Description

[Detailed Description of the Invention] This invention aims to effectively utilize and process a large amount of rice husks generated at rice centers, etc. for the production of fermented compost as an effective treatment for breeding poultry and sludge. The present invention relates to a method for producing fermented compost using rice husks as a moisture regulating material.

Compost is produced by mixing main raw materials such as hoarded poultry beds and sludge with fermentation accelerators and moisture regulators to create a fermentation raw material with a moisture content of 60 to 70%, and fermenting this in a fermentation tank. is a well-known method, but when rice hulls are used as a moisture regulating material, unless they are pulverized, they not only do not have the moisture regulating effect, but also cannot be ashed.

In other words, rice husks that are not crushed (hereinafter referred to as the current state of rice husks)
60 to 7 because it is hard and has no water absorption effect at the raw material stage.
In order to obtain a raw material for fermentation with 0% water content, a large amount of rice husks must be added.

Moreover, when this is put into the fermentation tank, the rice hulls and other ingredients are separated due to differences in specific gravity, etc., and it becomes easier to absorb water during the fermentation stage in the fermentation tank, resulting in a lack of water in the fermentation raw material. The disadvantage is that fully ripened compost cannot be obtained.

For this reason, when rice hulls are used as a moisture control material, they are crushed, but it is difficult to keep up with the current processing of large amounts of rice hulls generated at rice centers and the like.

In view of the above-mentioned conventional techniques and the requirements for rice husk processing, we have invented a method for producing fully ripened compost using the current state of rice husks, and the detailed description will be as follows.

That is, sludge discharged from a floor treatment plant is subjected to aerobic fermentation and sun drying to reduce the moisture content to about 20%, and a fermentation accelerator or chicken manure is added to the main raw materials of manure and sludge, and the present condition is added to this alone or with rice husks. In addition to sawdust and hay, it is used as a raw material for fermentation, and in the process of supplying this raw material for fermentation to the fermentation tank using a transfer screw, a band material is screwed onto the tip of the support supported by pillars planted radially in the diametrical direction of the main shaft. A rice husk characterized in that the rice husk is fed to a fermentation tank after passing through a stirring mixer arranged in the oblong body using a special screw that is connected to the formed state and thereby creates a space between the main shaft and the strip material, and is then fermented. The gist of this paper is a method for producing fermented compost using fermented compost as a moisture regulating material.

As described above, before feeding the fermentation raw materials sent from each tank, which are appropriately mixed in volume ratios, into the fermentation tank, in addition to the stirring and mixing that occurs during transfer by the screw conveyor, the fermentation materials are mixed radially in the diametrical direction of the main shaft. In order to mix and knead the material using a special screw, the strip material is connected to the tip of the vertical column in a screw-forming state using a vertical column as a support, thereby forming a space between the main shaft and the strip material. The rice husks that have absorbed water are transferred to the strip material, where they are struck by the support in the space between the strip material and the main shaft, and are loosened by the violent rubbing and compression of the materials, resulting in a water-absorbing state, i.e., rice husk. The rough texture on the surface of the pulp is removed, the fibers are exposed, and this changes to a state where it is kneaded and loses its hardness.

For this reason, at the stage where the ingredients are fed into the fermentation tank after passing through the stirring and kneading device, the ingredients are mixed evenly without being separated due to differences in specific gravity, etc., and the moisture content is adjusted to the level suitable for fermentation due to the current moisture absorption of the rice husks. It becomes a raw material for fermentation of 60-70%, and the primary fermentation can be completed without causing moisture shortage, and the fermented material that has completed the secondary fermentation in the dumping ground and the tertiary fermentation by cutting back is as good as rice husks. It can be made into fully ashed, fully matured compost.

In this way, rice husks can be effectively used as a moisture control material without the need for pulverization or other effort, making it possible to produce high-quality compost at a low cost and that can handle the current processing of large quantities of rice husks generated at rice centers, etc. It has the effect that it can be manufactured and provided.

Claims (1)

[Claims] 1 Fermentation accelerator or chicken manure, which has made the sludge discharged from the N urine treatment plant have a moisture content of about 20% by aerobic fermentation and sun drying, is added to the main raw materials of manure, urine and sludge, and the present state of rice husks is added to this either alone or by In addition to scraps, hay, and other materials, it is used as a raw material for fermentation, and in the process of supplying this raw material for fermentation to the fermentation tank by a transfer screw, a band material is formed at the tip of the screw supported by struts planted radially in the diametrical direction of the main shaft. This method is characterized in that the rice husks are fed through an agitating and kneading machine in which a special screw connected to the main shaft and thereby creating a space between the main shaft and the strip material is placed inside the oblong body, and then the rice husks are fed to a fermentation tank for fermentation. A method for producing fermented compost used as material.
