Description

technical field [0001] The invention relates to a detection device, in particular to a device for testing friction and wear between food machinery parts and processed food. Background technique [0002] In the process of food processing, the contact surface of food machinery and food materials is often accompanied by friction and wear. For example, during the process of grain husking, there is extrusion and friction between the mechanical surface of the grain and the grain particles, and there is extrusion and friction between the grinding disc of the refiner and the abrasive, and the mechanical surface after friction and wear will have a negative impact on the processing performance of the food machinery. Significant effects, especially that worn surfaces are more prone to bacterial adhesion, may also have a significant impact on food safety. Therefore, it is very important to study the friction and wear between food machinery and processed food. However, most of the exis...

Problems solved by technology

However, most of the existing friction and wear testing machines under laboratory conditions are standard material testing machines, which can only test samples of standard sizes and shapes, and food has its own unique characteristics, such as individual differences in soybeans and rice. Larger, using a single soybean or rice for the test is not only difficult to clamp and fix, but also has poor representation, and it is difficult to simulate the actual friction and wear between food machinery parts and processed food

However, using a small mechanical device close to the actual food machinery to simulate and test the wear between the food machinery parts and the processed food can well reflect the actual wear conditions, but it is difficult to detect and test the food machinery parts in different wear stages. It is also difficult to realize the precise control of various performance index parameters in the whole process of friction and wear.
