2. Description of the Related Art Some of the shochu lees produced in the shochu manufacturing process are used as livestock feed, either as an undiluted solution or after being concentrated and dried. However, most of them have been dumped into the ocean, returned to the earth, incinerated, or treated by living organisms. It has been disposed of by biological treatment. However, under the circumstances where global environmental measures are required in recent years, ocean dumping, which is currently the most dependable method for disposing of shochu lees, is legally regulated and totally prohibited. There is a problem such as polluting. Incineration has problems in terms of cost, and the BOD of shochu is 70,000 to 100,000 m for biological treatment.
Since it is extremely high at g / l, it is very difficult to perform aptitude treatment. Therefore, in recent years, effective use of shochu lees as feed for livestock has been renewed attention in place of these disposals.

As a method for producing livestock feed and the like for effective use of this shochu lees, koji mold is added to the shochu lees (Japanese Patent Laid-Open No. 64-20090) or Chlorella (Japanese Patent Laid-Open No. 64-9090). 39950), a method of mixing with starchy food waste (Japanese Patent Laid-Open No. 58-49148) and the like, but all of them contain a large amount of impurities and have low water content and high protein content made from pure shochu lees. It was difficult to obtain a highly-preservable feed for

On the other hand, a technique for solid-liquid-separating shochu lees to reduce water content and then drying the solid matter to form a feed is disclosed in Japanese Patent Laid-Open No. HEI-1.
It is publicly known as 196286 and the like. For solid-liquid separation of shochu lees, a method of discharging lees into a drum to separate solids inside and liquid outside (JP-A-48-87472), and filtration dehydration using a gelling agent such as sodium alginate Method (JP-A-56
-51978) and the like, the separation by the drum inevitably has a problem of leaking the solid to the liquid side, and the gelling agent also has a problem of high cost.

In the method of heating and concentrating as known from Japanese Examined Patent Publication No. 57-3431, since the stock solution is concentrated as it is, the concentration rate is limited due to clogging of the pump and the like, and charring occurs when it is dried with a drum dryer or the like. There is a problem that the product value does not increase.

[0006]

As described above, it was difficult to obtain a feed having a low water content and a high protein preservability by the conventional method for producing a feed from shochu lees, but this problem This is a problem that has to be solved promptly in order to promote the effective use of shochu lees as livestock feed in consideration of environmental measures.

The present invention has been completed as a result of further research based on the above-mentioned findings, and the main object of the present invention is to solve the above-mentioned problems associated with the conventional production of feed from shochu lees and preserve it. An object of the present invention is to provide a method for producing a feed obtained from shochu lees, which has excellent properties and palatability.

[0008]

[Means for Solving the Problems] The present inventors have solved the above-mentioned problems in the production of feed from conventional shochu lees, and from the viewpoint of effective utilization and recycling of shochu lees, by improving the feed production method, In order to obtain a commercial feed excellent in shelf life and palatability, intensive research was conducted through experiments. As a result, the shochu lees are separated into solid and liquid, dried separately to a predetermined water content, and then mixed at a mixing ratio of a certain value or more
This is a finding that a feed for livestock having a low water content, a high protein preservation property and an excellent palatability can be obtained, and the above technical problems can be solved.

Specifically, the essence of the method for producing a feed obtained from the shochu lees of the present invention that achieves the above-mentioned object is to solid-liquid separate the shochu lees and dry the liquid and solid components separately to a predetermined water content. After that, both are mixed at a mixing ratio of a certain value or more.

More specifically, the method for producing a feed obtained from shochu lees according to the first aspect of the present invention separates the shochu lees obtained in the distillation step into a liquid component and a solid component, After adjusting to 100 (g / l) or less, the liquid content and the solid content are dried by separate dryers, respectively, and then the liquid content dried material and the solid content dried material are mixed. Here, the suspended matter means, of the liquid content and solid content obtained by solid-liquid separation of the shochu lees obtained in the distillation step of the shochu production , the insoluble which is not dissolved in the liquid content and is dispersed.
Refers to sexual substances. In the following, this suspended material (Suspended
solid) is called SS.

The method of producing a feed obtained from shochu lees according to the third aspect of the present invention is characterized in that the mixing ratio of the solid dry matter to the liquid dry matter is 10: 1 or more.

[0012]

In the first aspect of the invention, it is necessary to adjust the SS of the liquid component obtained by solid-liquid separation of shochu lees to 100 (g / l) or less. Table 1 shows SS before drying in the liquid content and product evaluation. In the experiment, SS is 110 to 80 (g /
The raw materials prepared in 1) were dried by a disk dryer until no charring occurred, and the product states were compared.

[0013]

[Table 1] As can be seen from Table 1, SS before drying is 100 (g /
If it is 1) or less, heat exchange is efficiently performed and the water content after drying becomes 11% or less, and the water condition as the feed for distribution (12% or less in the summer, 13% or less in the winter) is satisfied, and a good quality product was gotten. However, SS before drying is 100
When it is (g / l) or more, the SS content is solidified into particles and the evaporation efficiency of moisture in the interior is lowered, so that the moisture content after drying is as high as 13% or more, which does not satisfy the moisture condition described above, and the product is not manufactured. Was not obtained.

In the second aspect of the invention, since the water content of the liquid dry matter and the water content of the solid content are adjusted to 11% or less, respectively, the water condition as feed for distribution (summer 12% or less, winter 13% or less). Satisfies the requirements and obtains high quality products.

In the third aspect of the invention, the mixing ratio of the dried solid content to the dried liquid content is important. Table 2 shows the mixing ratio of the dried solid content to the dried liquid content and the product evaluation.

[0016]

[Table 2] As can be seen from Table 2, when the mixing ratio of the solid dry matter to the liquid dry matter is less than 10: 1, it tends to absorb moisture and the dry matter is solidified after storage for 1 month or more, which causes a problem in storage stability. is there.

However, when the mixing ratio of the dried solid content to the dried liquid content is 10: 1 or more, the dried solid content contains a large amount of fibers and exhibits a buffering effect, so that the hygroscopicity is improved and the solidification occurs. No change occurs due to long-term storage, and livestock feed having excellent preservability can be obtained.

The contents of the present invention will be described below with reference to a preferred embodiment. The present invention is not limited to these examples.

The method for producing the feed obtained from the shochu lees according to this example is as follows.

That is, the shochu lees are separated into a liquid content and a solid content,
After adjusting the SS of the liquid component to 100 (g / l) or less, the liquid component and the solid component are separately dried. afterwards,
Separately dried liquid dry matter and solid dry matter are mixed to produce a feed. At this time, the water content of the dried liquid and the dried solid is adjusted to 11% or less. The mixing ratio of the solid dry matter to the liquid dry matter is 10: 1 or more.

The method for producing the feed obtained from the above-mentioned shochu lees will be described using specific numerical values.

Shochu lees 10 obtained in the distillation process for producing shochu
0 kg (water content 90%) was subjected to solid-liquid separation using a screw press to obtain a liquid content of 95.1 kg (SS 90 g / l) and a solid content of 4.9 kg (water content 65%). Next, the liquid content was dried using a disk dryer and the solid content was dried using a vertical dryer, to obtain 9.5 kg (water content 11%) of the liquid content dried product from the liquid content and 1. 9 kg (water content 11%) of a solid content dried product was obtained. After that, both were mixed at a mixing ratio of 10: 2 (mixing ratio of 10: 1 or more) to produce livestock feed.

As described above, when the liquid dry matter and the solid matter dry matter are mixed, the solid matter dry matter exhibits a buffering effect and the hygroscopicity is improved. As a result, when the livestock feed obtained by mixing the dried liquid matter and the dried solid matter is stored for a long period of time, changes such as solidification due to absorption of moisture do not occur, and excellent storage stability is obtained.
