| Popis: | 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 fir-needles includes such operations as the collection of green verdure, the separation of the fir-needles from the branches, and grinding of it. Currently about 3-4% of potential fir-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 fir-needles. The most difficult 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 final product. Development of technology for processing fir-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-finished product of the required fractional composition and to preserve all the useful substances. |
