Description

DEODORIZATION APPARATUS OF FOOD AND DRINK TREATMENT}

The present invention relates to a deodorizing apparatus of a food waste treatment machine, and more particularly, to a high temperature for purifying a large amount of odor generated in a household device such as a food waste treatment machine for treating waste food or an industrial device for thermally and chemically treating various materials. A deodorizing apparatus for a food waste treatment system having a catalyst processing apparatus and a low temperature odor removing apparatus at the same time.

Generally, each household or restaurant discharges a certain amount of residue (disposal food) daily, and these residues are used as livestock feeds or simply filtered through a simple screen to filter out the mixed water. The waste disposal method increases the amount of garbage, and if the garbage is not frequently discarded, a malodor is generated to pollute 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. Environmental damage has been 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 water. In order to reduce the amount of food waste, it is dried and fermented through heating, microbial reaction, etc., but a large amount of water and a high concentration of odor are generated Solving this has created another task.

Generally, malodorous components generated in the food waste treatment system are caused by various kinds of gases, and the composition of the gas varies depending on the type of food, the period of time left, the treatment temperature, etc. and the corruption or abnormal fermentation, that is, anaerobic fermentation In this case, it releases a large amount of noxious odorous gas which can harm 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 the acidic gas include hydrogen sulfide and methyl mercaptan. Examples of the basic gas include ammonia and trimethylamine. Examples of the neutral gas include methyl sulfide, methyl disulfide, and acetaldehyde.

These odorous gases are harmful to the human body, cause air and environmental pollution, and have aversion to the surrounding facilities.

As a countermeasure against this, activated carbon adsorption, chemical liquid cleaning, microbial deodorization and ozone oxidation have been devised.

However, these methods were difficult to completely remove the high concentration complex gas containing a large amount of moisture generated in the food processor in a certain time.

So, the deodorization technology of the existing food processor to solve this problem is designed to force the odor-producing substance to be exhausted through the sewer pipe by installing it in the sink, or in the high temperature drying method, catalysts such as platinum, palladium, rhodium, manganese, copper, etc. Has adopted a method of removing volatile organic compounds (VOC) using a catalyst cartridge type coated.

In such deodorization technology, the method of exhausting the odorous substances through the sewer pipe has a limitation of installation, and there is a problem in that the high temperature drying method has a limitation of removing the odorous substances.

The present invention has been made to solve the above problems, and provides a deodorization device of a food processor equipped with a high temperature catalyst treatment device and a low temperature catalyst treatment device at the same time, and by installing the low temperature catalyst treatment device outside the main body, It is to use as.

Deodorization apparatus of the food processor according to the present invention for achieving the above object is installed inside the outer case of the food processor, the first deodorizing unit for deodorizing the odor gas generated during the food processing process at high temperature; A cooling tube cooling the hot gas passing through the first deodorizing unit; And a second deodorization unit installed outside the case of the food processor to deodorize the gas cooled by the cooling unit again at a low temperature. And a control unit.

The cooling tube preferably has a spiral shape having a plurality of turns. In addition, the cooling tube is preferably formed of a good conductor such as silver or copper.

Here, it is preferable that a 1st deodorizing unit uses a high temperature catalyst cartridge.

In addition, the high temperature catalyst cartridge is preferably any one of platinum, palladium, rhodium, manganese, copper, zinc as a catalyst.

The second deodorizing unit is preferably a low temperature catalyst cartridge or an adsorption reactor filled with an adsorbent.

In addition, the low temperature catalyst cartridge may use a catalyst coated pellet or granular type activated carbon.

According to the present invention configured as described above, by having a first deodorizing unit operating at a high temperature and a second deodorizing unit operating at a low temperature at the same time, it is possible to efficiently install a deodorizing device in a narrow space, the effect of increasing the deodorizing efficiency of food There is.

These and other objects, features and other advantages of the present invention will become more apparent by describing in detail preferred embodiments of the present invention with reference to the accompanying drawings. Hereinafter, with reference to the accompanying drawings it will be described in detail the deodorizing device of the food processor according to an embodiment of the present invention.

1 is a schematic diagram showing a deodorizing device of a food waste processor in which the first and second deodorizing units 20 and 40 are installed.

First, as shown in FIG. 1, the food processor of the present invention deodorizes the gas at a high temperature with a grinder 60 that breaks down the food introduced into the food inlet 10 and the food inlet 10, which is a passage through which food is introduced. The second deodorizing unit 20 which deodorizes the cooled gas while passing through the cooling tube 30 and the cooling tube 30 that cools the high temperature gas deodorized by the first deodorizing unit 20 and the first deodorizing unit 20. 40 and the outlet 50 for discharging the deodorized food to the outside.

The food inlet 10 is preferably installed in the shape of a funnel or cylinder so that food waste can be well put. In addition, it is preferable to install a detachable device such as a funnel-shaped or cylindrical device in order to facilitate the cleaning of the food inlet.

When the food is introduced into the food inlet 10, it is difficult to deodorize when the food is put intact is provided with a crusher 60 to finely cut the food.

The gas generated from the crushed food is introduced into the first deodorization unit 20 through the first inlet 24.

The first deodorizing unit 20 is finely divided by the crusher 60 to deodorize the gas generated from the injected food in a high temperature state.

That is, as shown in Fig. 2, the gas generated in the food is heated using a heater 27 that generates a high temperature by power supply, and the gas is deodorized using the first cartridge unit 21. It is common to use high temperature catalyst cartridges.

The high temperature catalyst cartridge removes volatile organic compounds (VOCs) using catalysts such as platinum, palladium, rhodium, manganese, copper and zinc.

In the first deodorizing unit 20, deodorizing using a catalyst after drying at high temperature can deodorize basic and acidic gases such as ammonia, hydrogen sulfide, and methyl mercaptan.

The first heat insulating part 23 is installed outside the first deodorizing unit 20 to prevent high temperature heat from being released to the outside. This increases thermal efficiency and prevents the device from being easily damaged.

The first deodorizing unit 20 is provided with a first housing 22 on the outside. This absorbs external shocks and prevents thermal deformation of the first cartridge portion 21. In addition, the first deodorizing unit 20 may have a cylindrical shape or a rectangular parallelepiped shape.

A blower 70 is installed at the inlet of the first deodorizing unit 20 to facilitate the movement of substances such as gas generated by combustion.

The hot gas coming out of the outlet 25 of the first deodorizing unit 20 is introduced into the cooling tube 30.

Referring to FIG. 3, which shows the cooling tube 30 of FIG. 1, the cooling tube 30 cools the hot gas passed through the first deodorizing unit 20. The longer the cooling tube 30 is, the longer the movement time of the gas is, and thus the greater the cooling effect. Therefore, in order to form the cooling pipe 30 of the maximum length in a small space, a spiral passage having a plurality of turns is preferable.

The cooling tube 30 preferably uses a metal having high thermal conductivity for rapid heat transfer of the gas. For example, it is preferable to use a metal (conductor) such as silver or copper.

In order to increase the cooling effect of the gas passing through the first deodorizing unit 20, a separate cooling device may be installed around the cooling tube 30. However, in this case, there is a disadvantage that a space occupied by the cooling device is required.

The gas passing through the cooling pipe 30 is introduced into the second deodorizing unit 40 through the second inlet 44.

The second deodorization unit 40 is a device that deodorizes the gas passing through the cooling pipe 30 again at a low temperature.

In the second deodorizing unit 40, the deodorizing unit 40 is deodorized while passing through the second cartridge unit 41.

The second deodorizing unit 40 is provided with a second housing 42 on the outside. This serves to absorb external shocks. In addition, the second deodorizing unit 40 may have a cylindrical shape or a rectangular parallelepiped shape.

It is common for the second deodorizing unit 40 to use a low temperature catalyst cartridge. Alternatively, an adsorption reactor filled with an adsorbent may be used.

The cartridge of the second deodorizing unit 40 uses activated carbon of catalyst coated pellet or granule type. The malodorous gas removable in the second deodorizing unit 40 is gases such as trimethyl amine, acetaldehyde, methyl sulfide and the like.

Gas that is not removed from the first deodorization unit (high temperature catalyst deodorizer) 20 may be removed by a physical and chemical method in the second deodorization unit (low temperature catalyst deodorizer) 40. That is, when the low temperature catalyst cartridge is used in the second deodorization unit 40, the odor gas will be removed by a chemical method using a catalyst, and when the adsorption reactor is used in the second deodorization unit 40, the adsorption of the reactant material is performed. Odor gas will be removed by physical means.

The second deodorizing unit 40 is preferably installed outside the food processor. This is because, when installed outside the food processor, the cooling effect of the food is large and the disposal of the discharged food is easy. In addition, since the space occupies less, the space can be used efficiently.

Food passing through the second deodorizing unit 40 is discharged to the outside through the discharge port (50). Discharge port 50 is like a food inlet 10, it is preferable that a funnel-shaped or cylindrical device is installed. This is to facilitate the disposal of food waste. In addition, it is preferable that the funnel-shaped or cylindrical device is detachably installed so that the outlet can be easily cleaned.

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.
