Description

Technical Field

[0001] The utility model belongs to the technical fields of seed science and food science, and relates to a single-grain grinding device for wheat, which is mainly applicable to the grinding of single seeds / grains of crops such as wheat and related work. Background Technique

[0002] The seeds of seed plants develop from fertilized ovules. All seeds contain embryos, and most seeds have a significantly characteristic seed coat, while there are obvious interspecific differences in the retention degrees of endosperm and perisperm. Some seed coats only exist in a basic form, and the main structure on the periphery is the pericarp. The pericarp develops from the ovary wall, so the dissemination carriers of such plants (such as wheat) are not strictly seeds in the botanical sense, but fruits.

[0003] Wheat ( Triticum aestivum L.) is one of the three major cereals in the world. Wheat fruits can be used both as seeds (propagules, with high vitality) and as food. The former belongs to the field of seed science, and the latter belongs to the field of food science; the grinding and sample preparation process is involved in both seed science and food science research.

[0004] Case: Taking Fusarium head blight as an example, Fusarium head blight is an important disease in global wheat production, mainly caused by Fusarium graminearum ). The occurrence of Fusarium head blight in wheat not only causes large-scale production reduction, but the wheat grains or seeds infected with Fusarium head blight will also accumulate vomitoxin (deoxynivalenol, DON); from the perspective of seed science, the decline in the health of infected seeds will directly affect seed vigor and even lose the value for seeding; from the perspective of food science, infected grains will seriously threaten food safety and human health, so it is very important to determine the DON content in wheat.

[0005] At present, the detection methods for the DON content in DON-contaminated wheat mainly include detection methods relying on chromatography or mass spectrometry technology and immunoassay methods using specific recognition of antigen and antibody. The traditional detection and sample preparation method (reference: "Determination of deoxynivalenol in foods - Immunoaffinity chromatography purification high performance liquid chromatography method (GB / T 23503-2009)") is as follows: Take a sufficient amount of sample, grind the sample, and grind hard grains and the like with a high-speed universal grinder. The determination of the DON content in single wheat seeds / grains has the characteristics of high efficiency, accuracy, economy, and avoiding cross-contamination, but there are few relevant reports, especially the lack of a single-grain grinding device for wheat. Although there are some sample crushers on the market, by adding liquid nitrogen and putting steel balls to vibrate at high speed to break the sample, they are mainly used for some easily broken plant tissues such as leaves, and the effect of grinding single seeds / grains is poor, and problems such as tube explosion are likely to occur. Therefore, in order to meet the actual needs of detecting the DON content in single wheat grains and obtain accurate determination results, it is very important to continuously innovate and improve related equipment and devices.

[0006] In response to the actual requirements of single-grain grinding of wheat, a simple and practical single-grain grinding device for wheat has been developed. This device has the advantages of simple structure, convenient operation, high working efficiency, accurate measurement results, wide application range, etc., and has good practicability, which has important practical significance for related work such as wheat seed quality evaluation, grain processing, scientific research, and teaching.
