Description

Technical Field

[0001] This utility model relates to the field of food testing technology, specifically to an integrated automatic grinding and extraction machine for food testing samples. Background Technology

[0002] The automatic grinding and extraction machine for food testing samples is a highly integrated laboratory device that integrates these steps into one system, realizing the automation and standardization of sample pretreatment, and effectively improving the accuracy and efficiency of testing. Currently, the grinding and extraction processes for food testing samples are separate, requiring manual transfer of samples between the grinding and extraction equipment. This is not only cumbersome and time-consuming, but also makes it difficult to achieve high-throughput processing. In addition, the open transfer process increases the chance of samples being exposed to the environment, which can easily lead to contamination or sample loss due to adhesion to the container walls, affecting the accuracy of the test. Therefore, an automatic grinding and extraction machine for food testing samples is proposed. Utility Model Content

When motor 6 starts, it drives the rotating shaft 18 to rotate at high speed, so that multiple sets of crushing rods 19 and grinding discs 28 fixed on the rotating shaft 18 move at high speed, shearing, impacting and grinding the sample in the grinding chamber 17. The crushing rods 19 with a quadrilateral cross section can generate stronger turbulence, and work together with the grinding discs 28 to crush the sample into a homogeneous powder state in a short time and make it fully mixed with the extraction solvent. After grinding and extraction are completed, motor 29 starts and drives grinding chamber 17 to rotate via connecting shaft, so that guide shell 20 rotates to be flush with opening 23. Electric telescopic rod 21 retracts and pulls arc baffle 22 to slide in the sliding port of guide shell 20, opening the feed port of grinding chamber 17. Electric telescopic rod 12 starts and pulls sealing plate 14 upward via connecting strip 13, opening the sealing port of filter shell 2. The solid-liquid mixture in grinding chamber 17 flows into filter shell 2 below through opening 23 under the action of gravity. When the electric telescopic rod 12 is activated, it pulls the sealing plate 14 together through the connecting strip 13 to close the sealing port of the filter shell 2. At the same time, the micro booster pump 25 is activated, generating a slight positive pressure. The solid-liquid mixture is extracted through the filter screen 27 through the booster pipe 26. The extract is smoothly pushed into the collection shell 8 below by the discharge hopper 30, completing the automatic collection of the sample.
