BASED ON THE SAME HIGH TECHNOLOGY CRITERIA OF THE DIRECT FIRE DRYERS, ZAFFRANI HAS ALSO REALIZED INDIRECT FIRE DRYERS. THE AIR IN AEROTHERMAL UNITS WITH INDIRECT HEATING IT PASSES THROUGH A TUBE BUNDLE HEAT EXCHANGER WHERE SMOKE CIRCULATE. HIGH PERFORMANCE AND UNEXPECTED QUALITY REPRESENT THE CHARACTERISTICS OF THIS HIGHER LEVEL MACHINERY THAT GUARANTEES THE SUSTAINABILITY AND STORAGE OF THE PRODUCT OVER TIME.
Maximum adaptability
The Zaffrani indirect fire dryer is easy to handle; the modularity of the structure together with the simplicity of assembly allows the machine to be adapted to any territorial context.
High versatility
The particular constructive form allows to meet the daily needs of reducing transport costs.
Excellent yield
The use of high quality components, attention to details and constant research aiming at improving performance allow us to obtain high yield in terms of dried product according to the burner’s time and consumption.
In accordance with EU guidelines
The presence of the heat exchanger offers an adequate solution to companies that produce seeds or flours intended for human consumption as this dryer fully complies with all the rules imposed by the EEC on the safety of food products.
TECHNICAL CHARACTERISTICS
HEAT EXCHANGER FOR EXCELLENT QUALITY
The operation of the heat exchanger is based on the principle according to which the flow of cold air is compressed by the fan in the exchanger itself, investing the entire surface heated by the burner without coming into contact with waste fumes and therefore without residues resulting from combustion.
AIR MIXING SYSTEM FOR A CONSTANT TEMPERATURE
The efficient hot and cold air mixing system provides one single circularly homogeneous airflow in the dryer at constant temperature, thanks to the special diverted contained inside the air diffuser. This guarantees homogeneous heating of the product and prevents irregular drying.
CONTINUOUS PRODUCT MIXING
The product mixing is continuous, even, and occurs inside the machine. This process is possible due to the presence of mixing arms that convey the product close to the central screw, which conveys the product from bottom to top.
