Artemia is a good food for fish, shrimp and crabs. In recent years, due to overfishing, the production of Artemia eggs has been declining year by year. The obtained Artemia eggs also contain a lot of silt and sand and hatched eggs for Artemia. Bring some difficulties. In order to remove the sediment in the Artemia eggs, the harvesters often use sieve cloth to screen for Artemia eggs. The Artemia eggs screened in this way are of low purity and still contain some fine sediment, and the efficiency is very low. If salty solution is used for panning Artemia eggs, the sediment contained in the eggs can be removed at a time, and high purity Artemia eggs can be obtained, and the operation is simple and efficient. The operation process is as follows:
Firstly add a salt solution with a concentration of about 2% in a cement tank with a volume of 5 to 10 cubic meters or a tank of 0.5 to 1 cubic meter or other large container (water temperature is 20 to 22 degrees Celsius) The amount of solution added under the conditions does not exceed 2/3 of the volume of the container, and then put into the Artemia eggs containing sediment (the amount of eggs laid is slightly less than 1/3 of the volume of the container), stir with a wooden stick or other tools The egg is immersed in salt solution and allowed to stand for 5 minutes to 10 minutes. The egg and sediment are completely separated. Then, the fish is gently floated on the salt solution using a flat-bottomed hand-made net (made of 40-mesh sieve cloth). The surface of the Artemia eggs, and then stir the bottom of the pool with a wooden stick, so that because of mixing into the sand and sink into the bottom of the pool of eggs once again float, let stand for a few minutes and then gently picked up eggs, so repeated several times until it will The eggs are completely separated from the sediment. The dried Artemia eggs were put into bags after being dried, and the sediment sinking into the bottom was removed at the same time, and then the next batch of Artemia eggs was panned. Each time you use a salt solution, the number of pan-Amoy eggs used for panning should be determined by the amount of sediment contained in the Artemia eggs. The content is large and the number of uses is small. Otherwise, it can be used multiple times. Generally 2 to 4 times can be used.
Cosmetics are compound mixtures made from various raw materials after reasonable blending and processing. There are many types of cosmetics raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: base raw materials and auxiliary raw materials. The former is a main raw material of cosmetics, which occupies a large proportion in cosmetic formulations, and is the main functional substance in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other characteristics to cosmetics. These substances are not used in large amounts in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production processes such as heating, stirring and emulsification.
