As stated in the bulletin,
There has been one that evenly sterilizes the granules by irradiating the granules with ultraviolet rays while stirring.

った。However, since sterilization with chemicals such as ethylene oxide and ozone has persistence, secondary treatment may be necessary. Particularly, for example, powdered Chinese herbs and spices, etc. With respect to the food powders and the like, there was a great adverse effect on the persistence. Moreover, there was a risk of generating resistant bacteria. In addition, heat sterilization using steam heat raises energy costs, and further, particularly for foods, there are drawbacks such as discoloration, deterioration, and fragrance flying, and there is a drawback that it is not suitable for heat-resistant bacteria.

There is a drawback that it does not exist. Further, the method of uniformly sterilizing the powder and granules by stirring has a drawback that the irradiation efficiency is poor because only the powder and granules on the surface layer can be irradiated with ultraviolet light at each moment.

分離する分離手段とを備えたことを特徴とする。The apparatus for sterilizing powder and granules according to the present invention comprises an air flow generating means for generating an air flow in a pipe passage and a powder and granules in the air flow to generate a solid-gas two-phase flow. Granules supply means, a sterilization cylinder connected to the pipe path so that the solid-gas two-phase flow is supplied, an ultraviolet sterilization lamp installed in the sterilization cylinder, and discharged from the sterilization cylinder It is characterized by comprising a separating means for separating the sterilized solid-gas two-phase flow into a powder and a granular material and an air stream.

ことになる。As a result, the powder or granules are carried by the air flow into the sterilization cylinder, and the powder or granules are diffused by the air flow in the sterilization cylinder. That is, due to the air flow, each particle moves in the sterilization cylinder while rotating or moving toward or away from the UV germicidal lamp, and each grain is evenly UV-sterilized. UV rays can be received from the lamp, and the sterilization efficiency will be greatly improved.

なる。The air flow generating means may be capable of adjusting the flow velocity of the air flow. This makes it possible to adjust the time for the powder or granules to pass through the sterilization cylinder and to adjust the sterilization time (the time during which it receives ultraviolet rays).

保することができる。A plurality of sterilization cylinders provided with the ultraviolet sterilization lamp may be provided. According to this, it is possible to secure a long path for sterilization while making each of the sterilization cylinder and the ultraviolet sterilization lamp small. Further, as described above, when the time for the powder or granules to pass through the sterilization cylinder is increased by adjusting the flow velocity of the airflow, the sterilization amount of the powder or granules per unit time is reduced, but the sterilization is performed. By installing a plurality of cylinders and lengthening the sterilization path length, it is possible to secure a necessary sterilization time without reducing the amount of sterilization treatment of powdery particles per unit time.

間を長くとることが可能となる。The inlet side of the sterilization cylinder to which the solid-gas two-phase flow is supplied may be located below the outlet side from which the solid-gas two-phase flow is discharged. Here, the flow velocity of the granules conveyed horizontally is only slightly slower than the flow velocity of the air flow, but by positioning the inlet side of the sterilization cylinder below the outlet side, the flow velocity of the granules can be reduced. Since it becomes a value obtained by subtracting the sedimentation speed of the powder or granules from the flow speed of the airflow, it becomes possible to set the flow speed of the powder or granules to a speed significantly slower than the flow speed of the airflow, and to extend the sterilization time.

ため、残留といった不具合が解消されることになる。Since the sterilization cylinder is erected substantially vertically and the outlet side is positioned right above the inlet side, it is possible to prevent powdery particles from remaining in the sterilization cylinder. In other words, in the sterilization cylinder, the powder particles settle in the direction of gravity, but because the sterilization cylinder is set up almost vertically and an air flow is generated just above, which is the opposite of the direction of gravity, it settles. However, the operation of getting on the air flow again is repeatedly performed, and it is prevented that the particles settle down and are not left on the inner wall of the sterilization chamber as they are, so that the problem such as remaining is eliminated.

の発見が容易となる。The airflow generating means may generate a pressure higher than atmospheric pressure at an upstream point of the pipe path to generate an airflow. As a result, since the pressure inside the piping path is always positive, even if there is a leak in the piping path of the powder sterilizer, this leak occurs in the direction from the inside of the tube to the atmosphere, so that various bacteria enter into the piping path. Mixing can be prevented and the discovery becomes easy.

れることになる。The inner wall of the sterilization cylinder may be an aluminum wall. Since the ultraviolet rays emitted from the ultraviolet germicidal lamp are highly efficiently reflected by the aluminum wall, the particles passing through the germicidal cylinder are direct ultraviolet rays from the ultraviolet germicidal lamp and ultraviolet rays reflected by the aluminum wall. Therefore, sterilization will be performed with high efficiency.

This makes it easy to replace the sterilization cylinders and ultraviolet sterilization lamps, and as mentioned above, when multiple sterilization cylinders are provided, it is easy to add or remove sterilization cylinders, and the types of powder and granules and types of bacteria It is also possible to freely adjust the sterilization path length according to the above.

ら、このような温度に設定することも可能である。It comprises a temperature sensor installed in the sterilization cylinder, a heater installed upstream of the powder and granular material supply means, and a control unit for controlling the heater based on the measurement value of the temperature sensor. A pipe temperature control device may be provided. This makes it possible to maintain the temperature inside the sterilization cylinder at a temperature at which the amount of light emitted by the ultraviolet sterilization lamp becomes maximum. Alternatively, irradiation of ultraviolet rays at a temperature at which the bacterium is activated causes the bacterium to easily die, and thus such a temperature can be set.

することになる。According to the above-mentioned structure, the powder particles supplied from the ejector 8 are transferred by the compressor 1 to the piping path 1
4 is carried on the airflow generated in the sterilization cylinder 9 and is carried into the sterilization cylinder 9. In the sterilization cylinder 9, the powdery particles are diffused by the airflow. That is, due to the air flow, the particles move in the sterilization cylinder 9 while rotating one by one or approaching or moving away from the ultraviolet sterilization lamp 19, and each particle is evenly distributed. The ultraviolet rays from the ultraviolet germicidal lamp 19 can be received, and the germicidal efficiency is significantly improved.

気流の流速を調整できる。このように気流の流速を調節
できることにより、粉粒物が殺菌シリンダー９中を通過
する時間を調節して殺菌時間（紫外線を受けている時
間）を調整することが可能となる。In the compressor 1, the discharge pressure of the compressed air can be adjusted, and the flow velocity of the air flow can be adjusted by adjusting the discharge pressure. Since the flow velocity of the airflow can be adjusted in this way, it becomes possible to adjust the time for the powder or granules to pass through the sterilization cylinder 9 to adjust the sterilization time (the time during which it receives ultraviolet rays).

することができる。Since a plurality of sterilizing cylinders 9 equipped with the ultraviolet sterilizing lamp 19 are provided, the sterilizing cylinders 9 are provided.
Also, it is possible to secure a long path for sterilization while making each of the ultraviolet germicidal lamps 19 small. Furthermore, as described above, when the time for the powder or granules to pass through the sterilization cylinder 9 is increased by adjusting the flow velocity of the air flow, the powder or granule sterilization processing amount per unit time is reduced, By installing a plurality of sterilization cylinders 9 and lengthening the sterilization path length, the required sterilization time can be ensured without reducing the amount of sterilization treatment of powdery particles per unit time.
【００３２】前記殺菌シリンダー９の入口側を出口側よ

し、殺菌時間を長くとることが可能となる。Since the inlet side of the sterilization cylinder 9 is located below the outlet side, the following advantages can be obtained. That is, the flow velocity when the granular material is transported horizontally is
Although it is slightly slower than the flow velocity of the air flow, the flow velocity of the powder flow is controlled by positioning the inlet side of the sterilization cylinder 9 below the outlet side and carrying the powder and grain against gravity. It becomes a value obtained by subtracting the sedimentation velocity of the powder or granules from the flow velocity, and it becomes possible to set the flow velocity of the powder or granules to a velocity that is significantly slower than the flow velocity of the air stream, and to extend the sterilization time.

るため、残留といった不具合が解消されることになる。In particular, in this embodiment, the sterilizing cylinder 9 is erected in the vertical direction to supply the solid-gas two-phase flow from the lower part,
Since the powder is discharged from the upper part, it is possible to prevent the powdery material from remaining in the sterilization cylinder 9. That is, in the sterilization cylinder 9, the powdery particles settle in the direction of gravity, but because the sterilization cylinder 9 is set up in the vertical direction and an upward airflow opposite to the direction of gravity is generated, settling occurs. Even then, the operation of getting on the airflow again is repeatedly performed, and it is prevented that the particles settle down and remain on the inner wall of the sterilization chamber 20 as they are.

経路内への混入を防止でき、又その発見が容易となる。The compressor 1 has the piping path 1
Since a pressure higher than the atmospheric pressure is generated at the upstream point of 4 to generate the air flow, the inside of the piping path 14 is always a positive pressure. As a result, even if a leak occurs in the pipe path 14, this leak occurs in the direction from the inside of the pipe to the atmosphere, so that it is possible to prevent contaminants from entering the pipe path, and it is easy to find the leak.

率で殺菌が行われることになる。Since the inner wall of the sterilization cylinder 9, that is, the inner wall surface of the sterilization chamber 20 is formed by aluminum polishing or aluminum vapor deposition, the ultraviolet rays emitted from the ultraviolet sterilization lamp 19 are radiated by the inner wall surface of the sterilization chamber 20. It is reflected with high efficiency. As a result, the powder or granules passing through the sterilization chamber 20 receive both the direct ultraviolet rays from the ultraviolet sterilization lamp 19 and the ultraviolet rays reflected by the inner wall surface of the sterilization chamber 20, and sterilization is performed with high efficiency. Will be seen.

じて殺菌経路長を自在に調節することも可能になる。The sterilizing cylinder 9 has a flange 17 at its upper and lower ends for connecting to the pipe passage 14.
Since it is easy to replace the sterilization cylinder 9 and the ultraviolet sterilization lamp 19, as described above, when a plurality of sterilization cylinders 9 are provided, it is easy to add or remove the sterilization cylinders 9 It is also possible to freely adjust the sterilization path length according to the type of bacterium and the type of bacterium.

とによって、より効果的な殺菌が行える。A temperature sensor 13 installed in the sterilization cylinder 9, a heater 5 installed upstream of the compressor 1, and a control means 12 for controlling the heater 5 based on the measured value of the temperature sensor 13. Since it is provided with the in-tube temperature control device, the temperature inside the sterilization cylinder 9 can be maintained at the temperature at which the ultraviolet sterilization lamp 19 emits the maximum amount of light. Also, irradiation with ultraviolet rays at a temperature at which the bacteria are activated (for example: 35 ° C to 40 ° C) causes the bacteria to easily die. By setting this temperature, more effective sterilization can be performed.
【００３８】尚、この実施の形態では、気流発生手段と

い。In this embodiment, the compressor 1 is used as the air flow generating means, but a blower may be used, or in the case where the piping path 14 is strictly sealed, the blower is installed at a downstream point of the piping path 14. It may be arranged to generate a pressure lower than atmospheric pressure to generate an air flow.
【００３９】又、殺菌シリンダー９の入口側を出口側よ

できるという効果は得ることができる。Further, when the inlet side of the sterilization cylinder 9 is located above the outlet side, it becomes difficult to adjust the flow rate of the powder or granules, but the sterilization efficiency can be improved by the diffusion of the powder or granules. The effect can be obtained.

いものである。It is also conceivable to mix ethylene oxide or the like in the air stream and use sterilization with a chemical such as ethylene oxide and sterilization with ultraviolet light together.
It can be expected that a large sterilization effect can be obtained by the combined use of the chemicals and ultraviolet rays while minimizing the adverse effect of the chemicals used by reducing the amount of the chemicals used as much as possible. Furthermore, by using a closed circuit in which the piping path 14 is isolated from the outside and using, for example, an inert gas as the air flow, it becomes possible to sterilize the powder or granules that are vulnerable to oxidation. Further, although the flange is used as the joint means, a coupling means may be used instead of the flange.
