Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application This invention relates to the improvement of an apparatus that can be used to ferment organic matter at high speed to produce fertilizers, feeds, and the like.

(B) Prior Art Conventionally, devices using microorganisms have been developed for high-speed fermentation of organic substances, but these devices were insufficient in terms of cost, efficiency, handling, etc.

(C) Problems to be Solved by the Invention The present invention aims to improve the above-mentioned drawbacks by incorporating a hot water heater into the tilting stirrer and making it easier to adjust the air and temperature according to the fermentation speed. The purpose is to

(D) Means for solving the problem Next, the means for solving the problem will be explained with reference to drawings showing embodiments.

(a) Example 1 For example, a stirring spiral 2 is formed on the inner wall of a daruma-type tilting rotary drum 1, and the support stands 14, 15 are formed.
The tilting rotary drum 1 is tilted upward and fixed by a support roller 4, and the upper part of the tilting rotary drum 1 is open to the organic matter input hopper 5, the exhaust fan 6, and the fermented product discharge chute 16. By providing a swivel 19 on the rotating shaft at the bottom of the unit, a hot water heater 7 is built in, and hot water is circulated through the boiler 10 and the boiler 10 in the direction of the arrow through the circulation pump 20, the hot water supply pipe 8, and the circulation pipe 9, and the blower 12 It is characterized in that it is sealed so that air ration 13 is generated inside as shown by the arrow, and only the tilting rotary drum 1 can be rotated in forward and reverse directions as required by the drive gear 3. This is a high-speed organic matter fermentation device.

(B) Example 2 In two tilting rotary drums 1', 1'', a boiler 10', a circulation pump 20' and a blower 12'
A high-speed fermentation device for organic matter that also serves as

(E) Effects of the Invention Since the present invention has the above-described configuration, when it is used, organic matter and fermentation microorganisms are mixed into the tilting rotary drum 1 from the input hopper 5, and the stirring spiral The tilting rotary drum 1 is rotated by the drive gear 3 so as to move the organic matter downward by the blower 12, and the organic matter is agitated by continuing the rotation. A suitable amount of oxygen is supplied by adjusting the air by raising the temperature, and a suitable temperature is maintained by the hot water heater 7. Then, carbon dioxide, water vapor, etc. generated in the tilting rotary drum 1 are sucked out by the exhaust fan 6 as shown by the arrow 11 to provide favorable conditions for fermentation. Thus, when the fermentation of the organic matter is completed, the tilting rotary drum 1 is rotated in the opposite direction and the fermented product is carried out from the discharge chute 16 as shown by the arrow 17.

Therefore, the temperature inside the tilting rotary drum 1 is
For example, the temperature can be adjusted to 55° to 60°C using a hot water heater 7, and the amount of air required can be adjusted using an exhaust fan 6 and a blower 12 to supply oxygen in accordance with the fermentation rate.

Test results have shown that it is possible to provide an efficient, inexpensive, and easy-to-handle organic matter high-speed fermentation device, which is applicable to food scraps such as animal and plant residues, livestock manure, wood waste, grass, sprouts, and vegetables. It can be applied to various organic matter such as leaves and stems.

(G) Other Examples In addition, as shown in Example 2, the present invention makes it possible to use an energy-saving boiler by utilizing fermentation heat as shown in the arrow. For example, as in Example 2, current technology such as a heating method in place of a hot water heater can be widely applied.
