しかし、竹材から製造される竹堆肥は、作物の栽培に必要な肥料成分、特に窒素が少ない。
また、竹堆肥を作るための原料となる竹材には水分が少なく、堆肥化するためには多量の水を加える必要がある。
一方で、茶飲料の製造過程で生じる茶殻は窒素及び水を多く含むため、茶殻のみで堆肥を製造する場合には、堆肥化過程で腐敗する問題がある。
そこで、茶殻のみで堆肥を製造するには、適切な水分状態まで乾燥させる過程が必要となる。
However, bamboo compost produced from bamboo has less fertilizer components, especially nitrogen, necessary for crop cultivation.
In addition, the bamboo material, which is a raw material for making bamboo compost, has little water, and it is necessary to add a large amount of water to make it compost.
On the other hand, since the tea husk produced in the production process of tea beverages contains a large amount of nitrogen and water, when compost is produced only from the tea husk, there is a problem that it rots during the composting process.
Therefore, in order to produce compost using only tea husks, a process of drying to an appropriate moisture state is required.
本発明は、腐敗に至ることなく迅速に高い窒素成分の堆肥を製造できる竹材及び茶殻の堆肥化方法を提供することを目的とする。 The present invention aims to provide a composting how the bamboo and used tea leaves that can produce compost quickly high nitrogen content without leading to spoilage.

Bamboo compost continues to decline gradually and composting continues moderately even after 100 days have passed since composting started. On the other hand, bamboo tea compost (2 to 3) and bamboo tea compost (1 to 4) have stable nitrogen content and carbon content after 40 days after composting, and composting is completed in about 40 days. ing. Furthermore, bamboo tea compost (1: 4) had a higher nitrogen content than bamboo tea compost (2: 3), and became bamboo tea compost containing a large amount of nitrogen components.

FIG. 3 is a flowchart illustrating a method for composting bamboo and tea leaves according to an embodiment of the present invention.
First, a defibrated bamboo fiber chopped strand is produced.
As the bamboo material, for example, Sousaku bamboo, Japanese bamboo, or bamboo bamboo is used.
As step 1, the harvested bamboo material such as 孟 宗 bamboo, Japanese bamboo, or bamboo shoot is crushed into required small pieces of about 20 cm to 50 cm.
A small amount of bamboo crushed in the crushing process in Step 1 is mixed with tea husk having a moisture content of 70% or more (Step 2).
The bamboo material and tea husk mixed in the tea husk mixing step in step 2 are pressure-kneaded by a pressure extrusion device at least at an internal pressure of 15 kg / cm 2 or more (step 3). A screw can be used for kneading.
Since the hardness varies depending on the type of bamboo material, it is preferable to adjust the internal pressure depending on the type of bamboo. For example, in Sasatake, at least 15 Kg / cm 2 or more, the bamboo and 30Kg / cm 2 ~50Kg / cm 2 .
The tea husk and bamboo material pressure-kneaded in the pressure-kneading step in step 3 are cut into a length of 20 mm to 200 mm by a cutter, minced, and discharged into the atmosphere from a porous nozzle (step 4).
The bamboo material is disassembled into a hard tissue and a soft tissue by the swelling diffusion process in Step 4, and a defibrated bamboo fiber chopped strand in which cellulose and hemicellulose that form cell walls are dissociated from lignin can be obtained.
The defibrated bamboo fiber chopped strands obtained by the swelling diffusion process are mixed with the tea husk. Moreover, the ratio of the size of this bamboo fiber chopped strand is 73% for 3 mm or less, 17% for 3 mm to 5 mm, 5% for 5 mm to 7 mm, and 5% for 7 mm or more.

ステップ5における堆肥化工程では、水分率が60〜75%程度、好ましくは70%程度を維持するように、適宜水分を与えるとともに、混合切り返しを行う。冬季のように雰囲気温度の低い時期は、竹繊維チョップドストランドをビニールシートで覆うことで70℃程度の発酵熱を維持することが好ましい。堆肥化工程は、前述の通り40日程度である。
The bamboo fiber chopped strands discharged by the swelling diffusion process in step 4 and mixed with the tea husk are composted for a predetermined period (step 5).
Bamboo fiber chopped strands discharged by the swelling diffusion process and mixed with tea husks have a moisture content of 64% to 75%, and lactic acid bacteria inhabit the bamboo fiber chopped strands themselves. It becomes.
In the composting process in Step 5, the water content is appropriately given so that the water content is maintained at about 60 to 75%, and preferably about 70%, and mixed turning is performed. It is preferable to maintain the fermentation heat of about 70 ° C. by covering the bamboo fiber chopped strand with a vinyl sheet at a time when the ambient temperature is low as in winter. The composting process is about 40 days as described above.
以上のように本実施例によれば、破砕工程で破砕した竹材に、含水率が70%以上の茶殻を混合し、混合した竹材と茶殻とを加圧混練し、加圧混練した茶殻及び竹材をカッターで裁断してミンチ状にし、茶殻が混合された解繊状の竹繊維チョップドストランドを堆肥化処理することで、竹材と茶殻とをそれぞれ単独で堆肥化する場合と比較して、腐敗に至ることなく迅速に高い窒素成分の堆肥を製造できる。
また、本実施例によれば、茶殻混合工程で混合する茶殻を、水分を含む重量比で、竹材に対して1.5倍〜4倍とすることで、竹材を単独で肥料化する場合と比較して堆肥化期間を短縮できる。
また、本実施例によれば、膨潤拡散工程で吐出される、茶殻と竹繊維チョップドストランドとの混合物の含水率が64%〜75%となるように、茶殻混合工程で茶殻を混合することで、堆肥化に最適な水分含量とすることができる。
また、本実施例による堆肥は、茶殻と竹繊維チョップドストランドとを主原料とすることで堆肥化を容易に行えるとともに、肥料効果の高い堆肥を得ることができる。
また、本実施例によれば、堆肥化工程の後に製造される堆肥は、全窒素含有量が1%以上となるように茶殻を混合することで、肥料効果の高い堆肥を得ることができる。
As described above, according to the present embodiment, the bamboo material crushed in the crushing step is mixed with tea husk having a moisture content of 70% or more, the mixed bamboo material and tea husk are pressure-kneaded, and the pressure-kneaded tea husk and bamboo material. Is cut into a minced shape with a cutter, and the chopped strands of defibrated bamboo fiber mixed with tea husks are composted. A compost with a high nitrogen content can be produced quickly without going through.
In addition, according to the present embodiment, the tea husk mixed in the tea husk mixing step is made into a fertilizer by making the bamboo alone by making the weight ratio including water 1.5 to 4 times the bamboo. The composting period can be shortened in comparison.
Moreover, according to the present Example, by mixing the tea husks in the tea husk mixing step so that the water content of the mixture of the tea husks and bamboo fiber chopped strands discharged in the swelling diffusion step is 64% to 75%. The water content can be optimized for composting.
In addition, the compost according to the present embodiment can be easily composted using tea husk and bamboo fiber chopped strands as main raw materials, and compost having a high fertilizer effect can be obtained.
Further, by the present embodiment lever, compost that will be produced after the composting process, by total nitrogen content of mixed tea leaves to be 1% or more, it is possible to obtain a high fertilizer effect compost .
