Problem Description & Market Need
• 40% from 40 millions tons of grain growing at Ukraine is
harvested in moist state. Due to lack of drying equipment at a
reasonable price and effective grain drying technologies 6
millions tons of grain is lost because of spoilage. It costs $0.8
billions for Ukrainian economics.
• According to statistics only 30% of grain enterprises are
provided with drying capacity. Conventional drying equipment is
not available for most of small and middle farms at Ukraine and
others countries because of its high cost and power inputs
during operation. Farmers need inexpensive and effective
dryers.
• The potential market of the dryers at a reasonable price and
operation costs with possibility to cover its cost quickly is
practically unlimited in Ukraine as 6…8 millions of harvesting
grain are not provided with drying equipment.

Technical Merits
The proposed aeration in-silo dryer has the following
advantages in comparison with thermal dryers afforded at the
market:
• obtainable price (approximately half as much as thermal dryers
prices);
• high quality of drying for grain and seed;
• possibility of earlier harvesting on 1…2 weeks;
• replacing expensive and faulty fuel energy carrier with
economically priced fan power;
• environmentally appropriate and fire safety drying conditions;
• carefule grain finish drying after imperfect thermal drying;
• ease of assembling and handling;
• not high operation cost;
• quick payback (during one year) due to the obtainable price and
low (10 times less in comparison with the thermal dryers) power
inputs.

Description of dryer design and operations
The proposed aeration dryer is designed as conventional grain silo. Its
bottom can be conical or flat. A perforated multi-sectional air distributor
is installed on the bottom. Ducts of gas jetting system feed the air
distributor.
• The gas is purged through the air distributor sectional layerwise. Having
processed grain the gas is removed outside the dryer through a slot gap
between the roof and sidewall sheet.
• The dryer construction provide enriching the air feeding grain bulk with
ozone which has properties of both disinfector and drying agent. To
improve the air drying properties there are systems for its drying and
heating.
• To simplify dryer assembling and operation processes it is provided with
collapsible prefabrication sectional bottom.

Technological peculiarities of the offered aeration
dryer in comparison with analogues
•
•
•
•
•
•
Horizontal, shorter in size in comparison with vertical and less powerintensive way of gas movement using anisotropic properties of grain body
resistance to air flow.
Providing of moistened air removing from the dryer without its repeated
contact with dry grain.
The dryer design provides its rigidity both to internal loading from the grain
weight ant to environmental stress that allows applying dryers with the
height much more than the diameter.
Opportunity of feeding any height of grain bulk with gas of identical initial
characteristics with providing level-by-level adjustable on speed purge of
the bulk;
Exception of an opportunity for reproduction and further development of
pests in moist grain and maintenance of its qualitative parameters both
during drying and the subsequent storage in a dry condition.
Reduction of time and labor input of bottom assembly due to use of factory
manufactured section elements without application of building equipment
and concrete works.
7
Experimental results
•
Researches of the preparatory grain fumigation with the
ozonized air are fulfilled with the positive results.
•
Processes of the gas moving inside the aeration dryer and
moisture removing are studied with help of developed
calculation model.
•
Two aeration dryer imitators of 200 kg capacity are
manufactured. Equipment for creation and monitoring of
necessity medium inside the dryer as well as drying
equipment is prepared. The tests will be begun in November
of 2006.
•
Engineering documentation for manufacture of field aeration
dryer prototype of 18 ton capacity is issued. The prototype will
be manufactured and prepared for the field test in February of
2007.

The stage of development and the international
patenting
• Dryers’ design and grain drying technologies have been
studied by patent and subject literature;
• 16 technical solutions the closest to the proposed dryer
have been selected to use as analogs and prototypes;
• Application materials on the invention (drawings of the
dryer design, the description of its operation and the
patent formula) have been prepared;
• The application materials on invention have been
discussed preliminary with a patent agent for their
completion according to the international patenting
requirements and submitting to the State patent
association of Ukraine.

Commercial potential
Aeration dryer has all opportunities to win at the
trade market owing to high technical and
economic characteristics, parameters of quality
and ecological compatibility as well as
replacement of expensive energy carriers in
technological process of grain and seeds drying
such as natural gas and mineral oil by
inexpensive energy of the fan.
12
Targeted Market Segment
The aeration dryer may be widely adopted at:
• Seed-farming enterprises for:
 carefully and pollution-free seed drying with ambient air;
 germinating power stimulation and increasing the crop capacity
(conceivably on 10…15%) due to seed processing with ozone.
• Small and middle farms for:economical
 drying small grain batch;
 Economical drying (without applying of expensive fuel).
• Large grain enterprises for:
 Finish drying after incomplete thermal drying to abate power
inputs;
 Providing possibility to begin harvesting 1…2 weeks earlier with
furthering grain ripening during drying process.
