Thermodynamic approach in the theory of drying

S.A. Podgorny, E.P. Koshevoy, V.S. Kosachev

Considered thermodynamic approach to the description of drying kinetics. The key notion in using thermodynamic methods of analysing moisture transfer during drying and conditioning is the notion of potential. Here the dynamic function of the system state is understood, which is the same in all points of the system and during nonequilibrium state there is a gradient which determines the direction and the speed of transfer in a particular substance. Thermodynamic method of studying the processes of substance heat and mass transfer is based on law of energy conservation and conversion and the law of conservation of substance mass. Particularly important in this method is defining transfer potential which as a rule equals the partial derivative of the correspondingly chosen characteristic function by generalized coordinate. Depending on how the system interacts with the environment, the characteristic function could be internal energy U, enthalpy H, free energy F and Gibbs function Z. Mass transfer is caused by chemical potential which could be defined by taking respective partial derivatives from characteristic functions. There are several approaches to defining a chemical potential of moisture transfer of capillary-porous objects. The article proves that a simple but still as accurate as other approaches is the method of defining potential transfer introduced by L.M. Nikitina which is based on the thesis proved by her that the moisture binding energy is numerically equal to the potential absolute value which enables us to base calculations upon the experimental data on hygroscopic properties of particular materials. It was found with the help of splines that in the practically important for drying range of moisture, the dependence between the experimental potential and moisture content in untreated rice grain has a linear character.

Ways to reduce injury to corn in process of transport and post-harvest treatment

E.V. Soloveva, I.V. Shipilin

We were studied the properties of corn as an object of transport and post-harvest treatment. We were analyzed the impact of the working bodies of machines and mechanisms on the integrity of the individual grains. We were considered the role of the broken and injured grain in a pile on the general condition of the grain mass. Also we were studied morphological characteristics of corn and differences in the hygroscopic properties of its germ and endosperm. As a result of the research, we were followed conclusions: the injury of corn occurs both at harvest and during transport and processing of grain; increased susceptibility to moisture absorption of the germ of corn affects the quality of the grain mass in the presence of her broken and injured grain. Thus, the number of grain from mechanical damage in the pile should be minimized by optimizing the processes of transport and post-harvest treatment, as well as through research of new materials and their use for the manufacture of the working bodies of technological machines and mechanisms.

Keywords: corn grain, injury to grain, transportation of grain, hygroscopicity of grain.

Estimaition parameters of kinetics of rice grain drying process using mass transfer potential

S.A. Podgorny, E.P. Koshevoy, V.S. Kosachev

Mass transfer potentials agree with the thermodynamic scale of mass transfer drying force and this is what creates essential advantages for representing the process of drying when the material being dried and the drying agent interact. Considering the established connection between a design potential and an experimental potential, parameters of the diffusion rate equation were identified for the problem of time-varying transfer of the experimental potential from the particle being dried through the mass transfer by the experimental data. A primary correlation analysis of the experimental data revealed a connection between drying parameters and kinetic coefficients of the equation. Kinetic dependences were grouped with regard to the most significant parameters of the drying process: the temperature and the speed of the drying agent. An important connection between the temperature and the speed of the drying agent has been discovered with the kinetic coefficient l1. To determine the effect of drying parameters on this coefficient, we implemented a multi-level plan of the second order in relation to drying parameters under study. For the numerical evaluation of the regression model, Excel utility “regression” was used, which allowed both to calculate coefficients of the regressive model and to get a statistical estimation of their significance. Considering a physical meaning of the kinetic coefficient l1 in the rice drying equation, the calculations were made to estimate the diffusion coefficient D. The study which was carried out enabled us to reveal a connection between drying parameters and kinetic coefficients of the diffusion equation for the problem of time-varying transfer of the experimental potential from the rice grain being dried. The analysis of the obtained data enabled us to get significant coefficients of the regression model which cause changes of the kinetic coefficient l1 and diffusion coefficient D.

O.N. Sheludko, N.K. Strizhov, A.M. Shnarevich

To determine the parameters of quality of the red wines studied mass concentration of the coloring substances (anthocyanins) by analyzing the absorption spectrum of grape must. The composition of anthocyanins depends on the grape variety and soil-climatic conditions of its growth. A variety of color of anthocyanins is due to the peculiarities of their structure and formation of complexes with metals. When exposure time of wine the content of anthocyanins is reduced as a result of their polymerization and precipitation. The content of anthocyanins in red wines is 30–500 mg/dm3. The spectra obtained dependence of the optical density of grape must from the wavelength of the incident light and the exposure time of the juice in the pulp. It is shown that the time for complete extraction of coloring components from grape skin in the must is 10 h. The method of mathematical analysis of the absorption spectrum of which showed the presence in the must four coloring components, provided their calculated spectra are shown.

Keywords: grape juice, red wine, absorption spectra of coloring components, mathematical analysis of spectra.

Studies show that the standard mode of cigarettes smoking method ISO does not fully correspond to the real manner of smoking smokers and does not give reliable information about the quantity consumed as result of smoking toxic substances – tar and nicotine. Studies conducted in VNIITTI the connection between the amount of nicotine contained in the cigarette ends with quantities of nicotine and tar in the main stream of tobacco smoke is established. On this basis developed methodology reliable estimates of toxicity actually inhaled by the smoker smoke, presented in the work. To participate in the research of cigarettes smoking were involved in 53 smokers – men and women of different ages and with different years of smoking. In the experiment consisted of 24 cigarettes brands which had a different format, design, different contents of nicotine and tar in tobacco smoke. Preliminary conducted cigarettes smoking each cigarettes brand on smoking machine in different modes according to the method ISO. It is established that the method of spectrophotometric analysis based on the measurement of optical density of extract of cigarette ends gives more stable results in the content of toxic components in the smoke than gas chromatographic analysis. The results analysis indicates that the data on tar and nicotine in the smoke obtained by cigarettes smoking individual smokers significantly higher than the data determined by standard methods ISO. The regression equations are derived with fairly high degree of reliability which express the dependence of the exceeding extent the results shown individual smokers when cigarettes smoking on the data obtained by standard method ISO.

Keywords: indirect measurement of toxic components of tobacco smoke, gas chromatographic analysis, spectrophotometric analysis, actually consumed amount of tar and nicotine.
