DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter mounting structure for a lid of a mushroom cultivation container.

[0002]

2. Description of the Related Art Conventionally, when cultivating edible mushrooms in a container, fresh air is supplied from the outside of the container to the inside, and in order to prevent microorganisms outside the container from entering the container, The mushroom cultivation container is provided with a filter-provided air passage hole (hereinafter, referred to as "aeration filter").

[0003] In this mushroom cultivation container, the ventilation filter is mostly provided on the lid as a result of taking into account the handling and the like.

[0004] In a lid with a ventilation filter used for container cultivation, if the position where the filter is attached is on the upper surface of the lid, the containers cannot be stacked, and the container is turned upside down to remove the culture medium. When a method of cultivating mushrooms that uniformly decomposes is performed, a large amount of metabolic water from the culture medium cannot be accommodated when the lid accumulates.
In 188551, there is proposed a lid of a mushroom cultivation container provided with a ventilation filter on a side surface of the lid and at a position separated from the bottom surface.

[0005] In the lid of the cultivation container, since the position where the filter is installed is on the side of the lid, when the container is inverted, a large amount of metabolic water comes out of the culture medium and accumulates in the lid. However, the filter part does not soak in the metabolic water.

[0006]

SUMMARY OF THE INVENTION However, Japanese Patent Application No. Hei 6-1
In the cover of the mushroom cultivation container proposed in No. 88551, since the filter is fixed to the cover, when the filter is damaged or contaminated for some reason, it is necessary to replace the entire cover. Also, when adjusting the coarseness of the filter, the entire lid must be replaced, which is inconvenient in terms of handling and cost.

[0007] In addition, there has been an idea of replacing the filter with the lid, but a gap is easily formed when the filter is attached to the lid, and germs may enter the container or the mounting itself may be troublesome. There was a problem of slipping.

Therefore, the present invention has been made in view of the above problems, and has found that a filter provided on a lid of a mushroom cultivation container may be damaged,
When it becomes contaminated, the filter can be easily replaced without replacing the entire lid, and even if the filter is replaced, there is no gap between the mushroom and the mushroom cultivation container. The object of the present invention is to provide a structure for mounting a filter on a lid.

[0009]

Means for Solving the Problems In order to achieve the above-mentioned object, a filter mounting structure for a cover of a mushroom cultivation container according to the present invention comprises a filter in which a filter is provided on the cover of a mushroom cultivation container. In the mounting structure of the filter of the disposing portion, a fitting recess is formed in the cover of the mushroom cultivation container, the fitting recess having an opening on the outer surface of the side wall of the cover, and a cover is provided on the bottom wall of the fitting recess. An air passage hole penetrating from the inner surface side to the outer surface side of the side wall is provided, and a filter is inserted into the fitting concave portion so that the air passage hole is entirely covered with the filter, and the filter is inserted. A filter holding plate having an air passage hole is removably attached to the opening of the fitting recess.

[0010] In the above configuration, the position of the filter disposing portion where the filter is disposed on the lid is
Although not particularly limited, when the mushroom cultivation container is inverted,
Even if metabolic water discharged from the culture medium accumulates on the bottom wall of the lid,
It is preferable that the filter is disposed at a position where the filter is not contaminated with the metabolic water, because the filter for air circulation is not blocked by the metabolic water.

It is difficult to specifically limit the position of the filter mounting portion on the lid as described above, depending on the size or type of the container or the culture medium. For example, a circular lid having a diameter of 18 cm is difficult. When the culture medium of about 3000 cm ³ is inverted and placed, the distance that the filter separates from the bottom wall of the lid is almost no problem if it is 1 cm or more.
There is no problem if it is 2 cm or more.

[0012] Further, the filter disposing portion may be provided on the lid body, and may be provided on the entire side wall of the lid body. On the other hand, the type of filter is not particularly limited, and for example, a filter made of nonwoven fabric is most commonly used. The shape of the fitting recess may be circular or square, and is not particularly limited.

The shape and size of the air vent are not particularly limited as long as air can pass between the outside of the lid and the inside of the lid.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a filter mounting structure in a lid of a mushroom cultivation container according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a side cross-sectional view showing a state in which a lid having an embodiment of a filter mounting structure in a lid of a mushroom cultivation container according to the present invention is attached to a mushroom cultivation container.

FIG. 2 is an exploded perspective view of a filter mounting portion of the lid. FIG. 3 is a side sectional view of a mounting portion of the filter shown in FIG.

As shown in FIG. 1, the mushroom cultivation container 1 comprises:
This is a container with a lid, which is a storage unit 3 for storing a culture medium A, which has a bottomed cylindrical body having an inverted frustum-shaped side surface having a lower diameter smaller than the upper diameter, and the lid 2 is attached. . Lid 2
Is on the side wall 26 as shown in FIGS.
In addition, a plurality of filter disposing portions 21 are disposed at three positions separated from the bottom wall 24, and a support for supporting the culture medium when the container is turned upside down is provided inside the lid 2. Three or more members 22 are provided. At the center of the bottom wall 24 of the lid 2, a seed inoculation hole 23 for inoculating a seed is provided.

As shown in FIGS. 2 and 3, the filter disposing portion 21 includes a fitting recess 4 formed by opening the outer surface of the side wall of the lid 2, a filter 5, and a filter holding plate (hereinafter, referred to as a filter holding plate). Only described as "pressing plate.") 6. The fitting recess 4 is provided with an air passage hole 40 penetrating from the inner surface 27 to the outer surface 28 of the lid side wall 26 in the bottom wall 41, and an air passage hole 60 in the holding plate 6. Have been.

The opening 42 of the fitting recess 4 is
A groove 43 into which the pressing plate 6 is fitted and a retaining claw 44 are provided so that the holding plate 6 can be detachably attached.

As shown in FIGS. 1 to 3, the filter arrangement section 21 having the above-described structure
Are provided by being sandwiched between the bottom wall 41 of the fitting recess 4 and the holding plate 6. Further, when the lid 2 is attached to the mushroom cultivation container 1, air moves only inside and outside the container only in the filter disposing portion 21, and in other portions, air can move freely. It is in a sealed state so as not to be.

On the other hand, in the filter disposing section 21,
The filter 5 has an air passage hole 40 provided in the fitting recess 4 and an air passage hole 6 provided in the holding plate 6.
Since all zeros are closed, even if air is passed through, it prevents germs and the like from entering the mushroom cultivation container 1 and maintains the humidity in the mushroom cultivation container 1.

Next, a method of cultivating mushrooms using the lid will be described. First, an inoculum inoculation hole 23 provided at the center of the bottom wall 24 of the lid 2 of the mushroom cultivation container (hereinafter, referred to simply as “container”) 1 is opened under a sterile room, and the inoculum is inoculated. The seed medium is inoculated from the hole 23 into the culture medium A filled in the storage part 3 of the container 1. Next, a large number of the containers 1 sealed with the cover 2 covered with the inoculum inoculation hole 23 are arranged on a shelf or the like in a culture room at an appropriate temperature and humidity, and the inoculum inoculated to the culture medium A is cultured. At this time,
The containers 1 may be stacked vertically.

About 30 days after the cultivation, the mycelium spreads over the entire surface of the culture medium A at a sufficient density. After a while
The container 1 is turned upside down as shown in FIG. Then, as shown so far in FIG.
And the portion of the culture medium A that was in close contact with the bottom surface 31 was separated from the bottom surface 31 of the storage section 3 and dropped, as shown in FIG.
The support member 22 formed on the inner surface of the lid 2 and at a position separated from the bottom surface supports the cover 2 at a height separated from the bottom surface.

At this time, since the culture medium A moves from the small-diameter part of the storage part 3 to the large-diameter part, the side surface A1 and the bottom surface A2 of the culture medium A are separated from the side surface 30 and the bottom surface 31 of the storage part 3 33 are formed. Then, the air supplied from the filter 5 also flows through the gap 33 to the side surface A1 and the bottom surface A2 of the culture medium A, and the decomposition of the culture medium A proceeds.

At this time, the metabolic water generated by the elongation of the hyphae accumulates in the metabolic water storage space 25.
Is not immersed in metabolic water and fresh air is maintained.

In this way, the decomposition of the culture medium A proceeds uniformly, and after about 50 days of culture after the reversal, the culture medium A becomes mature. When the culture medium A has matured, it is removed from the container 1 and placed in an environment suitable for development to generate fruiting bodies, which are grown. As described above, the cultivated culture medium A has a sufficient density of mycelia, so that the entire culture medium A has sufficient strength and can be prevented from being damaged by handling.

In addition, since the density of mycelia and the decomposition of the culture medium are uniform, the ripening period can be shortened, and the moisture on the surface of the culture medium is reduced. The performance is improved. In addition, the fruiting body is generated smoothly, the generation density is high, and an effect that efficient cultivation can be obtained is obtained.

The cover 2 is formed in substantially the same cross-sectional shape as the storage section 3 (circular in the case of FIG. 1), and the position of the filter 5 and the support member 22 is at a height separated from the bottom surface. In addition, the metabolic water storage space 25 formed below the culture medium A has a sufficient capacity, so that even when the amount of metabolic water is large, wetting of the filter 5 and wetting of the culture medium A are prevented.

Further, since the lid 2 has no complicated structure such as an air flow path, it is easy to perform cleaning and sterilization. But it can be used. Further, by repeatedly using the filter 5 of the lid 2,
When clogging, contamination, or breakage occurs due to scum or the like of the culture medium A, the holding plate 6 fitted in the fitting recess 4 is formed in the filter disposing portion 21 of the lid 2 by the groove. After removing the filter 5 from the holder 43 and replacing the filter 5 held down by the holding plate 6 with a new one, the holding plate 6 is fitted into the groove 43 again. The filter 5 can be newly disposed by operation.

Further, when the filter 5 is provided by the above method, the filter 5 is not twisted or wrinkled, and the air passage hole 40 formed in the fitting recess 4 and the holding member can be easily operated. Since the air passage hole 60 provided in the plate 6 can be completely closed, there is no need to worry about bacteria entering the container.

In the above process, until the mycelium spreads on the culture medium A, the culture medium A is easily contaminated by external germs, and the culture medium A tends to dry out. However, the filter 5 provided on the lid 2
Since air and carbon dioxide gas pass through, but does not allow the passage of contaminants such as germs and moisture, they also have a role of preventing invasion of germs and the like into the container 1 and enhancing moisture retention in the container 1. .

Further, by inverting the container 1, the metabolic water generated in the culture medium A is discharged from the culture medium A and accumulates in the metabolic water storage space 25, so that the main body of the culture medium A is appropriately dried and spread. An environment suitable for the formation of fruit body primordium from the mature portion of the hyphae is provided. Further, the structure of the filter disposing portion 21 provided on the lid 2 allows the filter 5 to be easily attached and detached by an easy operation. Therefore, it is necessary to replace the filter 5 due to contamination, clogging or breakage of the filter. When pressed, it is possible to replace only the filter 5 with a new one without replacing the entire lid 2.

Moreover, the groove 43 and the pawl 44 provide
Since the holding plate 6 is securely locked, the filter 5 is also securely disposed, so that a gap is formed between the filter 5 and the air passage hole 40 and / or the air passage hole 60, and various bacteria are removed from the container. 1 has a structure that does not easily enter the inside.

[0033]

As described above, the filter mounting structure of the lid of the mushroom cultivation container according to the present invention can be used to damage the filter provided on the lid of the mushroom cultivation container,
When it becomes contaminated, it is easy to replace only the filter with a new one without having to replace the entire lid, and moreover, the filter is as firm as when the filter and the lid are integrally formed. Since it is attached, there is no concern that the culture medium in the mushroom cultivation container is contaminated, and the cost of the mushroom cultivation container can be kept low.
