Description
Technical Field
The invention relates to an odor converting agent for kitchen garbage and an odor converting method for kitchen garbage.
Background
At present, garbage generated from a household or the like in daily life is collected by a garbage collection vehicle. Specifically, in a street, garbage is generated in a garbage collection place, a garbage collection vehicle arrives at the garbage collection place, and an operator drops and collects the garbage from a garbage input port of the garbage collection vehicle and transfers the garbage to the next collection place. After collection, the garbage collection vehicle travels along the street, is transported to a garbage disposal site, and is disposed of in the garbage disposal site.
Among the garbage, especially kitchen garbage generates offensive odor. In a place where garbage is collected, there is a problem that the generated garbage gives off offensive odor. There are the following problems: after the garbage is collected, the liquid generated from the garbage is leaked to the collection place, and the offensive odor is attached to the collection place.
In addition, there is a garbage collection vehicle of a type having an opening for a garbage inlet, and there are the following problems: when the garbage collection vehicle runs in the street during the collection of the garbage, the offensive odor is scattered.
As a means for suppressing the spread of offensive odors, a garbage collection vehicle provided with a deodorizing device has been proposed (for example, see claim 4 of patent document 1).
However, there are problems as follows: the odor of the kitchen waste is difficult to be deodorized, and even if a deodorizing device such as a deodorizing device or a deodorizing agent is used, the odor cannot be sufficiently deodorized.
Therefore, there is a demand for development of a technology capable of solving the problem caused by the bad odor of the kitchen waste.

Examples
The present invention will be described in detail below with reference to examples. However, the present invention is not limited to the examples.
(preparation of odor converting agent for kitchen garbage)
The raw materials shown in table 1 were charged into a mixing tank, mixed and stirred to prepare an odor conversion agent for kitchen waste. Specifically, the odor converting agent for garbage of example 1 was prepared by charging a solvent in accordance with the formulation shown in table 1 into a mixing tank equipped with a heating device, sequentially adding other raw materials, and stirring at 20 ℃ for 30 minutes.
(evaluation)
The odor converting agent for kitchen garbage of example 1 prepared as described above was used to perform the following evaluation. That is, a filter paper was placed on a sterilized petri dish (schale) for bacteria examination, and 1g of sewage stored in a sewage tank of a garbage collection vehicle was dropped into the center of the filter paper. Next, using the kitchen waste odor converting agent of example 1 prepared as described above, a 0.1 mass% ethanol solution of the kitchen waste odor converting agent of example 1 was prepared. Then, 0.1g of the ethanol solution was dropped around the dropped sewage to prepare a sample. As shown in table 1, the sewage was collected in 6 places in the island and 3 places in osaka.
Next, the sample was covered with a petri dish (schale) and allowed to stand at room temperature (20 ℃) for 10 minutes. After standing, the lid was opened, and the subject smells 10cm above the center of the petri dish and subjected to sensory evaluation according to the following evaluation criteria. The test was performed by 5 persons, and evaluation was performed using a value obtained by rounding the average of evaluation values.
5: no odor of the kitchen waste was sensed, and a very good odor was sensed.
4: the odor of the kitchen garbage is hardly felt, and a good odor is felt.
3: some kitchen waste odor was perceived, but no unpleasant sensation was perceived.
2: the odor of the kitchen garbage is sensed, and no good odor is sensed.
