[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mushroom cultivation room and a method for controlling the mushroom cultivation room.

[0002]

2. Description of the Related Art In the artificial cultivation of mushrooms, the cultivation room is set to an appropriate environmental condition in accordance with the growth stage of the mushroom. Since the environmental conditions at this growth stage vary considerably depending on each growth stage, conventionally, for example, a cultivation room is separately provided for each growth stage, and a cultivation bottle is transferred to the cultivation room according to the growth stage for growth. Room temperature, humidity, ventilation, light irradiation, etc. are important factors in mushroom cultivation conditions. Therefore, in the conventional mushroom cultivation room, coolers, heaters, humidifiers, ventilation fans, lighting equipment, etc. are provided, and the operation of these devices is controlled by timer settings etc. to manage temperature and humidity etc. to predetermined conditions. ing.

[0003]

By the way, since mushroom cultivation is carried out all year round, external conditions vary variously depending on the season. In the mushroom cultivation room, since the air is exchanged with the outside air by ventilation or the like, external conditions have various influences on the environmental conditions of the mushroom cultivation room. It is desirable that the mushroom cultivation room is always set to a constant condition regardless of external conditions.
When the external conditions change in this way, it is difficult to maintain the constant conditions by only appropriately controlling the operation of management equipment such as a cooler and a heater.

The outside air temperature, the humidity of the outside air, etc. vary greatly depending on the season. For example, cold and dry outside air enters in winter, and hot humid air enters in summer.
Even though the temperature is relatively low in the morning and evening during the day, high temperature outside air enters during the day. In this way, external conditions vary widely both seasonally and even during the day, and even if they are managed while monitoring the cultivation room using temperature sensors, etc., the control cannot keep up and is constant. Maintaining the conditions is actually very difficult. This is because, for example, when outside air is introduced while keeping it at a constant temperature, the humidity decreases when dry outside air enters, and when hot air enters, the temperature rises and humidity also fluctuates. The cause is that environmental conditions fluctuate in relation to each other. Since the quality of mushrooms is greatly influenced by the conditions of the cultivation room, maintaining the cultivation room in a suitable environment is extremely important in mushroom cultivation. Therefore, the present invention has been made to solve the above problems, the place of the purpose of the mushroom cultivation room and mushroom cultivation room that can be easily set and managed in environmental conditions suitable for mushroom cultivation To provide a control method.

[0005]

The present invention has the following constitution in order to achieve the above object. That is, in a mushroom cultivation room in which mushrooms are grown by setting environmental conditions such as predetermined temperature, humidity, and carbon dioxide concentration according to the growth stage of mushrooms, aeration is performed between the cultivation room and the cultivation room. In addition to providing an environment adjustment room that communicates with the outside, the temperature and humidity of the environment adjustment room according to the environmental conditions in the cultivation room,
Providing control means to set environmental conditions such as carbon dioxide concentration,
A circulation means for circulating air between the environment adjustment room and the cultivation room is provided. Further, in a control method of a mushroom cultivation room that maintains the mushroom cultivation room in environmental conditions such as predetermined temperature, humidity, and carbon dioxide concentration according to the growth stage of the mushroom, between the cultivation room and the cultivation room adjacent to the cultivation room. An environment adjustment chamber that communicates with the outside while being ventilated with, is set to environmental conditions such as temperature, humidity and carbon dioxide concentration in the environment adjustment chamber according to the environmental conditions in the cultivation room, and the environment adjustment chamber and the above It is characterized in that the cultivation room is managed under a predetermined environmental condition by mutually circulating air with the cultivation room.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is an explanatory view showing a structure of a main part of an embodiment of a mushroom cultivation room according to the present invention, and FIG. 2 is an explanatory view showing an overall shape of the mushroom cultivation room. As shown in FIG. 2, the mushroom cultivating room 10 of this embodiment is cultivated by installing a partition plate 12 as a wall surface of the cultivation room and a ceiling partition plate 14 as a ceiling surface in a cultivating ridge 11 whose side shape is a kamaboko shape. It is formed by forming a room space. Reference numeral 16 is a cultivation shelf provided in the cultivation room for placing cultivation bottles and the like.

The cultivation ridge 11 of the example was formed by a roof deck having a corrugated outer surface. It can be formed easily and at low cost by using a roof deck and forming it into a semi-cylindrical shape. When the partitioning plate 12 and the ceiling partitioning plate 14 are attached to form the cultivation room space as described above, the cultivation ridge 11 is inevitably shaped like a kamaboko, and thus the cultivation room 1 is inevitable.
An empty space is formed on the side of the partition plate 12 of 0. This empty space is used as the environment adjustment room 18 in the embodiment. The environment adjustment chamber 18 is provided in a lateral part of the cultivation chamber 10 so as to communicate with the entire length.

FIG. 1 shows the cultivation room 10 and the environment control room 1.
8 shows the configuration in detail. Cultivation room 10 and environment adjustment room 18
Are separated from each other by a partition plate 12, and an upper ventilation port 20 and a lower ventilation port 2 are provided at an upper portion and a lower portion of the partition plate 12, respectively.
2 is provided. The upper vent 20 is an opening for sending air from the environment adjusting chamber 18 to the cultivation room 10, and the lower vent 20 is an opening for sending air from the cultivation room 10 into the environment adjusting room 18. is there. The upper ventilation port 20 is provided with a blower fan 24 for circulating air between the environment adjustment chamber 18 and the cultivation chamber 10.

An air supply port 26 and an exhaust port 28 for exchanging air between the outside of the cultivation ridge 11 and the environment control chamber 18 are provided on the outer wall of the environment control chamber 18. Reference numeral 30 is a motor fan for supplying air from the air supply port 26 into the environment adjusting chamber 18. Further, 32 is a boiler used for sterilizing the medium, and a heating unit 34 connected to the boiler 32 is installed in the environment adjusting chamber 18. A control means such as the heating unit 34 is provided in the environment adjusting chamber 18 so that the inside has a predetermined temperature and humidity environment. Therefore, the outer wall of the environment adjusting chamber 18 is covered with a heat insulating material 36 to form a heat insulating structure. Further, a cooler 38 and a water injection nozzle 40 are provided, and a sensor 42 for monitoring temperature, humidity, carbon dioxide concentration, etc. is provided. A cooler 44, a water jet nozzle 46, and a sensor 48 for monitoring temperature and humidity in the cultivation room 10 are also provided in the cultivation room 10.

In the mushroom cultivating method of this embodiment, an environment adjusting chamber 18 is provided adjacent to the mushroom cultivating chamber 10 and air is passed through the environment adjusting chamber 18 when the cultivating chamber 10 and the outside air are exchanged. It is characterized by flowing through. As shown in FIG. 1, the environment adjustment chamber 18 communicates with the outside of the cultivation ridge 11 through an air supply port 26 and an exhaust port 28, but the cultivation chamber 10 does not directly communicate with the external space, and the environment adjustment chamber 18 It is designed to communicate to the outside via. Therefore, the inside of the cultivation room 10 can be set to the required conditions by setting the inside of the environment adjustment room 18 to the environmental conditions such as a predetermined temperature and humidity.

The temperature, humidity and the like in the environment adjusting chamber 18 are controlled by controlling the water injection from the heating section 34 or the cooler 38 connected to the boiler 32 and the water injection nozzle 40. Ventilation between the environment adjustment room 18 and the cultivation room 10 is performed by sending air from the upper ventilation port 20 into the cultivation room 10 by a blower fan 24 and exhausting the air from the lower ventilation port 22 to the environment adjustment room 18. As described above, since the air supply and exhaust to and from the cultivation room 10 are performed between the cultivation room 10 and the environment adjustment room 18, the temperature and humidity inside the cultivation room 10 can be controlled by appropriately setting the conditions such as temperature and humidity inside the environment adjustment room 18. Environmental conditions can be controlled appropriately.

The space capacity in the cultivation room 10 is the environment adjustment room 18
Since it is much larger than the above, the temperature and humidity are controlled by operating the cooler 44, the water injection nozzle 46 and the like in the cultivation room 10 as well. In this way, the cultivation room 10 is maintained in a constant growth environment condition by the combined management of the cultivation room 10 and the environment adjustment room 18. In the conventional maintenance and management of environmental conditions in the mushroom cultivation room, when the outside of the cultivation room is ventilated, outside air is directly taken into the cultivation room, so the environmental conditions in the cultivation room are greatly affected by the external conditions. It was On the other hand, in the case of the method of the present embodiment, since the cultivation room 10 always exchanges air with the environment adjustment room 18, the outside air does not directly enter the cultivation room 10 and the external environment does not occur. Such changes do not have a direct effect, and it is possible to minimize changes in environmental conditions.

The environment adjustment chamber 18 has an air supply port 26 and an exhaust port 28.
Since it communicates with the external space via the external environment, the environment adjustment room 18 may have external fluctuations. However, if a certain indoor space is secured as the capacity of the environment adjustment room 18, hot air may enter from the outside. Even so, a constant temperature control is possible.
As a method for preventing hot air from entering the environment adjusting chamber 18, for example, a method of injecting water outside the environment adjusting chamber 18 and using heat of evaporation of water to lower the external temperature of the environment adjusting chamber 18 may be used. It is valid. Compared to the conventional case where hot air enters directly into the cultivation room 10,
The environment adjustment room 18 serves as a buffer part, and the influence on the cultivation room 10 can be effectively suppressed.

Since the environment adjusting room 18 is set so as to control the temperature, humidity and the like according to the environmental conditions of each cultivation room 10, the conditions are appropriately set according to the growth stage of the mushroom. When setting the cultivation rooms separately according to the growth stage of mushrooms such as cultivation room, sprouting room, growth room, etc., install the environment adjustment room 18 separately for each cultivation room, and correspond to each cultivation room Then, the temperature and humidity in the environment adjusting room 18 are managed, and air is exchanged with each environment adjusting room for each cultivation room. For example, the humidity in the cultivation room during the growth stage
When it is set to 90% or more, the humidity is raised even in the environment adjustment room 18, and high-humidity air is sent into the cultivation room.

As described above, in the method of the present invention, when controlling the growth environment such as temperature and humidity in the cultivation room, the environment adjustment room 18 for controlling the temperature and humidity is provided adjacent to the cultivation room 10, and the cultivation room 10 is provided. Ventilation is performed only between the environment control room 18 and the environment control room 18, and cultivation is performed while suppressing the influence of external fluctuations on the cultivation room 10 even if the external temperature, humidity, etc. fluctuate greatly during the season or during the day. It becomes possible to maintain the environmental conditions in the chamber 10 at constant conditions. With such a configuration, even when the inside of the cultivation room 10 is ventilated, the temperature, humidity, etc. do not change significantly, and it is possible to easily maintain suitable environmental conditions.

In the above-mentioned embodiment, the cultivation ridge 11 is formed in a semi-cylindrical shape as shown in FIG. 2, but the cultivation ridge 11 does not necessarily have to be a semi-cylindrical shape. It is only necessary to provide an environment adjustment chamber adjacent to the cultivation room 10 for air exchange with the cultivation room 10 so that the cultivation room 10 does not directly communicate with the external space. The environment adjustment chambers 18 may be provided on both sides of the cultivation room 10 as shown in FIG. 2, or may be provided on one side of the cultivation room 10. If provided on both sides of the cultivation room 10 as shown in FIG. 2, the outside temperature does not act directly on the cultivation room 10 and the environment adjustment room 1
Since 8 has a heat insulating effect on the cultivation room 10, the cultivation room 1
It is suitable for maintaining 0 environment.
