The ways of improving the work of food enterprises during processing of agricultural raw materials on the basis of a system analysis of the durations of technological operations are considered. The basic mathematical models of technological processes have been analyzed and the possibility of using unified technological operations to predict the time of completion of work has been shown for processing various pairs of raw materials. It is established that the construction of mathematical models of technological processes of processing of agricultural raw materials should be based on using the potential of transfer of the target component between isopotential surfaces. This allows not only to unify the created models of technological processes, but also to significantly increase their extrapolating ability to estimate the durations of technological operations
A mathematical description of the potentials of mass-transfer of hygroscopic materials is possible on the basis of analytical expressions describing sorption and desorption isotherms. Because of the complex nature of the interaction of colloidal capillary-porous materials with moisture, determined by the action other than sorption forces (physical sorption, absorption, chemisorption), capillary condensation forces and osmotic forces, which for different materials are specific and quantitatively different, to date There is no single universal dependence for the analytical description of isotherms of sorption and desorption. Accordingly, there is a wide variety of analytical expressions for the description of isotherms of sorption and desorption. There are many different methods of analytical description of the sorption properties of colloidal capillary-porous materials. All known methods can be divided into two groups: the first should include analytical expressions derived theoretically on the basis of various hypotheses and assumptions, while the second - purely empirical based on the expansion or change in the forms of models of the first group. A large number of equations of equilibrium isotherms are mathematically equivalent. Thus, the method of determining the transport potential based on position allows us to take as a basis for calculation the experimental data on the hygroscopic properties of certain materials and to use the phenomenological approach for the engineering calculation of complex technical devices
The article studies the influence of polymeric in
the form of formers and growth regulators on the
growth and development of rice plants when
grown in saline conditions. We controlled the effect
of salinity on grows regulators and vigor, seed
germination, root and shoot weight, the content of
photosynthetic pigments parameters, induction
curves of delayed fluorescence, the indicators of
structure of harvest, grain yield. It was found, that
pre-sowing seed soaking in solutions of polymer
grows regulators has a stimulating effect on the
growth and development of rice plants in the early
stages: we significantly increased germination and
emergence, dry weight of root and shoot compared
to control. At different stages of ontogeny
rice, the absolute content of pigments in the leaves
and the relationship between the individual variants
change. The absolute content of pigments in
leaves and their relationship between experiences
at different stages of ontogeny change. In the period
of intensive vegetative growth from seedling
stage the content of total chlorophyll is maximum,
and by the end of the growing season it decreases.
It can be assumed that the salinity of the substrate
significantly reduces the productivity of photosynthesis
in young plants, possibly due to imbalance
of ions in the cell, the older it gets – the weaker
the phenomenon is and even becomes reversed.
The second maximum IR ZF increases during the
growing season from germination to flowering,
then decreases to the beginning of ripening in all
embodiments. The same dynamics is characteristic
of the magnitude of the proton gradient in the
membranes of chloroplasts tylakoids. Salt protection
effect of growth regulators on grain yield is
significant on both backgrounds of mineral nutrition
The article studies the impact of waste and ash from the elevators of their burning on the microflora of rhizoplane, rhizosphere and phylloplane of winter wheat grown on leached black soil
The article is devoted to the investigation of the influence of applying elevators waste to the soil on the content of ions Ca2+, K+, NH4+ , NO3 - and photosynthetic pigments in leaves of plants of winter wheat in the cultivation of the leached black soil
The article investigates the impact of waste of elevators on morphological parameters and productivity of winter wheat grown on black leached soil
The equations for evaluation of the stationary state of lactic acid microbiological synthesis have been received. The kinetic dependencies for specific biomass growth rate, consumption of the substrate are given. The particular qualities of growth of homofermentative lactic acid producer Lactococcus lactis CH5 depending on the composition nutrient medium: glucose and yeast autolysate concentration are examined. The influence of the method of cultivation on the productivity and the speed of the lactis acid synthesis are analyzed
