Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an improvement of a frame on which a perforated disk of a disk type solid culture device such as a disk-forming koji making device or a koji stocker is placed.

[Conventional technology]

A plan view of FIG. 4 shows a fan-shaped unit frame forming a perforated disk frame of a conventional disk-shaped solid culture device. This is a fan shape in which the entire circumference of a disc is divided into a plurality of parts, and a plurality of these parts are arranged to form a circular frame, and a perforated disc is placed on the resulting frame to form a perforated disc floor. The fan-shaped unit frame has middle crosspieces 12 in both vertical and horizontal directions that intersect in a grid pattern, and the size of the square is approximately 200 mm x 200 mm. In this way, the conventional perforated disk frame was divided into fine sections in a grid pattern.

[Problem to be solved by the invention] Because the perforated disc frame has a grid-like grid, there is a problem in that it is difficult to clean the area under the perforated disc, and in particular, it is necessary to check the cleaning after each square. The cleaning workability of automatic cleaning has been problematic, as it has been necessary to change the direction of application of the cleaning nozzle in various ways. Also, although the frames 10, 10 on both sides of the fan-shaped unit frame extend radially, the vertical bars 11, 11 closest to these frames 10, 10 do not extend radially. Near vertical bars 11, 11
They are lined up at an angle, and the thin square section C where they are close to each other is particularly difficult to clean. Furthermore, there are many welding points in manufacturing, which increases the number of man-hours and increases the cost.

[Means to solve the problem]

Therefore, in the present invention, in order to solve the problems of the prior art described above, a perforated disc frame is formed in a circular shape within a circumferential frame 13 by a plurality of fan-shaped unit frames 1, and on which a perforated disc 3 is placed. The disk-shaped solid body is characterized in that the fan-shaped unit frame 1 is reinforced with radial middle crosspieces 2 that are stretched mainly in the radial direction at intervals in the frames 10, 10 that extend radially on both sides. They developed a perforated disk frame for a culture device. In the present invention, "with radial middle bars 2 stretched radially at intervals" refers to a case where only a large number of radial middle bars 2 are arranged radially from the radial center to the outer periphery. However, from the viewpoint of strength, it also includes a good example in which several horizontal middle bars, that is, several horizontal bars 4 are provided at appropriate intervals, as will be explained in the examples below. are doing. In other words, instead of providing middle bars at almost the same pitch vertically and horizontally to form a lattice-like grid as in the past, the middle bars in the horizontal direction are kept to the minimum necessary and are provided at large intervals.

[Effect]

As mentioned above, since the perforated disk frame of the disk-type solid culture device of the present invention is mainly composed of the radial middle crosspieces 2 in the radial direction, the cleaning device reciprocates only in the radial direction of the perforated disk 3. It is only necessary to install a nozzle or a pipe having a large number of upward nozzles fixed in the radial direction, and there is no need to vary the application direction of the cleaning nozzle as in conventional products.
In addition, the plurality of vertical bars in the middle bar of the conventional product were arranged in parallel in the vertical direction, but the radial middle bar 2 of the product of the present invention extends radially.
The frames 10, 10 on both sides and the radial middle beams 2, 2 closest to these do not approach each other to the extent that they intersect, and there is no possibility of forming a narrow square portion C as in the above-mentioned conventional product. Furthermore, unlike conventional products, the center beams are not finely divided into grids, so there are fewer welding locations, which helps reduce manufacturing man-hours.

【Example】

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a partially cutaway plan view of a perforated disc portion of a disc koji making apparatus using a perforated disc frame of the present invention. FIG. 2 is an enlarged plan view of the fan-shaped unit frame. FIG. 3 is a side view of the same. As is clear from FIG. 1, the perforated disk frame of the disk-type solid culture device of the present invention is composed of an aggregate of fan-shaped unit frames 1 each having a shape in which the entire circumference of a perforated disk 3 is divided into a plurality of parts. The perforated disks 3 are arranged in a circle so that they can be placed inside the circumferential frame 13.
Here, the main feature of the present invention is that, as shown in FIG. 2, the unit frame 1 is mainly reinforced with radial middle beams 2 stretched in the radial direction. As is clear from the figure, the radial middle crosspiece 2 extends radially, and the frames 10 on both sides,
10 also extends radially. Also,
Five (not limited to) horizontal bars 4 are stretched between the inner circumferential part and the outer circumferential part of the radial middle bar 2 to reinforce the radial middle bar 2 and the porous disk frame itself. The sections divided by the horizontal bars 4 and the middle bars 2 between the sections are not continuous radially in a straight line, but are maintained radially in each section, but the outermost section The number of middle bars 2 in the inner circumference section is not all extended to the inner circumferential section, but the number of middle bars 2 in the inner circumferential section is extended so that the distance between adjacent middle bars 2 in the inner circumferential section is maintained at a predetermined distance or more. The number of books has been thinned out. The number of horizontal bars 4 is approximately 1/5 compared to that of conventional products.
Therefore, the manufacturing man-hours are reduced accordingly.

[Effect of the idea]

As described in detail above, the perforated disk frame of the disk-shaped solid culture device of the present invention has a non-lattice-like central crosspiece, so the frame can be completely cleaned only by the water jetted from the nozzle on the cleaning pipe to the bottom surface of the perforated disk. This enables resource-saving and labor-saving effects by simplifying the cleaning equipment and shortening the cleaning time. In addition, by reducing the man-hours required to manufacture the perforated disk frame and reducing costs, solid-state culture devices such as disk koji making equipment and koji stockers can now be provided at low cost. .
