Description

The present invention relates to a functional fine salt production apparatus for adding a functional raw material to the salt in the process of extracting the salt contained in the sea water by heating the sea water.

Recently, with increasing interest in health, functional salts, that is, salts in the form of salts containing various health promoting functional ingredients in general salt have been proposed.

In the production of such functional salt, first, salt concentrates such as seawater are filled in a separate tank, and the seawater is directly boiled and evaporated to generate general salts. Then, the salt is mixed with the liquid or powdered functional ingredients to be heated again. It is done through the process.

However, when the seawater is evaporated to prepare the initial salt, the heating takes place in the tank filled state. Therefore, the evaporation time of the seawater will take a long time, so the salt productivity is not high. Since there is a problem that must be carried out separately after the grinding process of salt.

In addition, since the process of mixing the functional ingredients after the salt production operation must be performed additionally, the time and manufacturing cost is increased accordingly, resulting in an increase in the unit cost of the product.

The present invention is to solve the problems of the prior art, to improve the heating method of seawater to improve the evaporation rate and to provide a functional fine salt production apparatus that can be produced in a state that does not need to undergo a separate grinding process.

In addition, to extract the salt from the salt concentrate in the process of extracting the functional ingredient contained in the state to provide a functional fine salt manufacturing apparatus that does not need to go through the process of mixing the additional functional ingredients.

The present invention having these various embodiments,

As the salt concentrate is supplied to the drying space in the form of fine particles through the concentrate spraying unit, and the concentrated particles are heated using hot air to remove moisture from each particle.

Since the heating is performed in the particulate state, the overall moisture evaporation speed is shortened compared to the existing ones, thereby improving the salt production rate.

In addition, since the concentrated liquid is evaporated in the particulate state, the salt generated from each particle is also in the fine particle state, and thus, there is no need to separately grind salt, thereby further improving productivity.

In addition, since the salt concentrate and the functional solution are sprayed in the mixed state by the mixing unit, the salt is produced in the state containing the functional ingredient at the same time as the water evaporation, so the process of mixing the salt and the functional ingredient does not need to be carried out separately. This also has the effect of being improved.

Hereinafter, with reference to the configuration illustrated in the drawings to explain an application example of the specific configuration of the present invention.

First, the same components or parts in the drawings use the same reference numerals as possible, and detailed descriptions of related known functions or configurations will be omitted in describing the present invention.

Functional fine salt production apparatus of the present invention is largely as shown in the [Fig. 1] and [Fig. 2] drying unit 100 and the raw material supply unit 200, the heating unit 300, the exhaust unit 400 and the transfer unit 500 It is configured to include.

First, the drying unit 100 is a part in which water evaporation of a salt concentrate (hereinafter, referred to as a 'concentrate') such as saltwater is performed. In other words, it has the same structure as a general storage tank.

And on one side is formed a raw material inlet 120 for the introduction of the concentrate, and the other side is formed with a heating inlet 130 for the introduction of hot air.

In addition, an exhaust port 140 for external discharge of steam generated in the drying space 110 during the heating process is formed at an upper portion thereof, and a salt outlet 150 for discharge of salt generated by evaporation of the concentrate is formed at a lower portion thereof.

Since the drying part 100 is in direct contact with the concentrate as mentioned above, plastic or brick may be used, and when metal is used, a material having a low risk of corrosion, such as stainless steel, may be used. By applying a material having excellent heat resistance or a material having excellent flame resistance, it is possible to prevent breakage due to heat or salt during the concentration heating process.

For reference, the drying unit 100 may be manufactured in a rectangular or spherical shape in addition to the cylindrical shape shown in the drawings.

The drying unit 100 is connected to the raw material supply unit 200,

The raw material supply unit 200 serves to supply the drying unit 100 in a state in which the concentrated solution and the separate functional solution before the evaporation process are mixed, and the functional solution supply unit 210 and the concentrate supply unit 220 are mixed again. The unit 230 and the compressed air supply unit 240 is configured.

For reference, the concentrate may be referred to as salt concentrate, brine concentrate or concentrated water, for example, seawater, seawater concentrate, salt-containing water, seawater, seawater concentrate concept is limited to these examples no.

The functional solution may include a plant extract such as garlic, green tea, seaweed, or water mixed with plant components, and may include a solution containing minerals or other chemical components such as minerals in addition to the plant components. The concept includes not only the solution but also all solutions containing other health promoting ingredients.

In addition, the 'mixture' referred to below means a salt concentrate containing a mixture of a concentrate and a functional solution, that is, a functional ingredient.

First, the functional solution supply unit 210 serves as a function of supplying a functional solution as the name, and serves as a movement path of the concentrated liquid discharged from the first storage tank 212 and the first storage tank 212 in which the functional solution is stored. One pipe 214 is included.

In addition, the concentrate supply unit 220 also functions to supply the concentrate as the name, and the second pipe serving as a movement path of the concentrate discharged from the second storage tank 222 and the second storage tank 222 where the concentrate is stored. And 224.

The first pipe 214 and the second pipe 224 are connected to the mixing unit 230 at the same time, the mixing unit 230 is the functionality discharged from the first storage tank 212 and the second storage tank 222. The mixing role of the solution and the concentrate, and further includes a mixing body 232 and the mixed discharge pipe 234.

The mixing body 232 is formed in a general storage tank shape as a whole, a mixing space 232a is formed therein, and the first and second pipes 214 and 224 are simultaneously connected to the side.

At this time, the inside of the mixing body 232 may be further provided with a stirrer 232b such as a stirring blade.

And the mixing discharge pipe 234 serves to supply the mixed solution between the functional solution and the concentrate mixed in the mixing body 232 to the drying space 110, one end is connected to the mixing body 232, the other end is the drying unit It is inserted into the raw material inlet 120 of (100).

For reference, although not shown in the drawings, the first and second pipes 214 and 224 and the mixed discharge pipe 234 may be directly connected so that the mixing may be performed in the process of moving the functional solution and the concentrate along each pipe.

In this case, if only sufficient mixing efficiency can be obtained, it is not necessary to provide the mixing body 232.

The compressed air supply unit 240 serves to discharge the mixed liquid discharged into the drying space 110 in a fine particle state, and is discharged from the air compressor 242 and the air compressor 242 which compress and discharge the air. It consists of an air supply pipe 244 which guides the compressed air to the concentrate supply pipe 234.

The air compressor 242 may be used as a general compressor, the air supply pipe 244 is one end is connected to the air compressor 242 and the other end is directly connected near the end of the mixed discharge pipe 234, the concentrate is discharged It may be mixed with the compressed air immediately before to be discharged in the form of fine particles.

Mixing between the compressed air and the mixed liquid may be performed using the injection nozzle 236 in addition to the direct connection structure between the mixed discharge pipe 234 and the air supply pipe 244.

In this case, it is possible to improve the structure of the injection nozzle 236 to improve the output power of the concentrate by mixing and air pressure.

The injection nozzle 236 used for this purpose is basically formed in a hollow tube shape as shown in FIG. 3, and an air inlet 236a is formed at one end and a discharge hole 236b having a relatively small diameter is formed at the other end. .

In this case, a cross-sectional reduction portion 236c having a reduced cross-sectional area is formed at an intermediate point of the inside of the injection nozzle 236, and a raw material inlet 236d is formed below the cross-sectional reduction portion 236c to have an overall 'venturi tube' structure.

The injection nozzle 236 is connected to the air supply pipe 244 to the air inlet 236a and the mixed discharge pipe 234 is connected to the raw material inlet 236d.

Therefore, when the compressed air passes through the section nozzle 236c while passing through the injection nozzle, the speed increases momentarily, and as a result, the corresponding pressure decreases, the mixed body having a relatively high pressure by Bernoulli's law (232) The mixed liquid inside is naturally sucked up into the injection nozzle 236 along the mixing discharge pipe 234, mixed with compressed air in the injection nozzle, and then discharged through the discharge port 236b.

For reference, in addition to the above method, the same phenomenon may occur even when the outlet of the air supply pipe 244 is adjacent to the outlet of the mixed discharge pipe 234, and the concentrated liquid is discharged, and at the same time, the compressed air can be scattered in the form of fine particles. .

If necessary, the air heater 250 may be connected to the air compressor 232 so that the compressed air is supplied to the injection nozzle 236 or the mixed discharge pipe 234 in a heated state.

In this case, since the concentrate is discharged in a sufficiently heated state, the evaporation efficiency by the heating unit (to be described later) may be further improved.

In this case, when the heating temperature of the compressed air is about 600 ° to 800 °, a high evaporation efficiency may be obtained. Of course, the heating temperature is not limited thereto and may be variously modified according to the amount of concentrated water discharged.

The heating part 300 is installed at the other side of the drying part 100 to which the mixing discharge pipe 234 is connected.

The heating unit 300 serves to separate the water and the salt by heating the mixed liquid discharged from the raw material supply unit 200, and again includes a heating blower 310 and a blowing duct 320.

The heating blower 310 serves to generate and supply hot air and has a general blower structure, but a heater 312 is provided therein to discharge the air in a heated state.

The blower duct 320 connected to the heating blower 310 has a hot air outlet connected to the heating inlet 130 of the drying unit 100 so that the heated air flows into the drying space 110.

At this time, the hot air discharge pressure of the heating unit 300 is to be formed almost the same as the mixed liquid discharge pressure of the raw material supply unit 200, the reason is mentioned in the operation description process below. In addition, the output of the heating unit 300 and the raw material supply unit 200 may be variously modified according to the storage capacity of the drying unit 100.

For reference, the heating unit 300 may be implemented in a burner form in addition to the hot air generating structure, and may be directly installed in the drying space 110 of the drying unit 100 by being implemented as an electric heater structure.

If the air compressor 250 is connected to the air compressor 232, the air supply pipe 224 is distributed, and one air supply pipe is connected to the mixed discharge pipe (), and the other air supply pipe is the drying unit 100. It may be connected to the heating inlet 130 of.

That is to say that the air compressor 232 and the air heater 250 can be parallel to the heating unit 300 function. Therefore, in this case, the heating unit 300 does not need to be separately installed.

The exhaust unit 400 is connected to the upper side of the drying unit 100 installed up to the heating unit 300.

The exhaust unit 400 is to increase the separation efficiency between salt and water by discharging the steam generated by the evaporation of the concentrate in the drying space 110 to the outside, and consists of an intake apparatus 410 and an exhaust duct 420.

The intake apparatus 410 has a structure opposite to that of the heating blower 310, that is, an intake fan structure for sucking air, and the exhaust duct 420 has one end connected to the intake port of the intake apparatus 410 and the other end being a drying unit. It is connected to the exhaust port 140 of the (100).

In addition, if necessary, a separate dust collecting structure may be applied to the intake apparatus 410 to allow external discharge to be carried out in a state in which foreign substances contained in the steam are filtered out.

At this time, the intake output of the intake apparatus 410 should be set so as to suck moisture, that is, water vapor during the evaporation of the concentrate, to prevent the phenomenon that the generated salt is sucked out and lost together.

The transfer unit 500 is installed below the drying unit 100 connected to the exhaust unit 400.

The transfer part 500 serves to transfer the salt generated and discharged in the drying part 100 to a packaging or other post process, and is made of a general conveying conveyor structure and is below the salt outlet 150 of the drying part 100. Is located in.

The following describes the overall operation of the present invention by this configuration and the unique effects generated in the process.

As shown in FIG. 2, the functional solution stored in the first tank 212 is supplied into the mixing body 232 along the first pipe 214, and the concentrated liquid stored in the second tank 222 is connected to the second pipe ( 224 is supplied into the mixing body 232.

Therefore, the mixture is naturally mixed in the mixing body 232 or mixed by a separate stirrer 232a to produce a mixed solution, that is, a salt concentrate containing a functional component.

In addition, the compressed air discharged from the air compressor 242 moves along the air supply pipe 244 and flows into the vicinity of the outlet of the mixed discharge pipe 234, and the drying space 110 of the drying unit 100 through the mixed discharge pipe 234. Is discharged.

At this time, since the compressed air supplied to the mixed discharge pipe 234 has a high moving speed, the pressure of the discharge point of the mixed discharge pipe 234 is lowered, and the mixed liquid in the mixed body 232 is naturally mixed discharge pipe () by such a pressure change. Is moved along.

Therefore, the mixed liquid and the compressed air are mixed in the mixed discharge pipe 234 and then discharged.

As the mixed liquid is discharged in a mixed state with the compressed air, it is dispersed together with the compressed air at the moment of discharge, and is dispersed and discharged in the form of fine particles as if it was sprayed through an atomizer.

At the same time, the hot air generated from the heating unit 300 is supplied through the heating inlet 130 of the drying unit 100, and the supplied hot air and the mixed liquid particles collide in the drying space 110 to evaporate the moisture of each particle. This is done.

At this time, the evaporated water includes both the water contained in the concentrate and the water contained in the functional solution.

In this way, the salts, ie, salts and functional components, contained in each mixed liquid particle are extracted, and the functional components are coated on the salt surface or contained inside during heating.

That is, salt particles containing functional ingredients are produced.

In this way, the mixed solution is sprayed in the form of fine particles, so that the individual heating is performed for each particle, so that not only the evaporation of the entire concentrate is much faster than before, but also fine salt particles containing functional ingredients are produced.

In addition, when the air compressor 250 is provided in the air compressor 242 as mentioned above, the even evaporation efficiency is further improved because the mixed liquid is discharged in a sufficiently heated state to be in contact with the hot air.

Thus, water and functional salts are separated by moisture evaporation, and at the same time, due to mutual specific gravity, water is discharged through the exhaust port 140 by the operation of the exhaust unit 400, and the functional salt naturally falls downward.

As mentioned above, as the evaporation rate is increased by spraying the fine particles of the concentrate, the production speed of the functional salt is also improved, so the overall production efficiency is improved, and it is produced as the fine particles containing the functional ingredients in the salt. There is no need to go through ingredient mixing.

The functional salt dropped down like this is discharged to the outside through the salt discharge port 150 and then transported to one side by the transfer unit 500 is collected.

As this process is carried out continuously, the production of functional salt is continuous and continuous. Although the amount of the functional salt produced instantaneously is smaller than that of the conventional catchment heating method, the final output is continuously generated at the same time as the heating. Much more.

For reference, before the spraying of the mixed liquid, the heating part 400 is used to sufficiently heat the inside of the drying space 110 to form a sufficient heating atmosphere. Thus, the evaporation effect is further increased compared to the case where the evaporation is performed purely by hot air at room temperature. It can be increased.

4 is a view showing a modified example of the present invention, the present embodiment is the same as the previous embodiment, the overall configuration, but is an example for further increasing the evaporation effect by changing the structure of the drying unit 100.

Specifically, the first drying unit 100a having the first drying space 100a-1 formed therein by implementing the drying unit 100 in the form of a multi-pipe is installed in the first drying space 100a-1. The second drying unit 100b is installed to have a structure in which the second drying space 100b-1 is formed in the second drying unit 100b.

At this time, the area of the first drying space 100a-1 is sufficiently formed around the second drying unit 100b so that the evaporation in the first drying space 100a-1 can be sufficiently performed.

At this time, the through-hole (100b-2) is formed in the second drying unit (100b) has a structure in which the second drying space (100b-1) and the first drying space (100a-1) communicate with each other.

The injection nozzle 236a added to the raw material supply unit 200 and the hot air duct 320a added to the heating unit 300 are respectively provided in the first drying space 100a-1 and the second drying space 100b-1. Connected.

Explaining the working process of this variant,

When the hot air and the concentrate are supplied to the first drying space (100a-1) and the second drying space (100b-1) in the same manner as in the previous embodiment, the first drying space (100a-1) and the second drying space ( 100b-1) is evaporated throughout, and the steam generated in the second drying space 100b-1 is discharged to the first drying space 100a-1 through the through hole 100b-2 and then discharged to the exhaust port. .

At this time, as the independent space is newly formed in the second drying space (100b-1), the exhaust time of the entire steam is inevitably delayed, and as a result, the heating time of the steam is increased accordingly, and thus up to the fine salt contained in the steam. It will have an extractable effect.

Although the structure of the drying unit is complicated compared with the previous embodiment, the salt production efficiency is higher.

For reference, in this structure, a drying unit may be additionally provided in addition to the second drying unit 100b. In this case, salt productivity may be further increased by the aforementioned principle.

In addition, the structure of the second drying unit 100b is not limited to the multi-tubular shape, and may be modified into a structure such as being separately installed outside the first drying unit.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided.
