Abstract:
Now a day’s tea and coffee are the most widely used consumption product whole over the world
next to water. This paper is planned to prepare the general process of preparing solar thermal
system design to replace the traditional and the electrical tea and coffee making system. In the
process of doing this, planning to limit the things to be done are the most things to consider. The
basic issues under consideration to develop the whole research design are; design of solar
collector, thermal storage system and development of tea and coffee making mechanism
Dish collector of 3m aperture diameter standard has been selected for solar energy collection.
The 2D assembly model of tea –coffee making has been developed using solidworks software and
also the power produced by the collector is calculated using mathematical modeling and
validated using SolTrace simulation by comparing the power calculated with the power
developed through SolTrace. From that the heat flux reaching energy storage surface is
identified and used as boundary condition order to develop ANSYS software’s simulation of the
heating and cooling retention of thermal energy storage in order to identify melting and
solidification hour of the storage salt. This is done to know the time required for storage salt to
melt and also the time for the molten salt get changed completely to solid, which is energy
storage time.
At the end of the research well controlled tea and coffee cooking system in which all variable
such as temperature and cooking time are efficient, effective and economic is being developed.
Finally, with the developed machine it is possible to convert one liter water to steam in 15
minute for tea-coffee making purpose. In the process of ANSYS simulation the melting Hitec salt
has been seen and it is possible to melt 94.2% of the slat in less than 5 hour and the cooling
retention which is the storage time for thermal storage has been seen that, around 90% the salt
has been solidified with less than 3 hour and 36 minutes which shows us 90 of the salt can store
energy for around 3 hour and 36 minutes
