BACKGROUND OF THE INVENTION
The present invention relates to a composting facility and a composting method, and more particularly, to a composting facility and a composting method that can reduce the size of the facility, improve hygiene, and increase the efficiency of composting work during operation.
[0002]
[Prior art]
Various developments and improvements have been made to facilities, devices, and composting methods for "composting" processing technology that uses livestock excreta such as livestock manure.
[0003]
The open-type composting device, which is widely used as a composting method, promotes composting by aerobically decomposing and maturating livestock excrement through the material mixing process and the reversing process by transfer. There are linear, circular and elliptical (circular) devices. Among them, in the conventional linear composting apparatus, the secondary treatment (secondary fermentation) passes through the primary fermentor that performs the primary treatment, and the height of the secondary treatment (secondary fermentation) is high in a stockyard such as a compost house. Generally, it is a method of depositing to about 2 m, or extending a straight-type composting apparatus and turning it over. Moreover, as a primary fermenter of a stirring type open type linear composting apparatus, it generally has a flat area of 2 to 6 m in width and 20 to 60 m in length, and the ground is dug down to a depth of about 0.3 to 2 m. There are many concrete structures with an open top surface that are shaped like pits (see Non-Patent Document 1).
[0004]
As materials used in the composting process, there are mainly compost raw materials and auxiliary materials. As compost raw materials, the main thing is livestock excrement such as beef dung, pork dung, chicken dung, etc., and there are cases where it is handled including waste vegetables and food residues. Secondary materials are mixed with livestock excrement to increase porosity and improve air permeability, and include rice straw, rice straw, sawdust, bark, and back compost. A screw conveyor, a belt conveyor, a small mixer, a feed stirrer and the like have been modified and used as a mixing apparatus used for mixing these compost raw materials and auxiliary materials.
[0005]
Further, as described above, the composting process is generally a combination of the primary process in the primary fermenter and the secondary process (secondary fermentation) as the next process. The primary treatment is performed for the purpose of decomposing readily degradable organic substances that cause growth failure when compost material is applied to crops, and the treatment period is expected to be about 15 to 25 days. Then, the compost is stabilized by further ripening in the secondary treatment (see Non-Patent Document 1).
[0006]
The turning device installed in the primary fermenter is used to stir, mix or turn the compost raw material and auxiliary materials (hereinafter referred to as compost material) while moving straight on the rail installed on the top or side of the fermenter. And has the function of composting. Scoop type, paddle type, rotary type, and composting crane type are known as the mechanism of the turning device (see Patent Document 1). The compost material is turned over by stirring and mixing once or twice a day with a turning device that runs in the upper part of the fermenter, and is composted while being transferred little by little, or transferred to the secondary fermentation area. Reversing by replacement is performed periodically and composted.

[0008]
The scoop type is a system in which a scraping horizontal bar attached to a chain picks up compost material diagonally and turns it back while dropping it in the direction of travel. It is used in deep fermenters with a turnover depth of 1 m or more. ing. In the linear composting apparatus, after turning over, the scraping apparatus is lifted upward and moved rearward so as not to come into contact with the material so as to return to the starting point.
[0009]
[Problems to be solved by the invention]
By the way, the above-mentioned mixing apparatus has a problem that the composting promotion state changes depending on the mixing state of the composting material, so that uniform mixing cannot be performed while maintaining porosity. The pressure mixer is a device that pressurizes and mixes livestock excrement and return compost, and is expected to increase the material temperature and evaporate moisture with the heat generated by the pressurization. Is a pre-treatment machine that promotes composting by performing physical heating, and in order to promote composting by aerobic microorganisms, after passing through a mixing device, composting by deposition or agitation method is performed. There are drawbacks such as reducing the voids of the compost material by applying pressure.
[0010]
In addition, the conventional open / linear fermenter has a sheet-like cover on the top of the fermenter, but there is no sealed type, which requires maintenance costs for odor and ventilation. May occur.
[0011]
In addition, when the scoop type turning device described above is used, compost material is stuck between the scraping bar of the device and the bottom and both walls of the fermenter, and the scraping bar, and the removal work of the stuck compost material There are many maintenance work such as cleaning and cleaning. In addition, this type of apparatus has a problem that stirring cannot be sufficiently performed, the compost material tends to be lumpy, and the amount of returned compost increases.
[0012]
In addition, in the conventional composting facility, when the material is put into the fermenter, the composting material is put into the hopper without being mixed, and then conveyed by a belt conveyor or the like by the pushing operation of the lower hopper screw. Other materials and moisture adjusting materials were also put into the fermenter as they were. After that, the compost material put in the fermenter is agitated and turned over, but because the compost material is not sufficiently mixed in the composting process, it becomes agglomerated or returns 40-50% of the amount of compost produced. The composting period tends to be prolonged, and the production cost is high. Also, as a problem caused by the stirring method of the device, when using a conventional rotary type or scoop type conveying / turning device, if a material with a lot of moisture is put in one place, it tends to become a lump and aeration It was necessary to remove clogging on the floor, and the device was overloaded, causing failure. Further, the compost produced in such a situation has a poor balance between the material and the moisture adjusting material, and the quality varies.
[0013]
Therefore, the object of the present invention is to eliminate the problems of the conventional techniques described above, and in a compact composting facility, primary composting and secondary fermentation can be efficiently performed so that composting can proceed. It is to provide composting facilities and composting methods.
