Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray for loading mushroom culture containers capable of efficiently and labor-saving cultivation of mushrooms such as shiitake mushrooms and maitake mushrooms using a mushroom culture container formed of a plastic bag.

[0002]

2. Description of the Related Art In order to culture mushrooms, besides the traditional method using a wood tree, a mushroom culture container such as a plastic bag, a plastic bottle or a glass bottle using a medium mainly composed of wood flour such as sawdust or rice bran. There is a method of culturing inside. Particularly, plastic bags are widely used in recent years because they are lightweight and easy to handle. As a representative example, Japanese Utility Model Publication No. 57-22518
Part of the plastic film has a pore size of 0.02
A mushroom fungus culture bag made of a film that is a porous plastic film of about 0.4 μm has been proposed. Hole diameter 0.0
The 2-0.4 μm porous plastic film prevents invasion of various bacteria without impeding the flow of air necessary for growing mushrooms. Specifically, the pore diameter is 0.02 × 0.2 μm or 0.0
A 4 × 0.4 μm microporous polypropylene film (trade name: Duragard; manufactured by Celanese Corporation, USA) is used.

[0003] In a mushroom culture container formed of such a plastic bag, a nutrient base (wood flour such as sawdust and rice bran as a main component) for culturing the mushroom is filled and sterilized by heating, and then the fungus is inoculated. Steam is usually used for heat sterilization, but when the amount of nutrient base is 2.5 kg, the temperature and temperature are reduced to 95 to 98 ° C. for 7 to 8 hours, including high and low temperature, and 12 hours for high pressure sterilization.
It takes about 5 hours at 0 to 125 ° C. In order to perform heat sterilization, a mushroom culture vessel is placed on a sterile shelf of a mushroom culture vessel or a mushroom culture vessel with a hole having a diameter of about 10 mm, and steam is introduced from below to perform treatment under the above conditions. The heat-sterilized mushroom culture vessel is moved to an inoculation room provided in another place, inoculated with mushrooms, and then moved to a mushroom culture shelf in a culture room provided in another place and cultured for several weeks. If the mycelium is sufficiently propagated in the nutrient base, there is no need to worry about contamination by various bacteria. Therefore, open the upper part of the container (plastic bag) to grow mushrooms on the surface of the nutrient base.

In the culture using a mushroom culture container, 1) filling the container with a nutrient group, 2) moving the container filled with the nutrient group to a sterilization room, 3) placing the container on a shelf of a heat sterilizer,
4) Remove the sterilized container from the shelf of the heat sterilizer. 5)
Move the sterilized container to the inoculation room, 6) Inoculate the mushroom fungus, 7) Move the inoculated container to the culture room, 8) Place the container on the culture shelf, 9) Not required after mushroom harvest Repeated transfer, loading and unloading operations, such as removing used containers from the culture shelf, 10) moving used containers to the disposal site, and 11) separating and discarding used nutrient bases and containers. There is a need to do. The nutrient group to be filled in one mushroom culture container is usually 2.
Since the weight is 5 to 3.0 Kg, the above work becomes heavy labor and requires a lot of manpower.

[0005] It has been proposed to carry out mushroom cultivation by loading a plurality of mushroom culture containers on a tray. However, in order to consistently carry out from heat sterilization to culture of mushrooms and harvest of mushrooms, it is necessary to carry out heat sterilization. It is necessary that the distribution of water vapor be rapid and uniform, that the mushroom fungi be well ventilated during culture and propagation, and that there be sufficient space for mushroom growth and harvesting. Insufficient flow of steam or air between the adjacent mushroom culture vessels loaded on the tray will increase the heat sterilization time and the growth period of the mushroom fungi, resulting in poor productivity.

[0006]

SUMMARY OF THE INVENTION The object of the present invention is to efficiently and labor-saving a mushroom culture using a mushroom culture vessel which can handle a plurality of mushroom culture vessels simultaneously, has a good flow of steam and air, and has a good mushroom culture vessel. It is an object of the present invention to provide a tray for loading a mushroom culture container capable of performing the above method.

[0007]

The tray for loading a mushroom culture container according to the present invention has a box shape having a substantially quadrangular bottom plate and side plates provided around the bottom plate, with the bottom plate having a substantially inverted U-shape. A partition band formed by bulging into the bottom plate and dividing the bottom plate into a plurality of partitions, a number of openings provided at the upper portion of the partition band, and a plurality of partitions divided by the partition band from the height of the partition band from the bottom plate in each of the plurality of partitions. A mushroom culture vessel loading area formed by protruding into an approximately quadrangular trapezoidal shape with a low height, a number of openings provided on the entire surface of the mushroom culture vessel loading area, and an end of the bottom plate from an intermediate height between the side plates. It is characterized by being a plastic integral molded article having a large number of openings provided in the range.

FIG. 1 is a plan view illustrating a tray 1 for loading a mushroom culture container according to the present invention, and FIG. 2 is a side view as viewed from the A side in FIG. FIG. 3 is a cross-sectional view taken along line BB of FIG. The tray for loading the mushroom culture container of the present invention is a molded plastic article, which is basically a box having a substantially quadrangular bottom plate 2 and a side plate 3 provided around the bottom plate. , A partition band 4 formed by bulging in an inverted U-shape to divide the bottom plate into a plurality of sections, a large number of openings 5 provided above the partition band, and a bottom plate in each of the plurality of sections divided by the partition band. From the mushroom culture vessel loading area 6, which is formed to protrude into a substantially quadrangular trapezoidal shape having a height lower than the height of the partition band, a number of openings 7 provided on the entire surface of the mushroom culture vessel loading area, and the side plate. It has a number of openings 8 provided from an intermediate height to the end of the bottom plate.

[0009] The partition band 4 is provided one in the vertical direction of the bottom plate 2 and at least one in the horizontal direction. For example, when one partition strip is provided in the vertical direction and one partition strip in the horizontal direction, the bottom plate 2 is divided into four sections, and when one partition strip 4 is provided in the vertical direction and two strips in the horizontal direction, The bottom plate 2 is divided into six sections. The installation position of the partition band is determined so that the shape and the size of each section are the same. In this way, the partition band 4 divides the tray into a plurality of sections, and also functions as a rib for increasing the strength of the tray. A large number of openings 5 are provided above these partition bands 4. This is to facilitate the flow of steam in the sterilization chamber and the flow of air in the culture chamber. The partition band 4 may be connected from one end to the other or may be partially discontinuous.

In each of the plurality of sections divided by the partition band 4, there is provided a mushroom culture vessel loading area 6 formed by raising the bottom plate into a substantially quadrangular trapezoid having a height lower than the height of the partition band. Further, a large number of openings 7 are provided on the entire surface of the mushroom culture vessel loading area 6. Since the mushroom culture vessel loading area 6 is raised in a trapezoidal shape (see FIG. 3), when the mushroom culture vessel loading tray 1 is set on a shelf plate in a sterilization chamber, the mushroom culture vessel loading area 6 becomes a shelf. It is in a state of floating at some distance from the board. The distance, that is, the height at which the mushroom culture vessel loading area 6 is raised from the level of the bottom plate 1 is suitably in the range of 1 to 10 mm. Since there is a space between the shelf plate and the mushroom culture vessel loading area 6, there are a large number of openings 7 on the entire surface, so that during heat sterilization, steam uniformly contacts the bottom and side faces of the loaded mushroom culture vessel, and the partition band. The heat sterilization time can be shortened in combination with the water vapor from the large number of openings 5 provided on the upper part of the upper part 4. If the height at which the mushroom culture vessel loading area 6 is raised from the level of the bottom plate 1 is less than 1 mm, the uniform distribution of water vapor is insufficient. Although there is no particular upper limit for this height in terms of action, no special effect is recognized even if this height is made 10 mm or more. Similarly, when placed on a shelf in a culture room, the air flow is extremely good, preventing the metabolism of mushrooms from being damaged and preventing the mushrooms from growing unevenly due to local heat buildup. it can.

Further, a number of openings 8 are provided from an intermediate height of the side plate 3 to an end of the bottom plate 2. The openings 8 not only promote the flow of water vapor and air, but also facilitate the reuse of the tray. Since the bottom of the tray for loading the mushroom culture container has an uneven bottom surface and dust easily accumulates in the recess, the dust collected in the corner of the tray is easily discharged from the opening 8 when the tray is washed with water when reused. You. It is preferable that the upper portion of the side plate 3 is formed so as to be folded into an inverted U shape to form the upper edge portion 31. This is to increase the strength of the tray.

[0012]

As described above, since a plurality of mushroom culture vessels can be handled at the same time, mechanization becomes easy, and since the flow of steam and air is good, sterilization of nutrient groups and mushroom culture can be performed efficiently and labor-saving.
