Hello sir,
1.Sprirulina mass production methods
in India, the Murugappa Chettiar Research Centre in Chennai has developed the technology and this has
been successfully propagated on a large scale in the rural areas of Pudukottai district of Tamil Nadu. For
instance, “mud pot” spirulina production uses a medium consisting of a biogas slurry, 2
–3 g of sea salt or chemical medium (potassium dihydrogen phosphate , cooking soda and sodium chloride) and pure
spirulina culture. The mud pots are buried up to their necks in the ground, filled with water mixed with
the medium and a small quantity of pure spirulina added. The medium has to be stirred 3 to 4 times a day
as the spirulina cannot grow in stagnant conditions . The pots have to be exposed to sunlight as the spirulina takes 3 to 4 days to mature. The mature spirulina (when the pale medium turns into dark green) can be harvested by a simple cloth-filtration. After
washing the spirulina in fresh water (to remove the adhering chemicals), it can be directly mixed with chapatti dough, chutneys, noodles, pulses, vegetables etc. Spirulina can also be preserved by drying, which must be conducted immediately in order to
preserve its quality and value .
2. Investment cost for 1 AC
pond cost is around lower side it requires 3.0 to 15 lakh for establishing one acre of and you can expect 300 kg of yield every day cost of nutrients is Rs.15000 to 20000 depending on local condition.
3. solar drying machine is good although electric dryers are available which are costly.
