Abstract
Relaxation processes occur in bulk grain raw materials (wheat, corn, etc.) under mechanical influence. At the same time, the plastic properties of the material increase, which leads to a reduction in the load and energy spent on processing the product.
In practice, most of the stress decreases in a relatively short period of time (about 30 seconds), so the 1st stage of relaxation is important. Then, after a certain time, the grain was pressed again until it collapsed (point B).
As can be seen, the tensile strength of the test material in this case is less than the tensile strength achieved without taking into account the relaxation process. As a result, during the relaxation process, the strength of the grain product decreases.
The aim of the study is to study the relaxation properties of grain raw materials under mechanical influence. The calculations carried out showed that taking into account relaxation processes allows reducing the energy spent on the destruction of grain products by 20 to 30%.
The article presents the results of studies of stress relaxation of wheat grain, which are necessary for the calculation and design of highly efficient technological equipment for grinding and tableting a product based on grain raw materials.
