A small paddle wheel of diameter up to 0. Spirulina Cultivation Process : Cultivation can be started after water is fed into each concrete pond at a required height and after paddle wheels are installed. The water has to have the right pH value and alkaline by adding required salts at the required rate. Once the water has a standard micronutrient composition, the pond is ready for Spirulina seeding.
Ideally, for uniform growth and for uniform harvesting, 30 grams of dry Spirulina is added for every 10 liters of water. A concentrated live Spirulina culture can also be used as seeding the pond. In commercial farms, one pond is exclusively kept for rearing Spirulina as seed. This will reduce the regular purchase and the farm becomes self-sustain and also can sell live Spirulina seed to other farmers. The algae bacterium starts to double in biomass within three to five days.
The alga thrives growing by consuming the nutrients in the culture medium. Farmers have to continually check the nutrient content value and adding fresh water at regular periods for good production and for top yields. Farmers should be alert to control environmental conditions as this prevents the culture medium from contamination.
Cultures grow rapidly as well as perish rapidly when Spirulina cultures are not taken care of properly. The matured Spirulina changes from light to dark green in color. The concentration of algae and color of the algae is the deciding factor for when Spirulina should be harvested. The other way is by using Secchi desk to measure and it should be around 0. The water level in the pond should be maintained at 20 to 30 cm 25 cm is ideal water level height. As most of the ponds are open the evaporation of water will affect the cultivation.
Especially during summer, on an average thrice in a month, fresh water is released into the ponds to maintain consistent 25 cm water level height throughout the cultivation. Filtering of Culture Medium : As said earlier, the concentration of algae in the pond will be the deciding factor for harvesting.
In general, the pond will be ready for harvest after five days after seeding process is done. Different farmers use different methods to harvest Spirulina, this is because of the availability of material resources and finance. Whatever is the reason, filtration is carried out to harvest Spirulina. Culture is collected in a container and poured onto the cloth. The culture medium flows back into the pond, leaving Spirulina on the cloth.
The excess or the culture medium residues that still remains can be drained by applying pressure or squeezing. Farmers have designed various filtering process for the easy and quick process. One can get more information on the internet for various designs that can be used to reduce manual and quick harvest processing work.
After filtering, the collected Spirulina is thoroughly washed in distilled water to remove any traces of salts, contaminants, or culture medium residue. Once the cleaning is done, the water content is further removed by squeezing or pressing and is ready for drying.
Freshly harvested Spirulina will be at its best in its nutritional values. Fresh Spirulina cannot last more than 2 days, hence it needs to be dried to preserve its nutritional values and to last for a longer duration. Drying of Fresh Spirulina : Spirulina, when dried, will last for many months and also the nutritional content in it can be preserved.
For quick drying, the Spirulina mass is kept inside the kitchen press grater and then pressed into thin strands on a long clean cloth under the sun. This helps in quick drying. The kitchen press comes with various discs of different hole sizes in it. Condensed spirulina which has been separated from the culture medium is placed on vacuum dehydration filter and washed repeatedly with clean water and dehydrated. Production Process Safety Strong drugs may have strong side effects. On the other hand, spirulina is a natural food which have been used as food since ancient times.
It is thus gentle and harmless to the human body. The method of the cultivation and production is also safe and hygienic. Regular intake of spirulina increases anti-viral activity, stimulates the immune system, reduces kidney toxicity, improves wound healing and reduces radiation sickness. Spirulina is a perfectly safe natural food which provides quick energy and nourishment. The recommended daily intake is grams, but if you feel like consuming more, go ahead. Spirulina powder can be added to fruit or vegetable juices or to dishes to enhance nutritional content.
It is tasty in soups, salads, pasta, or mixed with yoghurt. Spirulina Crunchy is nice to eat as a snack or as a seasoning on your dishes, bread or salads, only avoid cooking it as a lot of nutrients esp. Special tip: make a fresh lemon juice or use lemon syrup , add a teaspoon of spirulina, stir well and drink it straight away. The vitamin C of the lemon spirulina doesn't contain vitamin C will help with absorbing the nutrients.. Spirulina capsules vegetarian and tablets are convenient to take at any time of the day.
Last updated: Aug 9, Spirulina farm. Write to Spirulina. And then there are the essential Omegafatty acids, something normally associated with fish. Spirulina has always been a special case: Indigenous people harvested algae from flat, sub-tropical to tropical waters with a high salt content. This was turned into blue-coloured cakes and it is even said that marathon runners took it for extra energy.
People living close to Lake Chad show low levels of malnutrition despite living mainly on millet. Modern industry has found a new way to grow Spirulina. Aquacultures, so-called open ponds, are common. To harvest it, the culture is pumped through a filter or a centrifuge and then dried in the sunlight or with hot air. It is an enclosed system, which keeps the algae from contamination by animals, bacteria or dirt.
