[Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-041027 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, even if it were possible to control the temperature inside the storage vessel as with conventional culture bed production equipment, the quality of the finished culture beds varied from season to season, making it difficult to stabilize the quality of the culture beds.

[0006] The present invention has been made in consideration of the above circumstances, and its problem to be solved is to provide an indoor environment conditioning method that contributes to stabilizing the quality of a culture bed, and an indoor environment conditioning system that can realize this method. [Means for solving the problem]

[0007] The present inventors have conducted extensive research and discovered the following, which led to the invention of the indoor environment control method and indoor environment control system of the present application. (1) The temperature of the containment vessel is more likely to drop due to radiant heat when the room temperature is low. (2) The lower the outdoor temperature, the easier it is for the room temperature to drop due to radiant heat. (3) The temperature inside the containment vessel varies greatly depending on the location where it is measured. (4) The temperature sensor only measures the temperature of a part of the containment vessel. (5) If the temperature inside the containment vessel is low, the microbial flora will change, affecting the quality of the culture bed.

[0008] [Indoor environment control method] The indoor environment adjustment method of the present invention is a method for adjusting the environment of a small room in which a culture bed manufacturing apparatus is installed, which acquires outdoor environmental information outside the small room and adjusts the indoor environment inside the small room based on the acquired outdoor environmental information.

[0009] In the indoor environment adjustment method, future outdoor environment information (for example, outdoor environment information at the start of production of culture medium in the culture bed production apparatus, or outdoor environment information at one or more points from the start of production to the completion of production) can be obtained as outdoor environment information, and the indoor environment within the small room can be adjusted based on that outdoor environment information.

[0010] In the indoor environment control method, one or more of the temperature, humidity and weather outside the small room can be acquired as the outdoor environment information.

[0011] [Indoor environment control system] The indoor environment conditioning system of the present invention is a system for conditioning the environment of a small room in which a culture bed manufacturing apparatus is installed, and is equipped with an indoor environment conditioning means for conditioning the indoor environment within the small room, an outdoor information acquisition means for acquiring outdoor environmental information outside the small room, and a control means for controlling the indoor environment conditioning means based on the outdoor environmental information acquired by the outdoor information acquisition means.

[0012] In the indoor environment control system, the outdoor information acquisition means can be one that can acquire future outdoor environmental information (for example, outdoor environmental information at the start of culture medium production in the culture bed production apparatus, or outdoor environmental information at one or more points from the start of production to the completion of production).

[0013] In the indoor environment control system, the outdoor information acquiring means can acquire at least one of the temperature and humidity outside the small room as outdoor environment information.

[0014] In the indoor environment control system, the outdoor information acquisition means and the control means can be connected so as to be able to communicate with each other. In this case, the control means can acquire outdoor environment information transmitted from the outdoor information acquisition means and control the indoor environment control means based on the outdoor environment information.

[0015] In the indoor environment conditioning system, the control means may be provided with a monitor displaying an operation unit that can be manually operated. In this case, the monitor may display at least one or more of an outdoor information display unit that displays outdoor environment information, an indoor information display unit that displays indoor environment information within the small room, and an apparatus information display unit that displays apparatus information related to the culture bed production apparatus. Effect of the Invention

[0016] According to the indoor environment control method and indoor environment control system of the present invention, the temperature inside the storage container (tank), which affects the quality of the culture bed, can be maintained at an appropriate temperature by adjusting the temperature of the small chamber based on outdoor environmental information outside the small chamber, thereby stabilizing the quality of the culture bed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] (Embodiment of the indoor environment control method) An example of an embodiment of the indoor environment control method of the present invention will be described with reference to the drawings. The indoor environment control method of the present invention is a method for controlling the environment of a small room 20 in which a culture bed production apparatus 10 as shown in Figures 1 and 2 is installed, and is a method for acquiring information on the environment outside the small room 20 (hereinafter referred to as "outdoor environment information") and controlling the air environment inside the small room 20 (hereinafter referred to as "indoor environment") based on the acquired outdoor environment information.

[0019] The outdoor environment information includes, for example, temperature, humidity, as well as air pressure, weather, wind speed, and wind direction. The outdoor environment information includes not only information at the time of acquisition, but also predicted information for the future (several hours). For example, the outdoor environment information (temperature, humidity, weather, etc.) at the start time of culture bed production is included. One piece of information (for example, temperature information) may be acquired, but two or more pieces of information (for example, temperature information and weather information) can also be acquired. It is preferable to acquire at least both or either one of temperature and humidity.

[0020] The outdoor environment information can be acquired using various devices such as a temperature sensor, a humidity sensor, a pressure sensor, an anemometer, an air flow meter, and an anemometer, as well as from weather forecasts provided through television, radio, weather data distribution services, etc. For example, when acquiring outdoor environment information such as the outdoor temperature, humidity, and weather several hours from now, weather forecasts provided through television, radio, weather data distribution services, etc. can be used.

[0021] The indoor environment includes temperature, humidity, air pressure, wind speed, wind direction, etc. The indoor environment is adjusted by controlling an indoor environment adjustment means 30 that adjusts the indoor environment of the small room 20. The indoor environment adjustment means 30 can be controlled without manual operation (automatically) or manually.

[0022] In this way, by acquiring outdoor environmental information and adjusting the indoor environment based on the acquired outdoor environmental information, the environment within the small chamber 20, which affects the temperature within the storage vessel 11, can be kept constant even in cold seasons, and the quality of the culture bed can be stabilized.

[0023] (Embodiment of indoor environment control system) Next, an example of an embodiment of the indoor environment conditioning system of the present invention will be described with reference to the drawings. The indoor environment conditioning system of the present invention is an environmental conditioning system for a small room 20 in which a bacterial bed production apparatus 10 is installed.

[0024] As an example, the indoor environment conditioning system shown in Figures 1 and 2 comprises a culture bed manufacturing apparatus 10 for manufacturing a culture bed, a small chamber 20 in which the culture bed manufacturing apparatus 10 is installed, an indoor environment conditioning means 30 for regulating the indoor environment within the small chamber 20, an outdoor information acquisition means 40 for acquiring outdoor environmental information outside the small chamber 20, and a control means 50 for controlling the indoor environment conditioning means 30 based on the outdoor environmental information acquired by the outdoor information acquisition means 40.

[0025] The above-mentioned mushroom bed producing apparatus 10 is an apparatus for producing a mushroom bed. In this mushroom bed producing apparatus 10, a fermented mushroom bed can be produced by promoting anaerobic fermentation or aerobic fermentation while stirring a wet substrate (cotton hulls, peat pulp, corn cobs, rice straw, peanut shells, rice husks, wheat husks, etc.). This mushroom bed producing apparatus 10 can be used to produce mushroom beds for cultivating mushrooms (decay fungi) other than mycorrhizal fungi, such as oyster mushrooms, shiitake mushrooms, maitake mushrooms, and shimeji mushrooms.

[0026] 1 and 2, an apparatus 10 for producing a culture bed is provided with a storage vessel 11, a heating means 12, a stirring means 13, a blowing means 14, a temperature sensor 15, and a controller 16 for controlling various devices constituting the apparatus 10. The storage vessel 11 is placed on a rack 17.

[0027] The storage vessel 11 is a vessel for producing a fermentation bed. As shown in Figures 1 and 2, the storage vessel 11 of this embodiment includes a vessel body 11a into which a substrate is introduced, and an upper lid 11b that is placed on the vessel body 11a. The vessel body 11a of this embodiment is a vessel that is U-shaped in cross section with an upper opening, both longitudinal end faces of which are closed by side walls, and the upper opening is configured so that it can be opened and closed by the upper lid 11b. The storage vessel 11 of this embodiment is made of stainless steel, which has high thermal conductivity.

[0028] The tank body 11a is provided with a culture bed discharge port 11c (FIG. 2) for discharging the completed culture bed to the outside. The culture bed discharge port 11c can be opened and closed with an opening and closing door. The top lid 11b is provided with a material input port 11d for inputting the substrate (material) into the tank body 11a, a water supply port 11e for introducing water (including hot water; the same applies below) supplied from a water adding means (not shown) into the tank body 11a, an air supply port 11f for introducing cold air supplied from the air blowing means 14 into the tank body 11a, an exhaust port 11g for discharging the cold air that has passed through the tank body 11a to the tank body 11a side, and a seed culture input port 11h for inputting the seed culture.

[0029] The heating means 12 is a means for heating the tank body 11a and the substrate and the like within the tank body 11a. In this embodiment, a planar heater is used as the heating means 12. The planar heater is provided along the outer surface of the tank body 11a. The planar heater can be provided on the front surface of the tank body 11a, or can be provided only on a portion of it. The heating means 12 can be something other than a planar heater. Although not shown, an insulating sheet can be installed around the periphery of the culture bed manufacturing apparatus 10 during periods of low temperature such as midwinter.

[0030] The stirring means 13 is a means for stirring the base material and the like in the storage vessel 11. As an example, the stirring means 13 shown in Figures 1 and 2 includes a rotating shaft 13a arranged along the longitudinal direction of the storage vessel 11, a plurality of stirring blades 13b held by the rotating shaft 13a, a drive motor 13M for driving the rotating shaft 13a, and a transmission mechanism 13c for transmitting the power of the drive motor 13M to the rotating shaft 13a. When the power of the drive motor 13M is turned on, the rotating shaft 13a and the stirring blades 13b rotate, and the base material and the like in the tank body 11a are stirred by the rotational force.

[0031] The air blowing means 14 (FIG. 2) is a means for supplying cooling air used for cooling the substrate and the like into the tank body 11a. In this embodiment, a spot cooler is used as the air blowing means 14. The cold air generated by the air blowing means 14 is introduced into the tank body 11a from the air supply port 11f, passes through the tank body 11a, and is exhausted from the exhaust port 11g.

[0032] The above-mentioned blowing means 14 is an example, and the blowing means 14 may be other than this. For example, a blowing means equipped with a cooling means for cooling the air in the small chamber 20 and a blower for sending the cooled air into the tank body 11a may be used. In this case, a cold air supply line may be connected to the air inlet 11f of the top cover 11b, so that the cooled air can be supplied from the cold air supply line into the tank body 11a. In order to reliably prevent the intrusion of germs and contamination of the culture medium, it is preferable to provide a filter such as a HEPA filter (High Efficiency Particulate Air Filter) on the blower.

[0033] The temperature sensor 15 is a means for detecting the temperature inside the containment vessel 11. For the temperature sensor 15, a thermocouple, a resistance temperature detector (for example, a sheath-type platinum resistance temperature detector), a thermistor, or the like can be used. In this embodiment, the temperature sensor 15 is provided on the inner surface side of the top lid 11b, between the air supply port 11f and the exhaust port 11g. The temperature sensor 15 may be provided at a location other than this. Instead of the temperature sensor 15, a water vapor sensor that detects the flow rate of water vapor inside the containment vessel 11 can also be provided.

[0034] The detection information from the temperature sensor 15 can be used to determine whether or not heating (heat conduction) by the heating means 12 is being performed appropriately. For example, if the temperature detected by the temperature sensor 15 is lower than a target temperature (e.g., 100°C), it is determined that heat conduction by the heating means 12 is not being performed appropriately. In this case, the heating means 12 can be controlled to increase the output.

[0035] On the other hand, if the temperature detected by the temperature sensor 15 is lower than the target temperature (for example, 100°C), it is determined that heat conduction by the heating means 12 is being performed properly and the moisture that has turned into water vapor has been evenly distributed throughout the base material that was concentrated at the bottom of the tank body 11a.

[0036] The controller 16 is a means for controlling various devices constituting the culture bed manufacturing apparatus 10. The controller 16 in this embodiment is provided on the front portion on the clean area 21 side of the culture bed manufacturing apparatus 10. The controller 16 can set operating conditions (time, temperature, etc.).

[0037] Although not shown in the figures, the mushroom bed manufacturing apparatus 10 of this embodiment is communicatively connected to an administrator terminal (e.g., a PC or tablet used by the administrator) used by an administrator, and is configured to enable remote control of the settings of the operating conditions of the mushroom bed manufacturing apparatus 10 as well as remotely checking the operating status of the mushroom bed manufacturing apparatus 10 and the progress of the manufacturing process.

[0038] The small chamber 20 is a room partitioned off from the outside for installing the culture bed production apparatus 10. As an example, the small chamber 20 shown in Fig. 3 is internally partitioned into a clean area 21 and an unclean area 22. In this embodiment, the culture bed production apparatus 10 and the ventilation means 14 are installed at a position spanning the clean area 21 and the unclean area 22.

[0039] An exterior wall 21a on the clean area 21 side is provided with a worker entrance 21b for workers to enter and exit the clean area 21. This worker entrance 21b can be opened and closed with a worker entrance door 21c. An opening 22b through which people can enter and exit is also provided on the exterior wall 22a on the unclean area 22 side. This opening 22b is closed with a removable panel material 22c.

[0040] The clean area 21 is provided with an indoor environment adjusting means 30 for adjusting the indoor environment in the small room 20. As described above, the indoor environment includes temperature, humidity, air pressure, wind speed, wind direction, and the like.

[0041] The indoor environment adjusting means 30 includes various means capable of adjusting the indoor environment, such as a temperature-adjustable air conditioner, a heater (e.g., sheet-shaped or panel-shaped) that prevents temperature leakage from the containment vessel 11, a circulator that eliminates temperature unevenness in the room, a ventilation fan, a positive pressure damper, and the like. One or more of these may be used in the indoor environment adjusting means 30. The heater may be installed on the outside of the tank body 11a, and the circulator may be installed on the ceiling side. Note that the drawings show only a air conditioner as an example of the indoor environment adjusting means 30.

[0042] In this embodiment, as shown in Figures 1 and 3, a plurality of supports 23 are provided on the outside of the small room 20 on the unclean area 22 side, and a dust curtain 24 for preventing dust from flying around is hung from the supports 23. The dust curtain 24 can be made of vinyl or the like.

[0043] The outdoor information acquisition means 40 is a means for acquiring outdoor environmental information outside the small chamber 20. As described above, the outdoor environmental information includes information such as air pressure, weather, wind speed, and wind direction in addition to temperature and humidity. The outdoor environmental information also includes not only information at the time of acquisition, but also predicted information for the future (several hours later or a certain period of time from several hours later). For example, the outdoor environmental information (temperature, humidity, weather, etc.) at the start time of culture bed production is included.

[0044] The outdoor environment information can be obtained using various devices such as a temperature sensor, a humidity sensor, a pressure sensor, an anemometer, an air flow meter, and an anemometer, as well as from television, radio, weather forecasts provided through meteorological data distribution services, etc. For example, to obtain the outdoor temperature, humidity, and weather several hours from now as outdoor environment information, a weather forecast provided through a meteorological data distribution service, etc. can be used.

[0045] The control means 50 is a means for controlling the indoor environment adjusting means 30 based on the outdoor environment information acquired by the outdoor information acquiring means 40. The control means 50 may be, for example, one equipped with a control unit 51, a calculation unit 52, a transmission / reception unit 53, a storage unit 54, an operation unit 55, etc., as shown in Fig. 4. The control means 50 may be built-in or external. When it is an external device, a PC (e.g., a mobile PC), a tablet, a smartphone, etc. may be used. In either case, it is preferable that the control means 50 is equipped with a touch panel monitor 56.

[0046] The operation screen displayed on the monitor 56 may include, for example, a condition input section 56a, an outdoor information display section 56b, an indoor information display section 56c, an apparatus information display section 56d, and a predicted information display section 56e as shown in Fig. 5. The operation screen does not need to include all of these, and may include one or more of them.

[0047] The condition input section 56a is a section for inputting conditions such as the production start time, the outdoor information display section 56b is a section for displaying outdoor environmental information at the current time (when the screen is operated), the indoor information display section 56c is a section for displaying indoor environmental information within the small room 20 at the current time, the equipment information display section 56d is a section for displaying equipment information related to the culture bed manufacturing apparatus 10 at the current time, and the predicted information display section 56e is a section for displaying predicted information.

[0048] 5, the condition input unit 56a has input fields for the production start time, weather, temperature, and humidity as conditions, the outdoor information display unit 56b has current weather, temperature, and humidity as outdoor environment information, the indoor information display unit 56c has current indoor temperature and humidity as indoor environment information, the device information display unit 56d has current temperature and operating state inside the containment vessel 11 as device information, and the forecast information display unit 56e has weather and temperature for each hour from the present time to several hours later as forecast information. The information displayed in the condition input unit 56a and each of the display units 56b to 56e is merely an example, and other information may be used.

[0049] The control means 50 can be configured to operate automatically upon receiving outdoor environment information transmitted from the outdoor information acquisition means 40, or can be configured to operate upon manual input of outdoor environment information. Manual input can be performed using the operation unit 55. In this case, for example, the scheduled production start time and the weather, temperature, humidity, etc. at the scheduled production start time acquired by the outdoor information acquisition means 40 can be input to the condition input unit 56a.

[0050] When the indoor environment adjustment means 30 is automatically controlled by the control means 50, for example, as shown in FIG. 6(a), after outdoor environment information is acquired by the outdoor information acquisition means 40 (S101), the outdoor environment information is transmitted from the outdoor information acquisition means 40 (S102), the outdoor environment information is received by the transmitting / receiving unit (S103), and based on the outdoor environment information, conditions for making the temperature inside the small room 20 a predetermined appropriate temperature are calculated (S104), and the indoor environment adjustment means 30 is controlled according to the calculated control conditions (S105).

[0051] For example, if the start time for production of the culture bed is 6 hours later and the preset appropriate temperature for the temperature inside the small chamber 20 is 25°C, the outdoor temperature information for 6 hours later transmitted from the outdoor information acquisition means 40 is received by the transmission / reception unit 53, and based on that temperature information, the calculation unit 52 calculates the conditions for the temperature inside the small chamber 20 to be 25°C 6 hours later (preferably from 6 hours later to the scheduled finishing (production completion) time), and the indoor environment adjustment means 30 can be controlled according to the calculated conditions.

[0052] On the other hand, when the indoor environment adjustment means 30 is manually controlled by the control means 50, for example, as shown in FIG. 6(b), after outdoor environment information is acquired by the outdoor information acquisition means 40 (S201), the outdoor environment information acquired by the outdoor information acquisition means 40 is manually input (S202). Once the input is completed, conditions for making the temperature inside the small room 20 a predetermined appropriate temperature are calculated based on the set conditions (S203), and the indoor environment adjustment means 30 is controlled according to the calculated control conditions (S204).

[0053] For example, if the start time for production of the culture bed is 6 hours later and the preset appropriate temperature for the temperature inside the small chamber 20 is 25°C, the outdoor temperature information for 6 hours later obtained by the outdoor information acquisition means 40 is set on the operation screen displayed on the monitor 56. Once the setting is complete, the calculation unit 52 calculates the conditions for the temperature inside the small chamber 20 to be 25°C 6 hours later (preferably from 6 hours later to the scheduled completion time), and the indoor environment adjustment means 30 can be controlled under the calculated conditions.

[0054] The operation of the control means 50 is one example, and the control means 50 may be operated in other ways. For example, a finish time input section (not shown) may be provided on the operation screen displayed on the monitor 56, and when a desired finish time is input into the finish time input section, control conditions for maintaining the indoor environment at a preset appropriate temperature from the production start time to the finish time are calculated from the information displayed on the outdoor information display section 56b, the indoor information display section 56c, the predicted information display section 56e, etc., and the indoor environment adjusting means 30 may be controlled under the calculated control conditions.

[0055] The embodiment described here is merely an example, and the indoor environment control system of the present invention may have other configurations. Furthermore, not all of the configurations described in this embodiment are essential, and unnecessary configurations may be omitted as appropriate.

[0056] It should be noted that the indoor environment control method and indoor environment control system of the present application maintain the environment (temperature) within the containment vessel 11 by controlling the environment within the small chamber 20, and are positioned differently from those that directly control the temperature, etc. within the containment vessel 11.
