Thermal Energy Storage Based Solar Drying Systems A Review

Developing efficient and cost effective solar dryer with thermal energy storage system for continuous drying of agricultural food products at steady state and moderate temperature 40 75 c has become potentially a viable substitute for fossil fuel in much of the developing world.

Thermal energy storage based solar drying systems a review.

Solar dryer based on thermal energy storage materials is quite effective for continuously drying agriculture and food products at steady state in the temperature range 40 c 60 c. Solar dryer based on thermal energy storage materials is quite effective for continuously drying agriculture and food products at steady state in the temperature range 40 c 60 c. This paper mainly presents a review on the important contributions made so far in the field of solar drying systems based on the thermal energy storage medium with a focus on recent updates in. Solar energy storage can reduce the time between energy supply and energy demand thereby playing a vital role in energy conservation.

The entire review for solar drying with thermal energy storage can be discussed in two subsections. The entire review for solar drying with thermal energy storage can be discussed in two subsections. In other words solar energy storage unit can be called as the sub renewable sources of energy 6 7 there are various kinds of phase change materials but paraffin has been widely used for latent heat thermal energy storage system because of their large latent heat and proper thermal characteristics such as no super cooling low vapour pressure. Such dryers have globally become a potential viable substitute to the solar dryers based on fossil fuel due to the utilization of clean energy resources and cost effectiveness.

This paper mainly presents a review on the important contributions made so far in the field of solar drying systems based on the thermal energy storage medium with a focus on recent updates in thermal energy storage technology available in terms of materials capable of storing heat as sensible and latent heat. When compared to the energy efficiency of other thermal energy systems a concrete thermocline is shown to be less efficient than a molten salt two tank energy storage system by less than 5.
