Abstract

PURPOSE:To obtain a delicious bean sprout giving good feeling to the tooth and having high preservability, by growing seeds on a holding base, shooting roots through a number of root-shooting holes and cutting the roots extended downward or the leaves protruded above the holding base. CONSTITUTION:A net 12 having a mesh opening 120 of a size to prevent the drop of a mung bean used as a material for bean sprout is stretched at the bottom of a rectangular frame 11 attached to a shelf frame 1. Mung beans are scattered on the net 12 preventing the overlapping of the beans and sprayed with water of a proper temperature to effect the germination. The stalk 31 grows straightly upward and the root 32 grows downward through the mesh 20 of the net 2 to form a bean sprout 3 of mung bean. When the stalk 31 of the bean sprout 3 is grown to a length suitable to be marketed, the shelf frame 1 is put into a guide 4 and transferred toward a disk cutter 5 positioned at a level slightly lower than the shelf 12. The root 32 of the bean sprout 3 is cut by this process. The root 32 which is a principal factor to lower the quality and commercial value of bean sprout 3 can be removed in high efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing rootless bean sprouts.

[Prior art and its problems] Bean sprouts, which are vegetables whose seeds are soaked in water and germinated, are generally grown as follows.

First, seeds such as black beans, mung beans, or soybeans (hereinafter referred to as "seeds") are soaked in hot water at a temperature of 45℃ to 60℃ for 4 to 5 hours.The water is drained, and after about 3 hours, growth is stopped and the stems are thickened. For this purpose, move the plants to a separate room and water them with water at a temperature of 23°C 4 to 5 times a day.

In this way, the seeds grow into sprouts in about 78 and a half days in winter and about 4 to 5 days in summer.

Bean sprouts grown in this way are packaged and shipped with their roots still attached, but the roots are hard and have a bad texture, making them unpalatable to eat as is. For this reason, it is necessary to remove it when cooking, but this work is time-consuming and troublesome.

Also, should bean sprouts be transported or purchased with the roots included?
The root portion accounts for a large proportion (more than 30% by weight),
They are forced to incur extra expenses for transportation and purchase.

Furthermore, the roots quickly turn black, making them unsightly and disadvantageous for sale.

There are other problems.

[Objective of the present invention] The present invention provides rootless bean sprouts that are delicious and have high commercial value by efficiently removing the root portion, which is a major factor in the decline in quality and commercial value of bean sprouts.

[Configuration of the present invention] The configuration of the present invention taken to solve the above problems and achieve the objectives is as follows.

That is, in the present invention, seeds are grown on a mounting body having a large number of rooting holes formed in a size that prevents the seeds from falling, roots are made to come out from the rooting holes, and after growing, roots are grown downward from the rooting holes. This is a method for producing rootless bean sprouts in which the roots that are present or the stems that are growing on a mounting body are cut.

In the present invention, the mounting body has a large number of rooting holes so that the roots of the bean sprouts can penetrate through the rooting holes and extend, and for example, a net, a punching board, a metal lath, etc. are used. , its structure is not particularly limited.

According to this mounting body, a large number of shelves can be provided in the horizontal and vertical directions to effectively utilize the space.

It is preferable to sow seeds on the mounting body so that they do not overlap each other as much as possible.

The seeds are watered and germinated, and when the stem portion grows to a predetermined length, the roots extending downward from the rooting hole or the stems extending upward from the mounting body are cut with a cutter.

When cutting the stem, it is best to cut the part closest to the roots so that the part that the bean sprouts will eat is not wasted.

Cutting roots or stems with a cutter is usually performed by moving a shelf-shaped mounting body to a fixed disc cutter, but the method is not limited to this method.

[Example] FIG. 1 is an explanatory diagram of an embodiment of the present invention.

The shelf frame 1 includes a rectangular frame body 11, and a net body 12 having a mesh size 120 large enough to prevent mung beans, which are the material for bean sprouts, from falling is stretched over the bottom of the frame body 11.

Mung beans are sown on this net 12 so as not to overlap with each other, and water at an appropriate temperature is sprinkled to cause them to germinate.

In this case, since there is no obstacle in the upward direction, the stem 31 extends straight upward, and the phallus 32 penetrates the mesh 20 of the net body 2 and extends downward. In this way, mung beans become bean sprouts 3.

When the stems 31 of the bean sprouts 3 have grown to a suitable length for commercial use, the shelf frame 1 is fitted into the guide 4 and moved towards the disc cutter 5 located at a height slightly below the rope body 12 of the shelf frame 1. let As a result, the roots 32 of the bean sprouts 3 are cut.

[Effects of the Invention] According to the present invention, seeds are grown on a mounting body having a large number of rooting holes formed in a size that prevents seeds from falling, roots are made to come out from the rooting holes, and roots are grown after growing. Since the roots extending downward from the holes or the stems extending above the mounting body are cut, the roots, which are a major factor in the decline in the quality and commercial value of bean sprouts, can be efficiently removed, resulting in a good texture. It is possible to provide bean sprouts that are delicious and have a long shelf life.
