Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mushroom cultivation container suitable for use in the cultivation of mushrooms such as shiitake mushrooms.

[Conventional technology]

Generally, when cultivating shiitake mushrooms, a cultivation container is filled with a culture medium, an inoculum is inoculated by making an inoculation hole from above the culture medium, and the mycelium is spread in a culture room, after which the medium is removed from the cultivation container. Then, the removed culture medium is transferred to a cultivation container, and cultivation is performed in a growth room.

By the way, in Shiitake mushroom cultivation, cultivation containers are used in the mycelium cultivation process, but conventional cultivation containers are formed into a cylindrical shape with a bottom, and an opening is provided at the top end from which the medium stored inside can be taken out. Ta.

[Problem to be solved by the invention]

However, since the bottom of conventional cultivation containers is completely sealed, the following problems have occurred.

First, the carbon dioxide generated from the hyphae on the bottom side of the cultivation container is difficult to be discharged to the outside, and the oxygen from the outside is also difficult to be supplied to the inside of the culture medium, which inhibits the respiration of the hyphae. For this reason, the culture period becomes long, the growth of shiitake mushrooms is inhibited, and it is difficult to obtain high-quality shiitake mushrooms.

Second, when removing a culture medium from a cultivation container, it is necessary to invert the cultivation container. Therefore, equipment such as a reversing device is required, which increases the equipment cost (and also makes it difficult to remove the culture medium), which also has disadvantages such as damaging the culture medium.

The present invention solves the problems that exist in the conventional technology, and aims to provide a mushroom cultivation container that allows high quality mushrooms to be obtained and that makes it extremely easy to take out the medium from the cultivation container. be.

[Means to solve the problem]

In constructing a bottomed cylindrical mushroom cultivation container 1 having an opening 2 at the upper end from which the culture medium A stored therein can be taken out, the present invention is particularly directed to a mushroom cultivation container 1 that is located approximately in the center of the bottom 3 and located closer to the opening 2 than the opening 2. It is characterized in that it is provided with a small vent portion 4 and a breathable sheet material 5 made of, for example, kraft paper, which closes the vent portion 4 from the inside.

[For production]

According to the mushroom cultivation container 1 according to the present invention, the vent portion 4 formed approximately in the center of the bottom portion 3 is closed from the inside by the air-permeable notebook material 5, so that the culture medium A is not allowed to enter the cultivation container 1. Even when the container is housed, the medium A does not leak out from the vent portion 4, and the container can be used as a normal cultivation container.

On the other hand, since the sheet material 5 has air permeability, carbon dioxide is discharged from the inside of the cultivation container 1 to the outside through the ventilation port 4, and on the other hand, oxygen is supplied from the outside to the inside, and the bottom surface of the cultivation container 1 Respiration of medium A on the side is promoted.

Moreover, when taking out the culture medium A from the cultivation container 1, a push-out member such as a round bar may be inserted from the outside of the vent part 4, and the medium A can be easily taken out from the opening part 2. At this time, since the culture medium A can be held with a chuck or the like, there is no need to invert the cultivation container 1.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described in detail based on the drawings.

First, the structure of the cultivation container 1 will be explained with reference to FIGS. 1 and 2.

The cultivation container 1 is formed into a bottomed cylindrical shape consisting of a cylindrical part 6 and a bottom part 3, and has an opening 2 at the upper end from which the culture medium A stored therein can be taken out. Such a cultivation container 1 can be integrally molded from plastic or the like. The cylindrical portion 6 is formed with a slight taper that gradually becomes larger in diameter as it goes from the bottom 3 side to the opening 2 side, and the space between the bottom 3 and the cylindrical portion 6 is rounded to form a curved surface. .

Further, the bottom part 3 has a vent part 4 having a diameter smaller than the diameter of the opening part 2 (for example, about 1y3) approximately in the center thereof.
will be established. On the other hand, a stopper 7X protruding in the radial direction is integrally formed at an intermediate position in the vertical direction on the outer peripheral surface 6s of the cylindrical portion 6, and a similar stopper 7y is also integrally formed at a lower position. Each of the stoppers 7X, 7y may be formed in a ring shape over the entire circumference of the outer circumferential portion 6S, or may be formed in a plurality of positions dotted at predetermined intervals.

On the other hand, a sheet material 5 made of air-permeable kraft paper is prepared, placed in the cultivation container 1, and the vent portion 4 is closed from the inside. Note that the size of the sheet material 5 is formed to be sufficiently larger than the vent portion 4.

In addition, 10 is a cap, which covers the opening 2 by covering the upper end of the cultivation container 1. The cap 10 has an uneven surface on its inner surface, and when placed on the cultivation container I, forms a predetermined gap with respect to the cultivation container 1 to ensure ventilation.

Next, a method for cultivating shiitake mushrooms including the functions of the cultivation container 1 will be described with reference to FIGS. 3 to 5.

First, as shown in FIG. 3, a sterilized cultivation container 1 is filled with a medium A, and one or more inoculation holes H of a predetermined depth are provided in the contained medium A downward from the top surface. Inoculation hole H...
- Inoculate with seed fungi, cover with cap 10, and then spread mycelia in the culture room.

When the culturing process is completed, as shown in FIG. 4, the extrusion member P, which is moved forward and backward by an air cylinder or the like, is inserted into the vent section 4 from the lower surface side of the bottom section 3. This results in
Since the medium A protrudes upward from the opening 2 of the cultivation container 1, the upper part of the medium A can be grasped with a robot chuck C or the like and easily taken out. Note that a round bar or the like can be used as the extrusion member P.

At this time, there is no need to invert the cultivation container 1. In addition, the stoppers 7X and 7y of the cultivation container 1 are engaged with fixed portions (not shown), and displacement when the extrusion member P is inserted is regulated.

Then, the taken out medium A is placed on a predetermined cultivation container and cultivated in a growth chamber.

FIG. 5 shows medium A containing shiitake mushroom M.

Although the embodiments have been described in detail above, the present invention is not limited to these embodiments.

For example, mushrooms are not limited to shiitake mushrooms, but can be applied to all types of mushrooms. Moreover, this does not preclude the case where the cultivation container is inverted when taking out the cultivation container.

In addition, the detailed configuration, shape, size (dimensions), material, etc. may be arbitrarily changed without departing from the gist of the present invention.

〔Effect of the invention〕

As described above, the mushroom cultivation container according to the present invention is provided with a vent portion smaller than the opening at the top end approximately at the center of the bottom portion, and is provided with an air permeable notebook material that closes the vent portion from the inside. Therefore, the following remarkable effects are achieved.

■ Through the vents and notebook material provided at the bottom of the cultivation container, the respiration of mycelia in the medium on the bottom side is particularly promoted, shortening the cultivation period, promoting the growth of shiitake mushrooms, and producing high-quality mushrooms. (Shiitake mushrooms) can be obtained.

■ There is no need to invert the cultivation container when removing the culture medium from the cultivation container, eliminating the need for equipment such as an inversion device.
