Abstract

PURPOSE:To improve the rate of fermentation treatment by charging a warmed fermentation room with fermenting fungi and org. waste of controlled water content, pressing and agitating the waste with a screw press hammer to ferment and then aging and drying the waste in an aging and drying room in the next stage. CONSTITUTION:Fermenting fungi are mixed with org. waste containing water preliminarily controlled, and the mixture is introduced to a fermentation room 4 through the supply port 5 of a treatment tank 1. The waste is pressed and agitated with a screw press hammer 9 in the fermentation room 4 kept at 55-60 deg.C where lumps or grains are pulverlized into a uniform state and left to stand to accelerate the decomposition effect of the fermenting fungi. Then the fermented product in the fermentation room 4 is transferred with a carrier screw 8 to an aging and drying room 6, where the product is again pressed and agitated with a screw press hammer 9 to promote uniform aging. Malodor produced in the fermentation process is decomposed by fungi in soil and reformed and deodorized. By leaving the fermented product for a specified period, the waste is converted into a valuable product completely fermented in a aged and dried powdery state and recovered as an org. fertilizer or fermented feed through a discharge port 7.

Description

[Detailed Description of the Invention] [Purpose of the Invention (Industrial Application Field) This invention provides an excellent organic fertilizer by biotechnologically and physicochemically fermenting organic waste at high speed. It relates to means for producing fermented valuables such as food and feed.

(Prior art) Until now, organic waste such as garbage has been treated chemically, incinerated, or dumped in a designated place. There are restrictions due to regulations and other factors, and it is also causing serious problems such as contamination of the global environment due to secondary pollution.

(Problems to be Solved by the Invention) In view of the above-mentioned conventional circumstances, the present invention is based on the idea of converting the above-mentioned waste into recycled resources, utilizes biotechnology, and combines this with a physicochemical treatment tank. This provides a means to produce high-quality fermented feed and organic fertilizer without pollution and at high speed.

[Configuration of the invention (Example) To explain the following with reference to the embodiment of the drawings, in FIGS. This is a processing tank 1 having a predetermined volume and provided in sections.

A heater 3 is provided on the floor surface 2 of the entire processing tank 1, and a conveying screw 8 driven by a motor Ml is installed at the bottom of the fermentation chamber 4, with its tip 8a penetrating the partition wall 1a for ripening and fermentation. It is provided facing the bottom of the drying chamber 6.

Further, a screw press hammer 9 driven by a motor M2 is mounted on a shaft extending through both chambers 4.6.

In addition, in the drawing, 10 is a control panel, and 11 is a vent.

(Function) Now, in order to use the high-speed fermentation processing machine with the above configuration, it is necessary to
Time (approximately three days) as a processing period, (-8th) First, switch on the heater 3a of the fermentation chamber 4, adjust the room temperature to 55°C to 60°C, and start the motor M2. to rotate the screw press hammer 9.

Then, fermentation bacteria are mixed into food waste whose water content has been adjusted in advance, and the mixture is charged into the fermentation chamber 4 through the input port 5.

Then, the screw press hammer pressurized 90 times,
Due to the stirring and pounding action, thick lumps and grains are crushed and lose their shape, and by homogenization, conditions are created that facilitate fermentation as a whole. Thereafter, the screw press hammer 9 is stopped and left standing for a predetermined period of time to promote the decomposition action by the fermenting bacteria.

In this case, if the indoor temperature is 70°C or higher and the moisture content is 70% or higher, most of the bacteria will die, but if the indoor temperature is 30°C or lower and the moisture content is 30% or lower, most of the bacteria will die. Be careful, as the bacteria will go dormant if left untreated.

(Second day) Next, switch on the heater 3b in the ripening/drying room 6, adjust the room temperature to 55°C to 606°C, and turn on the motor M.
2 is started to rotationally drive the conveying screw 8, and the screw press hammer 9 is operated in the same manner as before.

Then, the fermented product in the fermentation chamber 4 is transferred to the conveying screw 8.
It is transferred to the ripening/drying chamber 6 by the screw press hammer 9, and is rotatably pressed, stirred, and pounded again by the screw press hammer 9 to roughly break it into fine pieces and make it into fine particles, thereby promoting uniform ripening.

After a predetermined time has elapsed, the screw press hammer 9 is stopped and placed in a stationary state again.

The temperature conditions and oxygen conditions in the room are approximately the same as in the fermentation room.

In addition, the bad odor generated in the above process, namely ammonia scum and amine gas produced during the decay of organic matter, hydrogen sulfide produced by the decay of proteins and meat, glucose produced by the decomposition of cellulose, and their mixed gas, is caused by ammonia in soil bacteria. By feeding oxidizing bacteria, sulfur bacteria, and cellulose-degrading bacteria, it is decomposed into carbon dioxide gas, water, sulfuric acid, cuff acid, acetic acid, and methane, resulting in alteration and deodorization.

(third day) Finally, leave it in that state for nine days.

During this retention process, the ripened product is fully ripened and dried, becoming a completely fermented valuable product in the form of powder. Then, the heater 3b is switched off, the screw press hammer 9 is rotated again, and the product (fermented fertilizer, fermented feed) is discharged from the discharge port 7.

[Effects of the Invention] As described above, the present invention is capable of fermenting organic waste such as raw garbage that is generated every day into high-quality fermentation without pollution and at extremely high speed through the cooperation of biotechnology and mechanical engineering. Converted into valuables, such as fermented feed and organic fertilizer.

A comparison between the fermentation process according to the present invention and a general fermentation process pattern is shown in FIG.

From the above, the present invention is truly advantageous in that it contributes to resource recycling, helps prevent environmental pollution, reduces dependence on chemical fertilizers and pesticides, and improves crop growth conditions. .
