Title: Ende avours in the development of mixed feed industry

Summary: The decreasing production costs in mixed feed industry
havestimulated great changes, all over the world, in the size,equipment and
ownership of mixed feed industry. Automation offactories has become
compulsory for survival, which has, at thesame time enabled an increase in
capacity to over 100 t/h.Multinational companies cross the continents and
dictate theprice of production.
In 1991 the world production of mixed feeds was estimated atabout 600
million tonnes. Europe produces about 50 %, NorthAmerica 23 %, Latin
America 7 %, the Middle East and Africa 3 %,while Asia and the Pacific area
produce the remaining 17 %. Thecountries of the EC contribute with 18 % and
other Europeancountries with 32 %. The former USSR produce 145 million
tonnes,which probably includes the overall feed production, not only
theindustrial production of mixed feeds.

Summary: Soybean final processing is performed on different ways due
toinactivity of its harmful components as trypsin inhibitor.Trypsin
inhibitor is termo unstable and its inactivity isachieved by means of heat,
water, pressure on a bean. Theachieved effect is closely connected with the
time impact of eachsingle factor.
Each single mentioned factor, exp. heat, is due to achieve thedetermined
aim under certain circumstances.
Negative effects on the other useful sead components can beachieved by
inadequate final processing.
Chemical final processing has been used recently, preserved bythe name
SUPRO. SUPRO is a process by which vegetable proteinturns to be adaptable
by chemical reactions; unreturnablydenaturalized. Final processing expences
depend on the quantityand the kind of energy which is used. It's cheaper to
use heatthat mechanic energy, although it's hot proved to be
morefavourable.

Summary: Damage to grains occurs because of the high level of
mechanization of certain working operations in handling grains through all
the stages of production. Also, by applying new finishing methods enabiling
increase of digestibility, the dynamic resistance of the grain changes. The
breakage in the total quantity increases with the grains passing through a
series of transport devices. The work compares the dynamic resistance of
the maize grain Hybrid Bc 492 in standard drying method with dynamic grain
resistance after applying the "cooking" technique with perforated and
nonperforated pericarp of the grain. In investigating the dynamic
resistance and the potential of genetic resistance of maize grain a device
specially made for this purpose was used. The device can simulate kinetic
conditions affecting the grain in machine harvesting, during transport, in
storage, etc.
Keywords: dynamic resistance, corn kernel, "cooking" technique, standard method, drying, perforated, nonperforated.

Summary: In this paper kernel of hybrid Bc 492, FAO group 490,
yellow dent corn was given a mathematical model of drying corn, in the
investigation the first sample of corn kernel was dried without any
treatment. The second sample was cooked before drying and the third one was
perforated and cooked before drying.

Summary: In this paper drying velocity of five different hybrids of
corn kernel (Bc 468, Zg 43-28, OSSK 407, Bc 492, Bc 48 W) is given. All the
hybrids are from FAO group 400, subspecies - dent yellow corn. Hybrid Bc
468 was dried shorter at the air drying temperature of 130 C for about 83,3
% than hybrid Bc 492 at the same temperature. When the air drying
temperature was 110 C this differences was even greater. Hybrid Zg 43-28
dried faster than hybrids Bc 492 and OSSK 407 by about 125 percent.
Keywords: drying, dent yellow corn, FAO group 400.

Summary: The work treats of researches into initial appearance of
fluidization varying within a grain layer (bed) subjected to drying. By
measuring the working air fluidization inducing velocity in a layer it has
been established that its level also depends on different thickness of
drying material on the drying grain properties. By changing the mentioned
characteristics, the fluidization point also changes. On a laboratory
dry-klin model the extent of all the consequential factors have been
measured, especially, as the essential element, the diminishing pressure
drop in a material layer. Based on the results of these measurements, as
well as on a theoretical analysis of the process, the volume and porosity
of the fluidized layer has been estimated. With a veiw to enable the
application of the pattern of the "working" air streaming through a layer
of biological material, it was indispensable to exchange a grain for some
of the common geometrical forms, in this case sphericality has been chosen,
that is, the coefficient of the adaptability of a body to a ball. The
primary research into forty-eight samples of different initial drying
velocity levels (0.8; 1.1; 1.3 m/s) as well as of air temperature levels
(85; 110; 130 C), with the varying initial moisture of the samples, had
develooped parallelly with primary researches. Owing to the extent of the
researches, this work deals with samples of only one temperature level (110
C) and one air streaming velocity (1.1 m/s). Because of the diminished
sizes of the grains the level of the biological material changed its
thickness and its porosity. In these drying conditions a linear change of
the layer thickness depending on the moisture of the material has been
established. The work may also serve as a basis for the construction of
industrial dry-kilns, as well as to equip them with measuring and
regulating equipment. A mathematical model of the interdependence of the
mentioned dimensions for the establishing of the initial fluidization point
has been proposed, as well as an introduction of additional dimensions of
interdependence of the layer pressure drop diminishment and the "working"
airflow velocity into automatic system for the complete control of the
industrial maize dry-kilns.
Keywords: airflow, pressure drop, fluidization, moisture content, drying, corn kernel, sphericality, porosity,
