With reference to the flow chart of Figure 5 will be described with respect to the method of hydroponic cultivation of sprouts for forage by using the hydroponic cultivation system for forage sprouts of the present invention made in this way.

First, the roughage cultivated using the hydroponic cultivation system for forage sprouts of the present invention is sprouts, but it is a system that can also hydroponic cultivation of various plants. Roughage is a feed that contains less fat, protein, starch, etc. and contains about 18% or more of fiber, such as clean grass and hay. This forage provides the nutrients needed to raise livestock and produce livestock products such as eggs, meat, milk and fur.

Moreover, in order to cultivate sprouts for forage in the hydroponic cultivation system for forage sprouts of the present invention, the operator enters and exits through the clean booth 30 of the hydroponics 10. The operator can remove contaminants attached to the worker's work clothes and body with the high-pressure air sprayed from the air shower 31 in the clean booth 30 . This is a hygiene suitable for Hazard Analysis and Critical Control Point (HACCP) to prevent biological, chemical, and physical hazards from being mixed or contaminated with sprout vegetables while growing sprout vegetables in a hydroponics (10). This is to enable the establishment of a management system.

In FIG. 5 , as a growth preparation step, impurities are removed from seeds to be sown in the workshop 32 and defective seeds are selected ( S1 ). And for the germination of the seed, it is immersed in an immersion tank filled with water and soaked for about 10 hours, and the immersed seeds are sown in the cultivation tray 21 covered with cultivation (S2).

Next, in the first growth stage, the cultivation trays 21 in which the seeds are sown are respectively loaded and installed on the cultivation tables 20 installed in a plurality of stages in the cultivation buildings 11-18 that have been disinfected (S3). At this time, in FIG. 7A , under the control of the controller 62, the lighting equipment 50 and the LED light source 51 inside the rearing building 11-18 are all turned off and the dark state is maintained for 24 hours. This is because sprouted vegetables must maintain a certain dark time during seed germination to promote germination. And by using the spray device 53 under the control of the controller 62 of the cultivation building 11-18, ultrasonic humidification is sprayed once every 6 hours for a certain period of time so that the internal humidity of the cultivation building 11-18 is 82. ~88% should be maintained. In addition, the internal temperature of the cultivation cavity 11-18 is maintained at 21.5°C. The controller 62 lowers the internal temperature by operating the fan 60 when the internal temperature of the re-creation 11-18 is 25° C. or higher, and stops the operation of the fan 60 when the internal temperature is 21.5° C. or lower (S4). ). The first growth stage should be maintained for approximately 24 hours. Accordingly, FIG. 6a shows that 24 hours have elapsed in the dark state after the seeds are sown in the cultivation tray 21 .

In the second growth stage, in FIG. 7B , the LED light source 51 is turned on for 16 hours in the cultivation building 11-18 and turns off for 8 hours. And the controller 62 operates the fan 58 for air circulation during the lighting time of the LED light source 51 so that the air inside the cultivation building 11-18 is circulated by convection. This is to control so that heat generated in the process of growing sprouted vegetables is circulated inside the cultivation building 11-18. In addition, the spray device 53 is used to spray once every 6 hours for a certain period of time so that the internal humidity of the cultivation building 11-18 is maintained at 82 to 88%. In addition, the controller 62 maintains the internal temperature of the culture building 11-18 at 21.5°C, and operates the ventilator 60 when the internal temperature of the culture building 11-18 becomes 25°C or higher. Lower the temperature and stop the operation of the fan 60 when it is 21.5° C. or less (S5). The second growth stage is maintained for approximately 48 hours. Accordingly, FIGS. 6B and 6C are photographs taken in units of 24 hours when seeds are germinated on the cultivation tray 21 .

In the third growth stage, the LED light source 51 is turned on for 16 hours in the cultivation building 11-18, and the light is turned off repeatedly for 8 hours. And the controller 62 operates the fan 58 for air circulation during the lighting time of the LED light source 51 so that the air inside the cultivation building 11-18 is circulated by convection. This is to control so that heat generated in the process of growing sprouted vegetables is circulated inside the cultivation building 11-18. In addition, the controller 62 uses the spray device 53 to spray once every 8 hours for a predetermined time so that the internal humidity of the cultivation building 11-18 is maintained at 82 to 88%. Furthermore, when approximately 4 days have elapsed after installing the seeded cultivation tray 21 in the cultivation building 11-18, it is preferable to use the spray device 53 to spray once every 8 hours for a certain period of time. And the controller 62 uses the carbon dioxide gas supply unit 59 to eject a certain concentration of powdered carbon dioxide gas to the cultivation dong 11-18, so that carbon dioxide necessary for photosynthesis of sprouted vegetables is supplied. In addition, the controller 62 maintains the internal temperature of the culture building 11-18 at 21.5° C. and operates the fan 60 to lower the temperature when the internal temperature of the culture building 11-18 becomes 25° C. or higher. , stops the operation of the fan 60 when it is 21.5° C. or less (S6). The third growth stage should be maintained for approximately 72 hours. Therefore, FIGS. 6D to 6F are photographs taken in 24 hour units of the process of growing sprouted vegetables on the cultivation tray 21 .

When the third growth step elapses in the growth preparation step, a shipping step is performed. That is, the operation of all devices installed in the cultivation building 11-18 is stopped to release the sprouted vegetables that have been grown. Then, the cultivation tray 21 in which the sprouted vegetables are grown is separated from the cultivation table 20 and then transferred to the workshop 32 using the variable conveyor 37 installed in the transfer passage 36 . In the workshop 32, the sprouted vegetables are harvested from the cultivation tray 21 and shipped out (S7). And the sprouted vegetables shipped from the workshop 32 will be able to use the loading and unloading conveyor 70 in order to be loaded on the transport vehicle. Therefore, FIG. 6g is a photograph of sprouted vegetables that have been grown on the cultivation tray 21 .

Next, in the disinfection step, when the cultivation tray 21 used for the growth of all sprouted vegetables in the cultivation building 11-18 is removed, the controller 62 uses the smoke screen sterilizer 61 to prepare a disinfectant solution of a certain concentration. The inside of the cultivation building 11-18 is disinfected by spraying a smoke screen, and the cultivation tray 21 is disinfected by immersion in a disinfectant solution. The disinfectant solution is used by diluting, for example, chlorine-based NaDCC (Sodium Di ChloroIsoCyanurate, sodium isonianulate). At this time, it is preferable to close the cultivation cavity 11-18. The disinfection step is maintained for approximately 10 hours, but when 10 hours have elapsed, the door of the entrance is opened and the ventilation fan 60 is operated to ventilate the cultivation building 11-18. In addition, the cultivation tray 21 from which sprouted vegetables are removed is washed and disinfected in the washing station 34, and then dried and then reused (S8).

In the present invention, the above embodiment is an example, and the present invention is not limited thereto. Anything that has substantially the same configuration as the technical idea described in the claims of the present invention and achieves the same operation and effect is included in the technical scope of the present invention.
