Eco-friendly equipment to produce amino acid liquid fertilizer using livestock blood and method for manufacturing amino acid liquid fertilizer using the same}

The present invention relates to an amino acid liquid fertilizer manufacturing apparatus, and more particularly, to an eco-friendly device for manufacturing an amino acid liquid fertilizer using the blood of livestock collected from a slaughterhouse as a main raw material, and a method for manufacturing an amino acid liquid fertilizer using the same.

Slaughter blood generated by slaughtering livestock such as cattle, pigs, and poultry is a livestock by-product, and although it is a useful resource rich in various proteins, most of it has been simply disposed of and has been a major cause of environmental pollution as well as waste of protein resources. .

Slaughter blood is rich in various proteins, nutrients and minerals. In particular, the plasma portion of slaughtered blood contains protein components such as albumin and globulin, and the blood cell portion contains a large amount of a protein component called hemoglobin.

Accordingly, a study to extract useful substances such as protein amino acids from slaughter blood or recycle them as raw materials for feed and fertilizer, as it is newly recognized as a useful resource that can be recycled, away from the conventional view that slaughtered blood was simply regarded as waste. Has been made in various ways.

The field in which slaughter blood is mainly used is the manufacture of animal protein feed. After collecting slaughter blood generated in slaughterhouses, it is supplied as blood meal obtained by drying and powdering it.

However, in recent years, research on a method of manufacturing a liquid fertilizer using live blood, that is, livestock blood itself, not in the form of blood meal, has been conducted. As described above, in order to manufacture liquid fertilizers using blood itself (live blood) as a main raw material, it is necessary to precisely pulverize (liquefy) livestock blood during the manufacturing process, add enzymes, and then proceed to decomposition in a fermenter.

In general, slaughter blood collected from slaughterhouses is incidentally mixed with blood vessels, tendons, hair, etc., and the collected blood itself is easily coagulated.Therefore, it is necessary to undergo a pulverization process before putting the slaughter blood into the fermentation tank to disassemble it. It can be converted more than 99% into 20 kinds of amino acids. At this time, if the pulverization is insufficient, the blood cannot be decomposed and remains as a protein, resulting in a bad odor, and the amino acid conversion rate is also lowered.

However, in the conventional amino acid liquid fertilizer manufacturing apparatus, the means for pulverizing the blood collected in the slaughterhouse is a millstone method, that is, two crushing plates are made of a friction type, so that noise is large and power consumption is excessive.

In addition, the conventional amino acid liquid fertilizer manufacturing apparatus using a millstone type pulverization means does not crush foreign substances such as hairs contained in slaughter blood well, so it is necessary to increase the number of regrind or to add a small amount of slaughter blood. There is a problem that the cost increases due to a longer time required, and in the summer when the temperature is high, the blood raw material is gradually decayed by the frictional heat of the grinder before the process is completed, thereby generating an odor.
