Operational throughout North and Central Italy, particularly in regions such as Emilia Romagna, Friuli, Venezia, Giulia, Liguria, Lombardy, Marche, Piedmont, Trentino, Alto Adige, Tuscany, Umbria and Veneto, Ravaro Costruzioni Meccaniche has been operating since 1967 in the design of drying and storage systems for leguminous cereals. Confident that innovation is the first step towards real progress, we have studied, conceived and developed new models of high-efficiency dryers.

RR recycled dryer

The Ravaro RR recycled dryer is suitable for drying all types of leguminous cereals, such as:

paddy rice;
corn;
soy;
barley;
wheat;
rye;
oats;
sunflower;
rapeseed;
sorghum;
pea;
coffee.

Specialists in designing drying systems, we at Ravaro have designed a new system for even greater efficiency and efficiency.

The drying operation within the RR recycled dryer has three phases:

The product descends by gravity through a series of staggered lozenges that produce a zig-zag movement and continuous mixing. The geometry of the lozenges guarantees a uniform descent over the whole section of the column, avoiding the formation of preferential currents.
In the first drying zone, the product is hit by hot air and yields most of the moisture. In the highest part of the dryer (called tempering ) the product is not affected by an air flow (there are no lozenges, only sheet metal boxes). In this area, the inner moisture of the grain tends to migrate towards the outside - facilitating the subsequent evaporation and improving the homogeneity of drying.
Finally, during the subsequent drying phase, the residual moisture is removed up to the desired final value.

Continuous RC dryer

The RC continuous dryer developed and assembled by Ravaro, a reference company in the design of drying systems, is suitable for drying all types of leguminous cereals.The difference with the recycling dryer lies only in the continuous mode: the dryer does not have a tempering phase, but is configured (number of drying slices, product extraction speed, drying temperature, etc.) in a way so to be able to eliminate a predetermined percentage of humidity.

The product passes only once inside the desiccant column and is immediately stored.

In the first parts of the machine, cooling takes place by means of shutters placed on the heads and in the dryer's wind box.
