Description

Egg shell hardness testing system

The present invention relates to the testing technology of the hardness of egg shells, especially refers to testing the egg shells with a telescopic mechanism through a computer control device, using load element data reading, combined with the calculation and conversion of the control device, to display pressure data Compare with the database to understand the change of eggshell strength.

For a long time, the people have taken food as their heaven, which means that eating is the most important thing for the people. How to eat to be healthy, and how to eat to be nutritious; generally speaking, eating an egg a day is a basic nutrition that experts and scholars highly recommend. It is suitable for both young and old; due to the large demand, this has also resulted in the establishment of many chicken farms to supply the market’s demand for eggs; and in the process of commercializing the eggs produced by the nutritional chicken farms or the brooding chickens, the female The health of the chicken is very important because it will affect the quality of the eggs and the health of the next generation.

The factors that affect the quality of eggs are: (1) Heredity: Some chicken strains have better heat tolerance. For example, neck chickens with naked neck genes have better heat tolerance. Under high temperature in summer, their eggshell quality is better than ordinary chickens. Excellent; (2) Age of hens: As the laying time increases, the quality of the eggshells of laying hens will gradually decrease. Not only will the thickness of the aging hens become worse, the number of stomata on the surface of the eggshells will also decrease significantly; 3) Nutrition: The nutrition in the diet, especially the sufficient content of calcium, phosphorus and vitamin D, affects the quality of the eggshell most significantly. Vitamin D can promote the absorption of calcium and phosphorus. Excessive or insufficient calcium and phosphorus content in diets are not conducive to eggshell quality; (4) Diseases: Certain diseases such as Newcastle disease and respiratory diseases will reduce eggshell quality.

The composition of the eggshell has two parts. One is the accumulation of calcium crystals which is also the most important component of the eggshell, and the other is the protein outer membrane that coats the eggshell, called the surface membrane, which is required for the formation of the eggshell The nutrient must be supplied from the feed. Experiments can prove that increasing the acidity of the feed is harmful to the quality of eggshells. On the contrary, adding 0.5% to 1% sodium bicarbonate in daily food will significantly increase the egg production, increase the thickness of the eggshell, and produce defective eggs. cut back. If the eggshell hardness test can be responded to in time to adjust the feed The nutrient distribution ratio will strengthen the chickens and increase the hardness of the eggs.

Press, such as the "Eggshell Crack Inspection Method and Equipment" disclosed in the domestic patent No. I638601, the method includes the following steps: (a) Color the eggshell of the egg with paint so that the paint can penetrate into the eggshell crack ; And (b). Wash the eggs to remove the paint on the surface of the egg shell, leaving the paint in the cracks of the egg shell. In this way, the egg to be tested can be colored first, and then the color (pigment) on the surface of the egg shell can be removed. In this way, as long as the egg shell of the egg product has cracks, the paint will penetrate into the cracks of the egg shell during coloring. After cleaning, it still remains in the cracks in the eggshell. Therefore, any egg with cracks will have a predetermined color of eggshell cracks on the surface, which is easy to identify, while the egg without cracks is not; because the eggshell cracks have been stained before inspection The predetermined color is highlighted (that is, it becomes easy to identify and analyze). Therefore, whether by visual inspection or machine inspection (using computer image inspection system), the eggs with cracks can be easily and accurately identified The cracks in the egg shell can be more prominent with paint, so that subsequent visual inspection or machine inspection can easily identify the cracked egg.

Another domestic patent application No. 106123517 disclosed the "method for detecting and discriminating eggshell cracks", which disclosed a method for detecting and discriminating eggshell cracks, especially according to the principle of resonance detection method, using a microphone to record percussion data, and the signal The FFT analyzer performs signal analysis after fast Fourier conversion, and uses the FFT spectrum to distinguish the cracks of the egg. When the object is forced to vibrate by external force, the final vibration situation will produce certain specific frequencies, and these specific frequencies are called In the case of different structures or different materials, the resonance frequency displayed is different. The resonance detection method is to determine whether the egg is a normal product based on the difference in the resonance frequency of the excited egg. Directly detect the overall structure of the egg and successfully identify dirty eggs contaminated by soil and feces, which can reduce or ignore the impact of foreign objects on the egg surface.

In the previous case, the "egg shell crack inspection method and equipment" disclosed in Patent No. I638601 mainly used processed eggs, such as preserved eggs; the application for "Detection and Discrimination of Egg Shells" disclosed in Patent No. 106123517 "Crack method", which uses resonance detection to determine eggshell cracks, can be used as a basis for selecting egg processing, and reduce the loss of egg processing failures.

However, the aforementioned inventions are all inspection techniques for egg products before egg processing, and the present invention provides parameters for egg hardness, so early symptoms can be detected and treated early to reduce Fewer chicken losses or lower yields are part of the egg production technology. Therefore, the inventor of this case proposed a microcomputer measurement system for the quality inspection of eggshell thickness, which transmits the data to it through measurement and Internet of Things technology.
