Description

Colostrum Sterilizer with UV Module {COLOSTRUM STERILIZER EQUIPPED WITH UV MODULE}

The present invention relates to a milk sterilization device, and more particularly, colostrum sterilization device equipped with a UV module that can perform sterilization by mounting a UV module on a rotating impeller and supplying power to the UV module using a slip ring is about

Freshly squeezed milk from cows may be nutritionally the best, but raw milk without pasteurization can be a carrier of various diseases that can be transmitted from cows to humans. A heat sterilization process to inactivate is required.

Heat treatment methods for milk can be broadly divided into sterilization and sterilization. According to the International Dairy Federation (IDF), sterilization is heat treatment to minimize chemical, physical and sensory changes to the product. The purpose of this is to minimize possible health problems, and sterilization refers to a heat treatment method that aims to remove all microorganisms by applying heat treatment exceeding 100°C.

In addition, colostrum is reported to be rich in physiologically active ingredients such as immune components and growth factors as well as nutrients as a milk component produced only within 7 days after delivery. In the case of immunoglobulin, an important functional component of colostrum, a residual rate of about 73% was shown in the study result of heating at 71~74℃ for 40 seconds. It can be seen that sterilization conditions are very important for functional ingredients such as colostrum because they are destroyed.

On the other hand, since ultraviolet (Ultraviolet, UV) has different properties depending on the type of wavelength, it is being applied to a sterilization device by using the property according to the type of the wavelength of the UV.

Such a conventional sterilizer is fixed at a specific position and sterilizes by irradiating light to the surface or inside of the liquid. The part of the turbid liquid farthest from the UV lamp because it does not penetrate deep enough may reduce the effectiveness of sterilization.

1 is a perspective view of a colostrum sterilization apparatus equipped with a UV module according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line A-A' of FIG. 1, and FIG. 3 is an exploded perspective view of the impeller.

As shown, the colostrum sterilization apparatus equipped with the UV module of the present invention is connected to the power supply to perform agitation and sterilization operation in the colostrum storage bin, and the driving unit 30 and the rotating impeller 10 and the driving unit 30 ) by supplying the power supplied through the UV module to the shaft 20 to sterilize while rotating.

The driving unit 30 is inserted into the soccer shaft 320 and the soccer shaft 320 for driving the shaft 20 so that power is applied to drive the impeller and supply power to the rotating impeller, and rotates the power applied from the outside. It includes a slip ring 310 for supplying to the impeller.

The slip ring 310 may be configured as a general two-terminal slip ring for supplying power to a rotating object.

In other words, the present invention is configured to evenly sterilize colostrum while rotating the UV module while the impeller stirs the colostrum in the reservoir by installing the UV module 200 on the rotating impeller 10 .

To this end, the impeller 10 is provided with one or more rotating bodies (consisting of four rotating bodies in the drawing; 110, 120, 130, 140), and each rotating body is installed to be spaced apart from each other in the longitudinal direction in the longitudinal direction, but the light is directed toward the left and right walls Two first UV modules configured to be irradiated, respectively, and one second UV module installed to be irradiated with light in a downward direction in the longitudinal direction therein, wherein the second UV module is the two first UV modules to be installed between them.

Referring to the drawings, the first UV module 211 is installed so that the left side is irradiated with light, the other first UV module 212 is directed to the right side, and the second UV module 213 is installed to irradiate the bottom surface of the impeller. has been

Therefore, the impeller 10 is made of a material through which UV light is transmitted, and two first UV modules 211 and 212 and one second UV module 213 are mounted therein, and a depression 152 is formed along the edge thereof. The lower case 100 and the rotating shaft 20 of the agitator are coupled, and the power line is electrically connected to each UV module through the inside of the shaft 20 of the upper case 300 and the lower case 100 It may include a sealing ring 150 that is inserted into the recessed part 152 and is compressed when the lower case 100 and the upper case 300 are combined to form a sealing part.

In particular, the lower case 100 is made of any one of quartz, fused silica, or PMMA having a high monomer ratio, since light irradiated from the UV module installed therein must be transmitted.

Referring to FIG. 3 , a slip ring 310 is provided at an upper portion and an impeller 10 is provided at a lower portion based on the shaft 20 , and the impeller 10 receives power through the slip ring 310 and rotates while rotating. It operates to sterilize colostrum that is stirred through the UV module configured on each rotating shaft while stirring the colostrum.

That is, the rotating body of the present invention operates to sterilize colostrum that is stirred at the same time as the operation of stirring the colostrum while rotating.

Referring to the detailed configuration diagram of the lower case of FIG. 4, the lower case 100 is illustrated by taking four rotating bodies 110.120.130.140 as an example, and each of the UV modules is mounted on each rotating body 110, 120, 130, 140.

The first UV modules 211 and 212 are installed on the first rotating body 110 to face the left and right sidewalls of each rotating body, and one second UV module 213 is mounted on each of the mounting parts 111, 112 and 113 to face the lower side, respectively. do.

In addition, the first UV modules 221 and 222 are installed on the second rotating body 120 to face the left and right sidewalls of each rotating body, and one second UV module 223 is mounted on each mounting unit to face the lower side.

Similarly, in the third rotating body 130, the first UV modules 231,232 are installed to face the left and right sidewalls of each rotating body, and one second UV module 233 is mounted on each mounting unit to face downward.

And the first UV modules 241,242 are also installed on the fourth rotating body 140 to face the left and right sidewalls of each rotating body, and one second UV module 243 is mounted on each mounting unit to face downward.

Referring to the exploded perspective view of the impeller of FIG. 5 , three UV module mounting units are configured for each rotating body, and the UV modules are mounted to the left and right and to the lower side.

Specifically, the UV modules 211, 212, 213 are mounted on the mounting portions 111, 112, 113 of the first rotating body 110, respectively, and a recessed portion 152 is formed at the edge of each rotating body, and a sealing ring 150, which is a sealing member, is inserted and installed. After assembling so that the piece hole 160 of the lower case and the piece hole 360 of the upper case coincide with the upper and lower cases, the sealing ring 150 is compressed by the upper and lower cases when the upper and lower cases are combined with the piece 370 as a coupling member. to keep the case sealed.

Preferably, three pieces of the coupling member are inserted for each rotating body to firmly couple the rotating body, and the impeller is tightly coupled and sealed by the other four pieces in the center.

The first UV module and the second UV module may be composed of a plurality of LEDs.

Preferably, the first UV module irradiating the left and right sidewalls may constitute one module with four LEDs. In this case, since a total of 8 first UV modules are used in the present invention, a total of 32 LEDs may be required.

On the other hand, the second UV module may require a total of 20 LEDs by composing one module with 5 LEDs.

Referring to the drawings, the first UV module is configured only for each rotating body, whereas the second UV module has to advance to each rotating body and the central axis to irradiate light, so the second UV module is relatively the first UV module. Because the length is longer, the LED used is also used a lot.

These first and second UV modules may be composed of any one or more LEDs among LEDs of the same wavelength band or LEDs of different wavelength bands.

Since ultraviolet rays in the UV-A wavelength band (320 to 400 nm) have little sterilization power, sterilization is performed using the UV-C wavelength band (100 to 280 nm) or to be sterilized at 405 nm.

Generally known UV sterilization occurs at UV-C wavelengths (100-280 nm).

It is the principle of destroying DNA (the most effective at 270 nm among them), and sterilization at 405 nm is the principle of 'porphyrin reaction decomposition'.

In general, it is known that the UV of 253 nm is the wavelength with the best sterilization power. However, as a result of the actual experiment, it was confirmed that the wavelength with the highest sterilization power in sterilizing bacteria mixed in water was 270 nm.

Referring to the graph showing the relationship between the ultraviolet irradiation amount and the sterilization rate of FIG. 6 , it is a graph showing the relationship between the ultraviolet irradiation amount and the sterilization rate after mixing bacteria in water and irradiating ultraviolet rays for each wavelength. The initial concentration of bacteria mixed in water is 19~30×105 cfu/mL.

As a result of the experiment, when 270 nm ultraviolet rays were irradiated as much as 14 mJ/cm ² , it showed a sterilization rate of 99%, which is very superior to ultraviolet rays of other wavelengths.

Through these experiments, one is that the sterilization rate can be changed when the medium is air and water, and the other is that it is not a surface sterilization but sterilization of bacteria distributed in a three-dimensional space filled with a medium. Another is that, in the case of bacteria or viruses that are incorporated into water, normal DNA or RNA may be more sensitive to 270 nm.

As a result, as a result of the experiment, it was confirmed that the sterilization efficiency decreased as the wavelength increased in the + - direction with respect to 270 nm. It is intended to improve the sterilization efficiency by uniformly sterilizing colostrum that is stirred by the impeller using the moving colostrum.

In addition, sterilization at 405 nm requires a lot of energy compared to UV-C sterilization, and porphyrin reaction decomposition sterilization at 405 nm usually requires about 700 to 1,000 times more energy than sterilization based on the principle of DNA destruction.

It is also true that it takes a lot of time compared to UV-C sterilization.

On the other hand, even if the lowest power LED among UV-C wavelength LEDs is used, it is possible to sterilize more than 99.9% in less than 1 minute, but it is preferable to sterilize for 5 to 10 minutes.

In addition, it should be configured so that the sterilization time can be varied according to the amount of colostrum.

Preferably, when the amount of colostrum is determined, the sterilization time is automatically set.

On the other hand, since it is 'harmless to the human body' among the advantages of 405nm sterilization, it has the advantage of being relatively exposed to UV-C wavelengths harmful to the human body.

When irradiating such 405nm, there is an effect that can greatly extend the decay time of colostrum.

Therefore, the irradiation time of 405 nm should be longer than the irradiation time of the UV-C wavelength band.

Looking at the porphyrin absorbance curve of FIG. 7 , it can be seen that porphyrin absorbs the most at 405 nm.

In other words, the two first UV modules and one second UV module each or simultaneously emit light in the UV-C wavelength band (100 to 280 nm) for a first set time (5 minutes to 10 minutes), and the first set time By repeatedly irradiating light by a method of emitting light in a longer wavelength band (405 nm) longer than the first wavelength band, sterilization can be performed more efficiently.

Of course, the two first UV modules and one second UV module each have LEDs irradiated in the UV-C wavelength band and the 405 nm wavelength band, so that the wavelength band can be selected and irradiated as needed, but for example, the first UV The module may be irradiated in the UV-C wavelength band and the second UV module is irradiated in the 405 nm wavelength band.

Through this configuration, the colostrum sterilizing device equipped with the UV module of the present invention can be installed on a rotating impeller and sterilized by irradiating UV at various angles to the stirred colostrum, as well as selecting and irradiating UV in different wavelength bands. There is an effect that can sterilize colostrum more efficiently by making it possible.

Although the present invention has been described in detail with respect to the described embodiments, it is obvious to those skilled in the art that various changes and modifications are possible within the scope of the technical spirit of the present invention, and it is natural that such variations and modifications belong to the appended claims.
