Dryers Model 701 - Pennati Costruzioni Meccaniche S.r.l.

Our model 701 dryer has a rotary drum on a horizontal axis. The machine is also complete with a generator for hot gases, which are introduced either at an equal rate or in counter direction to the moist product to be dried, a fan, a separating filter, a continuous feeder for the moist material and the actual drying drum.
The product is dried by direct contact with the hot gas. The moist product is entrained directly inside the drum in the gas currents aspirated by the vacuum fan downstream of the filter.
The dryer, as well as the other components of the machine, is dimensioned in accordance with the required throughput.
The control system allows for continual adjustment of the operational parameters, so as to guarantee both the quality of the end product, as well as the simplicity of usage and operation and the system efficiency, by optimising fuel consumption.
The dryer is designed in accordance with specific requirements. It may have parts in stainless steel or refractory quality steel, if the temperatures or particular usage make this necessary. It may have cleaning systems for the feed coils if it is fed with mud. It may be plated or have internal cellular and stellar cross bracings. The roller, however, is always provided with internal flights which have differing angles to slow down product flow, thus forming a continuous cascade over the entire section of the tube where the hot gases flow.
