“…In a work by Vasiliev et al, the effect of the logs' collision with internal parts of the barking drum and between each other on the process simulation was ignored. Considering the logs as spherical bodies, they were shown to affect the group debarking process in terms of quality and duration [13].…”

The process of wood debarking plays a crucial role in determining the price and quality of the final product. Hence, this work aims to elaborate on a theoretical basis for upgrading wood chips production technology. Consideration should be given to the influence of various debarking parameters when processing wood in barking drums. Such parameters as the number of wood collisions with each other and against a drum body, shear pressure, and others were chosen as equation coefficients to model the wood debarking time and knife sharpening angle. The treatment time is shown to depend on the number of collisions, the diameter of the log and indices that consider filling, the proportion of bark and the thickness, and wood hardness. It was established that the time required to debark the tree using knives is 1.5-3 times lower depending on the temperature of raw materials. Moreover, the process tends to be intensified with increasing knife sharpness.

“…Many compatriots were partly engaged in the study of this process. According to Vasilev et al [13], this process is divided into several areas when logs are pushed against one another or when they contact the internal structures. Other authors have engaged in modeling this process.…”

In recent years, the results of intellectual activity - numerous technological and technical solutions - have been patented for the basic operations of the forestry complex. Insufficient attention is paid to the formation of knowledge bases in the field of technologies and equipment for involving non-timber forest resources in the processing. The formation of databases in this area is caused by the identified trends in the development of products from various types of natural raw materials for the pharmaceutical, food, cosmetic industries and other spheres of the social sphere and the economy. Among the types of natural raw materials, an important place is occupied by raw materials with a wide range of biological effects, including woody greens. The development of a knowledge base in the field of involving tree greenery in various spheres of the social sphere and economy was carried out on the basis of a systematic patent search. The analysis made it possible to form a knowledge base about the main most characteristic technological and technical solutions patented in Russia in the field of harvesting, processing and use of greenery of tree species growing in Russia in industry, agriculture and in the social sphere. These solutions are classified according to the types of greenery used (complex of conifers, and in the context of woody greenery of fir, pine, larch, cedar and dwarf cedar, juniper, and deciduous trees). Within each class of patents in the field of wood greenery processing, patents are given taking into account the directions of their use, the effects achieved as a result of the implementation of patented solutions with the allocation of economic entities conducting patenting in the studied area. In this regard, the authors carried out research with the conduct of patent information search, collection and systematization of information. The state and tendencies of directions of patenting in the field of technologies and equipment for the use of tree greenery in industry and in the social sphere are revealed, the main goals of patenting (effects) are determined to achieve which the patented intellectual property objects are considered. The most interesting patents collected during the formation of the knowledge base are presented.

In the context of more intensive use of forest biomass, efforts to combat global climate change, the desire for more rational use of wood and an increase in surplus value in wood products, it can be assumed that primary woodworking processes require optimization. The aim of this work is the creation and experimental verification of a mathematical model of rational debarking of a log. The proposed mathematical model is based on a semi-empirical theory of fracture mechanics, the conclusions of which the authors optimize for the task of separating bark from wood during industrial debarking. During the experiments, a specially created installation was used. The results of experimental studies showed good quantitative and qualitative coincidences with the study results of the developed mathematical model. Thus, the developed model allows evaluating, at the stage of theoretical research, one of the main parameters of group debarking of timber. Namely, the time of timber processing taking into account the structural elements of the drum, parameters of pulpwood, their properties and temperature.
