Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a method for producing a solid feed for livestock of corn steep liquor and / or fish soluble.

[Prior Art] Corn steep liquor is one of the by-products when producing starch (corn starch) from corn as a starting material, and contains a large amount of soluble proteins, peptides, and amino acids, and further contains lactic acid, sugars, inorganic substances, Vitamins, nucleic acids,
And many nutrients such as unknown growth factor (UGF).

Due to this excellent soluble nutrient composition, corn steep liquor is widely used as a fermentation medium for amino acids and the like or a medium for producing antibiotics.

On the other hand, since corn steep liquor is a viscous liquid containing about 50% water, it is used for livestock feed as a gluten feed or pellet feed that has been processed in addition to the fibrous portion of the by-product produced at the same time. It is mainly composed of adhesive binders, and other products include malt, starch meal, and corn steep liquor powder that is an adsorbed feed that uses other adsorbent bases.

Fish soluble is a viscous liquid with a water content of about 50 to 85%, which is fish juice discharged during the process of incorporating fish and during the production of fish meal. It contains water-soluble proteins, amino acids, and abundant nutrients such as water-soluble vitamins, minerals, and unknown growth factors (UGF), and its typical use is fish soluble that is adsorbed on an appropriate adsorption base. It is an adsorbed feed and is widely used mainly as feed for poultry. As described above, since corn steep liquor and fish solubles contain abundant soluble nutrients, they are used in animal feed applications in the form of processed protein feeds, adsorbed feeds and pellet binders as described above. Since liquor and fish soluble are essentially viscous liquids containing about 50% water, it is difficult to use them directly as livestock feed.

[Problems to be Solved by the Invention] In Japan, where resources are scarce, most of the resources are supported by imports from foreign countries. Livestock is not an example either, and most of the feed ingredients for livestock must be imported from foreign countries.

On the other hand, quality and price are major issues in livestock management amid international competition. Especially at this price, the feed cost is a very important part.

Corn steep liquor is a by-product of starch production, and fish soluble is a by-product of fish meal production or a secondary product generated by the treatment of built-in effluents of fish debris. It is important to positively and cheaply utilize these potential nutrient sources as feed for livestock in terms of effective use of limited resources as well as burrs that help reduce feed costs.

However, since corn steep liquor and fish solubles are viscous liquids containing 50% water, it is difficult to handle them especially in terms of alteration, transportation, storage, and feeding method. It is difficult to use it directly as livestock feed.

In order to achieve this object, the present invention is to solidify corn steep liquor or fish soluble and convenient and inexpensive, and utilize the corn steep liquor or fish soluble as a livestock feed.

[Means for Solving Problems] The basic principle of the present invention is that corn steep liquor and fish soluble are mainly used and magnesium chloride or calcium chloride as a solidifying agent is dissolved by adding a minimum amount of water, and further necessary. Then add alcohols and pH 3-9
By adding phosphoric acid in a uniform solution in the range of 1 and mixing uniformly, it is possible to easily solidify at room temperature.

That is, the present invention is possible in the range of 20 to 90 (W / W)% corn steep liquor and / or fish soluble, but corn steep liquor and / or
Or, since corn steep liquor and / or fish soluble is essentially 50 to 90 (W / W)% since it is mainly composed of fish soluble, magnesium chloride and / or calcium chloride is 0.5 to 20 (W / W). )%
Is added directly and stirred, dissolved or previously dissolved with a minimum amount of water and then added, and then a pH adjusting agent is added to make a uniform solution of pH 3 to 9, and phosphoric acid 0.2 to 15.0 (W
/ W)% is added to form a uniform liquid and then solidified, and a method for producing a solid feed for livestock, which further comprises alcohols 1 to 30 (W / W)% in addition to these The present invention relates to a characteristic method for producing a solid feed for livestock. Here, corn steep liquor or fish soluble is a liquid containing water of about 50 (W / W)%, and in the present invention, water of 25 to 5 (W / W)% is used as necessary.
Add in the range of.

Water is necessary for dissolving the solidifying agents magnesium chloride and calcium chloride, and is important for imparting an appropriate fluidity to the mixture of corn steep liquor or fish soluble and for forming a uniform liquid. The water in the present invention is preferably in the range of 20 to 50 (W / W)%, and is not necessarily added considering the water content from the corn steep liquor or the fish soluble. However, since corn steep liquor and slightly fish soluble are viscous liquids, magnesium chloride and calcium chloride, which are solidifying agents, can be dissolved in water in advance at 20-40 (W
It is simpler and more effective to dissolve it in a concentration of / W)% and add this.

As the solidifying agent, magnesium chloride and any one of magnesium chloride and calcium chloride or a combination thereof can be used, and the range thereof is 0.5 to 10 (W / W)%, preferably 1.3 to 8 (W / W)%.

In the present invention, a uniform solution of corn steep liquor and fish soluble in which a solidifying agent for magnesium chloride and calcium chloride is dissolved is adjusted to pH 3 to 9, preferably pH 5 to 8, and then phosphoric acid is added. Since the corn steep liquor and the fish soluble at this time are acidic liquids having a pH of around 3 to 4,
The pH adjuster essentially uses alkaline substances such as sodium and potassium.

As described above, the present invention has a range of weak acidity to weak alkalinity and almost no thermal reaction, so that soluble proteins, amino acids, vitamins and the like contained in corn steep liquor and fish soluble can be kept stable. . Therefore, the present invention is characterized by a method for producing a solid feed capable of suppressing the loss of rich nutritional components of corn steep liquor and fish soluble.

Furthermore, in the present invention, the addition of alcohol is useful for the catalytic action effect of the solidification reaction and the preservation effect of the final solidified feed, and is 1 to 30 (W / W)%, preferably 2 to 10 (W / W).
W) Add in the range of%.

According to the present invention, all the additives including the solidifying agent are not harmless to livestock, but rather, they are listed as a feed ingredient and are easily available.

Further, the equipment for producing solid feed for livestock according to the present invention,
Only a mixing tank of appropriate size and a simple stirrer,
No special equipment is required.

[Operation / Effect] The present invention uses corn steep liquor and fish soluble as feed ingredients minerals such as magnesium chloride and calcium chloride as a solidifying agent, and easily solidifies at room temperature under weakly acidic to weakly alkaline conditions to give solids for livestock. It produces feed, and its actions and effects are as follows.

Since there is no thermal change in the reaction in the range of weak acidity to weak alkalinity, loss of abundant nutritional components such as soluble proteins, amino acids and vitamins contained in corn steep liquor and fish soluble is small.

All the components used as a solidifying agent are soluble macro minerals such as magnesium, calcium, phosphorus, sodium and potassium, which can be effectively used as a feed component for livestock.

Alcohols can be expected to have the effect of promoting the solidification reaction and the effect of preserving corn steep liquor and fish soluble, as well as the supplemental nutritional effect of livestock feed.

The intermediate product of the reaction process exhibits extremely high thixotropic properties and maintains a low-viscosity and fluid state for several hours even under low-speed stirring.

Further, because of the reaction, it is not affected by thermal factors and can be easily solidified at room temperature. This represents a very useful feature that is deeply involved in the equipment for producing corn steep liquor and fish soluble solid feed.

That is, the present invention is a facility device only for dissolving the solidifying agent, stirring the corn steep liquor and fish soluble, a suitable container for satisfying uniform stirring with phosphoric acid, or a tank and a simple stirrer, which is extremely simple. It is cheap.

From the above, the present invention can easily and inexpensively and easily solidify the corn steep liquor and the fish soluble, and therefore the corn steep liquor and the fish soluble can be easily handled, and the feeding method and the transportability are improved. In addition, since the occurrence of mold and decay is improved, it is a useful method for utilizing corn steep liquor and fish soluble as feed for livestock.
