[0004]

2. Description of the Related Art As a conventional method for treating edible waste oil, there is a method for producing soap using a chemical agent (caustic soda). However, the problem is that the amount of soap consumed and the amount of waste oil processed are small.

In the laboratory experiment, it was reported that oil dregs fertilizer was produced from edible waste oil, but it took one month for lipolysis of the waste oil, and the fermentation period was further increased after adding actinomycetes. Since it takes a period of months, there is a problem in practical application in terms of production of the production apparatus and production cost. (1994, Research Presentation by the Japan Agricultural Club Federation)

It has been reported that fermenting materials for raw garbage and organic substances are fermented using microorganisms and processed at high temperature to produce compost. (For example, Patent. Open 03-50174, Open 04-26082, Open 06-72788, Open 01-27.
(For example, 5488, March 3 and December 4, December)

[Problems to be Solved by the Invention] Household waste oil in City A,
The amount of edible waste oil discarded from food service centers and restaurants is about 260 kl per year. As a processing method, a part is delivered outside the prefecture. Some are soaped. Part of it solidifies and is collected as household waste and incinerated. Since some of them are dumped, they are a source of pollution for rivers and lakes, and there is no appropriate treatment method.

In order to solve this problem, an apparatus capable of treating a large amount of waste oil in one process can be manufactured at low cost and installed in each convenient area for waste oil collection. Furthermore, the problem was not only that the production process and products were harmless and odorless, but that a product that could be reused should be made into a system that can be returned to the soil.

In order to achieve the above object, the edible waste oil treatment method of the present invention provides a device for setting a heat insulating device on the back side of the bottom wall of a cylindrical oil tank, and further connecting an inverter and a drive motor to allow stirring at a low rotation speed. We installed it and manufactured a waste oil treatment device that can perform low-temperature fermentation with microorganisms.

The edible waste oil, its adsorbate, and microbial culture powder are put into the oil tank of this apparatus to promote low temperature fermentation at a temperature suitable for microbial propagation of 30 ° C. In order to maintain this condition, heating and stirring are mutually repeated, and the edible waste oil is effectively treated as a regenerated product in a short period of time.

[0011]

[Operation] Waste oil is decomposed by the growth of microorganisms and low temperature fermentation to produce oil dregs. The regenerated product becomes neutral at pH 6.0 to 6.8 due to the enhanced antioxidant effect. When the mixture with waste oil is heated at 30 ° C, it begins to ferment in 48 hours. When the fermentation temperature of the mixture reaches 30 ° C,
The current is cut off by the action of the thermostat and the heating is stopped. Further, when the temperature becomes 30 ° C. or lower, the heating is continued and the heating is continued. When the heat of fermentation of the mixture rises to a temperature of 30 ° C or higher, the temperature is lowered by stirring and inserting air. In this way, since the low-temperature fermentation is constantly maintained, the function of producing regenerated waste oil from waste oil is produced in a short period of time.

[0004]

2. Description of the Related Art As a conventional method for treating edible waste oil, there is a method for producing soap using a chemical agent (caustic soda). However, the problem is that the consumer of soap and the amount of waste oil processed are small.

In an indoor experiment, it has been reported that actinomycete culture powder was used from edible waste oil to produce oil residue fertilizer. However, it took a month for lipolysis of waste oil, and actinomycete culture powder was also required. The fermentation period after the addition of 1 is required for another month. In this manufacturing method, since the manufacturing period is long, there is a problem in practical application in terms of manufacturing a manufacturing apparatus and manufacturing cost. Further, since sand is used as a fermentation catalyst, there is a problem in using it as a fertilizer. (Heisei 6
Fiscal year, research presentations sponsored by the Japan Agricultural Club Federation)

[0006] There is a report that fermenting materials such as garbage and organic substances are fermented by using microorganisms to produce compost by high temperature treatment. In such a conventional manufacturing method, there are many methods in which an organic material is dried at a high temperature and composted. However, the present invention is a method for producing a soil amendment that utilizes microorganisms as they are. (For example, Patent. Open 03-50174, Open 04

[Problems to be Solved by the Invention] Household waste oil in City A,
The amount of edible waste oil discarded from food service centers and restaurants is about 260 kl per year. As a processing method, a part is delivered outside the prefecture. Some are soaped. Part of it is solidified, collected as general waste and incinerated. Since some of them are dumped, they are a source of pollution for rivers and lakes, and there is no appropriate treatment method, so the development of appropriate treatment is an issue.

In order to solve this problem, an apparatus capable of treating a large amount of waste oil in a simple process is manufactured at low cost,
You can install a processor in each convenient area for collecting waste oil and use it anytime, anywhere. In addition to the chemicals used in the treatment process, the recycled product is not only harmless and odorless, but it is also a problem to build a system that can be recycled into a product that can be reused.

In order to achieve the above object, the first step is to manufacture a processing machine for effectively processing edible waste oil. The second stage is
We have developed a method for producing fermented oil dregs from edible waste oil, which is a recycled product of low temperature fermentation using microorganisms and can be effectively used.

The edible waste oil processing machine is a flat steel plate 2.3 m.
A fermented oil tank of 470 liters was prepared in a cylindrical shape using m, and a heat-retaining device with a sheath heater and a temperature controller with a thermostat were attached to the backside of the bottom wall. Furthermore, the wiring of the power supply is
Single phase 100V, the inverter and the drive motor are connected, and the stirring blade is rotated for 30 r. p. A stirring device capable of stirring at a speed of m or less was attached. And the breeding temperature of microorganisms 3
An equipment that can process waste oil by low-temperature fermentation while maintaining 0 ° C, and was made to a size that can be moved by a light truck.

The method for producing fermented oil residue is as follows: 20.0 kg of edible waste oil and 35.0 kg of rice bran as a fermenting material, 5.0 kg of sawdust, 2.0 k of smoked charcoal in a fermentation oil tank of a waste oil processor.
g, and after mixing, sodium bicarbonate 42.0
g, salt 40.0 g, calcium silicate 75.0 g, L
After adding 1.5 g of ipase and stirring, the mixture is kept warm at 30 ° C. for 48 hours. After 48 hours, 620 g of the lactic acid bacterium culture powder, 620 g of the yeast culture powder, and 620 g of the actinomycete culture powder were added and mixed with stirring. After that, in order to maintain the low temperature fermentation at 30 ° C., heating and stirring are mutually repeated to adjust the fermentation temperature, so that fermented oil cake can be produced from waste oil in a short period of time.

[0012]

[Operation] By maintaining the heat and stirring the processing machine, the growth of microorganisms and the low temperature fermentation are maintained, whereby the waste oil is decomposed and the oil residue is produced. The regenerated product becomes neutral at pH 6.0 to 6.8 due to the enhanced antioxidant effect. When the mixture with waste oil is heated at 30 ° C, it begins to ferment in 48 hours. When the fermentation temperature of the mixture reaches 30 ° C or higher, the current is cut off by the action of the thermostat and the heating is stopped. Further, when the temperature becomes 30 ° C. or lower, the heating is continued and the heating is continued. When the heat of fermentation of the mixture rises to a temperature of 30 ° C or higher, the temperature is lowered by stirring and inserting air. In this way, since the low temperature fermentation is always maintained, the function of producing fermented oil residue, which is a regenerated product, from waste oil occurs in a short period of time.
