Food quality inspection several instruments introduced
Food quality inspection includes food screening, bulk density determination, gluten content determination and so on. Among them, this article mainly introduces the grain filter and the bulk density tester, which are used to screen grain, and determine the bulk density of wheat and corn.
The grain filter is a kind of instrument used to test the impurity content of grains and oil samples, the content of rice and wolfberry powder, and determine the quality grade of the grain filter. It is a kind of special instrument for determining the pest density and the level of insect grain. Grain filter is also called computer filter and electric filter. It is developed according to the GB5494-85 "National Standard for Inspection of Impurities and Imperfect Grains of Grain Oil". After the grain filter and grain selection sieve are matched, it is widely applied to the screening and determination of grain and oil, and is the necessary screening and grading equipment for agricultural breeding. Cereal filters are widely used in the food sector in the acquisition, storage, processing, storage and transportation and scientific research, health, foreign trade and other related departments. The grain filter has the advantages of compact structure, stable operation, stable performance and convenient operation. In the electronic control part, 89LE52 single-chip microcomputer is used to control forward rotation and reverse rotation, and the controlled forward and reverse rotation time has high precision.
Bulk Densitometer: The Bulk Densitometer is used to measure the bulk density of crops such as wheat, rice, sorghum, and corn. Based on the LS/T3701-1993 "HGT-1000 Grain Cessel Container" standards and standards in the "quote standard" and GB1353-2009 "maize" new national standard in the measurement of grain bulk density requirements developed. It is an indispensable instrument for food quality inspection and plays a key role in the acquisition, storage and processing of grain.
Food is fundamental to the national economy. Only by ensuring the good quality of food can it be possible to talk about national development and national development. The guarantee of grain quality is achieved through different instrument products. In addition, in the field of seed detection, there is also a library of germplasm resources for storing different quality germplasm resources, which is also one of the promising instrument products in recent years.
