Shower type, 2. Spray type, 3. There are three methods of flooding, shower and spray are ideal for large-scale production of sprouts under the principle of natural farming, that is, without adding any chemical agents, artificial ethylene, nitrogen, antibiotics or fertilizer. Instead, when cultivated in a flooded manner, sprouts of relatively stable quality can be obtained. However, generally, flooded cultivation boxes have the disadvantage of relatively large water consumption,
In addition, when stacked in a multi-layer type, it is difficult to control the water supply amount and water supply time with a single water supply device, and the water temperature rises when the water that has passed through the upper box body flows to the lower box body. There was a discrepancy between the quality of the sprouts cultivated in the lower box and the lower box.

In growing bean sprouts, depending on the type of beans, the amount of water required in each of the soaking process (soaking the seeds in water), germination (promotion of germination), and germination (growing of sprouts) during the cultivation process is determined. Due to the different water supply intervals, in order to complete the above three processes in the same container, that is, without changing the cultivation environment, a new sprouts cultivation method and the design of an automatic water supply and drainage system are necessary. At the same time, save time, labor and water,
It must be able to shorten the cultivation time, three-dimensional,
Cultivation using an automated farm system can reduce production costs and improve competitiveness in the market.

[0027]

The present invention is an apparatus for cultivating bean sprouts by a flooded method, in which a plug 43 for circumscribing the water supply / drainage port is provided outside the box body of the cultivation box 4, and the arrangement method shown in FIG. 8 or another arrangement method is adopted. After that, the programmed electronic controller accurately controls the flow velocity controller, solenoid valve or other related control parts provided at the front and rear ends of the water supply pipe,
Water supply and drainage of the cultivation box 4, water level and water supply and drainage interval time are controlled, and thus one of the features is that various types of bean sprouts can be cultivated fully automatically according to the season, the temperature, and the type of beans. When water is supplied to the cultivation boxes 4 on the same layer surface, the water supply / drain connector 74 and the water supply branch pipe 732 are communicated with each other so that the water volume in each cultivation box 4 is quickly and automatically brought into an equilibrium state. (The bean sprouts can uniformly absorb and radiate water).

In Japan, chemical agents are used in the production of bean sprouts,
For example, the addition of fungicides, growth hormones and the like is prohibited, and artificial ethylene gas and nitrogen gas are slightly added during the sprouts cultivation process, and the room temperature is controlled. During the entire cultivation process, the time from sowing to harvest takes 7 to 8 days in summer and 10 to 12 days in winter, so that sprouts are harvested 9 to 10 times the weight of the beans. And 30% of bean sprouts are stunted or bacterially infected, and the harvest begins to spoil after storage in a refrigerator for 3-4 days after packaging. From this fact, it can be seen that the artificial ethylene gas has not actually changed to ethylene oxide to generate the sterilizing ability.

The present invention is based on the principle of applying elastic physical pressure to bean sprouts to place ethylene sprouts on the opposite side and generate ethylene gas. That is, the weighed beans are placed on a grid-shaped bean catching board 2 and further combined with an elastic pressure lid 1 through which air and water pass to form a cultivation set.
