Description

  The present invention relates to a hygienic cultivation method for sprout, and supports silver ions, which are known to have antibacterial and antiviral properties, on a cultivation bed, and sown sprout seeds in a form that is wrapped in the cultivation bed. A sprout for household use that sprinkles water containing silver ions with temperature control, germinates and grows it, and cultivates it so that the amount and interval of watering can be set arbitrarily, so that it can be easily harvested. It is related with the cultivation apparatus.

  Traditionally, sprout is well known as a health food because it has a high nutritional value and can be ingested in small quantities, and has attracted more and more attention in recent years.

  In conventional cultivation equipment, the seed sowing medium is a mesh-like perforated resin plate tray, or a slotted perforated resin plate tray. It was something to do.

  Therefore, the roots rooted from the seeds enter the mesh of the tray made of perforated resin plate and get entangled, the roots are not easily pulled out, and the roots are cut and harvested at the lower end of the stem part, but in the next cultivation, The previous roots that were tangled in the mesh of the perforated resin tray must be peeled off, cleaned, washed, and reused, which is very laborious.

  Sprout is an ingredient that is often eaten raw, so there is a risk that it will rarely become a cause of food poisoning, and hygiene management and prevention of bacterial growth are very important factors in cultivation. It has become to.

JP 2006-262844 A In addition, there is a patent application filed on 2011/10/23 as prior art documents of the present applicant.

However, in the above-mentioned conventional technology, at the time of harvesting, many components of the cultivation apparatus must be removed and the cultivation tray must be taken out.
When the sprout stalks are cut from the cultivation tray, removed, transferred, and washed, the cultivation tray has a large area, so it cannot be treated with a single bite and can be cut and harvested in several degrees, or the entire surface must be cut at once. In this case, the sprout stalks are separated and removed in several degrees, and the sprout stalks are in a separate collection state, and it is impossible to harvest the sprout stalks in a beautifully aligned state.
When the next cultivation is continued after the previous harvest, it takes much time and effort to remove and clean the root of the cultivation tray.

  Since there is no hygienic measure for cultivation water, there is a risk that it will become a source of odor if the cultivation water is not changed every day. there were.

  Since there is no function to adjust the amount of sprinkling according to the type of sprout seeds, there is a problem of root rot due to excessive moisture and lack of moisture depending on the seeds.

There are many types of sprout, and the optimal temperature for germination of general sprout seeds is approximately 15 ° C or higher, but it is about 1.9 times that of broccoli, which is said to have a high cancer prevention effect. Knowing that the growth environment temperature is about 8 ° C to 15 ° C, it is necessary to control the temperature to an appropriate temperature according to the type of sprout. Therefore, a function capable of controlling the optimum cultivation temperature according to the sprout species is desired.
The present invention has been made to solve the above drawbacks.
