Description

Technical Field

[0001] This utility model belongs to the field of food standard sample sieving technology, and more specifically, relates to a vibrating sieve device for preparing dry powder food standard samples. Background Technology

[0002] Food standard samples are food samples containing known concentration characteristics and exhibiting uniform and stable food matrix features. They are typically prepared by adding specific compounds to a negative food matrix and employing special processing techniques. After the characteristic values ​​are collaboratively determined by multiple authoritative institutions, they can be used for routine laboratory quality control, inter-laboratory comparisons, or evaluation and verification of testing methods. Uniformity is one of the important quality indicators for dry powder food standard samples; the more uniform the particle size distribution, the better the overall uniformity. Therefore, sieving the samples before repackaging is a crucial step in the preparation of dry powder food standard samples.

[0003] Traditional sieving equipment mainly includes two types: manual sieves and open vibrating sieves. Manual sieves have low sieving efficiency and small sample processing capacity. At the same time, both of these sieving methods have the problem of powder scattering during the sieving process. For powdered samples containing chemicals, sample scattering can cause pollution to laboratory personnel and the experimental environment. Utility Model Content
