THE SURFACE-GLAZED PELLETS TECHNOLOGY USING IS GUARANTEE EFFECTIVE PELLETS MANUFACTURE
The technology for the production of high-quality surface-glazed pellets from biomass certified according to European standards developing purpose is the design and implementation of modern technological equipment on its base. The developed technology should take into account the specific physical, chemical and rheological properties of raw materials and according to them determine the preparation method, destruction and compression of finished products. The scientific and technical justification of such technology will enable to build in practice a profitable pellet production that will work efficiently. During the development of the surface-glazed pellets production technology, this method was used to change the structure of wood and other types of biomass, which using allows the thermoplastic biopolymers transition from solid elastic-visco-plastic condition to a glazed. These transformations are realized in wood under the influence of a complex of physical factors (temperature and pressure) under conditions of certain humidity. The main result of developed technology using is its successful application in the design and operating modes in the production line of surface-glazed pellets based on the CK-3 drying complex. Conclusions. The first proposed line for surface-glazed pellets production on the basis of the CK-3 drying complex has the following main advantages in comparison to traditional equipment ABM-1,5: 1) consumes 10% less raw material per year (800 tons of biomass, or $ 15 thousand of raw materials); 2) for recycling 1 ton of biomass consumes 100 kW less of electricity, which corresponds to saving 600 MW * h or $ 35 thousand per year; 3) For granulation 1 ton of raw material per hour CK-3 uses one granulator OGM-1,5, and for ABM-1,5 two such granulators are necessary; 4) the CK-3 using allows the production of EN1plus class pellets.
