Rotary cooler dryer

ROTARY COOLER DRYER

The ERF rotary dryer cooler is used in the drying and cooling of pellets, flour, flakes, coffee and cereals in general.

In the feed industry, it is used in the processing of pellets and cereal flakes.

Thanks to their simple and rational design and robust construction, our modular rotary dryer-coolers are characterised by a high degree of reliability and efficiency.
In small installation spaces, they ensure optimal product handling in a short time.

STRENGTHS

• Effective and highly customisable process;
• Quick product change;
• High reliability;
• Low maintenance and access from outside to machine components;
• Easy installation in small spaces.

TECHNICAL FEATURES

The new rotary cooler dryer, which has been completely redesigned in its construction, is developed vertically in a modular manner.
In standard sizes, cylindrical modules are available in diameters of 2.2, 2.5 and 2.8 metres and range from a minimum number of 3 up to 8.

Each module consists of:

• Outer ring consisting of press-folded flanged panels that can be completely dismantled, equipped with an access hatch on the inside and inspection hatches;
• Impeller consisting of a flanged rotating shaft and product support plane, made up of self-cleaning circular tilting sectors in slotted sheet metal;
• Product layer levelling device;
• Safety and product passage control sensors to ensure rapid product change.

The drive consists of a geared motor, safety coupling and gearbox directly keyed to the machine shaft.
The rotation speed, variable via an inverter, allows the treatment time to be adjusted.

At the base of the machine is the inlet module for cooling air, in the centre the inlet module for hot air, which is suitable for drying the product.
In order to achieve high drying temperatures, the two air flows can be regulated by a by-pass system on request.

OPERATION

The product is loaded from above and as it passes through the various stages it is hit by the countercurrent air flow.
The first modules are dedicated to drying, the last to cooling.
Thanks to the uniformity of the layer and the tilting that the product undergoes as it passes from one stage to the next, the drying and cooling process inside the Fragola rotary cooler dryer is particularly effective.
