Technology of processing of green verdure of conifers in the wood cutting area

Abstract

Green verdure of conifers having a rich reserve of biologically active substances such as essential oils, vitamins, carotene, carbohydrates, trace elements, and proteins is a valuable raw material for wood-chemical production. The technology for the manufacture of any kind of products from the fi r-needles includes such operations as the collection of green verdure, the separation of the fi r-needles from the branches, and grinding of it. Currently about 3-4% of potential fi r-needles resources are used which is due to the lack of processing technologies for this type of raw material in the wood cutting area. An analysis of existing technologies for preparing and processing green verdure of conifers has shown that they all involve the export of softwood knots and branches to the consumers of this type of raw material, which entails not only transport losses, but also a reduction in the qualitative indicators of the fi r-needles. The most diffi cult and hard operation mechanization in the process of harvesting green verdure is the separation from the woody parts of the branch. It basically determines the quality of the fi nal product. Development of technology for processing fi r-needles in the cutting area requires the use of a new mobile unit. The design of the proposed unit allows performing the operations of separating and grinding the green verdure of conifers, and further packaging of the product while the unit itself is able to move around the territory of the cutting area. It will allow to make coniferous semi-fi nished product of the required fractional composition and to preserve all the useful substances.

Modeling a brush separator for forage woody greenery

“…At the same time, it is known that up to 40% of logging waste is woody greenery, rich in fodder and biologically active substances. Currently, about 3-4% of all coniferous woody greenery that is available for processing is used [2]. The main difficulty in using woody greenery is the costly transportation of felling residues.…”
