Direct Solar Dryer
“Direct Solar Dryers expose the substance to be dehydrated to
direct sunlight”
In this Dryer the solar drying is assisted by the movement of the air
(wind) that removes the more saturated air away from the items
being dried
Solar Natural Dryer
Cabinet type Solar Dryer
Solar Tunnel Dryer
Green House Solar Dryer
Indirect Solar Dryer
In indirect Solar Dryers, the black surface heats incoming air, rather than directly
heating the substance to be dried
Transpired collector type Hybrid(Solar-biomass) Dryer
Solar PV Panels
“A solar cell, or photovoltaic cell, is an electrical device that converts the energy
of light directly into electricity by the photovoltaic effect”
Solar Cooker
A solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize food or
drink
Solar PV Cell
Photovoltaic cell, is an electrical device that converts the energy of light directly into
electricity by the photovoltaic effect

Analysis Lab
The Spectroscopic analysis of the semiconductor and other geological materials is done for detection of metallic and non metallic impurities up to the level of parts per million (PPM) and parts per billion (PPB) level
ICP detects impurities using options of Atomic Absorption, Atomic Emission and Flameless Techniques
Gas Chromatograph GC analyses gases using FID and TCD detectors
Inductivity Coupled Plasma (ICP) SpectrometerGas Chromatography (GC)
