Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a pretreatment device for heavy metal detection of tea leaves. Background Art

[0002] Tea is one of the most widely consumed beverages in the world, and its quality directly affects the health of consumers. Among them, the heavy metal content in tea is one of the important factors affecting its quality. Excessive heavy metals not only affect the taste of tea, but may also be harmful to human health. Therefore, it is very important to detect the heavy metal content in tea.

[0003] At present, the tea heavy metal detection equipment on the market mainly determines the heavy metal content in tea by chemical reaction of tea samples and then through spectral analysis and other means. However, such equipment usually needs to go through a complex sample pretreatment process, including sample grinding, dissolution, filtration and other steps, to obtain a sample suitable for analysis. This pretreatment process is time-consuming and cumbersome, and often requires professional operators to perform, which limits its efficiency and convenience in practical applications.

[0004] In addition, most of the current tea grinding equipment is single-function and cannot effectively limit the particle size of the ground tea leaves. This makes the grinding results each time likely to vary greatly, leading to deviations in subsequent heavy metal testing results, affecting the accuracy and repeatability of the test results.

[0005] Therefore, there is an urgent need for a pretreatment device for heavy metal detection in tea, which can quickly grind the sampled tea leaves and limit the particle size of the ground tea particles, providing a basis for subsequent experiments and improving the efficiency and accuracy of detection.
