Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to powdered, granular, chip-shaped and leaf-shaped foods (eg pepper, matcha, cereals, tea leaves, seaweed, seaweed, etc.) and irradiation objects such as medicines, cosmetics and hygiene products. The present invention relates to an electron beam irradiation processing apparatus and method for irradiating an electron beam to perform processing such as sterilization.

[0002]

BACKGROUND ART Generally, microorganisms are attached to foods regardless of their harmful effects, and the microorganisms propagate when various conditions such as temperature, humidity, PH and nutrients are established. Since the quality of foods is deteriorated along with the main proliferation and the diseases are caused by ingestion of the foods, various sterilization treatments have been performed for handling foods since ancient times. Since the sterilization treatment for killing all the bacteria is a part of the sterilization treatment for killing the bacteria, the sterilization treatment will be described here as a representative of this treatment.

Conventionally, a heating method, a chemical substance sterilization method and the like have been widely used as the present treatment method. The former method causes a great change in the food quality such as flavor and color, and the latter method is a regulation for preventing global warming in recent years. (Methyl bromide: Scheduled to be completely removed in 2005) and some substances have the problem that residual components are harmful to the human body. Therefore, as an alternative method, a method using heated steam or microwaves has been proposed and put to practical use, but it has a problem that it has a limitation on a processing speed and an object.

As a means for solving this method, an electron beam, X
Rays and γ rays may be used. However, this treatment causes irradiation damage to the object to be irradiated, and, for example, when the rice grains are irradiated with an electron beam, the taste is deteriorated due to the deterioration of starch and the like. Fungi generally predominantly adhere to the surface of the irradiated object in many food materials. Therefore, in order to perform the main sterilization treatment, it has been widely proposed to perform the irradiation treatment only on the surface of the irradiation target with a low energy electron beam having a relatively short range. ) Is irradiated with an electron beam while being conveyed by a vibrating conveyor (see JP 2000-304900 A, etc.), and is irradiated with an electron beam while being dropped into a thin film (JP-A-11-052100).
No.

When the surface of the object to be irradiated is subjected to electron beam irradiation for the purpose of sterilization or the like, it is necessary to invert or rotate the object to be irradiated at the electron beam irradiation section. However, in the case of using the vibration conveyor, the air flow transport device, etc., for example, when particles are overlapped with each other, the rotational force is not directly applied to all the particles, so that the surface of each irradiated object is There is a high possibility that the irradiation treatment cannot be effectively carried out, and thus the irradiation effects such as sterilization performance are non-uniform.
Further, since the electron beam irradiation unit is a passing process, it is necessary to perform the irradiation process again on the irradiated product in order to reprocess the unirradiated portion, and the irradiation efficiency becomes low.

The present invention has been proposed in view of the above-mentioned prior art, and is substantially uniform over a large number of objects to be irradiated, and on the surface of each object to be irradiated, without increasing equipment costs and processing man-hours and time. It is an object of the present invention to provide an electron beam irradiation processing apparatus and method capable of irradiating an electron beam on a substrate.

[0022]

Embodiments of the electron beam irradiation method and the irradiation system according to the present invention will be described below, but the present invention is not limited to these embodiments.

[First Embodiment] FIG. 1 is a side view of an electron beam irradiation unit of an electron beam irradiation system according to the first embodiment, and FIG. 2 is a schematic sectional view thereof.

As shown in these drawings, the electron beam irradiation processing apparatus 10 according to the present embodiment is an electron beam irradiation processing apparatus for irradiating an object 11 with an electron beam for processing.
A rotating drum 13 having a polygonal cross section, which is formed by inserting an object 11 to be irradiated therein and is rotatable by a rotation driving means 12.
And an electron beam irradiation means 16 for irradiating the inside of the rotary drum 13 with the electron beam 15 through the transmission window 14 provided in the rotary drum 13.

Here, the irradiation object 11 means, for example, powdery, granular, chip-shaped and leaf-shaped foods (eg pepper, matcha, cereals, tea leaves, wakame, seaweed, etc.), medicines, cosmetics and hygiene products. The term refers to those that are irradiated with an electron beam to be subjected to a treatment such as sterilization, but the present invention is not particularly limited as long as they are subjected to a treatment such as sterilization such as being irradiated with an electron beam.

The object to be irradiated 11 is separately placed in the rotary drum 13. The rotating drum 13 has a cross section of 6
It has a polygonal shape such as a prism or octagon. In the present embodiment, a hexagonal case is shown as an example.
By using a polygonal rotary drum, when the rotary drum is rotated, the irradiation object 11 inside is lifted to a certain height by the balance of the drag force from the wall surface, gravity, and the frictional force between the irradiation objects. After that, it can be made to fall freely, and as a result, the irradiation of the electron beam 15 irradiated inside becomes uniform.

The polygonal vertex of the rotary drum 13 is composed of a structure 13a corresponding to a beam.
An electron beam entrance window 14 made of a material and having a thickness capable of transmitting the electron beam 15 emitted from the electron beam irradiating means 16 and performing irradiation processing into the rotating drum 13 is densely attached to each surface between a. .

The electron beam irradiating means 16 irradiates the electron beam 15 from the electron beam generating source through the electron beam irradiating window 16a, and the electron beam transmitting window 14 provided inside the structure 13a of the rotary drum 13 serves to The irradiation object 11 is irradiated with the electron beam 15. Here, as the material of the electron beam irradiation window 14,
For example, a Ti thin film is used. In addition, the electron beam transmission window 14
Examples of the material include, but are not limited to, titanium (Ti), aluminum (Al), silicon (Si), and organic substances (such as polyimide).

It should be noted that the structure 13a does not have any significant unevenness in the drum. In addition, one end surface portion 17 of the rotary drum 13 in the axial direction is connected to a rotation drive means 12 that rotationally drives the rotary drum 13 via a chain belt 18.

Further, the one end surface portion 19 of the rotary drum 13 on the opposite side in the axial direction is densely attachable to and detachable from the rotary drum main body 13, and is of a hatch type or a rotary type, for example.
When the object 11 to be irradiated is carried in and out of the rotary drum 13, it is attached or detached or opened or closed.

An electron beam irradiation device 16 is installed above the rotary drum 13, and the electron beam irradiation device 16 is provided.
The electron beam 15 is irradiated toward the inside.

At this time, the rotary drum 13 is installed so that its central axis is in a direction orthogonal to the vertical direction.

Here, the acceleration energy of the electron beam 15 emitted from the electron beam irradiation device 16 is such that it can pass through the electron beam incident window 14 and mainly irradiate the surface layer of the object 11 to be irradiated. I shall.

The rotary drum 13 is internally provided with an object 11 to be irradiated.
In the state of holding, the rotation driving means 12 rotates in a certain direction at a constant speed. After performing the irradiation processing for a certain period of time, the one end face portion 19 is opened and the irradiation object 11 that has been irradiated with the electron beam is taken out, so that the irradiation object can be irradiated with the electron beam.

The number of corners of the sectional shape of the rotary drum 13,
Each element of each side length and each side angle may be appropriately set according to the property of the object to be irradiated and the installation amount in the single rotary drum 13.

For example, when the angle of repose of the irradiated object 11 is large, it is desirable that the angle is large.

Although not described in detail, in order to continuously irradiate the object 11 with the main electron beam, for example, the main body of the rotary drum 13 can be arbitrarily changed in posture position from one point on the central axis as a base point. It is possible to do. After the irradiation of the electron beam, the one end face portion 19 is opened and the posture is inclined so that the central axis direction has a component with respect to the direction of gravity, so that the one end face portion 19 is conveyed into the irradiated product collecting device (not shown). Things are effective for efficient processing.

Further, it is effective that the transportation environment is sterilized and is carried out in a fixed section area (not shown) equipped with a mechanism (not shown) capable of preventing the mixture of fungi from the outside.

Further, since the beams and the like generate heat particularly when the electron beam is irradiated, an air cooling device is installed at a position on the side surface of the rotary drum where it does not interfere with the electron beam irradiation device in order to eliminate the main heat generation. For this reason, it is effective to blow cooling air.

Here, an example in which the rotating means of the rotating drum 13 uses a chain belt as the rotation driving means is described, but the rotating means drives, for example, a gear directly connected to the rotating drum and the gear. For example, when the rotation control device for mechanically fits and transmits the rotational force, or when the drum mechanically contacts the pedestal rotated by the rotation control device and transmits the rotational force by frictional force, In particular, it is established without limiting the rotating means.

In the apparatus of this embodiment, the rotary drum 13
In the inside, when the rotary drum is stopped, the object to be irradiated is in balance with the drag force from the gravity / electron beam transmitting window and the beam structure and the force (frictional force) between the objects to be irradiated.

When the rotary drum 13 is rotated, the positions of the electron beam transmitting window 14 and the beam structure 13a in the space are sequentially changed with the rotation, and the position of the irradiation target 11 is set due to inertia. Since a shift occurs, as a result, the direction of the drag force acting on part of the irradiation target object 11 changes.

At this time, when the balance with the force between the objects to be irradiated is deviated, a part of the objects to be irradiated is displaced from the installation position while rotating in the rotary drum 13. Therefore, when the electron beam 15 is applied to the inside of the rotating drum 13 while the rotating drum 13 is being rotated, the entire surface of the object to be irradiated 11 inside the rotating drum 13 is effectively irradiated by the electron beam. Since it is directed to the irradiation side, it is possible to achieve uniform irradiation on the surface.

Since the centrifugal force acts on the object to be irradiated with the rotary motion of the rotary drum 13, the effect of the main centrifugal force is negligible as compared with the acting forces.
It is necessary to appropriately set the rotation speed of.

Since the object 11 to be irradiated also makes a slight moving motion in the axial direction during the rotational motion in the rotary drum 13, in order to ensure uniform irradiation of the object 11 to be irradiated, the above-mentioned electron It is desirable to simultaneously perform electron beam irradiation on the line incident window 14 in the axial direction. For this purpose, it is effective that the irradiation length of the electron beam 15 from the electron beam irradiation means 16 is as long as the axial length of the electron beam entrance window 14.

The rotary drum is provided with a transport system (not shown) so that the transport speed for the electron beam irradiation unit can be set independently of the rotation speed.

Then, as shown in FIG. 2, when the direction of conveyance is X, for example, during the conveyance, for example, in the electron beam irradiation area, low speed traveling or stopping for a certain period of time is performed to irradiate the rotating drum 13. It is possible to impart to the object to be irradiated 11 an effective rotational movement capable of uniformly performing the electron beam irradiation treatment on the surface of the object 11. As a result, the sterilization performance can be improved by a single irradiation process as compared with the conventional irradiation method that simply passes through the electron beam irradiation atmosphere. This can improve the system efficiency and reduce the irradiation damage of the irradiation object.

[Second Embodiment] FIG. 3 is a sectional view of a rotary drum portion according to a second embodiment.

Since the basic structure of this embodiment is the same as that of the first embodiment, the same reference numerals are given to the overlapping structures and the description thereof will be omitted.

In the present embodiment, the shape of the rotating drum is not limited to the polygon. At several points in the cross section, structures 3 corresponding to beams are provided on the respective surfaces of the structures 13a and 13a.
An electron beam entrance window 14 made of a material and a thickness through which an electron beam can pass is densely attached between a. A partition plate 21 is installed in the structure in the rotary drum.

The shape of the partition plate 21 (number of corners, length of each side, angle between each side) is the shape of the object 11 to be irradiated, and the single rotary drum 13.
It is necessary to appropriately set the installation amount inside, the cross-sectional shape of the rotating drum, and the incidence of the electron beam incident from the opposing electron beam transmission window on the irradiation object between the partition plates according to the shielding effect.

The end face structure of the rotary drum 13 and its peripheral components are the same as those in the first embodiment, and the irradiation object installed in the rotary drum is subjected to the electron beam irradiation treatment in the same manner as in the first embodiment. Can be done.

In the present invention, the shape of the partition plate is not limited to the shape from each beam portion toward the center of the rotating drum as shown in FIG. 3 (a), but as shown in FIG. It may be a shape or the like.

However, with the installation of the partition plate, as shown in FIG. 3B, a system that does not affect the irradiation process due to the shielding effect against the electron beam irradiation from the electron beam transmission window located above (see FIG. 3). It is necessary to construct (corresponding to D part).

In the present embodiment, the presence of the partition plate 21 produces a drag force direction component similar to that of the adjacent electron beam transmission window 14 in the first embodiment, so that the same effect as in the first embodiment is produced.

The object to be irradiated 11 between the adjacent partition plate 21 and the electron beam transmitting window 14 is supported by the partition plate which is relatively downward in the rotating process of the rotary drum, so that it is in that position. Since a part of the object to be irradiated is lifted to a higher level than in the case of the first embodiment and then dropped, the object to be irradiated can have a more rotational component. As a result, it is possible to improve the stirring efficiency of the irradiation target 11.

[Third Embodiment] FIG. 4 shows a sectional view of a rotary drum portion in a third embodiment.

Since the basic structure of this embodiment is the same as that of the first embodiment, the same reference numerals are given to the overlapping structures and the description thereof will be omitted.

In the present embodiment, a control device (not shown) is provided which can arbitrarily set the rotation direction of the rotary drum 13 to forward or reverse. In addition, the control by the control device can also set the rotation speed arbitrarily periodically or aperiodically.

Depending on the surface condition of the object to be irradiated and the installed capacity,
When objects to be irradiated are attached to each other, if they are rotated at a constant speed in the same direction, a part of each object to be irradiated remains in the same state on the bottom of the rotating drum, and only the upper part of the installed object to be irradiated. May make a rotational movement.

However, when the rotating speed and the rotating direction of the rotating drum are changed, the inertial force acting on the object to be irradiated along with the rotation and the frictional force on the surface in contact with the object below the inside of the rotating drum are changed. Makes a difference so that the attachment can be effectively separated.

This allows the present invention to be effectively established and the above-mentioned effects to be obtained even when the above-mentioned trouble occurs.

[Fourth Embodiment]

Since the basic structure of this embodiment is the same as that of the first embodiment, the same reference numerals are given to the overlapping structures and the description thereof will be omitted.

FIG. 5 shows a side view of the rotary drum portion in the fourth embodiment.

In the present embodiment, the rotating drum main body 13 is provided with the swinging means 31 provided with the θ movement mechanism for performing the cradle movement so that the main body central axis draws a straight line or a curved line. Then, the swinging means 31
This makes it possible to perform a cradle exercise as needed during electron beam irradiation and non-irradiation.

The cradle movement is not limited to a fixed angle and a fixed speed. Therefore, for example, at the time of supplying the raw material before the electron beam irradiation, the deflection angle θ becomes large and one end is disengaged, so that the rotary drum opening is opened upward, so that this measure can be easily performed.

Further, by performing the reverse process after irradiation, it becomes possible to take out the irradiated object to be irradiated from the rotary drum.

In the case where the objects 11 to be irradiated are adhered to each other and the objects to be irradiated interfere with each other at the joint between the beam and the electron beam transmitting window 14 shown in the present embodiment, only the rotational movement with respect to the axis center causes a problem. The situation cannot be avoided. However, it is possible to generate a force in a direction different from that during the rotational movement to the irradiated object by giving a positive means for the axial movement of the irradiated object in the rotating drum by the cradle movement, The trouble can be avoided.

When the object to be irradiated is supplied into the rotary drum from the end of the rotary drum, the object to be irradiated is not evenly arranged in the axial direction of the rotary drum. When the irradiation process is performed in this state, the rotational force applied to the irradiation object becomes non-uniform due to the main axial distribution. However, since the object to be irradiated can be transferred in the axial direction of the rotary drum by applying the main cradle movement to the rotary drum, it is possible to deal with the main problem.

[Fifth Embodiment]

Since the basic structure of this embodiment is the same as that of the first embodiment, the same reference numerals are given to the overlapping structures and the description thereof will be omitted.

FIG. 5 shows a side view of the rotary drum portion in the fifth embodiment.

In this embodiment, the rotary terminals 41 are attached to both end surfaces of the rotary drum 13, and the main rotation introducing terminal 4 is provided.
1 into the rotary drum 13 through the inert gas 42 (nitrogen,
An electron beam irradiation process is performed while introducing a rare gas.

Radiation damage during electron beam irradiation may be greatly affected by oxidation by oxygen. When electron beam irradiation is performed in an inert gas atmosphere as in the present embodiment, it is possible to perform irradiation processing with relatively less irradiation damage while avoiding the problem.

Therefore, for example, when the irradiation treatment for food is performed, the flavor deterioration can be suppressed.

[0077]

As described above, according to the present invention, there is provided an electron beam irradiation processing apparatus for irradiating an object to be irradiated with an electron beam and processing the object. A rotary drum having a polygonal cross section which is rotatable by a rotary driving means, and an electron beam irradiating means for irradiating an electron beam from the outside of the rotary drum to the inside of the rotary drum through a transmission window provided in the rotary drum, By irradiating the inside of the rotating drum with an electron beam while rotating the rotating drum, the entire surface of the object to be irradiated can be effectively irradiated by the electron beam irradiation side according to the number of rotations. It is possible to irradiate the surface with an electron beam uniformly.

Further, since the partition plate is provided in the rotary drum, a part of the object to be irradiated is lifted up and then dropped downward. Can have.

Further, since the control means for changing the rotating direction and the rotating speed of the rotating drum is provided, the inertial force acting on the object to be irradiated in accordance with the rotation and the contact with the object to be irradiated below the inside of the rotating drum. By causing a difference in the frictional force on the running surface, it is possible to effectively dissociate the adherence of the irradiated object.

Further, since the rotating drum is provided with the swinging means, it is possible to move the irradiated objects in the axial direction of the rotating drum due to the cradle movement, thereby adhering the irradiated objects to each other and joining the beam and the electron beam transmitting window. Even when interference occurs on the irradiated object in the area or the like, the electron beam can be efficiently irradiated.

Further, since a means for introducing an inert gas to make the inside of the rotary drum an inert gas atmosphere is provided,
Oxidation due to oxygen can be suppressed for irradiation damage during electron beam irradiation.
