It is extremely important not to make a mistake with your choice grain dryers, because it depends on it.

At the present time, there are very common competing mines and
column (modular) dryers for grain. They differ in design and principle.

column type, but more economical in operation.
In a column grain dryer (usually produced in the USA, Turkey, as well as farmers)
European) warm air passes through a thin layer of grain located between the two.
perforated grates, and it goes out into the atmosphere together with what it managed to drink, then
there is moisture and dust. The increase in productivity is achieved by the increase
grate squares.
A mine with grain in a mine grain dryer (usually manufactured by Europe)
permeated with air channels "boxes", completely open from the bottom (no grates).
Air passes
through the grain from channel to channel, there is no need for high pressure,
since it is not necessary to blow the sieve, so the air is maximally saturated with moisture.

Another design difference of the Perry grain dryer, compared to
dryers of the column type, is the absence of screw mechanisms, что
