Description

{Food waste disposal device}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food garbage disposer, and more particularly, to a food garbage disposer capable of maximizing weight loss efficiency by sequentially performing fermentation and drying of food garbage.

Generally, food wastes generated from homes and restaurants are mixed with various mixtures and contain a large amount of water. Therefore, not only is it easily decayed when the temperature is high, but when such food wastes are buried in the ground as they are, Leachate is generated together with serious environmental pollution that pollutes soil and groundwater.

When these food wastes are landfilled with waste, they cause waste of resources, as well as cost of waste disposal and environmental pollution, that is, leachate generated from food waste causes soil pollution and water pollution, Gas, and pests, causing various skin diseases and infectious diseases.

Recently, food waste has been appropriately treated by local governments, such as landfill and marine dumping, while incineration has been carried out for the use of one side cogeneration system or partly by processing with feed and fertilizer to be used as resources. However, due to environmental pollution problem, marine dumping is prohibited, And prohibition of feed processing due to the occurrence of diseases.

On the other hand, the food waste has a moisture content of 80% or more, which means that 80% of the amount of food waste can be reduced by simply removing water. In the case of Korean Patent Registration No. 10-0890206 (2009.04.03.) (Hereinafter referred to as "Prior Art 1") as a technology relating to a conventional food waste disposer, water is removed by heating at high temperature In addition, when the device is accompanied by fermentation by microorganisms, there is a problem that the microbial fermentation itself is adversely affected by high temperature heating, and when the fermentation by the odor and microorganisms of the food garbage itself occurs There is a problem in that a separate deodorizer must be installed in addition to the food waste disinfector in order to remove the odor of the food waste.

In order to solve this problem, Korean Patent No. 10-1238305 (hereinafter referred to as Prior Art 2) discloses a fermentation extinction unit for fermenting microorganisms while stirring food wastes and evaporating moisture by a heat source 10); An air supply unit 40 for supplying air to the fermentation destruction unit 10; An air circulation unit 20 for sucking and exhausting air in the fermentation destruction unit 10 and circulating the air in the fermentation destruction unit 10; And a dehumidifying part (30) for condensing and absorbing the air exhausted through the air circulating part (20) into water to remove the moisture, wherein the air in the fermentation destruction unit (10) 10, the air circulation unit 10 and the dehumidifying unit 30, and the fermentation destruction unit 10 is a tubular housing, and the heat source is provided on the outer surface of the tubular housing The oil jacket 14 is filled with oil as a heating medium and the oil is heated by a heater inserted in the oil jacket 14. The air circulating unit 20 is connected to a blower And the air supply unit 40 comprises a valve 41 provided in an air supply pipe 42 formed in a pipe between the fermentation destruction unit 10 and the blower 21, The water in the dehumidifying part 30 is supplied to the dehumidifying part 30 The refrigerant is cooled by a cooler 50 composed of a compressor 51 and a radiator 52. Microorganisms are introduced into the dehumidifying unit 30 to cool the dehumidifying unit 30, The air passing through the dehumidifying part 30 is circulated through the oil jacket 14 by using the copper pipe 15 provided on the outer surface of the oil jacket 14 as heat exchange means, And is circulated to the fermentation extinction unit 10. The fermentation extinction unit 10 is divided into at least two fermentation extinction units and the partition wall 16 for partitioning the fermentation extinction unit 10 When the fermentation extinction unit 10 is divided into at least three fermentation extinction units, the size of the holes of the perforated plate becomes smaller toward the fermentation extinction unit 10 at the subsequent stage, and the fermentation extinction unit 10 The installed stirrer 17 is provided with An air filter unit (70) for purifying the air passing through the dehumidifying unit (30) is provided between the dehumidifying unit (30) and the fermentation destruction unit (10) Further comprising a water filter unit (60) for purifying water overflowed from the dehumidifying unit (30).

In the case of the prior arts 1 and 2, since the moisture is removed by a dehumidifying method using a refrigerant, the energy efficiency is extremely low. Particularly, in the case of the prior patent 2, the applicant has developed it. There is a problem that the operation efficiency of the dehumidifying part in winter is lowered further.

On the other hand, since the conventional food processor performs only one of fermentation and drying, there is a problem that it takes much time for the food waste to disappear and the food waste to dry due to fermentation.

In addition, the terms described below are defined in consideration of the functions of the present invention, and these may vary depending on the intention of the user, the operator, or the precedent. Therefore, the definition should be based on the contents throughout this specification. In the description of the present invention, the same or similar reference numerals are given to the same or similar components, and a detailed description thereof will be omitted.

Referring to FIGS. 1 to 5, the food waste disposal apparatus 10 according to the present invention maximizes the reduction efficiency by sequentially performing fermentation and drying of food waste, and includes a housing 11 for accommodating food waste, A fermentation unit 12 provided at one side of the inside of the housing 11 for fermenting microbial fermented food wastes, and a microbial fermenter 12 provided at the other side of the inside of the housing 11 for receiving food wastes fermented by the fermentation unit 12 A heating unit for supplying heat to the drying unit 13 and an agitating unit 112 disposed transversely to the housing 11 for stirring and conveying food waste.

The housing 11 includes a fermentation section 12 and a drying section 13 and includes an agitating section 112 for passing foodstuff waste through the fermentation section 12 and the drying section 13, Respectively.

The distinction between the fermentation unit 12 and the drying unit 13 can be divided into whether the fermentation unit 12 and the drying unit 13 are fermented or not.

The fermentation unit 12 is different from the fermentation unit 12 in that microorganism fermentation is performed and no separate heating unit is installed, but the drying unit 13 is provided with heating means without microbial fermentation.

More specifically, the fermentation unit 12 includes a charging chamber 12a having a charging port 121 for charging food waste, and a fermentation chamber 12b for fermenting food waste supplied from the charging chamber 12a. do.

A display (not shown) for voice or visually guiding information such as the input port 121 provided at the upper end of the input chamber 12a or the weight of the charged food waste at a side of the input port may be provided. A wireless terminal (not shown) may be installed on the display to recognize a user by an RFID system.

The loading chamber 12a may be provided with a load cell (not shown) for measuring the weight of the charged food waste.

At least the fermentation chamber 12b of the charging chamber 12a and the fermentation chamber 12b is filled with microorganisms for fermenting the food waste.

The input chamber 12a and the fermentation chamber 12b are partitioned by a first partition wall 15a and a first transfer hole 16a through which the food waste passes is formed in the first partition wall 15a.

The stirring unit 112 includes a motor 115 installed at one side of the housing 11, a rotating shaft 113 connected to the motor and disposed horizontally, and a plurality of blades 114 installed at the outer circumferential surface of the rotating shaft As shown in FIG. 5, at least one pair of blades 115 facing each other is constituted by a pair of blades facing each other, so that the agitation of the food waste in one direction So that it is very uniformly performed without being hit or deflected. However, since the first feed hole 16a is formed in the lower portion of the first partition wall 15a, the food waste contained in the feed chamber 12a is agitated, and is sucked into the fermentation chamber through the first feed hole 16a Out.

Similarly, between the fermentation chamber 12b and the first drying chamber 13a and between the first drying chamber 13a and the second drying chamber 13b are divided into second and third partition walls 15b and 15c, And is conveyed through the second and third transfer holes 16b and 16c.

The transfer holes provided in the plurality of partition walls partitioning the respective chambers can be arranged at different heights. For example, the transfer holes formed in the first partition wall 15a partitioning the input chamber 12a and the fermentation chamber 12b 1 transfer hole 16a may be disposed lower than the second transfer hole 16b formed in the second partition wall 15b and the third transfer hole 16c formed in the third partition wall 15c have.

More specifically, since the weight of the charged food wastes is checked in the feeding chamber 12a and temporarily stored and then supplied to the fermentation chamber 12b, the height of the first feeding hole 16a is shifted to the second, The reason why the second and third transfer holes 16b and 16c are arranged at a higher level is that the retention times in the fermentation chamber 12b and the first and second drying chambers 13a and 13b are set lower than the holes 16b and 16c, In order to secure sufficient space. The second and third transfer holes 16b and 16c can be formed at a height of about 60 to 80 cm when the height of the second and third partition walls 15b and 15c is 100 cm.

A first nozzle 122 may be formed at one side of the charging port 121 to spray a malodor removing mist in order to remove odors generated when the charging port 121 is opened.

The malodor removing mist can be exemplified by water and microorganisms.

In the fermentation chamber 12b, a second nozzle 123 for supplying fermentation microorganisms to the food waste may be formed.

The microorganisms supplied from the first and second nozzles 122 and 123 are not particularly limited as long as they are capable of decomposing malodorous components or fermenting, decomposing, or destroying food waste, and may be selected from known microorganisms used in the field of food waste disposal .

The first and second nozzles 122 and 123 may be provided with a solenoid valve so that the malodor removing mist or the fermenting microorganism may be injected periodically every time the inlet is opened or at predetermined time intervals.

The batch chamber 12a, the fermentation chamber 12b, the first drying chamber 13a, and the second drying chamber 13b are sequentially disposed, and the volume of each chamber is gradually reduced and dried as the process progresses. The first drying chamber 13a and the second drying chamber 13b may be formed in such a manner that the space between the input chamber 12a, the fermentation chamber 12b, the first drying chamber 13a, and the second drying chamber 13b is reduced, As a result of the experiment, it is preferable to have a volume ratio of 4: 2.8 to 3.2: 1.8 to 2.2: 0.8 to 1.2.

The heating means may be a thermal jacket 17 surrounding the lower outer surfaces of the first drying chamber 13a and the second drying chamber 13b and circulating the heated fluid (oil, water) through the inside thereof.

Moisture generated in the food waste heated by the thermal jacket 17 is discharged through the suction line 151 installed in the upper portion of the first drying chamber 13a and / or the second drying chamber 13b. The discharged moisture may be circulated to the first drying chamber 13a and / or the second drying chamber 13b again through the dehumidifier 18 or may be discharged to the atmosphere through the air filter 19. [

The food garbage disposer having the above-described structure performs the fermentation and drying of the food garbage sequentially in one housing,

Hereinafter, another embodiment of the food waste disposal apparatus according to the present invention will be described.

6 to 9, the present embodiment differs from the above-described embodiment in the heating means.

The heating means of this embodiment includes a heating unit 130 for heating the air supplied from the housing 11 to a high temperature and a heating unit 130 having one end connected to the housing 11 and the other end connected to the heating unit 130, A suction line 151 for supplying air to the heating unit 130, a supply line 153 connected to the heating unit 130 at one end and connected to the housing to supply the heated air to the housing, And a blower 155 installed on the suction line 151 and an air circulation unit 150 installed in the suction line 151 or the supply line 153 to remove water, 170).

Here, the suction line 151 may be provided in all of the input chamber 12a, the fermentation chamber 12b, the first drying chamber 13a and the second drying chamber 13b, and in some cases, the first and second drying chambers 13a , 13b.

The heating unit 130 heats the introduced air to a high temperature to remove the malodorous component and supply the heated air. An intake port 132 communicating with the suction line 151 is formed on the lower side of the heating unit 130 A casing 131 on the upper side of which a supply port 133 communicating with the supply line 153 is formed; a heat insulating member 134 provided on the inside of the casing and in which the temperature sensor 139 is inserted in the lateral direction; A heating rod 135 vertically inserted into the center of the heat insulating member 134 and a heating rod 135 surrounding the heater rod 135 and communicating with the inlet 132 and the inlet 133 to heat the introduced air, Shaped heating space portion 137 formed in a cylindrical shape.

The casing 131 may be made of a metal material such as stainless steel.

The heat insulating member 134 is provided in the casing 131 to prevent the heat generated from the heater rod 135 from being discharged to the outside. The heat insulating member 134 may be a refractory material such as gypsum board wall, ALC, lightweight concrete, Can be exemplified.

A cylindrical heating space 137 is provided at the center of the heat insulating member 134. Since the heater rod 135 penetrates perpendicularly to the center of the heating space 137, Various harmful components contained in the air are burned or decomposed by the heat of the rod 135.

The heater rod 135 is made of a SiC material and generates heat at a high temperature of 800 to 1,200 ° C. when power is applied.

The heater rod 135 may have a spiral first guide member 136 formed along the outer circumferential surface thereof.

And a second guide member 138 having a helical shape corresponding to the first guide member 136 is formed on a wall surface of the heating space portion 137.

Since the first guide member 136 and the second guide member 138 are both formed in a helical shape, the air introduced through the suction port 132 is guided to rise while spirally rotating, The retention time is increased and the deodorization efficiency can be increased.

6, for example, the heat insulating member 134 may include an upper heat insulating member 134a and a lower heat insulating member 134b, And is coupled with the bracket 134e. The heating space 137 is formed in the lower heat insulating member 134b and the upper surface is partitioned by the upper heat insulating member 134a.

The second guide member 138 includes a cylindrical body 138a having an open top and a bottom and a spiral protrusion 138b formed on the inner circumferential surface of the body, And is fitted in the space portion 137.

The water removing unit 170 includes an auto drain unit 171 installed on the suction line 151 and an exhaust valve 161 for discharging a part of the air branched from the supply line 153 and having the odor- (173) may be exemplified.

The water removal unit 170 is formed on the suction line 151 and the exhaust valve 173 on both sides of the heating unit 130, thereby maximizing the water discharge efficiency.

The exhaust valve 173 can be controlled to be discharged at predetermined time intervals by employing a solenoid valve which is installed in a discharge line 153a branched from the supply line 153 and can be automatically opened and closed. The exhaust valve 173 may measure the air pressure or the vapor pressure through a pressure gauge or the like provided on the supply line 153, and then may be controlled to be opened when the reference pressure is exceeded.

The auto drain device 171 is also referred to as a moisture eliminator and corresponds to a well-known structure, and its detailed configuration will be omitted.

The reason why the auto drain device 171 is installed on the suction line 151 is because the heated air passing through the heating part 130 passes through the housing 11 and the temperature is lowered, The reason why the exhaust valve 173 is provided in the supply line is that the air flowing through the supply line 153 passes through the heating unit 130 and the harmful components are removed. There is no problem.
