Abstract

PURPOSE:To easily perform treatment such as conversion into feed and incineration by cutting or squashing jellyfish and thereafter heating and pressurizing them to remove moisture of jellyfish. CONSTITUTION:Landed jellyfish are cut or squashed and treated in a stage 1 and a part of moisture of jellyfish is removed. Then, jellyfish are heated by the properly heating means in a stage 2. Moisture of jellyfish is furthermore removed by evaporation. Successively moisture of jellyfish is furthermore removed by pressurizing and extruding jellyfish in a gelidium jelly shape from a small hole in a stage 3. Jellyfish are made to a state capable of being incinerated. Residue is mainly constituted of an organic compound from which moisture is squeezed. The residue is pulverized into powder or granules in a stage 4. The powder or granules are dried by sunlight or heating in a stage 5. The dried material is utilized for feed or the like. Thereafter, it is incinerated in an incinerator.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for treating jellyfish for removing water from jellyfish for use as food, feed, fertilizer or the like, or for incinerating.

[0002]

2. Description of the Related Art There are many types of jellyfish, and there is a large difference between very large and small jellyfish. And the water content is 95-98%, and the content of organic compounds is 2
Only ~ 5%. Thermal power, hydroelectric power generation, etc. consume a large amount of seawater as fresh water for evaporation and water for cooling, but equipment for removing unnecessary substances from seawater is required. , Tens of tons of jellyfish are generated each day, which attaches to membranes and clogs the intake of seawater, so they land on jellyfish. However,
Landed jellyfish oxidize and become a foul odor pollution, and even if they are incinerated, the jellyfish themselves cannot be incinerated because they have a moisture content of 95-98%, so they are unavoidably landfilled.

Of the jellyfish, only the edible jellyfish is in the bizen jellyfish position, the part of the jellyfish's umbrella is dipped in lime and myoban, exposed to drain blood, and the semitransparent or yellow one is highly concentrated. It is salted and stored, and when used, it is desalted and processed.

[0004]

For the above landfill disposal, it is necessary to secure a place for landfill, but it is very difficult to secure the place. Even if it is landfilled, the jellyfish will oxidize and produce a bad odor, and the water (including salt) of the jellyfish will ooze out, causing salt damage not only to the landfill but also to the land around it, causing the plants to die. In addition, jellyfish must be transported from landing to landfill for landfill, and many trucks must be used for that purpose. However, the salt rusts the trucks immediately, and it is very difficult to secure the necessary trucks because they are disliked. In the above processing of medusae, which is edible, only about 20% of water can be removed, and the storage method and cooking method are limited.

It is an object of the present invention to provide a treatment method for removing most of the water content of jellyfish to make residual organic compounds into powders or granules that are easy to handle or dispose of.

[0006]

First, in Step 1,
Cut or crush landed jellyfish. This is to accelerate the movement catalyst of the concentration molecule. This process removes some of the water from the jellyfish.

In step 2, heating is performed. This heating method is
An electric heater, electromagnetic waves, lime, hot water, steam or the like may be used, or other heating method may be used. This heating further removes part of the water content of the jellyfish.

In step 3, pressure is applied. As a method,
It is preferable to push it out from the small hole like a tokoroten or to pass it through the gap between two rotating rollers. You may use other pressurizing methods, such as pressing and extrusion by a screw conveyor. At this time, it is preferable to use a member having small holes or a pressure member such as a roller while heating.
By this pressurization, the water content of the jellyfish becomes about 30%, and most of them can be incinerated.

In step 4, the residue mainly composed of the organic compound, which has been squeezed out of water by pressing in step 3, is pulverized into powder or granules.

In step 5, the powder or granules formed in step 4 are dried by sun or heating. By this drying, the water content of the powder or granules becomes about 0.5 to 0.7% of the water content of the landed jellyfish. The dried powder or granules can be stored or transported in a container or bag and can be used in various fields. Step 5 can be omitted depending on the purpose.

When disposing of jellyfish, step 3
It may be incinerated after squeezing out the water in step 4, forming the powder or granules in step 4, or drying in step 5.

The removed water is returned to the sea. This water removes most of the jellyfish's organic matter and does not contaminate seawater.

[0013]

The cutting or crushing of the jellyfish in step 1 removes some of the water content of the jellyfish, and thereby accelerates the kinetic catalysis of concentration molecules. The heating in step 2 removes some of the water from the jellyfish. Pressurization in step 3 squeezes out most of the jellyfish's water. The pulverization in step 4 makes the remaining organic compound into a powdery or granular form, which facilitates storage, transportation, and use.
Drying in step 5 further removes water from the powder or granules, leaving very little water.

[0014]

[Experimental Example] 100 g of a water jellyfish having a water content of 98% was treated in the above process. The cutting in Step 1 brought the water content to about 80%. An electric heater was used for heating in step 2. As a result, the water content became about 50%. The pressurization in step 3 was to push out the small hole member through a large number of small holes in a tokoroten method while heating the small hole member. The water content was about 30. Crushed by step 4,
Then, it was dried with hot air in Step 5. Moisture is about 0,7
%, About 0,5% by volume.

[0015]

[Effects] According to the present invention, it is possible to treat jellyfish at the landing point with a simple device, easily remove water from jellyfish, and use residual organic substances for food, fertilizer, feed, etc., or incinerate them. It does not cause salt pollution. According to the present invention, there is no need for land acquisition, transportation, landfill tools and work for landfill.
