The present invention relates to a specific gravity measuring method and measuring apparatus of fresh ginseng, more specifically, in order to measure the weight of the fresh ginseng in order to measure the weight of the fresh ginseng in order to measure the weight of the fresh ginseng in order to be able to measure the weight of the fresh ginseng. It relates to a specific gravity measurement method and measuring apparatus of one ginseng to increase the accuracy of specific gravity of fresh ginseng.

In general, fresh ginseng is classified by the appraiser based on the purchase quality appraisal standard and classified into 1 ~ 4 grades and out of grade (5th grade). The evaluation criteria of the purchase quality of the fresh ginseng are the head, the body, the leg part, and the weight, the color and the crack of the fresh ginseng, and the appraiser judges the grade of the fresh ginseng by comprehensively judging these feeling standards.

However, as the grading of fresh ginseng is dependent on human sensuality, the grading of fresh ginseng cannot be judged by subjective evaluation by the appraiser, and accordingly, the weight of fresh ginseng is measured separately. Reflecting is used in some.

The method of measuring the specific gravity of the ginseng commonly used in the present is to measure the weight of fresh ginseng in the air, and then after dipping the fresh ginseng in a tank filled with water and measuring the weight of the fresh ginseng in water, To calculate. As is well known, the specific gravity of water in Equation 1 is dependent on temperature, and the specific gravity of water at 4 ° C. is based on 1.

In Equation 1, S is the specific gravity of fresh ginseng, S _t is the specific gravity of water, W is the weight of fresh ginseng, W _t is the weight of fresh ginseng.

However, when the fresh ginseng is deposited in water in order to measure the specific gravity of the fresh ginseng, it is difficult to accurately measure the ginseng weight by buoyancy due to air bubbles present on the surface of the fresh ginseng. In particular, if you want to measure the specific gravity by dipping fresh ginseng in water, if the specific gravity is not measured in a short time, the roots of live ginseng slowly absorb water and change the specific gravity, which is required to measure in a short time.

Therefore, the present inventors have studied a method and apparatus for quickly measuring the specific gravity of fresh ginseng in a short time by quickly removing air bubbles present on the surface of the plant in order to measure specific gravity by dipping fresh ginseng in water. The invention has been completed.

Therefore, the present invention is to determine the specific gravity of fresh ginseng in a short time by measuring the weight of the fresh ginseng in a short time by quickly removing the bubbles present on the surface of the fresh ginseng when you want to measure the weight by immersing the fresh ginseng in water The purpose is to provide.

In order to achieve the above object, the present invention deposits ginseng, which has been weighed in air, in the water inside the tank filled with water, and measures the weight of the ginseng deposited in water, and then uses the ginseng weight measured before and after immersion. In the specific gravity measurement method of the fresh ginseng to calculate the specific gravity of the fresh ginseng, the specific gravity of the fresh ginseng characterized by removing the air bubbles on the surface of the fresh ginseng by applying a vibration wave to the fresh ginseng before measuring the weight of the fresh ginseng deposited in the water Provide a measurement method.

The present invention also provides a balance for weighing in order to achieve the measuring method effectively; Water is filled in the tank, and the top of the tank is formed to be opened and closed; In one end of the hook is connected to the scale is formed, the other end of the ginseng fixture is formed with a net that can put the ginseng; In the specific gravity measuring device of ginseng, the outer lower portion of the tank vibrated by the ginseng deposited inside the tank The present invention provides a specific gravity measuring device of ginseng, characterized in that the vibration wave generator for removing the air bubbles present on the surface of the ginseng.

Hereinafter, the present invention will be described in more detail.

In the present invention, in order to more accurately measure the specific gravity of the fresh ginseng, the fresh ginseng, which has been weighed in air, is deposited in the water inside the tank filled with water, and the bubbles present on the surface of the fresh ginseng are applied to the fresh ginseng deposited in the water by applying a vibration wave After removing, measuring the weight of the fresh ginseng bubble is removed and provides a specific gravity measurement method of fresh ginseng using the weight of the fresh ginseng measured before and after immersion.

That is, in the present invention, it is generally difficult to accurately measure the weight of the ginseng, which is measured on the surface of the ginseng, in the process of immersing the fresh ginseng, which is weighed in air, in the water. In order to solve the problem, before measuring the weight of fresh ginseng deposited in the water, vibration wave is applied to the fresh ginseng so that the air bubbles on the surface of the fresh ginseng can be removed quickly, thereby increasing the accuracy of the weight measurement. The biggest feature is that it allows to measure more accurately.

When the vibration wave is applied to the fresh ginseng, the vibrating wave vibrates the fresh ginseng, including water, and the generated vibration helps the bubbles on the surface of the fresh ginseng to be easily removed and removed. Therefore, it is possible to measure the specific gravity of the fresh ginseng more accurately, and in particular, it is possible to remove the air bubbles on the surface of the fresh ginseng within a short time, so that the specific gravity of the fresh ginseng can be accurately measured within a short time. The vibration wave is able to sufficiently remove bubbles existing on the surface of the fresh ginseng when the fresh ginseng is immersed in water and added for 3-5 minutes.

Here, the specific gravity of the fresh ginseng is first measured by measuring the weight of the fresh ginseng in the air and then deposited in the water to measure the weight of the fresh ginseng, and using the measured ginseng weight, the specific gravity of the fresh ginseng is calculated based on Equation 1. This specific gravity measuring method is equivalent to that which can be easily carried out in the art, but in the present invention, in order to increase the accuracy of the specific gravity measurement value of fresh ginseng, by dipping fresh ginseng in water to measure the weight of the fresh ginseng by applying vibration waves to the fresh ginseng After removing bubbles on the surface, the weight of fresh ginseng is measured. If you want to close the cover of the tank ginseng fixture is to hang the hook in the fixing groove formed on the inner periphery of the upper tank.

At this time, in the case of air weight or underwater weight of ginseng can be easily measured by using a known scale, hooks are connected to the scale at one end for easier measurement, and the other end can put ginseng It is good to use a ginseng fixture with a mesh. In addition, since the specific gravity of the ginseng may not be floating because it is not 1, it is preferable to hang the weight on the net to prevent this.

More specifically, the process of measuring the specific gravity of fresh ginseng using the fresh ginseng fixture will be described. First, the weight of the weight and the net weight in the air is measured using a scale, and then it is submerged in water and the vibration wave is applied. Measure the net weight. Then, put ginseng in the net, measure the weight of ginseng, weight and net in the air, dip it in water, apply vibration wave, and measure the weight of ginseng, weight and net in the water. The weight of the fresh ginseng in the air is obtained by subtracting the weight of the fresh ginseng, weight and net in the air, and the weight of the fresh ginseng, weight and net after applying the vibration wave. When the net weight is subtracted, the underwater ginseng weight after the vibration wave is obtained is obtained. The specific gravity of fresh ginseng can be calculated by substituting the weights of fresh ginseng into Equation 1, and since the specific gravity of water is known for each temperature, the specific gravity of fresh ginseng can be calculated using the specific gravity at that temperature after measuring the water temperature. Will be. Preferably, if the above measurement process is carried out in 4 ℃ water, the specific gravity of the water is 1 so that it is easy to calculate the specific gravity of ginseng. Here, the weight of the weight and the net under the same conditions is because the vibration wave is applied before the weight of the weight and the net soaked in the water is applied before the weight is measured after the ginseng and the weight and the net are soaked in water. This is to measure the ginseng weight in the water more accurately by subtracting.

At this time, the ginseng can measure the specific gravity by putting only one root in the net or by measuring several roots as necessary. Can be obtained, but this can be done selectively.

The tank used to measure the weight of fresh ginseng is filled with water inside, and the cover is opened and opened at the top, and the amount of water to be filled is enough to immerse the fresh ginseng. The opening and closing of the top cover of the tank is intended to allow the weight of the ginseng to be measured while the scale and the ginseng fixture are in line when measuring the weight of the ginseng in the water. Preferably, the tank is used to have a constant temperature function.

At this time, the vibration wave can easily vibrate the ginseng and water deposited in the water can be selected from known ultrasonic waves, sound waves or low frequency to the fresh ginseng, preferably applying ultrasonic waves to remove the bubbles present on the surface of the fresh ginseng Effective in Sending the vibration wave can be easily performed by driving the vibration wave generator on the outer bottom of the tank.

In order to remove bubbles in the surface of the fresh ginseng by applying vibration waves to the ginseng, the tank and the vacuum pump are connected to make it easier to remove bubbles, and the vacuum pump is driven to vacuum the upper surface of the water surface inside the tank. It is good. In this way, if the upper part of the surface is made in a vacuum state, bubbles on the surface of the ginseng are quickly removed, thereby shortening the measurement time of the specific gravity.

At this time, it is preferable to apply a high vacuum pressure to the vacuum pressure, but it is not necessarily limited thereto. This is because the purpose of the vacuum is not to be in the vacuum itself, but to remove it easily by increasing the volume of air attached to the surface by vacuuming.

In addition, it is good to circulate the liquid in the tank in the process of applying the vibration wave to the fresh ginseng. By circulating the liquid in the tank in this way it is possible to more easily remove the air bubbles present on the surface of the ginseng.

The flow rate is also good to circulate the liquid in the tank at a high speed, but it is not necessary to limit this, and after circulating the liquid, the measurement must be performed while the liquid circulation is stopped so that the measured value is not affected.

In order to achieve the above specific gravity measuring method more effectively, the present invention provides a specific gravity measuring apparatus. This will be described in more detail with reference to the accompanying drawings.

At this time, the fresh ginseng was measured the middle piece (diameter 2.5 ~ 3.5cm) and large piece (diameter 3.5cm or more).

Using the measured values to calculate the weight of the water after applying the weight of the ginseng and ultrasonic waves in the air, and substituted by Equation 1 to calculate the specific gravity of the ginseng, the results are shown in Table 1 below.

At this time, the ginseng was measured the middle and large pieces respectively.

division Example 1 Comparative Example 1 About Medium About Medium Weight and net weight in air (A) 310.99 311.50 310.99 311.50 Underwater weight and net weight (A _t ) 241.10 241.50 237.40 237.80 Fresh ginseng, weight and net weight in air (A + W) 2649.00 1288.70 2649.00 1288.70 Fresh ginseng, weight and net weight in water (A _t + W _t ) 290.40 250.00 100.00 173.00 Weight of fresh ginseng in air (W) 2338.01 977.20 2388.01 977.20 Weight of fresh ginseng (W _t ) 49.30 8.50 -137.40 -64.80 Specific gravity of fresh ginseng = W / (W-Wt) × 1 1.02 1.01 0.944 0.938

As shown in Table 1, in the case of Example 1 in which the specific gravity of ginseng was measured by treating the ultrasonic wave according to the present invention, it can be seen that the value is higher than that of Comparative Example 1 in which the specific gravity was measured without using the ultrasonic wave. The specific gravity of Comparative Example 1 was lower than that of Example 1 in Example 1 that the bubbles on the surface of fresh ginseng were removed, resulting in a high weight in water, whereas Comparative Example 1 was present on the surface of fresh ginseng It can be seen that the air bubbles made lightly the weight of fresh ginseng.

<Example 2>

In the specific gravity measurement device shown in Figure 4 by hanging the hook of the ginseng fixture on the scale to measure the weight of the weight and net in the air, after filling the tank with about 2/3 of water while maintaining the weight and the net at 4 ℃ After soaking in the ultrasonic generator was operated at intervals of 1 minute and the ultrasonic wave was applied to measure the weight of the weight and net weight in the water. After the weight and weight of the net was completed, the fresh ginseng was placed in the net completely removed, and the ginseng, weight and net weight were measured in the air. The fresh ginseng, weight and the net were immersed in water maintained at 4 ° C. Next, the ultrasonic generator was operated at an interval of 1 minute, and the weight of the fresh ginseng, the weight, and the net were measured. Using the measured values, the weight of the fresh ginseng after applying the fresh ginseng weight and the ultrasonic wave in the air was substituted into Equation 1 to calculate the specific gravity of the fresh ginseng according to elapsed time, and the results are shown in Table 2 below. . At this time, the vacuum pump and the circulation pump were not driven.

<Example 3>

After dipping weight and net in water and applying ultrasonic wave, weighing and dipping ginseng and weight and net in water, and then operating ultrasonic generator to apply ultrasonic wave and weighing each one minute Except for driving the ultrasonic generator and the vacuum pump together, the same procedure as in Example 2 was carried out to calculate the specific gravity of fresh ginseng according to the elapsed time, the results are shown in Table 2 below. At this time, the circulation pump was not driven.

<Example 4>

After dipping weight and net in water and applying ultrasonic wave, weighing and dipping ginseng and weight and net in water, and then operating ultrasonic generator to apply ultrasonic wave and weighing each one minute The specific gravity of fresh ginseng was calculated according to the elapsed time by the same method as Example 2 except that the ultrasonic generator, the vacuum pump, and the circulating pump were driven together, and the results are shown in Table 2 below.

Elapsed time Example 2 (weight) Example 3 (weight) Example 4 (weight) 0 min 0.95 0.95 0.95 1 minute 0.98 1.00 1.02 2 minutes 1.00 1.01 1.02 3 minutes 1.01 1.02 1.03 5 minutes 1.02 1.03 1.03 10 minutes 1.03 1.03 1.03 15 minutes 1.03 1.03 1.03 20 minutes 1.03 1.03 1.03

As shown in Table 2, it can be seen that the specific gravity increases as bubbles are continuously removed as time passes in Examples 2 to 4, but in the case of Example 2 treated only with ultrasound, specific gravity is kept constant after 10 minutes. It can be seen that in the case of Example 3, which was subjected to both ultrasonic and vacuum treatment, After 10 minutes, there is no change, and it can be seen that the combination of ultrasonic and vacuum treatment can shorten the specific gravity measurement time compared to the ultrasonic treatment alone. In particular, it can be seen that the specific gravity measurement time of Example 4, which measured specific gravity while circulating ultrasonic waves, vacuum treatment and water, was significantly shortened compared to other embodiments.

As described above, the present invention can more accurately measure the specific gravity of fresh ginseng within a short time by quickly removing bubbles present on the surface of fresh ginseng to measure the weight by dipping fresh ginseng in water for measuring specific gravity of fresh ginseng. Thus, there is a useful effect of providing a method and a measuring device for measuring the specific gravity of a ginseng.
