Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine texture testing technology, and in particular to a traditional Chinese medicine texture testing component for use in a texture analyzer. Background Technology

[0002] Texture analyzers, as precision instruments capable of objectively and accurately describing the physical properties of samples, are playing an increasingly important role in the field of texture testing of traditional Chinese medicine (TCM). They mainly consist of key components such as a main unit, probes, sensors, data processors, and software. By simulating the human oral process of chewing food, they perform texture analysis on TCM samples, including the quantitative determination of parameters such as hardness, elasticity, and adhesion. This technology provides a scientific basis for process control and quality improvement in TCM manufacturing, and also offers new ideas and methods for texture evaluation of TCM.

[0003] The working principle of a texture analyzer is based on the testing of mechanical properties. By setting different test modes (such as compression, puncture, shear, and tension) and probe types (such as disc, cylinder, and single-blade probes), stress tests are performed on the traditional Chinese medicine sample. The sensor converts the motion state and stress conditions of the probe into electrical signals, which are then transmitted to a data processor for analysis and processing, ultimately yielding the texture characteristic parameters of the traditional Chinese medicine.

[0004] Because traditional Chinese medicine (TCM) is a complex and vast system with diverse forms, traditionally used texture analyzers are insufficient for testing the physical properties of all TCMs. Therefore, it is necessary to design suitable components for testing the physical properties of TCMs based on their characteristics.

The pressure plate is vertically slidably connected inside the compression container.

[0009] The puncture property testing component includes a chassis and a probe. The chassis has a plurality of penetration grooves with different diameters. The probes are placed one by one with the penetration grooves according to their size.

A placement seat is used to hold the Chinese medicinal materials. Under the support of the placement seat, the Chinese medicinal materials are subjected to the compression of the bending indenter and undergo bending deformation.

[0027] The compressibility test component includes a pressure plate 4 and a compression container 5. A connecting column is fixedly connected to the top surface of the pressure plate 4, and a connecting screw is installed on the top of the connecting column. The pressure plate 4 is vertically slidably connected inside the compression container 5.

[0028] The puncture property testing component includes a chassis 7 and a probe 6. The top surface of the chassis 7 is provided with a plurality of penetration grooves. The apertures of the plurality of placement grooves are not equal. The plurality of probes 6 are respectively placed in a corresponding manner to the penetration grooves.

[0029] Among them, the three-point bending probe 1, the pressure plate 4, and the probe 6 are respectively equipped with force sensors, and the force sensors are connected to the controller.

[0030] When using this invention, to test the bending properties of Chinese medicinal materials, a three-point bending probe 1 is connected to a texture analyzer to apply a downward load. A three-point bending support beam is used to place Chinese medicinal materials of different sizes. Under the support force of the three-point bending support beam, the Chinese medicinal materials are subjected to the compression of the three-point bending probe 1 and undergo bending deformation.

A compression container 5 is used to hold the Chinese medicinal materials. The Chinese medicinal materials undergo compression deformation under the pressure applied by the pressure plate 4 and the support force provided by the bottom of the compression container 5. The displacement of the pressure plate 4 is controlled, and the force required for the Chinese medicinal materials to reach a certain degree of compression characterizes its texture. When testing the puncture properties of the medicinal materials, probes 6 are connected to the texture analyzer to apply a downward load. The placement groove on the base 7 is used to place the Chinese medicinal materials. The Chinese medicinal materials are penetrated under the local load applied by the probes 6, and the hardness exhibited is used to characterize the texture of the Chinese medicinal materials.

[0031] The scheme is further optimized. Several sets of guide bars are fixedly connected at equal intervals around the circumference of the compression container 5. The guide bars are vertically set on the inner wall of the compression container 5. Several positioning grooves are opened at equal intervals around the circumference of the outer wall of the pressure plate 4. The positioning grooves are set one-to-one with the guide bars, and the guide bars are slidably connected in the positioning grooves.

[0032] The design was further optimized, with the pressure plate 4 having a radius of 18mm and a thickness of 3mm; the connecting column having a radius of 6mm and a height of 9.5mm.

[0033] Further optimization of the design resulted in the following: the inner diameter of the compression container 5 is 40mm, the outer diameter is 44mm, the wall thickness is 2mm, the internal height is 40mm, and the external height is 43mm.
