[0001] The utility model relates to the technical field of vegetable safety detection equipment, and particularly relates to a machine for preparing leafy vegetable samples. Background Technique
[0002] Vegetables are essential foods in people's lives. With the improvement of living standards, people pay more and more attention to the quality and safety of vegetables. Usually, vegetables are sampled and tested regularly. Vegetable pesticide detection mainly refers to the detection of pesticide residues in vegetables to ensure the safety of vegetables and compliance with food safety standards. The purpose of pesticide residue detection is to ensure that the pesticides used in the growth, transportation, and storage of vegetables do not pose a hazard to human health.
[0003] When detecting vegetables, they need to be crushed. Currently, the tissue grinders used in experiments include juicers, food processors, blenders, etc. Except for leafy vegetables, other types of vegetables have a high water content. After being processed, the samples become mud-like, which can meet the requirements of pesticide residue detection.
[0004] Disadvantages of existing tissue grinders (juicers, food processors, blenders): Only one set of cutter heads is used to crush the samples; leafy vegetables have a low water content and are light in weight. After the cutter heads of the machine rotate, the leafy vegetables stick to the wall and cannot be crushed, and samples in the form of vegetable mud cannot be prepared.
[0005] Therefore, we propose a machine for preparing leafy vegetable samples. Content of the Utility Model
