Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a plant tissue sample extraction device for food testing. Background Art

[0002] During the testing of food plants, an extraction device is required to extract the roots, stems, and leaves of natural plants so that the active ingredients in the roots, stems, and leaves of herbal plants are dissolved in the solution, thereby achieving the extraction of active components.

[0003] The initial extraction requires crushing, stirring, and filtering once to obtain a solution without large impurities. The current initial extraction is done manually, requiring the use of a crushing mixer, manual introduction of an appropriate amount of solution, and then pouring the liquid in the crushing mixer into a filter device for filtration. Multiple machines are required. In this process, there will be problems such as the large amount of space occupied by the machine, resulting in a cluttered laboratory table, confusion in the operation sequence, and easy spillage of the solution.

[0004] To this end, we propose a plant tissue sample extraction device for food testing to solve the existing problems. Utility Model Content
