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)
