ERCL    Dryers

Operation
The drying colum is formed by a loading hopper and a number of modules with internal conical ducts immersed in the cereal, which descends by gravitational force, with mixed and crossing current movement. The cereal is hit by a counter current of hot air, which exits, part of it in the environment and part recycled.
The quantity of cereal exiting is pre-determined and regulated by a pneumatic extractor. Then the product is collected in an unloading hopper. From the unloading hopper the cereal, still hot, is sent at intervals to the recovery area below and then to the cooling area for slow cooling.
The extraction area is one, regulated by several pneumatic extractors so as to make the exiting mass of dried product as homogeneous as possible.

Fans
For drying, with maximum attention to details, the depression system is the most suitable because of dust containment. Every dryer is equipped with a fan or fans, fixed or variable blade axial type, having various diameters to fully exploit the machine yield with less consumption. ZANIN F.lli makes use of technologically advanced marks in the European fan sector to optimise the characteristics of their products.

Air ducts (Version 1)
The panels that form the hot air and saturated air chambers are built of:
sandwich panels in mineral wool for the hot air part;
sandwich panels in polyurethane for the saturated air part (avoids condensation and mulch inside the chamber).
The walls are smooth both inside and outside.
Versions are: Aluzinc - Galvanised - Painted in various colours - Aluminium - Stainless steel 304.
The inside of the dryer is built to accept reinforcing standards and galleries with a rung ladder for checking and maintenance.

Air ducts (Version 2)
The panels that form the hot air and saturated air chambers are built of:
Smooth pressed Aluzinc sheet metal, insulated in the saturated air part.

For natural drying, time has always been essential. The ERCL DRYER is an absolute innovation in the drying system.

THE REASON FOR QUALITY For the same production, drying times vary considerably (see chart above). The time required inside an ERCL dryer is much longer; by favouring recovery the following results are obtained: less flawing of the product; less electricity consumption; less fuel consumption; higher protein value; more specific gravity; a healthier product; excellent warehouse storage.
