Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

More particularly, the present invention relates to an indirect heating type food processor which is easy to install, has a space efficiency, and is equipped with a dehumidifying device in the lid part to effectively remove moisture present in the air inside the device .

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 in general households and restaurants. However, it is difficult to control the amount of waste increasing gradually. When the landfill is limited, the landfill site is limited. Environmental damage has become 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 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 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 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, and cause air and environmental pollution.

Food waste containing a lot of water is easily decayed, and it is easy to decay. It is harmful to the surrounding hygiene environment by emitting bad smell. Many companies have tried to develop the technology, and they have been making hot air circulation for food and household waste disposal Method, the hot air circulation drying method with the stirring function, the hot air circulation drying method with the stirring function and the crushing function, the method using the stirring function and the microorganism simultaneously, and the refrigeration storage method, Has been released.

However, this type of food processor has a problem in that it can not effectively remove moisture generated during the operation.

1 to 3, an indirectly heated food processor 100 according to an embodiment of the present invention includes a cylindrical container-shaped main body 110 having a heating device 140 installed on an inner lower surface thereof to heat the introduced food, An intake part 124 which is detachably installed on the upper part of the main body part 110 and through which air flows from the outside and an exhaust part 128 through which the air inside the main body part 110 is discharged to the outside, A dehumidifying device 160 having a beam structure provided along the circumference on the inner bottom surface of the lid 120, a water purifying device 160 installed inside the main body 110 to receive food, A heat transfer unit 130 provided between the main body 110 and the inner drying compartment 130 for transferring heat generated in the heating device 140 to the inner drying compartment 140, 150).

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

A heating device 140 may be installed on the inner lower surface of the main body 110. As the heating device 140, a heater using electricity or gas may be used. Due to the operation of the heating device 140, the lower surface of the main body 110 is heated and heat can be transferred to other containers or materials provided inside the main body 110.

The air heated from the lower surface inside the main body 110 is moved to the upper portion of the main body 110 by the air convection principle that the warm air rises up.

The heating device 140 may be provided on the side surface of the main body 110 or may be formed to extend along the shape of the main body 110. A temperature sensor 115 is provided on the inner surface of the main body 110 and a liquid crystal display part 118 is provided on the outer surface of the main body 110 so that the temperature measured by the temperature sensor 115 can be displayed . The user can confirm the internal temperature of the main body 110 in real time through the liquid crystal display unit 118.

A control unit (not shown) for controlling the temperature inside the body 110 connected to the temperature sensor 115 or the heating unit 140 may be further provided. Of course, in this case, an operation unit may be further provided on the outer surface of the main body 110 so that the user can set a desired temperature through a control unit (not shown).

The lid part 120 is provided on the upper part of the main body part 110 and includes an intake part 124 and an exhaust part 128 so that air can flow between the inside and the outside of the main body part 110.

The intake part 124 is connected to the intake hole 121 so that the air introduced into the intake hole 121 formed in the outer upper surface of the lid part 120 is moved into the body part 110. [ And an intake fan 123 provided in a passage of the intake pipe 122. [ The intake unit 124 may be provided at the center of the lid unit 120 to uniformly supply the air sucked from the outside to the main body unit 110. [

The intake holes 121 may be enough to allow the air to sufficiently pass therethrough, so that it may be one large hole or a plurality of small holes. The intake pipe 122 serves as an air flow path. The intake fan 123 is a device for sucking air from the outside into the interior of the main body 110. The air introduced into the main body 110 by the intake fan 123 is guided to the lower side of the main body 110 . At this time, since the lower surface of the main body 110 is heated by the heating device 140, the introduced air receives heat and moves toward the upper portion of the main body 110 again. The intake fan 123 is preferably made of a wear-resistant material because it contacts the air at a high flow rate.

The exhaust unit 128 discharges the air introduced into the hollow cylindrical lid 120 through the plurality of air outlets 125 and the air outlets 125 provided on the inner bottom surface of the lid 120, An exhaust hole 126 provided at one side of the lid 120 and an exhaust pipe 127 connected to the exhaust filter 126 at one side and an external filter at the other side. Also, a dehumidifier 160 having a beam structure is provided along the circumference on the inner bottom surface of the lid 120.

The air that has flowed from the main body 110 to the inside of the lid 120 through the air outlet 125 contains a large amount of water. Therefore, water can condense on the top surface of the inside of the lid to form water droplets, and moisture can also condense on the bottom surface of the lid. If the moisture is not removed, the inside of the lid 120 may be corroded, and bacteria or fungi may be generated, resulting in a hygiene problem.

In order to solve the above problems, a dehumidifier 160 having a beam structure may be provided on the inner bottom surface of the lid 120. As the beam structure, an 'H' beam, a 'C' beam, or the like can be used. This is for the purpose of collecting moisture on one side of the dehumidifier 160. The user can remove the moisture existing in the dehumidifier 160 by removing the cover 120 and removing the dehumidifier 160 having a beam structure provided along the circumference of the circumference.

The central portion of the inner upper surface or the inner lower surface of the cylindrical lid 120 may be slightly raised to be inclined as a whole in order to facilitate removal of moisture.

The inner drying compartment 130 shown in FIGS. 1 to 3 is installed inside the main body 110 and serves to receive food waste. The food waste heated by the heating device 140 provided on the inner lower surface of the main body 110 can be attached to the inner surface of the main body 110 when the food waste is stored in the main body 110 directly, The inner surface of the main body 110 may be easily damaged. Therefore, an inner drying compartment 130 is used, which can treat food waste separately. The inner drying chamber 130 may be in the form of a polyhedron or a cylindrical container like the main body 110.

The inner drying chamber 130 may be formed of aluminum having high thermal conductivity, or may be formed of another metal having a good thermal conductivity. In addition, a Teflon coating may be applied to protect the surface of the inner drying chamber 130 and to prevent the food from being pressed.

The heat transfer unit 150 is installed between the main body 110 and the inner drying compartment 130 to heat the heat generated from the heating device 140 installed on the inner lower surface of the main body 110, . The shape of the heat transfer part 150 varies depending on the shape of the inner drying compartment 130, and is generally a plate shape made of copper, silver or aluminum. Both copper, silver and aluminum have good thermal conductivity, but there is a difference in price.

The heat transfer portion 150 may be a complete plate shape or a plate-like shape having a hole formed therein. When a component other than the heat transfer unit 150 is added between the main body 110 and the inner drying compartment 130, a plate having a hole formed therein may be used.

The main body 110 and the lid 120 may be made of a heat-resistant material such as a thermosetting resin. It must be made of a material that is not easily deformed since it is supplied with the continuous heat by the heating device 140.

The operation of the indirect heat type food and beverage processing apparatus 100 according to the present invention will be described with reference to FIG. The user opens the cover 120 and puts the food waste in the inner drying compartment 130 provided inside the body 110 to operate the indirect heating type food processor 100. The heating device 140 is operated to heat the main body 110 and the inner drying compartment 130 so that heat is transferred to the food waste accumulated in the inner drying compartment 130 to evaporate moisture.

When the inside of the main body 110 is heated to a certain extent, the intake fan 123 operates and external air flows into the main body 110 through the intake hole 121 and the intake pipe 122. And the flow path of air introduced into the main body 110 is denoted by "A ". Various harmful gases and odors generated when the food processor stacked in the inner drying compartment 130 is dried are mixed with the air introduced through the intake part 124, and the temperature of the inflow air is increased.

The warm air moves upward, so that the air containing various gases and odors moves toward the lid 120. The raised air moves through the air outlet 125 provided in the inner lower surface of the lid 120 to the inside of the lid 120. Air containing a noxious gas whose moisture has been removed from the lid part 120 by a predetermined amount flows through an exhaust pipe 127 provided in an exhaust hole 126 of the lid part 120 and flows through the first deodorization filter and the second deodorization filter And then discharged to the outside.

Since the air inside the main body 110 of the indirect heating type food processor 100 contains various kinds of harmful gas and odor, if it is discharged into the air as it is, there is a fear of harming environment pollution and user's health. Therefore, the process of cleansing it is essential. In particular, acidic gases such as hydrogen sulfide and basic gases such as ammonia can have a fatal effect on the human body.

Therefore, the primary deodorizing filter and the secondary deodorizing filter are provided so as to remove the harmful gas and odor of the discharged air, and pass through it.

In the deodorization method, an activated carbon adsorption method, a chemical liquid washing method, a microorganism deodorization method, an ozone oxidation method, or the like can be used, and in particular, a deodorization method using a catalyst is widely used.

The primary deodorization filter and the secondary deodorization filter are designed to remove the different types of noxious gases by differentiating the components involved and the catalyst used. The first deodorization filter and the second deodorization filter are added with a catalyst for increasing deodorization efficiency at high temperature and a catalyst for increasing deodorization efficiency at low temperature. Catalysts with high deodorization efficiency at high temperatures usually include platinum, palladium, rhodium, manganese, copper, and volatile organic compounds (VOCs).

The air that has passed through the primary deodorization filter and the secondary deodorization filter is removed from harmful gases and odors and released into the atmosphere.

Although the preferred embodiments of the present invention have been described, the present invention is not limited to the specific embodiments described above. It will be apparent to those skilled in the art that numerous modifications and variations can be made in the present invention without departing from the spirit or scope of the appended claims. And equivalents should also be considered to be within the scope of the present invention.
