Abstract

Process and apparatus for processing fowl droppings into feed by lactic fermentation, without developing abnormal fermentation, i.e., by effecting the fermentation over a plurality of stages from aerobic fermentation through up to anaerobic fermentation, to obtain a composite lactic fermentation product of good quality. When fowl droppings are subjected to lactic fermentation by adding alcohol waste liquor, acetic acid, and the like thereto, and by further adding a fermentation starter, fermentation does not proceed smoothly and non-uniform fermentation takes place locally. Moreover, only anaerobic fermentation proceeds, resulting in variations in the quality of the final product, reduced fragrance, and a less desirable flavor for livestock. In this invention, fowl droppings are pulverized into fine particles by a high-speed rotary mixer, and are dispersed while being admixed with the air, to promote lactic fermentation. According to the invention, therefore, the fowl droppings are not agglomerated as in the conventional art; fermentation proceeds homogeneously with no malfunctions. Furthermore, composite lactic fermentation product of good quality is obtained through the lactic fermentation of three stages, i.e., aerobic fermentation - facultative anaerobic fermentation - anaerobic fermentation, having a good fragrance and flavor for the livestock.

Description

Specification

Title of the invention Method and apparatus for converting chicken dung into feed

Technical field

The present invention relates to a method and an apparatus for converting poultry manure into feed and, more particularly, to produce lactic acid fermentation uniformly without abnormal fermentation of poultry manure, thereby forming a high-quality lactic acid fermentation product. The present invention relates to a method and an apparatus for converting poultry manure into feed which is excellent in feed rate or feed intermediate.

Background art

A large amount of the active ingredient as feed remains in chicken dung. This is because chickens are a kind of birds, and birds fly in the air. This is due to the general physiology of birds in releasing, which is highly nutritious t ', takes food, rapidly absorbs the most easily absorbed parts, and leaves many unabsorbed parts This is because they are excreted as feces. In addition, at this time, metabolites such as sandbags, stomach, and intestines, and digestive juices from each digestive tract are mixed together and excreted. Therefore, the excrement of chickens is extremely nutritious and very easily absorbed. Therefore, it is extremely useful to reuse it as feed.

For these reasons, various attempts have been made to convert chicken manure into feed. However, most attempts have been made to convert to dry feed, and the foul odor generated during the drying process of chicken manures caused pollution problems. Poultry manure value is not being used effectively

As a solution to the above problem, Japanese Patent No. 963175 There is a method of converting chicken dung into feed.

The method is as follows. First, poultry manure and alcohol waste liquid are put into a mixer, mixed by a mixer to form a muddy state, and then acetic acid is added to adjust the pH to about 6.1, and the temperature is adjusted to about 60 at about 60 ° C. Warm to kill various germs. Next, starches such as rice sugar and barley are added as fermentation aids, the temperature is reduced to 32'c, a small amount of alcohol is added, and anaerobic lactic acid fermentation is carried out with gentle stirring. It is converted into a liquid feed with aroma.

According to this method, no malodor was generated, and the resulting feed was liquid-digested, so that digestion was easy and the beef cattle bred using this was ranked at the highest quality. It also has the advantage of being inexpensive.

However, it was found that the above method had the following problems.

In other words, when large-scale processing was attempted by increasing the size of the equipment using the above-mentioned method, abnormal kishi-yaki gradually occurred during the kaki-yaki process, and the quality of the final product fluctuated. Some problems were pointed out. In addition, it was pointed out that the abnormal fermentation caused a problem that the fragrance was low, the palatability of the cow was lowered, the appetite was reduced, and the growth was delayed.

The inventor of the present invention has earnestly studied to eliminate the above-mentioned problems, and as a result, has obtained the following findings, thereby completing the present invention.

That is, first, it was found that the abnormal fermentation occurs when the chicken manure and the alcohol waste liquid are mixed, and the chicken manure is not sufficiently crushed and remains coarse or small. Poultry manure has a high solid content, and is partially dried and solidified when collected from a poultry farm. If it is moderate, it will not be sufficiently crushed and will remain coarse or aggregated. If the chicken manure remains coarse or aggregated in this way, even if the environmental conditions such as pH and temperature are adjusted to the conditions suitable for lactic acid fermentation, the conditions suitable for lactic acid fermentation if the inside of the coarse particles or aggregates are maintained. Instead, the nucleus led to abnormal fermentation in which various bacteria gradually propagated to the surroundings.

Therefore, the present inventor has obtained the knowledge that at least chicken dung should be finely divided and homogenized by a high-speed rotation mixer. In addition, when micronizing with a high-speed rotating mixer, microbubbles of air are simultaneously entrained in the mixture with the alcohol waste liquid, etc., and are dispersed and maintained in the mixture. Then, as oxygen was consumed, it was found that lactic acid bacteria grew in three stages: facultatively anaerobic and then anaerobic. ·

Furthermore, it was also found that waste blood and digestive organ undigested residues of 4 cattle-killed pigs, which had been discarded in the past, can be mixed with poultry manure, etc., and made into a suitable feed.

BRIEF DESCRIPTION OF THE FIGURES

The drawing is an explanatory view showing a chicken manure feed converting apparatus. '' Best mode for carrying out the invention

In the method of the present invention, first, a mixture of chicken dung, alcohol waste liquid (or molasses), which is a main raw material, and a fermentation aid is weakly acidified with acetic acid, and the temperature is also adjusted to about 40'c, and the high-speed rotation is performed. Pulverize the mixture with a mixer so that it becomes fine particles, and knead. When kneading with this high-speed mixer, air is simultaneously entrained and dispersed in the mixture as microbubbles.

The mixing of the air may be performed by blowing air into the mixture with an appropriate pipe or the like.

The heating of the raw materials in the high-speed mixer may be performed by means of electric heating or the like, but the easiest method is to put in an appropriate amount of heat, which can be performed quickly and the temperature can be adjusted. It is flexible and convenient.

The heating condition is suitably around 40'c, but may be in the temperature range of 30 ° C to 65 ° C, that is, in the range of lactic acid bacteria inhabiting temperature. In addition, PH is adjusted by acetic acid to a weak acidity (about pH 5 to 6), which is the range of lactic acid bacteria. .

This pH can be adjusted with citrate or other organic acids, but acetic acid is the most preferred for preventing spoilage.

The kishi is transferred to an aging tank.

In the early stage of the kishi, the temperature, PH, and uric acid in chicken dung Under these conditions, aerobic lactic acid bacteria grow for a while. In order to promote the propagation of this aerobic bacterium, it is necessary that the chicken dung be finely crushed, and that the air be properly supplied and dispersed.

If the poultry manure is not sufficiently converted into fine particles and coarse particles or aggregates remain, the inside of the coarse particles or aggregates does not become a lactic acid bacteria propagation environment as described above, causing abnormal fermentation. In addition, aerobic bacteria do not propagate unless appropriate air is mixed. <In the present invention, chicken dung is finely divided into colloid particle dogs and homogenized by a high-speed rotating mixer. As a result, uniform lactate fermentation is promoted, and at the same time, an appropriate amount of air is dispersed in the mixture in the form of microbubbles, thereby enabling aerobic fermentation.

As aerobic bacteria proliferate and the air decreases, the environment suitable for the propagation of facultative anaerobic lactic acid bacteria then develops, further consuming more air Finally, an environment suitable for the propagation of anaerobic lactic acid bacteria will be established, and the most powerful bacterium of the anaerobic lactic acid bacteria will be established.

In a series of lactic acid bacteria breeding processes from aerobic to anaerobic as described above, various lactic acid bacteria propagate and alternate, thereby producing various complex lactic acids. As a result, it is possible to obtain a feed that is aromatic and has a very good taste for livestock.

In other words, in the present invention, aerobic-facultative anaerobic from aerobic to anaerobic to three-stage anaerobic growth of lactic acid bacteria, and from a relatively high temperature (around UO'c) to normal temperature To actively promote various lactic acid bacteria over a wide temperature range, that is, from high temperature to cooling to room temperature, and to make the best use of all the given conditions Various kinds of lactic acid It produces more yeast products. In the above series of processes, various sugars and fibers in various materials are decomposed and converted to lactic acid, but this is done not by a single type of bacteria but by multiple types of bacteria Therefore, it can be made more diverse and efficient. In addition, the proliferation of various useful lactic acid bacteria kills various germs and suppresses abnormal fermentation.

In the present invention, chicken dung is used as the main raw material, and waste blood from beef-killing pigs, undigested residues of digestive organs thereof, or both are added in appropriate amounts. be able to. In addition to these, X also undergoes the same fermentation process as above, namely, aerobic ~ → facultative anaerobic ~ → anaerobic three-stage fermentation proceeds, and contains a large amount of various lactic acid fermentation products A highly aromatic feed with very good taste for livestock can be obtained. It should be noted that waste blood is liable to clump due to its coagulation action, and if used as it is, abnormal fermentation will still occur. However, by using a high-speed rotating mixer together with chicken dung, abnormal koji fermentation is suppressed.

Alcohol waste (alcohol pomace) or molasses (alcohol raw material) may be used alone or in combination. These mainly act as accelerators for lactic acid fermentation.

The fermentation aid is a nutrient source for lactic acid bacteria. Examples of the mashing aid include cereals such as barley, by-products of cereal grains such as rice bran, and oil cakes such as coconut oil and mirin. These may be used alone or in combination.

Although not shown, it has stirring blades, and air is entrapped to make it fine and micro bubbles And mixed into the mixture. If necessary, an air blowing pipe may be provided to blow air into the mixture.

12.1.2 is a device for supplying raw materials, which is equipped with a pump, a valve mechanism, a supply pipe, and the like, and supplies raw materials into the high-speed rotating mixer 10. Necessary numbers of chicken feces, alcohol waste, acetic acid, fermentation aid, etc. are arranged.

Reference numeral 14 denotes a hot water supply device, which comprises a boiler or the like, and supplies hot water into the high-speed rotation mixer 10.

Reference numeral 16 denotes an aging tank, which performs a three-stage lactic acid fermentation of the mixture prepared in the high-speed rotating mixer 10 to aerobic—facultative anaerobic ”^ anaerobic.

Examples will be described below.

Example 1. Poultry manure, alcohol waste liquid or molasses, and various fermentation aids such as cereals and agricultural products are put into a relatively small high-speed mixer as appropriate. The mixture is adjusted to a weak acidity, quickly heated to a temperature of about 40'c, and kneaded at 1200 rpm for about 1 to 2 minutes.

Poultry manure and other ingredients are also broken up and mixed into fine particles.

At the same time, during high-speed rotation, the air is also entrained, is broken up into small bubbles, disperses, and mixes with the boar.

This is allowed to flow down into the maturation tank, and the above operation is repeated several times.When a certain amount has accumulated in the maturation tank, it is released in the maturation tank at intervals of about 2 hours for about 15 to 20 minutes. Stir for about 10 hours (1 晚). During this time, the complex lactic acid fermentation proceeds while a large amount of cocci living in the chicken dung are rapidly transformed into lactobacilli under the given conditions such as pH and PH, and aromatic lactic acid fermentation products are produced. . This is chicken The dung feed is completed.

Example 2

Poultry manure, alcohol waste liquor or molasses, and various fermentation aids such as grains and agricultural products are appropriately added to a relatively small high-speed tillage mixer, and the pH is adjusted to weakly acidic with acetic acid. , About 90. Add the boiling water of c, quickly warm to a temperature of about 40'c, and knead at a high speed (1200 rpm) for 1-2 minutes.

At the same time, during high-speed rotation, air is also entrained, broken into small bubbles, dispersed, and mixed together.

This is allowed to flow down into the maturation tank, and the above operation is repeated several times.A certain amount of water is accumulated in the maturation tank at an interval of about 2 hours. Stir and stir for about 10 hours (1 晚). During this time, a large amount of cocci in chicken dung rapidly change to lactobacilli under the given temperature, temperature, etc. During this process, complex lactic acid fermentation proceeds to produce aromatic lactic acid fermentation products, which completes the conversion of chicken manure to feed.

Example 3

And the undigested residue remaining in the cattle-killing blood and digestive organs, chicken manure, alcohol waste liquid (or molasses), and various fermentation aids such as grains and agricultural products. placed in a high speed mini key support one small, the ΡΉ with acetic acid adjusted to weakly acidic, about 40 'C promptly warmed to a temperature around the addition of hot water of approximately 90 hand, at a rotational speed 1200R _{P in} about

Knead for 1-2 minutes.

Undigested residue, poultry manure and other ingredients are also broken up and mixed into fine particles.

At the same time, during high-speed tillage, air is also caught in ,

It is broken up into bubbles and dispersed, and mixed together.

This is allowed to flow down into the maturation tank, and the above operation is repeated several times. When a certain amount has accumulated in the maturation tank, it is removed in the maturation tank at intervals of about 2 hours for about 15 to 20 minutes. Stir for about 10 hours (overnight). During this time, complex lactic acid fermentation by the lactic acid bacteria that inhabits progresses, and an aromatic lactic acid fermentation product is produced. This completes the refeeding of the waste blood and undigested residue and the chicken manure mixed simultaneously.

When the feed obtained by the above treatment is actually used, it is necessary to add an appropriate amount of fiber such as hay or rice porridge (preferably lime) for each animal species, for example, cattle. In the case of pigs, adjust the nutritional balance according to the species of livestock by adding some starch, cereals, etc. depending on the stage of development.

In addition, by mixing this feed with various kinds of kaguri varieties with palatability, the palatability is improved, and it becomes possible to eat it.

In addition, due to the completion of ripening, the fungus in the feed is stabilized, and does not deteriorate for a long period, and can be stored as it is.

As described above, according to the present invention, chicken litter is uniformly fermented without abnormal fermentation of chicken dung, and is formed into a high-quality complex lactate knapsack product, which improves nutritional value, digestibility, and palatability. It has a remarkable effect that it can be used as a clean feed or a feed intermediate.

In the above series of processes, various sugars and fibers in the above-mentioned materials are tanned and converted to lactic acid, but this is not a single kind of bacteria but a plurality of bacteria. To do so, it is done more and more efficiently. In this process, there is almost no room for fungi to survive. The series of breeding processes described above also serves as a sterilizer. Industrial applicability

The feed obtained by the present invention is suitably used for cattle, pigs and other livestock.
