Abstract

PURPOSE: To safely and inexpensively obtain the resources for fertilizers and feed as the fertilizers and feed free from offensive odor pollution as soil conditioners by subjecting the internal organ residues of shells and shellfishes to desalting of salt-components, then to dehydrating, followed by adjusting of particles with a primary crusher and a pulverizing machine.

CONSTITUTION: The internal organ residues of the shells and shellfishes are charged into a washing machine to remove the deposits, such as salt-components, sludge and dust, of the respective residues, by which the salt-components are completely removed. The residues subjected to the removal of the salt-components are then dehydrated by a drying machine and the particles are properly adjusted by the primary crusher and pulverizing machine to obtain the desired fertilizers and feed. In this process, the shells may be made into any grain size and the commercialization of the products at the grain sizes suitable for respective applications is made possible. The powder of the shells produced by this process is completely removed of the salt-components and, therefore, salt damage is averted and the powder is optimum as the fertilizer of alkaline materials. Since the shells and their internal organ residues are easily soluble from mineral lime and has a fast-acting property and, is, therefore, usable as the feed of livestock animals requiring much calcium and for poultry as well.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a method for producing fertilizer and feed from shell and shellfish offal residues.

B. Conventional technology Seashells and shellfish viscera residues have traditionally been dumped at sea or incinerated, and currently are not used as resources at all. If you leave shells and shellfish viscera residue as is,
This leads to rancidity and a foul odor that emits a foul odor. In order to avoid this, if they were given directly to chickens, other animals, and plants, the salt in the shellfish would inhibit their growth and cause diseases.

C Problems to be Solved by the Invention The greatest feature of the fertilizer and feed produced by the method of the present invention is that all salt has been removed, and since extremely fine particles can be produced, animal living organisms are While increasing the required amount of calcium, it has excellent soil fertility recovery and fertilizing effects, so the resource can be provided safely and inexpensively as a soil conditioner and as fertilizer and feed without odor pollution.

D. Means for Solving the Problems The present invention completely desalinates the salt adhering to shells and shellfish viscera residue using a washing machine, and removes the salt from shells and shellfish viscera residue using a coarse crusher and a fine crusher. The residue is pulverized to make it easily ingestible, and it solves the problems of the prior art described above.Example Next, the manufacturing method of the present invention will be explained with reference to an example. First, shells are put into a hopper, and then stored in a washer using a conveyor belt inside the hopper. This washer is rotary and integrated with a drum, inside which there are protruding blades that scrape up the shells being washed, and 7 to 8 tons of water is constantly flowing through each drum every hour. The rotation of the drum causes a change in the water flow, through which the shells flow, causing friction between the shells and desalting the salt. While the shells are being desalinated, they are scraped up by the blades inside the drum and allowed to fall naturally. By repeating this process, the salt, sludge, dirt, etc. attached to the shells are removed, and the shells are gradually pushed out of the washer. Four tons of shells are desalinated in about an hour after being put into the washing machine.

When the shells are desalinated from the washer, they are further washed in a fountain shower during transportation, and then placed in a rotary dryer and dried for about 2 minutes at a temperature of about 80°C.

The dried seashells are crushed in a coarse crusher, further finely pulverized in a fine crusher, and then passed through a v-tali sifter to adjust the particle size of the shells.

On the other hand, the remaining shellfish viscera is placed in a wire mesh basket and immersed in boiling water at 90'C to 100°C for about 15 minutes for desalination. The resulting residue is dried in a dryer with warm air at 120°C to 130'C for about 1 hour. The dried residue is pulverized in a pulverizer to produce fine particles.

The finely powdered shells and shellfish viscera residue produced in this way are mixed individually or both together in a mixer depending on the purpose, and then supplied while adjusting the particle size according to social demand. That's what I do.

The powder of 7 shells and residue produced in this way is particularly effective for scallops. The analysis results of the components of scallops produced by this method are as follows.

It does not contain anything harmful to crops. Our country receives a lot of rainfall, and the cultivated soil provides calcium, magnesium,
As potassium and other substances are leached out, the soil tends to become acidic, and although it is possible to temporarily increase yields by applying chemical fertilizers alone, heavy use of chemical fertilizers causes a decline in the fertility of the soil, resulting in lower yields and the need for even more chemical fertilizers. The vicious cycle of repeated application is repeated. When this happens, the soil becomes acidic and becomes degraded. The preferred soil pH for crops is usually in the range of 6.0 to 7.0, so in acidic soils it is necessary to correct and neutralize the acidity by applying alkaline materials.

By administering calcium produced by this method as an alkaline material, healthy soil can be restored. In particular, when applied to leguminous plants that absorb a large amount of calcium, such as groundnuts and dice, the yield can be increased. Furthermore, when used as a soil conditioner, in order to change the soil reaction, it is necessary that the calcium and magnesium in the shell be easily eluted, and the finer the particle size, the farther away the calcium and magnesium are eluted. This manufacturing method allows shells to be made into any particle size, and is characterized by the ability to produce products with particle sizes suitable for each purpose. The shell powder produced by this method is completely free of salt, so it does not cause salt damage and is ideal as a fertilizer for alkaline materials.

Shells and their viscera residues are easier to dissolve than mineral lime and have a fast-acting effect, so they can be used as feed for livestock that requires a lot of calcium, and also for chickens. Livestock such as cows, horses, pigs, and sheep require a lot of calcium in their skeletons during their growth stages, and dairy cows produce a lot of milk every day.
Since a large amount of calcium is excreted in this body, daily calcium supplementation is essential. In addition to raising chickens, adult hens that are laying eggs also use calcium stored in their bones to make eggshells every day. Calcium deficiency causes abnormalities in the skeleton and eggshell formation, which in turn impedes egg-laying. It will also stop. For this reason, calcium is an indispensable animal feed, and shells in particular are the most effective feed for eggshell formation and are highly effective. When using seashells as feed, salt adhering to them can be harmful and make them unsuitable for use as feed, but this product does not pose any problems as the salt has been completely removed. In addition, although the particle size of livestock feed may vary, this production method is characterized by being able to provide feed with the necessary and effective particle size.
