According to the invention of claim 1, the squid ink powder and the method for producing squid ink powder according to the present invention achieve the above object. ,
The squid ink powder has a particle size of 6 μm or less and is adjusted such that the water content of the pulverized powder is 8% by weight or less. Further, in the invention of claim 2, the squid ink is dried under a drying condition such that the temperature of the squid ink to be dried does not exceed 80 ° C., and the moisture content thereof is adjusted to 8% by weight or less. After that, the dried squid ink is crushed in a state where the temperature of the dried squid ink during the crushing process does not exceed 80 ° C. to form the squid ink. Further, in the invention of claim 3, the squid ink powder obtained by crushing is deodorized with methyl alcohol before crushing, during crushing, or after crushing to obtain squid ink powder having no odor.

[0008]

The crushed squid ink powder is 6 μm or less, and the water content is 8% by weight or less, so that the squid ink powder does not form an agglomerated state due to fusion and the coloring object It functions so as to adhere in a uniform colored state. Further, since the squid ink is dried at a low temperature of 80 ° C. or less, and dried and crushed at the crushing temperature, the tyrosine and sepia pigments, which are the main components of the squid ink, are not destroyed.

[0009]

EXAMPLE A typical example of the present invention will be described in detail below. As the squid ink targeted here, various squid inks, particularly those obtained from the ink sac of cow squid called sumika or mica are preferably used. In the squid ink powder according to the invention of claim 1, these squid inks are crushed to have a particle size of 6 μm or less and a water content of 8% by weight or less. In the method for molding squid ink according to the invention of claim 2, these squid inks are dried so that the internal temperature of the squid ink during drying does not exceed 80 ° C., and the water content thereof is 8% by weight. The squid ink is crushed so that the water content of the dried squid ink is maintained at 8% by weight or less, and the internal temperature of the dried squid ink during crushing does not exceed 80 ° C. To do so.

The squid ink powder according to the invention of claim 1, the method of forming squid ink powder of claim 2 and the squid ink powder according to claim 3 will be described more specifically. First, the fresh ink pouch taken out from the squid is dipped in a methyl alcohol solution to remove the peculiar odor of squid ink. This dipping treatment in methyl alcohol requires performing until the obtained ground squid ink powder does not have an odor peculiar to squid ink. In this example, the dipping treatment in a methyl alcohol solution is repeated 3 times to crush without odor. I got squid ink powder. Instead of this dipping treatment with methyl alcohol, the fresh India ink sacs may be washed with methyl alcohol.
Alternatively, the smell may be eliminated by spraying methyl alcohol onto the fresh ink pouch. Further, the odor removal treatment of squid ink with methyl alcohol is more preferably performed in a state where the squid ink is taken out from the ink pouch, and it is preferable to treat the squid ink taken out from the ink pouch in a state of being dispersed in methyl alcohol. Particularly favorable results have been obtained.

The squid ink thus treated with alcohol is adjusted to a low temperature range, in particular, adjusted so that the temperature of the squid ink powder during drying does not exceed 80 ° C. and dried. As a method for drying the squid ink, warm air drying using warm air of 50 ° C. to 60 ° C., exothermic drying using electromagnetic waves of 1 kw / 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 the object to be dried, especially the internal temperature does not exceed 80 ° C. It is preferable to consider that the dried squid ink is not placed in a 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. The removal of the water content by drying the squid ink is preferably more surely removed, and is preferably 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 an 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.

Thus, the squid ink dried to have a water content of 8% by weight or less is made into coarse particles 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 shown in Table 1 having a water content of 8% by weight or less is pulverized by a dry pulverizing means. Typical examples of the 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 in a dry state, and the squid ink coarse powder which is the crushing target in the 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 under 6 μm. No powder can be obtained.

Further, it is necessary that the squid ink coarse powder which is the object to be crushed in the crusher is crushed in a state where the temperature 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 crushing by a jet mill, low temperature and dry air crushing is performed, and when crushing by a ball mill, a cooling structure and a closed structure are provided in the crusher itself to create a low temperature and dry crushing 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 this 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 pulverized by accelerating and colliding with each other with jet air, and the fine particles that have been subjected to collision pulverization 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. In addition, 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 3.2 m ³ / min (atmospheric pressure conversion) having a nozzle gauge pressure of 6 kg / cm ² was sent into the pulverization chamber to pulverize 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.
The crushed particles are classified so that the suction pressure of the blower is 4 m ³ / min (converted to atmospheric pressure) and the pressure in the crushing chamber 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.
Further, a method of separately crushing and classifying may be used.
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 dried 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 dry air having a water content of 0.002 kg or less) is put into the jet mill to pulverize 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 temperature of the squid ink during crushing is 80 by crushing and classifying so that the classified product is under 6 μm 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,
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-based 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 the outside is covered with a cooling jacket and cooling water is constantly supplied so that the temperature inside the ball mill during crushing is 60 ° C or less, more practically 50 ° C or less. 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, ultrafine squid ink powder having the particle size distribution of Table 3 could be obtained.

[0022]

[Table 3]

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

The squid ink powder obtained in the above step is an ultrafine powder, has a dark ink color tone peculiar to squid ink, and its composition is an amino acid type tyrosine. It can be used as a coloring means that is not harmful to living organisms and can be used for a wide range of applications 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, which is highly toxic and has a carcinogenic risk, or as an eyebrow, etc., or as a coloring means for foods, coloring means for tableware or toys for infants. ing. Moreover, 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 and plastics, and a coloring means without uneven color. You can Furthermore, when used in a solvent, a writing ink, a printing ink, a paint, etc., it has good dispersibility and can be used with a uniform tone density.

[0025]

The squid ink powder according to the present invention has a particle size of 6 μm.
It is under-prepared and contains 8% by weight of water.
As described below, the squid ink powders have the feature that they are not welded to each other and are not aggregated or bound to each other and are evenly attached to the object to be dyed. In addition, when it is mixed with paint or ink, it has good dispersibility, and it has a feature that it is uniformly dispersed in paint or ink and forms a paint-adhering surface or an ink-adhering surface without color unevenness. In addition, since squid ink is an amino acid type tyrosine and its colored pigment is sepia, it has no toxicity and is harmful to the process of forming squid ink powder, its use process, and even the object to be used. It has the characteristic that it does not cause properties, and it is particularly harmless even in biological staining. Then
Both squid ink is dried and crushed, and the squid ink to be crushed is treated so that the temperature does not exceed 80 ° C.
