PURPOSE:To automatically grow a small amount of bean sprouts in high efficiency, by feeding seeds of bean sprouts in a growing chamber with the water of appropriate temperature in a water feed tank automatically and intermittently. CONSTITUTION:The bottom of a growing chamber 2 fitted with an openable cover 3 is provided with plural small holes 2a, a porous material 6 being laid thereon, and seeds of bean sprouts are scattered on said material 6. Thence, the chamber 2 is placed on a water feed tank 4, and the water in said tank 4 is kept at appropriate temperatures through an alternate current source 15, an on-off switch 16, a controller 13, a temperature detector 14 and a heater 12, and introduced via a piping 9, into an air pump 7 followed by incorporating the water with bubbles and then feeding the resultant bubble-contg. water via a feed pipe 8 into the spray nozzle 5a of a rotary sprinkler 5 to carry out sprinkling on the beam sprouts. Along with this process, a pump 7 is intermittently operated through a controller 10 and a timer 11 to circulate the water through the small holes 2a and the tank 4. |
