All the plants / herbs have very complex structure. Most of the
active ingredients present in the form of natural organic compounds.
The process of extraction for a particular compound or multiple compounds
are dependent on the solubility of the rich components in an extraction
media such as aqua (water) or organic solvent or a mixture of organic
solvents by using the principle of physical separation and the property of
solubility of those compounds in that particular extraction media.
The process and the plant design of extraction system is invariably
different from product to product and component to component. Its very
difficult to generalize a process to extract isolated compounds from various
herbs. From raw material to isolated compound, a series of processes will be
involved. In the first step of process, the rich compound(s) can be
extracted in a generalized manner with an extraction media. The second stage
is followed by purification and isolation by various physical / chemical
From a generalized extraction process, the rich herbal extracts can be used
directly in herbal formulations for herbal, pharmaceuticals, food and
cosmetic industries. Some of the herbal extracts can be used as natural dyes
for textile, leather, food and cosmetic applications as coloring matters.

Herbal Extraction Process
Vegetable Dyes Plant
offers vegetable/natural dye manufacturing plant. There is a big demand of
vegetable/natural dye in the whole world as it is a replacement for chemical
dye. Vegetable dye is used in textile as well as food industries.
The process involves extraction of colouring liquor from vegetable waste
like onion peel, pomegranate (anar), mango (aam), harda, etc. and then
concentration and spray drying to make powder.
This is a highly profitable project. Space requirement is only 300 sq.
