Egg white height measurement apparatus and the measurement method using it}

The present invention relates to an egg white height measuring apparatus of eggs, and more particularly, to an egg white height measuring apparatus and method for measuring egg white, which can objectively determine egg grade by automatically measuring egg white height.

As consumers' preference for high quality livestock products changes, the need for egg grading is increasing day by day.

The egg grade currently being evaluated is evaluated by the appearance test, the condition of egg shells by light inspection, the condition of air chamber, egg yolk, egg white, and then the condition of egg yolk, the height of rich egg white, and egg white by halan test. Inspect the condition and the presence of foreign substances.

A rich egg white is a egg white that firmly surrounds the egg yolk, and refers to egg whites that are gathered around the egg yolk without spreading in Harlan. The height of the rich egg white is one of the most important variables for determining the Haugh unit used for egg grading along with egg weight.

Conventionally, in order to measure egg white height, an operator manually measured egg white height. For example, the operator randomly selected a point about 10 mm from the interface between egg yolk and egg white in a wide direction in the direction of the spread of the egg yolk and egg white, and measured the height of the egg white.

However, this manual measurement method is subject to the operator's subjectivity in the selection of the measurement point, there was a difficulty in serving as an objective judgment indicator because there were a number of problems, such as the egg white height of the same egg is changed depending on the skill of the operator.

In addition, a device for measuring egg white height using ultrasonic waves has been developed (EggTester.Com, 2008), but it is also difficult to flexibly respond to the spread direction of rich egg white and it is not used to find an accurate measuring point. Not.

In addition, in the measuring method using the egg white height measuring apparatus of the egg according to the present invention, the final egg white height is calculated by averaging the second and third ranks among the top three.

Egg egg white height measuring apparatus and measuring method using the same according to the present invention is to objectively and quickly accurate egg white height because the probe is composed of a reference probe and a plurality of measuring probes to automatically lift and contact the egg egg by using a drive unit It is possible to measure and further improve the reliability of grading eggs.

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

1 and 2 are a perspective view and a side view showing the egg egg white height measuring apparatus according to the present invention.

Referring to the drawings, the egg white height measuring apparatus according to the present invention is a halan dish 10, a probe 20 composed of a plurality of probes, and a drive unit 30 for operating the probe 20 Includes,

The harlan dish 10 is a flat plate that can hold eggs and contain egg yolk (1a), commonly called a yellow egg, and egg white (1b), a white egg. The harlan dish 10 has a seating groove 12 so that the yolk 1a can be always placed in a constant position. Preferably, the seating recess 12 is provided at the center side of the harlan dish 10. The average diameter of egg yolk is about 40 mm, and the seating groove 12 has a diameter of about 38 mm based on this.

The meter reader 20 includes one reference probe 22 and a plurality of measurement probes 24. Each probe 22 and 24 is installed downward on the base plate 21 via the elastic means 23. The reference probe 22 has a longer length than the measurement probe 24, so that the reference probe 22 first contacts the egg which is egg-layed during egg white measurement. The measuring probes 24 consist of a plurality, and in this embodiment, eight are arranged at equal intervals on concentric circles, and the reference probes 22 are located between them. The measuring probe 24 is provided in the range of 60 mm in diameter from the center of the seating groove 12. This is because, as described in the prior art, the position corresponding to 10 mm from the boundary between egg yolk and egg white is the current egg white height measurement standard.

The driving unit 30 for operating the meter reader includes a support for supporting the meter reader 20, a motor 31 for elevating the meter reader, and a controller (not shown) for controlling the meter. The support is composed of a vertical frame 32 and a horizontal frame 33, the motor 31 is seated on the upper end of the vertical frame (33). The motor 31 is preferably a stepping motor capable of finely controlling the position of the meter reader 20, and the controller includes a circuit for driving and controlling the motor. By the operation of the motor 31, the arm 34 on which the meter 20 is fixed moves up and down toward the harlan dish 10.

Then, look at the operation of the egg white height measuring apparatus of the egg configured as described above.

When the egg is harlanted and contained in the harlan dish 10, the controller operates the stepping motor 31 so that the meter reader 20 descends.

The descending meter 20 is the first probe 22 is in contact with the egg, and then each measuring probe 24 is in contact with the egg. As shown in FIG. 3, since the yolk 1a is accommodated in the seating groove 12 at the time of Harlan, at least one measuring probe 24 at a position 10 mm away from the boundary between the yolk and egg white is at least one egg white 1b. Contact.

When each measuring probe 24 comes into contact with the egg white, electric current flows between the reference probe 22 and the measuring probe 24 by electric conduction, and this current signal is output to the controller. The controller calculates the egg white height based on the number of steps applied to the stepping motor 31 at the moment the output signal is detected. One step of the stepping motor 31 is calculated to be 0.025 mm.

Table 1 shows that the probes tended to contact the eggs when they were harlaned. As a result, three of the eight probes touched the rich egg white, and the average of the three probes contacted the weeping egg white (the thin and wide part surrounding the thick egg white). There were 0.3 measurement probes in contact with the egg yolk holding the egg yolk, and 1.5 measurement probes in contact with the interface between the rich egg and the egg white egg. Based on these experimental results, in the present embodiment, when measuring egg white height using eight measuring probes, it was determined that an average of three measuring probes were effective regardless of the spreading direction of the rich egg white.

Table 2 shows an example of calculating the egg white height by using the egg white height measuring apparatus of the egg according to the present invention. As described above, the movement distance from the origin is calculated from the number of steps applied to the stepping motor 31 at the moment when the eight measuring probes 24 contact the egg white, and the movement distance is converted to the egg white height.

The measured egg white heights are listed in order of height, taking only the egg white heights for the top three and calculating their average value as the final egg white height.

On the other hand, there is a case where a large deviation occurs between the egg white height of the highest value and the egg white height of the next-order value, because the measurement probe 24 is in contact with the lead rather than the rich egg white. Therefore, in order to prevent such a case, the highest egg white height may be excluded and the egg white heights of the top two next order values and the third rank values may be averaged to calculate the final egg white height.

FIG. 4 shows the eggs in a harlan state, which are egg yolk 1a, rich egg white 1b, weeping egg white 1b ', and string 1c, respectively.

 On the other hand, in the above embodiment is to measure the egg white height of the egg, but the present invention is not limited to this can also be applied through a suitable deformation and modification as a device for measuring the irregular surface height of an aqueous object of course to be.
