AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

The utility model discloses a portable food detection sample rapid pretreatment device relates to food safety detection technical field, including lower box, baffle, rubber ring, upper box and discharge assembly. The lower box is inside with detection cavity, and the food safety detector is slidably installed in the detection cavity, and the side wall of the box is connected with the switch door in the side of detection cavity. The baffle is located at the upper end of the detection cavity and is connected with the inner side wall of the lower box. A discharge port is formed in the baffle. An inclined groove is formed on the upper surface of the baffle and around the discharge port. The rubber ring is connected to the lower surface of the baffle. The device integrates the food safety detector and the crushing assembly through the modular design of the upper and lower boxes. The portable operation of pretreatment before detection is realized. The upper box can be quickly disassembled and assembled to the lower box, solving the core problems of low efficiency, cross contamination and poor low-temperature adaptability in the prior art.
