Problems solved by technology
The extraction solution concentration in the above-mentioned aquatic product extract treatment process adopts the method of blowing air or nitrogen to concentrate, and its concentration efficiency is low
On the other hand, when filtering the extract liquid through the filter membrane, only one sample of the extract liquid can be filtered in one treatment process, which leads to a large amount of time spent on the processing of large batches of samples in actual detection. Relatively cumbersome, time-consuming and labor-intensive

The invention discloses efficient liquid sample treatment equipment and aims to provide efficient liquid sample treatment equipment which is convenient to operate, high in concentration efficiency and capable of concentrating multiple extracting solution samples simultaneously. The equipment comprises a nitrogen concentration mechanism, wherein the nitrogen concentration mechanism comprises a vertical guide rod, a guide sleeve glidingly arranged on the vertical guide rod, a support plate arranged on the guide sleeve and a heating water tank with an open upper end, a limit plate is arranged on the upper end surface of the heating water tank and provided with multiple vertical limit through holes, and multiple vertical nitrogen spray pipes in one-to-one correspondence with the vertical limit through holes are arranged on the support plate.
Description
technical field [0001] The invention relates to a pre-treatment device for aquatic products, in particular to a high-efficiency treatment device for liquid samples of aquatic product extracts. Background technique [0002] With the improvement of people's living standards, while the production and consumption of aquatic products have greatly increased, the quality of aquatic products has also attracted more and more attention. How to test the quality of aquatic products is a problem that consumers are very concerned about. According to relevant food regulations and food inspection requirements, aquatic products need to pass sensory inspection, physical inspection, chemical inspection and other tests to ensure the quality and safety of aquatic products. [0003] At present, one of the processing procedures of the extract used for aquatic product testing includes the following steps: first, the extract is concentrated by a nitrogen concentrator, that is, air or nitrogen is blo...
