It is a typical explanatory drawing which shows the harvesting process in the said cultivation method of mushrooms. It is a typical explanatory view of a part of the equipment used in the method of cultivating mushrooms.

The present invention will be specifically described below. However, the present invention is not limited to the form of this embodiment.

The fungus bed connection sheet of the present invention has a plurality of fungus beds used for cultivating mushrooms and is connected to each other in a row. It is a method of manufacturing by almost automating the The method for cultivating mushrooms of the present invention is a method for culturing a mushroom bed using the above-described mushroom bed connection sheet to grow the number of mushrooms. Examples of the mushrooms include shiitake mushrooms, enoki mushrooms, shimeji mushrooms, maitake mushrooms, and oyster mushrooms. Moreover, in the present invention, the fungal bed means a fungal bed medium in a state of being sealed in a container after being inoculated. Further, the term "sealing" means sealing so as to prevent the invasion of germs while not impeding the breathing of mushrooms.

In general, in order to cultivate mushrooms using a container such as a cultivation bottle, first, a container such as the cultivation bottle is filled with a fungal bed medium raw material, and the whole container is heat-sterilized to obtain a fungal bed medium. Inoculate mushroom spawn. The inoculated fungal bed medium is sealed to prevent the intrusion of germs and the like, and becomes a fungal bed. Next, this fungal bed is cultured in a culture chamber until the mycelium spreads in the fungal bed (ripened fungal bed), and after the seal is released in the growth chamber, the fungal bed is grown until harvested as a fruiting body. be. Cultivation (cultivation and growth) of mushrooms in the present invention is generally carried out according to this flow. However, the present invention is significantly different from the conventional method in that a rigid container such as a cultivation bottle or an individual container such as a plastic bag is not essential.

<Mushroom bed connection sheet>
As shown in FIGS. 1(a) and 1(b), for example, in the fungal bed connection sheet according to one embodiment of the present invention, a plurality of fungal beds 13 are arranged in rows by a container body 8 and a sealing resin 9. Concatenated. FIG. 1(a) is a plan view of the fungal bed connecting sheet as viewed from above, and FIG. 1(b) is an XX cross section thereof. In FIG. 1(a), since the resin film 11 of the sealing resin 9 is transparent, the fungal bed culture medium 6 located thereunder can be seen.
In this manner, the plurality of fungus beds 13 are connected to each other without the adjacent container bodies 8 being separated, and are continuously sealed by the sealing resin 9 . . In addition, since the resin film 11 is translucent, it is possible to secure sufficient illumination for culturing the fungus bed 13 with respect to the surface of the fungus bed medium 6 .

The container body 8 of the mushroom bed 13 is formed by forming a bottom film 5 made of a flexible resin by a deep draw packaging machine (see FIG. 3). Examples of the flexible resin include polyolefin and polystyrene. , polycarbonate, nylon, polyethylene, epoxy resin, polypropylene, ethylene-vinyl alcohol copolymer resin, etc., and these can be used alone or in combination of two or more. Further, the bottom film 5 may be provided with a single layer or a plurality of layers made of these materials.

The thickness of the bottom film 5 is not particularly limited as long as the flexibility of the container body 8 can be ensured, but it is usually 50 to 1000 μm, and preferably 80 to 500 μm from the viewpoint of weight reduction. , more preferably 100 to 300 μm, still more preferably 150 to 250 μm. In the present invention, the flexibility of the container main body 8 is ensured because if the container main body 8 is lifted while containing the fungal bed medium 6, the fungal bed medium 6 collapses and cannot maintain its shape. It means that the container body 8 itself deforms to a certain degree, and is different from hard plastic products (e.g., planters and containers) that can maintain the shape of the fungal bed medium 6 housed inside even when lifted. means In addition, the bottom film 5 preferably has a light-shielding property from the viewpoint of preventing mushroom growth from unexpected places.

The size of the container body 8 (corresponding to one mushroom bed 13) is not particularly limited, but from the viewpoint of the size of the cultivation facility and the ease of handling, for example, the width and length are It is preferably 100 to 1000 mm, more preferably 200 to 800 mm, even more preferably 300 to 500 mm. The width and length of the container body may be the same or different. The height of the container body is not particularly limited, but the gap (head space S) (see FIG. 1) between the fungal bed medium 6 and the sealing resin 9 is set to a predetermined size. From the viewpoint of facilitating the operation, for example, it is preferably 30 to 500 mm, more preferably 40 to 400 mm, even more preferably 50 to 300 mm. If the head space S is provided so that the space between the fungal bed medium 6 and the sealing resin 9 maintains a constant shape, the maturing of the fungal bed 13 is accelerated, and the entire fungal bed 13 is brought into a uniform state more quickly. can spread mycelium.

The sealing resin 9 has flexibility and is formed of a ventilation filter 10 and a resin film 11 made of a flexible resin, the majority of which normally has translucency. The ventilation filter 10 is not particularly limited as long as it allows air to pass through but can prevent invasion of germs. Examples of the resin film 11 include polyolefin, polystyrene, polycarbonate, nylon, polyethylene, epoxy resin, polypropylene, ethylene-vinyl alcohol copolymer resin, etc. These can be used alone or in combination of two or more. Further, the resin film 11 may be provided with a single layer or a plurality of layers made of these materials. Furthermore, the ventilation filter 10 may be preliminarily formed into a sealing tape shape. In this case, the adhesion work to the resin film 11 can be made easier.

The method of adhering the ventilation filter 10 and the resin film 11 is not particularly limited. In the case of a seal tape, it may be adhered using its adhesive layer. In addition, it is preferable that the ventilation filter 10 is overlapped and adhered from the surface of the resin film 11 that does not face the fungal bed culture medium 6 . By doing so, it is possible to suppress excess moisture from being contained in the ventilation filter 10, and there is a tendency that it is possible to further prevent the invasion of germs, and to ensure more air permeability. In addition, the area in contact with the fungal bed medium 6 and the hyphae of mushrooms can be reduced, and there is a tendency that the propagation of various germs on the aeration filter 10 itself can be suppressed.

The thickness of the sealing resin 9 is not particularly limited as long as its flexibility can be ensured, but the thickness of the resin film 11, which occupies most of it, is usually 30 to 1000 μm. From the viewpoint of drawing, the thickness of the resin film 11 is preferably 50 to 300 μm, more preferably 50 to 100 μm. The flexibility of the sealing resin 9 conforms to the flexibility standard of the container body, and is different from rigid plastic products (eg, planter lids, container lids).

In addition, as shown in FIGS. 2A and 2B, the sealing resin 9 does not have a flat film shape, and the space (head space S) between the fungal bed medium 6 and the sealing resin 9 when sealed. ) may be formed in such a manner that a convex portion is provided toward the outside. If the thickness (height) of the fungal bed medium is constant, there is a tendency that the larger the headspace S, the higher the yield of mushrooms. From the point of view of ensuring more head space S, it is preferable that the convex portion of the sealing resin 9 is formed entirely in a convex portion facing the container body 8 . In this way, if the entire portion facing the container body 8 is formed as a convex portion, the head space S can be secured even if the fungal bed medium 6 is accommodated up to the height of the container body 8. The upper end and the upper surface of the fungal bed medium 6 can be flush with each other, and the harvesting blade of the harvesting tool can be easily brought into contact with the roots of the mushrooms at the time of harvesting the mushrooms. Since the fungal bed medium 6 tends to expand due to cultivation and growth, the top surface of the fungal bed medium 6 is often higher than the upper end of the container body 8 when mushrooms are harvested. , It becomes even easier to apply the harvesting blade to the last minute of the root of mushrooms.

When the sealing resin 9 is shaped to have convex portions facing outward, the sealing resin 9 itself is three-dimensionally molded, so it is preferable that the sealing resin 9 has a certain thickness. Specifically, the thickness of the sealing resin 9 is preferably 50 to 1000 μm, more preferably 80 to 500 μm, still more preferably 100 to 300 μm from the viewpoint of weight reduction.

The height of the headspace S in the container body (the distance H from the mushroom bed medium 6 to the sealing resin 9) is such that the harvesting blade of the harvesting tool can be applied to the very bottom of the mushrooms, and the entire mushroom bed 13 is is preferably 10 to 100 mm, more preferably 15 to 90 mm, even more preferably 20 to 80 mm, from the viewpoint that the distance does not become too large. When the sealing resin 9 has a convex shape, the highest point of the convex (where the distance H from the fungal bed culture medium 6 to the sealing resin 9 is maximized) is taken as the height.

The thickness of the fungal bed medium 6 contained in the container main body is not particularly limited, but from the viewpoint of securing a certain amount of the height of the container main body and the head space S, it is preferably 10 to 400 mm, for example. , 20 to 300 mm, more preferably 30 to 200 mm.

In the above-described embodiment, the plurality of fungus beds 13 are connected to each other in rows by the container body 8 and the sealing resin 9. may have been This is because the effect of the mushroom bed connection sheet of the present invention can be exhibited if either one is connected. However, when a plurality of fungus beds 13 are connected by both the container body 8 and the sealing resin 9, there is a tendency that the work of manufacturing the container body 8 and unsealing the fungus beds 13 becomes easier. .

<Manufacturing method of fungus bed connection sheet>
For example, an apparatus shown in FIG. 3 can be used to manufacture a fungus bed-connected sheet having a plurality of fungus beds 13 according to one embodiment of the present invention. This apparatus comprises a deep draw packaging machine 1 that continuously manufactures a container body 8 having an opening on the upper surface, a medium supply device 3 that fills the container body 8 with a sterilized fungal bed medium 6, and a A pressing machine 4 (first pressing machine 4a, second pressing machine 4b) is attached to apply pressure from above to the surface of the filled inoculated fungal bed medium 6 to remove the air inside. . In the figure, 2 is a sterilization blender for producing the fungal bed medium 6. FIG.

The deep drawing packaging machine 1 feeds out the resin bottom film 5 in the direction indicated by the arrow P in FIG. A mold 7 continuously molds a container body 8 having an open top from the bottom film 5, and a sealing mold 17 is used to fill the container body 8 with the inoculated fungal bed medium 6 on the downstream side thereof. , the upper opening of which can be continuously sealed with the sealing resin 9 . As the deep draw packaging machine 1, a machine that is widely used for packaging processed livestock products such as ham and sausages, fish paste products, and agricultural products may be employed.

More specifically, the deep drawing packaging machine 1 includes a first unwinding roll 5a around which the bottom film 5 can be wound, a molding die 7, and a roll conveyor (not shown) that conveys the container body 8. , a sealing die 17, a second unwinding roll 10a, and a third unwinding roll 11a. , the container body 8 is continuously deep-drawn into the shape of the container body 8 (in conjunction with the unwinding of the roll 5a), and the obtained container body 8 is conveyed downstream by the roll conveyor. In addition, the sealing resin obtained by stacking and integrating the ventilation filter 10 unwound from the second unwinding roll 10a and the resin film 11 unwound from the third unwinding roll 11a in a predetermined arrangement. 9 is arranged so as to cover the upper opening of the container body 8, and the upper opening is continuously sealed (top sealed) with the sealing resin 9 using a sealing mold 17. As shown in FIG.

In order to sterilize the sealing resin 9 used for sealing the upper opening of the container body 8, a UV sterilizer 12 is provided so as to face the inner peripheral surface of the container body 8. As shown in FIG. In the figure, 15 is a nip roll for the bottom film 5 and 16 is a nip roll for the ventilation filter 10 or the sealing resin 9 .

On the other hand, the culture medium supply device 3 for filling the fungal bed medium 6 into the container main body 8 formed in the deep draw packaging machine 1 includes a belt conveyor and a screw conveyor for conveying the fungal bed medium 6 sterilized in the sterilization blender 2. etc., the inoculation machine 3a for inoculating mushroom seed fungi into the mushroom bed medium 6 being transported, and the transported inoculated fungus bed medium 6 is filled from the top opening of the container main body 8. and a filling nozzle 3b. As the inoculation machine 3a, for example, one having a function of injecting a predetermined amount of sawdust into the fungal bed medium 6, or an aqueous solution of the inoculum adjusted to a predetermined concentration uniformly on the surface of the fungal bed medium 6. and those having a function of spraying into the air. As the filling nozzle 3b, for example, a general-purpose automatic filling device for measuring a predetermined amount of fungal bed or the like and filling the container main body 8 with the same can be used.

After the container main body 8 is filled with the inoculated fungus bed medium 6, as shown in FIG. A press 4 is attached to press the surface. The pressing machine 4 includes a first pressing machine 4a and a second pressing machine 4b. It has become.

A sealing die 17 is provided on the downstream side of the pressing machine 4. With this sealing die 17, the upper opening of the container body 8 after being pressed is covered with a sealing resin 9 and sealed. is to be carried out. That is, the sealing mold 17 heat-seals the sealing resin 9 stacked in such a manner as to close the top opening, and continuously seals the container bodies 8 that are successively conveyed and sent out. .

Using such a device, for example, by passing through the following steps (1) to (4), a plurality of fungus beds 13 (inoculated fungus bed medium 6 are stored in the container body 8 in a sealed state. ) are connected to each other in a row to obtain a fungal bed-connected sheet. In this embodiment, all the steps up to (3) the top sealing step are performed in a clean room. In addition, the bottom film 5, the sealing resin 9, and the like are sterilized in advance by gas sterilization such as ethylene oxide gas sterilization (EOG sterilization) or γ-ray irradiation. Only the exposed portion is further sterilized using a UV sterilizer 12 or the like. Since the container body 8 is thermoformed by the molding die 7 and the sealing resin 9 is heat-sealed, both are in a state of being sterilized by heat.

(1) Container main body supply step The bottom film 5 is unwound from the first unwinding roll 5a of the deep drawing packaging machine 1, and the recesses are continuously formed in the bottom film 5 by the molding die 7 disposed in the middle. It is a step of molding and supplying the concave portion to the process as a container body 8 having an opening on the upper surface. As a result, the container body 8 is connected to each other without being cut individually, and the bottom film 5 is aligned in the length direction (in series) on the roll conveyor (Fig. not shown).

That is, in this step, since the container body 8 is sent out onto the conveying path by continuously forming recesses in the bottom film 5 by the deep drawing packaging machine 1, the sterilized container body is individually prepared and stored. It is possible to realize low cost by eliminating the trouble such as. In addition, since the container body 8 can be sterilized quickly and strictly, it is possible to reliably suppress the contamination of various germs in the cultivation of mushrooms. In addition, since the container bodies 8 are connected to each other without being cut individually, they can be efficiently delivered onto the conveying path while being arranged in series.
In addition, the above-mentioned serial shape means all of those arranged in a row, and includes not only those arranged in one row but also those arranged in a plurality of rows. Further, the conveying path means the conveying path itself for conveying the container body 8, and does not necessarily need to be configured by a roll conveyor.

Since the container bodies 8 are connected to each other without being cut, there is no need for each container body 8 to stand on its own. good too. If the container main body 8 is formed of a thin film or a highly flexible resin film, the container main body 8 itself is lightweight and can be easily transported. easier. Although the thickness of the resin film used for the container body 8 is not particularly limited, it is preferably 100 μm or more from the viewpoint of durability.

In addition, the bottom film 5 used for the container body 8 is preferably made of a light-shielding resin film because it can prevent the primordium of the fruiting body from being formed on the side or bottom surface of the container body 8 . When a resin film having no light-shielding property is used as the bottom film 5, it is preferable to cover the portion other than the top opening of the container body 8 with a light-shielding film or outer container.
In the present invention, the resin film used for the bottom film 5 and the sealing resin 9 refers to a flexible flat resin having a thickness that can be taken up, and the thickness is not critical.

(2) Medium filling step In the step of filling the inoculated fungal bed medium 6 from the upper opening using the medium supply device 3 to the container main body 8 sent out on the roll conveyor and conveyed downstream. be. For example, the sterilized fungal bed medium 6 produced by the sterilizing blender 2 is inoculated with mushroom spawn by the inoculating machine 3a during transportation. Next, the inoculated fungus bed medium 6 is continuously filled into the inside of the container body 8 from the top opening by the filling nozzle 3b. Thereby, the fungus bed 13 can be produced efficiently. In this embodiment, the mushroom bed medium 6 is inoculated with (shiitake mushroom spawn).
The fungal bed medium 6 may be filled while the container body 8 is being transported, and the container body 8 does not necessarily need to be filled while the container body 8 is in motion. For example, the container body 8 may be transported intermittently, and the fungal bed medium 6 may be filled at the timing of the stop.

(2-1) Pressing step After the medium filling step (2), the surface of the inoculated fungal bed medium 6 filled in the container body 8 is pressed using the press 4 or the like. . By pressing the fungal bed medium 6, the shape and thickness of the fungal bed medium 6 can be adjusted, and the spreading speed of mycelia in the fungal bed culturing (ripening) step described later can be accelerated. The above-described pressing can be repeated. In this embodiment, as shown in FIG. 3, pressing is performed by the first pressing machine 4a and then pressing is performed by the second pressing machine 4b. By repeatedly pressing the surface of the fungal bed medium 6, the retention of its shape can be enhanced. By increasing the retention of the fungal bed medium 6, there is a tendency to prevent the fungal bed 13 from uncontrolled swelling due to the spreading of mycelium, and as a result, the yield of mushrooms obtained can be increased. In general, the air contained in the fungal bed 13 is approximately 30 to 50% by volume of the entire fungal bed medium 6, so that the air is sufficiently distributed to the internal mycelium.

(3) Top sealing step While conveying the container body 8 filled with the inoculated fungal bed medium 6 to the downstream side, the upper opening of the container body 8 is sealed with a sealing resin 9 using a sealing mold 17. is a step of heat-sealing and sealing. As a result, a fungus bed-connected sheet having a plurality of fungus beds 13 can be obtained continuously and efficiently.

As the sealing resin 9, for example, as shown in FIG. 4(a), a resin film 11 and an air-permeable filter 10 may be laminated and integrated. As the sealing resin 9, a resin film 11 having through-holes 11b provided at predetermined intervals is prepared in advance, or a resin film 11 having through-holes 11b provided at predetermined intervals in the course of transportation is used in the direction of the white arrow in FIG. , and the ventilation filter 10 (see FIG. 4(c)) is moved in synchronization with the running of the resin film 11, and the through hole 11b is closed (the place indicated by the broken line in FIG. 4(b)). It can be continuously formed by stacking and adhering with .
As the air-permeable filter 10, it is usually preferable to use a material that is air-permeable but impermeable to general germs. As the resin film 11, a film having translucency but little or no air permeability is usually preferably used.

(4) Take-out/send-out process To take out the obtained fungus bed connecting sheet having a plurality of fungus beds 13 from the downstream side of the deep drawing packaging machine 1 and directly use it for culturing the fungus bed 13 and growing mushrooms. It is a process to provide as a product. Alternatively, the obtained fungal bed connecting sheet having a plurality of fungal beds 13 is sent to a culture chamber for spreading mycelium, and the fungal bed 13 is cultured and mushrooms are grown as it is to harvest mushrooms. It is a process of providing. Either process may be selected.

By going through the above series of steps, automation can be achieved from the introduction of the container body 8 to be filled with the fungal bed medium 6, and the fungal bed 13 capable of cultivating high-quality mushrooms can be produced at a low cost. And it can be manufactured in a short time. In addition, since the fungus beds 13 of the obtained fungus bed connecting sheet are individually sealed and connected to each other, even in the unlikely event that they are contaminated with various germs, only the contaminated fungus beds 13 can be removed so that the entire fungus bed can be removed. Contamination can be prevented from spreading and loss can be kept to a minimum. Furthermore, when the container body 8 has a light-shielding property and the majority of the sealing resin 9 has a light-transmitting property, only the surface of the fungal bed medium 6 is given high illuminance in the culturing/raising process. A hyphal layer can be developed only on the surface of the fungal bed medium 6, and there is a tendency that mushrooms can be generated only on the surface of the fungal bed medium 6.

In the present embodiment, (1) in the container main body supply step, the container main bodies 8 are connected to each other without being individually cut, but the container main bodies 8 are sent out onto the conveying path in a state of being arranged in series.
