Experimental research of the process of shock pulse transformation through biological objects of fixed geometric shape

Successful implementation of agricultural products requires compliance with the requirements of standards to ensure its high quality, ensuring the technological process (production, processing, storage) with a sufficient level of quality characteristics of the initial raw materials, product quality control at intermediate and final operations. Such qualitative characteristics of products, particularly a fixed geometric shape, the degree of ripeness, presence and depth of the damage, it is not always possible to determine the external condition of the product (e.g., melons) without its destruction. To assess the qualitative and quantitative characteristics of agricultural products, various physical methods are used, of which a special place is occupied by the method of acoustic sensing, which consists in the fact that the properties of products (as biological objects) that determine the excitation and propagation of elastic vibrations are closely related to their anatomical structure and physical and biochemical characteristics, which in turn change during their vegetation when reaching the appropriate degree of ripeness. This material presents the results of experimental studies to establish the relationship between the parameters of the aftereffect of shock excitation of biological objects of plant origin of a fixed geometric shape with their qualitative characteristics, to determine the characteristics and their quantitative values, which in turn makes it possible to implement technical devices Express nondestructive control of qualitative characteristics of agricultural products.
