Description

Technical Field

[0001] The utility model relates to the technical field of plant protein detection, in particular to a sample processing device for determining plant protein using an organic solvent method. Background Art

[0002] The solvent method is also called the co-precipitation method. The drug and the carrier material are dissolved in an organic solvent. After the organic solvent is evaporated, the drug and the carrier material are precipitated at the same time to obtain a co-precipitate formed by the mixture of the drug and the carrier material. The co-precipitate is obtained by drying. Commonly used organic solvents include chloroform, anhydrous ethanol, 95% ethanol, acetone, etc. The advantage of this method is that it avoids high heat and is suitable for heat-unstable or volatile drugs. Carrier materials that are soluble in water or a variety of organic solvents, have high melting points, and are unstable to heat can be selected, such as PVP, galactose, mannose, bile acid, etc. PVP is easy to decompose when melted, and the solvent method is better, but the amount of organic solvent used is large, the cost is high, and sometimes the organic solvent is difficult to completely remove. In addition to being harmful to the human body, the residual organic solvent is also easy to cause drug recrystallization and reduce the dispersion of the drug.

[0003] The organic solvent method is used when measuring plant protein. Before the measurement, a grinding device is used to grind the plant sample to facilitate mixing and extraction with an organic solution.

[0004] Prior art includes a utility model with publication number CN216678522U. The utility model discloses a plant grinding device, comprising a mortar and a grinding rod that cooperate with each other, wherein the grinding rod comprises an operating rod and a grinding body; the grinding body is a circular structure with arc protrusions at both the upper and lower ends, and one end of the operating rod is connected to the top of the upper protrusion of the circular structure. Compared with the existing spherical grinding end, the grinding body of the utility model has an increased contact area with the plant during grinding, which can not only reduce the grinding time, but also avoid the problem that individual roots, stems, leaves or fruits cannot be ground. At the same time, the grinding body is a circular structure with arc protrusions on the upper and lower ends. Compared with the grinding end with a planar structure, it can reduce the scum attached to the grinding body to a certain extent, and solve the problem that the head (grinding end) of the grinding rod prepared in the grinding device is not coarse but too thin, making the grinding process very unsmooth, that is, the head of the grinding rod has a smaller contact area with the plant to be ground, resulting in that the grinding end is not easy to hit the roots, stems, leaves or fruits, so that individual roots, stems, leaves or fruits cannot be ground and the required grinding time is long.

[0005] The inventors found in their daily work that when processing samples used for the existing organic solvent method for determining plant protein, most of the samples are manually ground, which leads to inconvenient operation and low efficiency. At the same time, some other grinding equipment does not have a filtering effect during grinding, resulting in the use of unqualified samples, which makes the sample unable to fully react with the solution, resulting in poor extraction effect and inaccurate measurement.
