AI Technical Summary
Existing technologies for food testing equipment in customs port scenarios suffer from low pulverization efficiency, high residue rates, and the risk of cross-contamination, making it difficult to meet the needs for rapid, safe, and reliable testing.
This portable food testing device features a modular design, integrating a food safety testing instrument with a pulverizing component. It utilizes a three-stage spring-loaded pulverizing blade assembly and a magnetic discharge baffle to achieve dynamic sealing and scraping, ensuring sample transport within a closed channel. Combined with the opposite-polarity magnetic attraction structure of the locking component, it achieves equipment stability and high-frequency sterilization.
It improves the crushing efficiency of complex samples, reduces the residue rate, adapts to rapid on-site inspection at customs ports, solves the problems of low efficiency and cross-contamination, and achieves efficient and safe sample pretreatment.
