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.

5

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.

6

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.

7

Technological peculiarities of the offered aeration dryer in comparison with analogues

• Horizontal, shorter in size in comparison with vertical and less power-intensive 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.

8

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.

9

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.

10

• Creation of dealer system for advertising and sealing

11

Development Costs Development of the aeration dryer prototype consists of the

following work stages:• analytical research;• laboratory experiment preparing;• laboratory experiment to option the aeration technology

parameters;• issuing of design and engineering documentation;• preproduction work for new details and assembly unit;• manufacturing of the prototype and purchasing equipment for

the field tests;• field tests of the aeration dryer;• refinement of the dryer design by the test results.

Total development cost for the aeration dryer prototype of 100…150 ton capacity amounts approximately 0.9 million of USD.

12

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.

13

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.
