Abstract

PURPOSE:To simply obtain a large amount of bean sprouts having good taste and soft fibers free from variability of qualities by seeding a fixed amount of seed beans in a specific culture container, growing and cutting roots. CONSTITUTION:Seed beans 4 are seeded in a culture container 1 which has such a great number of holes 7 as to pass through roots 6 of bean sprouts 5 on the bottom 2 and wall faces having height corresponding to height of grown bean sprouts at the periphery in such a density that the bean sprouts can thickly grow on the bottom 2 when seed beans 4 are grown. The culture containers 1 are piled in plural stages and the bean sprouts are grown while maintaining proper temperature and amount of water sprinkled and isolating light rays. Then the culture containers 1 are successively taken out, the roots 6 are cut off by a cutter to give root cut bean sprouts free from variance of qualities.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing bean sprouts, and particularly to the production of root-cut bean sprouts with consistent quality.

[Conventional technology]

Traditionally, the method of producing bean sprouts was to sow seed beans in multiple stages in a cultivation container and grow them under certain conditions. Since the directions vary, it was impossible to cut out the roots and commercialize them from a cost perspective.

Therefore, as a method for producing root-cut bean sprouts, multiple shelves are set up, seed beans are sown in several tiers on a mesh board, and the seeds are grown under certain conditions and the roots are removed. or(
Conventional Example 1) and a method (Conventional Example 2) in which seed beans and water-permeable partition walls are alternately laminated in a cultivation container are sometimes adopted.

[Problem to be solved by the invention]

However, if there is too much air circulation during growing bean sprouts, the fibers will become stiff and the taste will deteriorate. Air freely enters and exits from the sides, making it impossible to produce bean sprouts with good taste. Seed beans generate heat as they germinate and grow, but if the area around the shelf is open, there will be a temperature difference between the inside and the surrounding area, which will result in differences in the growth of the bean sprouts, making it impossible to produce uniform bean sprouts. There was also the problem.

On the other hand, in Conventional Example 2, air can be appropriately blocked, but since the growth density of the bean sprouts on each partition wall is small, the bean sprouts below cannot fully resist gravity and the growth rate is suppressed. Differences occur between the upper bean sprouts and the lower bean sprouts, making it impossible to produce uniform bean sprouts.

The object of the present invention is to solve these problems and to mass-produce root-cut bean sprouts with good taste and uniform quality.

[Means to solve the problem]

In order to achieve the above object, the present invention has a bottom surface with a large number of holes through which the roots of the bean sprouts can penetrate, and a surrounding wall surface with a height corresponding to the height at which the bean sprouts have grown. A method was used in which the seeds were sown at a density that allowed them to grow densely on the bottom surface, the cultivation containers were stacked in multiple layers, and then the bean sprouts were grown in an atmosphere for growing bean sprouts, and the roots of the bean sprouts were cut along the bottom surface of the culture container described above. .

[For production]

The cultivation container has many holes on the bottom, and as the sprout grows, the roots penetrate through the holes and the sprout grows vertically.
Since the wall surface corresponds to the height at which the bean sprouts are grown, the bean sprouts can be grown straight without any obstacles.

In addition, the surrounding wall surface prevents too much air from passing through the bean sprouts, allowing an appropriate amount of air to flow from above and below the multi-layered cultivation containers.

After the bean sprouts have grown to a desired height, the roots are cut along the bottom of the culture container to produce root-cut bean sprouts.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.
The figure shows the cultivation containers stacked after sowing seeds, Figure 2 is a schematic diagram showing the bean sprouts grown to the desired height, Figure 3 is a perspective view of the cultivation containers, and 1 is the cultivation container, 2
3 is the bottom surface of the cultivation container 1, 3 is the wall surface of the cultivation container 1, 4 is stirring, 5 is the grown bean sprout, and 6 is its root. The bottom surface 2 is provided with a large number of holes 7 large enough for the roots 6 of the bean sprouts to pass through, and as the sprouts grow, the roots 6 extend downward through the holes 7, and the bean sprouts 5 extend upward. The wall surface 3 is made of a light-shielding material so as not to allow light to pass through.

The order of production is as follows: First, when the stirring 4 is grown in each of a plurality of cultivation containers 1...l, the seeds are sown at a density that allows the bean sprouts to grow densely on the bottom surface 2 (usually about 1.5 to 2 stages). Stack them in about 20 layers. After this, grow for about 8 to 10 days while ensuring an appropriate temperature and watering amount, blocking light, and when it grows to about 5 to 8 cffI as shown in Figure 2, take out the cultivation containers one by one and cut the roots 6. The bean sprouts are produced by removing the roots.

It should be noted that bean sprouts can produce products with thick stems and crispness by applying an appropriate amount of gravity, so a water-permeable sheet of an appropriate weight may be placed over the bean sprouts after sowing the seeds.

In the above configuration, if the bottom surface 2 of the cultivation container 1 is made too thick, a considerable length will remain even if the roots 6 are removed, so it is preferable to keep the bottom surface 2 to about 1 to 411 mm. Further, since the length and thickness of ordinary bean sprouts and soybean sprouts are different, the height of wall surface 3 and the size of hole 7 need to be set appropriately depending on the type of bean sprouts.

That is, the wall surface 3 is set at a height such that the heads of the bean sprouts cannot touch the bottom of the upper tier during cultivation, and the holes 7 are set at a diameter so large that the bean sprout stems cannot penetrate into the holes 7. do.

It should be noted that the configuration of the holes 7 may be of any shape, such as a net shape, a screen shape, etc., as long as there are a large number of holes in the bottom surface 2.

Furthermore, the cultivation container 1 and the bottom surface 2 may be integrally molded from synthetic resin or the like, or may be constructed separately.

As for how to use the cultivation container 1, the opening side may face upward as shown in Fig. 1, but it is also possible to sow the seeds on the back side of the bottom 2 with the opening side facing downward. It is possible to achieve the production effect of

〔Effect of the invention〕

Since the present invention has the above configuration, bean sprouts can be grown densely in each cultivation container, and root-cut bean sprouts can be easily produced by simply cutting out the roots after growing.

In addition, by stacking the cultivation containers, the walls can appropriately block air, making it possible to produce bean sprouts with soft fibers.The walls also have a heat-retaining effect, so that the surroundings and center of the bean sprouts can be separated. Temperature differences can be suppressed and variations in growth are less likely to occur.

Furthermore, since each cultivation container is isolated, the gravity applied to the bean sprouts in the upper and lower rows is uniform, so there is no variation in the growth of the bean sprouts in each cultivation container, and other effects that could not be expected with conventional methods. can be played.
