Description

Mushroom cultivation system using countercurrent

The present invention relates to a mushroom cultivation system using countercurrent, and more particularly, to a mushroom cultivation system for cultivating mushrooms with a mushroom medium in a mushroom cultivation container placed on a mushroom tray provided in multi-layer rows inside a mushroom grower. By adjusting the intake and exhaust inside the grower, a warm air flow is formed by counter-current from the top to the bottom, and the appropriate growth air is uniformly supplied to each medium of the mushroom grower to create a counter-current that enables more efficient mushroom growth. It relates to a mushroom cultivation system used.

In general, mushrooms grow well in damp and shaded places, and in recent years, efforts are being made to enable mass production using mushroom growers, which are separate cultivation facilities such as plastic greenhouses, for aquaculture.

In a plurality of mushroom cultivation containers placed on a multi-layered mushroom shelf provided inside the mushroom grower, a mushroom culture medium containing a mushroom spawn is placed, and the temperature and humidity inside the facility are maintained at a constant level to ensure good mushroom growth. .

On the other hand, during the growth of mushrooms in the mushroom grower, the temperature is generated due to the growth of the mycelium, and when the mycelium grows, latent heat is accumulated in the medium, which adversely affects the growth of the mycelium. Therefore, when the latent heat in the medium is discharged to the outside by artificially controlling the flow of air, an upward airflow is inevitably formed due to the heated air.

Moreover, when the flow of airflow is controlled through exhaust and airflow, the flow of airflow inevitably flows biasedly by convection, and even when air is controlled at constant temperature or constant humidity, it grows toward the medium in the mushroom grower made of multi-layered shelves. There is also a problem in that the air is not evenly spread, which greatly impedes the growth of mushrooms.

In addition, as the mushroom grows, the closed cultivation facility is different from the open field, and the temperature rises, so ventilation is required. Alternatively, in a temperature environment that is too hot in summer, there is a limit to simple ventilation, so the cooling fan is operated.

In other words, the temperature of the grower who grows mushrooms requires a temperature of about 10-15℃ or higher regardless of the season, so the burden of heating and cooling costs is the biggest problem because the temperature must be controlled by using an air conditioner in summer and a heater in winter. It is currently emerging as a

As shown, the mushroom cultivation system 100 using countercurrent flow according to an embodiment of the present invention contains a mushroom medium in a plurality of mushroom cultivation containers placed on a mushroom tray provided inside the mushroom grower 50 and provides a countercurrent flow. A mushroom cultivation system for cultivating mushrooms using an air supply duct 51 formed in the upper center side by side in the longitudinal direction and discharging and supplying relatively warm growth air in the downward direction; and two branched air exhaust ducts 52 formed opposite to each other in the longitudinal direction on the lowermost inner side of the first mushroom cultivation shelf and the second mushroom cultivation shelf 53 to suck the exhaust air of the mushroom cultivation thread 50 . ) is included.

Here, the air supply duct 51 communicates with the first air conditioning chamber 20 and the second air conditioning chamber 30 to be described later to the outside of the mushroom grower 50 to receive relatively warm air (growth air) exchanged with geothermal heat. The two branched air exhaust ducts 52 are merged into one air exhaust duct 52 and communicate with a third air conditioning chamber 40 to be described later to the outside of the mushroom grower 50 .

That is, the mushroom grower 50 is normally heat-exchanged with external air and geothermal heat through the air supply duct 51, as will be described later, so that appropriate warm growth air that is reduced or heated according to the season is introduced, and for the generation of white flowers The air raised to 25-30°C (humidity 90-99%) through the heater unit and the low-temperature and dehumidified air are alternately supplied through the moisture sensing unit 31 .

In addition, the mushroom grower 50 discharges the exhaust air through the air exhaust duct 52, but communicates with the second air conditioning chamber 40, so that heat recovery of the exhaust air is possible as described above.

Here, mushrooms grow from a mushroom cultivation container 54 placed on a mushroom cultivation shelf 53 provided in the mushroom grower 50 , and the mushrooms generally contain a mushroom medium in the mushroom cultivation container 54 and air supply duct 51 . It is to grow from the medium by placing the environmental conditions such as temperature, humidity, and illuminance in the right state through relatively warm suitable growth air (14-17 degrees) that has been heat-exchanged with external air and geothermal heat.

On the other hand, during the growth of mushrooms, the temperature is generated due to the growth of the mycelium, and latent heat is generated in the mushroom medium, which adversely affects the growth of the mycelium, and it must be discharged to the outside.

However, in general, the internal air of a typical mushroom grower 50 is warm air rises and cold air descends by convection phenomenon, and the latent heat in the medium rises upward by the warmed air and the flow of airflow is biased. Even if the proper growth air is supplied through the conventional air supply duct, it is not uniformly supplied to the multi-layered mushroom grower's medium, which greatly hinders the growth of mushrooms.

However, in the present invention, the air supply duct 51 for supplying relatively warm growth air (14-17 degrees) is long formed in the upper center of the mushroom grower 50 and discharged to the lower side, and two symmetrically branched The air exhaust duct 52 is formed at the lower side of the mushroom grower 50 with a length of the center as a reference to force the exhaust air to be sucked in, so that relatively warm air in the mushroom grower 50 is supplied with the air supply duct 51 at the upper side. By allowing it to flow downward through the two branched air exhaust ducts 52 below, countercurrent naturally occurs inside the mushroom grower (actually, the upper supply air temperature is about 14-17 degrees, the growth air temperature). , and the temperature of the exhaust air sucked in from the lower side rises to about 4 degrees in consideration of latent heat, and it becomes about 18-21 degrees, which is sucked in).

Here, the temperature of the air supplied through the air supply duct 51 installed on the upper side of the mushroom grower is approximately 14-17 degrees as appropriate growth air heat-exchanged with geothermal heat, as will be described later, but the temperature of the growth air It should be understood that the range is not limited, and the range is not limited as long as it is a temperature suitable for mushroom growth (approximately 10-25° C.), and is warm enough to generate a countercurrent downward as in the present invention. .

More specifically, in the mushroom grower 50, as shown in FIGS. 2A to 2C, two mushroom cultivation shelves formed in upper and lower multi-layered rows are arranged to face each other in the longitudinal direction with respect to the center, In the upper center, an air supply duct 51 is formed to be long in parallel in the longitudinal direction, and two symmetrically branched air exhaust ducts 52 to be opposite to each other are long in the lowermost inner side of the two mushroom tray shelves in the longitudinal direction. is formed

Here, the end of the ball supply duct 51 formed long in the longitudinal direction at the upper center of the mushroom grower 50 communicates with the second air conditioning chamber 30 and is relatively warm through heat exchange with external air and geothermal heat, as will be described later. Appropriate growth air is introduced, and the ends of the two branched air exhaust ducts 52 opposite to each other around the center are merged into one duct as described above inside the lowermost inner side of the two shiitake shelves, and the third air conditioning room It communicates with (40) so that the sucked exhaust air can be discharged after recovering waste heat.

A plurality of intake air outlets 51-1 are formed to be spaced apart from the lower part of the air supply duct 51 formed in the upper center in the longitudinal direction in the mushroom grower, and appropriate growth air (approximately 14-) exchanged with geothermal heat is formed downward. 17 degrees) is discharged, and in the outer side (in the opposite direction to the outside) of the two branched air exhaust ducts 52 formed to be opposite to each other about the center inside the lowermost inner side of the two mushroom tray shelves, a plurality of spaced apart of the exhaust air intake 52-1 is formed.

As described above, relatively warm appropriate growth air (14-17 degrees) is forcibly discharged downward (opposed to be disposed through a plurality of intake air outlets of the air supply duct 51 formed in the upper center of the mushroom grower 50) (discharge downward toward the first mushroom cultivation shelf and the second mushroom cultivation shelf 53, etc.) formed in a multi-layered row, and a plurality of two branched air exhaust ducts 52 formed inside the lowermost part of the mushroom cultivation yarn 50 Through the exhaust air intake, air (including latent heat) that has passed through the first mushroom cultivation shelf and the second mushroom cultivation shelf 53 formed in upper and lower multi-layer rows is sucked in (the temperature of the suctioned exhaust air is approximately 4 degrees in consideration of latent heat) It is possible to adjust the air flow of the downward airflow rather than the rising of the warm air by the form of the discharge with a rise of approximately 18-21 degrees). By inhaling the exhaust air that has passed through the formed two mushroom cultivation racks, etc., from the bottom side, countercurrent is generated. Efficient mushroom growth becomes possible (see Fig. 2a).

In addition, a plurality of intake air outlets 51-1 formed at a plurality of spaced apart from the lower portion of the air supply duct 51 can independently or entirely control the downward discharge angle, so that the mushroom cultivation shelf 53 is formed widely in upper and lower multi-layer rows. ), the supply control (supply amount) of the appropriate growth air to suit the medium characteristics of each group of mushrooms in the mushroom cultivation container 54 arranged in a plurality of groups can be selectively or entirely made (see FIG. 2b ). )

Of course, the plurality of intake air outlets 51-1 can each independently control the amount of growth air, and these angle adjustments and emission control can be integrated by the mushroom cultivation controller 60 to be described later.

In addition, in the mushroom grower 50 of the present invention, since warm air flows from the upper side to the lower side due to the counter-current flow, even if the door (not shown) of the mushroom grower 50 is opened, the outside of the door is more cold air. Since the natural convection flowing downward is generated, the outside air is introduced and does not mix, so that even if the door of the mushroom grower 50 is actually opened, the outside air does not flow at all.

3 is a schematic explanatory diagram illustrating air supply and discharge flows of a mushroom cultivation system using countercurrent according to an embodiment of the present invention, and FIG. 4 is a first view of a mushroom cultivation system using countercurrent according to an embodiment of the present invention. It is a schematic illustration showing an air conditioning room, and FIG. 5 is a schematic illustration showing the second and third air conditioning chambers of the mushroom cultivation system using countercurrent according to an embodiment of the present invention.

As shown, the mushroom cultivation system 100 using countercurrent according to the embodiment of the present invention includes a geothermal supply unit 10 buried underground to supply geothermal heat, and a first air conditioning room 20 in which external air exchanges heat with geothermal heat. ), a second air conditioning chamber 30 that communicates with the first air conditioning chamber and supplies air that has been dehumidified by introducing air from the first air conditioning chamber to a mushroom grower, and a third air conditioning chamber 40 that recovers waste heat by exchanging heat with the exhaust air, and It is made to further include a mushroom grower 50 to which air of the first air conditioning room 20 is supplied.

In the mushroom cultivation system 100 using countercurrent according to the embodiment of the present invention, first, growth air, which is air formed at a predetermined temperature for mushroom growth, as air in the mushroom grower 50, is used as a separate hot air fan as in the prior art. The air heat-exchanged by the geothermal heat is supplied through the air supply duct 51 through the first air conditioning chamber 20 or the third air conditioning chamber 40 in which external air is heat-exchanged with the geothermal heat without the need to operate a separate device. Therefore, there is a low-power operation such that excessive power consumption is not generated.

Therefore, looking at the 'growing air' mentioned above, it is the air in the mushroom cultivation facility, and in order for mushrooms to grow, the temperature is 15 to 25 ℃ in summer (humidity: about 80 to 95%), and in the case of winter, It is necessary to keep the temperature at 10-18°C.

Here, in the mushroom cultivation system 100 using countercurrent according to the embodiment of the present invention, the geothermal supply unit 10 is buried underground to supply geothermal heat and the first air conditioning chamber 20 in which external air exchanges heat with geothermal heat. In the case of use, in the case of summer, when the high-temperature external air of 37 ° C passes through the first air conditioning chamber 20 that exchanges heat with geothermal heat, the temperature can be reduced to about 16 to 17 ° C. Also, in the case of winter, when the cold and hot external air of -15 ° C passes through the first air conditioning chamber 20 that exchanges heat with geothermal heat, it can be heated to about 14 to 15 ° C. can be supplied within.

The geothermal supply unit 10 is buried underground and generates and supplies geothermal heat through heat exchange with geothermal heat. ), the geothermal line 11 through which water flows is installed in a zig-zag form or a matrix form to achieve uniform heat exchange with geothermal heat.

In fact, the geothermal line 11 may be installed in a zigzag form or a matrix form in a square box of approximately 90 cm×85 cm and buried underground.

The geothermal line 11 is preferably provided with corrugated stainless steel in order to increase the insulating area, and one end of the geothermal line 11 is connected to the geothermal water supply hose 12 through the geothermal water pump 13 . The geothermal water flow of the first inlet air temperature controller 22 is supplied to the geothermal water flow line 24 of the first inlet air temperature controller 22 to be described later, and the other end is the geothermal water flow of the first inlet air temperature controller 22 through the geothermal water discharge hose 14 . It is connected to the line 34 so that geothermal water can be supplied with reduced or heated geothermal water depending on the season while circulating the geothermal water through the geothermal supply unit 10 and the first inlet air temperature control unit 22 .

Here, the geothermal water supply hose 12 and the geothermal water discharge hose 14 are also preferably made of a corrugated stainless pipe in order to increase the insulating area.

The first air conditioning chamber 20 is formed with an external air intake unit 21 for sucking external air on one side, and communicates with the geothermal supply unit 10 on the other side to be sucked through the external air intake unit 21. The first inlet air temperature control unit 22 that exchanges heat with geothermal heat as the outside air passes is formed.

The external air intake unit 21 is formed on one side of the first air conditioning chamber 20 to introduce external air into the first air conditioning chamber. Here, a foreign matter filter unit for removing foreign substances from the external air may be further formed in the external air intake unit.

As shown in FIG. 4 , the first inlet air temperature control unit 22 is configured to reduce the temperature of the geothermal line between a plurality of air flow holes 23 through which the introduced external air flows, and the air flow holes 23 . Alternatively, it is made including a geothermal water flow line 24 through which heated water flows.

The first inlet air temperature control unit 22 may have a configuration similar to that of a radiator for dissipating heat from an engine such as a vehicle. That is, low-temperature cold water supplied from the outside flows through the water flow path as a plurality of cold water tubes, and a heat dissipation fin for improving heat exchange may be provided around the cold water tubes. And a through hole (air flow hole) through which air flows is formed between these cold water tubes (water flow path line) and heat dissipation fins for heat exchange. Accordingly, the air passing through the first inlet air temperature control unit 22 exchanges heat with the cold water tube and the heat dissipation fin of the water flow path. It will be warmed or cooled to a temperature at which it is in super thermal equilibrium.

That is, the geothermal water flow line 24 is connected to the geothermal water supply hose 12 and the geothermal water discharge hose 14 shown in FIG. It is connected to the geothermal line 11 so that water that has been reduced or heated by geothermal heat can be circulated, so that external air flowing to the right through the air flow hole 23 is naturally heat-exchanged with geothermal heat to reduce or warm the temperature as described above. In the case of the case, when the high temperature external air of 37 ° C passes through the air flow hole 23 of the first air conditioning room 20 that exchanges heat with geothermal heat, the temperature can be reduced to 16-17 ° C, and in winter, the temperature of -15 ° C. When the cold and hot external air also passes through the air flow hole 23 of the first air conditioning room 20 that exchanges heat with geothermal heat, it can be heated to 14 to 15 ° C. will be able to do

In this way, the geothermal heat exchange air that has been reduced or warmed to an optimal temperature by exchanging heat with the geothermal air is connected to the second air conditioning room 30 through the geothermal heat exchange air supply duct 25 (refer to FIG. 3) through a pump (not shown). to supply the geothermal heat exchange air into the second air conditioning chamber 30 .

In addition, a heater unit (not shown) is installed in the first air conditioning chamber 20 to further heat the geothermal heat exchanged air to be heated. Such a heater unit is required to increase the internal temperature of the mushroom grower 50 to 25-30° C. (humidity 90-99%) for the formation of white flowers of mushrooms (especially shiitake mushrooms). Of course, such a heater unit can be operated to adjust the temperature of the mushroom grower if necessary in addition to the formation of white flowers.

The heating of the heater unit is made possible by, for example, heating water contained in the lower part of the first air conditioning chamber to further warm and humidify the geothermal heat exchanged air and supply it to the inside of the mushroom grower 50 .

As shown in FIGS. 3 and 5 , the second air conditioning chamber 30 receives geothermal heat exchange air through the first air conditioning chamber 20 and the geothermal heat exchange air supply duct 25 and heat exchanged air by geothermal heat. to be supplied to the mushroom grower 50 through the air supply duct 51 .

On the other hand, in the second air conditioning room 30, on one side, the internal temperature of the mushroom grower 50 raised to 25-30 ° C (humidity 90-99%) by the heater unit installed in the first air conditioning room 20 is formed as a whitewash. For this purpose, it further includes a moisture-reducing unit 31 for supplying to the mushroom grower 50 by rapidly reducing the temperature and simultaneously reducing the moisture.

That is, when the internal temperature of the mushroom grower 50, which has risen to 25-30°C (humidity 90-99%), is rapidly reduced to 15°C or less to form a white flower, the humidity of the mushroom grower 50 is further increased by condensation. It rises, making it difficult to form white flowers, but by supplying air that has been rapidly reduced in temperature by the moisture sensing unit 31 installed in the second air conditioning room 30 to the mushroom grower 50, 45-55% at 15° C. or less By creating an environment to maintain the humidity of

The moisture sensing unit 31 includes a plurality of air flow holes 32 through which the introduced external air flows, and a refrigerant storage line 33 through which cold water and refrigerant are stored and flowed between the air flow holes 32 .

The high-temperature air passing through the moisture-reducing unit 31 is cooled by heat exchange while passing through the refrigerant storage line 33 , and at the same time, it is dehumidified by the generation of condensed water, and the temperature is reduced to the mushroom grower 50 through the air supply duct 51 . Whitening occurs naturally by supplying fresh air to bring the humidity from 25 to 30 ° C (humidity 90-99%) to about 45-55% at 15 °C or lower rapidly.

As shown in FIG. 5 , the third air conditioning chamber 40 is connected to the air exhaust duct 52 to supply exhaust air, and an exhaust air heat recovery temperature control unit that exchanges heat with the exhaust air as the exhaust air passes. (41) is further provided.

The exhaust air heat recovery temperature control unit 41 includes a plurality of exhaust air flow holes 42 through which the introduced exhaust air flows, and the heated water exchanged with the exhaust air communicates between the air flow holes to provide heat recovery water. It includes a flow line (43).
