Description

[Detailed Description of the Invention] (Industrial Application Field) The invention is directed to waste slurry containing a large amount of water, which is left behind after fermented alcohol-containing slurry is collected during the brewing of shochu to obtain a shochu stock solution. Compound feed for livestock obtained by mixing with other water-absorbing materials relates to its main constituent raw materials and its manufacturing method.

More specifically, uninvented products are generated in large quantities as waste during the brewing process.12) Moisture is 90% or more, and
, Since υV water cannot be produced as it is due to the high COD load, waste slurry, which is a serious problem in terms of waste treatment, is processed and livestock jT! By using it as a mixed feed or one of its basic raw materials, it is possible to simultaneously solve the problem of waste slurry disposal, which is a problem in shochu brewing, and the problem of domestic supply of raw materials for livestock feed. This invention relates to a possible compounded feed and its manufacturing method.

(Prior art) There are a large number of alcoholic beverages on the market, but the demand for shochu is increasing in recent years, and the demand for shochu in Japan is particularly high. There is something.

Distilled liquors with a high alcohol content such as shochu contain less polyhydric alcohol, which creates richness, bitterness, and umami, than brewed liquors such as sake and finn, and ingredients that have a negative effect on health. Because it is rare, cheap, and suitable as a base for various turnip tails, it is loved by young people, and it has also become popular as a pseudonym for middle and high school students. Status! It's a bar. At the time, yam was mainly used as the raw material, but in recent years shochu is now mostly brewed using yam rind as the raw material, as cheap so-called yam rind from foreign countries can be imported regardless of the season and at low cost. Shochu is produced in each prefecture of Kyushu as T. However, taking Kagoshima Prefecture, which is famous for its specialty, as an example, it is shipped in barrels to other prefectures, and the waste slurry generated during distillation is sold annually. It has reached 250,000 tons.

Moreover, this waste slurry has a high BOD and COD loading rate and cannot be discharged as it is, so it is actually disposed of by ocean dumping.

(Problem to be solved by the invention) Instead of dumping the waste into the ocean, which requires transportation costs and is also unethical from the point of view of environmental conservation, it can be contained in slurry and become a BOD. .

It is clear that it would be extremely effective to solve the problem if we could establish a product that effectively utilizes protein, which is the source of COD, and its manufacturing method, but there are many problems that need to be solved.

Although this slurry is a solid-liquid mixture, it is suitable for synthesizing feed for pigs and general livestock because it contains a large amount of nutritional components such as protein. I understand.

- - Since this slurry has a moisture content of over 90%, in order to use it as a raw material for livestock feed, the water must be adsorbed onto another solid material with a high water absorption rate to reduce the overall moisture content to 40%.
For pig farming, it is essential to reduce the amount to 20% or less.

Such adsorption solid materials have a high ability to adsorb moisture in waste slurry, and are also suitable for the taste of home iVR as raw materials for livestock feed, and are inexpensive and have a high ability to enter the market. The substance must also be suitable in terms of composition.

(Means for Solving the Problem) As a result of the inventor's investigation into a substance that adsorbs moisture in waste slurry and satisfies the above conditions, the inventor selected sawdust obtained from sawn timber and thinned wood, and determined which type of material to crush. things were considered appropriate. However, these materials still contain Hh fibers, and the lignin in the fibers causes indigestion in livestock and other animals, making them unsuitable for feed. The first priority is to decompose large amounts of lignin in an economical manner.

In terms of obtaining these adsorbent materials, it is currently difficult to manually produce large amounts of sawnwood flour, so as an alternative to this, thinning, which occurs in large quantities as a security measure for tree plantations, is recommended. It turned out that it would be best to guard the area using a saw-making machine made of wood. Sugar cane husks, rice husks, and dried Maki Q are also useful targets.

As a method for disintegrating the lignin in these raw materials 1,
These powders are adiabatically compressed to a temperature of about 250'C1.
When the lignin structure is decomposed and the lignin structure is exposed to fire after the shochu brewing process, a dry powder with a rough base content of 20% or less is produced. is more than 90% -L and Kitakami is about 1.03, and when left still, it divides into three layers, the highest layer being mostly wastewater and the second and third layers being waste mud.

Therefore, it is necessary to carry out experiments including preliminary tests to determine in what proportion each layer should be mixed with the adsorbent and treated.

(Preliminary Experiment) 1F1) As already mentioned, when waste shochu slurry is put into a beer bottle and left to stand, it separates into three layers as shown in Figure 2. As raw materials for feed, it is preferable to separate the first layer, which is the upper layer containing many active ingredients, into a mechanical mixer using a centrifugal divider, etc., but the third layer, which is the top layer, contains the above-mentioned Not only is the BOD load high and wastewater treatment is essential after solid-liquid separation, but also the protein is present in a soluble form during the shochu process, making it an active ingredient in the third layer from the standpoint of livestock feed. It is also desirable to make effective use of Therefore, a stock solution of 3yF9, a solution obtained by stirring and selling this stock solution to promote oxidation, and a mixed solution of the second and third layers (
Table 1 shows the results of measuring the BOD and pH values of four samples: a filtrate in which 1: L) 100 cG and 10 gr I7) 11 crushed rice flour were mixed, and the 11 filtration residue.

Note: NO,l and N004 are the same sample in the third layer, and N09
In No. 1, oxidation was promoted by stirring, and it can be seen that when oxidation is performed during the manufacturing process, the BOD load is reduced due to aerobic fermentation, etc.

The NO12 results show that the components dissolved in the filtrate escape into the filtrate, and the jliIiS residual liquid has an extremely high B
OD load, while for such waste slurry 72
The physical properties of the blasted sawdust to be combined are as follows.

Moisture content: 20% or less Uniform particle size: 20 microns The glue-m structure in the fiber is almost decomposed ff:
.

From this point of view, if blasted sawdust is used as a water absorbing agent, it will not only adsorb dissolved proteins in the waste slurry, but also
It has the effect of helping livestock with digestion and intestinal regulation.

Note that 1. Since the water content of the slurry is high, if a large amount of blasted sawdust is added, the water content of the blended product will be lowered, but the active ingredient as a synthetic feed will be relatively reduced.

Taking these points into consideration, a preliminary test was conducted to determine the blending ratio based on Table 2 below.

(=p 9k v-) From the above results, the solid-liquid content of the blended product is too high and uniform mixing is completely impossible, and the target water content for feed synthesis is 20%, preferably 15%. In order to achieve this, it is necessary to further increase the blending ratio of crushed rice flour as mentioned above, but since mixing becomes increasingly difficult and the protein content decreases, we have no choice but to use the following third method. Followed the recipe in the table.

Note: The above waste mud is slurry No. 12 in Table 2 and:
It is a mixture of three layers of i'S.

This synthetic product (goods) III! Table 4 shows the analysis results of the active ingredients by the Japan Food Inspection Association.

From the results in Table 4, the carbohydrate content is as shown in Table 5. Based on the results north of this point, we decided to adopt No. 4 in Table 4. Extracted from Table 4 in terms of dry matter: Crude protein...14,59$ Crude fat...3,45% Fiber...44,49% Crude ash...1,31% Soluble nitrogen-free 38.14%.

From the above results, it was found that the flowchart shown in FIG. 1 should be used as the manufacturing method.

(Effects) Attempts were made to synthesize a similar feed using sawdust as is, but the animal's vocalizations were poor and the method was deemed unsuitable.

In the composite product of the present invention, the m-fibers of sawdust are also produced by adiabatic compression.
It is decomposed and pulverized by raising the temperature to 50'C, has a woody aroma and has good taste, and the active ingredients are within the acceptable range for pig farming, so the above-mentioned blasting powder is suitable for dairy farming. is M% −+ 41 people 11 −
