Description

Manufacturing Method of Farming Materials Using Plant Waste Resources

1 is an exemplary front view of a compressor with a portion of the present invention cut away;

2 is a cross-sectional view taken along the line A-A 'of FIG. 1 of the present invention.

The present invention is a mixture of urea and alkaline liquids such as sawdust, rice hulls, plant stems, grass roots, etc., which are agricultural waste resources, using a heat compression mechanism as shown in the illustrated embodiment. It is combined with thermal compression machinery to apply physical and chemical treatment of compression and frictional heat to expand and absorb the ammonia into the vegetable base tissue through the action of ammonia compounding, breaking, twisting and increasing. It is a versatile product that can be easily manipulated and manufactured in a soft rice bran state with excellent roughness and no roughness. The present invention relates to a method for producing agricultural materials using plant waste resources, which has been studied for the purpose of being fully recycled and recycled to waste resources.

Although Korea has a considerable amount of agricultural waste resources such as rice straw, rice hulls, flower roots and plant roots, and soybean bark, it has not yet been able to supply its own feeds. In particular, the dairy sector has been hampered by the unreasonable management of dairy production, breeding rate, and economic life due to the shortage of forage and the acidic feed of rich feeds. Rice straw is also boiled and fed to cash as a conventional breeding method, and thus the fuel consumption, labor cost, and multi-head breeding are considered to be meaningful in the present invention in terms of development of forage resources, which are energy sources for livestock raising, and effective use of agricultural by-products. will be.

There are many ways to produce forages using waste resources, but there was no easy way to make them on a small scale.

Using the chaff from the American Science and Chemistry in an emergency (非常) a high-temperature high-pressure ammonia _{(80-100㎏ / ㎠) (NH 3} ) treatment destroys the chaff tissue but also the following method of a non-single-back Science This special large Small scale implementation was difficult due to the need for an apparatus, and there were acid cleaning methods for rice straw and ammonia spraying methods, but this work was also very complicated and required a considerable time for manufacturing. In addition to the need for a large amount of washing water during the cleaning process, pollution is also generated by wastewater treatment of acid and alkali.

In the present invention, as a result of improving the above-described factors, the present invention has been invented a complex action of the thermophysical chemistry of the compressor, urea, and alkali, which will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the extruder (1) is made up of 6-10 mm2 of rice hulls, sawdust, flower roots, plant residues, root bark, etc. in the upper absorber (1 '), and urea (Urea) and sodium hydroxide (NaOH). After spraying the solution to make the water content 20-35%, and inputting it, it is heated in a state of being pressed down on the inclined surface 2 'formed at the distal end by the rotating power of the screw 2 rotated in the compressor 1, and the compression chamber The plant substrate transported to (3) has the elevated temperature up to 65-120 ℃ due to the compression friction, and the absorption of ammonia gas due to fiber breakdown, torsion and urea decomposition is achieved. .

Thus, the vegetable substrate compressed and heated in the heating compression chamber (3) is cut by the cutting knife (4) at the discharge port, and the pressure rapidly decreases during discharge, so that the water vapor and carbon dioxide accumulated in the vegetable substrate and The explosive force caused by the explosive force caused by the rapid expansion and expansion of ammonia gas results in the expansion and destruction from the inside of the fiber, and the resultant object becomes the soft rice bran without roughness. Being a flexible porous material to be prepared in detail according to the comparison table as follows.

[Comparison Table]

When the mixture of urea and sodium hydroxide solution is heated, carbon dioxide (CO ₂ ) and ammonia (NH ₃ ) gas are denatured.

When describing the action during extrusion as a key element in the present invention, when the screw is pressed in the extruder, the sprayed urea and alkaline solution of the substrate first completely penetrates into the fiber due to the pressure and twisting of the crumbs and is contained therein. Alkaline is dissolved or decomposed into resins, liguning, pantosan, and packaging that are strongly bound to the substrate to swell and soften the fibers, and on the other hand, it acts as a urea to deoxidize Carbon (CO ₂ ) and ammonia (NH ₃ ) gas will be generated.

Under high pressure, ammonia gas is combined with the base fiber and remains as organic nitrogen, which is absolutely necessary as a ruminant feedstock. The vapor pressure by pressurization is 10-15㎏ / ㎠ and the plant fiber becomes a high-pressure cooker and the decomposition of the substrate proceeds easily.In the heating compression chamber 3, the substrate is subjected to high temperature and high pressure to undergo a physical chemical reaction. (有機 窒 素 體) is created here.

Thus, the vegetable substrate is extruded into a solid body at the outlet, so that it is cut with a cutting knife (4) and at the same time, the pressure is rapidly lowered, and the substrate is exploded by the explosive diffusion force of the gas contained in the substrate. The breakage is made from the inside of the fiber to create a smooth rice bran state.

The substrate fiber produced by the above method is heated by screw compression. Increase. Alkaline, which has been endured by the twisting, breaking, etc. of the fibers, is mixed with ligaments. It is a compound, which is a very suitable forage for ruminants, and it has good digestion absorption when feeding livestock and no ammonia poisoning due to "urease".

The reason why it is difficult for livestock farmers to raise urea is because they are concerned about ammonia poisoning of ruminants, but when urea is fed to ruminants, it is a microorganism group that is in the first place of livestock. This is because "urease" produced by the urea is rapidly decomposed into ammonia gas, which is rapidly decomposed into ammonia, and is converted into high concentrations in the blood and ammonia poisoning occurs. Therefore, in the present invention, the urea works with alkali, and once decomposed into ammonia gas by pyrolysis, it is combined with vegetable nitrogen at high pressure due to the operation of the screw with organic nitrogen and produced in the rumen No. 1, unlike single-element feeding. There is no ammonia generation due to the "urease". Urea is once decomposed into ammonia and fed as a compound at high temperature and high pressure so that no side effects due to "urease" occur.

EXAMPLE

The raw material of rice husk, sawdust, flower, and plant residues, roots and bark is 6-10 mm2. In 100 kg of 100 kg of urea dissolved in 100 l of fresh water and 1-2 kg of sodium hydroxide (NaOH). Was dissolved in 100 liters of fresh water in equal proportions and evenly sprayed on the pulverized vegetable substrate, and the water content was 20-35% .Then, it was fed into an extruder and compressed by transfer with a screw. When the pressure is rapidly lowered to expand and break from the inside of the fiber.

Claims (1)

As described above and shown in the text, 1-2% caustic soda (NaOH) solution and 3-5% urea (Urea) solution are sprayed in the same ratio, and the water content is 20-35%. A method of manufacturing a farm material using plant waste resources, characterized in that the internal pressure of the fibrous internal tissue expands and breaks down when the heat is compressed and discharged at a compression chamber temperature of 65-120 ° C.
