Description

Bean sprouts cultivation apparatus using ultrasonic sprayer

The present invention relates to a soybean sprout cultivator capable of quickly cultivating pollution-free bean sprouts by ultrasonic spray hardening (Ultrasonic aeroponics), thousands of times less water than conventional bean sprout cultivators.

Nowadays, bean sprouts production facilities use most traditional methods, which are not only poor working conditions and production facilities, but also limited by location due to the huge amount of water required. Moreover, the water used to lower the temperature inside the bean sprouts and to remove substances secreted from the bean sprouts generates waste water, causing environmental pollution. In addition, recently, more than necessary bioactive substances are used in order to have a rapid production and shape, and a large amount of pesticides are added to prevent fatal corruption during production and distribution, causing social problems.

In order to make up for these drawbacks, water circulating bean sprouts growers have been developed for domestic use, but when water is continuously circulated, the water containing secretions easily decays or becomes turbid, causing other problems for filtration. It is not easily commercialized.

Therefore, the object of the present invention is to solve the fundamental problem from the physiological point of view of cultivating bean sprouts and to drastically reduce the amount of water in order to drastically improve the current cultivation problems and to produce higher quality bean sprouts. It is to provide a new way to solve.

Still another object of the present invention is to solve the problem of corruption by using no pesticides and to provide a high quality, pollution free food production method.

Another object of the present invention is to provide a possibility of imparting functionality to bean sprouts.

This object of the present invention is achieved by feeding water and nutrient solution by ultrasonic spray instead of water using ultrasonic spray mirror system (Ultrasonic aeroponics).

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the ultrasonic atomizing method is a state-of-the-art cultivation method that can solve the problem of dissolved oxygen deficiency required for root respiration which is often generated during flush cultivation or hydroponics cultivation while supplying sufficient moisture necessary for the development of root sprouts and embryos of bean sprouts. This approach not only optimizes the cultivation environment in an enclosed planter, but also uses only a small amount of water, eliminating wastewater problems, circumventing positional limitations in cultivation, and eliminating the need for special designs to circulate water. In addition, the non-cyclic cultivation method has a feature that can be imparted to the bean sprouts even functionality.

First, the ultrasonic spray hard bean sprouts grower 2 of the present invention for implementing as shown in Figures 1 to 2 is a bean sprouts growing cylinder 20 formed a space for growing bean sprouts; An upper cover 10 having a spray outlet 10-1 formed at an upper end thereof; A bottom support 40 having a space for supplying a spray liquid from the bottom to the top; Ultrasonic spray control unit consisting of a conventional ultrasonic vibrator, a timer (60-2), on / off switch (60-1) not shown to supply and control the spray through the spray discharge port (10-1) of the upper end 60; A level sensor 60-3 which detects the quantity of water filled in the upper portion of the ultrasonic spray controller 60 and applies an electrical signal to the ultrasonic spray controller 60; A spray control valve 80 mounted on one side of the spray supply pipe 120 to adjust the supply amount of the spray; The air circulating fan 140 is driven by an air circulation pipe 130 and a motor formed at an upper portion of the air inlet 10-2 so as to supply air to the bean sprout cultivation container 20. It is made up of the included configuration.

The bean sprout cultivation container 20 shown in Figure 2 is a support plate 90 formed with a plurality of micropores 70, and a reticulated disc that enables oxygen and moisture supply to a freshly shaped mesh structure so that bean sprouts cannot escape. 30), the support plate 90 and the reticular disk 30 is made of a cultivation barrel 110 formed in the lower end of the inside / detachable.

The ultrasonic spray control unit 60 is configured to be supplied through the spray supply pipe 130 and the lower portion of the bulb 50 to the top / bottom to make the water molecules of the ultra-fine particles, the water and air to the bean sprout cultivation container (20) The timer 60-2 is mounted to automatically set the supply amount and the supply time, and the water level sensor 60-3 detects the amount of water supplied by the ultrasonic spray control unit 60 and sends an electric signal to the control unit. In addition, by the control unit that detects the temperature of the bean sprout cultivation container 20 of the bean sprout cultivator 2 in a conventional manner, the operation and stop of the ultrasonic spray control unit 60 and the circulation of the air is performed ( 140) is installed.

On the other hand, the low-speed circulation system using the air circulation fan 140 can supply an appropriate amount of oxygen to the beans in the deep portion by inhibiting the infection of microorganisms by suppressing excessive heat generation in the bean sprout cultivation container 20 and circulating the air at low speed To be.

The traditional method is seasonal, but watering four to six times a day is a common method of cultivation. To date, the known reasons for irrigation include reducing the enormous heat generated by breathing in soybeans, It is intended to wash water because the substances secreted during germination give the invasion opportunity of rot bacteria.

However, in addition to this, there is a bigger reason to maintain normal breathing by bringing fresh air outside to the depths of the beans by washing with water. In addition, most of the heat generated during the cultivation is in addition to the natural heat generated from the original. When the beans are stacked in several layers, the carbon dioxide is accumulated due to lack of air circulation in the beans, which is the heat generated by not only normal breathing but also fermentation. Therefore, the use of low speed circulation system only lowers the temperature. In addition, the normal inhalation of the beans induces a strong growth of germination and hypocotyl.

Detailed view of the present invention is designed on the basis of the commonly used bean sprouts growing cylinder 20, bean sprouts growing container 20 is to be inserted into the planter after the appropriately put the beans in a removable manner and to be removed after planting. The control unit 60 is generated from an ultrasonic generator, not shown, and the particles of the spray used for cultivating bean sprouts are about 3 μm or less. The ultrasonic spray control unit 60 is located at the bottom of the planting machine and the time of the timer 60-2 is maintained. By adjusting the interval, the control valve 80 is switched so that the ultrasonic spray is sprayed into the cultivation barrel by staggering the time through the lower sprayer 50 or the upper sprayer 10-1, wherein the spraying time and the spraying interval are timers ( 60-2) can be adjusted automatically.

On the other hand, the air circulation fan 140 may be installed in such a way that the air is sucked in from the top, the air is pushed in from the bottom.

In addition, while the air inlet 10-2 is formed in the upper cover 10 (see FIG. 1), the forced circulation of air is made through the second air circulation fan 140-1 in the lower support 40. When the air circulation is made by the air circulation fan 140 and the second air circulation fan 140-1, it is also sprayed through the lower spray port 50, and the spray is reduced by pressure or pressure at the same time as the air circulation. Operation of the second air circulation fan 140-1 is performed by the motor 150 driven by the controller of the ultrasonic spray control unit 60. Meanwhile, FIG. 3 is a view of the bean sprout cultivation container 20. As a detailed view, the support plate 90 having the small micropores 70 having a detachable 1 to 2 cm and the oxygen supply and moisture supply plate 30 having a hole of 1.5 mm between the mesh and the 30 to 35 cm in diameter to prevent bean sprouts from falling out. It is comprised by the cultivation container 110 about 34-40 cm.

The support plate 90 may be made of plastic or stainless plate, and the mesh disc 30 capable of supplying oxygen and moisture in the shape of a mesh structure may be made of stainless steel or plastic net.

The net is formed in a cylindrical structure with a perforated diameter of 3 to 5 cm and a height of 5 to 7 cm made of the same material, especially in the middle portion.

Meanwhile, the water used in the present invention uses acetic acid water, and acidic water and alkaline water are generated when the water is electrolyzed and double acidic water is used. In general, electrolytic acidic water has an acidity (pH) of 4 to 4.5 and has little sterilizing power.However, when acidified by adding NaCl or KCl in water, it is produced as acetic acid and alkaline water. Has a pH of 2.7, EC 1 mA / cm and a redox potential of about 1,100 mA.

Acetic acid water has a strong bactericidal effect due to chlorine substance, low acidity (pH), and redox potential difference of 1,100㎷, which can prevent the decay during soybean germination, cultivation and distribution.

On the other hand, alkaline water has a growth promoting effect, when using alternating acidic water and alkaline water at regular intervals when cultivation can be obtained at the same time to prevent corruption and growth promoting effect.

In particular, conventional cultivation of the conventional method is because it uses and discards the water once, so it is not worth considering economically to make functional bean sprouts by adding substances necessary for the human body to the water, but in the case of the present invention using only a small amount of water, hydroponic cultivation In the same way as to put a variety of substances beneficial to humans can be grown sprouts suggests the possibility of functional sprouts.
