Description

Inspection module of egg quality inspection machine

The detection module of the poultry egg quality detection machine of the present invention is mainly applied to the quality detection technology of poultry egg cracks.

Eggs are the main source of protein intake for Chinese people. Over the past 60 years, the number of eggs consumed in Taiwan has increased tenfold, from 30 eggs per person per year to more than 300 eggs, almost every 1 to 2 days. The quality of eggs is not only closely related to food safety, but also affects the taste and processing characteristics (such as gelation, emulsification, foaming, etc.) of the finished food. In recent years, Taiwan’s food safety problems have continued. Food raw materials have caused serious food safety problems. Government departments are expected to formulate new laws to strengthen inspections and actively improve the food raw materials management mechanism, hoping to start from the source management to stop the hunger strike safety problem. In order to meet the health, safety and quality requirements of eggs, it is necessary to carry out inspections for cracks in the egg shell, blood spots, and meat spots, and to pick out damaged or poor-quality eggs to ensure the health of the Chinese people.

At present, Taiwan and Southeast Asian countries mostly use manual methods to test the quality of eggs. This method is not only without accurate standards, but also quite labor-intensive. In response to the rapid development of the global economy, labor costs will increase significantly in the future, and automated testing is imperative. If there are cracks in the fresh eggs of commercial eggs and duck eggs, the shelf life will be greatly reduced, and even the breeding of Salmonella bacteria. The processed eggs are mostly made of preserved duck eggs and salted duck eggs for sale. If they are laid on duck eggs Or luck The collision in the transportation process causes the existence of cracks, so that in the post-processing and curing process, once excessive drugs or impurities infiltrate from the cracks, it will affect human health and the success rate and quality of the final product. Therefore, whether it is fresh eggs or processed eggs , The accuracy and precision requirements for crack detection are strict, so it is hoped that a good raw material management mechanism can be established to stop related food safety issues from source management.

The global output value of automated egg inspection is estimated to be tens of billions. At present, many major egg cleaning and grading equipment manufacturers in China have no automatic crack detection function for their products, which cannot more accurately meet the current egg inspection needs. The international competitiveness is insufficient and cannot be compared with the Netherlands and Japan. Waiting for the international giants to compete for the pie of egg quality testing.

The inventor is currently engaged in the manufacture and design of related products, and has accumulated many years of practical experience and experience. Aiming at the egg equipment in my country only has the function of cleaning and grading packaging, it lacks the function of crack quality detection, and cannot meet the quality requirements of modern eggs. It does not have international competitiveness, and actively invests in the spirit of innovation and improvement to complete the inspection module of the egg quality inspection machine.

The technical means used in the invention to solve the problem and the effect of comparing with the previous technology are: in order to solve the problem that some poultry eggs often stick to feces, soil and other foreign objects that affect the accuracy and yield of crack detection, the present invention uses a crack detection unit model on the one hand. Assembled and customized, it can be directly installed in the egg cleaning and grading equipment of major factories, so that the egg equipment can meet the current food testing requirements. At the same time, the number of detection points is reduced to 8 points, and the percussion system is designed by simulating manual percussion. A microphone sound insulation system is also added to prevent other sounds from interfering with the judgment, and the feed and eggs are added. The grading system completes a simple prototype machine, making my country's egg equipment internationally competitive, so as to enter Southeast Asia and other international markets. The invention helps the poultry and egg processing industry to increase the speed of screening poultry egg cracks and improve the success rate of processed products, and finally develops an intelligent poultry egg crack detection system.
