DRYING OF THE MICROSPHERE FOR THE MANUFACTURE OF HEAT-INSULATING DRY BUILDING MIXES

A promising area for the production of heat-insulating dry building mixes is the use of the microsphere of thermal power plants, that will promote the formation of thermal insulation, strength, chemically and thermally stable properties of products. To dry the microsphere, a filtration method was proposed which consists in filtering the heat agent through the porous structure of the material in the direction "material - perforated grate".

Heat Transfer Process During Filtration Drying of Grinded Sunflower Biomass

Filtration drying of grinded sunflower stems as the unit operation of the technological line for solid biofuel production has been proposed. Theoretical aspects of heat transfer processes during filtration drying have been analyzed. The effect of the drying agent velocity increase from 0.68 to 2.05 m/s on the heat transfer intensity has been established. The values of heat transfer coefficients have been calculated on the basis of the thin-layer experimental data and equation .

Рroduction of light fillers on the basis of technogenic raw materials

In Ukraine, along with the growing demand for tonnage production of light fillers, the need for raw materials is growing, considering that most of the range of light fillers is made from natural raw materials. Thus, a promising direction of utilization of TPP slags and coal concentrate obtained by enrichment of primary coal sludge is there involvement to the production process after preliminary drying.

Hydrodynamics of Cotton Filtration Drying

The work deals with the results of using the cotton fiber as the purest and most natural cellulose, as well as a raw material for the production of various chemical products. The necessity of cotton fiber preparation for its use in the chemical industry and expediency of its drying via a filtration method has been substantiated. The geometrical parameters of individual cotton villi, physical and mechanical characteristics of the layer were experimentally investigated.

Effective techniques for bio-coal briquettes production.

The production of bio-coal briquettes gives an opportunity to utilize low grade coal as well as the great amount of agricultural residues, to increase the calorific value of obtained briquettes and to improve their chemical and physical properties. The present study is focused on developing the technological scheme which gives an opportunity to reduce the energy consumption in production line of composite fuel as well as to produce bio-coal briquettes with good mechanical integrity.

Modeling of internal diffusion mass transfer during filtration drying of capillary-porous material

The article presents the results of theoretical and experimental studies on the determination of the coefficients of internal diffusion of moisture from capillary-porous materials of plant origin during filtration drying, in particular, beet pulp, a by-product of sugar production.  A model based on the solution of the internal diffusion differential equation with the corresponding initial and boundary conditions were used to find the internal diffusion coefficient. 

Activation energy and effective moisture diffusivity determination in drying of grinded artichoke stems

In Ukraine plant biomass from crop fields and forests is the dominant renewable energy source and it is suitable to replace fuels by producing bio-gas, bio-ethanol as well as solid bio-fuel. Tubes of Jerusalem artichoke are used as functional food ingredients such as inulin, fructose and oligofructose as well as bioactive ingredient sources for pharmaceutical and cosmetic applications.
