Description

Immersion type cultivating device of bean sprouts}

The present invention relates to an immersion cultivation device, and more specifically, to a device for immersion cultivation of legumes that grow through respiration, such as bean sprouts and bean sprouts.

Legume sprouts, such as bean sprouts and bean sprouts, are grown by germinating soybeans, mung beans, etc. and growing them through respiration. For example, bean sprouts are grown by sprouting mung beans, which are the raw material, and are a widely consumed food ingredient not only in Korea but also around the world for stir-frying and salads. For the growth of legumes, groundwater is used as per Domestic Patent Publication No. 2020-0046977. Taking bean sprouts as an example, soaked mung beans are placed in a cultivation container, and ground water, which is usually at a temperature of approximately 20℃ to 24℃, is supplied by a watering device at intervals of 4 hours, 4 to 6 times a day, during the cultivation period of about 7 to 8 days. while supplying groundwater. The groundwater supplies the moisture necessary for the growth of legumes, maintains the temperature between legumes, washes organic matter secreted from legumes, removes respiratory gases such as carbon dioxide generated during the growth process, etc. performs the role of

Meanwhile, legumes use a huge amount of groundwater as cultivation water during the cultivation process. Typically, more than 140 liters of groundwater is used to produce one 3.5 kg box of bean sprouts. If a large amount of groundwater is used, the groundwater around the cultivation area becomes depleted after a certain period of time. When groundwater is depleted, cultivation areas must be moved and become the subject of complaints from residents. In this way, even though cultivation water equivalent to approximately 40 times or more than dozens of times the amount of legumes produced is used, the above role is not sufficiently performed, and rotting of legumes in specific areas sometimes occurs. In addition, since groundwater is heated and used, a lot of energy costs are required.

The problem that the present invention aims to solve is to reduce the amount of groundwater used, maintain an appropriate temperature between legumes, wash organic matter secreted from legumes, and remove respiratory gases such as carbon dioxide generated during the growth process. The purpose is to provide a legume sprout immersion cultivation device that sufficiently performs the following roles.

The legume sprout submersion cultivation device for solving the problem of the present invention includes a water tank that converts groundwater inflow into cultivation water, a cultivation container with a growth area in which legume sprouts are immersed and grown in the cultivation water, and It includes a water supply pipe disposed between the water tank and the cultivation container to supply the cultivation water to the cultivation container. At this time, in the cultivation container, a drain valve and a bottom exhaust portion are attached to the bottom of the storage tank in which the cultivation water is stored, and the bottom exhaust portion includes an exhaust valve connected to the bottom of the cultivation container and an exhaust fan in communication with the exhaust valve. do.

In the device of the present invention, the water tank includes a water tank water level sensor for controlling the amount of inflow water by measuring the water level of the inflow water, a heater for heating the inflow water, and a temperature sensor for measuring the temperature of the cultivation water. The water tank may include a circulation pump that circulates the cultivation water. The cultivation container may include a container water level sensor for controlling the amount of cultivation water by measuring the water level of the cultivation water and a temperature sensor for measuring the temperature of the growth area.

In the device of the present invention, the drain valve and the exhaust valve are closed during the immersion time during which the legume sprouts are immersed in the cultivation container, and when the immersion time has elapsed, the drain valve is opened to open the growth area and the storage tank. The replanting water of can be removed. In order to control the temperature of the growth area during the immersion time, the cultivation water may be additionally supplied from the water supply pipe. When the cultivation water is removed, the drain valve is closed and the exhaust valve is opened to discharge the breathing gas generated from the respiration of the legume sprouts. When the cultivation water and the breathing gas are removed, the drain valve and the exhaust valve are closed to allow the legume sprouts to grow.

In a preferred device of the present invention, the cultivation vessel may include a vibrator attached to at least one of the inner surface, the outer surface, or both sides. The vibrator is operated while the legume sprouts are immersed, and optionally, the drain valve is closed and the exhaust valve is opened to discharge breathing gas generated from the respiration of the legume sprouts. A micro bubbler may be included between the water tank and the water supply pipe. The microbubble device may be operated with a vibrator attached to at least one of the inner surface, outer surface, or both sides of the cultivation vessel.

According to the legume sprout submerged cultivation device of the present invention, submerged cultivation is performed using the bottom exhaust part, thereby reducing the amount of groundwater used, maintaining the temperature between legume sprouts, washing organic substances secreted from legume sprouts, and growing. It sufficiently performs the role of removing respiratory gases such as carbon dioxide generated during the process.

Figure 2 is a diagram schematically explaining the second cultivation device according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. The embodiments described below may be modified into various other forms, and the scope of the present invention is not limited to the embodiments described in detail below. Examples of the present invention are provided to more completely explain the present invention to those skilled in the art. In the drawing, the representation is exaggerated for convenience of explanation. Meanwhile, terms indicating location, such as top, bottom, front, etc., are only related to what is shown in the drawing. In practice, the cultivation device can be used in any optional orientation, and in actual use, the spatial orientation changes depending on the orientation and rotation of the cultivation device.

An embodiment of the present invention performs submerged cultivation using a bottom exhaust part, thereby reducing the amount of groundwater used, maintaining the temperature between legumes and sprouts, washing organic matter secreted from legumes and sprouts, and removing carbon dioxide and carbon dioxide generated during the growth process. We present an immersion cultivation device that sufficiently performs the role of removing breathing gases. To this end, we will look at the submerged cultivation device equipped with a bottom exhaust part in detail, and explain in detail the effect that the bottom exhaust part has on submerged cultivation. Legume sprouts include bean sprouts and bean sprouts, which germinate soybeans, mung beans, etc. and grow through respiration. Here, bean sprouts will be used as an example.

Figure 1 is a diagram schematically explaining a first cultivation device 100 according to an embodiment of the present invention. However, it is not a drawing in the strict sense, and there may be components not shown in the drawing for convenience of explanation.

According to Figure 1, the first cultivation device 100 includes a water tank 10 and a cultivation container 20. Inflow water, such as groundwater, flows into the water tank 10 through the inlet valve 11. The amount of water flowing into the water tank 10 is limited by the water tank water level sensor 12. The water tank water level sensor 12 is a type of flow sensor and serves to control the amount of inflow water by measuring the water level of the inflow water in the water tank 10. The inlet valve 11 can be mechanical, and in some cases, an electronic type such as a solenoid valve can also be applied. The influent water flowing into the water tank 10 is heated to an appropriate temperature by the heater 13 and becomes re-watering water. The temperature of the heated cultivation water is measured by the temperature sensor 14, and the cultivation water is preferably circulated by the circulation pump 15 to achieve a uniform temperature.

In the case of bean sprouts, the appropriate temperature for the cultivation water is approximately 20°C to 24°C. If the temperature of the cultivation water exceeds the appropriate temperature, germs such as bacteria multiply rapidly and rot the host greens. On the other hand, the cultivation water can be mixed with sugar, fruit juice, red ginseng liquid, and desired herbal medicine additives at a certain ratio to improve the nutritional content of bean sprouts (BS) or add a desired flavor. Additionally, legume sprouts (BS) contain isoflavones. The isoflavone exhibits a similar structure and activity to estrogen, a flavonoid female hormone, and is also called a phytoestrogen. Isoflavones are composed of genistein, daidzein, glycitein, and glycosides. Isoflavones are known to be effective in preventing not only breast cancer but also prostate cancer, colon cancer, cardiovascular disease, osteoporosis, and menopausal syndrome. The cultivation water may contain abscisic acid (ABA), which can increase the isoflavone content.

The cultivation water in the water tank 10 is supplied to the cultivation container 20 through the water supply pipe 17 using the water pump 16. The amount of cultivation water supplied to the cultivation container 20 is limited by the container water level sensor 21. The container water level sensor 21 is a type of flow sensor and serves to control the amount of cultivation water by measuring the water level of the cultivation water in the cultivation container 20. The cultivation container 20 includes an inner surface 20a and an outer surface 20b, and includes a tray 22 and a storage tank 24 on which legume sprouts (BS) are placed. There is a growth area (A) where legume sprouts (BS) grow between the tray 22 and the cultivation surface (a). The size of the growth area (A) varies depending on the growth rate of legume sprouts (BS). The container water level sensor 21 measures the water level of the cultivation water and controls the amount of cultivation water so that the growth area (A) and the cultivation water level (a) match. There are a plurality of dripping holes 23 in the tray 22, so that the cultivation water supplied to the growth area A passes through the dripping holes 23 and is stored in the storage tank 24.

The process of cultivating legume sprouts (BS) includes a soaking process, drainage process, exhaust process, and growth process. The immersion process is a state in which the growth area (A) is immersed in cultivation water during the immersion time, and the drainage process is a process of removing the cultivation water from the growth area (A) and the storage tank 24. The exhaust process is a state in which the breathing gas of the growth area (A) is exhausted, and the growth process is a process in which the drainage and exhaust processes are completed and the legume sprouts (BS) grow on their own. The respiratory gas is a gas such as carbon dioxide that is generated when legume sprouts (BS) grow through respiration. The soaking process, drainage process, exhaust process, and growth process are one cycle, and multiple cycles are repeated in the process of cultivating legume sprouts (BS).

In the immersion process, the immersion time can be set variously depending on the type of legume sprouts (BS), the growth rate of legume sprouts (BS), the temperature of the cultivation water, etc. In the case of bean sprouts, it is about 5 to 15 minutes. am. When soaked for a certain period of time and waiting for a certain period of time, legume sprouts (BS) decompose stored nutrients stored in the beans and move to the growth point to create new cells. Afterwards, as cells proliferate actively, soybean buds grow and small roots grow, allowing harvesting after a few days. During the soaking time, the drain valve 30 and exhaust valve 34 are closed.

In the immersion process, putrefactive bacteria proliferate by ingesting organic matter secreted by the legume sprouts (BS) during the growth process, and the temperature rises due to the respiratory heat of the legume sprouts (BS). As temperatures rise, spoilage bacteria multiply rapidly around legume sprouts (BS), producing strong toxins and enzymes. The toxins and enzymes are absorbed into the legume sprouts (BS), causing the legume sprouts (BS) to rot. The temperature sensor 25 is inserted into the growth area (A) of the legume sprouts (BS) and measures the temperature around the legume sprouts (BS). If the temperature around the legume sprouts (BS) is higher than the appropriate temperature, cultivation water is supplied from the water supply pipe 17 to maintain the temperature around the legume sprouts (BS) at an appropriate temperature. If necessary, in the process of supplying cultivation water from the water supply pipe 17, the water level in the growth area A can be maintained by temporarily opening the drain valve 30 and operating the drain pump 31.

The draining process is performed after the immersion process is completed. Specifically, the drain valve 30 is opened and the drain pump 31 is operated to remove cultivation water from the growth area A and the storage tank 24. At this time, the exhaust valve 34 is in a closed state. Preferably, the drain pump 31 can send the cultivation water to the water tank 10 through the drain pipe 32. However, since the cultivation water contains various bacteria and foreign substances, the purifier 33 can be placed between the drain pump 31 and the water tank 10 to sterilize and remove foreign substances. For example, the sterilization is not necessarily limited to this, but known heat, ultraviolet rays, ozone, electrolyzed water, etc. may be used. It is recommended to use a filter to remove the foreign substances.

The exhaust process is performed after the drainage process is completed. Specifically, the exhaust valve 34 is opened and the exhaust fan 35 is operated to remove breathing gas from the growth area (A). At this time, the drain valve 30 is closed. Meanwhile, when legume sprouts (BS) grow, the head of the legume sprouts (BS) is preferably located on the other side of the exhaust valve 34. Since the head part has a high density, it is relatively easy to discharge respiratory gas from the root. The exhaust valve 34 and the exhaust fan 35 are disposed on the bottom 20c of the cultivation container to allow the breathing gas to be discharged from the root side. This exhaust valve 34 and exhaust fan 35 are called the bottom exhaust portion (B). Meanwhile, the growth process is a process that allows legume sprouts (BS) to grow naturally without the cultivation water and the breathing gas. At this time, it is preferable that the drain valve 30 and the exhaust valve 34 are closed.

Optionally, the vibrator 26 may be disposed on the inner surface 20a or the outer surface 20b or on both sides of the cultivation vessel. The vibrator 26 can be any type that induces vibration in the growth area A, such as an ultrasonic generator or an eccentric vibration motor. When the vibrator 26 is applied, during the immersion process, the cultivation water flows so as to be distributed throughout the growth area A. Additionally, in the immersion process, if the cultivation water is uniformly distributed, the temperature sensor 25 can accurately measure the cultivation water temperature throughout the growth area (A). In other words, if the cultivation water is uniformly distributed, by measuring the cultivation temperature in a part of the growth area (A), the cultivation temperature in the entire growth area (A) can be inferred.

Applying the vibrator 26 prevents the deposition of respiratory gas in the legume sprouts (BS) during the immersion process. It helps the breathing gas to dissolve in the cultivation water. Applying the vibrator 26 induces the breathing gas from the legume sprouts (BS) to be easily discharged during the exhaust process. Specifically, the vibration of the vibrator 26 allows breathing gas that has penetrated between the legume sprouts (BS) to be easily discharged. The vibrator 26 is preferably operated during the immersion process and the exhaust process, but in some cases, it may also be operated during the growth process.

In the case of bean sprouts, the immersion time during the immersion process is approximately 5 to 15 minutes, and the growth process is approximately 2 to 5 hours. Submerged cultivation of the present invention can significantly reduce the amount of inflow water, which is groundwater, consumed compared to sprinkling cultivation. In other words, sprinkling cultivation requires continuous irrigation of groundwater, but immersion cultivation requires cultivation water during the immersion time, so groundwater can be greatly reduced. In the submerged cultivation, legume sprouts (BS) are immersed in cultivation water, so the temperature of the cultivation water is maintained evenly throughout the growth area (A), thereby preventing partial rot. In addition, since the legume sprouts (BS) are immersed in cultivation water, organic matter, which is food for bacteria, is efficiently removed, and the freshness of the legume sprouts (BS) can be maintained for a relatively long time.

Figure 2 is a diagram schematically explaining the second cultivation device 200 according to an embodiment of the present invention. At this time, the second cultivation device 200 is the same as the first cultivation device 100 except that it further includes a microbubble device 40. Accordingly, detailed description of overlapping parts will be omitted.

According to Figure 2, the micro bubble machine 40 is preferably disposed between the water tank 10 and the water supply pipe 17, preferably between the water pump 16 and the water supply pipe 17. Micro bubbles are ultrafine bubbles that are approximately 5㎛ or less in size and cannot be seen with the naked eye. The surface of each of the microbubbles is negatively charged, and the negatively charged microbubbles absorb organic matter generated from the BS and allow the BS to be washed. Meanwhile, when the micro bubbles are destroyed, they act on the surrounding air to generate negative ions with a weak negative electric current. Since the anion has antibacterial activity, it inhibits the growth of bacteria and delays the spoilage of legume sprouts (BS).

Additionally, when the microbubbles are destroyed, oxygen contained in the bubbles is supplied to the legume sprouts (BS). When oxygen is supplied, the growth of legume sprouts (BS), which breathe with oxygen, accelerates. The vibrator 26 activates the flow of the microbubbles and increases the penetration power of the microbubbles between legume sprouts (BS). Accordingly, when the micro bubble machine 40 is operated together with the vibrator 26, the effect of the micro bubbles can be further increased.

Above, the present invention has been described in detail with preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications can be made by those skilled in the art within the scope of the technical idea of the present invention. possible.
