Description

Technical Field

[0001] The utility model relates to the technical field related to grain quality detection, and in particular to a food quality detection device. Background Art

[0002] Rice is often the main food for people. The detection items such as broken rice, imperfect grains, maximum limit of impurities, pesticide residues, moisture, yellow rice, mixing, cadmium, arsenic, lead, mercury, etc. are important indicators of rice detection. There are many rice detection items, and they need to be tested before sales to ensure people's food safety. The broken rice rate refers to the percentage of rice grains that are crushed into small pieces during the rice processing process. In rice production, the broken rice rate is an important indicator because it affects the quality and price of rice. The higher the broken rice rate, the worse the quality of rice and the lower the price. The broken rice rate standard stipulated by my country is: no more than 5%, that is, there must be no more than 5 kg of broken rice in 100 kg of rice.

[0003] At present, most of the broken rice detection methods of rice are to put the sampled and weighed rice into a sieve plate for sieving, and then the broken rice in the sample rice is sifted out, and then the percentage of broken rice in the sample rice is obtained to evaluate the overall rice quality. However, in actual operation, the mesh holes of the sieve plate are often blocked by rice, which affects the screening of broken rice. The staff is required to frequently conduct the sieve holes during the screening process to avoid the situation where the broken rice cannot be sieved and thus affect the final rice quality assessment. The operation is cumbersome, time-consuming and labor-intensive. Utility Model Content
