Tecnograin has been engaged in development and production of cereal drying systems, like continuous flow and energy saving grain dryers since 1987.
Equipments for grain drying: continuous flow and energy saving grain dryers
Two grain dryer models and a great versatility permit to our drying installations an easily adapting to very different products: corn, horge, rye, Indian millet, oat, coffee, wheat, paddy.
The schemes below show the operation of these dryers and their main differences.
For each grain dryer model two versions are available, according to the heat generator:
We emphasize the importance of some parts: the column, the unloading equipment, the operation in depression, the interception doors.
The column is specially made with stagged curved metal sheets by which you obtain a drying process at mixed flow. During its descent, the product passes by zones where it is "hit" by a flow of current and counter-current air, which grants the maximum homogeneity of drying and the best energy output.
The unloading equipment permits the descent of a great quantity of grain very rapidly, thus assuring a constant movement on the whole column and reducing the dust emission. Important detail: its structure permits the total cleaning during the passage from a product to another one.
The operation in depression involve a low consumption of electric current and the elimination of dusts in the work milieu. Particularly, the dryer fans are designed to have aeraulic characteristics appropriate for drying, while blades at variable step permit to regulate the air flow according to the product.
On demand, interception doors with pneumatic control may be installed down-stream of the aspirators in order to block the air flow during the draining phase. This grants a great reduction in environment pollution. Some extensions with a covering in acoustic material are available in case of noise problems.
Finally, let's talk about our leading-edge model, the Tecnograin continuous flow and energy saving grain dryer, which shows the best characteristics today available in the international sector. Its great technical characteristics make it an essential element for large companies.
