Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an internal circulation type food waste disposal apparatus having a dehumidifying device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food processor for drying food waste, and more particularly, to an internal circulation food processor having a dehumidifier for easily removing moisture in a food processor.

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.

Recently, efforts to reduce food waste in general homes and restaurants have been actively promoted, but there are various difficulties in controlling the amount of garbage that is increasingly increasing. Landfill sites are limited when food waste is landfilled, and environmental damage due to odor and leachate 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, cause air and environmental pollution, and give a disgust to nearby facilities.

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.

1 is a block diagram of a conventional food processor. As shown in FIG. 1, the food processor includes a food processor main body 100 for crushing and drying the food waste introduced through the food inlet 105, a deodorizer for purifying harmful gas generated in the food processor main body 100, And a filter unit 120. The deodorization filter unit 120 receives a noxious gas generated in the main body part 100 of the food processor through an inlet 131 connected to the gas flow pipe 115, A purified air discharge port 170 for discharging the purified gas from the filter unit 130 to the outside through a connection pipe 150 provided in the discharge port 133, and the like. In general, the filter unit 130 uses a catalyst filter or an AC filter (activated carbon), and the filter unit 130 may be surrounded by the heat insulating unit 160.

Such conventional food waste disposer does not effectively remove water generated in the food waste disposal apparatus, so that food waste is easily corroded and deteriorated in hygiene, and the apparatus is corroded. In addition, there is a problem that the deodorization efficiency is deteriorated because the gas containing a large amount of moisture generated in the main body of the food processor moves directly to the deodorizing filter portion.

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. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an internal circulation type food and beverage processing apparatus having a dehumidifier according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of an internal circulation type food and beverage processing apparatus provided with a dehumidification device according to an embodiment of the present invention.

Referring to FIG. 2, the food processor according to an embodiment of the present invention includes a food processor main body 200 for crushing and drying the food waste introduced through the food inlet 205, a food processor main body 200, A dehumidifier 280 connected to the flow path 215 and configured to receive gas discharged from the food processor main body 200 to remove water from the gas, a dehumidifier 280 connected to the dehumidifier 280, And a deodorization filter unit 220 for purifying the dehumidified gas.

 The deodorization filter unit 220 includes an AC filter unit 230 for primarily receiving the dehumidified gas from the dehumidifier 280 through the second gas flow pipe 218, And a purified air outlet 270 for exhausting the purified gas from the catalyst filter 240 to the outside. Of course, the AC filter unit 230 and the catalytic filter unit 240 may be changed in position, and only one type of filter may be used, either the AC filter unit 230 or the catalytic filter unit 240.

The food inlet (205) is preferably provided with a funnel-shaped or cylindrical device to accommodate food waste. 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.

Since the foodstuff injected into the food intake port 205 may be difficult to be deodorized, a disintegrator may be further provided in the main body 200 of the foodstuff processing machine so that the foodstuff can be finely cut.

A feed pulverizing member (not shown) may be provided in the main body 200 of the food processor 200 so as to pulverize the charged food waste, and a drying oven (not shown) may be provided to dry the pulverized food waste have. As the conveying pulverizing member (not shown), a pulverizing blade in the form of a screw is used, though it differs depending on the use. Also, although the drying furnace is different depending on the drying method, it is provided with a drying furnace and a heat supply device of a predetermined size.

During grinding and drying treatment of food waste, a large amount of odor and moisture containing gas are generated. Also, since this gas is heated to be dried, it is at a high temperature of about 70 to 80 ° C.

Generally, after treating 1kg of food waste, only 200 ~ 300g will be left. At this time, the shrinking 700 ~ 800g is mostly water and odor gas. The amount of water (water vapor) is relatively higher than that of the odor component.

The dehumidifier 280 is a water separator that removes moisture of the gas generated in the main body 200 of the food processing unit 200 by using a centrifugal force and a collision action or a water separator of the gas generated in the main body 200 of the food processor 200 Which may be a water trap.

FIG. 3 is a perspective view of a water separator used in a food processor according to an embodiment of the present invention, and FIG. 4 is a configuration diagram of a water trap used in a food processor according to an embodiment of the present invention.

3, the water separator includes a first gas flow pipe 215 for receiving the gas generated in the main body 200 of the food processor, and a second gas flow pipe 218 for discharging the dehumidified gas in the water separator. A cylindrical body portion 290 provided at the lower end of the head portion 281 and hollowed inside to circulate the gas introduced from the first gas flow pipe 215, A hollow cylindrical separating tube 288 whose one end is fixed to the inner upper end of the head portion 281 and which is long in the downward direction, A swirl generator 287 fixed to one end of the rotary shaft 283 and rotated at the same time in accordance with the movement of the rotary shaft 283 at the upper end of the body 290, The body portion 290 The lower side is provided in include automatic baesujang value (289) for automatically discharging the water generated by the rotation of the vortex generator (287).

The automatic drainage device 289 may be in the form of a choke valve operated by a control part (not shown). In this case, if the water generated in the body portion 290 of the water separator is filled up to a certain amount, the water level can be measured by a sensor (not shown), and the control unit (not shown) can operate the choke valve.

The vortex generator 287 is connected to hollow cylinders of two different sizes and the upper cylinder 284 having a small diameter among the two cylinders is installed inside the separation tube 288 to rotate in contact with the separation tube 288 And a large diameter lower cylinder 285 is installed to rotate in the body portion 290 and a plurality of separation plates 286 are provided in the diagonal direction along the circumference of the lower end cylinder 285.

3, the operation of the water separator will be described. The gas of high temperature and high humidity generated in the body of the food processor 200 is introduced into the dehumidifier 280 through the first gas flow pipe 215, that is, inside of the water separator Lt; / RTI > The vortex generator 287 fixed to the lower ends of the rotary shaft 283 and the rotary shaft 283 is rotated by the operation of the motor 282 installed on the head portion 281 of the water separator, And the rotational force is transmitted to the lower air. The gas introduced through the first gas flow tube 215 is rotated along the space between the hollow cylindrical separating tube 288 provided inside the head portion 281 and the inner surface of the head portion 281. At this time, since a large amount of water is contained in the air colliding with the separation pipe 288, water will condense at the time of collision to form water droplets and fall downward.

The gas introduced into the water separator flows toward the vortex generator 287 by the rotation of the vortex generator 287. At this time, the gas will flow into the body portion 290 along the outer surface of the separation tube and vortex generator 287. In this case, since the plurality of separation plates 286 provided on the circumferential surface of the lower end cylinder of the vortex generator 287 are rotated at a high speed, water collides with the gas introduced into the water separator to form water droplets It will fall downward by gravity.

The water whose moisture has been removed by the rotation of the vortex generator 287 circulates in the water separator body portion 290 and flows into the second gas flow tube 218 through a hole formed at the center of the vortex generator 287.

Water generated inside the body portion 290 of the water separator will flow to the water reservoir 296 along the water flow tube 295 by operation of the automatic drain 289.

4, the water trap is provided with a water trap inner pipe 293 whose diameter and direction are rapidly changed. In the operation of the water trap, gas generated in the body of the food processor flows into the water trap through the first gas flow pipe 215 and passes through the water trap inner pipe 293. (A) the gas inlet is narrow, but the gas inlet is suddenly turned and bent (B). The water trap inner pipe 293 is repeatedly bent in the direction of expansion and contraction and in the diagonal direction so as to be formed as long as possible in a small space.

The gas flowing into the water trap changes in flow rate as the pipe shrinks and expands, and water collides with the suddenly bent portion (B) to form water droplets. The water generated inside the water trap inner pipe 293 flows downward along the water trap inner pipe 293 by gravity and is stored in the water storage tank 296 through the water flow pipe 295. The condensed water and gas are discharged through the water flow pipe, and the gas is discharged to the outside of the water trap through the second gas flow pipe by the suction force of the suction pump 292 provided at one side of the second gas flow pipe.

The moisture-removed gas passing through the dehumidifier 280 such as a water separator or a water trap flows to the deodorization filter unit 220 through the second gas flow pipe 218. The second gas flow pipe 218 is installed in the first inlet 231 provided in the upper part of the AC filter unit 230 in the deodorization filter unit 220. The gas passing through the second gas flow pipe 218 is supplied to the AC And then flows into the filter unit 230. The gas that has been primarily purified by the AC filter unit 230 flows to the catalytic filter unit 240 through the connection pipe 250 provided at the first outlet 233 at the lower end of the AC filter unit 230. The gas that has been re-circulated in the catalyst filter unit 240 flows to the purified air outlet 270 through the second outlet 243 provided on the catalyst filter unit 240 and is discharged to the outside. Of course, the AC filter unit 230 and the catalytic filter unit 240 may be changed in position, or only one type of filter may be used, such as the AC filter unit 230 or the catalytic filter unit 240.

The AC filter unit 230 and the catalyst filter unit 240 of the deodorization filter unit 220 are connected through a connection pipe 250 provided between the first outlet 233 and the second inlet 241.

Activated carbon is provided inside the AC filter unit 230. Activated carbon generally has a surface area of 700 to 17000 times that of pores.

The use of activated carbon has an advantage in that it has excellent ability to remove pesticides, synthetic detergents and odors. However, as the adsorption progresses, the efficiency decreases and exchange or regeneration is required, and if the air is backwashed, the impurities are discharged again.

The adsorption amount of the activated carbon filter is different when the concentration of the harmful gas is high or low, which can be adjusted by the pore size distribution of the activated carbon or the impregnated material.

A catalytic cartridge is provided in the catalyst filter unit 240. As the catalyst cartridge, a high-temperature catalyst cartridge or a low-temperature catalyst cartridge is generally used.

The high temperature catalyst cartridge may be prepared by removing a volatile organic compound (VOC) by using a catalyst such as platinum, palladium, rhodium, manganese, copper or zinc and the low temperature catalyst cartridge may be a catalytic coated pellet or granule type activated carbon Can be used to remove gases such as trimethylamine, acetaldehyde, and methyl sulfide.

The AC filter 230 and the catalytic filter 240 are installed outside the catalytic filter 240 to prevent the heat from being discharged to the outside. This is to increase the thermal efficiency and prevent the internal parts of the food processor from being easily damaged.

In the filter device provided in the conventional food processor, the odor gas is directly purified from the deodorizing filter. However, if a large amount of moisture is contained in the odor gas, the deodorizing efficiency of the deodorizing filter is decreased, the deodorizing filter can not be used for a long time, There was a problem.

However, according to the embodiment of the present invention, the dehumidification device 280 dehumidifies the deodorization filter unit 220 before the gas enters the deodorization filter unit 220, thereby deodorizing the dehumidified gas using the deodorization filter unit 260, So that the replacement cost can be reduced.

The purified and dehumidified gas that has passed through the deodorization filter unit 220 passes through the inner circulation pipe 275 and passes through the air inlet 212 provided at one side of the food processor main body 200, 200, and is used again in the process of heating or crushing the food waste put into the food inlet 205.

If new outside air is used in the body 200 of the food processor, energy is consumed to heat the food to a predetermined temperature. However, if the gas generated during the food processing process is dehumidified and purified, the internal circulation tube 275 The passing gas maintains a constant high temperature, so energy consumption can be reduced.

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 be regarded as falling within the scope of the present invention.
