Electric filter picks "bone" from rice grains
To ensure food security, the responsibility is as heavy as Mount Tai. This may be the most profound sentence spoken by food inspection personnel. To do this, testers need to be exposed to a variety of food testing equipment, such as electric filters, during the work process. The working contents of electric filters and other instruments are often very detailed, and it can be said that picking bones from rice grains. Through the physical testing of sampling samples of food samples such as large impurity rate, small impurity rate, roughness rate, imperfection rate, and water content, the food quality can be determined to ensure food security.
The function of the electric filter is mainly used to detect the content of large impurities in the rice. Mix the uniform sample or weigh out 500 grams of rice through the balance, and then screen through the electric filter. The working process is roughly as follows: 500 grams of the sample is packed into a three-layer sieve like a "small steamer", fixed on an electric filter and rotated 60 times, and repeated three times. The final impurities will be separated from the rice, the upper layer is larger impurities, the middle layer is rice, the lower layer is a small sand and dust. Finally, weigh the impurities and rice separately.
The use of electric filters for the screening of food samples is not always possible at one time. It often requires multiple screenings and weighings. This work seems very boring and has the meaning of picking bones from rice grains, but it is indeed A very important test is not to be sloppy. The goal is to ensure the accuracy of the test report and provide guarantees for food security.
Now, with the application of electric screens and other grain detection instruments, the efficiency and precision of food inspection have greatly improved, providing a lot of convenience for food safety inspection, and providing important technical support for food security. . At the same time, these professional instruments also provide better services for farmers and ensure the stable development of the food industry.
