BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention relates to an apparatus for liquidizing organic substances that is capable of, at each household, easily liquidizing-processing organic waste, such as kitchen refuse, discharged from a usual household in a short time while preventing generation of an offensive odor so as to reduce the quantity of the waste, and as well as enabling the thus-liquidized substances to be easily separated and taken out so that the liquidized substances are used mainly as liquid fertilizer or the like.
2. Background Art
Under present conditions, kitchen refuse discharged from usual households, garbage generated in restaurants or fields relating to food and excrement of animals in the livestock industry or the like have been thrown away without any utilization of the same. The amount of generation of such organic waste has been increased every year, and therefore loads for the waste disposal plants become heavier. In particular, a new waste disposal plant cannot substantially be founded in urban regions, thus causing a critical social problem to arise. From another viewpoint of the resource recycle, the disposal of the foregoing organic waste without recycling results in an extravagance of the limited source.
Accordingly, a waste disposal container of a type capable of, at each household, composting kitchen refuse discharged from a usual household has been developed. However, such waste disposal container takes a long time to compost the kitchen refuse and, therefore, a large-size waste disposal container is required to dispose the kitchen refuse discharged from a household. Furthermore, bad smelling inhibits use of the waste disposal container of the foregoing type in residential areas in urban regions.
In order to raise the disposing speed, a method has been found which comprises the steps of adding water and microorganisms to the kitchen refuse in small quantities required, forcibly decomposing (fermenting and digesting) the kitchen refuse to liquidize the kitchen refuse and to mature the same so that the matured substances are used as liquid fertilizer or the like. The method enables substantially all kinds of kitchen refuse to be liquidized in a short time. Furthermore, split-sampling of the liquidized substances as liquid fertilizer or the like results in that the quantity of residual solid materials can be reduced considerably. While paying attention to the foregoing fact, the applicant of the present invention has developed and applied for patent a method that uses microorganisms to produce liquid fertilizer from kitchen refuse (refer to Japanese Patent Laid-Open No. 5-872).
Although the foregoing process can be completed by using a plastic bucket for usual households, use of the simple bucket involves a difficulty in separating the residual solid materials and the liquidized portion after the liquefaction process has been completed. In addition, the liquidized portion cannot easily be maintained at a suitable liquidized (decomposed, fermented and digested) condition under which the same is used as the liquid fertilizer or the like. In order to raise the liquidizing speed, it is effective to grind, stir and aerate the kitchen refuse and to heat the same to a certain temperature (at which microorganisms grow easily and functions of enzymes of the microorganisms are facilitated). Since the foregoing disclosure has been structured on an assumption that the usual plastic bucket is used, a satisfactory liquidizing apparatus has not been obtained. Therefore, the foregoing disclosure cannot easily satisfy a variety of liquidizing conditions, and thus use of the same at usual households has encountered a problem.
That is, a liquidizing apparatus for use in usual households for liquidizing organic substances, such as kitchen refuse, must meet the following requirements: separated from each other; state where the same can be used as liquid fertilizer or the like, is required; so that leakage of bad smell is prevented; the inner chamber is placed in the liquid so that generation
