Study of Temperature Profile of the Solar Pyramid Dryer

The experiment was conducted at ‘Energy Park’, Department of Electrical and Other Energy Sources CAET, Dr. Balasaheb Sawant Konkan Krushi vidyapeeth Dapoli, Dapoli. The readings of temperature inside the dryer has been taken from 9:00 AM TO 5:00 PM with interval of thirty minute. It is recorded that maximum temperature inside the solar pyramid dryer was at 12:00 noon that is 55.5 0C and corresponding solar radiations where 552 W/m2.After analysing the temperature pattern from the graphs we can say that the temperature of air inside the dryer at various places varies such that, temperature of air at bottom of dryer was minimum, and it goes on increasing as the air moves from bottom to top of the solar pyramid dryer. Subsequently the maximum temperature found at the exhaust of the solar dryer. The average drying temperature is found to be suitable for drying of fruits and vegetables.
