Below, the humidity control of being undertaken by humidity conditioner 2 is specifically described.The block diagram that Fig. 3 controls for the humidity that expression an embodiment of the invention relate to.When 1 entry into service of aeration type solid culturing device, to controlling organization 12 input humidity set point.Humidity set point is for example selected in the scope of relative humidity 94～99%.If then solid culture 5 is difficult for dry in this scope.
In the running of aeration type solid culturing device 1, to the hygroscopy value of controlling organization 12 inputs from humidity sensor 11.As humidity sensor 11, can enumerate the humidity sensor that adopts the wet-dry thermometer by the difference mensuration humidity of dry-bulb temperature and wet-bulb temperature to form.In addition, be not limited to this, the humidity sensor that can also form for the method for using adsorptive capacity with water vapour to be converted to resistance or electrostatic capacitance.
Controlling organization 12 possesses output calculation section 19.Output calculation section 19 is based on humidity set point with from the deviation of the hygroscopy value of humidity sensor 11, output control output.Control is output as the instruction for the work number of increase and decrease humidification nozzle 13.In addition, as described in rear explanation, humidification nozzle 13 is during with group part cell formation, for the group some work that is used for making selection work, make and select the idle group of idle instruction of part.
Control output for controlling organization 12, if for example hygroscopy value is greater than humidity set point, its poor humidity set point+5% with interior scope in, then make the work number of humidification nozzle 13 reduce by 1 control output for being used for, if in+5%～+ 10% scope, then make the work number of humidification nozzle 13 reduce by 2 control output for being used for.In contrast, if the hygroscopy value is less than humidity set point, its poor humidity set point-5% with interior scope in, then make the work number of humidification nozzle 13 increase by 1 control output for being used for, if in-5%～-10% scope, then make the work number of humidification nozzle 13 increase by 2 control output for being used for.
The increase and decrease of the work number of humidification nozzle 13, as shown in Figure 1, valve 16 that can be by being arranged at water service pipe 14 and the switch that is arranged to the valve 17 of tracheae 15 carry out.According to the signal from controlling organization 12, the valve 16 of each humidification nozzle 13 of switch and valve 17.Among Fig. 1, the dotted line expression signal line that is connected with controlling organization 12.For convenient diagram, the signal wire of valve 16 and valve 17 is only illustrated one, other omission.
In air regulator 10, humidification nozzle 13 work corresponding to the number of exporting from the control of controlling organization 12 generate humidifying air.And the humidity in the downstream of air regulator 10 is measured by humidity sensor 11, and the hygroscopy value feeds back to controlling organization 12.Calculation method as output calculation section 19 can use common calculation method.For example can calculate the instruction of exporting for the work number of increase and decrease humidification nozzle by PID control, the sample value control calculation that also can utilize intermittent mensuration and calculation and export.If the situation of sample value control calculation, consider air residence time, humidity sensor 11 reaction times then the control interval it is desirable to more than 10 seconds, for example be 1 minute.After, Yi Bian repeat the flow process of above-mentioned control, Yi Bian carry out humidity control so that the hygroscopy value is humidity set point.
In the present embodiment, the particle diameter by the water droplet of each humidification nozzle 13 sprayings is redefined for necessary size, even the number of the humidification nozzle 13 of increase and decrease work also can maintain the particle diameter of the water droplet of spraying in certain scope.That is, even increase the number of humidification nozzle 13, the particle diameter of the water droplet of spraying can not increase yet, and also can prevent is increased by the ratio that water eliminator 18 separates.In addition, even reduce the number of the humidification nozzle 13 of work, the particle diameter of the water droplet of spraying can not reduce yet, and can prevent that the reduction of spray amount from exceeding required.
Therefore, in the control of the humidity of present embodiment, when maintaining the particle diameter of the water droplet of spraying in certain scope, the work number of increase and decrease humidification nozzle 13, therefore the increase and decrease of the work number of humidification nozzle 13 is directly reflected as the increase and decrease of spray amount, can realize accurately humidity control.In addition, controlling organization 12 is inputted the measured value of the humidity sensor 11 in the downstream that is arranged on air regulator 10, calculates control output.In this structure, even cause the humidity of the air supplied with to change owing to the variation of the temperature of extraneous gas, humidity, air output, the corresponding therewith measured value of humidity sensor 11 also can change, and therefore directly calculates the control output corresponding to the variation of the humidity of the air of supplying with.So, in the humidity control of present embodiment, not being subject to the impact of extraneous gas, air output, this also helps accurately humidity control.The effect of the humidity control of these present embodiments can obtain confirming in the embodiment of following explanation.
In the structure of Fig. 4, humidification nozzle 13 is to organize part unit selection work or not work.For the 1st group of part～the 4th group of part, select respectively work or do not work, if make at least one group some work that the work number of humidification nozzle 13 is changed in 1～10 scope.Only partly select work for the 1st group, when partly selecting not work, the work number is 1 for the 2nd group of part～the 4th group.If for two group part selection work of the 1st group of part and the 4th group of part, partly to select not work for the 2nd group of part and the 3rd group, the number of working is 5.If for whole selection work of the 1st group of part～the 4th group of part, the number of then working is 10.In addition, also can be certain structure for the 1st group of part～the 4th group of idle situation of whole selections partly.In this structure, the work number of humidification nozzle 13 can change in 0～10 scope.
The structure of Fig. 4 is an example, and the number of the humidification nozzle 13 that contains in the configuration of humidification nozzle 13, each group part etc. are appropriate change as required.In addition, in the structure of Fig. 1, humidification nozzle 13 separates predetermined distance formation multiple row at the air supply direction of air.In the structure of Fig. 4, each group part can separate predetermined distance and dispose as the structure of Fig. 1, also can dispose at grade.By this configuration, can prevent that water droplet by humidification nozzle 13 spraying from colliding with pipe arrangement or other humidification nozzle 13 and form draining.This also is not same with the situation of group part cell formation for a plurality of humidification nozzles 13.
More than, in the above-described embodiment, be illustrated with structure shown in Figure 1 as the aeration type solid culturing device, but as long as aeration type solid culturing device 1 is not limited to the structure of Fig. 1 the device for solid culture 5 is blown and cultivated.In addition, as long as humidification nozzle 13 is for can with the structure of water droplet spraying, being not limited to second fluid nozzle.

The Sauter mean diameter of the water droplet that humidification nozzle 13 is sprayed: 40 μ m
The 1st group of part: 1 of nozzle number
The 2nd group of part: 2 of nozzle numbers
The 3rd group of part: 3 of nozzle numbers
The 4th group of part: 4 of nozzle numbers
Nozzle number: amount to 10.
Bent closely in order to confirm easily effect, use the mycelia of cultivating the 22nd hour to extend, form the state that air output easily reduces, with extraneous gas 100% suction and discharge of drying, the state entry into service that is reduced by the humidity in the device intentionally.Further after 2 hours, carry out Song Qu, make closely Qusong loose, form the state that air output easily rises.The initial value of the extraneous gas during the running beginning is as follows.
Dry-bulb temperature: 30.0 ℃
Wet-bulb temperature: 22.0 ℃
Relative humidity: 50%.
Dry-bulb temperature sensor and wet bulb temperature sensor are set as temperature sensor 11 under the bed in the downstream of air regulator 10, confirm humidity over time.Fig. 5 represents that relative humidity changes along with time lapse.After about 15 minutes, relative humidity is stable, periodically changes in 94～96% scope.During this time, the work number of humidification nozzle 13 is in 5～7 scope.Relative humidity when stablizing is essentially 95%, confirms the variation of the air output that embodiment can cause corresponding to the temperature of extraneous gas, humidity, by the tight situation of song, can carry out accurately humidity control.Song after running is finished is not found the piece that drying, excess moisture cause, and is good state.
(comparative example)
Except embodiment, comparative example is also carried out experimental verification.Comparative example uses the control method of record in the above-mentioned patent documentation 3.In the comparative example, measure temperature and humidity at the upstream side of damping device, by air output and the required spray amount of humidification efficiency calculation of the air of supplying with, the control service pump is to spray this spray amount.Among Fig. 1, the measured value of humidity sensor 11 in the downstream side of air regulator 10 is not used in the control of comparative example.For experiment condition, except the value of in advance set air output and humidification efficiency, identical with embodiment.The value of air output and humidification efficiency is as follows.
Air output: 350m
3/ minute
Humidification efficiency: 80%.
For easy affirmation effect in comparative example, use the song identical with embodiment, form the state that air output easily reduces, with extraneous gas 100% suction and discharge of drying, the state entry into service that is reduced by the humidity in installing intentionally.Further after 2 hours, carry out Song Qu, make closely Qusong loose, form the state that air output easily rises.With embodiment similarly, dry-bulb temperature sensor and wet bulb temperature sensor are set as temperature sensor 11 under the bed in the downstream of air regulator 10, confirm humidity over time.When beginning running the relative humidity in downstream of air regulator 10 identical with extraneous gas, be 50%.The initial value of the extraneous gas of the upstream side of air regulator 10 is as follows.
Dry-bulb temperature: 30.0 ℃
Wet-bulb temperature: 22.0 ℃
Relative humidity: 50%
Absolute humidity: 0.013kg/kg.
The set(ting)value in the downstream side of air regulator 10 is as follows.
Dry-bulb temperature: 22.6 ℃
Wet-bulb temperature: 22.0 ℃
Relative humidity: 95%
Absolute humidity: 0.016kg/kg
Specific volume: 0.86m
3/ kg
Blew quality: 407kg/ minute.
In the comparative example, try to achieve the spray amount that forms above-mentioned set(ting)value with calculation.According to above-mentioned value, the absolute humidity that replenishes by humidification is 0.016-0.013=0.003kg/kg.Spray amount is 407 * 0.003 * (100/80)=1.5L/ minute.Experiment has just begun rear control service pump so that this spray amount is sprayed.Fig. 6 represents that relative humidity changes along with time lapse.Along with time lapse, relative humidity surpasses set(ting)value 95% until pine is bent, reduces behind the pine song on the contrary.The excess moisture of the lower floor of the song after running is finished, drying and consolidating, or stick on the bed board.Think that this is because air output and humidification efficiency are not tried to achieve normal solution in calculation, and because the variation of the tight situation of loose Qu Qianhou song although the fluctuation of actual air output is not reflected in the calculation, therefore can not be carried out accurately humidity control.
