CONSTITUTION:This composting device disposed with heat insulating pipes 1H on the floor surface of the fermentation tank. A roof 1F constituted of a synthetic resin plates 1F2 composing of light transmissive synthetic resin sheets 1F1 and vent holes 1F21 extended at specific intervals is arranged at this device. Suction pipes 1j disposed in the ridge part enclosed with the synthetic sheets 1F1 and the synthetic resin plates 1F2 are connected to lower pipings 11. Hot air 1H and lower pipings 1I are connected by a blower 1K. The blower 1K is first operated by this device and immature bark compost is laid over the entire floor surface. The compost temp. is kept at >=60 deg.C. The crude dung is then charged onto the immature bark compost. The fermenting and drying state is well maintained by the sunlight, the terrestrial heat and heat of fermentation, etc., and the compost is agitated for one to two weeks. The compost is moved from the fermentation tank and is deposited after three to four weeks.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cow manure continuous drying / fermentation composting apparatus and a method of using the same. In the era when agriculture was carried out in the organic relationship of soil, grass and cattle, the manure treatment of livestock was not a big problem,
As the scale of business became larger and specialized, the problem became apparent, and now it is one of the issues to be addressed immediately not only in the suburbs but also in rural communities. not to mention,
The treatment and utilization of livestock manure is currently a very important issue for both organic and environmentally-friendly or sustainable agriculture, and good compost produced by a farm with a well-equipped treatment system is important for crop production. It is an essential organic fertilizer and soil improvement material for maintaining and improving productivity and quality.

However, if the handling is wrong one step, it will cause environmental pollution such as generation of harmful insects and odors, water pollution of rivers, etc., and there is a possibility that Japan will be subject to the strict legal regulation like Europe in the near future. Therefore, from a global perspective, it will be necessary to promptly build a global environment-friendly livestock management that does not cause pollution such as air pollution, water pollution, and soil pollution. Appropriate manure treatment is to make the living environment / living space comfortable for both humans and livestock, which in turn leads to improvement of the rural landscape (rural environment). How to effectively utilize livestock manure, which is a valuable resource in terms of material circulation,
It is considered to be an urgent and important issue for current livestock management.

[0003]

2. Description of the Related Art Heretofore, in this type, the following has been done. Depending on the type of livestock and the feeding management method, its waste treatment is diversified into solid, semi-solid and liquid treatments, and it is seen from simple sedimentation system to industrial composting for slurry system and compost sale. In the case of beef cattle management, it is common to spread solid waste such as sawdust on the beef floor and absorb manure.However, in a free stall type dairy barn, old hay or bark is used to adjust manure water for composting. Various methods have been adopted, such as liquid treatment in the lagoon system.

[0004]

The problems described in the prior art have the following problems. At present, the quality of the treatment system is good, probably because there are some immature parts on the hard side (a series of facilities from deposition / storage to spraying, mechanized equipment) or the soft side (theory and work procedure of manure rot treatment). It seems that compost and slurry are often not produced. As free stall type dairy barns are expected to spread further in the future, it will be necessary to urgently develop and disseminate an inexpensive and labor-saving manure processing system suitable for the same stalls. The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.
