Licensed collection and processing of artemia cysts from Kazakhstan

Artemia cysts accumulate in shallow, saline bodies of water, often near the coastline. The best time for harvesting is the seasonal lowering of the water level, when the cysts concentrate on the surface. We use a manual collection method - using small mesh nets or nets, and we also collect using pumps and filtration units.

After collection and pretreatment, artemia cysts must be properly transported in order to preserve their quality and viability. The optimal storage temperature is 0...+10°C to prevent premature hatching. The humidity is minimal to eliminate cyst hydration.

After transportation to the production workshop, artemia cysts are checked for compliance with quality standards. This stage is important for ensuring high survival and productivity of nauplius during incubation. Visual inspection and physical characteristics are performed. Humidity, buoyancy, and frequency are determined. Artemia cysts then undergo an incubation stage to determine the percentage of hatching quality.

Artemia cysts often contain mechanical impurities (sand, algae, organic residues). To remove them, salt washing is used, which helps to separate clean cysts from unwanted particles. First, a saline solution is prepared, then the cysts are immersed in it. Large impurities are removed mechanically (by nets or filtration), Small impurities are separated by filtration through a fine-mesh mesh (mesh size 100-150 microns).

After salt washing, artemia cysts contain a significant amount of water. Industrial spin in centrifuges is used to remove excess moisture and improve storage quality. The process lasts 5-10 minutes until most of the moisture is removed, then the sheets are unloaded in a semi-dry state (humidity 25-30%). The advantages of using centrifuges are that they speed up the water removal process compared to natural drying, reduce the risk of bacterial contamination, and increase shelf life by controlling humidity.

After removing excess moisture, artemia cysts undergo thermal activation, which results in increased cyst hatching (up to 90%), accelerated nauplius release, and reduced number of non-viable cysts. This stage is especially important for the industrial production of live feed.

After thermal activation, artemia cysts must be cleaned of salt residues and possible impurities in order to prepare them for storage or incubation. Fresh washing reduces the risk of salt deposits accumulating and improves the quality of hatching. The cysts are filtered through filters to remove fine particles and residual shells. If necessary, repeat rinsing 2-3 times. Final drying - the cysts are dried in special industrial furnaces to remove excess moisture.

After completion of all stages of treatment (purification, thermal activation and fresh washing), artemia cysts are packaged and packaged. This is necessary to preserve their quality, increase their shelf life and ease of transportation. Final drying of the cysts - Air drying chambers or vacuum drying at temperatures up to 40 ° C. are used, since the humidity of the cysts before packaging should not exceed 6-8%. Packing is done in cans or bags of 50, 100, 500 and 1000 grams for small orders, or in 20-25 kilogram multi-layer bags for large industrial batches. Also, at the request of the client, it can be packaged in other packages.
