Lessons learned |
|
|
Initiative |
India is a major producer and consumer of pulses. There are around 1400 pulse processing units in the country and it offers employment in rural and sub urban mass. Due to the space constraint all pulse mills have shifted from open yard drying/heating method to conventional dryer heating method. The preferred fuel for processing pulses is diesel and in some cases coal (or) firewood.
|
|
Integration methodology |
A 230 m2 solar air heating collector was installed on the south facing roof of the factory. Solar air heater draws cold air and heats it to 65 deg C by exposure to sun’s radiation.
|
|
Crucial Interfaces |
A temperature controlling device is used to prevent the overheating of the product.
