Cleaning of bottles and cases with solar integration

Different process technologies exist within industry, which lead to several possibilities for the integration of solar heat. Based on the general classification of industrial heat consumers drying processes are assigned to the category “Thermal separation processes”. By consideration of the conventional heat supply, different integration concepts are possible.

PL_E_PM - external HEX for heating of product or process medium This integration concept is basically the easiest since an additional solar driven heat exchanger is installed in serial to the conventional heat exchanger to heat a product or process medium (e.g. water, lye, fruit juice, etc.). It can be applied to all three categories of heat consumers “(pre)heating of fluid streams”, “heating and maintaining temperature of baths, machineries or tanks” and “thermal separation processes”. The serial integration of a solar driven heat exchanger can be realized in a way that only part of the entire product or process medium stream is heated up and hence heat exchanger surface, pump and pipe dimensions can be kept small.
