C series Dryer
TRADITIONAL CONTINUOUS DRYER
Specifications
Available in various sizes and models with capacities from 12 to 79 t.
COMPONENTI
Air duct
The panels forming the air chambers are made of: mineral wool sandwich panels,
heated air section and saturated heated air section (prevents the formation of condensation and mulch inside the chamber).
Smooth interior and exterior walls.
Versions: Aluzinc-Galvanized-Precoated in various colours - Aluminium-Stainless steel 304.
Reinforcing uprights and ledges with rung ladders are installed inside the dryer for control and maintenance purposes.
Fans
The depressurised drying system, offering maximum attention to detail, is the most suitable for dust containment.
Each dryer is equipped with axial fans with variable pitch blades with different diameters, exploiting the machine's output and minimising consumption.
Zanin uses technologically advanced brands in the European fan sector to optimise the characteristics of its products.

Electrical cabinet
Dryers are equipped with electronic control devices.
Electronic control system to manage product humidity with air gauge.
Operating principle
The drying column is formed by an upper feed hopper and a certain number of modules inside which ducts are buried in the grain.
The grain drops by way of gravity in a zig-zag pattern.
The grain then hits a counter-current of warm air.
The air flow is then dispersed into the atmosphere.
The quantity of grain in outfeed is regulated by a pneumatic extractor.
The product is then collected in a discharge hopper.
