Abstract

PURPOSE:To reduce a treatment smell and to prolong the life of a culture base material, in a garbage treatment machine subjecting garbage to decomposition treatment under stirring by the action of bacteria, by mixing coffee grounds with the culture base material composed of sawdust. CONSTITUTION:A rotary shaft 3 supporting stirring blades 2 is provided to the central part of the main body of a garbage treatment machine 4 and a garbage throwing-in port 6 is provided to the upper part of the garbage treatment machine 4 and a receiving box 9 for taking out a culture base material 5 is arranged to the lower part thereof so as to be capable of taken in and out in the back-and-forth direction of the main body. Garbage is subjected to decomposition treatment by the culture base material 5 received in the treatment machine 4. In this case, the culture base material 5 is formed from sawdust based on a fiber hard to decompose such as lignin and coffee grounds and, pref. the particle shape thereof is uneven and voids are formed between particles. The mixing ratio of sawdust and coffee grounds is set to 90:10%. By this constitution, an unpleasant treatment smell is eliminated and the formation of lumps is relaxed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal device for decomposing food waste generated in general households by using microorganisms, and in particular, agglutination and odor diffusion of a culture substrate in the decomposition process. Regarding prevention.

[0002]

2. Description of the Related Art In a method of using a culture substrate of this type of garbage treating machine, the use of sawdust, rice husks, etc., alone is the mainstream.

[0003]

In the conventional method, sawdust is used as a single substance, and although it has a capability of decomposing food waste, there are some cases in which agglomeration and odor diffusion are remarkable during the process.
Also, the life of the culture substrate is extremely shortened.

An object of the present invention is to eliminate these drawbacks and to provide an easy-to-use garbage disposal machine.

[0005]

The present invention can achieve the above object by mixing coffee grounds with a culture substrate, which is sawdust, and decomposing the same in order to eliminate discomfort to the user.

[0006]

[Operation] The culture base material mixed with sawdust and coffee grounds when the outer lid is opened eliminates the discomfort to the user from the odor of coffee grounds, and at the same time reduces the agglomeration and prolongs the life of the base material. This will further improve the handling for the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the present invention will be described in detail below with reference to FIGS.

FIG. 1 is a perspective view for explaining the principle of the garbage processing machine of the present invention.

In FIG. 1, reference numeral 1 denotes a main body of a garbage processing machine, which rotates about a rotary shaft 3 supporting a stirring blade 2 in the center as shown by an arrow. A culture substrate 5 is contained in the food waste processor 4, and a food waste inlet 6, an inner lid 7, and an outer lid 8 are provided on the upper portion,
It has a double lid. A door switch (not shown) is interlocked with the outer lid 8 so that the door switch is turned off and the stirring blade is stopped when opened at a certain angle.
Further, a packing for sealing is provided between these lids and the receiving surface. In the lower part, a storage box 9 for taking out the culture substrate 5 is provided with a handle 10 at the tip, and is arranged so as to be able to be taken in and out in the front-back direction of the main body 1. The culture substrate 5 is composed of sawdust and coffee grounds whose main components are fibers that are difficult to decompose, such as lignin, and each grain is porous and has voids, and the grain shape is complicated and uneven. And a large void is formed between the grains. The mixing ratio is 90% of sawdust and 10% of coffee grounds. FIG. 2 is a vertical sectional view showing the overall internal structure.

The internal structure of the main body 1 will be described with reference to FIG. It is rotated by a drive motor 11 via a transmission mechanism 12 such as a chain or a belt. Fresh air is sucked into the upper part of the processing tank through the ventilation fan 13 and the intake port 14, and the gas in the processing tank is discharged to the outside of the machine through the exhaust port 15. Filters are provided at the intake port 14 and the exhaust port 15, respectively.

At the bottom of the processing tank, the contents are dropped from the discharge port 16 into the discharge path 17, so that the contents can be taken out to the outside of the main body.

Before operation, water is added to adjust the water content of the culture substrate 5 from 40% to 60%, and necessary microorganisms are added and stirred to form a bed for microbial propagation. After that, just open the lid every day, add garbage and close the lid. The device automatically repeats stirring and ventilation at regular intervals. Garbage is crushed by being stirred together with the culture substrate and rubbed against the particles of the uneven culture substrate to be worn, and the surface is contacted with the enzyme secreted by the microorganism and decomposed until it becomes a single molecule. When the microorganisms are decomposed to a level where they can be easily taken up, this is taken up as an energy source and reproductive activity is performed. That is, due to the respiratory action at this time,
Eventually, it changes to minerals (carbon dioxide, water vapor, trimethylamine, methyl mercaptan, etc., which cause malodor) and fermentation heat. These are discharged outside the machine by a ventilation fan.

Here, agglomeration of the culture substrate 5 of the present invention and prevention of odor diffusion will be described.

When a suitable amount of coffee grounds is added to the sawdust of the culture substrate, it is uniformly mixed by a stirring blade. The food waste put in the treatment tank is decomposed by the reproductive activity of microorganisms, but the coffee dust is denser and harder than sawdust, so that the crushing by stirring is further promoted. In addition, since it emits a unique smell of coffee grounds that is different from sawdust alone, the user does not feel any discomfort due to the odor when opening the lid and throwing in garbage every day. In addition, when sawdust is used alone, the uneven base material wears quickly due to the stirring action in the process of decomposing food waste, and the material that easily absorbs water accelerates the filling of the voids in the base material, so oxygen to microorganisms is reduced. Replenishment cannot be performed properly, and at the same time, the material is agglomerated, and the life of the base material is further shortened.

Next, processing by mixing sawdust and coffee grounds will be described.

[0016] The sawdust simple substance has a large gap between grains and easily absorbs moisture when food waste is thrown in. Therefore, the waste that has been crushed by moisture and agitation gradually shrinks the gap and shrinks. It is easy to become. Therefore, agglomeration progresses rapidly. Mixing sawdust and coffee grounds is very hard unlike sawdust alone, so when you throw in the garbage, the garbage is crushed quickly by stirring. Further, the water of the food waste is quickly absorbed by the sawdust, but since the coffee grounds are uniformly mixed, the effect of preventing agglomeration penetrates around the coffee grounds. Coffee also has the property of not absorbing water directly and not attaching sawdust to the grains. Therefore, a gap with the sawdust is kept near the coffee grounds to prevent agglomeration, and at the same time, when agitated, the agglomerated part due to the hard nature of the coffee aroma is gradually scraped off by abrading and agglomerated. Prevent. Therefore, supplementing oxygen to microorganisms can also be done with sawdust,
Since coffee lumps do not easily agglomerate, they can be sufficiently processed and the decomposition processing capacity can be actively performed, so the life of the base material is extended, so that the user can replace the base material and handle it easily. Is further improved.

[0017]

According to the present invention, there is provided a garbage disposal device which reduces the processing odor at the time of throwing food waste into a conventional product and further extends the life of the base material to improve the discomfort and the handleability for the user. Can be provided.
