Optimization of processing branches, needles, and leaves (“woody greens”) of dark-coniferous breeds of thin tree stands using a modified plant

Abstract

The waste-free technological scheme is proposed in the paper. It is based on an installation which allows to optimize the integrated processing of woody greens (branches, needles, and leaves) from fir and spruce. This scheme takes into account their contribution to the mixtures made, as well as the age of plantations used to produce an essential oil and pine extract. An installation is designed with an internal and external condensation circuit of the vapor stream serving as the basis, the use of which increases yields and significantly reduces the time needed to release the water-soluble products being processed into coniferous extract.

Modeling a brush separator for forage woody greenery

“…As a fodder product, woody greenery are not a substitute for herbaceous fodder, but are indispensable as feed additives such as pine flour, fir oil, pine extract, chlorophyll-carotene paste. Moreover, the production of these products from woody greenery can be waste-free [5]. An unconventional use of coniferous woody greenery is also proposed, for example, the creation of an ecological heat-insulating material that is not inferior in characteristics to existing insulating materials made of wood [6].…”
