RECIRCULATING RR DRYER

recirculating dryers

The Ravaro RR recirculating dryer is suitable for drying all kinds of leguminous cereals (paddy rice, corn, soybeans, barley, wheat, rye, oats, sunflower seeds, canola, sorghum, peas, coffee, and others).

The product falls 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 through the whole section of the column, preventing the formation of preferential currents.

In the first drying zone, the product is struck by warm air and releases most of its moisture.

In the highest part of the dryer (recovery layer), the product is not affected by any air flow (lozenges are not present, only the sheet metal container). In this zone the innermost moisture of the grain tends to migrate towards the outside facilitating subsequent evaporation and improving drying homogeneity.

Finally, during the subsequent drying stage, the residual moisture is removed until the desired final value is achieved.

CONTINUOUS RC DRYER

continuous dryers

The Ravaro RC continuous dryer is suitable for drying all kinds of leguminous cereals (paddy rice, corn, soybeans, barley, wheat, rye, oats, sunflower seeds, canola, sorghum, peas, coffee, and others).

The product falls 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 through the whole section of the column, preventing the formation of preferential currents.

In continuous mode, the dryer does not have a recovery layer, but is configured (number of drying layers, and extraction speed for the product, drying temperature,) in such a way as to eliminate a predetermined percentage of moisture

The product passes only once through the drying column and is immediately stored.

In the first layers, the machine is cooling through shutters fitted to the heads and the dryer's fan casing
