AI Technical Summary
Existing food testing and sampling devices can only extract one set of samples, which cannot meet the high-efficiency sampling needs of large batches of food, resulting in low overall efficiency.
A food sampling device including a pretreatment cylinder and a sampling mechanism was designed. The pretreatment cylinder is driven by a motor to crush food samples. The sampling mechanism uses a lifting frame and a retractable base plate to separate the solid and liquid samples of multiple groups of samples. The lifting frame controls the sampling test tubes to sample in the material stacking box and collects liquid samples through a liquid sieve plate and a drain pipe.
It enables simultaneous sampling of multiple food samples, improving sampling efficiency, especially the separate processing of solid and liquid samples, and the appropriate crushing of samples to size facilitates subsequent analysis and detection.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of food safety testing technology, specifically a food sampling device for food safety testing. Background Technology
[0002] Food safety testing involves detecting harmful substances in food according to national standards, primarily targeting harmful and toxic indicators such as heavy metals and aflatoxin. An important aspect of food science and engineering is the introduction and application of chemical unit operations, and the development of food engineering unit operations, thereby promoting the food industry towards large-scale, continuous, and automated development.
[0003] According to a patent application published on the internet (authorization announcement number: CN219265783U), "This utility model discloses a rapid sampling device for food testing, relating to the technical field of food testing equipment. It includes a sampling cylinder with a rotating mechanism that extends deep into a grain silo. A collection chamber is also provided inside the sampling cylinder. A switch door connected by a pin is provided on the surface of the sampling cylinder. An opening assembly for pulling the switch door open is also provided inside the sampling cylinder. The device works by placing the sampling cylinder vertically above a grain pile, then a servo motor drives a rotating rod to rotate, which in turn drives a drill bit to rotate. The drill bit, through rotation, pushes the entire sampling cylinder deep into the grain silo. After the sampling cylinder is inserted into the grain pile, the support is removed. Rotating a crossbar drives the rotating cylinder, which in turn moves a guide rod and a slider, causing a spring to rebound. This opens the switch door, allowing the grain pile to fall into the collection chamber, thus solving the problem of collecting grain from each layer of the grain silo."
[0004] Based on the above, the applicant believes the following deficiencies exist:
[0005] The rapid sampling device for food testing includes a collection tube. The device is inserted into the grain pile to collect samples. However, this device can only extract one set of samples, which is not convenient for sampling large quantities of food. The overall efficiency is low and it cannot meet the needs of testing large quantities of food. Utility Model Content
