Description

food waste disposal device

[0001] The present disclosure relates to a food waste treatment device, and more particularly, to a food waste treatment device capable of treating biodegradable plastics together with food waste.

[0002] Common methods for processing food waste include fermentation, incineration, recycling as feed and fertilizer, and landfilling. However, these methods not only require large-scale facilities, but also cause serious social problems such as environmental pollution and various side effects such as bad odors and inconveniences caused by collection, transportation, or storage.

[0003] Therefore, household food waste disposal devices are being developed and used to reduce environmental pollution caused by food waste and to recycle it.

[0004] This food waste disposal device can process food waste by drying, stirring, and crushing the food waste using the heat generated by the heater when the user puts it in.

[0005] Additionally, food waste can be processed using microorganisms. A microbial food waste treatment device can process food waste placed in a mixing bin by decomposing and destroying it through microorganisms.

[0006] Recently, biodegradable plastics that are broken down by soil bacteria or other organic organisms are being used in various ways to solve problems such as environmental pollution.

[0007] However, these biodegradable plastics take a long time to completely decompose, and there are many limitations, such as the need for large-scale sites for decomposition.

[0008] One aspect of the present disclosure provides a food waste disposal device capable of processing biodegradable plastic together with food waste.

[0009] One aspect of the present disclosure provides a food waste treatment device that can shorten the decomposition time of biodegradable plastics by utilizing a composting method using food waste, etc.

[0010] One aspect of the present disclosure provides a food waste treatment device capable of shortening the decomposition speed by enabling step-by-step control for decomposition of biodegradable plastic.

[0011] The technical problems to be achieved in this document are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0012] A food waste treatment device according to the invention comprises a housing forming an exterior, a stirring device provided inside the housing and configured to mix and crush a subject to be treated, and a storage device disposed below the stirring device and configured to change the physical properties of biodegradable plastic among the subjects to be treated using microorganisms and temperature or humidity.

[0013] A food waste treatment device according to the invention comprises a housing forming an exterior, a stirring device provided inside the housing and configured to mix and grind a subject to be treated, a drawer arranged below the stirring device and configured to modify the physical properties of a biodegradable plastic among the subjects to be treated using microorganisms and temperature or humidity, a water supply device for supplying moisture to the stirring device and the drawer, and a heating device for controlling the temperature of the stirring device and the drawer.

[0014] For example, a food waste disposal device can process biodegradable plastics along with food waste.

[0015] For example, the decomposition time of biodegradable plastics can be shortened by utilizing composting methods such as food waste.

[0016] According to an example, step-by-step control for the decomposition of biodegradable plastics is possible through multiple storage devices, thereby shortening the decomposition time of biodegradable plastics.

[0084] In this embodiment, the first angle between each stirring blade (122) and stirring shaft (121) is illustrated and described as being 72° depending on the number of stirring blades (122) and stirring shafts (121), but is not limited thereto. For example, the number of stirring blades and stirring shafts may vary depending on the size and shape of the stirring tank. The first angle may vary depending on the number of stirring blades and stirring shafts.

[0085] The stirring blades (122) of the stirring member (120) are arranged spaced apart from the center of the stirring shaft (121), and the stirring stands (123) can be arranged at each of the two ends of the stirring shaft (121). The stirring stands (123) arranged at both ends of the stirring shaft (121) are for stirring the microorganisms and the treatment target at the inner corner of the stirring tank (110).

[0086] The stirring member (120) has a stirring base (123) that is vertically connected to the stirring shaft (121) and can be formed by bending at least a portion thereof.

[0127] Figures 10 to 14 are drawings showing the operating state of a food waste disposal device according to one embodiment. Hereinafter, descriptions of parts overlapping with the above description are omitted.

[0128] As shown in FIGS. 10 to 14, the food waste treatment device (1) is capable of composting the treatment target, including biodegradable plastic.

[0129] A food waste treatment device (1) may include a separate storage device (200) that utilizes microorganisms and temperature or humidity according to the treatment stage of the treatment target, including biodegradable plastic.

The drawers (210) may include a first drawer (211), a second drawer (212), and a third drawer (213) arranged below the first drawer (211) and the second drawer (212).

[0131] Below, the operation of a food waste disposal device (1) for decomposing a treatment target including biodegradable plastics is described.

[0132] To compost biodegradable plastic (P1, hereinafter referred to as “first treatment target”) through a food waste treatment device (1), the first door (21) provided in the housing (10) is opened and the first drawer (211) is taken out. Microorganisms may be provided in the first drawer (211). The microorganisms may include soil or compost.

[0133] The user stores the first processing target (P1) in the first drawer (211). The temperature of the first drawer (211) can be set to 45 to 60°, and the humidity can be set to 45 to 65%.

[0134] When the first processing target (P1) is stored in the first drawer (211), the control unit (40) operates the water supply device (300) to maintain the humidity inside the first drawer (211) at 45 to 65%. The control unit (40) operates the heating device (500) to maintain the temperature of the first drawer (211) at 45 to 60°.

[0135] The humidity of the first drawer (211) can be maintained through the second valve (352) of the water supply valve (350) and the second water supply pipe (421). The temperature of the first drawer (211) can be maintained through the second heating wire (520).

[0136] The physical properties of the first treatment object (P1) can be modified by microorganisms and temperature or humidity within the first drawer (211). Specifically, the polymer chains of the first treatment object (P1) begin to break into smaller molecules, which is a branching step.

[0137] The first processing target (P1) stored in the first drawer (211) can have its physical properties changed using microorganisms and temperature or humidity without physical friction.

[0138] When the user puts the second treatment target (P2, hereinafter referred to as the “second treatment target”) into the stirring tank (110) to treat food waste (P2), the user puts the first treatment target (P1) together with the microorganisms stored in the first drawer (211) for a certain period of time. (See Fig. 12)

[0139] The first processing target (P1) and the second processing target (P2) are fed together into a stirring tank (110) and stirred by a stirring device (100).

[0140] *The first processing target (P1) is a step in which high molecular weights are broken down into low molecular weights, and physical friction is required to promote fragmentation. The first processing target (P1) and the second processing target (P2) experience physical friction inside the stirring tank (110).

[0141] When the first treatment target (P1) and the second treatment target (P2) are stored in the stirring tank (110), the control unit (40) operates the water supply device (300) to maintain the humidity inside the stirring tank (110) at 40 to 60%. The control unit (40) operates the heating device (500) to maintain the temperature of the stirring tank (110) at 40 to 60°.

[0142] The first treatment target (P1) is stirred and mixed and crushed together with the second treatment target (P2) by the stirring blade (122) and stirring plate (123) of the stirring member (120) rotating inside the stirring tank (110).

[0143] The control unit (40) controls the first water supply valve (350) so that the humidity inside the stirring tank (110) can be maintained at 40 to 60% through the first water supply pipe (411). The control unit (40) ensures that the temperature of the stirring tank (110) can be maintained at 40 to 60° through the first heating wire (510).

[0144] The first treatment target (P1) and the second treatment target (P2) stored and stirred in the stirring tank (110) can promote the step of cutting high molecules into low molecules through microorganisms, temperature or humidity, and physical friction.

[0145] The stirring member (120) inside the stirring tank (110) may be provided to provide physical friction between the first treatment target (P1) and the second treatment target (P2) so as to accelerate the decomposition speed of the first treatment target (P1) and the second treatment target (P2).

[0146] Inside the stirring tank (110), the first treatment target (P1) and the second treatment target (P2) are stirred by the stirring member (120) and can be finally decomposed by microorganisms and temperature or humidity. Mineralization is the process in which the substances that are finally decomposed into monomers are converted into water and carbon dioxide.

[0147] Composted soil, once decomposed and mineralized, can be used as soil for flower beds or flower pots, depending on the user's needs. Alternatively, composted soil, once decomposed and mineralized, can be stored in the first drawer (211) or third drawer (213) and reused, depending on the user's needs.

[0148] In this embodiment, the first processing target (P1) is described as being stored in the first drawer (211) and then moved to the stirring tank (110), but this is not limited thereto. For example, the first processing target (P1) may be stored in the third drawer (213) and then moved to the stirring tank (110) depending on its size and shape. Accordingly, the processing target can be stored in various ways depending on its size by drawers (210) having different sizes.

[0149] In addition, while the first processing target (P1) is stored in the first drawer (211), the user can additionally store the first processing target (P1) in either the second drawer (212) or the third drawer (213). Accordingly, it is possible to configure independent drawers (210) that can be controlled step by step according to the storage of the first processing target (P1), and the temperature or humidity can be controlled for each space step by step, thereby shortening the decomposition time.
