk that the inner surface of the machine will be easily damaged. Therefore, there is a need for a drying container 130 that can contain and process food waste separately. The drying container 130 may have a polyhedron or cylindrical container shape like the main body 110.

The drying container 130 may be formed of aluminum having high thermal conductivity, or may be formed of another metal having high thermal conductivity. In addition, a Tefron coating may be applied to protect the surface of the drying container 130 and to prevent food water from sticking.

The heat transfer body 140 is provided between the main body 110 and the drying vessel 130 to transfer heat generated from the heating device 115 to the drying vessel 130. The heat transfer body 140 may vary in shape depending on the shape of the drying vessel 130, and generally has a plate shape made of a material such as copper or silver. Both copper and silver have good thermal conductivity, but there is a difference in price, so they can be selected in consideration of manufacturing cost, and other materials having excellent thermal conductivity may be used.

The heat transfer body 140 may have a perfect plate shape or a plate shape having a hole formed at a central portion thereof. If a part other than the heat transfer body 140 is added between the main body 110 and the drying container 130, a plate having a hole formed in the center portion will be used.

The body 110 and the cover 120 is preferably made of a heat resistant material such as a thermosetting resin. It is to be made of a material that is not easily deformed since it is supplied with continuous heat by the heater 115.

Referring again to FIGS. 1 and 2, the deodorizing means 150 may be disposed inside the exhaust port 127 as one embodiment. Since the exhaust port 127 is an outlet through which the gas circulated inside the food processor 100 is finally discharged, the exhaust port 127 may be subjected to a deodorization process for all of the gas without missing gas.

The deodorizing means 150 may have a structure in which the low temperature catalyst 154 surrounds the heating rod 152 having a predetermined cross section. That is, as an example, the heating rod 152 may be formed in a cylindrical shape, and the heat rod 152 is further protruded at both ends of the low temperature catalyst 154 so that heat is more effectively transmitted to the heating rod 152. Can be. The heating rod 152 may be supplied with a separate power source.

The low temperature catalyst 154 may react even at a low temperature of the exhaust gas because the low temperature catalyst 154 has superior removal performance at a low temperature, and thus, a separate heating means may not be required. In general, the low temperature catalyst 154 is excellent in the technical features to be able to operate normally even in a temperature environment of 350 ℃ or less at room temperature. Preferably, operating in a temperature environment at 100 ° C. or higher and 250 ° C. or lower is effective in achieving the function of the low temperature catalyst. The room temperature may be defined as generally referring to a temperature of about 25 ° C., and a temperature representing a room temperature may be changed according to an environment.

In addition, the use of a small amount of catalyst has an excellent contaminant removal performance has the advantage of minimizing the catalyst installation space.

In the heating rod 152, heat is transferred to the heating rod 152 and the low temperature catalyst 154 by the exhaust gas from the food waste while the heating apparatus 115 is operated, and the heating rod 152 is transferred. The heat can be supplied to the low temperature catalyst 154 without any heat loss. Here, a heat transfer member such as a thermal pad may be interposed between the heating rod 152 and the low temperature catalyst 154 to enable smooth heat transfer.

On the other hand, since the heat supply is not made to the exhaust gas generated from the food waste in the state in which the heating device 115 is stopped, heat transfer to the deodorizing means 150 becomes difficult. In the above case, since there is a risk that the odor of the food processor remaining inside and outside the drying container 130 may remain, power is separately supplied to the heating rod 152 to generate heat by force.

The low temperature catalyst 154 may function as an adsorbent itself and may catalyze without causing incidental pollution to the environment. Like photocatalysts, there is no need for stringent requirements such as deodorizing filter nets and the ability to catalyze even at ambient temperatures. In addition, the low temperature catalyst 154 exhibits a good effect on H ₂ S (hydrogen sulfide) and HCHO (formaldehyde), there is an advantage that can be purified for a long time.

In the low temperature catalyst 154 applied to the present invention, since the average particle size may be formed as small as 5 nanometers (5 * 10 ^-9 m), it may be possible to efficiently cope with adsorption of fine dust. In other words, the conventional photocatalyst has a particle size of about 10 to 40 nanometers, so that the particles can be formed to be much smaller, thus exhibiting an excellent effect on removing fine dust.

Existing photocatalysts require ultraviolet rays such as sunlight or UV lamps, so we have to provide sunlight or other light sources during actual use.However, our living spaces do not necessarily meet these conditions, but photocatalysts exhibit limited efficiency. The low temperature catalyst of the present invention does not require the presence of a separate light source, so there is an advantage that the restrictions on use are reduced. In addition, the low temperature catalyst 154 may be a non-photocatalyst (cancer catalyst) which performs catalytic activity even in a space lacking ultraviolet rays or in a field of non-ultraviolet rays, a sink, a shoe rack, a chest of drawers, and the like.

The air heated by the heating device 115 in the lower side inside the main body 110 is moved to the top of the main body 110 by the air convection principle that the warm air rises upward. That is, the air introduced into the drying container 130 through the inlet 124 from the outside is exhausted after the process of circulating in the drying container 130 in the state containing the odor gas and water vapor generated from food waste ( 126 is transferred to the deodorizing means 150 with the help of.

Referring to Fig. 3, there is shown an application state as another embodiment 150 'of the deodorizing means applied to the present invention. Deodorizing means 150 'is composed of a ring-shaped heating rod 152' and a low temperature catalyst 154 'covering the heating rod 152' in the form of a coating, which surrounds the upper inner circumferential surface of the drying vessel 130. It can be arranged as. Since the outer surface of the drying container 130 is thermally connected to the heating device 115, the food container 200 always maintains a high temperature thermal state in a state where the food processor 200 is operated.

As described above, the deodorizing means 150 ′ maintains a state in which the deodorizing means 150 ′ is in close contact with the drying container 130, thereby providing a structure capable of constantly receiving heat from the drying container 130. That is, in the state in which the food processor 100 operates, the drying bin 130 maintains a predetermined temperature or more so that the heat of the drying bin 130 is prevented from dissipating uselessly and deodorizing means so that heat can be efficiently used. 150 'may be in direct contact with the drying container 130.

The heating rod 152 'may be connected to an external power source to separately generate heat. The heating rod 152 ′ serves to reduce heat loss by receiving heat transmitted to the low temperature catalyst 154 ′.

Looking at the deodorizing means 150 ′, the deodorizing gas is naturally deodorized in the process of moving along the inner wall surface of the drying container 130 in the process of raising the odor gas generated in the drying container 130 to a high temperature state. Inside the drying barrel 130, a duct (not shown) or a blowing fan may be additionally installed to guide the gas at the center portion to the upper side of the inner circumferential surface.

The deodorizing means 150 and 150 ′ described above may be disposed at any position as long as the deodorizing means 150 or 150 ′ is not limited to the position described in the above embodiment but may use the heat generated from the heated drying barrel 130. For example, the heat supply may be continuously provided from the drying container 130 by being disposed in close contact with the lower surface or the side surface of the drying container 130.

While preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described specific embodiments. That is, those skilled in the art to which the present invention pertains can make many changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications are possible. Equivalents should be considered to be within the scope of the present invention.
