A study of several industrial heat requirements has identified several industries with favorable conditions for solar energy use, the most important industrial processes using heat at moderate temperatures are: sterilization, pasteurization, drying, hydrolysis, distillation and evaporation, rinsing and cleaning and polymerization. The study describes some important processes and the temperature range required for each of them.
The aim of this study is to develop and experimentally study a model of a solar water-heated drying device for drying ginger (Zīngiber) root and other medicinal plants. Models are available for separate subsystems of the drying system, but there is currently no complete system model for controlled, defined heliological drying for ginger root and other medicinal plants. In this paper, a model of a solar water-heated drying device for drying ginger (Zīngiber) root and other medicinal plants has been developed and studied experimentally. Using the model, the useful energy and temperature coming from the solar collector were analyzed. The appliance consists of a transparent solar flat collector, a drying chamber and an exhaust pipe. The plant was developed and tested for drying ginger root (Zīngiber). By creating a separate subfunction for a product, the overall model does not depend on the type of product used in the experiment, and the product can be user-defined. The sub-functions of product drying provide the initial conditions for the product itself, air and moisture flow in the air. This allows relative humidity to be re-passed through each zone and is critical for accurate modeling of the drying curves of each product. Variable product and air constructions are included in the product drying function to monitor the moisture content of the product on the pallets. However, the importance of modeling in optimizing results was highlighted. To display the conditions in the dryer, the system displays conditions such as temperature, humidity, and flow over time. To simulate drying curves, the moisture content of the product is determined internally. Graphs of relative humidity and heat exposure are plotted. The optimal operating mode of the solar collector has been developed. The advantages of other types of dryers have been studied. The efficiencies are presented in the form of equations. The graphs were compared with the experimental results. The solar collector model was analyzed to determine the outlet temperature and relative humidity, ambient temperature and relative humidity.
