Description

Bean sprout production through irrigation water recycling using ozone to eliminate agricultural chemicals}

The present invention relates to a method of cultivating groundwater-saving pesticide-free sprouts using ozone sterilizing water recycling, and more specifically, to apply the conventional method of producing bean sprouts, which is a traditional Korean food, to mass production, and to exclude pesticides from food. The present invention relates to a method of cultivating groundwater-saving pesticide-free sprouts using ozone sterilizing water recycling to increase safety and save groundwater.

Traditional bean sprout cultivation method is to utilize the various active ingredients released from growing bean sprouts by cultivating again using water used to produce bean sprouts. Since there is an endogenous substance that suppresses the sprouting of soybean sprouts in the active ingredient, it is possible to exclude the use of pesticides (growth regulators, indole ratios) that are currently used to promote the growth of bean sprouts and to suppress the occurrence of soybean sprouts. Distrust of consumers can be solved.In recent years, the method that is cultivated by most growers uses only one growing water and sheds water. In addition, recently, a method for preventing rot caused by sterilization by ozone has been attempted, but these were methods of not reusing water (Patent Nos. 137878 and 234415). On the other hand, Utility Model Registration No. 20 As disclosed in -123375, water reuse is attempted by using ultraviolet germicidal power, but the germicidal effect of ultraviolet lamps is only effective when the temperature of the lamp is 40 ° C or higher, and the turbidity of water must be less than NTU 2.0. Sterilization effect is greatly reduced even if small amount of insoluble solid (500ppm or more), iron (0.03ppm or more) or magnesium (0.05ppm or more) is present in water. In addition, the presence of calcium ions in the water causes impurities in the UV lamp, which reduces the sterilization effect. Usually, when soybean sprouts are cultivated and recycled for about 5 days, turbidity reaches 8 to 10 NTU, and the transmittance of ultraviolet rays is greatly reduced. In addition, in the bean sprouts grower, since the temperature of the water is about 20 ° C. to lower the temperature of the ultraviolet lamp, the sterilization effect is reduced. Therefore, it is difficult to use it in general growers because it is costly to remove impurities and control temperature and it is not effective.However, reuse of cultivated water using ozone sterilization significantly clears turbidity of dissolved water and reduces dissolved oxygen amount. Since it increases more than three times, there is an advantage that it is much easier to grow bean sprouts than ultraviolet sterilization. In addition, the sterilization using ultraviolet rays requires a process of purifying water with a fine filter, but recycling by ozone sterilization can be circulated using only a filter such as a mesh so that the nozzle of the spraying part is not blocked.

An object of the present invention was devised to solve the above problems, there is no residual ingredient, it can increase the dissolved oxygen supply to the sprouts during growth and ozone sterilization water recycling to maintain the sensory quality of traditionally grown bean sprouts It is to provide a groundwater-saving pesticide-free sprouts growing method using the above. Another object of the present invention is to transfer the traditional cultivation method to establish the mass production of bean sprouts, to realize pesticide-free cultivation, to save the groundwater used in the cultivation In addition, the present invention provides a method of growing groundwater-saving pesticide-free bean sprouts using ozone sterilizing water recycling to purify the cultivated water discarded after cultivation of bean sprouts.

In order to achieve the above object, the groundwater-saving pesticide-free sprouts cultivation method using ozone sterilizing water recycling according to the present invention comprises the steps of storing the cultivation water in a storage tank; Sterilizing and purifying the grown water by ozone aeration; Adding a substance selected from chitosan, germanium and elvan to the sterilized and clarified growing water; Watering the cultivated water in a state where a small amount of dissolved ozone remains using a nozzle; Collecting the sprinkled cultivation water through the drip tray and recovering it into a small settling tank; Moving the cultivated water recovered to the small settling tank to the storage tank by a circulation pump; Sterilizing the cultivated water transferred to the storage tank with ozone; And continuously circulating the cultivated water until the cultivation of bean sprouts is completed, and purifying the cultivated water after completion of the cultivation with dissolved ozone to discharge to the outside. The method for cultivating groundwater-saving pesticide-free sprouts is described in detail. In the present invention, the cultivated water is recovered by recycling the cultivated water, and the cultivated bean sprouts are sterilized with ozone and decomposed organic materials to prevent corruption. Produce bean sprouts.

Currently, the amount of groundwater used for cultivating bean sprouts is estimated to be enormous. Since the groundwater resources are limited, a large amount of groundwater is wasted when cultivating bean sprouts in a conventional manner. It is expected to be exhausted. When cultivating bean sprouts according to the present invention is secured 30L per 1kg of dry soybeans can be grown because it is possible to cultivate the groundwater every time for the cultivation of bean sprouts and is differentiated from the existing cultivation method of discarding the sprinkled water. If you cultivate by spraying 8 times a day for 5-6 days for cultivating soybean sprouts, 40-48 times of watering is required, but according to the present invention, groundwater can be used for 5 days with the amount of groundwater of once watering. Compared to at least 1/40, it is an environmentally friendly cultivation method to prevent waste of groundwater resources.

In addition, in the existing cultivation method, the groundwater with low water temperature is directly used, so the sprouts being grown are exposed to low temperature every time they are sprayed, and the growth is contracted. Since there is a lot of waste and the cultivation temperature is high, the growth of perishable microorganisms increases, so there is a disadvantage in that the rot of soybean sprouts being grown. In the present invention, since the cultivated water is circulated and used continuously, the temperature of the cultivated water is maintained at 20 ° C. equal to the temperature of the grower, so that the cultivation period can be completed by at least one day shorter than the cultivated by the conventional method. Therefore, the environmentally friendly cultivation method that can simultaneously save energy and groundwater for the cultivator warming is differentiated from the existing cultivation method. Referring to the cultivation method of the present invention as described above step by step (a) the cultivated water is insulated Storing in a storage tank, (b) sterilizing and purifying the cultivated water for 20-30 minutes by ozone aeration, and (c) any one selected from chitosan, germanium, and elvan (D) spraying cultivated water with a small amount of dissolved ozone in the cultivator adjusted to 20 ° C. using a nozzle for 3 minutes, and (e) collecting the sprinkled cultivated water through the drip tray. Recovering to the small settling tank, (f) transferring the cultivated water recovered to the small settling tank to the storage tank by a circulation pump, and (g) sterilizing the cultivated water transferred to the storage tank with ozone. And (h) continuously circulating the cultivation water until the cultivation of the bean sprouts is completed and purifying the cultivated water after completion of the cultivation with dissolved ozone to discharge to the outside. The method will be described in more detail as follows. (A) The storage tank surrounded by the thermal insulation material serves to keep the temperature of the cultivation water constant. In general, 3 to 4 tonnes of water is sufficient to crush 100 kg of seeds. Therefore, if a 5 ton water storage tank is installed, it is advisable to adjust the planter's facility to a size that can heal 100 Kg of seeds (100 boxes can be installed when using 1.0 Kg cultivation containers). Dissolve ozone in cultivated water using Sterilization concentration is higher than 1.0ppm, and when the ozone concentration is low enough to not damage soybean sprouts after a certain period of time after the sterilization treatment, it is sent to the planting water. When ozone levels are low enough to not damage bean sprouts, they are sent to the farms for watering. Since the half-life of ozone varies depending on the turbidity of bean sprouts grown, the grower needs to learn a suitable time in the production process after ozone treatment. This process oxidizes the organic substances secreted from soybeans and sterilizes it to significantly reduce the concentration of microorganisms and keeps the dissolved oxygen in the growing water higher than ordinary pure water. (C) When growing soybean sprouts according to the present invention. In order to reinforce the food functionality of the bean sprouts by cultivating by adding various natural substances to the cultivation water can increase the food functionality of the bean sprouts. The natural material is preferably chitosan, germanium, or elvan (d). The temperature of the grower is maintained at 20 ° C., which is the growth temperature of the bean sprouts, and water is sprayed through the nozzle. If the room temperature is maintained at 20 ℃, the cultivated water is kept at 20 ℃ during the spraying without any temperature treatment, and the temperature is kept at a constant temperature during circulation because the thermal tank is used. It is installed at the bottom of the cultivation container to recover the total amount of water, and the small sedimentation tank can be about 100L in size and allow large and heavy impurities to precipitate as the cultivation water is recovered. In addition, a filter such as a mesh is attached to the water exiting portion of the small sedimentation tank to remove impurities having a size enough to block the sprinkling nozzle. (F) A circulating pump is used to remove cultivated water from the small sedimentation tank to the storage tank. (G) The cultivated water circulated to the storage tank is sterilized again by ozone after 3 hours and then sprinkled again. (H) The recycling of the cultivated water causes the turbidity and microbial concentration of the water to contaminate the sewage system. Becomes Therefore, after the cultivation is completed, the water flowing out is once again discharged by sufficiently purifying with a high 1.0 ppm dissolved ozone.

According to the bean sprout cultivation method according to the present invention consisting of the steps as described above can be easily applied to mass production of the traditional bean sprout cultivation method used by manually recycling the water, the use of high concentration dissolved ozone is the organic component secreted from the bean sprouts Oxidation prevents the increase of turbidity and greatly increases the amount of dissolved oxygen. In addition, because it inhibits the concentration of microorganisms by strong sterilization action, only the water that is reduced during the cultivation period of 4 to 5 days is to be supplemented. In this cultivation method, since bean sprouts take 4 to 5 days from the mortar stage to the harvest, soybean sprouts can be grown without spoilage even if the total number of watering required for this, ie, 24 to 40 cycles, eliminates the use of pesticides. You can do it. In addition, before the cultivation process is completed and the cultivated water is discharged to the sewerage, there is an advantage that can be prevented by water pollution by purifying and discharged for 20 to 30 minutes at 1.0 ppm or more of high dissolved ozone.

Hereinafter, the present invention will be described in detail by way of examples.

<Example 1>

For bean sprouts production, put the selected bean sprouts in a growing box and crush them, and start cultivation at 20 ℃. The water sprayed on the bean sprouts is collected in a collecting tank through a recovery pipe, and the recovered cultivated water is treated with ozone before the next watering to decompose decaying microorganisms and suspended organics to purify the cultivated water and increase the concentration of dissolved oxygen necessary for growing bean sprouts. give.

The ozone treatment time is controlled by considering the vitality of the soybean and the concentration of suspended organic matter (10 ~ 20 minutes). The ozonated cultivated water is immediately sprayed on the bean sprouts by the circulation pump. This process is repeated until the cultivation is completed. Complete the cultivation. The number of sprinkling increases and decreases with the growth of bean sprouts up to 8 times a day and completes cultivation after 5 days. This method is similar to conventional bean sprout cultivation method using Tteoksiru, so it can reproduce the taste and form of traditionally cultivated bean sprouts without using any pesticides (growth regulators), which is different from the existing cultivation method.

< Example 2>

When cultivated in the same manner as above, natural substances such as calcium, germanium, chitosan, etc. are added to the cultivated water to enhance the food functionality of the bean sprouts. Since the cultivated water is recycled, the growing sprouts absorb and accumulate the processed functional substances sufficiently, thereby improving the food functionality of the sprouts. Therefore, when reinforcing the functionality by cultivation recirculation method, the functional material content of soybean sprouts can be significantly increased compared to the cultivation system by passing the functional material when cultivating water to add or sprinkling the functional material in the conventional invasion step. The number of times of watering and the growing period are the same as in Example 1.

Bean sprout cultivation according to the present invention can dissipate the consumer's doubts about the use of pesticides, such as growth regulators and can provide soybean sprouts with enhanced food stability can contribute to the improvement of public health, and a huge amount of groundwater resources are currently consumed in cultivating bean sprouts However, it can be greatly reduced, which will greatly contribute to the conservation of groundwater resources.
