In the dairy industry, the segment of yoghurts and
yoghurt drinks is one of the most dynamically
developing. Competition contributes to the production
of high quality products. The transition to market
relations encourages producers to use new prescription
ingredients in the production of various yoghurts. In
addition, it is essential to improve the existing ones
and create qualitatively new technologies of products
with a directed change in the chemical composition.
Sour-milk drinks not only satisfy the physiological
needs of the body, but also have a preventive and
therapeutic purpose. Utilization of these products
contributes to the prevention of numerous diseases, as
well as life prolongation and increase of working
capacity. The dietary properties of sour-milk drinks are
determined by the presence of “live” beneficial
microflora and persist for a long time, as long as this
microflora remains viable and pure. The article
contains data distinguishing the effects of the use of
commercial fermentation starters EKOKOM Laktina,
TM GoodFood, Kaprina on the qualitative
characteristics of dairy clots. The article specifies the
influence of fermentation starters and vegetable fillers
on the organoleptic parameters of the final sour-milk
product. The authors of the article further present data describing the organoleptic and physicochemical
quality profile of yoghurt enriched with vegetable
fillers, obtained by introducing commercial
fermentation starters of various manufacturing
companies
Тhe article presents an investigation of hydrodynamic mixer for biodiesel production from vegetable oils hyperacidity in the conditions of agricultural companies. The process of hydrodynamic mixer which mixes the flow of biofuels from jatropha oil with carbon dioxide to wash it. The regularities of disclosing the relationship of the parameters (diameter and length of the mixing chamber), the mode (the pressure and flow rate) from the medium (dynamic viscosity, density, elasticity) to the energy characteristics of the process (mixing power on). Based on the method of similarity and dimensions of physical quantities obtained criterion turbulence. A reduction in the flow pressure and agitation power with increasing diameter. We have justified the mode (pressure at the nozzle exit corresponds to the critical), in which the carbon dioxide gets into the mixing chamber properties of liquids, solutions for biofuels, and the mixture becomes a quasi-homogeneous. Based criteria of regime change from a supersonic flow in the subsonic, allowed us to determine the condition of quasi-homogeneity of the mixture. It is proved that we form a supersonic flow liquid-gas at the same time it is transformed into subsonic, accompanied by the acoustic cavitation effect leap remixing due to isentropic pressure jump. The article justifies the physics of cavitation effects of carbon dioxide on biofuels, result of which is to improve the physical and chemical properties of the medium due to the structuring of the molecules of the solution, which has a positive effect on the mixing
Ozonization of incubation eggs when storing at an egg-storehouse is well included in technological process of production and egg sorting. Ozone influences absolutely all known viruses and microbes. Larger chickens are hatched from ozone-treated eggs, safety of chickens is increased. However, the present technology did not obtain the wide spreading in the sphere of poultry farming because of uneven concentration due to the volume of treated premises. In the result of mathematical modeling there was worked out the system of management with electrical and technological process of ozonization of egg-storehouses of poultry factories, indexes of quality the work of which was assessed in the system of automated projecting of logical-dynamic systems SimInTech. The summarized integral mean-square index (J = 9,7%) decreased on 19,3 % in comparison with the variant without regulation (J = 29%), that testifies on enough qualitative regulation of distribution of ozone concentration in an egg-storehouse and satisfies the shown acceptable value of the present index (no more 15%). On the basis of produced researches there was created the nomogram determining the tension of charging facility and discharge of a ventilator of electric ozonator in dependence on treated egg amount. In accordance with technical solutions there was worked out the principal electric circuit with system of electric equipment of electric technological process of ozonization of egg-storehouses of poultry factories on the basis of microcontroller ATmega8
The article presents the results of theoretical studies of
noise cutting circular sawing machines. Practical
calculation of the noise spectra is based on the
determination of the dependency of the sound pressure
of the noise sources of the object of study. In the sound
system, circular sawing machines sound energy is
emitted by the following sources: disc cutter and the
mandrel. Therefore, the dominant noise sources should
be allocated to the technological subsystem "tool –
mandrel” with a bit less rigidity than the carrier system
of the machine and directly receives the cutting forces
when milling. Thus, it is possible to reduce sound
pressure levels in almost two ways: by increasing
absorption production facilities and (or) decrease in
sound pressure of the noise source. In this work, we
have justified the second way – reduction of the
intensity of acoustic radiation of the source
In the article, a method of determining of initial ear motion velocity parameters after its separation from the stalk when stripping of grain crops with one-drum header is considered. The dependences of changes of normal and tangential component of ear’s velocity upon the parameters and operation regimes of the header and breadstand characteristics are illustrated
The results of the strength characteristics research for carp fish leather at different processing stages and the change of these characteristics during the process are presented. Possibility for the tensor equation the use is showed for the value both of the toughness and limited strains of fish leather with load direction
Fruits are an important part of the diet of humans and
many animals. In case of an improperly organized
process of storing of fruits, the loss of mass and
decrease of quality can be substantial. This makes
relevant the research, aimed at enhancing existing and
developing new technologies of fruits storing. In this
article, the results of the investigation of influence of
complex treatment of fruits with electromagnetic fields
of extremely low frequency (EMF ELF) and а biopreparation
on the change of microbial contamination
of their surface and on the loss of mass in the process
of long-term storage are revealed. Apples of the Idared
variety and pears of the Conference variety were the
objects of research. The change of microbial
contamination of the surface of fruits, undergone a few
types of pre-treatment (EMP ELF, bio-preparation
“Vitaplan”, complex treatment “EMP ELF + the biopreparation”
and no special treatment), after storing during 7 months in case of pears and 8 months in case
of apples is shown in the article. It was found, that the
greatest decrease of content of microorganisms on the
fruits’ surface is achieved as a result of the complex
treatment, combining the treatment with EMP ELF and
an aqueous solution of the “Vitaplan” bio-preparation.
The effective parameters of such a treatment for apples
and pears are represented
Technologies of fruits storing known at the present
time, solving actual problems – slowing down
biochemical processes, inhibiting ethylene synthesis,
do not provide fully the preservation of quality of
fruits due to not taking into consideration the
peculiarities of microflora of fruits and
microbiological processes, taking place during storage.
Purpose of the research: investigation of influence of
complex treatment of fruits with electromagnetic fields
of extremely low frequency (ELF EMF) and the biopreparation
“Vitaplan” on changing of losses of
biologically active substances in the process of longterm
storage. Objects of the research: apples of the
Idared variety and pears of the Conference variety,
regionalized in the Krasnodar region. Mass shares of
the vitamin C and P-active substances were measured in the process of storing. ELF EMF treatment was
conducted on an experimental installation. Fruits were
exposed to the action of electromagnetic fields with
specified parameters. Complex treatment of fruits
(apples and pears) with ELF EMF and the biopreparation
“Vitaplan” before dispatching for storage
allows preserving the biologically active substances –
the vitamin C and P-active substances – to the
maximum degree. Synergetic effect, appearing due to
the complex action of electromagnetic field and the
bio-preparation, allows decreasing the processing time
in the electromagnetic field
