Food Processing

To optimise product drying such as biltong we can reduce the trial and error time by providing a drying approach which tackles  key parameters in drying food.  Temperature, Humidity, airflow and handling methods are key considerations. chart

The use of desiccant dehumidifiers for product drying in a bypass to recirculated air.  The heat given off by the desiccant is adequate for heating the room and therefore cooling equipment is needed to avoid over cooling.  As different products each have their own  drying characteristics, it is important to know their drying profile to make an initial selection. Initial evaporation rates are usually substantially more than the calculated average.

Simple measurements in the change in weight over time will allow for oversizing, where some drying trend and initial moisture loss test will help reduce the equipment sizing.
