Among the powdered foods used in the diet, there are powdered red pepper powder, perilla powder, sesame powder, rice flour, soybean flour, flour and garlic powder. Among the drift ingredients, there are red pepper powder, .

These powdered and drifted ingredients are dried for a predetermined period of time before the powder and the slices are formed, and are then subjected to a process of making them into a dry material, and the dried ingredients are subjected to a grinding process or a cutting process. Crushed or cut foodstuffs are supplied to consumers through packaging.

Such conventional methods for drying powders and drift food materials have two problems.

First, it takes a long time to dry powdery and drifted food materials in a conventional dryer, and the drying is not ensured.

Of course, drying in a dryer rather than drying in a dry condition may help to shorten the drying time. However, since the drying time is delayed due to the inability to smoothly process the moisture generated during drying, the heat transferred to the food is not constant, It will not dry out evenly.

Second, the dried ingredients are discharged from the dryer and then packaged. Most of the foodstuffs are infected with bacteria during the drying and transporting and packaging processes.

HACCP has become the standard of manufacturing process as a countermeasure to prevent harmful substances from entering food related production. However, HACCP is only for the maintenance of the environment and facilities of the factory, and it is a helpless for the contamination of airborne viruses, such as contamination by raw materials, contamination by air in facilities, and transportation between facilities and facilities.

Therefore, it is possible to produce and supply hygienically safe foodstuffs by implementing the whole process from food sterilization, drying, transportation and packaging to one system, The method is desperately needed. In other words, there is an urgent need for a method that can safely provide food to consumers without sacrificing the quality of the produced foodstuffs, thereby securing food and hygiene safety of consumers.

The high-temperature, high-pressure steam passes through the nozzle 61 of the gas spraying unit 60, forms a vortex, and is spouted upward while swirling.

The reason why the inside of the sterilizing and drying unit 10 is subjected to the vacuum treatment when the raw material is sterilized by the sterilizing unit 80 is that the purpose is to rapidly and uniformly spread the high temperature steam introduced into the sterilizing and drying unit 10 have.

When the internal temperature of the sterilizing and drying unit 10 reaches 80 DEG C by operating the sterilizing unit 80, the vacuum pump is stopped. When the vacuum pump is stopped, the internal pressure of the sterilizing and drying unit 10 is increased, and damage to the vacuum pump is prevented by the high temperature.

In addition, the inside of the sterilizing and drying unit 10 must be pressurized before the water is boiled. When the water boils, the moisture in the raw material cells is vaporized, which damages the cell membrane, resulting in defects in quality. Therefore, when the internal temperature of the sterilizing and drying unit 10 reaches 80 DEG C, stopping the pump can prevent the boiling point of the introduced water from becoming too low. When the internal temperature of the sterilizing / drying unit 10 reaches 100 to 250 ° C, the steam supply to the sterilizing unit 80 is stopped.

A dust layer 92 is provided on the bottom surface of the upper plate 13 so as to filter the raw material contained in the air when the air inside the sterilizing and drying section 10 flows into the vacuum suction port 91 of the vacuum processing section 90.

The air inside the sterilizing / drying unit 10 contains raw material dust. When the dust is introduced into the vacuum pump as the vacuum processing unit 90 through the vacuum suction port 91, the vacuum pump breaks down and the raw material is lost . Therefore, a dust layer 92 is provided around the vacuum suction port 91 located inside the sterilizing and drying unit 10 to filter the dust of the raw material contained in the air.

The gas supplying unit 100 is connected to the gas injecting unit 60 to supply the high pressure gas into the sterilizing and drying unit 10 and to lower the internal temperature of the sterilizing and drying unit 10 raised by the high pressure steam injection .

When the internal temperature is lowered to 80 DEG C or lower by the gas supply, the vacuum pump of the vacuum processing unit 90 is operated. The internal temperature of the sterilizing and drying unit 10 is lowered more rapidly by the operation of the vacuum pump. At this time, the internal pressure of the sterilizing / drying unit 10 is not lowered more than the atmospheric pressure because the operation of the vacuum pump and the gas supply are performed at the same time.

The drying unit 110 heats the sterilizing / drying unit 10 installed in the sterilizing / drying unit 10 and cooled by the gas supplying unit 100 to raise the temperature inside thereof, thereby drying the raw material.

The drying unit 110 includes a heater 111 installed around the sterilizing and drying unit 10 to heat the sterilizing and drying unit 10 and a heater 111 installed around the sterilizing and drying unit 10 A heater holder 112 supported on the periphery of the sterilizing and drying section 10 and a heater 112 installed around the sterilizing and drying section 10 to finish the entire periphery of the heater 111 and the heater holder 112 and the sterilizing / And the heat insulating material 113 is formed.

When the internal temperature of the sterilizing and drying unit 10 is lowered to the lower limit temperature (40 ° C) by the gas supplying unit 100, the gas supply is stopped and the heater 111 of the drying unit 110 is operated. And the pumping capacity of the vacuum pump is maximized.

When the temperature of the sterilizing and drying section 10 is raised by the heater 111 and reaches the upper limit temperature (45 캜), the heater 111 is turned off and only the vacuum pump is operated. If the upper limit temperature is high, the drying time is shortened, but the color of the raw material may be changed.

After about 5 minutes has elapsed, the gas injection is started and cooled. When the internal temperature reaches the lower limit temperature, the gas injection is stopped and the heater 111 is operated to heat the sterilizing and drying unit 10 again.

The humidity of the raw material is lowered by repeating this process. The humidity of the sterilizing and drying unit 10 is measured using a hygrometer, and heating and cooling are repeated until a desired level of drying is achieved.

When the degree of vacuum is increased, the vaporization point of water is lowered, thereby inducing the evaporation of water, and the vaporized moisture is discharged out by supplying the low temperature and dry gas from time to time. The supply of gas causes a powerful whirlwind to prevent the raw materials from being bunched together.

The storage tank 120 is connected to the outlet of the sterilizing and drying unit 10, and pasteurized, dried powder and drift food are supplied. The storage tank 120 is provided with an upper engagement flange 121, and the anti-scattering portion is coupled to the upper engagement flange 121.

When drying with the humidity set by the sterilizing and drying unit 10 is completed, the heater 111, the vacuum pump, and the gas injection are stopped.

Then, the opening / closing part 70 at the lower end of the sterilizing / drying unit 10 is opened and gas is introduced from the upper part.

At this time, the storage tank 120 is installed below the sterilizing and drying unit 10, and the connecting portions of the sterilizing and drying unit 10 and the storage tank 120 are sealed by the scattering prevention unit 130, Is prevented from being contaminated.

The reason for introducing the gas into the sterilizing and drying unit 10 when the opening and closing unit 70 is opened is that the purified gas is introduced into the inner space of the sterilizing and drying unit 10 generated while the raw material is discharged, The purpose is to block any inhalation. When the raw material is discharged, the gas supplied into the sterilizing and drying unit 10 acts to push the raw material toward the storage tank 120, thereby smoothly discharging the raw material.

The scattering prevention part 130 is installed between the sterilizing and drying part 10 and the storage tank 120 and is disposed around the sterilization and drying part 10 when the sterilized and dried raw material is put into the storage tank 120 Block scattering and prevent contact with external contaminants.

The scattering prevention part 130 is disposed between the sterilizing and drying part 10 and the storage tank 120 and includes a bellows pipe 131 for absorbing the flow generated in the sterilizing and drying part 10 and the storage tank 120, An upper flange 132 provided at the upper and lower ends of the bellows pipe 131 and coupled to the lower fitting flange 11 of the sterilizing and drying unit 10 and the upper fitting flange 121 of the storage tank 120, A lower flange 133 and a fastening bolt 134 and a fastening nut 135 which are fastened to the lower flange 11, the upper flange 132 and the upper flange 121, and the lower flange 133.

In addition, the agitating unit 30 is continuously operated until the raw material is charged, sterilized, dried and discharged, thereby guiding the raw materials in the sterilizing and drying unit 10 to be sterilized and dried and discharged uniformly. The agitating unit 30 serves to circulate the air inside the sterilizing and drying unit 10 and thus plays an additional role in maintaining the temperature inside the sterilizing and drying unit 10 uniformly within a short period of time.

The transfer unit 140 is connected to the storage tank 120 and transfers the ingredients in the storage tank 120. The transfer unit 140 includes a pair of brushes 141 and a conveyor 142 disposed under the brush 141.

The brush 141 is installed in a transfer passage on the lower side inside the storage tank 120, and the pair of brushes 141 are rotated in different directions and serve to break the raw materials. The raw material having passed through the brush 141 is supplied to the conveyor 142 below the brush 141 and supplied to the packaging unit 150 by the conveyer 142.

Here, the conveyor 142 may be a conveying screw that is long along the conveying passage. When the conveying screw is rotated, a wing formed in the form of a spiral around the conveying screw conveys the raw material dropped toward the conveying screw to the packing unit 150 side .

The packaging unit 150 is connected to the transfer unit 140 and supplies the ingredients in the storage tank 120 and packages the supplied ingredients.

The storage tank 120 and the transfer unit 140 and the packing unit 150 are hermetically closed so that the raw material is transferred from the storage tank 120 to the transfer unit 140 and transferred from the transfer unit 140 to the packaging unit 150 It is blocked from the outside.

The packaging unit 150 is made up of an automatic packaging machine for automatically wrapping the raw materials. The automatic packaging machine is such that when the plastic bag into which the raw material is to be introduced is opened and the raw material is put into the opened plastic bag, nitrogen, And performs a function of thermally fusing the inlet in the state that the raw materials and the introduction of gas such as nitrogen and carbon dioxide are completed, and any of the known automatic packing machines may be used as long as the automatic packing machine has such a function .

The controller 160 controls the motor 40 of the agitator 30, the water splasher 50, the gas injector 60, the sterilizer 80, the vacuum processor 90, the gas supplier 100, The transfer unit 110, the transfer unit 140, and the package unit 150 to control them.

The powdery and dried food sterilizing dryer of the present invention having such a configuration is sterilized, dried and packaged through the following steps.

First, there is a raw material charging step (S10) of putting the raw material in the raw material tank 1 into the sterilizing and drying unit 10 through the raw material charging opening 2.

When the raw material is supplied, the raw material inlet (2) is closed and the top plate locking portion (20) is operated. When the hydraulic cylinder 21 of the upper plate locking portion 20 is operated, the cylinder rod 22 is lowered and the pressing piece 23 is lowered along the guide 24 to move the upper plate 13 to the sterilizing and drying portion 10 And the sterilizing and drying unit 10 is sealed by pressing it on the upper plate flange 12.

When the sterilizing and drying unit 10 is closed after the raw material is inserted, the agitating unit 30 is operated to mix the raw materials so that the raw materials are uniformly injected into the space of the sterilizing and drying unit 10 and the raw materials are uniformly sterilized S20.

When the motor 40 of the stirring section 30 is driven, the stirrer shaft 31, the stirring assist shaft 32, the stirring wing 33, and the buffer section 34 are rotated together with the motor shaft 41. At this time, the vibrator 44 is also driven so that the vibrator shaft 31 vibrates in the vertical direction, and the buffer spring 39 of the cushioning portion 34 absorbs and cancels vibration generated in the vibrator shaft 31, To the nozzle 61 of the gas spraying unit 60 is minimized.

And a water spraying step (S30) for spraying water on the raw material when the raw material is charged and the agitating part (30) is driven to prevent scattering of the dust and damage of the raw material due to high temperature.

Water supplied from the water splasher 50 to the water supply port 51 is sprayed into the sterilizing and drying unit 10 through an injection nozzle (not shown). Since the stirring portion 30 is continuously driven while the water is sprayed, the water to be sprayed is uniformly sprayed over the entire raw material.

The reason for spraying the water before disinfecting the raw materials is as follows. If the raw material does not contain enough moisture and heat is applied, the color of the raw material will change if it exceeds a certain temperature. In order to prevent such color change, the raw material is sufficiently sprayed with water before the raw material is heated so that the raw material particles absorb the moisture sufficiently. Raw material particles sufficiently containing moisture are not changed in color even when the temperature exceeds 100 캜.

In addition, strong vortex is generated by the gas injector 60 during the sterilization process and the drying process, and the generation of dust is prevented by the water to be sprayed.

And a sterilizing step S40 for sterilizing the raw material by injecting high-temperature and high-pressure steam into the sterilizing and drying unit 10 by operating the gas spraying unit 60 when the raw material is charged.

The vacuum processing unit 90 connected to the upper side of the sterilizing and drying unit 10 is operated and the gas supply unit 100 installed at the lower part of the sterilizing and drying unit 10 is operated to sterilize the sterilizing and drying unit 10 ) It causes a strong whirlwind inside. The reason why the vacuum pump is operated while injecting the high-temperature and high-pressure steam in the nozzle 61 is that the high-temperature heat is rapidly diffused throughout the raw material.

When the internal temperature of the sterilizing / drying unit 10 reaches 80 ° C, the vacuum processing unit 90 is stopped, and the inside of the sterilizing / drying unit 10 is heated by the high temperature and high pressure steam, Is increased.

When the temperature inside the sterilizing / drying unit 10 reaches 100 to 250 ° C, the steam supply is stopped. Bacteria and viruses that penetrate raw materials are completely sterilized by high temperature steam of 100 ~ 250 ℃ and high pressure of 1.0 ~ 2.5 times.

If the internal temperature of the sterilizing and drying unit 10 is less than 100 ° C, sterilization can not be performed properly. If the internal temperature of the sterilizing and drying unit 10 exceeds 250 ° C, the raw materials such as color change of the raw materials may be damaged. Therefore, it is preferable that the sterilizing temperature of the sterilizing and drying unit 10 is maintained at 100 to 250 ° C.

After the sterilizing treatment, the supply of the high temperature and high pressure steam is stopped, the air inside the sterilizing and drying unit 10 is discharged to the outside, and the outside air is supplied into the sterilizing and drying unit 10 to lower the temperature inside the sterilizing and drying unit 10 (S50).

After the sterilizing step S40 is performed for a predetermined time (several seconds to 20 minutes), the solenoid valve 15 is operated to open the high-temperature high-pressure steam outlet 14 to lower the internal pressure of the sterilizing and drying unit 10, (100) is driven to spray a low-temperature, dry gas. The low temperature and dry gas supplied to the nozzle 61 of the gas spraying unit 60 through the gas supply port 101 passes through the air injection hole 62 of the nozzle 61 and vortexes are formed and sprayed. Spread.

When the temperature inside the sterilizing and drying section 10 is lowered to 80 캜 or less by the supply of the low temperature and dry gas, the vacuum pump 90 serving as the vacuum processing section 90 is operated to quickly discharge the air inside the sterilizing and drying section 10 to the outside .

The internal temperature of the sterilizing and drying unit 10 is lowered more rapidly because the vacuum pump is operated and the air inside the sterilizing and drying unit 10 is discharged by the vacuum pump. The pressure change inside the sterilizing and drying unit 10 does not occur.

When the inside of the sterilizing and drying unit 10 is cooled in the rapid cooling step S50, the heater 111 is operated to heat the sterilizing and drying unit 10 to discharge the moisture evaporated from the raw material to the outside, And drying the raw material by repeating the process of feeding the raw material into the drying chamber 10 (S60).

In the drying step S60, when the inside of the sterilizing and drying unit 10 is cooled to 40 캜, the supply of gas to the gas supplying unit 100 is stopped, the heater 111 around the sterilizing and drying unit 10 is operated, The inside of the sterilizing and drying unit 10 is heated and the vacuum pump 90, which is the vacuum processing unit 90, is operated to discharge the moisture inside the sterilizing and drying unit 10 to the outside. When the internal temperature of the sterilizing and drying section 10 reaches 45 캜, the heater 111 is turned off and only the vacuum pump is operated. After 5 minutes have elapsed, the gas supplying section 100 is operated, And when the internal temperature of the sterilizing and drying unit 10 reaches 40 캜, the gas supplying unit 100 is stopped and the heater 111 is operated to heat the interior.

A storage tank transferring step of transferring the dried raw material inside the sterilizing and drying unit 10 to the storage tank 120 by opening and closing the opening and closing part 70 of the sterilizing and drying unit 10 by operating the opening and closing unit 70 after the drying step S60 (S70).

The external gas is introduced into the sterilizing / drying unit 10 through the gas supply port 101 provided at the top of the sterilizing / drying unit 10 in the storage tank transfer step S70, The discharge speed is increased while being pushed toward the opening / closing part 70 by the introduced external gas.

And an automatic packaging step (S80) in which the raw material is transported to the storage tank (120) and then transported to the packaging unit (150) and vacuum-packed.

The disinfection dryer of the powder type and the drift food material of the present invention has the following advantages.

First, the present invention is carried out in an enclosed system in which raw material input, sterilization, drying, storage, transfer, and packaging processes are shut off from the outside.

Therefore, it is possible to produce and supply hygienic and safe food materials by blocking infiltration of germs and viruses that can flow in the process of transportation between processes.

Secondly, in the present invention, the vibrator 44 is installed on the agitator shaft 31 in the agitator 30.

Therefore, the agitator shaft 31 is vibrated up and down by the vibrator 44 provided on the agitator 30, so that the agitator shaft 31 and the agitator 33 are rotated in the horizontal direction and vibrated in the axial direction The raw material is surely prevented from being kneaded and the heat inside the sterilizing and drying unit 10 is spread evenly.

Thirdly, at the lower end of the stirrer shaft 31 of the present invention, a buffer part 34 for supporting the stirring part 30 is provided. The buffer part 34 is installed at the lower end of the stirrer shaft 31 A supporting shaft 35 for supporting the stirrer shaft 31 with the lower end thereof contacting the gas injector 60 and a supporting shaft 35 coupled to the lower end of the stirrer shaft 31 and the upper end of the supporting shaft 35 A hinge pin 37 which engages with the stirrer shaft 31 and a hinge pin 37 which is provided between the stirrer shaft 31 and the support shaft 35 so that the lower end of the support shaft 35 is elastically supported by the gas injector 60 And a cushion spring 39 for preventing the impact transmitted to the agitator shaft 31 from being transmitted to the gas ejection unit 60. A curved surface 36 having an outward convex shape is formed at the lower end of the support shaft 35 .

Therefore, when the stirrer shaft 31 is vibrated in the axial direction by the vibrator 44, the curved surface 36 of the support shaft 35 stably contacts the shaft support groove 63 of the nozzle 61, The shock due to the flow of the shaft 31 is canceled by the buffer spring 39 so that the vibration of the agitator shaft 31 is minimized to the nozzle 61 so that damage to the nozzle 61 is prevented.

Fourthly, in the gas injector 60 of the present invention, the air injected from the air injection holes 62 is provided to form a vortex while being rotated in a clockwise direction, and the air injection direction of the plurality of air injection holes 62 is And is arranged to face the nozzle 61 in the clockwise direction with respect to the plane of the nozzle 61. The spray angle of the air injection hole 62 is arranged to face upward when viewed from the front face of the nozzle 61. [

Therefore, the air injection holes 62 are arranged on all four sides of the nozzles 61, the air injection directions thereof are arranged to face clockwise, and the air injection holes 62 are oriented upward at an angle of 45 ° with respect to the front surface of the nozzles 61 The gas is spirally blown upward in the sterilizing and drying unit 10. Therefore, since it is sprayed while swirling in the upward direction, it diffuses into the sterilizing and drying unit 10 and is uniformly permeated into the raw materials.

Fifth, when the sterilized and dried raw material is put into the storage tank 120 from the sterilizing and drying unit 10, it is prevented from scattering around the sterilization and drying unit 10 and the storage tank 120, A scattering preventing portion 130 in the form of a bellows tube is provided so as to block contact with contaminants.

Accordingly, when the sterilized and dried raw material is introduced into the storage tank 120, the powdery raw material is prevented from scattering to the outside, and foreign contaminants are prevented from flowing into the raw material.

Sixth, since the scattering prevention part 130 of the present invention is formed in the form of a bellows tube, the gap between the sterilizing and drying part 10 and the storage tank 120 is smoothly adjusted.

Accordingly, even if the vertical interval between the sterilizing and drying unit 10 and the storage tank 120 is not constant depending on the capacity of the disinfection and drying apparatus to be installed, it can be properly compensated for and thus, the compatibility is excellent.

The sterilizing and drying unit 10 of the present invention is provided with a sterilizing and drying unit 10 that presses the upper plate 13 seated on the upper surface of the sterilizing and drying unit 10 against the upper plate flange 12 of the sterilizing and drying unit 10, And an upper plate locking portion 20 for sealing the inside is provided.

When the hydraulic cylinder 21 is operated and the cylinder rod 22 is lowered, the pushing piece 23 is lowered along the guide 24 and the upper plate 13 is moved to the upper plate flange 12 of the sterilizing and drying unit 10 So that the inside of the sterilizing and drying unit 10 is sealed. Therefore, since the sterilizing and drying unit 10 is automatically opened and closed under the control of the hydraulic cylinder 21, the opening and closing operation of the sterilizing and drying unit 10 is very simple.

Eighth, the present invention has a sterilizing step (S40) for sterilizing the raw material by injecting steam of high temperature and high pressure into the sterilizing and drying unit (10) by operating the gas spraying unit (60) S40), the vacuum pump of the vacuum processing unit 90 is operated to vacuum-process the inside of the sterilizing and drying unit 10. [

Accordingly, since the inside of the sterilizing and drying unit 10 is vacuum-treated, the high-temperature steam supplied from the lower portion of the sterilizing and drying unit 10 to the inside of the sterilizing and drying unit 10 is smoothly diffused into the vacuum sterilization and drying unit 10 , So that the high-temperature steam spreads evenly over the raw material within a short period of time, so that the entire raw material is uniformly heated and sterilized in a short time.

Ninthly, the present invention has a drying step (S60) when the inside of the sterilizing and drying part (10) is cooled through the rapid cooling step (S50). In this drying step (S60) The heater 111 around the sterilizing and drying unit 10 is operated to heat the inside of the sterilizing and drying unit 10 and the vacuum pump is operated to sterilize the sterilizing and drying unit 10, When the internal temperature of the sterilizing and drying unit 10 reaches 45 캜, the heater 111 is turned off and only the vacuum pump is operated.

After 5 minutes from the operation of the vacuum pump, the gas supply unit 100 is operated to supply the low temperature dried gas to the inside of the sterilizing and drying unit 10. When the internal temperature of the sterilizing and drying unit 10 reaches 40 ° C, (100) is stopped and the heater (111) is operated to heat the interior.

Accordingly, the internal heating of the sterilizing and drying unit 10, the moisture discharge, the internal vacuum treatment of the sterilizing and drying unit 10, and the charging process of the low temperature drying gas are repeated, and the moisture contained in the raw material is discharged to the outside. Therefore, the moisture contained in the entire raw material is discharged to the outside of the moved part quickly and reliably by the air inside the sterilizing / drying unit 10, so that the drying time is greatly shortened and the entire raw material is evenly dried.

In the tenth aspect of the present invention, when the raw material is charged into the sterilizing and drying unit 10, the raw material is mixed with the agitating unit 30 and water is sprayed onto the raw material by the water dispersing unit 50.

Therefore, since water is sprayed onto the raw material in powder form, dust is prevented from scattering when agitated by the agitating part 30. In addition, even if the raw material is heated to a high temperature in order to sterilize the raw material, the raw material is instantly prevented from burning due to the heat of high temperature.

On the other hand, a wear-resistant coating layer may be formed on the support shaft 35 of the buffer part 34.

Here, the abrasion-proof coating layer is formed by spraying a powder composed of 96 to 98% by weight of chromium oxide (Cr ₂ O ₃ ) and ₂ to 4% by weight of titanium dioxide (TiO ₂ ) onto the support shaft 35, And the hardness is plasma-coated to maintain 900 to 1000 HV.

The wear-resistant coating layer is formed by spraying powder composed of 96 to 98% by weight of chromium oxide (Cr ₂ O ₃ ) and ₂ to 4% by weight of titanium dioxide (TiO ₂ ).

The reason why the ceramic coating is applied to the outer circumferential surface of the support shaft 35 is to prevent abrasion and corrosion. Compared to chrome plating or nickel chrome plating, the ceramic coating is excellent in corrosion resistance, scratch resistance, abrasion resistance, impact resistance and durability.

Chromium oxide (Cr ₂ O ₃ ) acts as a passivity layer to block oxygen entering the inside of the metal, thereby preventing rusting.

Titanium dioxide (TiO ₂ ) is a white pigment because it is very stable physicochemically and has high hiding power. And is also widely used for ceramics having high refractive index because of high refractive index. And has characteristics of photocatalytic property and superhydrophilic property. Titanium dioxide (TiO ₂ ) acts as an air purification function, an antibacterial function, a harmful substance decomposition function, a pollution prevention function, and a discoloration prevention function. This titanium dioxide (TiO ₂ ) ensures that the wear-resistant coating layer is coated on the outer circumferential surface of the support shaft 35 and dissolves and removes the foreign matter adhering to the wear-resistant coating layer to prevent the wear-resistant coating layer from being damaged.

Here, chromium oxide (Cr ₂ O ₃₎ and when using hayeoseo mixing titanium dioxide (TiO _2), the mixing ratio of these, chrome oxide (Cr ₂ O ₃₎ Titanium dioxide (TiO ₂₎ in 96-98% by weight 2 By weight to 4% by weight.

When the mixing ratio of chromium oxide (Cr ₂ O ₃ ) is less than 96 to 98%, the covering of chromium oxide (Cr ₂ O ₃ ) is often broken in an environment of high temperature and the like, ) The rust prevention effect of the outer circumferential surface was decreased suddenly.

When the mixing ratio of titanium dioxide (TiO ₂ ) is less than 2 to 4 wt%, the effect of titanium dioxide (TiO ₂ ) is insignificant so that the purpose of mixing it with chromium oxide (Cr ₂ O ₃ ) is discolored. That is, titanium dioxide (TiO ₂ ) is used to dissolve and remove foreign matter adhered to the outer circumferential surface of the support shaft 35 to prevent corrosion or damage to the outer circumferential surface of the support shaft 35, %, There is a problem that it takes much time to decompose the attached foreign matter.

The coating layer made of these materials is plasma-coated to have a thickness of 50 to 600 mu m around the outer peripheral surface of the support shaft 35, a hardness of 900 to 1000 HV, and a surface roughness of 0.1 to 0.3 mu m.

The wear-resistant coating layer is sprayed by spraying the above-described powdered powder and gas at 1400 DEG C around the outer peripheral surface of the support shaft 35 at a Mach 2 speed to 50 to 600 mu m.

If the thickness of the wear-resistant coating layer is less than 50 탆, the above-mentioned effect of the ceramic coating layer can not be guaranteed. If the thickness of the wear-resistant coating layer exceeds 600 탆, the above- There is a problem that working time and material cost are wasted.

The temperature of the outer circumferential surface of the support shaft 35 is raised while the wear prevention coating layer is coated on the outer circumferential surface of the support shaft 35. In order to prevent the outer circumferential surface of the heated support shaft 35 from being deformed, Cooled by a cooling device (not shown) to maintain a temperature of 150 to 200 ° C.

A sealing material made of anhydrous chromic acid (CrO ₃ ) made of a metal-based glass quartz system may further be applied to the periphery of the abrasion-resistant coating layer. Anhydrous chromic acid is applied as an inorganic sealing material around a coating layer made of chromium nickel powder.

Anhydrous chromic acid (CrO ₃ ) is used in places that require high abrasion resistance, lubricity, heat resistance, corrosion resistance and releasability, is not discolored in the atmosphere, has high durability, and has good abrasion resistance and corrosion resistance. The coating thickness of the sealing material is preferably about 0.3 to 0.5 mu m. If the coating thickness of the sealing material is less than 0.3 占 퐉, the sealing material easily peels off even in a slight scratch groove, so that the above-mentioned effect can not be obtained. If the coating thickness of the sealing material is made thick enough to exceed 0.5 탆, pin holes, cracks, and the like will increase on the plated surface. Therefore, the coating thickness of the sealing material is preferably about 0.3 to 0.5 mu m.

Therefore, since the coating layer having excellent abrasion resistance and oxidation resistance is formed around the outer circumferential surface of the support shaft 35, the outer circumferential surface of the support shaft 35 is prevented from being worn or oxidized, thereby extending the service life of the product.

In addition, the cyclone nozzle 170 may be coupled to the water supply port 51 of the water splasher 50 as shown in FIG.

The upper end of the cyclone nozzle 170 is provided with a male screw portion 171 having a screw thread to be fastened to the water supply hole 51, A body portion 172 having a hollow shape and a conical shape is integrally formed to extend downwardly from the body portion 172. A plurality of injection holes 173 through which air is finally injected along the spiral direction are passed through the body portion 172, .

A spiral water movement guide groove 174 coinciding with the injection hole 173 arranged in the spiral direction is formed on the outer surface of the body portion 172. The water movement guide groove 174 is formed in the injection hole 173, And guides the spraying direction of the water sprayed from the spraying nozzle to form a spiral.

Water sprayed through the injection hole 173 of the cyclone nozzle 170 and the spiral water movement guide groove 174 is sprayed into the sterilizing and drying section 10 while rotating and forming a swirl, (10).

14 is a partially enlarged sectional view showing the reverse rotation brake washer 180. As shown in Fig.
