題点があった。2. Description of the Related Art Naturally exposed rock salt, solar salt, or salts produced by the ion exchange membrane method are all usually in cubic crystal form. A salt having good fluidity is required for ease of use depending on the application, and the fluidity of the salt is considered to be determined by the water content on the surface of the crystal particles and the size of the contact area between the crystal particles. And, the dry salt is better than the wet salt, the larger particles are better than the small particles, the particle size distribution is nonuniform, and the particle shape is better than cubic crystals, and the fluidity is better and the solidification is less, which is good. It can be called salt. However, when a constant particle size and particle size distribution are required at a constant ambient temperature and humidity, the spherical salts that come into point-to-point contact form a smoother salt than the cubic crystals that come into contact with each other, causing solidification. It is clear that the fluidity is low and the fluidity is excellent. Therefore, various methods have been tried for producing spherical salts. Conventionally, there is known a method for producing a spherical salt of monolithic particles from a granular salt obtained by collecting and aggregating a large number of finely divided salts or a supersaturated aqueous solution of sodium chloride (JP-A-2-83002). Is an aggregate of porous particles, bulky,
The latter had the problem of poor productivity and lack of economic efficiency.

It came to completion. That is,
In the present invention, sodium chloride or potassium chloride particles are suspended in a high temperature flame or 800 ° C or higher, preferably
It is a particle close to a true sphere obtained by contacting with a high temperature gas of 1,000 to 1,300 ℃ for a short time, spheroidizing by surface tension of the particle simultaneously with partial melting, and solidifying by cooling.

生が激しく、設備技術の上で限界がある。When a spherical salt having a particle diameter of 0.01 mm or less is to be produced, it is difficult to completely disperse the raw material particles in a flame or high-temperature gas when the raw material particles are fine. Will tend to grow and become spherical salts with a larger particle size than the target. In order to prevent this, it is necessary to add the raw material salt little by little into the flame or the high temperature gas, which is a disadvantage in economical efficiency. Conversely, when trying to produce a spherical salt with a particle size of 1.0 mm or more, contact raw material particles with a particle size of 1.0 mm or more with higher temperature flame or hot gas, or
Alternatively, it is necessary to lengthen the flame of the salt particles and the contact time with the high-temperature gas, and the steam is intensely generated due to the vaporization of the salt, which limits the technology of the equipment.

The fuel for flame or high temperature gas formation may be a liquid fuel or a gas fuel, but a clean fuel is required as much as possible, and a gas fuel 3 such as natural gas, LPG or butane gas is preferably used. At the same time, air 2 is blown into the salt supply pipe 1 at high pressure to assist combustion, and the flame 6 inside the furnace body 5,
Alternatively, the temperature of the hot gas 7 is 800 ° C or higher, preferably
The salt particles of the raw material, which are kept at 1,000 to 1,300 ° C. and pneumatically fed, are fed into the center of the high temperature flame through the salt supply pipe 1. The time for which the salt particles are exposed to the flame 6 or the high temperature gas 7 in a suspended state needs to be about 0.1 seconds. If the contact time is insufficient, the retention of spherical salt is suspended, and the particle size is relatively small. For example, a spherical salt of about 0.01 to 0.1 mm can be obtained. Even when the flame or hot gas temperature is 800 ° C or lower, only salt particles having the same particle size can be obtained.

ばよい。The degree of formation of such a spherical salt is almost the same with sodium chloride or potassium chloride, but in the case of a mixed salt of sodium chloride and potassium chloride, the melting point is higher than that of a cubic crystal having a single melting point. ~ 750 ℃ and about 100
Since it is as low as ℃, the yield of spherical salt tends to be slightly improved. It is stored in the first collection container 8 for collecting the spheroidized salt particles treated with flame or high temperature gas. Further, among the salt particles, those having a relatively small particle diameter are blown with the cooling air 10 into the transfer pipe 4 to be cooled to about 100 ° C., and are collected by the back filter 12 via the cyclone 11. Spherical salts having a diameter of about 0.05 mm or less are collected in the lower second collecting container 9. The structure of the furnace body 5 may be a horizontal type or a vertical type, but may be appropriately adopted depending on the particle size of the spheroidized salt desired.

滑性を有し、真球に近いビーズ状となっている。[Function] By allowing sodium chloride or potassium chloride particles to float while they are in contact with the flame of a combustion burner or a high temperature gas of 800 ° C or higher, preferably 1,000 to 1,300 ° C for a short time, the salt particles are partially melted and The spheroidization progresses due to the surface tension, and the salt particles solidified by cooling can be manufactured as single particles having a glass-like particle diameter of 0.01 to 1.0 mm, which is close to a true sphere. When producing spherical salts with a particle size of 0.01 mm or less,
If the raw material particles are fine, it is difficult to completely disperse them in a flame or high-temperature gas, and due to the contact between the molten particles, the particle size is enlarged, and a spherical salt having a larger particle size than the target is likely to be formed. Conversely, when attempting to produce a spherical salt with a particle size of 1.0 mm or more, the raw salt particles with a particle size of 1.0 mm or more are brought into contact with a higher temperature flame or high temperature gas, or the salt particle flame and high temperature gas The contact time needs to be long. In the granular salt produced by collecting and agglomerating fine-grained salts found in the prior art, a porous body containing a binder component is formed, but the spherical salt obtained by the present invention has crystal grains of a specific particle size. Is molten or semi-molten and spherical.
The purity is maintained at the salt purity of the raw material, and a spherical salt composed of a monolithic single structure is formed. The spherical salt of the present invention has few voids inside the particle, the surface of the particle has smoothness, and is in the form of beads that are close to a true sphere.

It has excellent practicality and economy, and the obtained spherical salt has a wide range of applications. In addition, the spherical salt obtained by this method is not a surface contact that comes from a tetragonal crystal like the conventional salt, but because it is spherical, the particles are in point contact with each other, so the texture is smooth and the fluidity is high. It became clear that it would be an excellent salt. The spherical salt of the present invention is hard to solidify even in a high humidity atmosphere, becomes a seasoning table salt that is easy to use with a good flow, and when it is used for funerals, it is free-flowing, so it can be easily removed, Does not stain clothes.
