Description

Technical Field

[0001] The utility model belongs to the technical field of extraction and liquid separation, and particularly relates to an extraction and liquid separation device. Background Art

[0002] In the process of food testing, in order to detect whether the nutrients or harmful substances in the food meet the standards, the food often needs to be processed during the food testing process. The most common processing method is to extract the food and detect the content of nutrients or harmful substances in the food by extraction, such as meat products.

[0003] Extraction is an important step in food testing. It is a method of dissolving nutrients or harmful substances in food into organic solvents by using differences in solubility. During the extraction process, in order to meet the testing requirements, the amount of food added is relatively large. Therefore, in order to make the extraction easier, the food needs to be crushed in advance and added to the extraction device after being crushed into pieces.

[0004] However, during the extraction process, especially when the amount of material is relatively large, a large amount of material settles at the bottom of the device, which is not only difficult to stir, but also difficult for the organic solvent to fully react with the material. Therefore, in the actual working process, when it is difficult to stir, the material can only be soaked in an organic solvent until it is softened before extraction can be carried out.

[0005] Obviously, this method takes a long time and relies entirely on static immersion to soften the material to a state that is easy to stir and extract, which cannot meet the detection needs.

[0006] Therefore, in the actual working process, the operator can only process the material by adding an extraction device, but this method also has major defects, such as adding processing steps. After extraction, the extracts in multiple extraction devices need to be merged. During the merging process, the material is easily lost during transportation through the pipeline, etc. Utility Model Content
