[0004]

[Problems to be Solved by the Invention] In the conventional handling of squid ink, a huge amount of squid ink cannot be effectively treated, and most of them are treated as waste, so effective use of resources However, there is a problem in that the disposal cost is relatively high and the cost is high.

Many of the dyes or pigments used as a coloring means are artificially synthesized, and the dye or pigment substance itself or the process for producing these dyes or pigments, or In the process of coloring with these dyes or pigments, there are many inconveniences such as adverse effects on living organisms such as human bodies and environmental pollution.

The present invention uses crushed squid ink as a coloring means in place of the coloring means using conventional paints or pigments to measure the effective use of squid ink and at the same time to improve the life of human bodies. Coloring means with no adverse effects and without causing environmental damage, especially Direct Fast Black D, D
Dye called irect Fast Black B, Pig.Black I (CI50440) which is an oxidative condensate of aniline, and squid ink powder are used as a coloring means in place of carbon black. Had an odor peculiar to squid ink, and had an inconvenience of giving a squid ink odor to an object to be colored. An object of the present invention is to provide squid ink powder which does not impair the characteristics of natural tyrosine peculiar to such squid ink and has no odor at all.

[0007]

Means for Solving the Problems The squid ink powder and the method for producing squid ink powder according to the present invention are intended to achieve such an object. According to the invention of claim 1, the squid ink powder is heated in seawater and then dried. The squid ink powder used is a squid ink powder having a particle size adjusted to 6 μm or less. Further, in the invention of claim 2, the squid ink is heated from salt water, the heating is stopped when the salt water reaches 80 ° C, and then the squid ink to be dried does not have a temperature exceeding 80 ° C. After drying under dry condition and adjusting the water content to 8% by weight or less, this dried squid ink is crushed while the temperature of the dried squid ink during the crushing process does not exceed 80 ° C. Mold squid ink.

[0008]

[Function] Squid ink is soaked in salt water, heated in this state, heating is stopped when the salt water temperature reaches 80 ° C, the squid ink is taken out of the salt water, and dried to be squid ink powder. The squid smell peculiar to squid ink is removed by. In addition, since the ground squid ink powder is 6 μm or less and the water content is 8% by weight or less, the squid ink powder does not form an agglomerated state due to fusion, and moreover, the squid ink powder is to be colored. On the other hand, it functions to adhere in a uniformly colored state. Further, since squid ink is soaked at a low temperature of 80 ° C. or less, dried, deodorized, dried and crushed at a crushing temperature, tyrosine and sepia pigments, which are the main components of squid ink, are not destroyed.

[0009]

EXAMPLES A typical example of the present invention will be described in detail below. As the squid ink targeted here, it is preferable to use various squid inks, particularly those obtained from the ink sac of cow squid called sumika or mica. The squid ink powder of the invention of claim 1 is configured such that the squid ink is heated in salt water and then dried to have a particle size of 6 μm or less. Further, in the method for forming squid ink powder according to the invention of claim 2, these squid inks are immersed in salt water, and the salt water is heated and taken out from the salt water when the salt water temperature reaches 80 ° C. Further, this is dried so that the internal temperature of the dried squid ink does not exceed 80 ° C. so that the water content is 8% by weight or less, and the water content of the dried squid ink is 8% by weight. % So that the internal temperature of the dried squid ink during crushing does not exceed 80 ° C.

The squid ink powder and the method for forming the squid ink powder will be described more specifically. First, a fresh ink pouch taken out from a squid is dipped in salt water, and in the state of being dipped in this salt water, squid ink is taken out from the fresh ink pouch or bladder and boiled. The salt water used here has a concentration of 10% by weight or more. If the salt water concentration is less than 10% by weight, the squid odor of the treated squid ink cannot be sufficiently removed, and an odor peculiar to the obtained powder remains. When the salt water concentration exceeds 40% by weight, the squid odor contained in the treated squid ink is effectively removed, but on the other hand, there is a disadvantage that sodium chloride powder remains in the obtained powder. The salt water used for deodorizing treatment is
Ideally, the concentration is 20 to 30% by weight. Immerse a fresh squid ink pouch in such salt water. This fresh ink sac consists of squid ink solid content of 36% by weight and water content of 64% by weight.
Stew until the temperature reaches ℃, and when the internal temperature reaches 80 ℃, stop heating and remove the squid ink.

The squid ink thus deodorized is adjusted and dried in a low temperature range, especially so that the temperature of the squid ink powder during drying does not exceed 80 ° C. Drying method of this squid ink is warm air drying using warm air of 50 ℃ -60 ℃ and 1kw.
Exothermic drying using an electromagnetic wave of / H or sun drying by sun is preferable. Also, in this forced drying, it is necessary to perform a drying treatment under the absolute condition that the temperature of the squid ink, which is an object to be dried, in particular, the internal temperature does not exceed 80 ° C. Therefore, it is preferable to consider that the dried squid ink is not placed in the high temperature range.

Drying of the squid ink is preferred to be carried out in a low temperature range. When the temperature of the squid ink to be dried exceeds 80 ° C., the sepia pigment which is the main body of the squid ink is destroyed,
It becomes impossible to produce a unique black color. Therefore, in terms of drying yield, drying of squid ink is preferably performed using hot air of 50 ° C. and drying by microwave heating under the condition that the object to be dried is heated to 80 ° C. or less. Is one.

The drying of such squid ink is continued until the water content of the squid ink, which is the object to be dried, becomes 8% by weight. It is preferable that the water content contained in the squid ink is dried more reliably, and it is preferable that the water content is reduced to 5% by weight or less, and further to 3% by weight or less. The identification of the low water content of such squid ink has important meaning not only in the squid ink crushing process described below, but also in the handling and storage of the pulverized squid ink powder. There is.

The squid ink thus dried to have a water content of 8% by weight or less is in a coarse particle state having a relatively large diameter as shown in Table 1, and even if it is used for coloring in this state. It has the disadvantage of poor adhesion and uneven coloring.

[0015]

[Table 1]

Thus, the squid ink coarse powder of Table 1 having a water content of 8% by weight or less is pulverized by a dry pulverizing means. Typical examples of this dry crushing means include crushing by a jet mill and a dry ball mill, and in the case of crushing by any of the crushing means, the inside of the crusher is brought to a dry state, and the squid ink coarse powder which is the crushing target in this crusher The water content should not exceed 8% by weight. If the water content of the squid ink coarse powder that is the object to be crushed in this crusher exceeds 8% by weight, the squid ink coarse powder will be in an agglomerated state or a bound state with each other, and will be in the form of fine powder, especially 6 μm under No powder can be obtained.

Further, it is necessary that the squid black coarse powder which is the object to be crushed in the crusher is crushed in a state where it does not reach 80 ° C. or higher. When heated above 80 ° C, the sepia pigment of squid ink is destroyed and becomes unsuitable for practical use. Therefore, in the case of pulverizing with a jet mill, pulverizing with low temperature and dry air, and in pulverizing with a ball mill, the pulverizer itself is provided with a cooling structure and a closed structure to create a low temperature and dry pulverizing atmosphere. It is necessary to crush inside.

First, a concrete example of crushing dried squid coarse powder using a jet mill will be described. In the present embodiment, the coarse powder sent to the lower side of the crushing chamber of the jet mill is made to flow in this crushing chamber by jetting jet air from a nozzle arranged on the peripheral surface of the crushing chamber, and then this flow The coarse particles in the state are crushed by accelerating and colliding with each other with jet air, and the fine particles that have been impinged and crushed are sent to the classification rotor in an upward flow, and the fine particles classified by this classification rotor are sucked and captured by the suction blower. At the same time, a jet mill is used in which the coarse powder particles are lowered along the inner wall of the crushing chamber by their own weight and returned to the coarse powder in the fluidized state. In the jet mill used in this example, a nozzle having a nozzle diameter of 4 mm was used and jet air of 3.2 m ³ / min (atmospheric pressure conversion) having a nozzle gauge pressure of 6 kg / cm ^{2 was} fed into the crushing chamber to crush the coarse powder. is doing. Also, the classifier used with the jet mill in this example has a rotation speed of the classification rotor of 9,000 rp.
m, the suction amount of the blower is 4 m ³ / min (converted to atmospheric pressure), and the crushing chamber pressure is 0.07 mmAq. For the pulverization and classification of the coarse powder to be pulverized, a jet mill of a type other than the jet mill described above may be used, or a dry pulverizer other than the jet mill may be used.
Alternatively, the crushing and the classification may be performed separately.
Therefore, even if the crusher is configured by means such as a ball mill that has mechanical crushing, and the classifier is configured by means that includes a method of air volume classification by true specific gravity, a method of sieving by volume, etc. good.

Into such a jet mill, the dry squid ink coarse powder shown in Table 1 above was put, and the absolute humidity was 0.02 kg H ₂ O /
Dry air lower than kg (1 kg of air contains 0.002 kg or less of dry air) is put into the jet mill to grind dry squid ink coarse powder. At the time of this crushing, be careful so that the temperature in the jet mill does not exceed 60 ° C. In this example, the squid ink temperature during crushing is 80% by crushing and classifying so that the classified product becomes 6 μm under at 50 ° C. Effectively kept below ℃. The squid ink powder obtained by this pulverization and classification has the particle size distribution shown in Table 2 and has a particle size of 2 μm.
It was confirmed that the m-under was 54.3% by weight, was made into an ultrafine powder, and the individual grains maintained an independent state.

[0020]

[Table 2]

Next, the dried squid ink coarse powder in Table 1 was crushed using a dry ball mill to obtain crushed squid ink powder. In this pulverization with a dry ball mill, zirconia ceramic balls with a diameter of 3 mm are used in a 5.4 liter capacity ball mill.
A liter-loaded one was used, the inside of this ball mill was used as a closed space, and the inside of this ball mill was used as a low temperature dry atmosphere. The ball mill used for this crushing is a state in which cooling water is constantly supplied so that the inside temperature of the ball mill during crushing is 60 ° C or less, more practically 50 ° C or less by covering the outside with a cooling jacket. In addition, when the dry air of 0.002 kgH ₂ O / kg was fed into the closed mill to dry the air in the mill and pulverized, the temperature of the squid ink during pulverization was effectively kept at 80 ° C or lower. When pulverization of the dried squid ink coarse powder of Table 1 was continued for 20 minutes by the above method, superfine squid ink powder having the particle size distribution of Table 3 could be obtained.

[0022]

[Table 3]

The squid ink powder obtained here is crushed to have particle sizes of 6 μm under and 4 μm under, and
Each particle size is maintained as an independent particle state, there is no destruction of the sepia pigment, there is no odor, and it has a characteristic deep black color tone.

The squid ink powder obtained above has an odor effectively removed, is an ultrafine powder, and has a dark ink color tone peculiar to squid ink, and its composition is composed of amino acids. Since it is tyrosine, it is well-suited to the living body and can be used as a coloring means that is not harmful to living organisms and can be used for a wide range of purposes as a coloring means that does not cause environmental damage. Particularly, it is suitable for use as a hair dyeing alternative to conventional hair dyes that are highly toxic and carcinogenic, or as an eyebrow or the like, or as a coloring means for food, coloring for tableware or infant toys. ing. Further, since the particle size of the squid ink powder obtained by crushing is uniformly adjusted to 6 μm under, it should be used as a coloring means for clothing, a coloring means for leather, plastics, etc. without uneven color. You can In addition, the solvent,
When used by being mixed with a writing ink, a printing ink, a paint, etc., it has good dispersibility and can be used as one having a uniform tone density.
