Description

TECHNICAL FIELD [0001] The present invention relates to a deodorizing method and an apparatus for deodorizing food waste,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorization apparatus and a deodorization method for a food waste treatment apparatus, and more particularly, to a deodorization apparatus and a deodorization method for a food waste treatment apparatus for efficiently removing odorous gas.

Generally, a certain amount of food waste is discharged daily from each home or restaurant, and such food waste is used as livestock feed or filtered through a simple sieve filter to remove only the mixed water. This method of treating garbage increases the amount of garbage, and if the garbage is not frequently discarded, odor is generated to pollute the surrounding air. Thus, the use of the food waste disposer is increasing in general households and restaurants.

Although efforts to reduce food waste in general homes and restaurants have been promoted, there are various difficulties in controlling the amount of garbage that is gradually increasing. When landfill is made, the landfill site is limited, and odor and leachate The environmental damage caused by the earthquake was very serious.

So, recently, we have been implementing the trash weighting system, and the government has also stipulated that the processing equipment that can induce the fermentation, drying, or extinction of foodstuffs is obligatory to be installed when building new foodservice centers or apartment complexes .

However, the food waste contains about 80 ~ 90% of water. In order to reduce the amount of food waste, it is necessary to treat it by drying, fermentation process by heating, microbial reaction, etc. In this process, a large amount of water and high odor It was another treatment to solve this problem.

Especially, there is a problem of malodorous gas. Generally, malodorous components generated in the food processor are generated in various kinds of gases, and the composition of the gas varies depending on the type of food, the period of stay, When fermentation, that is, anaerobic fermentation occurs, it releases a large quantity of noxious odorous gas which can harm human body.

This is because, as the anaerobic conditions are formed partly during the continuous treatment of food waste, the more bad odor is generated, and the gas providing the cause of odor generated at this time can be separated into acidic, neutral and basic. Examples of the acidic gas include mercaptans such as hydrogen sulfide and methylmercaptan. Examples of the basic gas include amines such as ammonia and trimethylamine. Examples of the neutral gas include sulfides such as methyl sulfide and methyl disulfide, aldehydes such as acetaldehyde . These odorous gases are harmful to the human body, cause air and environmental pollution, and give a disgust to nearby facilities, which is serious.

In order to remove such odor gas, a food processor is provided with a deodorizing filter for removing odors of foods.

1 is a schematic diagram of a food processor according to the prior art.

1, the food waste disposal apparatus according to the related art includes a main body 1 in which food waste is crushed and dried, a deodorization filter 2 for purifying odor gas generated inside the main body 1, a deodorization filter 2, And a gas discharge pipe 3 through which the purified gas is discharged.

When the food waste is put into the main body 1, malodorous gas is generated in the process of pulverizing and drying the food in the main body 1. Such gas is generally discharged to the outside through the gas discharge pipe 3. In this case, a deodorizing device is used in order to purify environmental pollution and harm to the human body. In general, one deodorizing filter 2 is used.

The malodor gas generated in the main body 1 of the food processor is transferred to the deodorization filter 2 and the malodor gas introduced into the deodorization filter 2 is discharged to the outside through the gas discharge pipe 3 .

A conventional deodorization device for a food and beverage processing system generally uses a high-temperature catalyst system using an adsorption deodorization filter using activated carbon or a metal catalyst.

However, in the conventional deodorization apparatus of the above-mentioned conventional food processing apparatus, when the adsorption type deodorization filter is used, activated carbon is applied and its performance is maintained at a low temperature, but its use is limited at a high temperature. In general, it is important that the food processor operates at high temperatures in order to shorten the treatment time. Therefore, in the main body 1, odorous gas of high temperature is generated. Such a high-temperature gas reduces the performance of the activated carbon to reduce the durability of the adsorptive deodorization filter. On the other hand, the catalytic deodorizing filter has a high efficiency of use at a high temperature, but its efficiency is better at low temperatures.

SUMMARY OF THE INVENTION The present invention provides a deodorization apparatus and a deodorization method for a food waste treatment apparatus including an adsorption type deodorization filter and a catalytic type deodorization filter so that different types of deodorization filters can be used depending on the temperature of the exhaust gas .

And a gas circulation pipe connected between the second deodorization filter and the first deodorization filter and allowing the purified gas from the second deodorization filter to flow into the first deodorization filter.

According to another aspect of the present invention, there is provided a method for deodorizing a food processor, the method comprising: detecting a temperature of a malodorous gas generated when food is dried in a main body; If the temperature of the malodor gas is lower than the set temperature, And deodorizing the odor gas by a high temperature catalytic method when the temperature of the odor gas is equal to or higher than a set temperature.

According to the deodorization device and the deodorization method of the food waste disposer according to the present invention as described above, the deodorization filter and the deodorization filter are included, and when the odor gas is low temperature, it passes through the adsorption deodorization filter. The deodorization efficiency is increased and the overload of the deodorization filter is prevented, so that the durability of the deodorization filter is maintained.

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, a deodorizer and a deodorization method of a food processor according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram of a food processor according to an embodiment of the present invention.

1, a deodorization apparatus for a food waste disposal apparatus according to an embodiment of the present invention includes a main body 10 for drying food waste, a gas inflow pipe 20 for flowing odor gas generated from the main body 10, A temperature sensor 30 for detecting the temperature of the odor gas, a valve 40 for selectively opening and closing the flow path in accordance with the temperature of the gas detected by the temperature sensor 30, a low temperature gas pipe 50a for flowing low- A first deodorization filter 60a for purifying odor gas at a low temperature by an adsorption method, a second deodorization filter 60b for purifying odor gas at a high temperature by a catalytic method, And a gas discharge pipe 70 through which the purified gas passes through the first deodorizing filter 60a which is an adsorption type or the second deodorization filter 60b which is a catalytic type and is discharged to the outside.

The main body 10 may have a cylindrical or polyhedral container shape. A food inlet (not shown) is formed on the upper surface of the main body 10 so that food waste can be introduced. Since the main body 10 is directly exposed to the applied heat when the moisture is removed by applying heat to the food waste, the lower surface or the side surface of the main body 10 is made of a heat resistant material having a certain thickness capable of withstanding high temperatures, for example, a thermosetting resin It is good to lose. A heater (not shown) may be installed on the inner lower surface of the main body 10. As the heater, a heater using electric or gas may be used. The lower surface of the main body 10 is heated by the operation of the heater so that heat is transferred to the food waste disposed inside the main body 10. [ A temperature sensor (not shown) may be provided on the inner surface of the main body 10 and a liquid crystal display (not shown) may be provided on the outer surface of the main body 10 so that the temperature measured by the temperature sensor may be displayed The user can confirm the internal temperature of the main body through the liquid crystal display part in real time. The main body 10 may further include a control unit (not shown) connected to the temperature sensor or the heater to control the temperature inside the main body 10. In this case, the user may set a desired temperature through the control unit It is preferable that an operation unit is further provided on the outer surface of the main body 10.

When the food waste is introduced through the food inlet of the main body 10 and the food processor is operated, odorous gas is generated in the process of drying the food waste inside the main body 10. Such gas is generally discharged to the outside through the gas discharging portion of the food processor. In this case, a deodorizing filter is used in order to purify environmental pollution and harm the human body.

One end of the gas inlet pipe 20 is connected to the main body 10 so that the malodor gas generated from the main body 10 flows.

The temperature sensor 30 is provided on the flow path of the gas inlet pipe 20 to detect the temperature of the malodorous gas. Here, the detected temperature value is sent to a control unit (not shown), and the control unit determines whether the detected value is higher or lower than the set value, and actuates the valve 40.

The valve 40 is provided at the other end of the gas inflow pipe 20 to selectively open and close the flow path according to the gas temperature detected by the temperature sensor 30. [ At this time, the set temperature value is 60 ~ 80 ℃. And most preferably 70 ° C.

That is, if the detected temperature value of the malodorous gas is equal to or lower than the set value 70 deg. C, the valve 40 opens the low temperature gas pipe 50a and closes the hot gas pipe 50b. Conversely, when the detected temperature value of the malodor gas exceeds 70 deg. C, which is the set value, the valve 40 closes the low temperature gas pipe 50a and opens the hot gas pipe 50b.

The low temperature gas pipe 50a connects the valve 40 and the adsorption deodorization filter 60a, and low temperature odor gas flows.

The hot gas pipe 50b connects the valve 40 and the catalytic deodorization filter 60b, and hot odor gas flows.

The adsorption deodorization filter 60a is provided at the other end of the low temperature gas pipe 50a to purify odor gas at a low temperature, and activated carbon is applied. Alternatively, the adsorption deodorization filter 60a may be composed of a dual filter made of activated carbon and alumina.

Although the durability of the activated carbon drastically decreases at high temperatures, the adsorption deodorization filter 60a of the present invention only passes low-temperature odor gas, and thus its performance is maintained.

The catalytic deodorization filter 60b is provided at the other end of the hot gas pipe 50b to purify hot odor gas, and a high temperature catalyst is applied. Since the catalytic deodorization filter 60b is poisoned by sulfur compounds, its durability is drastically reduced. However, since the catalytic deodorization filter 60b of the present invention is used only when the odor gas is at a high temperature, the filter is prevented from being overloaded and durability is maintained .

In addition, since the catalytic deodorization filter 60b needs to heat the catalyst at 250 ° C or higher, electricity is used in many cases. If the catalytic deodorization filter 60b and the adsorption deodorization filter 60a are selectively used, the electricity cost is reduced .

The gas discharge pipe 70 connects the adsorption deodorization filter 60a and the catalytic deodorization filter 60b to the outside and flows through the adsorption deodorization filter 60a or the catalytic deodorization filter 60b to purify the gas And is discharged to the outside.

Hereinafter, a method for deodorizing a food processor according to an embodiment of the present invention will be described.

The food waste introduced through the food intake port is crushed and dried in the main body 10.

During the pulverization and drying process of the food garbage, a high-temperature odor gas is generated, and the gas flows into the gas inlet pipe 20 and flows. The temperature sensor 30 provided in the gas inlet pipe 20 detects the temperature of the odor gas flowing in the gas inlet pipe 20, and the detected temperature value is sent to the control unit (not shown). The control unit compares the detected value with the set value to actuate the valve 40. [ At this time, if the detected temperature value of the odor gas is lower than the set value, the valve 40 opens the low temperature gas pipe 50a and closes the hot gas pipe 50b. Conversely, when the detected temperature value of the malodor gas exceeds the set value, the valve 40 closes the low temperature gas pipe 50a and opens the hot gas pipe 50b. The odor gas flowing through the low temperature gas pipe 50a or the hot gas pipe 50b is purified while being passed through the adsorption deodorization filter 60a or the catalytic deodorization filter 60b and is discharged to the outside through the gas discharge pipe 70. [

At this time, since the low-temperature adsorption deodorization filter 60a passes through the low-temperature adsorption deodorization filter 60a, its performance is maintained, and the catalytic deodorization filter 60b is used only when the odorous gas is high temperature, / RTI >

A gas inlet pipe 20, a temperature sensor 30, a valve 40, a low temperature gas pipe 50a, a hot gas pipe 50b, an adsorption deodorization filter 60a, and a catalytic deodorization filter 60b. Is the same as the embodiment of the present invention.

The gas circulation pipe 50c connects the catalytic deodorization filter 60b and the adsorption deodorization filter 60a so that the purified gas from the catalytic deodorization filter 60b flows into the adsorption deodorization filter 60a.

Here, the hot odor gas passes through the catalytic deodorization filter 60b and flows through the gas circulation pipe 50c, thereby lowering the temperature. The malodorous gas whose temperature is lowered is introduced into the adsorption deodorization filter 60a and purified secondarily, thereby improving the purification efficiency.

The gas discharge pipe 70 connects the adsorption deodorization filter 60a with the outside, and the purified gas passes through the adsorption type deodorization filter 60a and is discharged to the outside.

Hereinafter, a method for deodorizing a food processor according to another embodiment of the present invention will be described.

The food waste introduced through the food intake port is crushed and dried in the main body 10.

During the pulverization and drying process of the food garbage, a high-temperature odor gas is generated, and the gas flows into the gas inlet pipe 20 and flows. The temperature sensor 30 provided in the gas inlet pipe 20 detects the temperature of the odor gas flowing in the gas inlet pipe 20, and the detected temperature value is sent to the control unit (not shown). The control unit compares the detected value with the set value to actuate the valve 40. [ At this time, if the detected temperature value of the odor gas is lower than the set value, the valve 40 opens the low temperature gas pipe 50a and closes the hot gas pipe 50b. Conversely, when the detected temperature value of the malodor gas exceeds the set value, the valve 40 closes the low temperature gas pipe 50a and opens the hot gas pipe 50b. The low-temperature odor gas flowing through the low temperature gas pipe (50a) is purified while being passed through the adsorption type deodorization filter (60a) and discharged to the outside through the gas discharge pipe (70). On the other hand, the hot odor gas flowing through the valve 40 and flowing through the hot gas pipe 50b is purified while passing through the catalytic deodorization filter 60b and flows through the gas circulation pipe 50c, And then flows into the deodorization filter 60a. The lowered temperature of the malodor gas is secondarily purified while passing through the adsorption deodorization filter 60a and discharged to the outside through the gas discharge pipe 70.

At this time, since the low-temperature adsorption deodorization filter 60a passes through the low-temperature adsorption deodorization filter 60a, its performance is maintained and the catalytic deodorization filter 60b is used only when the odor gas is high temperature. And the deodorization efficiency is increased.

In addition, the high-temperature odor gas generated in the main body 10 is purified through the adsorption deodorization filter 60a and the catalytic deodorization filter 60b, thereby improving the purification efficiency.
