Drying complex universal 2011 (for loose materials)
Experts predict that Ukraine has a
unique opportunity over the next
few years to be on a par with the
world's leading agricultural market, and the latest trends show that, and we are ready to
take an active part in the processing
of agricultural products, namely, in the
modernization of the mine elevator
dryers, by replacing gas, diesel, fuel oil, as a drying agent.
Almost all of the traditional dryings that use heated air as a drying agent
and that are used at the moment are dryers of convective type, in which the air
transfers heat to the grain and removes evaporating moisture. This drying
method has certain disadvantages relating
to inefficient use of energy
equipment, such as
the drying method is inevitably accompanied by heat loss to heating designs and
the environment, as it leads to
overheating of the grain and does not contribute to the complete
suppression of primary microflora.
An infrared drying method has significant advantages over
convection type driers,
and it works by the principle that
the moisture in the grain absorbs infrared rays
and heats i.e. energy is supplied directly to the moisture, and this achieves high efficiency and economy. With this principle, there is no need
to significantly raise the
temperature of the dried grain,
and the evaporation process can
be intensively lead at the temperature (45-100)
⁰C.
Low temperatures do not heat the machine, i.e. there
are no heat losses through the
walls, ventilation. At the same time,
infrared radiation makes the
process environmentally friendly,
as there is no deleterious effect on
the grain by carcinogens from combustion.
The infrared
radiation is harmless to the environment and human
health, as well as the equipment used with it.
We offer you
the innovative
development of the domestic producer - drying complex universal.
The principle of operation of the drying complex universal is
the focused infrared heating through metal
which becomes transparent to
infrared radiation at a temperature of
45⁰ C. As a basis we
took the principle of drum drying. By heating the dried material by heating
with infrared, moisture comes out from the inside of the material, forming the perspiration
on the surface, which locks the further passage of the infrared beam and
further heating. On the metal surface moisture evaporates actively ⁰ at 45 C, and
the dried material is heated from the inside!
The construction rotates, removing moisture from the surface of the
material, making it possible to further passage of the infrared beam. Properly chosen ventilation increases the sampling rate of moisture twice. Variable
speed allows you to control the
output of humidity. The temperature is set by the mode.
When adjusting all the parameters we have versatility.
Drying process is controlled by an automated control system, which provides:
- automatic program
start and stop all the mechanisms
of the line in
the desired sequence;
- support of security and emergency locks;
- automatic control
and monitoring of process
parameters;
- indication
of the equipment work and controlled
parameters.
Automated control system provides for work in two modes: manual and automatic. The complex of sensors
monitors the stability of line
work and, if appropriate, blocks those
or other mechanisms.
