Description

The present invention relates to a method for producing feed and fertilizer from chicken manure .

  Conventionally, many chickens have been bred in poultry farms, and a large amount of chicken manure has been excreted.

  Chicken dung is chicken dung, and because chickens are organisms that digest with phosphoric acid, the feed does not contain salt, and the excreta of chicken dung is rich in nitrogen and potassium in addition to phosphoric acid. Therefore, it is used effectively as a fertilizer (see, for example, Patent Document 1).

JP 2002-160986 A

  However, in the conventional processing method for converting chicken dung into fertilizer, fertilizer is generated using chicken dung as it is as a raw material.

  The chicken manure used as a raw material for this fertilizer contains a large amount of undigested food. Therefore, when the chicken manure is used as a fertilizer as it is, the undigested food is mixed in the fertilizer. Could cause root rot.

Therefore, in the present invention according to claim 1, a feeding process for feeding a chicken and raising it, a chicken droppings collecting process for collecting chicken droppings excreted by the raised chicken, and adding water to the collected chicken droppings to produce a mixture A mixture generating step, a sieve selecting step of screening the generated mixture and selecting a residue remaining on the sieve, liquid water that has passed through the sieve, and a precipitate that has passed through the sieve and precipitated in the moisture; and and feed generating step of generating the feed the residues as raw material, the sorted precipitate and a fertilizer generating step of generating a fertilizer as a raw material, the fertilizer production step, the content of fermentative bacteria and the precipitate After adding the fungus bed to be mixed and fermenting by adding water, the water is evaporated with fermentation heat to generate a compost raw material, and water is added to the compost raw material generated in the compost raw material generating step. Leave still And the solid-liquid separation to have a liquid form compost extraction step of extracting a liquid manure, the manure feedstock produce a solid component separated with the liquid manure by solid-liquid separation in the liquid compost extraction step The present invention provides a method for producing feed and fertilizer from chicken manure, which is used as a fungus bed containing fermentative bacteria in the process .

Further, in the present invention according to claim 2 , in the present invention according to claim 1 , the liquid compost extracted in the liquid compost extraction step is further added with a compost raw material and left to stand for solid-liquid separation. The liquid compost concentration process for concentrating liquid compost was decided.

  And in this invention, there exists an effect described below.

  That is, in the present invention, fertilizer components such as nitrogen, phosphate and potassium contained in chicken manure can be separated and extracted from the undigested material by a sieve selection process, and a fertilizer rich in this fertilizer component is generated. Therefore, chicken manure can be used as a fertilizer and effectively used, and the occurrence of root rot can be prevented even when used as a fertilizer because undigested material is not mixed.

  Further, in the present invention, undigested matter contained in chicken manure can be extracted by the sieve selection step, and feed containing abundant nutrients can be generated using this undigested material as raw material. Can be used effectively.

Since it has a liquid compost extraction process that separates solid and liquid to extract liquid compost by standing, harmful substances such as nematodes can be removed and sprayed to the field when necessary In addition, it is possible to produce liquid compost that effectively removes unripe components from the compost raw material and functions effectively for growing crops.

  Further, the present invention has a liquid compost concentration step of concentrating liquid compost by solid-liquid separation by further adding a compost raw material to the liquid compost extracted in the liquid compost extraction step and allowing to stand. Therefore, the effect as liquid compost can be improved.

  Hereinafter, the chicken farming system according to the present invention will be specifically described with reference to the drawings.

  The poultry farming system according to the present invention treats chicken manure excreted by chickens in the order of breeding step, chicken manure collection step, mixture production step, deodorization step, and sieve selection step, and then feed and fertilizer through the feed production step and fertilizer production step. Is generated. Hereinafter, specific processing in each step will be described (see FIGS. 1 and 2).

[Raising process]
In the breeding process, the chicken is fed with feed in the poultry house 1 for breeding. At this time, as the feed, a new feed is added to the feed generated in the feed generation process described later.

[Chicken manure collection process]
In the chicken manure collection step, the chicken manure excreted from the chicken is collected in one place in the chicken house 1.

[Mixture generation process]
In the mixture production step, water is added to the chicken manure collected in the chicken manure collection step to produce a mixture, and then the mixture is discharged to a discharge pipe. At this time, clean water may be used as the water, but it is also possible to circulate and use the water that is selected and extracted in the sieve selection step described later.

  Here, the chicken manure collection step and the mixture generation step may be performed separately or simultaneously. For example, if poultry manure excreted from chickens in the poultry house 1 is washed away with water into a drain pipe, the poultry man collecting step and the mixture generating step can be performed simultaneously. Even at this time, clean water may be used as the water, but it is also possible to circulate and use the water that is selected and extracted in the sieve selecting step described later. In this way, when the chicken manure is washed with water, the inside of the chicken house 1 can be cleaned, the inside of the chicken house 1 can be cleaned, and the contact between the chicken manure and the air can be cut off to prevent the generation of bad odor. it can.

[Deodorization process]
A deodorizing agent is added to the mixture of chicken manure and water discharged to the discharge pipe in the mixture generation step. Thereby, generation | occurrence | production of a bad odor is prevented completely.

[Screening process]
The sludge-like mixture of chicken manure and water that has undergone the mixture generation step and the deodorization step is poured into the sieve tank 2. The sieve tank 2 has a 1 mm square sieve 4 stretched on the middle upper part of a bottomed cylindrical tank body 3.

  When a mixture of chicken manure and water is poured into the sieve tank 2 and left to stand for one day, the mixture remains as a residue 5 remaining on the upper part of the sieve 4, liquid water 6 that has passed through the sieve 4, and a sieve. 4 is separated (separated) into a precipitate 7 that has passed through 4 and precipitated in moisture.

  This is because the solid undigested material and the muddy digested material (feces) are mixed in the chicken manure, so that the solid undigested material remains as a residue 5 on the upper part of the sieve 4, On the other hand, it is because a muddy digest passes through the sieve 4 and precipitates as a precipitate 7 in moisture.

  Therefore, by screening the mixture of chicken manure and water using the sieve tank 2, the residue 5 mainly composed of undigested material, the water 6 mainly used in the mixture generating step, and mainly from the digested material. The precipitate 7 can be separated well. For example, by screening 300 t of chicken manure, it can be separated into 120 t of residue 5 and 180 t of precipitate 7.

  The residue 5 thus selected in the sieve selection process can be used as a raw material for producing a highly nutritious feed because it contains abundant undigested food. Because it contains abundant acid and potassium, it can be used as a raw material for producing a fertilizer with a high plant-growing effect, and the moisture 6 can be effectively reused as water used in the mixture production process. The amount of water used can be reduced, and the running cost required for processing chicken dung can be reduced.

[Feed production process]
In the feed production process, fermenting bacteria (such as actinomycetes and lactic acid bacteria) are mixed with the residue 5 and fermented. In the initial stage, the fermenting bacteria are directly added to the residue 5, but in the stage of performing the continuous treatment, the fermented bacteria added to the residue 5 and fermented are circulated and used as the fungus bed.

  That is, the fungus bed is put into the silo 8, the fungus bed and the residue 5 are mixed by the mixer 9, and stored in the fermenter 11 in the treatment plant 10. At that time, water is added as necessary so that the water content is about 50% to 60%.

  As a result, the microorganisms contained in the fungus bed start to act by increasing the moisture content, grow with moisture and nutrients contained in the residue 5 as nutrients, and ferment aerobically in the fermenter 11 to produce organic matter. Is disassembled.

  At that time, fermentation heat is generated as the fermentation progresses, and after about 12 hours, the temperature of the microbial bed rises to 70 ° C. or higher enough to make the starchy material into α, and the fermentation is completed after about 14 hours. . As a result, the starch is combined with moisture by the heat of fermentation to produce α starch, and the remaining water that did not contribute to the gelatinization of the starch is evaporated by the heat of fermentation produced during the fermentation. As a result, a solid feed having a moisture content of about 20% to 30% is obtained. This feed is recycled as feed for chickens raised in the breeding process. Thereby, the feed cost which a breeding process requires can be reduced.

  Here, it moves to the fermenter 12 adjacent on the way, after that, it moves to the storage tank 13 as feed which produced | generated one part, and the remainder is moved to the silo 8 as a fungus bed. For example, when 300 tons of chicken manure is processed, 120 tons of residue 5 is produced, and 600 tons of fungus bed is added to this, and 720 tons of the mixture is stored in the fermenter 11 and transferred to the fermenter 12 when it reaches 710 tons. Thereafter, 110 t is used as feed as a final product, and 600 t is recycled as a fungus bed.

  As described above, in the present invention, the undigested product contained in the chicken manure can be extracted by the sieve selection process, and the feed containing the nutrients can be produced using the undigested material as a raw material. Can be used as a feed. In particular, in the feed production process, the residue 5 and fermenting bacteria are mixed and fermented to produce the feed, so that the water contained in the residue 5 is evaporated well by the heat generated by fermentation. Can produce feed with high nutritional value.

  In addition, a residue may be added to the residue 5. For example, solid food waste represented by leftover food or expired foods and liquid food waste with a high water content represented by leftover or expired beverage products were mixed in a blender. Later, the food waste may be crushed in the liquid by a crusher to produce a paste-like food waste, and 5% by weight of starch may be added to the paste-like food waste. The fungus bed contains rice sugar, corn, etc., used for feed and the like with microorganisms having an action of decomposing organic substances such as carbohydrates (for example, actinomycetes, lactic acid bacteria, etc.), and its water content is 10% to 20%. As a percentage, those in which microorganisms are stably stored are preferable.

[Manure production process]
The fertilizer generation process finally generates liquid compost, and is a compost raw material generation process for generating a compost raw material by mixing and fermenting the precipitate 7 and fermentation bacteria, and a compost raw material generation process. Liquid compost extraction process for extracting liquid compost by solid-liquid separation by adding water to the generated compost raw material and allowing to stand, and further compost raw material to the liquid compost extracted by the liquid compost extraction process In addition, it is composed of a liquid compost concentration step that concentrates liquid compost by solid-liquid separation by standing still.

  In the compost raw material production step, fermenting bacteria (such as actinomycetes and lactic acid bacteria) are mixed with the precipitate 7 and fermented. In the initial stage, fermenting bacteria are directly added to the precipitate 7, but in the stage of continuous treatment, the fermented bacteria added to the precipitate 7 and fermented are circulated and used as a fungus bed.

  That is, the fungus bed is put into the silo 14, the fungus bed and the precipitate 7 are mixed by the mixer 15, and stored in the fermenter 17 in the treatment plant 16. At that time, water is added as necessary so that the water content is about 50% to 60%.

  As a result, microorganisms contained in the fungus bed start to act due to an increase in moisture content, grow using moisture and nutrients contained in the precipitate 7 as nutrients, and ferment aerobically in the fermenter 17 to produce organic matter. Is disassembled.

  At that time, fermentation heat is generated as the fermentation progresses, and after about 12 hours, the temperature of the microbial bed rises to 70 ° C. or higher enough to make the starchy material into α, and the fermentation is completed after about 14 hours. . As a result, the starch is combined with moisture by the heat of fermentation to produce α starch, and the remaining water that did not contribute to the gelatinization of the starch is evaporated by the heat of fermentation produced during the fermentation. As a result, it becomes a solid compost raw material having a moisture content of about 20% to 30%.

  Here, it moves to the fermenter 18 adjacent on the way, and then it moves to the storage tank 19 as a compost raw material which produced | generated one part, and the remainder is moved to the silo 14 as a fungus bed. For example, when 300 t of chicken manure is processed, 180 t of precipitate 7 is produced, 900 t of fungus bed is added to this, 1080 t of the mixture is stored in the fermenter 17, and transferred to the fermenter 18 when it reaches 1060 t. Thereafter, 160 t is used as a compost raw material as a final product, and 900 t is recycled as a fungus bed.

  A sediment may be added to the precipitate 7. For example, solid food waste represented by leftover food or expired foods and liquid food waste with a high water content represented by leftover or expired beverage products were mixed in a blender. Later, the food waste may be crushed in the liquid by a crusher to produce a paste-like food waste, and 5% by weight of starch may be added to the paste-like food waste. The fungus bed contains rice sugar, corn, etc., used for feed and the like with microorganisms having an action of decomposing organic substances such as carbohydrates (for example, actinomycetes, lactic acid bacteria, etc.), and its water content is 10% to 20%. As a percentage, those in which microorganisms are stably stored are preferable.

  Next, in the liquid compost extraction process, it is transferred from the storage tank 19 to the processing tank 20, and inside the processing tank 20, about 8 times by weight of water is added to the compost raw material produced in the compost raw material production process and stirred and mixed. And then let stand for about 24 hours. Thereby, solid content precipitates in the bottom part of the processing tank 20, and is solid-liquid-separated into a supernatant liquid and a deposit. Then, only the supernatant liquid of the processing tank 20 is extracted as liquid compost and transferred to the storage tank 21.

  In this way, by adding water to the compost raw material and extracting liquid compost, harmful substances such as nematodes contained in the solid compost raw material can be removed, and unripe components in the compost raw material can be removed. Can be removed.

  This liquid compost can be used as it is as a liquid compost. Moreover, since the precipitate contains fermenting bacteria, it can be reused as a fungus bed, or can be effectively used as feed.

  Next, in the liquid compost concentrating step, in the treatment tank 20, the compost raw material generated in the compost raw material generating step of about 1/8 times the weight ratio is further added to the liquid compost extracted in the liquid compost extracting step, Add water if necessary, mix with stirring and let stand for about 24 hours. Thereby, solid content precipitates in the bottom part of the processing tank 20, and is solid-liquid-separated into a supernatant liquid and a deposit. Then, only the supernatant liquid of the processing tank 20 is extracted as liquid compost and transferred to the storage tank 21.

  By applying this liquid compost concentration step, the active ingredient contained in the liquid compost is concentrated.

  Thus, liquid compost can be manufactured by a fertilizer production process. When the effectiveness of this liquid compost was tested, it was confirmed that the cultivation of the crop was promoted more than when it was grown without using any compost. In addition, it was confirmed that when growing using compost raw materials, the growth of crops was suppressed more than when no compost was used. From this, it was confirmed that the liquid compost extraction process for extracting liquid compost from the compost raw material successfully removed the unripe components in the compost raw material and improved the efficacy as liquid compost.

  As described above, in the present invention, fertilizers such as nitrogen, phosphoric acid and potassium contained in chicken manure can be separated and extracted from the undigested material by the sieve selection process, and fertilizers rich in this fertilizer component Can be effectively used by fertilizing chicken manure, and since undigested materials are not mixed, the occurrence of root rot can be prevented even when used as a fertilizer.

  Further, in the present invention, liquid compost is produced by extracting liquid compost from compost raw materials, so that harmful substances such as nematodes can be removed and sprayed to the field when necessary. In addition, it is possible to produce liquid compost that effectively removes unripe components in the compost raw material and functions effectively for crop cultivation.

  Moreover, the effect as compost can be improved by concentrating liquid compost, and the labor and expense which are required for conveyance of undiluted | stock solution can be reduced by using it diluted.
