Drier for Spirulina
Dear Sir,
We are using both Tubular Solar Drier as well as Fuelwood based Drier to process our horticultural produce like Arecanut, Coconut, Pepper, Cardamom, Nutmug, etc. The cost of constructing Tubular Solar Drier varies between Rs.75/= to Rs.85/= per Sq. Feet. That of the Fuelwood Drier depends upon the quantity of the produce to be dried. If you infom the exact quantity to be dried, then I shall provide the cost of Fuel Wood Drier also.
In any drier, we should see that there is proper ventillation, in addition to heat. Without air-circulation it is difficult to properly dry the agri-produce.
